MIL-DTL-5015 Connectors
MIL-DTL-5015 is the classic threaded AN-type circular connector family for rugged power, signal, and control wiring. Buyers still search the MIL name even though many current drawings and catalogs point to SAE AS50151 equivalents.

What MIL-DTL-5015 Covers
MIL-DTL-5015 covers heavy-duty threaded circular connectors used for power distribution, control wiring, and mixed power/signal harnesses. The family is older and physically larger than newer miniature connector specs, but it remains common because the part ecosystem is broad and familiar.
The specification includes solder-contact and crimp-contact series, many shell styles, environmental classes, and insert arrangements with a wide range of contact counts. Many users also refer to these as MS, AN, or 5015-style connectors.
For harness work, the key decisions are shell size, insert arrangement, series, class, contact style, wire gauge, clamp or backshell, strain relief, environmental sealing, and mating-part compatibility.
MiniProto RoleBuilt Assembly
OEM pages from Amphenol, Glenair, and similar manufacturers sell connector parts. MiniProto turns the selected plug, receptacle, contacts, backshells, wire, labels, and test requirements into a built harness assembly with prototype-friendly ordering.
MIL-DTL-5015 Shell Size And Insert Arrangement Table
Representative arrangements for connector selection and quoting. Final part numbers still depend on shell style, class, finish, keying, contact gender, and backshell choice.

5015 Drawing-To-Build Quote
Send the MS or AN callout and we will map it to a buildable harness package.
Request A QuotePrototype-Friendly Assembly
Parts are only half the job.
MiniProto is set up for low-volume and prototype harnesses: connector sourcing, wire cutting, labeling, crimping, continuity checks, and IPC/WHMA-A-620 workmanship inspection practices. Typical lead time depends on connector availability and assembly scope.
Legacy Support
We can quote against old MIL-C-5015, MIL-DTL-5015, MS, AN, and SAE AS50151-style drawing callouts.
Power Wiring
Large-gauge wires, power contacts, strain relief, and labeling are handled as an assembly problem, not just a connector purchase.
Test
Continuity, point-to-point documentation, and workmanship inspection can be included for prototype and low-volume builds.
Sourcing
Common parts are quoted quickly; obsolete, finish-specific, or class-specific parts are checked against live supplier lead times.
Series And Variant Choices
Series ISolder
Traditional solder-contact 5015 connector family. It appears often on legacy drawings and equipment.
Series IIFront Release
Crimp-contact front-release option using compatible shell concepts but different service tooling and contact handling.
Series IIIRear Release
Crimp-contact rear-release option often selected when removable contacts and serviceability matter.
Cost Drivers
Contact SizeHigh
Large power contacts, heavy wire, and mixed inserts increase material, tooling, strip, crimp, and inspection time.
ClassMedium
Environmental, firewall, fluid-resistant, and hermetic classes change sourcing and assembly assumptions.
Threaded HardwareMedium
Clamps, backshells, coupling hardware, safety wire, and strain relief must match the service environment.

Common Questions
What is a MIL-DTL-5015 connector?+
It is a threaded AN-type circular connector family used for rugged power, signal, and control wiring with many shell sizes, classes, and insert arrangements.
Is MIL-DTL-5015 still current?+
MIL-DTL-5015 has been superseded in many contexts by SAE AS50151, but manufacturers, buyers, and drawings still commonly use the 5015 name.
What shell sizes does MIL-DTL-5015 cover?+
The common range is size 08 through 40, including short-shell codes such as 10SL, 14S, and 16S.
How many insert arrangements exist for MIL-DTL-5015?+
The family is commonly described with about 160 approved insert arrangements, covering layouts from single-contact power connectors to high pin-count signal layouts.
What is the difference between MIL-DTL-5015 Series I, II, and III?+
Series I is the solder-contact family, Series II is front-release crimp, and Series III is rear-release crimp.
Are MIL-DTL-5015 connectors good for high current?+
Many 5015 arrangements support larger contacts and heavier wire than miniature circular families, but current must be checked against the exact contact, wire gauge, temperature, and derating.
Why choose MIL-DTL-5015 instead of MIL-DTL-38999?+
Choose 5015 when the drawing, mating equipment, power-contact size, cost, or legacy ecosystem points to AN-type threaded connectors. Choose 38999 when density, size, weight, and severe-environment performance are the priority.
Can MiniProto build a MIL-DTL-5015 cable assembly?+
Yes. We can quote connector sourcing, heavy wire, contacts, strain relief, labels, continuity testing, and assembly labor as one harness package.
