Decode Any Mil-Spec Number
Instant specification breakdown for aerospace and industrial connector workflows. Verify shell sizes, insert arrangements, and contact details before the part reaches your BOM.
Start with tracked example families
These families map directly into the curated decoder coverage and the manufacturing documentation workflow.
Instant Verification
Don't guess. Confirm that the part number in your BOM matches the physical requirements of your design.
No PDF Hunting
Stop scrolling through 500-page datasheets. Get the exact specs for your specific configuration immediately.
Supported Series
Supports tracked examples across MIL-DTL-38999, MIL-DTL-24308, M39029, MIL-5015, MIL-26482, and M12.

Why Part Number Decoding Is a Time Sink
A part number like D38999/20FJ20PN packs 7 specifications into 15 characters. Shell style. Material. Finish. Insert arrangement. Contact gender. Keying. Every character matters—and a single mistake means the wrong connector ships to your floor.
Traditionally, decoding means opening the 400-page MIL-DTL-38999 PDF, flipping to Table III, cross-referencing Table VII for insert arrangements, then double-checking the finish code in Appendix B. For one part number. Now multiply that by 30 connectors in a harness.
What This Tool Does
Paste your part number above. In milliseconds, you'll see the complete breakdown: shell size in inches, exact pin count, compatible contacts, and plating specs—all pulled directly from the standard. No PDFs. No tables. No guesswork.
Next step after verification
Once the part number is verified, the real job is carrying that exact decision into the harness workflow, BOM, and release packet.
