Product Overview
Malco/Microdot 141-0000-0001 is a LEPRA/CON ultra-miniature straight jack from the screw-on series. It terminates RG-178/U or RG-196/U coaxial cable and delivers a 50 Ohm matched interface in an extremely compact footprint. TE Connectivity now manufactures this connector under alias part number 1-1532006-0. The connector satisfies NSN 5935-00-463-2520 under CAGE Code 98278, making it directly applicable to military maintenance work orders requiring exact-match qualified components. Termination is by crimp on the outer shield and solder on the center contact. The body and contacts are gold-plated brass/copper alloy. Thread size is .125-44 UNF-2A (Modified).

Applications
- Aerospace and defense cable assembly: a technician strips RG-178/U with micro-tools, solders the center contact, and crimps the ferrule over the shield using tooling specified in TE Instruction Sheet 408-8510 - this is the connector that goes into that build
- RF test bench fabrication: an engineer assembles short custom patch cables to interface high-frequency test boards with spectrum analyzers or signal generators, where a 50 Ohm matched micro-coaxial connection is required at the board port
- Military MRO fulfillment: a procurement specialist closing a maintenance work order on legacy military hardware matches NSN 5935-00-463-2520 - this part satisfies that exact requirement without triggering a substitution review
- Legacy avionics harness repair: replaces a failed straight jack in an existing wiring harness where the modified thread and cable entry dimensions must match the original build specification
Frequently Asked Questions
What mating connector does this jack accept?
This is a LEPRA/CON screw-on series jack. It mates with LEPRA/CON screw-on series plugs, such as the 142-0000-0001 and 142-0000-0002 straight plug variants. It is not compatible with SMA, SMB, MCX, or other standard miniature RF connector families, nor with LEPRA/CON slide-on or snap-on series connectors.
Is this a complete connector assembly?
The connector ships as a three-piece loose assembly: the threaded barrel body with hex flange, the center contact pin, and the outer crimp ferrule. All three pieces are required for assembly. Inspect the package contents against this list before beginning termination work.
What tooling is required to assemble this connector?
Assembly requires micro-coaxial cable stripping tools and Microdot/TE crimp tools and fixtures specific to this connector series. The applicable tooling and assembly procedure are specified in TE Instruction Sheet 408-8510 (formerly RF-ASMB-12).
Will standard UNF hardware thread onto this jack?
No. The thread is .125-44 UNF-2A Modified. Standard UNF hardware and non-modified miniature connectors will not engage correctly. Only LEPRA/CON screw-on series mating plugs with the matching modified thread should be used.
Is this connector qualified for military use?
This part satisfies NSN 5935-00-463-2520 under CAGE Code 98278. It is sourced from a government research facility as unused NOS stock. Procurement and quality teams should apply their own qualification verification process as required by their program documentation.
Gold contacts, seven self-wiping spring surfaces, a modified thread that keeps out everything that doesn't belong - this connector earned its NSN the hard way. Your cable build gets that same rigor.
