Engineering Selection Recommendations

All listed substitute parts are active products with full RoHS compliance and UL94 V-0 flammability ratings, making them suitable replacements for the obsolete M20-9743442.

The Amphenol ICC (FCI) BERGSTIK® series parts offer extended operating temperature range (-65°C ~ 130°C) compared to the original specification (-40°C ~ 105°C), providing enhanced thermal performance for demanding applications. These parts are available in both bag and bulk packaging options.

The Sullins Connector Solutions PRPC034DBAN-M71RC maintains the original operating temperature range (-40°C ~ 105°C) and offers compatibility with applications requiring identical thermal specifications. This part is supplied in bulk packaging.

Minor variations in contact length post (0.100", 0.120", or 0.118") and insulation height (0.190", 0.197", or 0.200") exist across substitute options. These dimensional differences are within acceptable tolerances for standard through-hole PCB applications and do not affect electrical performance or mating compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the M20-9743442?

A: Yes. All listed substitute parts maintain the critical mating parameters: 0.100" (2.54mm) pitch, 68 positions, 2 rows, and 0.100" row spacing. They are mechanically and electrically compatible for through-hole, right-angle board-to-board or cable applications.

Q: What is the difference between the Amphenol ICC parts with different suffixes (103, 104, 403, 404, 803, 804)?

A: The differences are in contact post length and contact finish specifications. Parts ending in 03 or 803 have 0.100" (2.54mm) post length, while 04 or 804 have 0.120" (3.05mm) post length. Contact finish varies between gold (GXT™ or standard) and tin. All maintain the same mating pitch and position count.

Q: Does the extended operating temperature range of the Amphenol parts affect compatibility?

A: No. The extended range (-65°C ~ 130°C) is a superset of the original specification (-40°C ~ 105°C). Parts rated for wider temperature ranges are fully compatible with applications designed for the original temperature limits.

Q: What packaging options are available?

A: Amphenol ICC parts are supplied in bag or bulk packaging. Sullins parts are supplied in bulk packaging. Packaging selection does not affect electrical or mechanical performance.

Q: Are there compliance differences between substitute options?

A: All parts are RoHS compliant. Amphenol ICC parts are RoHS Compliant, while the original M20-9743442 and Sullins PRPC034DBAN-M71RC are ROHS3 Compliant. Both compliance levels meet current regulatory requirements.
