Engineering Selection Recommendations

Both the 75869-233LF and 3-1761603-0 are active production parts with RoHS compliance and UL94 V-0 flammability certification. Selection between these parts should be based on the following considerations:

The 75869-233LF features tin plating on mating contacts and glass-filled thermoplastic insulation. The 3-1761603-0 provides gold plating on mating contacts with PBT insulation material and specified electrical ratings (1A per contact, 250VAC operating range -65°C to 105°C). The gold finish on the TE Connectivity part provides enhanced corrosion resistance compared to tin plating. The PBT insulation material in the substitute part offers superior chemical resistance and dimensional stability relative to glass-filled thermoplastic.

Physical dimensions vary slightly between the two parts, with the TE Connectivity connector featuring a lower insulation height (0.350" versus 0.377") and shorter post length (0.102" versus 0.120"), while mating contact length is marginally longer (0.240" versus 0.236").

Frequently Asked Questions (FAQ)

Q: Can 3-1761603-0 be used as a direct replacement for 75869-233LF?

A: Yes, the 3-1761603-0 qualifies as a functional equivalent based on matching connector type, position count, pitch, mounting method, and shrouding configuration. Physical dimension variations are minor and should be verified against specific PCB layout requirements.

Q: What are the key differences between these two connectors?

A: Primary differences include contact finish (tin versus gold), insulation material (glass-filled thermoplastic versus PBT), and specified electrical ratings. The TE Connectivity part provides documented operating temperature range and current/voltage specifications, while the Amphenol part does not specify these parameters.

Q: Are there any compatibility concerns with the dimensional differences?

A: The insulation height difference (0.377" versus 0.350") and post length variation (0.120" versus 0.102") should be evaluated against PCB design specifications, mating connector depth requirements, and solder joint clearance. The mating contact length difference (0.236" versus 0.240") is negligible for standard applications.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS Compliant with UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity level. Both carry EAR99 ECCN classification and identical HTSUS codes.

Q: Which part should be selected for high-reliability applications?

A: Selection should be based on specific application requirements. The TE Connectivity 3-1761603-0 provides documented electrical ratings and operating temperature specifications suitable for applications requiring defined performance parameters. The gold contact finish offers enhanced durability in environments with potential corrosion exposure.
