For applications requiring extended operating temperature range (-65°C ~ 130°C), select from Amphenol ICC BERGSTIK® series parts: 10076801-406T18LF, 10076801-406-18LF, 68481-118HLF, 68691-118HLF, or 78548-118.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0010977185 directly replace the TE Connectivity 104433-9?

A: The Molex 0010977185 matches all primary mechanical and electrical parameters: 18 positions, 2 rows, 0.100" pitch, through-hole mounting, push-pull fastening, and UL94 V-0 flammability rating. However, it features tin-finished copper alloy contacts versus the original gold-finished copper alloy contacts. Operating temperature and voltage ratings are not specified for the Molex part. Compatibility depends on application requirements for contact finish and temperature range.

Q: What is the difference between the Amphenol 10076801-406-18LF and 10076801-406T18LF?

A: These parts are electrically and mechanically identical. The primary difference is packaging: 10076801-406-18LF is supplied in bag packaging, while 10076801-406T18LF is supplied in tube packaging. Both are RoHS Compliant, active products with operating temperature -65°C ~ 130°C and 3A per contact current rating.

Q: Why do some substitute parts have unspecified operating temperature ranges?

A: Operating temperature specifications are provided only when explicitly documented by the manufacturer. Parts with unspecified operating temperature ranges may still be suitable for applications within the original part's temperature range (-65°C ~ 105°C), but this cannot be confirmed from available data. Contact the manufacturer for clarification when operating temperature is critical to application performance.

Q: Are the BERGSTIK® and BERGSTIK® II series parts interchangeable?

A: BERGSTIK® and BERGSTIK® II series parts share the same 18-position, 2-row, 0.100" pitch configuration and are mechanically compatible. However, they differ in contact length, insulation height, and contact finish specifications. Verify specific contact length and post length requirements before substitution, as these dimensions affect mating depth and board layout.

Q: What is the significance of kinked pin termination in parts like 78548-218H and 78548-218HLF?

A: Kinked pin termination provides mechanical retention during assembly and soldering. Parts with kinked pin termination (78548-218H, 78548-218HLF) offer improved stability during wave soldering compared to straight pin designs. This termination style is suitable for high-volume manufacturing processes where mechanical retention during soldering is beneficial.

Q: Which substitute part offers the best RoHS compliance status?

A: The Molex 0010977185 carries ROHS3 Compliant status, representing the most current RoHS certification. Amphenol ICC parts 10076801-406T18LF, 10076801-406-18LF, 68691-118HLF, 78548-218HLF, and Hirose A1-18PA-2.54DSA(71) are RoHS Compliant. Parts 78548-218H and 78548-218 are RoHS non-compliant. For new designs, select ROHS3 Compliant or RoHS Compliant parts.

Q: Can the Hirose A1-18PA-2.54DSA(71) be used in applications requiring the original -65°C ~ 105°C temperature range?

A: The Hirose part operates within -55°C ~ 85°C, which does not fully cover the original -65°C ~ 105°C range. It is not suitable for applications requiring operation below -55°C or above 85°C. For full temperature range compatibility, select Amphenol ICC BERGSTIK® series parts rated -65°C ~ 130°C.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in the following packaging formats: Bulk (Molex 0010977185, Amphenol 78548-218H, 78548-218HLF), Bag (Amphenol 10076801-406-18LF, 68481-118HLF, 68691-118HLF), Tube (Amphenol 10076801-406T18LF), and Tray (Hirose A1-18PA-2.54DSA(71)). Select packaging based on inventory management and assembly process requirements.

Q: Are all substitute parts rated for 3A current?

A: Current ratings are specified as 3A or 3A per contact for most substitute parts. Molex 0010977185, Amphenol 78548-218H, and 78548-218 do not specify current ratings. For applications requiring confirmed 3A rating, select from: 10076801-406-18LF, 10076801-406T18LF, 68481-118HLF, 68691-118HLF, or A1-18PA-2.54DSA(71).
