Engineering Selection Recommendations

Both the HTMS-140-02-S-D and 6-103916-6 are active products with ROHS3 compliance and UL94 V-0 flammability certification. The primary distinction between these parts lies in the operating temperature range and insulation material composition. The HTMS-140-02-S-D supports -55°C to 125°C operation with Liquid Crystal Polymer insulation, while the 6-103916-6 operates from -65°C to 105°C with thermoplastic insulation. Selection between these equivalents should be based on the specific thermal requirements of the application. Both parts maintain identical electrical and mechanical interface specifications, including pitch, row spacing, contact configuration, and fastening mechanism, ensuring functional interchangeability within their respective temperature operating windows.

Frequently Asked Questions (FAQ)

Q: What makes 6-103916-6 a suitable substitute for HTMS-140-02-S-D?

A: The 6-103916-6 meets all critical substitution parameters: identical 80-position, 2-row configuration with 0.050" pitch spacing, through-hole solder termination, push-pull fastening, unshrouded design, and square contact geometry. Both parts carry ROHS3 compliance and UL94 V-0 flammability ratings with MSL 1 moisture sensitivity.

Q: Are there differences in operating temperature between these parts?

A: Yes. The HTMS-140-02-S-D operates from -55°C to 125°C, while the 6-103916-6 operates from -65°C to 105°C. Applications requiring operation above 105°C should use the HTMS-140-02-S-D. Applications requiring operation below -55°C should use the 6-103916-6.
