Substitute Part Grouping Explanation

The TFML-125-02-SM-D-LC has one identified substitute within the Tiger Eye™ TFML series: TFML-125-02-S-D-LC. Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (50 positions, 2 rows)
• Mating pitch and row spacing (0.050" / 1.27mm)
• Mounting technology (Surface Mount)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Friction Lock)
• Contact material and finish specifications (Phosphor Bronze, Gold mating finish)
• Insulation material (Liquid Crystal Polymer)
• Operating temperature range (-55°C ~ 125°C)
• Regulatory compliance (ROHS3, UL94 V-0)

The substitute part maintains identical electrical and mechanical specifications across all provided parameters, ensuring direct interchangeability in applications requiring the TFML-125-02-SM-D-LC.

Parameter Comparison

Engineering Selection Recommendations

Both the TFML-125-02-SM-D-LC and TFML-125-02-S-D-LC are active production parts within the Tiger Eye™ TFML series. Both parts maintain full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is based on inventory availability and supply chain considerations rather than technical performance differences. The TFML-125-02-S-D-LC currently has higher inventory availability at 1418 units compared to 1165 units for the TFML-125-02-SM-D-LC. Both parts are suitable for applications requiring surface mount 50-position headers with 1.27mm pitch in the -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Are TFML-125-02-SM-D-LC and TFML-125-02-S-D-LC directly interchangeable?

A: Yes. Both parts share identical electrical and mechanical specifications across all critical parameters including position count, pitch, mounting type, contact materials, and operating temperature range. They are direct substitutes within the Tiger Eye™ TFML series.

Q: What are the key parameters that determine substitution eligibility for this connector?
