Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFM-140-02-S-D-P-TR is determined by strict equivalence across the following critical parameters:

• Connector series (Tiger Eye™ TFM)
• Number of positions (80)
• Pitch and row spacing (0.050" / 1.27mm)
• Mounting type (Surface Mount)
• Contact type and gender (Male Pin)
• Current and voltage ratings (2.9A per Contact, 275VAC)
• Operating temperature range (-55°C ~ 125°C)
• Contact finish specifications (Gold mating surface)
• Insulation material (Liquid Crystal Polymer)
• Compliance certifications (ROHS3, UL94 V-0, MSL 1)

The identified substitute part TFM-140-02-S-D-K-TR maintains all these parameters identically, differing only in fastening mechanism designation within the same product family.

Frequently Asked Questions (FAQ)

Q: Are TFM-140-02-S-D-P-TR and TFM-140-02-S-D-K-TR electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 2.9A per contact current rating, 275VAC voltage rating, gold-plated mating contacts, and operating temperature range of -55°C to 125°C.

Q: What is the difference between these two part numbers?

A: The parts differ in fastening mechanism designation (P versus K in the part number). All other mechanical and electrical parameters remain identical.

Q: Can I substitute one part for the other on my PCB?

A: Substitution is valid when the fastening mechanism difference does not conflict with your connector housing or mating interface requirements. Verify fastening compatibility with your specific application before implementation.

Q: Are both parts compliant with RoHS and flammability standards?

A: Yes. Both TFM-140-02-S-D-P-TR and TFM-140-02-S-D-K-TR are ROHS3 compliant with UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.

Q: What is the pitch specification for these connectors?

A: Both parts feature 0.050" (1.27mm) mating pitch with 0.050" (1.27mm) row spacing in a 2-row, 80-position configuration.
