Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFM-120-02-L-D-A-P is determined by strict equivalence across the following critical parameters:

Connector type (Header), contact type (Male Pin), number of positions (40), number of rows (2), mating pitch (0.050"/1.27mm), row spacing (0.050"/1.27mm), mounting type (Surface Mount), shrouding configuration (Shrouded - 4 Wall), termination method (Solder), current rating (2.9A per Contact), voltage rating (275VAC), operating temperature range (-55°C ~ 125°C), and material compliance (ROHS3 Compliant, UL94 V-0).

The substitute part TFM-120-02-L-D-A-K maintains identical electrical and mechanical specifications across all these parameters, confirming direct substitutability within the Tiger Eye™ TFM series.

Frequently Asked Questions (FAQ)

Q: Can TFM-120-02-L-D-A-K be used as a direct replacement for TFM-120-02-L-D-A-P?

A: Yes. Both parts are electrically and mechanically equivalent. All critical parameters including connector type, position count, pitch, mounting type, current rating, voltage rating, and operating temperature range are identical. PCB footprints and mating interface specifications are the same.

Q: Are there any differences in contact finish between these parts?

A: No. Both parts feature gold-plated mating contacts (15.0µin/0.38µm thickness) and tin-plated posts. Contact material, shape, and length specifications are identical.

Q: What determines substitutability for TFM-120-02-L-D-A-P?

A: Substitutability is determined by equivalence in connector type, contact type, position count, row configuration, mating pitch, row spacing, mounting type, shrouding, termination method, current and voltage ratings, operating temperature range, and compliance certifications. Any deviation in these parameters disqualifies a part from direct substitution.

Q: Are both parts suitable for the same environmental conditions?

A: Yes. Both parts operate across the identical temperature range of -55°C to 125°C and carry the same UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification.

Q: What is the significance of the part number suffix difference between -P and -K variants?

A: The suffix designates specific configuration or packaging variants within the TFM-120-02-L-D-A series. Despite the suffix difference, both variants maintain identical electrical and mechanical specifications for the connector header itself, confirming direct substitutability.
