Parameter Comparison

Engineering Selection Recommendations

All three parts—TFML-110-02-SM-D-A-P-TR, TFML-110-02-S-D-A-K-TR, and TFML-110-02-S-D-A-P-TR—are active products from Samtec Inc. within the Tiger Eye™ TFML series. Each part maintains ROHS3 compliance and UL94 V-0 material flammability rating, meeting regulatory requirements for industrial and commercial applications. The parts are functionally equivalent across all specified electrical and mechanical parameters, including operating temperature range of -55°C to 125°C and moisture sensitivity level 1 (unlimited shelf life). Selection among these parts may be based on inventory availability or specific procurement requirements, as all three are qualified for direct substitution in applications requiring 20-position, 1.27mm pitch surface mount headers with shrouded 4-wall configuration.

Frequently Asked Questions (FAQ)

Q: Are TFML-110-02-S-D-A-K-TR and TFML-110-02-S-D-A-P-TR direct substitutes for TFML-110-02-SM-D-A-P-TR?

A: Yes. All three parts share identical electrical and mechanical specifications including connector type, position count, pitch, mounting method, contact materials, and operating temperature range. The differences in part number designations do not affect functional compatibility.

Q: What determines substitutability for this connector family?

A: Substitutability is determined by equivalence in the following parameters: number of positions (20), number of rows (2), mating pitch (0.050"/1.27mm), row spacing (0.050"/1.27mm), mounting type (surface mount), connector type (header), contact type (male pin), shrouding configuration (shrouded 4-wall), termination method (solder), fastening type (friction lock), contact materials (phosphor bronze), insulation material (LCP), and operating temperature range (-55°C to 125°C).

Q: Do these parts require different PCB footprints?

A: No. All three parts maintain identical mechanical dimensions including insulation height (0.220"/5.60mm), contact length for mating (0.134"/3.39mm), and contact shape (square). PCB footprints are interchangeable.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts are ROHS3 compliant, carry UL94 V-0 material flammability rating, and have moisture sensitivity level 1 (unlimited). Compliance status is identical across all substitute options.

Q: What is the significance of the part number variations?

A: The part number variations reflect internal Samtec configuration codes. The specific codes (SM vs. S, K vs. P) indicate connector design variants, but all variants listed maintain full electrical and mechanical compatibility for this 20-position, 1.27mm pitch application.

Q: Can these connectors be used interchangeably in mating applications?

A: Yes. The mating interface specifications—pitch, row spacing, contact length, and contact finish—are identical across all three parts. Mating connectors designed for one part will function with any of the three substitute parts.
