TFML-110-02-SM-D-P-TR Equivalent & Substitute Parts

Part Overview

The TFML-110-02-SM-D-P-TR is a surface mount rectangular connector header manufactured by Samtec Inc. as part of the Tiger Eye™ TFML series. This 20-position connector operates in the -55°C to 125°C temperature range and is designed for board-to-board or cable applications with friction lock fastening. The part is active in production with ROHS3 compliance and UL94 V-0 flammability rating. Equivalent and substitute parts are identified based on matching electrical and mechanical specifications within the TFML-110 base product family.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the TFML-110 family is determined by the following critical parameters: connector type (header), contact type (male pin), number of positions (20), number of rows (2), mating pitch (0.050"/1.27mm), row spacing (0.050"/1.27mm), mounting type (surface mount), termination method (solder), fastening type (friction lock), contact length for mating (0.134"/3.39mm), insulation height (0.220"/5.60mm), contact finish on mating surface (gold), contact material (phosphor bronze), insulation material (LCP), operating temperature range (-55°C to 125°C), and flammability rating (UL94 V-0).

The substitute parts TFML-110-02-S-D-K-TR and TFML-110-02-S-D-P-TR maintain all these critical parameters. The primary difference between the main part and substitutes is the contact length on the post side. The main part TFML-110-02-SM-D-P-TR has an unspecified post contact length, while TFML-110-02-S-D-P-TR specifies 0.075" (1.91mm). Both substitute parts are functionally equivalent for applications requiring the specified mating characteristics and environmental performance.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TFML-110-02-SM-D-P-TR, TFML-110-02-S-D-K-TR, and TFML-110-02-S-D-P-TR—are active production parts from Samtec Inc. with identical compliance certifications: ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 (unlimited moisture sensitivity level). All parts are suitable for applications requiring the specified electrical and mechanical characteristics within the -55°C to 125°C operating temperature range.

Selection between these parts should be based on specific application requirements regarding post contact length and availability. TFML-110-02-S-D-P-TR provides a defined post contact length of 0.075" (1.91mm), which may be required for specific PCB assembly or mating interface specifications. The other variants are suitable where post contact length is not a critical design parameter.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for TFML-110-02-SM-D-P-TR?

A: Substitution is valid when the following parameters match: connector type (header), contact type (male pin), number of positions (20), number of rows (2), mating pitch (0.050"/1.27mm), row spacing (0.050"/1.27mm), mounting type (surface mount), termination (solder), fastening type (friction lock), contact length for mating (0.134"/3.39mm), insulation height (0.220"/5.60mm), contact finish on mating surface (gold), contact material (phosphor bronze), insulation material (LCP), operating temperature range (-55°C to 125°C), and flammability rating (UL94 V-0).

Q: Are TFML-110-02-S-D-K-TR and TFML-110-02-S-D-P-TR interchangeable with TFML-110-02-SM-D-P-TR?

A: Yes. Both substitute parts maintain all critical electrical and mechanical parameters. The difference in post contact length specification does not affect interchangeability for standard board-to-board or cable applications using the mating interface.

Q: What is the significance of the post contact length parameter?

A: Post contact length defines the solder tail length on the PCB side. TFML-110-02-S-D-P-TR specifies 0.075" (1.91mm), while the main part and TFML-110-02-S-D-K-TR do not specify this value. Applications with specific PCB thickness or solder joint requirements may require the defined post length specification.

Q: Are all three parts available in the same packaging format?

A: Yes. All three parts are supplied in Tape & Reel (TR) packaging, suitable for automated pick-and-place assembly processes.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, carry UL94 V-0 flammability rating, and have MSL 1 (unlimited) moisture sensitivity level. All are active production parts from Samtec Inc.
