Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFML-120-02-L-D-TR 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)
• Pitch - mating (0.050" / 1.27mm)
• Row spacing - mating (0.050" / 1.27mm)
• Mounting type (Surface Mount)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Contact finish - mating (Gold)
• Contact finish - post (Tin)
• Insulation material (Liquid Crystal Polymer)
• Operating temperature range (-55°C ~ 125°C)
• Material flammability rating (UL94 V-0)
• RoHS compliance (ROHS3)
• Moisture sensitivity level (MSL 1)

The identified substitute part maintains all critical electrical and mechanical parameters, with the only documented difference being the inclusion of Pick and Place features in the substitute variant.

Parameter Comparison

Engineering Selection Recommendations

Both TFML-120-02-L-D-TR and TFML-120-02-L-D-K-TR are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Both parts are ROHS3 compliant and carry UL94 V-0 material flammability certification. The substitute part TFML-120-02-L-D-K-TR includes Pick and Place features, which may provide advantages in automated assembly environments. Selection between these parts should be based on assembly process requirements and inventory availability. Both parts are suitable for applications requiring surface mount 40-position headers with 1.27mm pitch spacing and operate across the -55°C to 125°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can TFML-120-02-L-D-K-TR be used as a direct replacement for TFML-120-02-L-D-TR?

A: Yes. Both parts share identical electrical and mechanical parameters including connector type, position count, pitch spacing, mounting configuration, contact finishes, insulation material, operating temperature range, and compliance certifications. The substitute part includes Pick and Place features that do not affect functional compatibility.

Q: What is the significance of the "K" designation in TFML-120-02-L-D-K-TR?

A: The "K" designation indicates the inclusion of Pick and Place features in the connector design. This does not alter the electrical or mechanical interface specifications.

Q: Are both parts available in the same packaging format?

A: Yes. Both TFML-120-02-L-D-TR and TFML-120-02-L-D-K-TR are supplied in Tape & Reel (TR) packaging.

Q: What are the critical parameters that define substitution eligibility for this connector?

A: Substitution eligibility is determined by equivalence in connector type, contact type, position count, row configuration, pitch spacing, row spacing, mounting type, shrouding design, termination method, contact finishes, insulation material, operating temperature range, flammability rating, and compliance certifications.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both parts are ROHS3 compliant, carry UL94 V-0 material flammability certification, and have MSL 1 (Unlimited) moisture sensitivity level ratings.
