Substitute Part Grouping Explanation

The TFM-107-23-S-D has one identified substitute: TFM-107-03-S-D-WT. Both parts share the same base product number (TFM-107) and maintain electrical and mechanical compatibility through identical specifications in the following critical parameters:

• Number of positions: 14
• Number of rows: 2
• Pitch - mating: 0.050" (1.27mm)
• Row spacing - mating: 0.050" (1.27mm)
• Contact type: Male Pin
• Connector type: Header
• Mounting type: Through Hole
• Termination: Solder
• Current rating: 2.9A per Contact
• Voltage rating: 275VAC
• Operating temperature: -55°C ~ 125°C
• Contact finish - mating: Gold
• Contact material: Phosphor Bronze
• Insulation material: Liquid Crystal Polymer (LCP)
• Material flammability rating: UL94 V-0

The substitute part differs in packaging format (Tube vs. standard packaging) and insulation height, with the substitute featuring solder retention and a lower insulation height of 0.220" (5.60mm) compared to 0.360" (9.14mm) on the main part.

Parameter Comparison

Engineering Selection Recommendations

Both TFM-107-23-S-D and TFM-107-03-S-D-WT are active products from Samtec Inc. with full ROHS3 compliance and identical electrical performance specifications. Selection between these parts should be based on the following factors:

The TFM-107-23-S-D features a standard insulation height of 0.360" (9.14mm) and is supplied in standard packaging. The TFM-107-03-S-D-WT provides the same electrical and mechanical interface with a reduced insulation height of 0.220" (5.60mm), includes solder retention features, and is supplied in tube packaging. The reduced insulation height of the substitute part may be advantageous in space-constrained applications where board-to-board clearance is limited.

Both parts maintain identical current and voltage ratings, operating temperature ranges, and contact materials. The choice between these parts depends on physical space requirements and packaging preferences rather than electrical performance.

Frequently Asked Questions (FAQ)

Q: Can TFM-107-03-S-D-WT be used as a direct replacement for TFM-107-23-S-D?

A: Yes, from an electrical and mating interface perspective. Both parts have identical pitch, row spacing, number of positions, contact type, and electrical ratings. The primary difference is the insulation height: 0.220" (5.60mm) for the substitute versus 0.360" (9.14mm) for the main part. Verify that the reduced insulation height does not conflict with your board layout or clearance requirements.

Q: What is the significance of the insulation height difference?

A: Insulation height determines the vertical clearance between the connector body and the PCB surface. The TFM-107-03-S-D-WT has a lower profile, which may be beneficial in applications with space constraints but requires verification that the reduced height does not interfere with adjacent components or board features.

Q: Does the solder retention feature on TFM-107-03-S-D-WT affect compatibility?

A: No. Solder retention is a manufacturing feature that improves solder joint reliability during assembly. It does not affect electrical performance or mechanical compatibility with mating connectors.

Q: Are there packaging differences between these parts?

A: Yes. TFM-107-23-S-D uses standard packaging, while TFM-107-03-S-D-WT is supplied in tube packaging. This affects handling and storage but does not impact electrical or mechanical performance.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant and carry the same ECCN (EAR99) and HTSUS classifications. Both meet UL94 V-0 flammability requirements and operate across the same temperature range (-55°C ~ 125°C).
