Key Parameters

Substitute Part Grouping Explanation

Substitution for the TFM-107-02-L-S is based on strict equivalence across the following critical parameters:

• Connector series and manufacturer (Samtec Inc., Tiger Eye™ TFM)
• Number of positions (7)
• Pitch specification (0.050" / 1.27mm)
• Mounting technology (Surface Mount)
• Connector type and contact configuration (Header, Male Pin)
• Shrouding design (Shrouded - 4 Wall)
• Fastening mechanism (Push-Pull)
• Electrical ratings (2.9A per Contact, 275VAC)
• Operating temperature range (-55°C ~ 125°C)
• Compliance certifications (ROHS3 Compliant, UL94 V-0)

Parts meeting all these criteria are classified as direct substitutes. Variations in secondary features such as solder retention characteristics do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both TFM-107-02-L-S and TFM-107-02-L-S-WT are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on application-specific requirements:

The TFM-107-02-L-S-WT variant includes solder retention features, which may be beneficial in applications requiring enhanced manufacturing robustness during reflow soldering processes. The standard TFM-107-02-L-S remains suitable for applications where solder retention is not a design requirement.

Both parts maintain full ROHS3 compliance, UL94 V-0 flammability rating, and identical electrical performance across the specified operating temperature range. Inventory availability differs between variants, with TFM-107-02-L-S-WT currently showing higher stock levels (1703 pcs vs. 1016 pcs).

Frequently Asked Questions (FAQ)

Q: Are TFM-107-02-L-S and TFM-107-02-L-S-WT electrically interchangeable?

A: Yes. Both parts share identical electrical ratings (2.9A per contact, 275VAC), operating temperature range (-55°C ~ 125°C), and contact specifications. They are direct electrical substitutes.

Q: What is the difference between these two part numbers?

A: The primary difference is the inclusion of solder retention features in the TFM-107-02-L-S-WT variant. This feature enhances solder joint stability during manufacturing but does not affect electrical or mechanical performance in the assembled connector.

Q: Can I use TFM-107-02-L-S-WT as a drop-in replacement for TFM-107-02-L-S?

A: Yes. The TFM-107-02-L-S-WT is a direct substitute. All mechanical dimensions, pitch, mounting footprint, and electrical characteristics are identical. No PCB redesign is required.

Q: Are both parts RoHS compliant?

A: Yes. Both TFM-107-02-L-S and TFM-107-02-L-S-WT are ROHS3 compliant and carry UL94 V-0 flammability certification.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control requirements.

Q: Which part should I select if solder retention is important for my application?

A: Select TFM-107-02-L-S-WT. This variant includes solder retention features designed to maintain joint integrity during reflow soldering and thermal cycling.
