Substitute Part Grouping Explanation

Substitution eligibility for the TFM-105-01-L-S is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (5)
• Pitch - mating (0.050" / 1.27mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening type (Push-Pull)
• Current rating (2.9A per Contact)
• Voltage rating (275VAC)
• Operating temperature range (-55°C ~ 125°C)
• Material compliance (ROHS3 Compliant, UL94 V-0)

The identified substitute part TFM-105-01-L-S-WT maintains full electrical and mechanical compatibility with the primary part while introducing solder retention as an additional feature. Both parts belong to the same Tiger Eye™ TFM series and share identical base product number TFM-105.

Parameter Comparison

Engineering Selection Recommendations

Both TFM-105-01-L-S and TFM-105-01-L-S-WT are active production parts with full ROHS3 compliance and UL94 V-0 material flammability certification. Selection between these parts is based on application-specific requirements:

The TFM-105-01-L-S provides standard through-hole header functionality with all specified electrical and mechanical parameters.

The TFM-105-01-L-S-WT incorporates solder retention as an additional feature, providing enhanced mechanical stability during soldering operations. This variant is suitable for applications requiring improved solder joint reliability during assembly processes.

Both parts maintain identical electrical performance, thermal ratings, and compliance certifications. The choice between them depends solely on whether solder retention capability is required for the specific assembly process.

Frequently Asked Questions (FAQ)

Q: Are TFM-105-01-L-S and TFM-105-01-L-S-WT electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 2.9A per contact current rating, 275VAC voltage rating, and operating temperature range of -55°C to 125°C. They are fully electrically interchangeable.

Q: What is the functional difference between these two parts?

A: The TFM-105-01-L-S-WT includes solder retention as an additional mechanical feature. This does not affect electrical performance but provides enhanced mechanical stability during PCB assembly and soldering operations.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Both parts are mechanically and electrically equivalent with identical pitch (0.050" / 1.27mm), position count (5), mounting type (through hole), and shrouding configuration (shrouded 4-wall). PCB footprints and mating connectors are compatible.

Q: What does the "-WT" suffix indicate?

A: The "-WT" suffix designates the inclusion of solder retention as a design feature. This is the only functional distinction between the two part numbers.

Q: Are both parts currently available?

A: Yes. TFM-105-01-L-S has 1003 pieces in stock, and TFM-105-01-L-S-WT has 781 pieces in stock, both as new original inventory.

Q: Do these parts require any special handling or storage considerations?

A: Both parts have Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
