Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TFM-110-02-L-S are identified based on strict electrical and mechanical parameter equivalence within the Tiger Eye™ TFM series. All substitute parts maintain identical specifications for the following critical parameters:

• Connector type, contact type, and gender (Header, Male Pin)
• Number of positions and rows (10 positions, 1 row)
• Pitch and mating dimensions (0.050" / 1.27mm)
• Mounting method (Surface Mount)
• Shrouding configuration (Shrouded - 4 Wall)
• Electrical ratings (2.9A per contact, 275VAC)
• Operating temperature range (-55°C ~ 125°C)
• Contact finish and material (Gold mating surface, Phosphor Bronze)
• Insulation material and flammability (LCP, UL94 V-0)
• Compliance certifications (ROHS3, MSL 1)

Substitutes differ only in optional features (Board Guide, Solder Retention) that do not affect core electrical or mechanical compatibility. These feature variations allow selection based on specific assembly or application requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TFM-110-02-L-S, TFM-110-02-L-S-A, and TFM-110-02-L-S-WT—are Active status products from Samtec Inc. and are fully interchangeable from an electrical and mechanical standpoint. Selection between these parts should be based on assembly process requirements and application-specific features:

TFM-110-02-L-S is the base configuration without additional features, suitable for standard board-to-board applications where no specialized assembly aids are required.

TFM-110-02-L-S-A includes a Board Guide feature, which provides alignment assistance during mating operations. This variant is beneficial in applications requiring precise connector positioning or where manual assembly accuracy is critical.

TFM-110-02-L-S-WT includes Solder Retention, which enhances solder joint stability during reflow and thermal cycling. This variant is recommended for applications subject to vibration, thermal stress, or high-reliability requirements.

All parts comply with ROHS3 and carry UL94 V-0 flammability certification, supporting use in regulated and safety-critical applications. Moisture Sensitivity Level 1 (Unlimited) indicates no special storage or handling precautions are required.

Frequently Asked Questions (FAQ)

Q: Are TFM-110-02-L-S, TFM-110-02-L-S-A, and TFM-110-02-L-S-WT electrically interchangeable?

A: Yes. All three parts carry identical electrical ratings (2.9A per contact, 275VAC), operating temperature range (-55°C ~ 125°C), contact materials, and finishes. They are fully interchangeable in electrical function.

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

A: The base part TFM-110-02-L-S has no additional features. TFM-110-02-L-S-A adds a Board Guide for mating alignment. TFM-110-02-L-S-WT adds Solder Retention for enhanced joint stability. All other specifications remain identical.

Q: Can I substitute TFM-110-02-L-S-A for TFM-110-02-L-S in an existing design?

A: Yes. The Board Guide feature does not affect electrical performance or mechanical compatibility. The connector will function identically in the application.

Q: Which variant should I use for high-vibration applications?

A: TFM-110-02-L-S-WT is recommended for high-vibration environments due to its Solder Retention feature, which improves joint durability under mechanical stress.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts are ROHS3 Compliant and suitable for applications requiring RoHS certification.

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

A: All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control or baking procedures are required during storage or handling.

Q: Can these connectors be used in high-temperature applications?

A: Yes. All three parts operate across the temperature range -55°C ~ 125°C and are rated UL94 V-0 for flammability, supporting use in demanding thermal environments.
