Key Parameters

Substitute Part Grouping Explanation

All substitute parts maintain identical electrical and mechanical specifications across the core parameters: 10-position, 2-row configuration; 0.050" (1.27mm) pitch; surface mount solder termination; push-pull fastening; 2.9A per contact current rating; 275VAC voltage rating; -55°C to 125°C operating temperature; UL94 V-0 flammability rating; and ROHS3 compliance.

Substitution is determined by the following key parameters:

Contact Finish Configuration: The main part TFM-105-02-SM-D uses gold mating finish with tin post finish. All substitutes maintain this same contact finish specification.

Shrouding and Insulation: All parts feature shrouded 4-wall design with black liquid crystal polymer (LCP) insulation and 0.220" (5.60mm) insulation height.

Feature Differentiation: Substitute parts are grouped by optional assembly features that do not alter electrical or mechanical compatibility:

• Board Guide (A suffix)
• Pick and Place capability (K or P suffix)
• Solder Retention (WT suffix)
• Board Lock (LC suffix)
• Combinations of the above

These features are manufacturing and assembly process enhancements that allow selection based on production requirements without affecting connector performance or interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are Active status products from Samtec Inc. and maintain ROHS3 compliance and UL94 V-0 flammability certification. Selection among these parts should be based on assembly process requirements:

For standard assembly without special handling: TFM-105-02-S-D provides baseline functionality with highest inventory availability at 2458 units.

For automated pick-and-place assembly: TFM-105-02-S-D-P (3198 units) or TFM-105-02-S-D-K (884 units) accommodate robotic placement processes.

For applications requiring enhanced solder joint reliability: TFM-105-02-S-D-WT (3503 units) or TFM-105-02-S-D-WT-K (1048 units) provide solder retention features.

For designs requiring mechanical alignment during mating: TFM-105-02-S-D-A (2993 units) includes board guide features.

For applications requiring positive mechanical locking: TFM-105-02-S-D-LC (1749 units) provides board lock capability.

All parts share identical electrical performance, contact ratings, temperature range, and compliance certifications. Selection is driven by manufacturing process compatibility and mechanical assembly requirements, not electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts electrically interchangeable with TFM-105-02-SM-D?

A: Yes. All substitute parts maintain identical electrical specifications: 10 positions, 2 rows, 0.050" (1.27mm) pitch, 2.9A per contact current rating, and 275VAC voltage rating. The feature differences (Board Guide, Pick and Place, Solder Retention, Board Lock) are manufacturing and assembly enhancements that do not affect electrical performance or signal integrity.

Q: What is the difference between Pick and Place (K or P suffix) variants?

A: Both K and P suffixes indicate pick-and-place compatibility for automated assembly equipment. The designation allows robotic placement systems to handle the connector during manufacturing. Electrical and mechanical performance remain identical.

Q: Can I substitute TFM-105-02-SM-D with TFM-105-02-S-D?

A: Yes. Both parts are functionally equivalent. The primary difference is in the part numbering scheme. TFM-105-02-S-D is available in higher inventory (2458 units versus 1105 units) and provides the same electrical and mechanical specifications.

Q: What does Solder Retention (WT suffix) provide?

A: Solder Retention is a manufacturing feature that improves solder joint stability during reflow processes. It does not alter the connector's electrical characteristics or mating interface. Selection depends on assembly process requirements and PCB design considerations.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed parts, including the main part TFM-105-02-SM-D and all substitutes, are ROHS3 compliant with UL94 V-0 flammability rating and Moisture Sensitivity Level 1 (Unlimited).

Q: Can I mix different variants in the same design?

A: Yes. Since all variants maintain identical electrical and mechanical specifications across the mating interface, they can be used interchangeably in the same circuit design. Feature differences are assembly-process specific and do not affect connector compatibility or performance.
