Samtec TFM series parts (TFM-135-12-S-D-A, TFM-135-22-S-D-LC, TFM-135-32-S-D-A, TFM-135-12-S-D-LC) are direct substitutes within the same product family with variations in insulation height and mounting features. The TE Connectivity part 5-104693-7 is a cross-manufacturer equivalent with compatible electrical and mechanical specifications, though with minor differences in contact geometry and current rating.

Parameter Comparison

Engineering Selection Recommendations

Samtec Tiger Eye™ TFM Series Substitutes (TFM-135-12-S-D-A, TFM-135-22-S-D-LC, TFM-135-32-S-D-A, TFM-135-12-S-D-LC):

These parts maintain full electrical and thermal compatibility with the TFM-135-22-S-D. Selection among these variants depends on PCB layout constraints and mechanical mounting requirements:

• TFM-135-12-S-D-A and TFM-135-12-S-D-LC: Reduced insulation height (0.290") for space-constrained applications. Board Guide feature (TFM-135-12-S-D-A) or Board Lock feature (TFM-135-12-S-D-LC) provides mechanical alignment options.

• TFM-135-22-S-D-LC: Identical insulation height (0.360") to the main part with Board Lock feature for enhanced mechanical retention.

• TFM-135-32-S-D-A: Increased insulation height (0.435") for applications requiring additional clearance. Includes Board Guide feature.

All Samtec variants are ROHS3 compliant, rated for 2.9A per contact at 275VAC, and operate across -55°C to 125°C. Product status is Active for all variants.

TE Connectivity 5-104693-7 (Cross-Manufacturer Equivalent):

This part provides functional equivalence with notable electrical differences. The 0.5A per contact rating is significantly lower than the TFM series (2.9A), making it unsuitable for high-current applications. Operating temperature range (-65°C to 105°C) is narrower at the upper limit. Contact geometry differs (circular vs. square), and voltage rating is not specified. This part is suitable only for low-current, general-purpose applications where the reduced current capacity is acceptable. ROHS3 compliance and UL94 V-0 flammability rating are maintained.

Selection Criteria:

• For direct replacement with identical electrical performance: Select TFM-135-22-S-D-LC (Board Lock variant with same insulation height).
• For space-constrained designs: Select TFM-135-12-S-D-A or TFM-135-12-S-D-LC (reduced height variants).
• For applications requiring additional clearance: Select TFM-135-32-S-D-A (increased height variant).
• For low-current applications only: 5-104693-7 is acceptable if current requirements do not exceed 0.5A per contact.

Frequently Asked Questions (FAQ)

Q: Can TFM-135-12-S-D-A be used as a direct replacement for TFM-135-22-S-D?

A: Yes, with PCB layout verification. The TFM-135-12-S-D-A has identical electrical ratings (2.9A per contact, 275VAC, -55°C to 125°C) and connector pitch (0.050" / 1.27mm). The primary difference is insulation height: 0.290" versus 0.360". This reduced height may affect mating connector clearance and should be verified against your specific PCB layout and mating connector specifications.

Q: What is the difference between Board Guide and Board Lock features?

A: Board Guide (present on TFM-135-12-S-D-A and TFM-135-32-S-D-A) provides mechanical alignment during connector mating. Board Lock (present on TFM-135-22-S-D-LC and TFM-135-12-S-D-LC) provides enhanced mechanical retention after mating. Selection depends on your application's mechanical stability requirements and PCB design.

Q: Is the TE Connectivity 5-104693-7 suitable for high-current applications?

A: No. The 5-104693-7 is rated for 0.5A per contact, compared to 2.9A for all Samtec TFM variants. Use this part only in applications where current per contact does not exceed 0.5A. For higher current requirements, select a Samtec TFM series part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (TFM-135-12-S-D-A, TFM-135-22-S-D-LC, TFM-135-32-S-D-A, TFM-135-12-S-D-LC, and 5-104693-7) are ROHS3 compliant with UL94 V-0 flammability rating.

Q: What is the operating temperature range for each substitute?

A: Samtec TFM series parts (TFM-135-12-S-D-A, TFM-135-22-S-D-LC, TFM-135-32-S-D-A, TFM-135-12-S-D-LC) operate from -55°C to 125°C. The TE Connectivity 5-104693-7 operates from -65°C to 105°C, with a narrower upper temperature limit.

Q: Can I mix different insulation heights in the same assembly?

A: Mixing insulation heights (0.290", 0.360", 0.435") is not recommended without mechanical analysis. Different heights may affect mating connector alignment and overall assembly stack-up. Maintain consistent insulation height across all connectors in a single mating pair.

Q: Which substitute has the highest inventory availability?

A: The TE Connectivity 5-104693-7 has the highest inventory at 1201 units. Among Samtec TFM variants, TFM-135-22-S-D-LC has the highest inventory at 1039 units.
