Parameter Comparison

Engineering Selection Recommendations

Both TFM-110-22-SM-D-A-P and TFM-110-12-S-D-A-K are active production parts from Samtec Inc. with identical ROHS3 compliance and UL94 V-0 flammability ratings. Selection between these parts depends on the available board space and PCB layout constraints. The TFM-110-22-SM-D-A-P with 0.360" (9.14mm) insulation height is suitable for applications requiring greater clearance above the PCB. The TFM-110-12-S-D-A-K with 0.290" (7.37mm) insulation height accommodates space-constrained designs. Both parts maintain identical electrical performance, contact configuration, and environmental operating specifications.

Frequently Asked Questions (FAQ)

Q: Can TFM-110-12-S-D-A-K be used as a direct replacement for TFM-110-22-SM-D-A-P?

A: Yes, with consideration for insulation height. The TFM-110-12-S-D-A-K has a lower insulation height of 0.290" (7.37mm) compared to 0.360" (9.14mm) on the TFM-110-22-SM-D-A-P. All electrical parameters, contact configuration, and compliance certifications are identical. Verify that the reduced height accommodates your PCB layout and component clearance requirements.

Q: Are the contact specifications identical between these parts?

A: Yes. Both parts feature 20 male pin contacts in a 2-row configuration with 0.050" (1.27mm) pitch, square contact shape, gold mating finish at 30.0µin (0.76µm) thickness, and phosphor bronze contact material. Current and voltage ratings are identical at 2.9A per contact and 275VAC respectively.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TFM-110-22-SM-D-A-P and TFM-110-12-S-D-A-K are ROHS3 compliant with UL94 V-0 flammability rating and Moisture Sensitivity Level 1 (Unlimited). Both are active production parts from Samtec Inc.

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

A: The primary difference is insulation height. TFM-110-22-SM-D-A-P has 0.360" (9.14mm) insulation height, while TFM-110-12-S-D-A-K has 0.290" (7.37mm). This difference accommodates different PCB layout and clearance requirements while maintaining all other specifications.

Q: Are these parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -55°C to 125°C, making them interchangeable from a thermal performance perspective.
