Substitute Part Grouping Explanation

Substitution within the Tiger Eye™ TFC series is determined by strict electrical and mechanical compatibility. The primary substitution criterion is the maintenance of identical mating pitch (0.050"), row spacing (0.050"), number of positions (10), number of rows (2), contact type (Male Pin), shrouding configuration (Shrouded - 4 Wall), mounting type (Surface Mount), and electrical ratings (3.1A per contact, 275VAC). The substitute part TFC-105-22-F-D-A meets all these core requirements. The only variance between the main part and substitute is the insulation height dimension: TFC-105-32-F-D-A specifies 0.441" (11.20mm) while TFC-105-22-F-D-A specifies 0.366" (9.30mm). This dimensional difference reflects different board-to-board or cable clearance requirements and does not affect electrical performance or contact integrity.

Parameter Comparison

Engineering Selection Recommendations

Both TFC-105-32-F-D-A and TFC-105-22-F-D-A are active production parts from Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is determined by board-to-board or cable clearance requirements. The TFC-105-32-F-D-A with 0.441" (11.20mm) insulation height accommodates applications requiring greater vertical clearance, while the TFC-105-22-F-D-A with 0.366" (9.30mm) insulation height is suitable for space-constrained designs. Both parts maintain identical electrical performance, contact integrity, and environmental operating specifications. Inventory availability is adequate for both variants.

Frequently Asked Questions (FAQ)

Q: Can TFC-105-22-F-D-A be used as a direct replacement for TFC-105-32-F-D-A?

A: Electrical and contact compatibility is maintained. The primary design consideration is the insulation height difference of 0.075" (1.90mm). Substitution is valid only if the application PCB layout and mating connector clearance accommodate the reduced insulation height of the TFC-105-22-F-D-A.

Q: What is the significance of the insulation height parameter?

A: Insulation height determines the vertical distance from the PCB surface to the top of the connector body. This dimension affects board-to-board spacing, cable routing clearance, and overall assembly height. Selection must align with mechanical design constraints.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both parts are rated for 3.1A per contact at 275VAC across the operating temperature range of -55°C to 125°C. Contact material, finish, and mating pitch are identical.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both TFC-105-32-F-D-A and TFC-105-22-F-D-A are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant and carry UL94 V-0 flammability certification. Regulatory and environmental compliance is equivalent.
