Substitute Part Grouping Explanation

Substitution eligibility for the TFC-145-02-L-D is determined by strict equivalence across the following critical parameters:

• Connector Type & Series: Must be Header type from Tiger Eye™ TFC series
• Position Configuration: 90 positions in 2-row arrangement
• Pitch Specifications: 0.050" (1.27mm) mating pitch and 0.050" (1.27mm) row spacing
• Electrical Ratings: 3.1A per contact and 275VAC voltage rating
• Contact Specifications: Male pin contact type with square contact shape
• Mounting & Termination: Surface mount with solder termination
• Material & Compliance: Phosphor bronze contacts with gold mating finish, LCP insulation, UL94 V-0 flammability rating, ROHS3 compliance

The substitute part TFC-145-02-L-D-A maintains all critical electrical and mechanical parameters while introducing a board guide feature. This addition does not alter the core substitution relationship.

Parameter Comparison

Engineering Selection Recommendations

Both TFC-145-02-L-D and TFC-145-02-L-D-A are active products with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on application-specific requirements:

The TFC-145-02-L-D-A includes a board guide feature not present in the TFC-145-02-L-D. This feature may provide mechanical alignment benefits in applications requiring precise connector positioning during assembly or mating operations. Both parts maintain identical electrical performance, current capacity, voltage ratings, and operating temperature ranges.

Inventory availability favors TFC-145-02-L-D-A with 1164 units in stock compared to 1018 units for TFC-145-02-L-D. Both parts are supplied in tube packaging and are suitable for surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can TFC-145-02-L-D-A be used as a direct replacement for TFC-145-02-L-D?

A: Yes. Both parts share identical electrical ratings (3.1A per contact, 275VAC), mechanical pitch specifications (0.050" mating and row spacing), contact configuration (90 positions, 2 rows, male pins), and material properties. The board guide feature in TFC-145-02-L-D-A is an addition that does not compromise compatibility.

Q: What is the significance of the board guide feature in TFC-145-02-L-D-A?

A: The board guide is a mechanical feature that aids in connector alignment during assembly and mating. It does not alter electrical performance or contact specifications. Its inclusion depends on application requirements for mechanical guidance.

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

A: Yes. Both TFC-145-02-L-D and TFC-145-02-L-D-A operate across -55°C to 125°C, with identical contact materials (phosphor bronze) and insulation (LCP).

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant with UL94 V-0 flammability rating, MSL 1 (unlimited moisture sensitivity level), and identical ECCN and HTSUS classifications.

Q: What packaging format is used for these connectors?

A: Both parts are supplied in tube packaging, suitable for automated surface mount assembly processes.

Q: Are there any differences in contact finish between these parts?

A: No. Both parts feature gold mating contact finish (10.0µin / 0.25µm thickness) and tin post finish, ensuring consistent electrical performance and reliability.
