TFC-145-22-L-D-A Equivalent & Substitute Parts

Part Overview

The TFC-145-22-L-D-A is a Samtec Tiger Eye™ TFC series rectangular connector header designed for surface mount applications. This shrouded 4-wall header features 90 positions arranged in 2 rows with 0.050" (1.27mm) pitch, suitable for board-to-board or cable connections. The connector is actively produced and maintains full RoHS3 compliance with UL94 V-0 flammability rating. Substitute parts may be required due to inventory constraints, application-specific insulation height requirements, or design revisions necessitating compatible alternatives within the same product series.

Key Parameters

Substitute Part Grouping Explanation

The TFC-145-32-L-D-A qualifies as a direct substitute based on the following critical parameters that remain identical:

Manufacturer and series (Samtec Tiger Eye™ TFC), connector type (Header), contact type (Male Pin), number of positions (90), number of rows (2), mating pitch (0.050"), row spacing (0.050"), mounting type (Surface Mount), shrouding configuration (Shrouded - 4 Wall), termination method (Solder), fastening type (Push-Pull), contact shape (Square), contact material (Phosphor Bronze), insulation material (Liquid Crystal Polymer), contact finish specifications (Gold mating surface with 10.0µin thickness, Tin post finish), current rating (3.1A per Contact), voltage rating (275VAC), operating temperature range (-55°C ~ 125°C), flammability rating (UL94 V-0), and compliance certifications (ROHS3, MSL 1).

The primary difference is insulation height: TFC-145-22-L-D-A specifies 0.366" (9.30mm) while TFC-145-32-L-D-A specifies 0.441" (11.20mm). This dimensional variation accommodates different PCB stackup requirements while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both TFC-145-22-L-D-A and TFC-145-32-L-D-A are active products from Samtec with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts depends solely on PCB design requirements for insulation height clearance. The TFC-145-22-L-D-A with 0.366" (9.30mm) insulation height is suitable for compact stackup designs with limited vertical space. The TFC-145-32-L-D-A with 0.441" (11.20mm) insulation height accommodates applications requiring greater clearance above the PCB surface. Both parts maintain identical electrical performance, thermal ratings, and contact specifications, ensuring functional interchangeability when mechanical constraints permit.

Frequently Asked Questions (FAQ)

Q: Are TFC-145-22-L-D-A and TFC-145-32-L-D-A electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 3.1A per contact current rating, 275VAC voltage rating, contact material (Phosphor Bronze), contact finish (Gold mating, Tin post), and operating temperature range (-55°C ~ 125°C).

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

A: The insulation height differs. TFC-145-22-L-D-A specifies 0.366" (9.30mm) while TFC-145-32-L-D-A specifies 0.441" (11.20mm). This dimension affects vertical clearance on the PCB but does not impact electrical performance.

Q: Can I substitute TFC-145-32-L-D-A for TFC-145-22-L-D-A in my design?

A: Substitution is possible only if your PCB layout accommodates the increased insulation height of 0.441" (11.20mm). Verify clearance above the PCB surface before implementing this change.

Q: Do both parts have the same contact pitch and row spacing?

A: Yes. Both parts feature 0.050" (1.27mm) mating pitch and 0.050" (1.27mm) row spacing, ensuring mechanical compatibility with mating connectors.

Q: Are both parts RoHS compliant?

A: Yes. Both TFC-145-22-L-D-A and TFC-145-32-L-D-A are ROHS3 compliant with UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.

Q: What is the mounting configuration for both parts?

A: Both parts are surface mount headers with shrouded 4-wall design, solder termination, and push-pull fastening type, suitable for board-to-board or cable connections.
