Substitute Part Grouping Explanation

Substitution eligibility for the TFC-115-32-L-D-A is determined by strict equivalence across the following critical parameters:

Electrical compatibility requires matching pitch (0.050" / 1.27mm), number of positions (30), row configuration (2 rows), contact type (Male Pin), current rating (3.1A per Contact), and voltage rating (275VAC).

Mechanical compatibility requires matching connector type (Header), mounting type (Surface Mount), shrouding configuration (Shrouded - 4 Wall), fastening type (Push-Pull), and termination method (Solder).

Environmental and regulatory compliance requires matching operating temperature range (-55°C ~ 125°C), material flammability rating (UL94 V-0), RoHS status (ROHS3 Compliant), and moisture sensitivity level (MSL 1).

The substitute part TFC-115-12-L-D-A meets all electrical, mechanical, and regulatory requirements for direct substitution. The only variance is insulation height, which differs between the main part (0.441" / 11.20mm) and the substitute (0.296" / 7.52mm). This dimensional difference does not affect electrical performance or mating compatibility when used in board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Both TFC-115-32-L-D-A and TFC-115-12-L-D-A are active production parts from Samtec Inc. with full ROHS3 compliance and REACH unaffected status. Both parts carry UL94 V-0 material flammability certification and MSL 1 moisture sensitivity rating, indicating suitability for standard manufacturing and storage environments without special handling requirements.

The TFC-115-12-L-D-A substitute part is electrically and mechanically equivalent for board-to-board connector applications. The reduced insulation height (7.52mm versus 11.20mm) represents a dimensional optimization that does not compromise electrical performance, contact integrity, or mating reliability. Selection between these parts should be based on available inventory, lead time requirements, and specific board layout constraints where insulation height is a design consideration.

Frequently Asked Questions (FAQ)

Q: Can TFC-115-12-L-D-A be used as a direct replacement for TFC-115-32-L-D-A?

A: Yes. Both parts share identical electrical specifications (30 positions, 0.050" pitch, 3.1A per contact, 275VAC rating), mechanical configuration (2-row header, surface mount, shrouded 4-wall, push-pull fastening), and regulatory compliance (ROHS3, UL94 V-0, MSL 1). The insulation height difference does not affect mating compatibility or electrical performance in standard board-to-board applications.

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

A: Insulation height affects the overall profile of the connector body. The TFC-115-32-L-D-A has an insulation height of 11.20mm, while the TFC-115-12-L-D-A measures 7.52mm. This dimensional difference may be relevant for applications with strict height constraints or specific board-to-board spacing requirements. Verify that the reduced height does not conflict with your PCB layout or enclosure design before substitution.

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

A: Yes. Both TFC-115-32-L-D-A and TFC-115-12-L-D-A operate across the identical temperature range of -55°C to 125°C, ensuring thermal compatibility in equivalent applications.

Q: What is the current handling capacity per contact?

A: Both parts are rated for 3.1A per contact at 275VAC, providing identical electrical load capacity for signal and power distribution in board-to-board interconnect designs.

Q: Do both parts require special handling or storage conditions?

A: No. Both parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating they do not require special moisture control or baking procedures prior to assembly. Standard manufacturing and storage environments are appropriate.

Q: Are there any compliance or certification differences between these parts?

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