TFM-115-12-S-D-A Equivalent & Substitute Parts

Part Overview

The TFM-115-12-S-D-A is a surface mount rectangular connector header manufactured by Samtec Inc. as part of the Tiger Eye™ TFM series. This connector is an active product designed for board-to-board or cable applications with 30 positions arranged in 2 rows at 0.050" (1.27mm) pitch. The component features shrouded 4-wall construction, solder termination, and push-pull fastening. Equivalent and substitute parts within the TFM-115 series provide alternative insulation heights while maintaining core electrical and mechanical compatibility for applications requiring different board spacing or stacking configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts within the TFM-115 series are qualified based on identical electrical and mechanical parameters across all critical connector specifications. The following parameters remain constant across all substitute parts and the main part:

• Connector type, contact type, and gender (Header, Male Pin)
• Number of positions (30) and row configuration (2 rows)
• Pitch specifications (0.050" / 1.27mm mating pitch and row spacing)
• Mounting type (Surface Mount) and termination method (Solder)
• Fastening mechanism (Push-Pull) and shrouding style (Shrouded - 4 Wall)
• Contact material, finish, and electrical ratings (Phosphor Bronze, Gold finish, 2.9A per contact, 275VAC)
• Insulation material (Liquid Crystal Polymer), temperature range, and compliance certifications

The primary variable distinguishing substitute parts is insulation height, which determines the overall connector profile and board spacing capability. This parameter is selected based on specific application requirements for vertical clearance or stacking height.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TFM-115-12-S-D-A, TFM-115-22-S-D-A, and TFM-115-32-S-D-A—are active products from Samtec Inc. with identical compliance certifications including ROHS3 compliance, UL94 V-0 flammability rating, and unlimited moisture sensitivity level (MSL 1). Selection between these parts is determined solely by the required insulation height for the application:

• TFM-115-12-S-D-A: 0.290" (7.37mm) insulation height for compact board spacing
• TFM-115-22-S-D-A: 0.360" (9.14mm) insulation height for standard board spacing
• TFM-115-32-S-D-A: 0.435" (11.05mm) insulation height for increased vertical clearance

All parts maintain identical electrical performance, contact ratings, operating temperature range, and mechanical compatibility within the TFM-115 series. Part selection is based on PCB layout requirements and available vertical space in the application.

Frequently Asked Questions (FAQ)

Q: Are TFM-115-12-S-D-A, TFM-115-22-S-D-A, and TFM-115-32-S-D-A electrically interchangeable?

A: Yes. All three parts share identical electrical specifications including 2.9A per contact current rating, 275VAC voltage rating, contact material (Phosphor Bronze), and contact finish (Gold). The difference is insulation height only, which does not affect electrical performance.

Q: What determines which insulation height to select?

A: Insulation height is selected based on the vertical space available on the PCB and the required clearance between the connector and adjacent components or board layers. The three options provide flexibility for different board layout configurations.

Q: Are these parts compatible with the same mating connectors?

A: Yes. All three parts maintain identical pitch (0.050" / 1.27mm), row spacing (0.050" / 1.27mm), number of positions (30), and row configuration (2 rows). They are compatible with the same mating connectors within the TFM series.

Q: Do all three parts have the same compliance certifications?

A: Yes. All parts are ROHS3 compliant, rated UL94 V-0 for flammability, have MSL 1 (unlimited moisture sensitivity), and are active products from Samtec Inc.

Q: Can I substitute one part for another in an existing design?

A: Substitution is possible only if the PCB layout accommodates the different insulation height of the substitute part. The connector footprint and mating interface remain identical; only the vertical profile changes.
