Part Overview

The Samtec TFM-115-32-S-D is a surface mount rectangular connector header from the Tiger Eye™ TFM series, designed for board-to-board or cable applications. This 30-position connector operates across -55°C to 125°C with a 0.050" (1.27mm) pitch and supports 2.9A per contact at 275VAC. The part is active and in production with full RoHS3 compliance and MSL 1 rating. Equivalent and substitute parts within the TFM-115 series are identified based on matching core electrical and mechanical parameters while accommodating variations in insulation height and mounting features.

Substitute Part Grouping Explanation

Substitution within the TFM-115 series is determined by three core parameters: pitch (0.050" / 1.27mm), number of positions (30), and row configuration (2 rows). All substitute parts maintain these electrical and mechanical constants. Variations occur in insulation height and mounting features, which do not affect electrical compatibility but influence physical board layout and connector engagement characteristics.

The substitute parts are grouped by insulation height:

Group 1 - Insulation Height 0.290" (7.37mm): TFM-115-12-S-D-A and TFM-115-12-S-D-LC. These parts feature reduced insulation height suitable for compact applications.

Group 2 - Insulation Height 0.360" (9.14mm): TFM-115-22-S-D-A and TFM-115-22-S-D-LC. These parts provide mid-range insulation height with board guide or board lock features.

Group 3 - Insulation Height 0.435" (11.05mm): TFM-115-32-S-D-A, TFM-115-32-S-D-A-P, and TFM-115-32-S-D-LC. These parts match the main part's insulation height with variations in mounting features (board guide, board lock, or pick-and-place compatibility).

Engineering Selection Recommendations

All substitute parts maintain identical electrical specifications: 30 positions, 0.050" pitch, 2.9A per contact, 275VAC rating, and -55°C to 125°C operating range. All are active products with ROHS3 compliance and MSL 1 rating.

Selection between substitute parts depends on board layout constraints and connector engagement requirements:

For applications with space limitations, TFM-115-12-S-D-A or TFM-115-12-S-D-LC provide the lowest profile at 0.290" insulation height.

For mid-range applications, TFM-115-22-S-D-A or TFM-115-22-S-D-LC offer 0.360" insulation height with board guide or board lock features.

For applications matching the original part's 0.435" insulation height, TFM-115-32-S-D-A provides board guide functionality, TFM-115-32-S-D-LC provides board lock functionality, and TFM-115-32-S-D-A-P adds pick-and-place compatibility for automated assembly.

Board guide features (-A suffix) provide alignment during mating. Board lock features (-LC suffix) provide positive retention. Pick-and-place features (-P suffix) support automated component placement equipment.

Frequently Asked Questions (FAQ)

Q: Can TFM-115-12-S-D-A replace TFM-115-32-S-D in my application?

A: Electrical compatibility is maintained. However, the insulation height differs: TFM-115-12-S-D-A is 0.290" versus TFM-115-32-S-D at 0.435". This 0.145" difference affects board layout and mating connector clearance. Verify your PCB design accommodates the reduced height before substitution.

Q: What is the difference between board guide (-A) and board lock (-LC) features?

A: Board guide features provide alignment assistance during connector mating. Board lock features provide positive mechanical retention after mating. Selection depends on application requirements for connector stability and ease of disconnection.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts are ROHS3 compliant with MSL 1 rating, matching the original TFM-115-32-S-D specifications.

Q: Can I use TFM-115-32-S-D-A-P in manual assembly applications?

A: Yes. The pick-and-place feature (-P suffix) is an additional capability for automated assembly compatibility. The part functions identically in manual assembly applications.

Q: Do insulation height variations affect electrical performance?

A: No. Insulation height variations do not affect electrical specifications. All parts maintain 2.9A per contact, 275VAC rating, and identical contact materials and finishes. Height differences are mechanical design variations for different board layout requirements.
