TFM-115-32-L-D Equivalent & Substitute Parts

Part Overview

The TFM-115-32-L-D 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 part is ROHS3 compliant and rated for operating temperatures from -55°C to 125°C. Equivalent and substitute parts within this series provide alternative configurations while maintaining core electrical and mechanical compatibility for applications requiring connector interchangeability.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the TFM-115 series is determined by the following critical parameters that must remain constant:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (30)
• Number of rows (2)
• Pitch - mating (0.050" / 1.27mm)
• Row spacing - mating (0.050" / 1.27mm)
• Mounting type (Surface Mount)
• Shrouding (Shrouded - 4 Wall)
• Termination (Solder)
• Fastening type (Push-Pull)
• Contact shape (Square)
• Contact material (Phosphor Bronze)
• Insulation material (Liquid Crystal Polymer)
• Current rating (2.9A per Contact)
• Voltage rating (275VAC)
• Operating temperature range (-55°C ~ 125°C)
• RoHS compliance (ROHS3)
• MSL rating (1 - Unlimited)

Variations between the main part and substitutes are limited to insulation height and the presence of board guide features, which do not affect electrical compatibility or core mechanical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TFM-115-32-L-D, TFM-115-32-L-D-A, and TFM-115-22-L-D-A—are active products from Samtec Inc. with identical ROHS3 compliance and UL94 V-0 flammability ratings. They share the same electrical specifications, including current rating (2.9A per contact), voltage rating (275VAC), and operating temperature range (-55°C to 125°C).

The primary distinction between TFM-115-32-L-D and TFM-115-32-L-D-A is the addition of board guide features in the latter variant, which provides enhanced mechanical stability during mating without affecting electrical performance. Both maintain an insulation height of 0.435" (11.05mm).

TFM-115-22-L-D-A differs only in insulation height at 0.360" (9.14mm) while retaining board guide features. This reduced height may be selected for applications with space constraints, provided the PCB layout accommodates the lower profile.

Selection should be based on available inventory, required mechanical features (board guide presence), and physical space constraints within the application. All three parts maintain full electrical and thermal compatibility.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical electrical specifications, pitch, row spacing, contact configuration, and termination method. The addition of board guide features in the -A variant provides enhanced mechanical alignment without affecting electrical compatibility.

Q: What is the functional difference between TFM-115-32-L-D-A and TFM-115-22-L-D-A?

A: The primary difference is insulation height: TFM-115-32-L-D-A measures 0.435" (11.05mm) while TFM-115-22-L-D-A measures 0.360" (9.14mm). Both include board guide features and maintain identical electrical ratings and contact configurations. Selection depends on available vertical space in the application.

Q: Are all three parts RoHS compliant?

A: Yes. TFM-115-32-L-D, TFM-115-32-L-D-A, and TFM-115-22-L-D-A are all ROHS3 compliant with UL94 V-0 flammability ratings.

Q: What does the board guide feature provide?

A: Board guide features enhance mechanical stability and alignment during connector mating by providing additional contact guidance. This does not alter electrical performance or current/voltage ratings.

Q: Are there any temperature or current rating differences between these parts?

A: No. All three parts operate across -55°C to 125°C and are rated for 2.9A per contact at 275VAC.

Q: What is the moisture sensitivity level for these connectors?

A: All three parts have MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
