TFM-105-12-S-D Equivalent & Substitute Parts

Part Overview

The TFM-105-12-S-D is a surface mount rectangular connector header manufactured by Samtec Inc. as part of the Tiger Eye™ TFM series. This 10-position, 2-row connector with 0.050" (1.27mm) pitch is designed for board-to-board or cable applications requiring shrouded, push-pull fastening. The part is currently active in production with 803 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, design flexibility, or application-specific requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFM-105-12-S-D is determined by the following critical parameters:

• Connector Type & Contact Type: Must be Header with Male Pin configuration
• Position & Row Configuration: Must maintain 10 positions in 2 rows
• Pitch Specifications: Mating pitch and row spacing must both be 0.050" (1.27mm)
• Mounting & Termination: Surface mount with solder termination required
• Shrouding & Fastening: Shrouded 4-wall design with push-pull fastening
• Material Compliance: Liquid Crystal Polymer insulation and phosphor bronze contacts
• Environmental Ratings: RoHS3 compliance and MSL 1 rating

The substitute part 5-104656-1 (TE Connectivity AMP Connectors AMPMODU 50/50 Grid series) meets all critical substitution criteria across these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the TFM-105-12-S-D and 5-104656-1 are active production parts with ROHS3 compliance and MSL 1 ratings, making them suitable for equivalent substitution in applications where the specified electrical and mechanical parameters are compatible.

The TFM-105-12-S-D offers higher current capacity (2.9A per contact) and specified voltage rating (275VAC), with an extended upper operating temperature limit of 125°C. This configuration is appropriate for higher-power applications or those requiring explicit voltage specifications.

The 5-104656-1 provides extended lower operating temperature capability (-65°C minimum) and includes Board Lock features. The lower current rating (0.5A per contact) and unspecified voltage rating indicate suitability for general-purpose, low-power signal applications. This part has higher inventory availability (3162 units in stock).

Selection between these parts should be based on application current and voltage requirements, operating temperature range, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 5-104656-1 be used as a direct replacement for the TFM-105-12-S-D?

A: Both parts share identical pitch (0.050" / 1.27mm), position count (10), row configuration (2), mounting type (surface mount), shrouding (4-wall), termination (solder), and fastening (push-pull). Substitution is mechanically and electrically compatible for applications within the 5-104656-1 current rating (0.5A per contact) and operating temperature range (-65°C to 105°C).

Q: What are the key differences between these two connectors?

A: The primary differences are current rating (TFM-105-12-S-D: 2.9A vs. 5-104656-1: 0.5A per contact), operating temperature range (TFM-105-12-S-D: -55°C to 125°C vs. 5-104656-1: -65°C to 105°C), contact length (0.139" vs. 0.120"), and insulation height (0.290" vs. 0.298"). The 5-104656-1 includes Board Lock features.

Q: Are there any package or footprint considerations?

A: Both connectors use surface mount termination with identical pitch and row spacing. Minor variations in contact length and insulation height may affect mating depth and PCB layout spacing. Physical dimensions should be verified against specific board design requirements.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and share the same ECCN (EAR99) and HTSUS code (8536.69.4040).

Q: Which part should be selected for high-current applications?

A: The TFM-105-12-S-D is specified for 2.9A per contact and is appropriate for higher-current applications. The 5-104656-1 is rated for 0.5A per contact and is suitable for low-power signal applications.
