SFMC-105-02-S-D Equivalent & Substitute Parts

Part Overview

The SFMC-105-02-S-D is a 10-position receptacle connector from Samtec Inc.'s Tiger Eye™ SFMC series, designed for surface mount board-to-board or cable applications. This connector features 0.050" (1.27mm) pitch mating with gold-plated contacts rated for 2.9A per contact and operates across -55°C to 125°C. The part is actively produced and ROHS3 compliant with UL94 V-0 flammability rating. Alternative models within the same series may be required due to inventory availability, specific termination requirements, or contact material specifications for particular application demands.

Substitute Part Grouping Explanation

The SFMC-105-T2-S-D qualifies as a direct substitute for the SFMC-105-02-S-D based on the following critical parameters that determine interchangeability:

• Connector Configuration: Both are 10-position receptacles with identical 0.050" (1.27mm) pitch and 2-row layout
• Mating Interface: Identical row spacing (0.050"), contact finish (gold), and fastening mechanism (push-pull)
• Electrical Performance: Both rated for 2.9A per contact with identical operating temperature range (-55°C ~ 125°C)
• Compliance & Safety: Both ROHS3 compliant, UL94 V-0 rated, and MSL 1
• Mounting & Termination: Both surface mount with solder termination

The primary difference between these parts is the contact material composition: the main part uses Beryllium Copper contacts, while the substitute uses Phosphor Bronze contacts. Both materials are acceptable for this connector class and do not affect mechanical or electrical compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SFMC-105-02-S-D and SFMC-105-T2-S-D are active production parts with full ROHS3 compliance and UL94 V-0 certification. Selection between these parts should be based on:

• Availability: The SFMC-105-T2-S-D offers higher inventory (1666 pcs vs. 903 pcs), providing better supply chain assurance
• Contact Material Specification: If your application specifies Beryllium Copper contacts, use SFMC-105-02-S-D. If Phosphor Bronze is acceptable or preferred, SFMC-105-T2-S-D is suitable
• Regulatory Requirements: Both parts meet identical compliance standards (ROHS3, REACH Unaffected, EAR99 classification)
• Environmental Conditions: Both operate identically across the -55°C to 125°C range with MSL 1 rating

Frequently Asked Questions (FAQ)

Q: Are SFMC-105-02-S-D and SFMC-105-T2-S-D mechanically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, pitch spacing (0.050"), row configuration (2 rows), and mounting footprint for surface mount applications. They are direct mechanical substitutes.

Q: What is the difference between Beryllium Copper and Phosphor Bronze contacts?

A: Both materials are used in connector contact applications. Beryllium Copper (SFMC-105-02-S-D) and Phosphor Bronze (SFMC-105-T2-S-D) differ in material composition but deliver the same electrical performance (2.9A per contact) and contact finish specifications for this connector series.

Q: Do both parts have the same solder termination compatibility?

A: Yes. Both parts feature identical solder termination and tin post finish, ensuring compatibility with standard PCB assembly processes.

Q: Are there any compliance differences between these substitutes?

A: No. Both parts are ROHS3 compliant, REACH unaffected, UL94 V-0 rated, and classified as EAR99. They meet identical regulatory and safety standards.

Q: Which part should I select for new designs?

A: Either part is suitable for new designs. Selection should be based on contact material requirements, inventory availability, and any specific material specifications in your design documentation. Both are active production parts with unlimited moisture sensitivity level (MSL 1).
