Substitute Part Grouping Explanation

The SFMC-125-02-SM-D-K is a direct substitute for the SFMC-125-T2-S-D-P based on the following critical parameters that determine interchangeability:

• Number of Positions: 50 (identical)
• Pitch - Mating: 0.050" (1.27mm) (identical)
• Number of Rows: 2 (identical)
• Row Spacing - Mating: 0.050" (1.27mm) (identical)
• Connector Type: Receptacle (identical)
• Contact Type: Female Socket (identical)
• Mounting Type: Surface Mount (identical)
• Termination: Solder (identical)
• Fastening Type: Push-Pull (identical)
• Operating Temperature: -55°C ~ 125°C (identical)
• Material Flammability Rating: UL94 V-0 (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

The substitute part differs only in contact material composition (Beryllium Copper vs. Phosphor Bronze) and includes REACH Unaffected status documentation.

Parameter Comparison

Engineering Selection Recommendations

Both SFMC-125-T2-S-D-P and SFMC-125-02-SM-D-K are active production parts with ROHS3 compliance and UL94 V-0 flammability certification. The primary distinction is contact material: Phosphor Bronze in the SFMC-125-T2-S-D-P versus Beryllium Copper in the SFMC-125-02-SM-D-K. All other electrical, mechanical, and environmental specifications are identical. Selection between these parts should be based on specific contact material requirements for your application. The SFMC-125-02-SM-D-K includes REACH Unaffected status documentation. Both parts maintain identical current ratings, operating temperature ranges, and surface mount solder termination characteristics.

Frequently Asked Questions (FAQ)

Q: Are SFMC-125-T2-S-D-P and SFMC-125-02-SM-D-K mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 50 positions, 0.050" (1.27mm) pitch, 2-row configuration, surface mount termination, and push-pull fastening. Physical footprint and mating interface are identical.

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

A: The SFMC-125-T2-S-D-P uses Phosphor Bronze contacts while the SFMC-125-02-SM-D-K uses Beryllium Copper contacts. Both materials are rated for 2.9A per contact with identical gold plating specifications (30.0µin / 0.76µm thickness). Contact material selection depends on application-specific requirements.

Q: Do both parts have the same current rating?

A: Yes. Both SFMC-125-T2-S-D-P and SFMC-125-02-SM-D-K are rated at 2.9A per contact with identical operating temperature range of -55°C to 125°C.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant with UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity level. The SFMC-125-02-SM-D-K includes REACH Unaffected status documentation.

Q: What is the pitch specification for these connectors?

A: Both connectors feature 0.050" (1.27mm) mating pitch with 0.050" (1.27mm) row spacing in a 2-row configuration, resulting in a 50-position receptacle layout.
