Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFMC-105-02-L-D is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (10)
• Pitch specification (0.050" / 1.27mm)
• Number of rows (2)
• Row spacing (0.050" / 1.27mm)
• Mounting type (Surface Mount)
• Mating contact finish (Gold)
• Operating temperature range (-55°C ~ 125°C)
• Current rating (2.9A per Contact)
• Fastening type (Push-Pull)
• Insulation material (Liquid Crystal Polymer)
• RoHS and REACH compliance status

The SFMC-105-T2-L-D qualifies as a direct substitute based on identical values across all these parameters. The difference in contact material (Phosphor Bronze vs. Beryllium Copper) does not affect substitution eligibility, as both materials meet the specified electrical and mechanical requirements for this connector category.

Parameter Comparison

Engineering Selection Recommendations

Both SFMC-105-02-L-D and SFMC-105-T2-L-D are active production parts with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on inventory availability and application-specific requirements related to contact material performance. The SFMC-105-02-L-D features Beryllium Copper contacts, while the SFMC-105-T2-L-D uses Phosphor Bronze contacts. Both materials satisfy the specified electrical and mechanical parameters for this connector category. The SFMC-105-02-L-D currently maintains higher inventory levels at 1167 units compared to 1070 units for the SFMC-105-T2-L-D.

Frequently Asked Questions (FAQ)

Q: Can SFMC-105-T2-L-D be used as a direct replacement for SFMC-105-02-L-D?

A: Yes. Both connectors share identical specifications across all critical parameters including connector type, position count, pitch, mounting type, contact finish, current rating, and operating temperature range. The difference in contact material does not affect substitution eligibility.

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

A: Both materials are specified for this connector series and meet the electrical and mechanical requirements. The contact material difference is a design variation within the SFMC-105 base product family.

Q: Are there any packaging or handling differences between these parts?

A: Both parts are supplied in tube packaging with identical moisture sensitivity level (MSL 1 - Unlimited), indicating no special storage or handling requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SFMC-105-02-L-D and SFMC-105-T2-L-D are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability ratings.

Q: Which part should be selected based on availability?

A: Selection should be based on current inventory requirements and project timeline. The SFMC-105-02-L-D has 1167 units in stock, while the SFMC-105-T2-L-D has 1070 units available.
