Key Parameters

Substitute Part Grouping Explanation

The SFMC-102-L2-S-D has one identified substitute part: SFMC-102-T2-S-D. Both parts share the same base product number (SFMC-102) and are functionally equivalent within the Tiger Eye™ SFMC series. Substitution is valid based on the following matching parameters:

• Connector type, contact type, and style (Receptacle, Female Socket, Board to Board or Cable)
• Number of positions and row configuration (4 positions, 2 rows)
• Pitch and row spacing (0.050" mating pitch and row spacing)
• Mounting type and termination method (Surface Mount, Solder)
• Fastening mechanism (Push-Pull)
• Mating contact finish and thickness (Gold, 30.0µin)
• Insulation material, color, and height (LCP, Black, 0.185")
• Contact shape (Square)
• Current rating (2.9A per Contact)
• Operating temperature range (-55°C ~ 125°C)
• Material flammability rating (UL94 V-0)
• Compliance standards (ROHS3 Compliant, MSL 1)

The primary difference between these parts is the contact material used for the post termination: SFMC-102-L2-S-D uses Beryllium Copper, while SFMC-102-T2-S-D uses Phosphor Bronze. Both materials are acceptable for the specified electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

Both SFMC-102-L2-S-D and SFMC-102-T2-S-D are active production parts with full ROHS3 compliance and UL94 V-0 material flammability certification. Selection between these parts should be based on availability and post contact material requirements. The SFMC-102-T2-S-D currently has higher inventory availability (1175 units versus 783 units). Both parts meet identical electrical performance specifications, operating temperature ranges, and mechanical interface requirements. The contact material difference (Beryllium Copper versus Phosphor Bronze) does not affect the mating interface or electrical performance within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can SFMC-102-T2-S-D be used as a direct replacement for SFMC-102-L2-S-D?

A: Yes. Both parts are functionally equivalent receptacle connectors within the Tiger Eye™ SFMC series with identical mating interfaces, pitch, row spacing, mounting type, and electrical ratings. The post contact material differs (Beryllium Copper versus Phosphor Bronze), but both materials meet the specified current and temperature requirements.

Q: What is the difference between these two part numbers?

A: The primary difference is the contact material used for the post termination. SFMC-102-L2-S-D uses Beryllium Copper, while SFMC-102-T2-S-D uses Phosphor Bronze. All other mechanical, electrical, and environmental specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both SFMC-102-L2-S-D and SFMC-102-T2-S-D are ROHS3 compliant and carry UL94 V-0 material flammability certification.

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

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

Q: Can these connectors be used in high-temperature applications?

A: Yes. Both parts are rated for operating temperatures from -55°C to 125°C, suitable for industrial and automotive applications within this range.

Q: What is the current capacity per contact?

A: Both connectors are rated for 2.9A per contact, providing consistent electrical performance across the 4-position configuration.
