Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connectors in the SFMC series is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Arrangement: 4 positions in 2-row configuration
• Pitch Specifications: 0.050" (1.27mm) mating pitch and row spacing
• Mounting & Termination: Surface mount with solder termination
• Contact Material & Finish: Beryllium copper with gold mating surface (10.0µin thickness) and tin post finish
• Electrical Performance: 2.9A per contact current rating
• Environmental Compliance: UL94 V-0 flammability, ROHS3 compliance, MSL 1 rating
• Operating Range: -55°C to 125°C temperature specification

The substitute part SFMC-102-02-L-D maintains identical specifications across all these parameters, confirming direct substitutability within the Tiger Eye™ SFMC series.

Parameter Comparison

Engineering Selection Recommendations

Both SFMC-102-L2-L-D and SFMC-102-02-L-D are active production parts with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is based on inventory availability and procurement lead time requirements. The SFMC-102-02-L-D currently maintains higher stock levels (1031 units versus 860 units), which may support shorter delivery schedules for high-volume applications. Both parts carry identical electrical specifications, environmental ratings, and mechanical compatibility, ensuring interchangeable performance in board-to-board and cable connector applications requiring 4-position, 0.050" pitch surface mount receptacles with gold-plated contacts.

Frequently Asked Questions (FAQ)

Q: Can SFMC-102-02-L-D be used as a direct replacement for SFMC-102-L2-L-D?

A: Yes. Both parts are identical across all specified electrical, mechanical, and environmental parameters. They share the same base product number (SFMC-102), connector configuration, pitch specifications, contact materials, and compliance certifications.

Q: What determines substitutability for SFMC series rectangular connectors?

A: Substitutability is determined by matching connector type (receptacle), position count (4), pitch specifications (0.050" mating and row spacing), mounting method (surface mount), contact configuration (female socket), contact finish (gold mating surface), current rating (2.9A per contact), and environmental ratings (UL94 V-0, ROHS3, MSL 1).

Q: Are there differences in the part numbers SFMC-102-L2-L-D and SFMC-102-02-L-D?

A: The part numbers differ in their configuration designators (L2 versus 02), but both parts conform to identical specifications for the 4-position, 0.050" pitch receptacle connector. The base product number SFMC-102 is common to both.

Q: What is the current rating for these connectors?

A: Both parts are rated for 2.9A per contact, supporting applications requiring moderate current distribution across multiple signal or power paths.

Q: Are these connectors suitable for high-temperature applications?

A: Yes. Both parts operate across the -55°C to 125°C temperature range and carry UL94 V-0 flammability certification, supporting industrial and automotive applications within this thermal envelope.

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

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