Key Parameters

Substitute Part Grouping Explanation

Substitution within the SFMC-110 series is determined by equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (20), mating pitch (0.050"), row configuration (2 rows at 0.050" spacing), mounting type (surface mount), termination method (solder), fastening type (push-pull), mating contact finish (gold at 30.0µin), current rating (2.9A per contact), operating temperature range (-55°C to 125°C), insulation material (LCP), and flammability rating (UL94 V-0).

The substitute parts SFMC-110-02-S-D and SFMC-110-T2-S-D maintain all these parameters identically. The primary distinction lies in the contact material composition: SFMC-110-L2-S-D and SFMC-110-02-S-D utilize Beryllium Copper contacts, while SFMC-110-T2-S-D employs Phosphor Bronze contacts. Both contact materials are functionally equivalent within the specified electrical and thermal operating envelope. All three parts share the same base product number (SFMC-110), series designation, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SFMC-110-L2-S-D, SFMC-110-02-S-D, and SFMC-110-T2-S-D—are active production components with identical electrical performance specifications and full compliance with ROHS3 and UL94 V-0 flammability requirements. Selection between these parts is based on contact material availability and inventory levels rather than functional differences.

SFMC-110-L2-S-D and SFMC-110-02-S-D, both utilizing Beryllium Copper contacts, are functionally equivalent and interchangeable. SFMC-110-T2-S-D, with Phosphor Bronze contacts, provides an alternative material composition while maintaining all specified electrical and thermal performance parameters. The choice between Beryllium Copper and Phosphor Bronze contact materials does not affect connector performance within the stated operating conditions.

Current inventory levels are: SFMC-110-T2-S-D (1138 units), SFMC-110-L2-S-D (954 units), and SFMC-110-02-S-D (910 units). All parts are available in tube packaging and carry MSL 1 (Unlimited) moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Are SFMC-110-L2-S-D, SFMC-110-02-S-D, and SFMC-110-T2-S-D directly interchangeable?

A: Yes. All three parts share identical connector type, position count, pitch, row configuration, mounting method, termination, fastening type, contact finish specifications, current rating, operating temperature range, and flammability rating. The contact material difference (Beryllium Copper versus Phosphor Bronze) does not affect interchangeability within the specified electrical and thermal operating envelope.

Q: What is the functional difference between Beryllium Copper and Phosphor Bronze contacts in these connectors?

A: Both materials meet the specified 2.9A per contact current rating and -55°C to 125°C operating temperature range. The contact material composition is an internal design parameter that does not alter the connector's electrical performance or mechanical compatibility.

Q: Can I substitute SFMC-110-T2-S-D for SFMC-110-L2-S-D in an existing design?

A: Yes. Both parts maintain identical mating pitch (0.050"), row spacing (0.050"), insulation height (0.185"), contact finish (gold at 30.0µin), and all other critical parameters. No design modification is required.

Q: Are all three parts RoHS3 compliant?

A: Yes. SFMC-110-L2-S-D, SFMC-110-02-S-D, and SFMC-110-T2-S-D are all ROHS3 compliant with UL94 V-0 flammability rating.

Q: What is the MSL rating for these connectors?

A: All three parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there any packaging differences between these parts?

A: All three parts are supplied in tube packaging. No packaging variation exists between the substitute options.
