Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SFMC-118-L2-L-D are qualified based on strict equivalence across the following critical parameters:

• Number of Positions: 36
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Connector Type: Receptacle
• Contact Type: Female Socket
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The three substitute parts (SFMC-118-02-L-D, SFMC-118-02-L-D-K, and SFMC-118-T2-L-D) maintain identical electrical and mechanical specifications across all critical mating and mounting parameters. Variations exist only in contact material composition and specific features, which do not affect functional interchangeability within the defined operating envelope.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain active product status with ROHS3 compliance and UL94 V-0 flammability certification. Selection between SFMC-118-L2-L-D and its substitutes is determined by contact material requirements and assembly process specifications:

SFMC-118-L2-L-D and SFMC-118-02-L-D utilize beryllium copper contacts, providing consistent performance across the full operating temperature range with established reliability data in high-cycle mating applications.

SFMC-118-02-L-D-K incorporates pick-and-place feature compatibility for automated assembly processes, maintaining beryllium copper contact material with identical electrical performance.

SFMC-118-T2-L-D employs phosphor bronze contacts as an alternative contact material while preserving all electrical and mechanical specifications. This variant is suitable for applications where phosphor bronze contact characteristics align with system requirements.

All parts carry MSL 1 (Unlimited) moisture sensitivity classification, eliminating moisture-related handling constraints during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Are these parts mechanically interchangeable?

A: Yes. All four parts share identical mating pitch (0.050"), position count (36), row configuration (2 rows), and surface mount footprint. They are mechanically interchangeable in board-level applications.

Q: What is the difference between SFMC-118-L2-L-D and SFMC-118-02-L-D?

A: Both parts are functionally equivalent with beryllium copper contacts and identical electrical ratings. The primary difference is in internal part numbering within the SFMC-118 base series. No performance distinction exists between these variants.

Q: When should I select SFMC-118-02-L-D-K over the standard variants?

A: SFMC-118-02-L-D-K includes pick-and-place feature compatibility, making it the preferred choice for high-volume automated assembly operations. If manual or non-pick-and-place assembly is used, standard variants are equally suitable.

Q: How does SFMC-118-T2-L-D differ electrically?

A: SFMC-118-T2-L-D maintains identical current rating (2.9A per contact), operating temperature range (-55°C ~ 125°C), and gold mating contact finish. The contact material is phosphor bronze instead of beryllium copper. Both materials meet the specified electrical performance envelope.

Q: Are all parts RoHS compliant?

A: Yes. All four parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity classification, suitable for standard PCB assembly and storage without special handling requirements.

Q: Can I mix these parts in the same design?

A: Yes. All parts are electrically and mechanically equivalent across critical parameters. Mixed usage within a single design presents no compatibility issues provided the mating connector is compatible with the 0.050" pitch and 36-position receptacle configuration.
