SFMC-103-L2-L-D Equivalent & Substitute Parts

Part Overview

The SFMC-103-L2-L-D is a 6-position receptacle connector from Samtec Inc.'s Tiger Eye™ SFMC series, designed for surface mount board-to-board or cable applications. This connector features 0.050" (1.27mm) pitch mating with gold-plated contacts and push-pull fastening. The part is Active status and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector interface, ensuring functional interchangeability in target applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFMC-103-L2-L-D is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 6 positions at 0.050" (1.27mm) mating pitch with 2-row configuration at 0.050" (1.27mm) row spacing
• Mounting & Termination: Surface mount with solder termination
• Electrical Performance: 2.9A per contact current rating
• Environmental Compliance: Operating temperature range -55°C ~ 125°C, UL94 V-0 flammability rating, ROHS3 compliance
• Contact Interface: Gold-plated mating surface with 10.0µin (0.25µm) thickness

The SFMC-103-02-L-D meets all substitution criteria as it maintains identical electrical, mechanical, and environmental specifications while differing only in internal design designation (02 vs. L2 variant code).

Parameter Comparison

Engineering Selection Recommendations

Both the SFMC-103-L2-L-D and SFMC-103-02-L-D are Active status components from Samtec Inc.'s Tiger Eye™ SFMC series. Selection between these parts is based on availability and supply chain requirements rather than functional differences. Both parts maintain ROHS3 compliance, UL94 V-0 flammability certification, and identical electrical specifications. The SFMC-103-02-L-D currently maintains higher inventory availability (2244 pcs vs. 935 pcs), which may influence procurement decisions for high-volume applications. Both parts are suitable for direct substitution in surface mount board-to-board and cable connector applications requiring 6-position 0.050" pitch receptacle interfaces.

Frequently Asked Questions (FAQ)

Q: Can SFMC-103-02-L-D be used as a direct replacement for SFMC-103-L2-L-D?

A: Yes. Both parts are functionally equivalent receptacle connectors with identical mating pitch (0.050"), position count (6), row configuration (2 rows at 0.050" spacing), current rating (2.9A per contact), operating temperature range (-55°C ~ 125°C), and contact finish specifications (gold-plated). They share the same base product number (SFMC-103) and are both ROHS3 compliant with UL94 V-0 flammability rating.

Q: What determines substitution compatibility for SFMC-103 series receptacles?

A: Substitution compatibility is determined by equivalence in connector type (receptacle), contact configuration (female socket), position count and pitch (6 positions at 0.050" mating pitch), row spacing (0.050"), mounting type (surface mount), termination method (solder), electrical performance (2.9A per contact), and environmental ratings (operating temperature, flammability, RoHS compliance).

Q: Are there differences in package or mounting footprint between these parts?

A: No. Both SFMC-103-L2-L-D and SFMC-103-02-L-D are surface mount connectors with identical insulation height (0.185"), contact configuration, and mechanical dimensions. They share the same footprint and mounting requirements.

Q: What is the significance of the variant codes (L2 vs. 02) in the part numbers?

A: The variant codes represent internal design designations within Samtec's product line but do not affect electrical or mechanical compatibility. Both variants maintain identical specifications for mating interface, current handling, temperature range, and compliance certifications.

Q: Are both parts suitable for high-reliability applications?

A: Both SFMC-103-L2-L-D and SFMC-103-02-L-D meet UL94 V-0 flammability requirements and ROHS3 compliance. Both operate across the -55°C ~ 125°C temperature range with 2.9A per contact current rating and maintain MSL 1 (Unlimited) moisture sensitivity level, supporting applications with standard environmental requirements.
