Key Parameters

Substitute Part Grouping Explanation

Substitution within the SFML-110-02 connector family is determined by strict equivalence of core electrical and mechanical parameters: connector type (receptacle), position count (20), mating pitch (0.050"), row configuration (2 rows at 0.050" spacing), surface mount termination, gold contact finish, current rating (3.2A), and voltage rating (250VAC). All substitute parts maintain identical operating temperature range (-55°C ~ 125°C), UL94 V-0 flammability rating, ROHS3 compliance, and MSL 1 classification.

Substitutes differ only in fastening mechanism designation and optional board-level features:

• SFML-110-02-L-D: Standard locking ramp fastening
• SFML-110-02-L-D-A: Includes board guide feature
• SFML-110-02-L-D-LC: Includes board lock feature

The main part SFML-110-02-LM-D incorporates a locking mechanism variant (LM designation) that is functionally equivalent to the L-D base configuration for mating and electrical performance.

Parameter Comparison

Engineering Selection Recommendations

All four connector variants maintain active product status and full ROHS3 compliance with identical electrical ratings, operating temperature range, and flammability certification. Selection between SFML-110-02-LM-D and its substitutes is based on board-level mechanical requirements:

SFML-110-02-L-D provides the baseline configuration with standard locking ramp fastening for applications requiring basic mechanical retention.

SFML-110-02-L-D-A includes board guide feature for applications requiring enhanced mechanical alignment during mating operations.

SFML-110-02-L-D-LC includes board lock feature for applications requiring positive mechanical locking after mating.

SFML-110-02-LM-D incorporates the LM fastening variant, functionally equivalent to L-D for electrical and mating performance.

All parts share identical contact ratings (3.2A per contact, 250VAC), gold mating surface finish (10.0µin thickness), tin post finish, and LCP insulation material. Substitution is valid where board-level mechanical features do not conflict with application requirements.

Frequently Asked Questions (FAQ)

Q: Can SFML-110-02-L-D-A (board guide) be substituted for SFML-110-02-LM-D in existing designs?

A: Yes, provided the PCB layout accommodates the board guide feature. The board guide adds mechanical alignment capability without affecting electrical performance or mating pitch. Verify PCB cutout dimensions match the board guide profile.

Q: What is the functional difference between SFML-110-02-L-D-LC (board lock) and SFML-110-02-LM-D?

A: Both maintain identical electrical ratings and mating characteristics. The board lock feature (LC) provides positive mechanical locking after mating, while the LM variant uses standard locking ramp fastening. Selection depends on application-level mechanical retention requirements.

Q: Are all four variants compatible with the same mating connector?

A: Yes. All variants share identical 20-position, 0.050" pitch configuration with 2-row, 0.050" row spacing. Mating compatibility is determined by pitch and position count, not by fastening mechanism or board-level features.

Q: What is the inventory advantage of SFML-110-02-L-D-A?

A: SFML-110-02-L-D-A has 4985 units in stock compared to 1083 units for SFML-110-02-LM-D, providing greater availability for high-volume production requirements.

Q: Do all variants meet the same compliance standards?

A: Yes. All four parts are ROHS3 compliant, UL94 V-0 rated, MSL 1 classified, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: Can SFML-110-02-L-D (standard) replace SFML-110-02-LM-D without design modification?

A: Yes, provided the application does not require the specific fastening mechanism of the LM variant. Electrical performance, mating pitch, contact ratings, and operating temperature range are identical.
