Substitute Part Grouping Explanation

The SFM-104-01-L-D has one identified substitute: SFM-104-01-L-D-A. Both parts share the same base product number (SFM-104) and are functionally equivalent based on the following critical parameters:

• 8-position receptacle configuration with 0.050" (1.27mm) pitch
• Female socket contact type with gold mating finish
• 2-row arrangement with 0.050" (1.27mm) row spacing
• Through-hole solder termination with push-pull fastening
• Identical electrical ratings: 3.2A per contact, 250VAC
• Operating temperature range: -55°C ~ 125°C
• UL94 V-0 flammability rating
• ROHS3 compliance

The primary distinction is that SFM-104-01-L-D-A includes a board guide feature, which does not affect electrical or mechanical compatibility but provides enhanced mechanical stability during mating operations.

Parameter Comparison

Engineering Selection Recommendations

Both SFM-104-01-L-D and SFM-104-01-L-D-A are Active status products with identical electrical and mechanical specifications. Selection between these parts should be based on application requirements:

Use SFM-104-01-L-D when standard receptacle functionality is sufficient and board guide features are not required.

Use SFM-104-01-L-D-A when enhanced mechanical alignment during mating operations is beneficial, particularly in applications with frequent connection cycles or where precise connector positioning is critical.

Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, ensuring suitability for regulated industrial and commercial environments. Current inventory levels are 1015 pcs for SFM-104-01-L-D and 689 pcs for SFM-104-01-L-D-A.

Frequently Asked Questions (FAQ)

Q: Are SFM-104-01-L-D and SFM-104-01-L-D-A electrically interchangeable?

A: Yes. Both parts have identical electrical ratings of 3.2A per contact at 250VAC and operate across the same temperature range (-55°C ~ 125°C). They share the same contact material (beryllium copper), contact finish (gold mating, tin post), and insulation material (LCP).

Q: What is the functional difference between these two parts?

A: The SFM-104-01-L-D-A includes a board guide feature that provides mechanical alignment assistance during connector mating. This does not affect electrical performance but improves mechanical stability in applications requiring frequent connections.

Q: Can I substitute SFM-104-01-L-D-A for SFM-104-01-L-D in existing designs?

A: Yes, provided your PCB layout accommodates the board guide feature. The board guide does not introduce electrical incompatibility and maintains identical pitch, row spacing, and mounting characteristics.

Q: Are both parts RoHS compliant?

A: Yes. Both SFM-104-01-L-D and SFM-104-01-L-D-A are ROHS3 compliant and carry UL94 V-0 flammability certification.

Q: What are the mated stacking heights for these connectors?

A: Both parts support identical mated stacking heights: 6.02mm, 6.17mm, 7.80mm, 7.95mm, 9.58mm, 9.73mm, 11.48mm, and 11.63mm, depending on the mating connector configuration.

Q: Are there any moisture sensitivity considerations?

A: SFM-104-01-L-D has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. SFM-104-01-L-D-A lists MSL as Not Applicable, which is consistent with the connector's robust LCP insulation material.
