Substitute Part Grouping Explanation

The SFMC-109-01-S-D qualifies as a direct substitute for the SFMC-109-L1-S-D based on identical electrical and mechanical parameters. Both parts share the same base product number (SFMC-109) and maintain equivalence across all critical substitution criteria:

• 18-position receptacle configuration with identical pitch spacing (0.050" mating pitch, 0.050" row spacing)
• Identical contact specifications: female socket, square shape, beryllium copper material with gold mating finish (30.0µin thickness)
• Matching termination and mounting: through-hole solder termination with push-pull fastening
• Identical performance ratings: 2.9A per contact, -55°C to 125°C operating range
• Equivalent compliance: UL94 V-0 flammability rating, ROHS3 compliant
• Same insulation material (Liquid Crystal Polymer) and color (Black)

Parameter Comparison

Engineering Selection Recommendations

Both the SFMC-109-L1-S-D and SFMC-109-01-S-D are active production parts from Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts may be based on inventory availability: SFMC-109-L1-S-D has 1,015 units in stock, while SFMC-109-01-S-D has 986 units in stock. Both parts carry identical electrical performance specifications, mechanical dimensions, and environmental ratings, making them fully interchangeable for board-to-board and cable connector applications requiring 18-position, 0.050" pitch receptacle configurations with push-pull fastening.

Frequently Asked Questions (FAQ)

Q: Are SFMC-109-L1-S-D and SFMC-109-01-S-D electrically interchangeable?

A: Yes. Both parts are rated for 2.9A per contact with identical gold mating contact finish (30.0µin thickness) and beryllium copper contact material. Operating temperature range (-55°C to 125°C) and flammability rating (UL94 V-0) are identical.

Q: Do these connectors have the same physical footprint?

A: Yes. Both parts feature 18 positions arranged in 2 rows with 0.050" (1.27mm) mating pitch and 0.050" row spacing. Through-hole mounting dimensions, insulation height (0.180"), and contact post length (0.120") are identical.

Q: What is the difference between SFMC-109-L1-S-D and SFMC-109-01-S-D?

A: Both parts share the same base product number (SFMC-109) and are functionally equivalent. The difference lies in the part number suffix, which may indicate different manufacturing batches or packaging configurations, but all electrical and mechanical specifications remain identical.

Q: Are both parts RoHS compliant?

A: Yes. Both SFMC-109-L1-S-D and SFMC-109-01-S-D are ROHS3 compliant and carry EAR99 export classification.

Q: Can I use these connectors in high-temperature applications?

A: Both parts are rated for continuous operation from -55°C to 125°C. Applications requiring operation outside this range require alternative connector selection.
