Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFMC-103-L1-L-D is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (6)
• Pitch - mating (0.050" / 1.27mm)
• Number of rows (2)
• Row spacing - mating (0.050" / 1.27mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Contact finish - mating (Gold)
• Contact finish thickness - mating (10.0µin / 0.25µm)
• Current rating (2.9A per Contact)
• Operating temperature range (-55°C ~ 125°C)
• Material flammability rating (UL94 V-0)
• Insulation material (Liquid Crystal Polymer)
• Contact material (Beryllium Copper)
• RoHS compliance (ROHS3 Compliant)

The SFMC-103-01-L-D meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the SFMC-103-L1-L-D and SFMC-103-01-L-D are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Both parts are ROHS3 compliant and carry the same UL94 V-0 flammability rating, meeting equivalent regulatory requirements.

The SFMC-103-01-L-D offers higher inventory availability (1274 units versus 602 units), making it suitable for applications requiring extended supply assurance. Both parts are functionally interchangeable for board-to-board and cable connector applications within the specified operating temperature range of -55°C to 125°C and current rating of 2.9A per contact.

Frequently Asked Questions (FAQ)

Q: Are SFMC-103-L1-L-D and SFMC-103-01-L-D mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 0.050" (1.27mm) pitch, 6-position configuration, 2-row layout, through-hole mounting, and push-pull fastening. PCB footprints and mating interfaces are identical.

Q: Are these parts electrically equivalent?

A: Yes. Both parts have identical current ratings (2.9A per contact), operating temperature range (-55°C to 125°C), contact materials (Beryllium Copper), and contact finishes (Gold at 10.0µin thickness).

Q: What is the difference between these two part numbers?

A: The primary differences are inventory levels and moisture sensitivity level designation. The SFMC-103-01-L-D has higher stock availability and is designated MSL 1 (Unlimited), while the SFMC-103-L1-L-D is listed as Not Applicable for MSL.

Q: Can I substitute SFMC-103-01-L-D for SFMC-103-L1-L-D in existing designs?

A: Yes. The parts are direct equivalents with identical electrical, mechanical, and environmental specifications. No design modifications are required.

Q: Are both parts RoHS compliant?

A: Yes. Both SFMC-103-L1-L-D and SFMC-103-01-L-D are ROHS3 compliant.

Q: What is the solder termination type for these connectors?

A: Both connectors use solder termination for through-hole PCB mounting. Contact posts are tin-finished for soldering.
