Key Parameters

Substitute Part Grouping Explanation

The SFMC-102-01-S-D is identified as a direct substitute based on the following critical parameters that determine functional interchangeability:

• Connector Type: Receptacle
• Number of Positions: 4
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Through Hole
• Termination: Solder
• Contact Finish - Mating: Gold
• Current Rating: 2.9A per Contact
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• Insulation Material: Liquid Crystal Polymer (LCP)
• Contact Material: Beryllium Copper
• Base Product Number: SFMC-102

Both parts belong to the same Tiger Eye™ SFMC series and share identical electrical and mechanical specifications. The substitution is valid for applications requiring equivalent connector performance and form factor.

Parameter Comparison

Engineering Selection Recommendations

Both SFMC-102-01-SM-D and SFMC-102-01-S-D are active production parts from Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on inventory availability and moisture sensitivity requirements. The SFMC-102-01-S-D offers higher current inventory levels (1479 units versus 1137 units) and specifies an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints. The SFMC-102-01-SM-D lists MSL as Not Applicable. Both parts maintain identical electrical performance, mechanical dimensions, and environmental operating specifications, making them functionally equivalent for board-to-board and cable connector applications within the specified temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Are SFMC-102-01-SM-D and SFMC-102-01-S-D electrically interchangeable?

A: Yes. Both parts are rated for 2.9A per contact, operate across -55°C to 125°C, and feature identical gold-plated mating contacts with 30.0µin (0.76µm) thickness. They are electrically equivalent for all standard applications.

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

A: The primary differences are inventory availability and moisture sensitivity level designation. SFMC-102-01-S-D has higher stock (1479 units) and specifies MSL 1 (Unlimited), while SFMC-102-01-SM-D lists MSL as Not Applicable. All other electrical and mechanical parameters are identical.

Q: Can I use SFMC-102-01-S-D as a direct replacement for SFMC-102-01-SM-D in existing designs?

A: Yes. Both parts share the same connector type, position count, pitch, mounting method, and termination. PCB layouts and mating connector specifications require no modification.

Q: Are both parts RoHS compliant?

A: Yes. Both SFMC-102-01-SM-D and SFMC-102-01-S-D are ROHS3 compliant and carry EAR99 export classification.

Q: What is the through-hole pitch for these connectors?

A: Both parts feature a 0.050" (1.27mm) mating pitch with 2 rows spaced 0.050" (1.27mm) apart, accommodating standard PCB layouts for this connector family.
