Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SFMC-110-L3-S-D are identified based on strict equivalence across the following critical parameters:

• Number of Positions: 20
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Through Hole
• Termination: Solder
• Connector Type: Receptacle
• Contact Type: Female Socket
• Contact Finish - Mating: Gold
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Insulation Material: Liquid Crystal Polymer (LCP)
• Contact Material: Beryllium Copper

All identified substitutes maintain identical electrical and mechanical specifications within these parameters. Variations in packaging options, inventory levels, or manufacturing codes do not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SFMC-110-L3-S-D, SFMC-110-03-S-D, and SFMC-110-L3-S-D-P—are active products from Samtec Inc. and maintain full compliance with ROHS3 and REACH requirements. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Specific packaging or handling requirements (SFMC-110-L3-S-D-P includes Pick and Place feature)
• Moisture sensitivity considerations for storage and handling environments

All parts are electrically and mechanically interchangeable for applications requiring 20-position, 0.050" pitch receptacle connectors with gold-plated mating contacts and through-hole solder termination.

Frequently Asked Questions (FAQ)

Q: Are SFMC-110-L3-S-D, SFMC-110-03-S-D, and SFMC-110-L3-S-D-P fully interchangeable?

A: Yes. All three parts share identical electrical and mechanical specifications including connector type, position count, pitch, row spacing, mounting type, termination method, contact finish, current rating, and operating temperature range. They are functionally equivalent for board-to-board and cable applications.

Q: What is the difference between SFMC-110-L3-S-D-P and the other variants?

A: SFMC-110-L3-S-D-P includes a Pick and Place feature and has a Moisture Sensitivity Level (MSL) designation of Not Applicable, compared to MSL 1 (Unlimited) for the other variants. This indicates different handling and storage requirements.

Q: Can I substitute SFMC-110-03-S-D for SFMC-110-L3-S-D in my design?

A: Yes. Both parts are identical in all critical parameters: 20 positions, 0.050" pitch, 2 rows, through-hole mounting, solder termination, gold mating contacts, and operating temperature range of -55°C to 125°C.

Q: What are the key parameters that determine substitutability for this connector family?

A: Substitutability is determined by: number of positions (20), mating pitch (0.050"), row count (2), row spacing (0.050"), mounting type (through hole), termination method (solder), contact finish (gold), and operating temperature range (-55°C to 125°C).

Q: Are there any compliance differences between these parts?

A: All three parts are ROHS3 compliant and REACH unaffected. The primary difference is the MSL designation: SFMC-110-L3-S-D and SFMC-110-03-S-D are MSL 1 (Unlimited), while SFMC-110-L3-S-D-P is Not Applicable.
