Key Parameters

Substitute Part Grouping Explanation

Substitution of the SFM-110-02-SM-D-A-P is based on strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Position count (20 positions)
• Mating pitch (0.050" / 1.27mm)
• Row configuration (2 rows with 0.050" spacing)
• Mounting technology (Surface Mount)
• Contact finish (Gold mating surface)
• Electrical ratings (3.2A per contact, 250VAC)
• Operating temperature range (-55°C ~ 125°C)
• Flammability compliance (UL94 V-0)
• RoHS compliance (ROHS3)

The identified substitutes maintain all these parameters identically. Differences exist only in fastening mechanism designation codes within the part number suffix, which do not affect electrical or mechanical compatibility for board-level integration.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SFM-110-02-SM-D-A-P, SFM-110-02-S-D-A-P, and SFM-110-02-S-D-A-K—are Active status products from Samtec Inc. and maintain full compliance with ROHS3 and UL94 V-0 flammability requirements. They are electrically and mechanically interchangeable for board-level applications requiring 20-position, 0.050" pitch surface mount receptacle connectors.

Selection between these parts should be based on inventory availability and lead time requirements. SFM-110-02-S-D-A-K currently has the highest inventory level at 3826 pieces. All parts carry MSL 1 (Unlimited) moisture sensitivity classification and are suitable for standard PCB assembly processes without special handling.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable?

A: Yes. All three parts maintain identical electrical specifications: 3.2A per contact, 250VAC rating, gold-plated mating contacts with 30.0µin thickness, and operating temperature range of -55°C to 125°C.

Q: What is the difference between SFM-110-02-SM-D-A-P and SFM-110-02-S-D-A-P?

A: The parts differ only in the fastening mechanism designation code within the part number suffix. Both are push-pull receptacles with identical mechanical and electrical characteristics. The difference is encoded in the part number but does not affect board-level compatibility.

Q: Can I use SFM-110-02-S-D-A-K as a direct replacement?

A: Yes. SFM-110-02-S-D-A-K is a direct substitute with identical specifications across all critical parameters: connector type, position count, pitch, row configuration, mounting technology, contact finish, electrical ratings, temperature range, and compliance certifications.

Q: Are there any PCB layout considerations when switching between these parts?

A: No. All three parts share identical mating pitch (0.050"), row spacing (0.050"), insulation height (0.185"), and contact geometry. PCB footprints and assembly processes remain unchanged.

Q: What is the MSL rating for these connectors?

A: All parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard PCB assembly processes and storage conditions apply without special precautions.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and meet UL94 V-0 flammability requirements, suitable for applications with environmental and regulatory compliance mandates.
