Substitute Part Grouping Explanation

Substitute parts for the SFM-110-L3-L-D are identified based on strict equivalence of the following critical parameters:

• Connector type: Receptacle
• 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
• Contact finish - mating: Gold
• Current rating: 3.2A per contact
• Voltage rating: 250VAC
• Operating temperature: -55°C ~ 125°C
• Material flammability rating: UL94 V-0
• Insulation material: Liquid Crystal Polymer (LCP)
• Contact material: Beryllium copper
• RoHS status: ROHS3 Compliant

The substitute parts SFM-110-L3-L-D-A and SFM-110-03-L-D-A maintain all critical electrical and mechanical parameters. Differences in board guide features and moisture sensitivity level do not affect functional interchangeability for standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SFM-110-L3-L-D, SFM-110-L3-L-D-A, and SFM-110-03-L-D-A—are active products from Samtec Inc. and maintain ROHS3 compliance and EAR99 export classification. The parts are functionally equivalent for applications requiring 20-position, 0.050" pitch receptacle connectors with 3.2A per contact current capacity and 250VAC voltage rating.

SFM-110-L3-L-D-A and SFM-110-03-L-D-A include board guide features, which provide mechanical alignment assistance during mating. This feature does not affect electrical performance but may improve assembly reliability in applications with tight tolerance requirements.

Moisture sensitivity level differences (Not Applicable for SFM-110-L3-L-D and SFM-110-L3-L-D-A versus MSL 1 for SFM-110-03-L-D-A) do not impact functional interchangeability. All parts are suitable for standard storage and handling conditions.

Selection among these parts should be based on inventory availability, board guide requirement, and design preference. All parts meet identical electrical and mechanical specifications for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can SFM-110-L3-L-D-A be used as a direct replacement for SFM-110-L3-L-D?

A: Yes. Both parts are electrically and mechanically equivalent. The primary difference is the addition of a board guide feature in the SFM-110-L3-L-D-A variant, which does not affect functional interchangeability.

Q: What is the significance of the board guide feature in SFM-110-L3-L-D-A and SFM-110-03-L-D-A?

A: The board guide provides mechanical alignment assistance during connector mating. This feature improves assembly reliability but does not alter electrical performance or contact specifications.

Q: Are there differences in moisture sensitivity between these parts?

A: SFM-110-L3-L-D and SFM-110-L3-L-D-A are listed as Not Applicable for moisture sensitivity level, while SFM-110-03-L-D-A is rated MSL 1 (Unlimited). This difference does not affect functional performance or standard handling procedures.

Q: Do all three parts meet RoHS compliance?

A: Yes. All three parts are ROHS3 compliant and carry EAR99 export classification.

Q: What is the current rating per contact for these connectors?

A: All three parts are rated for 3.2A per contact at 250VAC, with operating temperature range of -55°C to 125°C.

Q: Are these parts suitable for board-to-board and cable applications?

A: Yes. All three parts are classified as board-to-board or cable style connectors with through-hole solder termination and push-pull fastening.

Q: Which part should be selected if inventory is a consideration?

A: SFM-110-03-L-D-A has the highest inventory availability at 2054 units, followed by SFM-110-L3-L-D-A at 1193 units, and SFM-110-L3-L-D at 1112 units. All are suitable for immediate procurement.
