Key Parameters

Substitute Part Grouping Explanation

Substitution within the SFC-110 base product family is determined by the following critical parameters that must remain constant:

• 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 (Surface Mount)
• Contact type (Female Socket)
• Contact finish - mating (Gold)
• Current rating (3.1A per Contact)
• Voltage rating (350VAC)
• Operating temperature range (-55°C ~ 125°C)
• RoHS compliance (ROHS3)

The SFC-110-T2-LM-D-A and SFC-110-T2-L-D-A are both members of the Tiger Eye™ SFC series and share identical electrical and mechanical specifications. The difference in part number designation reflects internal manufacturing or packaging variations that do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SFC-110-T2-LM-D-A and SFC-110-T2-L-D-A are Active status products from Samtec Inc. and maintain full ROHS3 compliance with MSL 1 rating. Selection between these parts should be based on inventory availability and supply chain requirements, as all electrical and mechanical parameters are identical.

The SFC-110-T2-L-D-A currently maintains higher inventory levels (2385 Pcs) compared to the SFC-110-T2-LM-D-A (686 Pcs), making it suitable for high-volume production requirements or extended lead time mitigation.

Frequently Asked Questions (FAQ)

Q: Are SFC-110-T2-LM-D-A and SFC-110-T2-L-D-A electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 3.1A per contact current rating, 350VAC voltage rating, and gold-plated contact finish. They are direct functional equivalents within the SFC-110 base product family.

Q: What determines compatibility between these substitute parts?

A: Compatibility is determined by matching connector type (Receptacle), position count (20), mating pitch (0.050"), row configuration (2 rows at 0.050" spacing), mounting type (Surface Mount), contact type (Female Socket), and contact finish (Gold). Both parts meet these criteria identically.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. Both parts are surface mount receptacles with identical footprint requirements, pitch specifications, and mechanical dimensions. No PCB redesign is necessary for substitution.

Q: What is the significance of the part number suffix difference?

A: The part number designations reflect internal manufacturing or packaging variations within Samtec's product line. These variations do not affect electrical performance, mechanical compatibility, or functional operation.

Q: Are both parts suitable for high-reliability applications?

A: Both parts are Active status products with ROHS3 compliance and MSL 1 rating. Selection should be based on specific application requirements and supply chain considerations rather than reliability differences, as both maintain identical compliance certifications.
