Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SFM-110-L1-S-D are identified based on electrical and mechanical parameter equivalence within the Tiger Eye™ SFM series. The substitution criteria are strictly limited to the following 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)
• Contact finish - mating (Gold)
• Contact finish - post (Tin)
• Current rating (3.2A per Contact)
• Voltage rating (250VAC)
• Operating temperature range (-55°C ~ 125°C)
• Material flammability rating (UL94 V-0)
• RoHS compliance (ROHS3)

The identified substitutes SFM-110-01-S-D and SFM-110-01-S-D-A meet all core electrical and mechanical requirements. The SFM-110-01-S-D-A variant includes a board guide feature as an additional design element.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—SFM-110-L1-S-D, SFM-110-01-S-D, and SFM-110-01-S-D-A—are active products with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is based on design requirements and availability:

SFM-110-L1-S-D is the primary specification with the highest current inventory level (889 units). SFM-110-01-S-D provides direct electrical and mechanical equivalence with 765 units available. SFM-110-01-S-D-A includes a board guide feature and is suitable for applications requiring enhanced mechanical alignment during mating, with 705 units in stock.

All parts share identical electrical ratings, operating temperature range, contact materials, and compliance certifications. Selection should be based on mechanical design requirements and part availability at the time of procurement.

Frequently Asked Questions (FAQ)

Q: Are SFM-110-01-S-D and SFM-110-01-S-D-A electrically interchangeable with SFM-110-L1-S-D?

A: Yes. All three parts share identical electrical specifications including current rating (3.2A per contact), voltage rating (250VAC), contact materials (beryllium copper), and contact finishes (gold mating, tin post). They are electrically equivalent.

Q: What is the difference between SFM-110-01-S-D and SFM-110-01-S-D-A?

A: The SFM-110-01-S-D-A includes a board guide feature. Both parts are otherwise mechanically and electrically identical. The board guide provides additional mechanical alignment support during connector mating.

Q: Can these connectors be used in the same PCB footprint?

A: Yes. All three parts share identical pitch (0.050" / 1.27mm), row spacing (0.050" / 1.27mm), number of positions (20), number of rows (2), and through-hole mounting type. They are footprint-compatible.

Q: Are all parts RoHS compliant?

A: Yes. SFM-110-L1-S-D, SFM-110-01-S-D, and SFM-110-01-S-D-A are all ROHS3 compliant.

Q: What is the operating temperature range for these connectors?

A: All three parts operate across -55°C to 125°C.

Q: Which part should I select if I need the highest inventory availability?

A: SFM-110-L1-S-D has the highest inventory level at 889 units in stock.
