Key Parameters

Substitute Part Grouping Explanation

The SFM-110-L2-H-D-A has one identified substitute within the Tiger Eye™ SFM series: SFM-110-02-H-D-A. Substitution eligibility is determined by the following critical parameters that must remain identical:

• Connector type (Receptacle)
• Contact type (Female Socket)
• 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)
• Current rating (3.2A per Contact)
• Voltage rating (250VAC)
• Operating temperature range (-55°C ~ 125°C)
• Contact finish - mating (Gold)
• Material flammability rating (UL94 V-0)
• Insulation material (Liquid Crystal Polymer)
• RoHS compliance (ROHS3 Compliant)

Both parts share the same base product number (SFM-110) and are functionally equivalent for applications requiring these electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both SFM-110-L2-H-D-A and SFM-110-02-H-D-A are active production parts with ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and supply chain requirements. The SFM-110-02-H-D-A currently has higher stock levels (1041 units versus 705 units), which may support extended lead time requirements or volume production schedules. Both parts carry MSL 1 (Unlimited) moisture sensitivity classification, eliminating special storage or handling constraints.

Frequently Asked Questions (FAQ)

Q: Are SFM-110-L2-H-D-A and SFM-110-02-H-D-A electrically and mechanically interchangeable?

A: Yes. Both parts are 20-position receptacle connectors with identical pitch (0.050"), row spacing (0.050"), current rating (3.2A per contact), voltage rating (250VAC), operating temperature range (-55°C to 125°C), and contact finish specifications. They share the same base product number (SFM-110) and are functionally equivalent for board-to-board and cable applications.

Q: What determines substitution eligibility for these connectors?

A: Substitution is valid when the following parameters remain constant: connector type, contact type, number of positions, mating pitch, number of rows, row spacing, mounting type, current rating, voltage rating, operating temperature range, contact finish, and compliance certifications. Any deviation in these parameters requires re-evaluation of compatibility.

Q: Do both parts have the same RoHS and moisture sensitivity classifications?

A: Yes. Both SFM-110-L2-H-D-A and SFM-110-02-H-D-A are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, indicating no special storage or handling requirements.

Q: Can these connectors be used in high-temperature applications?

A: Both parts are rated for operating temperatures from -55°C to 125°C. Applications requiring operation outside this range are not supported by these connector specifications.

Q: What is the mated stacking height for these connectors?

A: Both parts support multiple mated stacking heights: 6.15mm, 6.30mm, 7.92mm, 8.08mm, 9.70mm, 9.86mm, 11.61mm, and 11.76mm, depending on the mating connector configuration.
