Substitute Part Grouping Explanation

Substitute parts for the SFM-135-02-SM-D-A are identified based on strict equivalence of the following critical parameters:

• Connector type: Receptacle
• Number of positions: 70
• Pitch - mating: 0.050" (1.27mm)
• Number of rows: 2
• Row spacing - mating: 0.050" (1.27mm)
• Mounting type: Surface Mount
• 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)
• Base product number: SFM-135

The identified substitutes differ only in fastening mechanism designation within the part number nomenclature (SM vs. S designation), while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status within the Tiger Eye™ SFM series and are ROHS3 compliant with identical electrical and mechanical specifications. Selection between SFM-135-02-SM-D-A, SFM-135-02-S-D-A, and SFM-135-L2-S-D-A is determined by inventory availability and fastening mechanism requirements as specified in the part number nomenclature. All parts carry EAR99 export classification and are suitable for applications requiring 250VAC, 3.2A per contact operation across the -55°C to 125°C temperature range.

Frequently Asked Questions (FAQ)

Q: Are SFM-135-02-SM-D-A, SFM-135-02-S-D-A, and SFM-135-L2-S-D-A electrically interchangeable?

A: Yes. All three parts share identical electrical specifications including 3.2A per contact current rating, 250VAC voltage rating, gold-plated mating contacts, and operating temperature range of -55°C to 125°C.

Q: What is the difference between the part numbers?

A: The differences are reflected in the part number designations (SM vs. S, and L2 vs. standard). These designations correspond to fastening mechanism variations within the same connector family while maintaining full compatibility with 70-position, 0.050" pitch receptacle applications.

Q: Are all three parts surface mount compatible?

A: Yes. All three parts are specified for surface mount termination with identical mating pitch and row spacing of 0.050" (1.27mm).

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, carry UL94 V-0 material flammability rating, and have moisture sensitivity level 1 (unlimited). All are classified as EAR99 for export purposes.

Q: Which part should be selected based on availability?

A: Selection can be based on inventory levels: SFM-135-02-S-D-A has 1246 units in stock, SFM-135-L2-S-D-A has 1140 units, and SFM-135-02-SM-D-A has 976 units available. All are functionally equivalent for the specified application.
