Key Parameters

Substitute Part Grouping Explanation

Substitution within the SFM-135 series is determined by electrical and mechanical compatibility. All listed substitute parts maintain identical core specifications: 70-position receptacle configuration, 0.050" pitch, surface mount solder termination, gold mating contact finish, 3.2A current rating, and 250VAC voltage rating. The primary differentiators among substitute parts are mounting features (Board Guide, Board Lock, Pick and Place) and contact finish post material options. These variations do not affect electrical performance or mating compatibility but address specific assembly and handling requirements.

Key parameters determining substitution eligibility:

• Number of positions: 70
• Pitch specification: 0.050" (1.27mm)
• Connector type: Receptacle
• Mounting type: Surface Mount
• Contact finish - Mating: Gold
• Current and voltage ratings: 3.2A / 250VAC

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are Active status products from Samtec Inc. and maintain ROHS3 compliance with MSL 1 (Unlimited) rating. Selection among equivalent parts should be based on assembly process requirements:

• SFM-135-L2-S-D and SFM-135-02-S-D-A: Use when board guide feature is required for alignment during assembly.
• SFM-135-L2-S-D-LC, SFM-135-02-S-D-LC, and SFM-135-02-S-D-LC-P: Use when board lock feature is required for mechanical retention.
• SFM-135-02-S-D-LC-P: Use when automated pick-and-place assembly is specified.

All parts share identical electrical performance characteristics and are mechanically interchangeable within their respective feature categories. Inventory availability should be considered for procurement planning.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts electrically interchangeable with SFM-135-L2-S-D?

A: Yes. All substitute parts maintain identical electrical specifications: 70 positions, 0.050" pitch, 3.2A per contact rating, and 250VAC voltage rating. Mating contact finish and post finish are consistent across all variants.

Q: What is the difference between Board Guide and Board Lock features?

A: Board Guide provides alignment assistance during connector mating. Board Lock provides mechanical retention after mating. These are mounting feature variations that do not affect electrical performance or contact compatibility.

Q: Can SFM-135-02-S-D-LC-P be used in manual assembly processes?

A: Yes. The Pick and Place feature is an assembly aid for automated equipment but does not prevent manual assembly. The connector functions identically to other variants in the series.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What determines which substitute part to select?

A: Selection is based on assembly process requirements (board guide vs. board lock vs. pick and place capability) and inventory availability. Electrical and mechanical specifications are identical across all variants.
