Substitute Part Grouping Explanation

Substitution for the SFM-140-L2-S-D-A-P is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 80 positions at 0.050" (1.27mm) mating pitch
• Row Configuration: 2 rows with 0.050" (1.27mm) row spacing
• Mounting & Termination: Surface mount with solder termination
• Electrical Performance: 3.2A per contact at 250VAC
• Environmental Compliance: Operating temperature range -55°C ~ 125°C, UL94 V-0, ROHS3 Compliant
• Fastening & Features: Push-pull fastening with board guide and pick-and-place capability

The substitute part SFM-140-02-S-D-A-P meets all these criteria and belongs to the same Tiger Eye™ SFM series from Samtec Inc.

Parameter Comparison

Engineering Selection Recommendations

Both the SFM-140-L2-S-D-A-P and SFM-140-02-S-D-A-P are active production parts from Samtec Inc. with identical electrical, mechanical, and environmental specifications. Both parts are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications. Selection between these parts may be based on inventory availability, lead time, or supply chain considerations, as they are functionally equivalent for all specified applications.

Frequently Asked Questions (FAQ)

Q: Are SFM-140-L2-S-D-A-P and SFM-140-02-S-D-A-P directly interchangeable?

A: Yes. Both parts are 80-position receptacle connectors with identical mating pitch (0.050"), row configuration, surface mount termination, and electrical ratings (3.2A per contact, 250VAC). They share the same contact material, finish specifications, and environmental operating range.

Q: What determines substitution eligibility for this connector series?

A: Substitution is valid when the following parameters match: connector type (receptacle), contact type (female socket), position count (80), mating pitch (0.050"), row count and spacing (2 rows at 0.050"), mounting type (surface mount), fastening mechanism (push-pull), contact finish (gold), and electrical ratings (3.2A, 250VAC).

Q: Do these parts have different mated stacking heights?

A: Both parts support the same mated stacking height options: 6.15mm, 6.30mm, 7.92mm, 8.08mm, 9.70mm, 9.86mm, 11.61mm, and 11.76mm.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, carry UL94 V-0 flammability rating, and have MSL 1 (unlimited moisture sensitivity level).

Q: What is the difference between the part numbers?

A: The part numbers differ in their internal designation codes (L2 versus 02), but these variations do not affect electrical performance, mechanical compatibility, or environmental specifications for the specified application parameters.
