Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFM-120-02-L-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: 40 positions at 0.050" (1.27mm) mating pitch with 2-row configuration
• Mounting & Termination: Surface mount with solder termination
• Electrical Ratings: 3.2A per contact at 250VAC
• Environmental Compliance: UL94 V-0 flammability rating, ROHS3 compliance, MSL 1
• Operating Temperature: -55°C ~ 125°C range
• Contact Material & Finish: Beryllium copper with gold mating finish (10.0µin thickness) and tin post finish

The identified substitute parts SFM-120-02-L-D-A-K and SFM-120-L2-L-D-A-K maintain identical electrical, mechanical, and environmental specifications across all critical parameters. Differences in part numbering reflect variations in contact post finish or internal design revisions that do not affect functional interchangeability in applications requiring the specified electrical and thermal performance.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—SFM-120-02-L-D-A-P, SFM-120-02-L-D-A-K, and SFM-120-L2-L-D-A-K—are active production parts with ROHS3 compliance and identical electrical and mechanical specifications. Selection between these equivalents should be based on:

Inventory Availability: SFM-120-02-L-D-A-K and SFM-120-L2-L-D-A-K maintain higher stock levels (869 and 833 units respectively) compared to SFM-120-02-L-D-A-P (657 units), supporting procurement continuity for high-volume applications.

Compliance & Certification: All three parts meet UL94 V-0 flammability requirements, ROHS3 compliance, and MSL 1 moisture sensitivity specifications, ensuring compatibility with regulated and industrial applications.

Functional Interchangeability: The identical electrical ratings (3.2A per contact, 250VAC), operating temperature range (-55°C ~ 125°C), and mechanical configuration (40-position, 0.050" pitch, surface mount) confirm direct substitution capability without design modification.

Frequently Asked Questions (FAQ)

Q: Can SFM-120-02-L-D-A-K and SFM-120-L2-L-D-A-K be used interchangeably with SFM-120-02-L-D-A-P?

A: Yes. All three part numbers share identical electrical ratings, mechanical dimensions, pitch specifications, and environmental compliance certifications. The differences in part numbering do not affect functional performance in applications requiring 40-position, 0.050" pitch receptacle connectors with 3.2A per contact capacity.

Q: What determines substitution eligibility for this connector series?

A: Substitution is valid when the following parameters remain constant: connector type (receptacle), contact configuration (female socket), position count (40), mating pitch (0.050"), row configuration (2 rows), mounting method (surface mount), termination type (solder), electrical ratings (3.2A, 250VAC), operating temperature range (-55°C ~ 125°C), and compliance certifications (UL94 V-0, ROHS3, MSL 1).

Q: Are there any packaging or handling differences between these part numbers?

A: All three parts are supplied in tube packaging with MSL 1 (unlimited moisture sensitivity level), indicating no special storage or handling requirements beyond standard component handling practices.

Q: What is the significance of the different part number suffixes?

A: The suffixes reflect internal design variations or contact post finish specifications that do not impact the mating interface, electrical performance, or mechanical compatibility. All variants maintain the same gold mating contact finish (10.0µin thickness) and tin post finish.

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

A: Yes. All three part numbers are rated for continuous operation across the -55°C ~ 125°C temperature range, supporting industrial and automotive applications within this thermal envelope.
