Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFM-120-L2-L-D-A is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (40)
• Pitch specification (0.050" / 1.27mm mating pitch)
• Row configuration (2 rows with 0.050" row spacing)
• Mounting method (Surface Mount)
• Contact finish (Gold mating surface)
• Current and voltage ratings (3.2A per contact, 250VAC)
• Operating temperature range (-55°C ~ 125°C)
• Material compliance (UL94 V-0, ROHS3 Compliant)

The identified substitute part SFM-120-02-L-D-A maintains full electrical and mechanical compatibility through identical specifications across all critical parameters. Both parts belong to the same Tiger Eye™ SFM series and share the same base product number (SFM-120), confirming their interchangeability within the connector family.

Parameter Comparison

Engineering Selection Recommendations

Both the SFM-120-L2-L-D-A and SFM-120-02-L-D-A are active production parts with full regulatory compliance. The SFM-120-02-L-D-A offers higher inventory availability (2000 pcs vs. 892 pcs), making it suitable for high-volume applications or extended supply chain requirements. Both parts carry identical ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification, confirming their suitability for equivalent applications. Selection between these parts should be based on inventory requirements and delivery timeline rather than electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Are SFM-120-L2-L-D-A and SFM-120-02-L-D-A fully interchangeable?

A: Yes. Both parts are identical across all electrical and mechanical parameters, including connector type, position count, pitch, row configuration, contact ratings, and operating specifications. They share the same base product number (SFM-120) within the Tiger Eye™ SFM series.

Q: What determines substitution eligibility for this connector?

A: Substitution requires matching specifications across connector type (receptacle), position count (40), mating pitch (0.050"), row configuration (2 rows at 0.050" spacing), mounting method (surface mount), contact finish (gold), current/voltage ratings (3.2A/250VAC), temperature range (-55°C to 125°C), and compliance certifications (ROHS3, UL94 V-0).

Q: Can I use these connectors in applications requiring different pitch or position counts?

A: No. These connectors are specifically designed for 40-position, 0.050" pitch applications. Different pitch or position requirements necessitate different connector models from the SFM series or alternative product families.

Q: Are there any packaging or delivery differences between these parts?

A: Both parts are supplied in tube packaging. The primary difference is inventory availability, with SFM-120-02-L-D-A offering higher stock levels.

Q: What is the significance of the base product number SFM-120?

A: The base product number SFM-120 identifies the core connector platform within Samtec's Tiger Eye™ SFM series. Variants of this base number (such as L2 and 02 designations) represent different configurations or manufacturing batches while maintaining core electrical and mechanical compatibility.
