Substitute Part Grouping Explanation

Substitution eligibility for the SFM-110-L2-S-D-A-TR is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Arrangement: 20 positions in 2-row configuration
• Pitch Specifications: 0.050" (1.27mm) mating pitch and row spacing
• Mounting & Termination: Surface mount with solder termination
• Electrical Performance: 3.2A per contact, 250VAC rating
• Environmental Compliance: UL94 V-0 flammability, ROHS3 compliance, MSL 1 rating
• Temperature Range: -55°C to 125°C operating window
• Contact Material & Finish: Beryllium copper with gold mating finish (30.0µin thickness) and tin post finish

The SFM-110-02-S-D-A-TR qualifies as a direct substitute based on identical alignment across all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the SFM-110-L2-S-D-A-TR and SFM-110-02-S-D-A-TR maintain Active product status within the Tiger Eye™ SFM series. Selection between these parts is based on inventory availability and supply chain requirements rather than functional or electrical differences. Both parts carry identical ROHS3 compliance certification, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification, ensuring equivalent performance in regulated and high-reliability applications. The SFM-110-02-S-D-A-TR currently maintains higher inventory levels (2659 pcs vs. 897 pcs), which may influence procurement decisions for volume production schedules.

Frequently Asked Questions (FAQ)

Q: Are SFM-110-L2-S-D-A-TR and SFM-110-02-S-D-A-TR electrically interchangeable?
