Key Parameters

Substitute Part Grouping Explanation

Substitution within the Tiger Eye™ SFML series is determined by strict equivalence across the following critical parameters:

• 80-position receptacle configuration with 2-row layout
• 0.050" (1.27mm) pitch mating and row spacing
• Surface mount solder termination with locking ramp fastening
• Gold contact finish (30.0µin thickness) with tin post finish
• 3.2A per contact current rating at 250VAC
• Operating temperature range of -55°C ~ 125°C
• UL94 V-0 flammability rating and LCP insulation material
• ROHS3 compliance and MSL 1 rating

The SFML-140-02-S-D is designated as the manufacturer-recommended substitute and maintains identical electrical, mechanical, and environmental specifications as the SFML-140-T2-S-D within the same product series.

Parameter Comparison

Engineering Selection Recommendations

Both the SFML-140-T2-S-D and SFML-140-02-S-D are Active products with full compliance to ROHS3 and REACH requirements. Selection between these parts should be based on:

• Inventory availability and procurement lead times
• Supplier stock levels (SFML-140-T2-S-D: 964 pcs; SFML-140-02-S-D: 1078 pcs)
• Design documentation and part number traceability requirements
• Cost considerations within the same product series

Both connectors satisfy identical electrical performance specifications, mechanical interface requirements, and environmental operating conditions. No functional differences exist between these parts within the Tiger Eye™ SFML series.

Frequently Asked Questions (FAQ)

Q: Are SFML-140-T2-S-D and SFML-140-02-S-D electrically interchangeable?

A: Yes. Both parts are 80-position receptacle connectors with identical electrical ratings (3.2A per contact, 250VAC), operating temperature range (-55°C ~ 125°C), and contact finish specifications (gold mating, tin post).

Q: Do these connectors have the same mechanical footprint?

A: Yes. Both connectors feature identical pitch (0.050"), row spacing (0.050"), mounting type (surface mount), and insulation height (0.185"). They are mechanically compatible for board-to-board and cable applications.

Q: What determines substitution eligibility within the Tiger Eye™ SFML series?

A: Substitution is valid when the following parameters match: connector type (receptacle), position count (80), pitch and row spacing (0.050"), mounting method (surface mount), termination type (solder), current and voltage ratings, operating temperature range, contact finish specifications, and flammability rating (UL94 V-0).

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. They meet identical regulatory and environmental standards.

Q: Can I use SFML-140-02-S-D as a direct replacement in existing designs?

A: Yes. The SFML-140-02-S-D is the manufacturer-recommended substitute and maintains full compatibility with designs specified for SFML-140-T2-S-D across all electrical, mechanical, and environmental parameters.
