Key Parameters

Substitute Part Grouping Explanation

The SFMC-117-02-S-D qualifies as a direct substitute based on the following critical parameters:

• Connector Type & Position Count: Both are 34-position receptacles within the Tiger Eye™ SFMC series
• Pitch & Row Configuration: Identical 0.050" (1.27mm) mating pitch and 2-row layout with 0.050" row spacing
• Mounting & Termination: Both use surface mount with solder termination and push-pull fastening
• Contact Specifications: Both feature female socket contacts with gold mating finish (30.0µin thickness) and tin post finish
• Electrical Performance: Both rated at 2.9A per contact
• Environmental & Compliance: Both operate across -55°C to 125°C, meet UL94 V-0 flammability, ROHS3 compliance, and MSL 1 (Unlimited)
• Insulation Material: Both use Liquid Crystal Polymer (LCP) with black insulation and 0.185" (4.70mm) height

The primary difference is the contact material: SFMC-117-T2-S-D uses Phosphor Bronze, while SFMC-117-02-S-D uses Beryllium Copper. Both materials are acceptable for the specified electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

Both SFMC-117-T2-S-D and SFMC-117-02-S-D are active production parts with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory Availability: SFMC-117-02-S-D has higher stock (1188 units vs. 800 units), supporting supply chain continuity
• Contact Material Specification: Verify design requirements for contact material. Phosphor Bronze (SFMC-117-T2-S-D) and Beryllium Copper (SFMC-117-02-S-D) both meet the stated electrical and mechanical parameters
• Compliance Requirements: Both parts meet identical compliance standards (ROHS3, UL94 V-0, MSL 1)

Both parts are suitable for direct substitution in applications requiring 34-position, 0.050" pitch surface mount receptacle connectors with gold mating contacts and 2.9A per contact current rating.

Frequently Asked Questions (FAQ)

Q: Can SFMC-117-02-S-D replace SFMC-117-T2-S-D in existing designs?

A: Yes. Both connectors share identical electrical and mechanical specifications including position count, pitch, mounting type, current rating, and operating temperature range. The contact material differs (Beryllium Copper vs. Phosphor Bronze), but both materials meet the specified performance requirements.

Q: What is the difference between these two part numbers?

A: The primary difference is the contact material. SFMC-117-T2-S-D uses Phosphor Bronze contacts, while SFMC-117-02-S-D uses Beryllium Copper contacts. All other specifications—pitch, position count, current rating, temperature range, and compliance certifications—are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both SFMC-117-T2-S-D and SFMC-117-02-S-D are ROHS3 compliant and meet UL94 V-0 flammability requirements.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can these connectors be used interchangeably on the same PCB?

A: Yes. Both connectors have identical footprints, pitch spacing (0.050"), row configuration, and surface mount termination, allowing direct PCB layout compatibility.

Q: What is the current rating per contact?

A: Both connectors are rated at 2.9A per contact across the full operating temperature range of -55°C to 125°C.
