91763-104TRLF Equivalent & Substitute Parts

Part Overview

The 91763-104TRLF is a 4-position rectangular receptacle connector manufactured by Amphenol ICC (FCI) in the Minitek® series. This surface mount, bottom entry connector operates at 0.079" (2.00mm) pitch and is designed for board-to-board or cable applications. The part is currently active in production with 973 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to availability constraints, design flexibility, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 91763-104TRLF is determined by the following critical parameters:

• Connector Configuration: 4-position receptacle with 2 rows at 0.079" (2.00mm) pitch and row spacing
• Mounting and Termination: Surface mount with solder termination
• Electrical Performance: Operating temperature range of -55°C ~ 125°C and UL94 V-0 flammability rating
• Compliance: RoHS compliance status and MSL rating of 1 (Unlimited)
• Contact Interface: Female socket contacts with gold mating finish

The CLT-102-02-G-D meets these substitution criteria through equivalent mechanical pitch, position count, mounting type, operating temperature range, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 91763-104TRLF and CLT-102-02-G-D are active production parts with equivalent mechanical and electrical specifications. The 91763-104TRLF is RoHS Compliant, while the CLT-102-02-G-D carries ROHS3 Compliant status, indicating compliance with the most current RoHS directive. Both parts maintain UL94 V-0 flammability ratings and unlimited moisture sensitivity levels. The CLT-102-02-G-D provides higher current rating per contact (4.1A versus 1A) and uses Phosphor Bronze contacts with Liquid Crystal Polymer insulation, compared to the Beryllium Copper contacts and plastic insulation of the main part. Selection between these parts should be based on specific application current requirements and supply availability.

Frequently Asked Questions (FAQ)

Q: Can the CLT-102-02-G-D directly replace the 91763-104TRLF in existing designs?

A: The CLT-102-02-G-D shares identical pitch (0.079"), position count (4), row configuration (2 rows), mounting type (surface mount), and operating temperature range (-55°C ~ 125°C). Both use push-pull fastening and gold-plated female socket contacts. Physical footprint compatibility requires verification of insulation height (91763-104TRLF: 0.091", CLT-102-02-G-D: 0.083") and connector body dimensions against PCB layout constraints.

Q: What are the differences in contact material and finish?

A: The 91763-104TRLF uses Beryllium Copper contacts with 30.0µin (0.76µm) gold mating finish and flash post finish. The CLT-102-02-G-D uses Phosphor Bronze contacts with 10.0µin (0.25µm) gold mating finish and 3.00µin (0.076µm) post finish. Both provide gold mating interfaces suitable for standard connector applications.

Q: Are there compliance differences between these parts?

A: The 91763-104TRLF is RoHS Compliant, while the CLT-102-02-G-D is ROHS3 Compliant. Both are REACH affected or unaffected respectively, classified under ECCN EAR99, and share the same HTSUS code (8536.69.4040). Both maintain UL94 V-0 flammability ratings and MSL 1 (Unlimited) moisture sensitivity levels.

Q: What is the current rating difference?

A: The 91763-104TRLF is rated at 1A total current, while the CLT-102-02-G-D is rated at 4.1A per contact. Applications requiring higher current per contact should specify the CLT-102-02-G-D.

Q: How do packaging differences affect procurement?

A: The 91763-104TRLF is supplied in Tape & Reel (TR) packaging with 973 units in stock. The CLT-102-02-G-D is supplied in Bulk packaging with 737 units in stock. Packaging selection depends on assembly process requirements and volume needs.
