Molex 0527450796 FFC/FPC Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0527450796 is a 7-position FFC/FPC connector from the Easy-On 52745 series, designed for surface mount, right-angle applications with 0.50mm pitch contacts. This connector features zero insertion force (ZIF) operation, slide lock retention, and tin bismuth contact finish. The part is active in production with 677 units currently in stock.

Substitute parts are identified when they maintain electrical and mechanical compatibility across critical parameters including connector position count, pitch spacing, mounting orientation, termination method, voltage and current ratings, operating temperature range, and locking mechanism. Identifying equivalent components ensures design flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0527450796 is determined by strict equivalence across the following critical parameters:

• Connector Position Count: 7 positions (fixed requirement)
• Pitch Spacing: 0.020" (0.50mm) (fixed requirement)
• Mounting Configuration: Surface mount, right-angle orientation (fixed requirement)
• Connector/Contact Type: Contacts, top-mounted (fixed requirement)
• Termination Method: Solder termination (fixed requirement)
• Electrical Ratings: Minimum 50V voltage rating and 0.5A current rating (fixed requirement)
• Operating Temperature Range: -20°C to 85°C (fixed requirement)
• Locking Mechanism: Slide lock retention (fixed requirement)
• Product Status: Active production status (preferred)
• Compliance: ROHS3 compliance (preferred)

Substitute parts must match all fixed requirements. Variations in contact finish material, housing color, actuator material, or cable end type do not disqualify substitution when all electrical and mechanical parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0527450797 is a direct substitute for the 0527450796 based on equivalence across all critical electrical and mechanical parameters. Both parts are active production items with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications.

The primary difference between these parts is the contact finish: the main part uses tin bismuth finish, while the substitute uses gold finish. Both finishes are compatible with solder termination and maintain the same electrical performance within the specified voltage and current ratings. The gold finish on the substitute may provide enhanced corrosion resistance in certain environmental conditions.

Both connectors support the same 7-position, 0.50mm pitch configuration with identical mechanical dimensions, mounting orientation, and locking mechanism. Selection between these parts may be based on inventory availability, cost considerations, or specific environmental requirements where contact finish material is a design factor.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0527450797 be used as a direct replacement for the 0527450796 in existing designs?

A: Yes. The 0527450797 maintains electrical and mechanical equivalence across all critical parameters including position count, pitch, mounting type, voltage rating, current rating, operating temperature range, and locking mechanism. Both parts are from the same Easy-On 52745 series and support identical PCB footprints and mating interfaces.

Q: What is the difference between tin bismuth and gold contact finishes?

A: Tin bismuth and gold are both acceptable contact finish materials for solder-terminated connectors. Gold provides enhanced corrosion resistance and is typically specified for applications requiring extended shelf life or exposure to corrosive environments. Tin bismuth is suitable for standard industrial applications. Both finishes maintain equivalent electrical conductivity and solderability.

Q: Are the PCB footprints identical between these two parts?

A: Yes. Both the 0527450796 and 0527450797 share identical mechanical dimensions, including height above board (0.079" / 2.00mm), pitch spacing (0.020" / 0.50mm), and mounting configuration. No PCB redesign is required when substituting between these parts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 material flammability ratings. They are suitable for applications requiring regulatory compliance in industrial and consumer electronics markets.

Q: What is the inventory status for each part?

A: The main part (0527450796) has 677 units in stock. The substitute part (0527450797) has 8315 units in stock, providing greater availability for immediate procurement needs.
