Molex 0524372672 FFC/FPC Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0524372672 is a 26-position FFC/FPC connector from the Easy-On 52437 series, designed for surface mount, right-angle applications with bottom contact configuration. This connector operates at 50V with a 0.5A current rating and supports 0.50mm pitch flat flexible cable termination. The part is Active status and widely used in consumer electronics, computing peripherals, and industrial control applications requiring reliable zero insertion force (ZIF) connectivity.

Substitute parts are identified when design requirements change, inventory constraints occur, or alternative sourcing becomes necessary while maintaining electrical and mechanical compatibility within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0524372672 and 0524372671 are Active status products with full ROHS3 compliance and UL94 V-0 flammability certification, ensuring regulatory compliance for industrial and consumer applications.

The primary differentiation between these parts lies in three allowable variations:

Locking Mechanism: The main part uses Flip Lock actuation, while the substitute employs Slide Lock. Both mechanisms provide equivalent zero insertion force (ZIF) functionality and secure cable retention. Selection depends on available PCB space and operator preference for actuation style.

Cable End Configuration: The main part accommodates straight cable ends, while the substitute accepts both straight and tapered configurations. This variation provides design flexibility for applications requiring cable strain relief or specific connector geometry.

Contact Finish Material: The main part features Tin Bismuth contacts, while the substitute uses Gold plating. Gold contacts provide enhanced corrosion resistance and lower contact resistance in low-signal applications, though both finishes meet the 50V/0.5A electrical specification.

Both parts maintain identical electrical ratings (50V, 0.5A), operating temperature range (-40°C to 85°C), and mechanical specifications (26 positions, 0.50mm pitch, surface mount right angle). Selection between these parts should be based on specific application requirements regarding locking style, cable configuration compatibility, and contact finish performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0524372671 directly replace the 0524372672 in existing designs?

A: Yes, the 0524372671 is electrically and mechanically compatible as a substitute. The connector maintains identical position count (26), pitch (0.50mm), voltage/current ratings (50V/0.5A), and operating temperature range (-40°C to 85°C). Design verification is required only if the application has specific requirements for locking mechanism style or cable end geometry.

Q: What is the difference between Flip Lock and Slide Lock actuators?

A: Both locking mechanisms provide zero insertion force (ZIF) cable retention. Flip Lock uses a hinged actuator that rotates to secure the cable, while Slide Lock employs a linear sliding motion. The choice depends on PCB layout constraints and operator ergonomics. Both provide equivalent mechanical security and mating cycle performance (20 cycles minimum).

Q: Does the Gold contact finish of the 0524372671 affect electrical performance compared to Tin Bismuth?

A: Both contact finishes meet the specified 50V/0.5A electrical requirements. Gold plating provides superior corrosion resistance and lower contact resistance, particularly beneficial in humid environments or low-signal applications. Tin Bismuth contacts are suitable for standard industrial applications. Selection should consider environmental exposure and signal integrity requirements.

Q: Are both parts suitable for high-temperature applications?

A: Yes, both the 0524372672 and 0524372671 operate across the identical temperature range of -40°C to 85°C. Both are rated for this full range without derating. Applications requiring operation beyond 85°C require alternative connector selection.

Q: What is the significance of the tapered cable end option on the 0524372671?

A: The tapered cable end configuration on the 0524372671 provides improved strain relief and cable guidance during insertion. The main part (0524372672) accepts straight cable ends only. If the application requires tapered cable geometry for mechanical support or strain relief, the 0524372671 is the appropriate selection.

Q: Are both parts RoHS compliant?

A: Yes, both the Molex 0524372672 and 0524372671 are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting regulatory requirements for consumer electronics and industrial applications.

Q: What is the packaging format for these connectors?

A: Both parts are supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes. The main part has 1005 pieces in stock, while the substitute has 4075 pieces available.
