Molex 0526100733 FPC Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0526100733 is a 7-position vertical FPC connector with 1.00mm pitch, designed for surface mount applications. This connector features Zero Insertion Force (ZIF) operation with slide lock actuation and is rated for 125V at 1A per contact. The part is currently obsolete, making equivalent substitutes necessary for ongoing design support and component sourcing.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0526100733 is determined by strict alignment with the following critical parameters:

7-position configuration with 1.00mm pitch spacing
Vertical orientation with single-sided contact arrangement
Surface mount termination via solder
Slide lock actuation mechanism
Zero Insertion Force (ZIF) operation
125V voltage rating and 1A current capacity
UL94 V-0 flammability compliance
Solder termination method

The identified substitutes meet these core electrical and mechanical requirements. Variations in housing material composition, contact finish type, and height above board are within acceptable tolerance ranges for this connector category and do not affect functional interchangeability in standard applications.

Engineering Selection Recommendations

Molex 0526100771 is the manufacturer-recommended direct substitute. As an active product within the same Easy-On 52610 series, it maintains identical electrical specifications, pitch, position count, and mounting characteristics. Both parts share ROHS3 compliance and identical voltage/current ratings. The transition from Cut Tape to Tape & Reel packaging reflects standard production evolution without affecting component functionality.

TE Connectivity 1734248-7 provides an alternative from a different manufacturer. This part meets all core electrical and mechanical requirements with equivalent ZIF operation and slide lock actuation. The TE part operates across a narrower temperature range (-20°C to 85°C versus -40°C to 85°C) and supports 20 mating cycles compared to 30 for the Molex alternatives. Height above board is 0.217" (5.50mm) versus 0.226" (5.74mm) for Molex parts, a 0.24mm difference within standard PCB layout tolerances. Contact finish is gold rather than tin bismuth, providing enhanced corrosion resistance in certain environments.

Selection between active substitutes depends on supply chain availability, packaging requirements, and specific application temperature or mating cycle demands.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0526100771 directly replace the obsolete 0526100733?

A: Yes. Both parts are from the same Easy-On 52610 series with identical electrical ratings, pitch, position count, and mounting type. The primary difference is packaging format (Cut Tape versus Tape & Reel) and product status transition from obsolete to active.

Q: What are the key differences between Molex and TE Connectivity options?

A: The Molex 0526100771 maintains exact specifications of the original part. The TE Connectivity 1734248-7 operates at a reduced temperature minimum (-20°C versus -40°C), supports 20 mating cycles instead of 30, and features gold contact finish instead of tin bismuth. Height above board differs by 0.24mm. Both meet 125V/1A ratings and UL94 V-0 flammability requirements.

Q: Are there PCB layout considerations when switching between these parts?

A: The height above board difference between Molex (5.74mm) and TE Connectivity (5.50mm) is 0.24mm. This minor variation is within standard PCB design tolerances and does not typically require layout modification. Verify clearance in your specific application if space constraints exist.

Q: Which substitute should be selected for new designs?

A: The Molex 0526100771 is the manufacturer-recommended substitute and maintains full compatibility with the original specification. Select the TE Connectivity 1734248-7 only if Molex supply is unavailable and your application operates within the -20°C to 85°C temperature range and does not exceed 20 mating cycles.

Q: Are all substitutes RoHS compliant?

A: Yes. The Molex 0526100771 is ROHS3 compliant. The TE Connectivity 1734248-7 is RoHS compliant. Both meet environmental regulatory requirements for current manufacturing standards.
