Molex 0526100975 FPC Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0526100975 is a 9-position FPC (Flat Flexible) connector from the Easy-On 52610 series, designed for surface mount applications with 1.00mm pitch spacing. This connector features vertical orientation, zero insertion force (ZIF) operation, and slide lock retention. The part is currently active in production with 669 units in stock.

Substitute parts become necessary when the primary part number reaches end-of-life status, when packaging requirements differ (Tape & Reel versus Cut Tape), or when specific contact finish specifications are required for application compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0526100975 is determined by the following critical parameters:

Connector geometry: 9 positions, 1.00mm pitch, vertical orientation, 1-sided contacts
Mounting interface: Surface mount with 0.226" (5.74mm) height above board
Mechanical retention: Slide lock mechanism
Electrical termination: Solder attachment
Material compatibility: FFC thickness of 0.30mm, polyamide housing, phosphor bronze contacts

The substitute parts 0526100933 and 0526100972 maintain identical mechanical and electrical interfaces across these parameters. Differences exist only in packaging format (Cut Tape versus Tape & Reel), contact finish composition (Tin Bismuth versus Gold), and product status classification.

Engineering Selection Recommendations

0526100975 (Primary Selection) Use this part number when Tape & Reel packaging is required for automated assembly processes and when Tin Bismuth contact finish meets application requirements. This part maintains active production status with established supply continuity.

0526100972 (Preferred Substitute) This part number is the recommended substitute when the primary part becomes unavailable. It maintains identical mechanical and electrical interfaces, active product status, and Tape & Reel packaging. The Gold contact finish provides enhanced corrosion resistance compared to Tin Bismuth, making it suitable for extended storage or high-humidity environments. Significantly higher inventory availability (30090 units) ensures supply security.

0526100933 (Secondary Substitute) This part number is suitable only when Cut Tape packaging is acceptable for manual or semi-automated assembly processes. The part carries obsolete status classification, indicating no new production. Glass-filled actuator material provides enhanced mechanical strength. Use only when packaging format is the determining factor and supply from active alternatives is unavailable.

Frequently Asked Questions (FAQ)

Q: Are these parts mechanically interchangeable? A: Yes. All three part numbers share identical connector geometry, pitch spacing (1.00mm), mounting height (0.226"), and locking mechanism. They are directly interchangeable at the PCB interface level.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly equipment. Cut Tape packaging is supplied as individual segments, suitable for manual or semi-automated assembly. Both formats contain the same connector component.

Q: Does contact finish affect electrical performance? A: Contact finish affects corrosion resistance and long-term reliability in specific environments. Tin Bismuth finish (0526100975, 0526100933) and Gold finish (0526100972) both meet the electrical requirements for this connector class. Gold finish provides superior corrosion resistance in high-humidity or salt-spray environments.

Q: Why is 0526100933 marked as obsolete? A: Obsolete status indicates the manufacturer has discontinued new production. Existing inventory may remain available, but no replenishment is guaranteed. For new designs, select from active part numbers 0526100975 or 0526100972.

Q: Can I use 0526100972 as a direct replacement for 0526100975? A: Yes. Both parts are active, use identical Tape & Reel packaging, and maintain the same mechanical and electrical specifications. The Gold contact finish of 0526100972 is compatible with all applications designed for the Tin Bismuth finish of 0526100975.

Q: What does the Easy-On 52610 series designation mean? A: This is the Molex product series classification. All three substitute parts belong to the same series, confirming their design compatibility and interchangeability within the connector family.
