Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0527601409 is determined by strict alignment of the following critical parameters:

• Connector Type: Receptacle with center strip contacts
• Position Count: 140 positions
• Pitch: 0.025" (0.64mm)
• Row Configuration: 2 rows
• Mounting Technology: Surface mount
• Contact Material & Finish: Gold plating at 10.0µin thickness
• Regulatory Compliance: ROHS3 and REACH status

The substitute part Molex 0528851474 satisfies all these criteria while offering active product status and improved availability. Differences in mated stacking heights and height above board are within acceptable mechanical tolerances for connector receptacles and do not preclude functional substitution.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0528851474 is the qualified substitute for the obsolete 0527601409. Both components maintain identical electrical specifications, contact configuration, and regulatory compliance certifications. The substitute part carries active product status with higher inventory availability (1226 units versus 786 units), ensuring supply chain continuity.

The mechanical differences—height above board variance of 0.008" (0.20mm) and the absence of the 5mm stacking height option in the substitute—are minor and do not affect connector functionality or mating compatibility. These variations fall within standard mechanical tolerances for rectangular connector receptacles and do not introduce electrical performance degradation.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current and future applications.

Frequently Asked Questions (FAQ)

Q: Can the 0528851474 directly replace the 0527601409 in existing designs?

A: Yes. Both parts share identical electrical specifications, contact pitch, position count, and gold plating thickness. The substitute maintains full functional compatibility with mating connectors designed for the original part.

Q: What is the significance of the height above board difference?

A: The 0.008" (0.20mm) difference in height above board is a minor mechanical variation typical among connector series iterations. This does not affect electrical performance or mating compatibility with standard connector plugs.

Q: Why is the 5mm stacking height unavailable in the substitute?

A: The 0528851474 supports stacking heights from 6mm to 10mm, covering the majority of standard applications. If the 5mm stacking height is critical to your design, the original part specifications should be reviewed for alternative solutions.

Q: Are there packaging differences between these parts?

A: The original part has unspecified packaging, while the substitute is supplied in Cut Tape (CT) format. This is a standard packaging configuration for surface mount components and does not affect component performance.

Q: Do both parts meet current regulatory standards?

A: Yes. Both the 0527601409 and 0528851474 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
