Molex 0524782815 Equivalent & Substitute Parts

Part Overview

The Molex 0524782815 is a 28-position rectangular receptacle connector with IDC (Insulation Displacement Contact) termination, designed for discrete wire applications in the 26-28 AWG range. This connector features a tin contact finish and operates in a free-hanging, in-line configuration with a 2.00mm pitch across two rows.

The 0524782815 is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations. Substitute connectors must maintain electrical and mechanical compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0524782815 is determined by the following critical parameters:

• Connector Type & Position Count: Must be a 28-position receptacle connector
• Pitch & Row Configuration: Must maintain 2.00mm pitch with 2-row layout
• Cable Termination Method: Must support IDC termination
• Mounting Configuration: Must be free-hanging, in-line style
• Contact Type: Must be female socket contacts
• Wire Gauge Compatibility: Must accommodate 28 AWG minimum (26-28 AWG range acceptable)

The Amphenol ICC (FCI) 89947-728LF meets all substitution criteria. While it specifies 28 AWG discrete wire capacity (versus the original 26-28 AWG range), it maintains full mechanical and electrical compatibility through IDC termination and identical pitch/position configuration.

Engineering Selection Recommendations

Primary Substitute: Amphenol ICC (FCI) 89947-728LF

The 89947-728LF is the designated manufacturer-recommended substitute for the obsolete Molex 0524782815. Selection of this substitute is supported by:

• Active Product Status: The 89947-728LF maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Compliance Alignment: Both connectors meet RoHS and MSL requirements; the substitute carries current RoHS certification
• Mechanical Compatibility: Identical pitch, row configuration, and mounting style ensure direct physical compatibility
• Electrical Compatibility: IDC termination method and 28 AWG wire gauge support maintain signal integrity for discrete wire applications
• Contact Finish Difference: The substitute features gold plating versus tin on the original. Gold contact finish provides enhanced corrosion resistance and is suitable for applications requiring extended service life or exposure to environmental stress

The contact finish upgrade from tin to gold represents an improvement in reliability characteristics and does not compromise compatibility with existing mating connectors or cable assemblies.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 89947-728LF directly replace the Molex 0524782815 in existing assemblies?

A: Yes. Both connectors share identical pitch (2.00mm), position count (28), row configuration (2), and mounting style (free-hanging, in-line). IDC termination compatibility ensures direct substitution in cable assemblies and PCB applications.

Q: What is the significance of the contact finish difference (tin vs. gold)?

A: Contact finish affects corrosion resistance and long-term reliability. Gold plating on the 89947-728LF provides superior protection in humid or corrosive environments compared to tin. This represents a material upgrade and does not affect electrical or mechanical compatibility.

Q: Does the wire gauge specification difference (26-28 AWG vs. 28 AWG) affect substitution?

A: No. The substitute's 28 AWG specification falls within the original 26-28 AWG range. IDC termination accommodates this wire gauge without performance degradation. Applications using 26 AWG wire should confirm compatibility with the substitute's IDC contact design.

Q: Are there packaging or inventory considerations for the substitute?

A: The 89947-728LF is supplied in tube packaging with 898 pieces in current stock, compared to the original's bulk inventory status. Verify packaging requirements for your procurement and assembly processes.

Q: What compliance certifications apply to both connectors?

A: Both connectors are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. The substitute maintains REACH compliance and EAR99 export classification, matching the original's regulatory profile.
