Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0872643050 is determined by strict alignment of the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 30 positions
• Pitch & Row Configuration: 0.079" (2.00mm) mating pitch with 2-row layout
• Mounting & Termination: Through-hole right-angle mounting with solder termination
• Electrical Ratings: 1A current rating and 125VAC voltage rating
• Contact Finish - Mating: Gold plating on mating surfaces
• Operating Temperature Range: -55°C to 105°C
• Fastening Type: Push-pull mechanism

The substitute part Molex 0872643052 maintains identical specifications across all critical parameters, with the primary distinction being product status (active vs. obsolete) and packaging format (tube vs. unspecified).

Parameter Comparison

Engineering Selection Recommendations

The Molex 0872643052 is a direct functional equivalent to the 0872643050 across all critical electrical and mechanical parameters. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The primary differences between the two parts are:

• Product Status: The 0872643052 is active, whereas the 0872643050 is obsolete. This distinction is significant for procurement and lifecycle management.
• RoHS Compliance: The 0872643052 achieves ROHS3 compliance, while the 0872643050 is non-compliant. This compliance difference may be relevant for applications subject to regulatory requirements.
• Contact Finish - Post: The 0872643050 features tin-lead post finish, while the 0872643052 uses tin post finish. Both finishes are compatible with standard solder processes.
• Packaging: The 0872643052 is supplied in tube packaging, whereas the 0872643050 packaging format is not specified.

For new designs and ongoing production requiring this connector type, the 0872643052 is the appropriate selection due to its active status and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Are the 0872643050 and 0872643052 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 30-position configuration, 0.079" (2.00mm) pitch, 2-row layout, right-angle through-hole mounting, and push-pull fastening. PCB footprints and mating interfaces are identical.

Q: What is the significance of the tin-lead versus tin post finish difference?

A: Both finishes are compatible with standard solder reflow and wave soldering processes. The tin-lead finish on the 0872643050 reflects older manufacturing standards, while the tin finish on the 0872643052 aligns with current lead-free soldering practices. This difference does not affect electrical or mechanical compatibility.

Q: Why is the 0872643050 classified as obsolete?

A: Obsolescence typically reflects end-of-life status in the manufacturer's product portfolio. The 0872643052 serves as the active production equivalent, ensuring continued availability of this connector type.

Q: Does RoHS3 compliance on the 0872643052 affect compatibility with existing designs?

A: No. RoHS3 compliance indicates adherence to regulatory restrictions on hazardous substances. This certification does not alter the electrical or mechanical performance of the connector and does not impact compatibility with existing applications.

Q: Can the 0872643052 be used as a direct replacement in existing assemblies?

A: Yes. The 0872643052 is a direct replacement for the 0872643050 in all applications. Identical electrical ratings (1A, 125VAC), operating temperature range (-55°C to 105°C), and mechanical specifications ensure seamless substitution.

Q: What is the difference in packaging between these parts?

A: The 0872643050 packaging format is not specified in available documentation. The 0872643052 is supplied in tube packaging. Packaging format does not affect connector performance or compatibility; it is relevant only for handling, storage, and procurement logistics.
