Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MXR-8PA-3PB is determined by strict alignment of the following critical parameters:

• Connector type and gender (Plug, Male Pins)
• Number of positions (3)
• Shell size designation (8)
• Termination method (Solder Cup)
• Fastening mechanism (Push-Pull)
• Orientation feature (Keyed)
• Mounting configuration (Free Hanging, In-Line)
• Shell material composition (Aluminum Alloy)
• Shell finish specification (Nickel)

The substitute part MXR-8PA-3PB(71) maintains full compatibility across all these core parameters, ensuring mechanical and electrical interchangeability within the MXR series platform.

Parameter Comparison

Engineering Selection Recommendations

The MXR-8PA-3PB(71) serves as the direct substitute for the obsolete MXR-8PA-3PB. Key selection considerations include:

Product Status: The main part is classified as obsolete, while the substitute is designated Last Time Buy. This status transition indicates limited future availability of the original component, making the substitute the appropriate choice for new designs and ongoing production requirements.

Compliance Profile: The substitute part achieves RoHS compliance, whereas the original part is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the MXR-8PA-3PB(71) is the required selection.

Electrical Specifications: The substitute provides defined electrical ratings (2A current, 100VAC/140VDC voltage) and operating temperature range (-25°C to 85°C), whereas the original part does not specify these parameters. Applications requiring documented electrical performance should utilize the substitute.

Contact Finish Enhancement: The substitute features gold-plated mating contacts compared to the unspecified finish of the original part, providing improved corrosion resistance and contact reliability.

Mechanical Compatibility: Both parts maintain identical mechanical interfaces, shell dimensions, and fastening characteristics, ensuring direct physical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can MXR-8PA-3PB(71) be used as a direct replacement for MXR-8PA-3PB?

A: Yes. Both connectors share identical mechanical specifications including connector type, pin count, shell size, termination method, fastening type, and orientation. The substitute maintains full compatibility with existing mating connectors and PCB layouts designed for the original part.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete versus Last Time Buy), RoHS compliance status, contact finish specification (gold plating on the substitute), and documented electrical ratings. The substitute provides enhanced specifications and regulatory compliance.

Q: Are there any compatibility concerns when substituting MXR-8PA-3PB(71) for MXR-8PA-3PB?

A: No compatibility concerns exist for mechanical or electrical interfaces. Both parts are from the same MXR series and maintain identical connector geometry, pin configuration, and fastening mechanisms.

Q: What is the packaging difference between these parts?

A: The original part packaging is not specified, while the substitute is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Why should I select the substitute if the original part is still in stock?

A: The original part is classified as obsolete with no future production planned. The substitute is designated Last Time Buy, indicating limited remaining availability. For long-term supply chain security and regulatory compliance, the substitute is the recommended selection.

Q: Does the gold contact finish on the substitute affect compatibility?

A: No. The gold plating on mating contacts is a performance enhancement that improves corrosion resistance and contact reliability. It does not affect mechanical or electrical compatibility with existing mating connectors.
