Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MXR-8RA-4S is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle with female sockets
• Number of positions: 4
• Shell size - insert: 8
• Mounting configuration: Panel mount with bulkhead rear side nut
• Termination method: Solder cup
• Fastening mechanism: Push-pull with keyed orientation
• Series compatibility: MXR series

The substitute part MXR-8RA-4S(71) maintains full equivalence across all mechanical and electrical interface parameters. The primary distinction is the addition of specified material compositions, contact finishes, and electrical ratings in the substitute variant, along with improved RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The MXR-8RA-4S(71) serves as the direct substitute for the obsolete MXR-8RA-4S. Selection of the substitute part is supported by the following factors:

• Full mechanical and electrical interface compatibility across all specified parameters
• RoHS compliance status of MXR-8RA-4S(71) aligns with current regulatory requirements, whereas the original part is RoHS non-compliant
• Product status of MXR-8RA-4S(71) as Last Time Buy indicates continued availability from the manufacturer, contrasting with the obsolete status of the original part
• Specified electrical ratings (2A current, 100VAC/140VDC voltage) and operating temperature range (-25°C ~ 85°C) are documented for the substitute variant
• Material specifications and contact finishes are fully defined for MXR-8RA-4S(71), providing complete technical documentation for design validation

Frequently Asked Questions (FAQ)

Q: Can MXR-8RA-4S(71) be used as a direct replacement for MXR-8RA-4S?

A: Yes. Both parts maintain identical mechanical interfaces, connector configuration, and mounting specifications. The substitute part provides additional material and electrical specifications not documented for the original part.

Q: What is the primary difference between these two part numbers?

A: The MXR-8RA-4S(71) includes specified material compositions (aluminum alloy shell, phosphor bronze contacts with gold plating), electrical ratings (2A, 100VAC/140VDC), and RoHS compliance. The original MXR-8RA-4S lacks these detailed specifications.

Q: Is the MXR-8RA-4S(71) RoHS compliant?

A: Yes. MXR-8RA-4S(71) is RoHS compliant, whereas the original MXR-8RA-4S is RoHS non-compliant.

Q: What is the operating temperature range for the substitute part?

A: The MXR-8RA-4S(71) operates within -25°C to 85°C.

Q: Are there packaging differences between these parts?

A: The original MXR-8RA-4S packaging is not specified. The MXR-8RA-4S(71) is supplied in bulk packaging.

Q: What is the current rating for the MXR-8RA-4S(71)?

A: The substitute part is rated for 2A continuous current.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes, provided the design does not depend on specifications not documented for the original MXR-8RA-4S. The substitute part's documented electrical and material specifications ensure compatibility with standard circular connector interface requirements.
