Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MXR-8R-8SA(71) is determined by the following critical parameters:

• 8-position connector configuration
• Female socket connector type
• Solder termination method
• Gold-plated mating contacts
• 2A current rating capability
• Panel mount through-hole installation
• Operating temperature range compatibility (-25°C minimum, 85°C maximum)
• RoHS compliance status

The substitute parts identified (1441930 and 43-01665) satisfy these core electrical and mechanical requirements. However, differences exist in shell size designation, fastening mechanism, ingress protection rating, and voltage rating specifications that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain active product status, ensuring continued availability and manufacturer support. The 1441930 (Phoenix Contact DSI series) and 43-01665 (Amphenol CONEC 43 series) are ROHS3 compliant, meeting current regulatory requirements.

Key considerations for selection:

The 1441930 maintains receptacle configuration matching the original MXR-8R-8SA(71), with identical fastening orientation (keyed/A orientation). This part provides IP67 ingress protection, exceeding the original specification.

The 43-01665 differs in connector type (plug versus receptacle) and fastening mechanism (threaded versus push-pull). This configuration change requires mechanical interface redesign and is suitable only when plug-type connectors are functionally acceptable.

Voltage rating reduction from 100VAC/140VDC to 30V in both substitutes requires verification against application requirements. Current rating (2A) and operating temperature range remain compatible with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 1441930 directly replace the MXR-8R-8SA(71) without PCB modification?

A: The 1441930 maintains panel mount through-hole installation and receptacle configuration. Fastening mechanism differs (Push-Twist versus Push-Pull), requiring evaluation of mechanical compatibility with mating connectors and panel mounting hardware.

Q: Why is the 43-01665 listed as a substitute if it is a plug connector?

A: The 43-01665 satisfies core electrical parameters (8-position, 2A, gold-plated contacts, solder termination). However, plug versus receptacle configuration represents a functional difference requiring circuit design assessment.

Q: What is the impact of the 30V voltage rating in substitute parts?

A: The original MXR-8R-8SA(71) supports 100VAC and 140VDC. Substitute parts are rated 30V maximum. Applications exceeding 30V require alternative solutions or voltage derating analysis.

Q: Are the substitute parts compatible with existing mating connectors?

A: Mechanical compatibility depends on shell size, fastening type, and orientation specifications. The 1441930 uses M12-8 shell size with A orientation; the original uses 8 shell size designation. Physical interface verification is required.

Q: Do substitute parts maintain RoHS compliance?

A: Both substitute parts are ROHS3 compliant, meeting current regulatory standards. The original MXR-8R-8SA(71) is RoHS compliant, satisfying legacy requirements.
