Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MXR-8R-3SA(71) is determined by the following critical parameters:

• Connector Type & Position Count: Must be Receptacle, Female Sockets with 3 positions
• Shell Size: Must match Shell Size - Insert 8
• Fastening & Orientation: Must maintain Push-Pull fastening with keyed orientation
• Electrical Ratings: Current rating 2A and voltage rating 100VAC, 140VDC must be maintained
• Material & Compliance: Shell material (Aluminum Alloy), contact finish (Gold), and RoHS compliance must be preserved
• Operating Temperature Range: Must support -25°C ~ 85°C

The substitute part MXR-8RA-3S(71) meets all critical substitution criteria. The primary difference is the termination method: the main part uses solder termination with through-hole mounting, while the substitute uses solder cup termination with bulkhead rear-side nut mounting. Both maintain identical electrical performance, material specifications, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MXR-8RA-3S(71) is a qualified substitute for the MXR-8R-3SA(71) based on electrical equivalence and compliance alignment. Both parts are manufactured by Hirose Electric Co Ltd, carry RoHS compliance certification, and maintain identical electrical ratings and operating specifications.

Selection between these parts depends on installation requirements:

• MXR-8R-3SA(71): Select when through-hole solder termination with flange mounting is required for direct PCB integration.
• MXR-8RA-3S(71): Select when solder cup termination with bulkhead rear-side nut mounting is required for cable assembly or panel-mounted applications.

Both parts share Last Time Buy status, requiring procurement planning for long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can MXR-8RA-3S(71) be used as a direct replacement for MXR-8R-3SA(71)?

A: Electrical and mechanical compatibility is confirmed. However, mounting and termination methods differ. MXR-8R-3SA(71) uses through-hole solder termination with flange mounting, while MXR-8RA-3S(71) uses solder cup termination with bulkhead rear-side nut mounting. Design integration must account for these installation differences.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both parts maintain 2A current rating, 100VAC/140VDC voltage rating, and -25°C to 85°C operating temperature range.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS compliant, carry UL94 V-0 flammability rating, and have Moisture Sensitivity Level 1 (Unlimited).

Q: What is the primary functional difference between these connectors?

A: The primary difference is termination method. MXR-8R-3SA(71) is designed for PCB through-hole solder termination, while MXR-8RA-3S(71) is designed for cable solder cup termination with panel bulkhead mounting.

Q: Are both parts available in the same packaging?

A: Yes. Both parts are supplied in Bulk packaging.
