Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HR25-9R-20SC(71) is determined by strict alignment of the following critical parameters:

• Connector Type & Position Count: Receptacle housing with 20 positions
• Shell Size: Insert size 9
• Mounting Configuration: Panel mount with bulkhead rear side nut
• Fastening Mechanism: Push-pull fastening
• Shell Material & Finish: Zinc alloy with nickel finish
• Contact Specifications: Crimp contact type with circular contact shape
• Operating Temperature Range: -25°C ~ 85°C
• Flammability Compliance: UL94 V-0
• Regulatory Status: REACH Unaffected, ECCN EAR99

The HR25A-9R-20SC qualifies as a direct substitute based on matching all critical parameters. Variations in shielding configuration and insert material do not preclude substitution when electromagnetic shielding requirements are not mandated by the application specification.

Parameter Comparison

Engineering Selection Recommendations

The HR25A-9R-20SC is the active equivalent for the obsolete HR25-9R-20SC(71). Selection of this substitute is supported by:

• Product Status Alignment: The substitute maintains active manufacturing status, ensuring long-term availability and supply chain reliability.
• Compliance Enhancement: The HR25A-9R-20SC carries RoHS Compliance certification, providing regulatory advantage for applications subject to RoHS directives.
• Functional Equivalence: All critical electrical and mechanical parameters match the original specification, including connector type, position count, shell size, mounting configuration, fastening mechanism, material composition, and operating temperature range.
• Shielding Consideration: The substitute features unshielded construction versus the shielded original. Applications requiring electromagnetic shielding must evaluate this difference against specific EMI/RFI requirements.

Frequently Asked Questions (FAQ)

Q: Can HR25A-9R-20SC directly replace HR25-9R-20SC(71) in existing designs?

A: Yes, provided the application does not mandate electromagnetic shielding. The substitute matches all critical parameters including connector type, position count, shell size, mounting configuration, fastening mechanism, material composition, and operating temperature range.

Q: What is the primary difference between these two parts?

A: The HR25-9R-20SC(71) features shielded construction, while the HR25A-9R-20SC is unshielded. Additionally, the substitute is RoHS Compliant and maintains active product status.

Q: Does the insert material difference affect compatibility?

A: The HR25A-9R-20SC specifies Polyphenylene Sulfide (PPS) insert material. This does not affect mechanical or electrical compatibility with standard crimp contacts designed for 20-position size 9 circular connectors.

Q: Is the HR25A-9R-20SC available in the same packaging as the original?

A: The substitute is supplied in bulk packaging, whereas the original packaging specification was not provided. Verify packaging requirements with your procurement specification.

Q: What is the inventory status for the substitute part?

A: The HR25A-9R-20SC has 1030 pieces in new original stock, providing adequate supply for component selection.
