Key Parameters

Substitute Part Grouping Explanation

Substitution of the HR25-9R-16PC(71) is determined by the following critical parameters that must remain consistent:

• Connector Type & Function: Receptacle housing for male pins
• Position Count: 16 positions
• Shell Size: Insert size 9
• Mounting Configuration: Panel mount with bulkhead rear side nut
• Fastening Mechanism: Push-pull
• Shell Material & Finish: Zinc alloy with nickel plating
• Operating Temperature Range: -25°C ~ 85°C
• Contact Type: Crimp
• Contact Shape: Circular

The HR25A-9R-16PC qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Variations in shielding configuration and insert material do not prevent functional substitution when the application requirements permit such differences.

Parameter Comparison

Engineering Selection Recommendations

The HR25A-9R-16PC is the designated substitute for the obsolete HR25-9R-16PC(71). Selection of this substitute is supported by the following factors:

• Product Status: The HR25A-9R-16PC maintains active production status, ensuring continued availability and supply chain reliability.
• Compliance: Both parts maintain identical UL94 V-0 flammability ratings and EAR99 export classification.
• Functional Equivalence: All critical mechanical and electrical parameters align, including 16-position configuration, shell size 9, panel mount bulkhead design, and push-pull fastening.
• Environmental Specifications: Operating temperature range and moisture sensitivity levels are identical.
• Material Specifications: Zinc alloy shell with nickel finish and circular contact geometry remain consistent.

The primary difference is the shielding configuration (shielded vs. unshielded) and insert material composition. Selection between these variants depends on application-specific electromagnetic interference requirements and mechanical stress considerations.

Frequently Asked Questions (FAQ)

Q: Can the HR25A-9R-16PC directly replace the HR25-9R-16PC(71) in existing assemblies?

A: Yes, the HR25A-9R-16PC is mechanically and electrically compatible. Both parts share identical shell size, position count, mounting configuration, and fastening mechanism. Physical installation and mating with corresponding plug connectors will function identically.

Q: What is the significance of the shielding difference between these parts?

A: The HR25-9R-16PC(71) features shielded construction, while the HR25A-9R-16PC is unshielded. Shielding provides electromagnetic interference (EMI) suppression. Applications requiring EMI protection should evaluate whether the unshielded substitute meets performance requirements.

Q: Are there differences in insert material that affect compatibility?

A: The HR25-9R-16PC(71) does not specify insert material in the provided data. The HR25A-9R-16PC uses Polyphenylene Sulfide (PPS) insert material. This material provides mechanical stability and thermal resistance consistent with the operating temperature range of both parts.

Q: What is the difference between HR25 and HR25A series designations?

A: The HR25A represents an updated series within the Hirose Electric circular connector product line. The HR25A-9R-16PC maintains functional compatibility with the earlier HR25-9R-16PC(71) while offering active production status and updated material specifications.

Q: Are both parts RoHS compliant?

A: The HR25A-9R-16PC is explicitly RoHS compliant. RoHS status for the HR25-9R-16PC(71) is not specified in the provided data. Verify RoHS compliance requirements for your specific application before final selection.

Q: What packaging options are available?

A: The HR25-9R-16PC(71) packaging is not specified. The HR25A-9R-16PC is supplied in bulk packaging. Confirm packaging requirements with your procurement process.
