Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HR25-9R-16SC(71) is determined by the following critical parameters that must remain constant:

• Connector Type & Function: Receptacle housing for female sockets
• Position Count: 16 positions
• Shell Size: Insert size 9
• Mounting Configuration: Panel mount with bulkhead rear side nut
• Fastening Mechanism: Push-pull
• Contact Type: Crimp
• Shell Material & Finish: Zinc alloy with nickel finish
• Operating Temperature Range: -25°C to 85°C
• Flammability Rating: UL94 V-0
• Regulatory Compliance: REACH Unaffected, ECCN EAR99

The HR25A-9R-16SC represents an active equivalent within the Hirose HR25 series family. While this substitute maintains all critical mechanical and electrical parameters, it introduces a design variation in shielding configuration and insert material composition that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The HR25A-9R-16SC is the active equivalent for the obsolete HR25-9R-16SC(71). Selection between these parts must account for the following engineering considerations:

Shielding Configuration: The original HR25-9R-16SC(71) incorporates shielding, while the HR25A-9R-16SC is unshielded. Applications requiring electromagnetic interference (EMI) mitigation must evaluate whether the unshielded configuration meets system-level shielding requirements through alternative means.

Insert Material: The HR25A-9R-16SC specifies Polyphenylene Sulfide (PPS) insert material, providing enhanced chemical resistance and thermal stability compared to the unspecified insert material of the original part.

Regulatory Compliance: The HR25A-9R-16SC carries active RoHS compliance certification, whereas the original part's RoHS status is not specified. For applications subject to RoHS directives, the HR25A-9R-16SC provides documented compliance assurance.

Product Status: The HR25A-9R-16SC maintains active production status with documented inventory availability (812 pcs), ensuring long-term supply chain continuity compared to the obsolete original part.

Frequently Asked Questions (FAQ)

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

A: The HR25A-9R-16SC maintains identical mechanical and electrical parameters for connector type, position count, shell size, mounting configuration, and fastening mechanism. However, the unshielded design of the HR25A-9R-16SC differs from the shielded original. Direct replacement is feasible only when EMI shielding is not a critical system requirement or when shielding is provided through alternative system-level measures.

Q: What is the significance of the keyed orientation feature in the HR25A-9R-16SC?

A: The HR25A-9R-16SC incorporates keyed orientation, which provides polarization to prevent incorrect mating. This design feature enhances assembly reliability and reduces installation errors compared to non-keyed configurations.

Q: Are the contact interfaces compatible between these two connector housings?

A: Both parts utilize crimp contact type with identical shell size 9 specifications. Contact compatibility is determined by the mating plug connector series and contact gauge specifications, which must be verified against the complete system connector architecture.

Q: What packaging considerations apply to the HR25A-9R-16SC?

A: The HR25A-9R-16SC is supplied in bulk packaging, whereas the original part's packaging specification is not provided. Bulk packaging may require internal inventory management procedures for component handling and traceability.

Q: Does the PPS insert material of the HR25A-9R-16SC affect operating temperature performance?

A: Both parts maintain identical operating temperature range specifications of -25°C to 85°C. The PPS insert material provides enhanced thermal stability and chemical resistance within this specified range.
