Key Parameters

Substitute Part Grouping Explanation

Substitution of the HR25-9P-16PC(72) is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Plug housing for male pins with 16 positions
• Shell Size: Insert size 9 maintains mechanical compatibility with mating receptacles
• Mounting & Fastening: Free hanging (in-line) configuration with push-pull fastening mechanism
• Contact Interface: Crimp contact type for consistent termination methodology
• Material & Environmental Compliance: Zinc alloy shell with nickel finish, UL94 V-0 flammability rating, and operating temperature range of -25°C ~ 85°C
• Regulatory Status: REACH Unaffected classification

The HR25A-9P-16PC qualifies as a direct substitute based on these parameters. However, the following differences must be noted for engineering evaluation:

• Product Status: HR25A-9P-16PC is Active (vs. Obsolete for HR25-9P-16PC(72))
• Shielding: HR25A-9P-16PC is Unshielded (vs. Shielded for HR25-9P-16PC(72))
• Additional Features: HR25A-9P-16PC includes backshell, cable clamp, and strain relief
• Keying: HR25A-9P-16PC features keyed orientation
• Insert Material: HR25A-9P-16PC specifies Polyphenylene Sulfide (PPS)
• RoHS Status: HR25A-9P-16PC is RoHS Compliant

Parameter Comparison

Engineering Selection Recommendations

The HR25A-9P-16PC is the active equivalent for the obsolete HR25-9P-16PC(72). Selection between these parts must account for the following engineering considerations based on provided specifications:

Shielding Difference: The original HR25-9P-16PC(72) is shielded, while the HR25A-9P-16PC is unshielded. Applications requiring electromagnetic interference (EMI) mitigation must evaluate whether the unshielded configuration meets system requirements.

Enhanced Features: The HR25A-9P-16PC includes integrated backshell, cable clamp, and strain relief, providing improved cable management and mechanical robustness compared to the base HR25-9P-16PC(72) configuration.

Keying: The HR25A-9P-16PC incorporates keyed orientation, preventing incorrect mating and enhancing assembly reliability.

Regulatory Compliance: The HR25A-9P-16PC carries RoHS Compliance certification, meeting current environmental regulations. Both parts maintain UL94 V-0 flammability rating and identical operating temperature specifications.

Product Status: The HR25A-9P-16PC is in active production, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can HR25A-9P-16PC directly replace HR25-9P-16PC(72) in existing designs?

A: Mechanical and electrical compatibility is established through matching connector type, position count, shell size, fastening mechanism, and contact interface. However, the shielding difference must be evaluated for your specific application. The HR25A-9P-16PC's additional features (backshell, cable clamp, strain relief) and keying provide enhanced functionality.

Q: What is the significance of the shielding difference?

A: The HR25-9P-16PC(72) provides shielded construction for EMI protection. The HR25A-9P-16PC is unshielded. Applications in electromagnetically noisy environments may require shielded alternatives or external shielding provisions.

Q: Does the keyed orientation of HR25A-9P-16PC affect compatibility?

A: Keying prevents incorrect mating orientation, enhancing assembly safety and reliability. This is a functional improvement that does not compromise backward compatibility with existing mating receptacles designed for the HR25 series.

Q: Are the operating temperature ranges identical?

A: Both parts operate across -25°C ~ 85°C, maintaining thermal performance equivalence.

Q: What is the impact of RoHS Compliance on HR25A-9P-16PC?

A: RoHS Compliance indicates the part meets current environmental regulations restricting hazardous substances. This supports compliance with modern procurement and manufacturing standards.

Q: Are contacts included with either part?

A: Neither the HR25-9P-16PC(72) nor the HR25A-9P-16PC includes contacts. Contacts must be sourced separately and crimped according to Hirose specifications.
