Key Parameters

Substitute Part Grouping Explanation

Substitution of the HR25-9P-20PC(72) is determined by the following critical parameters that must remain constant:

• Number of Positions: 20 positions (electrical interface requirement)
• Shell Size - Insert: 9 (mechanical fit requirement)
• Connector Type: Plug Housing for male pins (functional requirement)
• Fastening Type: Push-Pull (operational requirement)
• Mounting Type: Free Hanging (In-Line) (installation requirement)
• Contact Type: Crimp (termination method)
• Operating Temperature Range: -25°C ~ 85°C (environmental requirement)

The HR25A-9P-20PC qualifies as a direct substitute based on matching all critical parameters. Differences in secondary characteristics such as shielding configuration, backshell features, and compliance certifications do not prevent functional substitution when these variations are acceptable for the application.

Parameter Comparison

Engineering Selection Recommendations

The HR25A-9P-20PC is the designated substitute for the obsolete HR25-9P-20PC(72). Selection of this substitute is supported by the following factors:

Product Status: The HR25A-9P-20PC maintains active product status with Hirose Electric Co Ltd, ensuring continued availability and manufacturing support. The original HR25-9P-20PC(72) is obsolete, necessitating transition to the active substitute.

Compliance and Certifications: Both parts maintain identical material flammability ratings (UL94 V-0) and operating temperature specifications (-25°C ~ 85°C). The HR25A-9P-20PC achieves ROHS3 compliance, providing enhanced environmental regulatory alignment compared to the original part.

Functional Equivalence: All critical electrical and mechanical parameters remain constant between the two parts, including 20-position configuration, shell size 9, push-pull fastening, and crimp contact type.

Secondary Differences: The HR25A-9P-20PC includes integrated backshell, cable clamp, and strain relief features not present in the original part. The substitute features unshielded construction compared to the shielded original. These differences must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the HR25A-9P-20PC directly replace the HR25-9P-20PC(72) in existing assemblies?

A: The HR25A-9P-20PC matches all critical substitution parameters: 20 positions, shell size 9, push-pull fastening, free hanging mounting, and crimp contacts. Physical and electrical compatibility is established. Shielding differences and integrated strain relief features must be evaluated for your specific application.

Q: What is the difference between shielded and unshielded configurations?

A: The original HR25-9P-20PC(72) provides shielded construction. The substitute HR25A-9P-20PC is unshielded. Shielding affects electromagnetic interference (EMI) performance. Applications requiring EMI protection must assess whether unshielded operation is acceptable.

Q: Are the backshell, cable clamp, and strain relief features on the HR25A-9P-20PC compatible with existing cable assemblies?

A: The HR25A-9P-20PC includes integrated backshell, cable clamp, and strain relief. These features may affect cable assembly design and installation procedures. Verify compatibility with existing cable termination and assembly methods.

Q: What is the inventory status of these parts?

A: The HR25-9P-20PC(72) has 1060 pieces in stock as new original inventory. The HR25A-9P-20PC has 900 pieces in stock as new original inventory in bulk packaging.

Q: Are both parts subject to the same regulatory requirements?

A: Both parts maintain UL94 V-0 flammability ratings and unlimited moisture sensitivity levels (MSL 1). The HR25A-9P-20PC is ROHS3 compliant. Both are classified under ECCN EAR99 and HTSUS 8538.90.8180.

Q: What is the base product number for each part?

A: The HR25-9P-20PC(72) belongs to the HR25 base series. The HR25A-9P-20PC belongs to the HR25A base series. Both series are manufactured by Hirose Electric Co Ltd.
