Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HR25-9P-16SC(72) is determined by the following critical parameters that must remain consistent:

• Connector Type & Position Count: Plug housing with 16 positions
• Shell Size: Insert size 9 (mechanical compatibility with mating female sockets)
• Mounting Configuration: Free hanging (in-line) orientation
• Fastening Mechanism: Push-pull engagement system
• Material & Finish: Zinc alloy with nickel plating for corrosion resistance
• Operating Temperature Range: -25°C ~ 85°C
• Flammability Compliance: UL94 V-0 rating
• Contact Interface: Crimp-type contacts for female socket mating

The HR25A-9P-16SC qualifies as a direct substitute based on matching all critical mechanical and electrical parameters. Differences in shielding configuration, insert material, and product status do not prevent functional substitution when application requirements are evaluated.

Parameter Comparison

Engineering Selection Recommendations

The HR25A-9P-16SC is the active production equivalent for the obsolete HR25-9P-16SC(72). Selection between these parts is based on the following engineering criteria:

Product Status & Availability: The HR25-9P-16SC(72) is obsolete with limited remaining inventory (899 pcs). The HR25A-9P-16SC is active production status with current availability (857 pcs), ensuring long-term supply chain continuity and support.

Compliance & Regulatory: Both parts meet UL94 V-0 flammability requirements and share identical ECCN and HTSUS classifications. The HR25A-9P-16SC carries ROHS3 compliance, meeting current environmental regulations. REACH status differs (Unaffected vs. Affected), requiring evaluation based on application geography and regulatory requirements.

Mechanical & Electrical Compatibility: Both connectors maintain identical shell size (9), position count (16), mounting configuration (free hanging in-line), and fastening mechanism (push-pull). Contact type, material composition, and operating temperature range are equivalent, ensuring direct mechanical and electrical interchangeability.

Design Enhancements: The HR25A-9P-16SC includes integrated backshell, cable clamp, and strain relief features not present in the original part. These additions provide improved cable management and mechanical robustness without affecting connector interface compatibility.

Shielding Consideration: The HR25-9P-16SC(72) features shielded design while the HR25A-9P-16SC is unshielded. Applications requiring electromagnetic interference protection must evaluate whether the unshielded substitute meets EMC requirements. If shielding is mandatory, alternative shielded variants within the HR25A series should be investigated.

Frequently Asked Questions (FAQ)

Q: Can the HR25A-9P-16SC directly replace the HR25-9P-16SC(72) in existing assemblies?

A: Yes, for applications where shielding is not a critical requirement. Both connectors share identical shell size (9), position count (16), mounting type (free hanging in-line), and fastening mechanism (push-pull). The mechanical and electrical interfaces are fully compatible. However, if the original design relied on shielded connector properties for EMC performance, the unshielded HR25A-9P-16SC may not be suitable without additional shielding measures.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Product status—HR25-9P-16SC(72) is obsolete while HR25A-9P-16SC is active production; (2) Shielding—original is shielded, substitute is unshielded; (3) Features—HR25A-9P-16SC includes backshell, cable clamp, and strain relief; (4) Insert material—HR25A-9P-16SC specifies Polyphenylene Sulfide (PPS); (5) Orientation—HR25A-9P-16SC is keyed; (6) Compliance—HR25A-9P-16SC is ROHS3 compliant. All other parameters including operating temperature, flammability rating, and contact type remain identical.

Q: Are there packaging differences between these parts?

A: The HR25-9P-16SC(72) packaging is not specified in available data. The HR25A-9P-16SC is supplied in bulk packaging. Confirm packaging requirements with your procurement specification before ordering.

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

A: Keyed orientation provides polarization to prevent incorrect mating. If the original application used non-keyed connectors, the keyed design of the HR25A-9P-16SC will not mate with non-keyed female sockets. Verify that mating female socket connectors support keyed engagement before substitution.

Q: What is the impact of the unshielded design on my application?

A: Unshielded connectors do not provide electromagnetic interference (EMI) protection. If your application operates in an electromagnetically noisy environment or requires EMC compliance, evaluate whether unshielded operation meets performance requirements. If shielding is necessary, consult Hirose Electric documentation for shielded variants within the HR25A series.

Q: Are both parts compliant with current environmental regulations?

A: The HR25A-9P-16SC is ROHS3 compliant and REACH affected, meeting current EU environmental directives. The HR25-9P-16SC(72) is REACH unaffected. For applications subject to ROHS or REACH regulations, the HR25A-9P-16SC is the compliant choice. Verify regulatory requirements for your specific application geography.
