Parameter Comparison

Engineering Selection Recommendations

The HR25A-9P-12PC is the appropriate selection for new designs and ongoing production requirements. This part maintains full mechanical and electrical compatibility with the obsolete HR25-9P-12PC(72) while offering active product status, ensuring sustained manufacturing support and supply availability.

The HR25A-9P-12PC provides RoHS compliance certification, which may be required for applications subject to environmental regulations. The addition of backshell, cable clamp, and strain relief features enhances mechanical durability in field installations without compromising form factor or mating interface compatibility.

For applications where shielding characteristics are critical, note that the HR25-9P-12PC(72) provides shielded construction, while the HR25A-9P-12PC is unshielded. Electrical performance requirements must be evaluated to determine if this difference impacts system functionality.

Frequently Asked Questions (FAQ)

Q: Can HR25A-9P-12PC directly replace HR25-9P-12PC(72) in existing assemblies?

A: Yes. Both parts share identical pin count (12 positions), shell size (9), mounting configuration (free hanging in-line), and fastening mechanism (push-pull). Mating interface compatibility is maintained. The HR25A-9P-12PC includes additional mechanical features (backshell, cable clamp, strain relief) that do not interfere with existing connector interfaces.

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

A: The HR25-9P-12PC(72) is shielded, while the HR25A-9P-12PC is unshielded. Shielding provides electromagnetic interference (EMI) protection. Applications requiring EMI mitigation must evaluate whether unshielded construction is acceptable for their electrical environment.

Q: Does the HR25A-9P-12PC include contacts?

A: No. Both the HR25-9P-12PC(72) and HR25A-9P-12PC are plug housings supplied without contacts. Contacts must be procured separately and crimped into the housing.

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

A: HR25A represents an enhanced variant of the HR25 series with improved mechanical features and active manufacturing status. The HR25A-9P-12PC maintains dimensional compatibility with HR25-9P-12PC(72) while offering modern design enhancements and regulatory compliance.

Q: Is the HR25A-9P-12PC RoHS compliant?

A: Yes. The HR25A-9P-12PC is RoHS compliant. The HR25-9P-12PC(72) RoHS status is not specified in available documentation.

Q: What packaging is available for the HR25A-9P-12PC?

A: The HR25A-9P-12PC is supplied in bulk packaging.
