Key Parameters

Substitute Part Grouping Explanation

The HR25A-9P-16P qualifies as a direct substitute for the HR25-9P-16P(72) based on the following critical parameters:

• Connector Configuration: Both are 16-position circular connector plugs with male pins
• Shell Size: Both use shell size 9 insert
• Termination Method: Both employ solder cup termination
• Fastening Mechanism: Both utilize push-pull fastening with keyed orientation
• Electrical Ratings: Both support 1A current rating and 30VAC/42VDC voltage specifications
• Operating Temperature: Both operate within -25°C to 85°C range
• Contact Material & Finish: Both feature gold-plated mating surfaces on phosphor bronze contacts
• Compliance Status: Both are RoHS3 compliant and REACH affected

The HR25A variant represents an evolution within the HR25 series, maintaining full mechanical and electrical compatibility while offering enhanced features including backshell, clamp, and strain relief components.

Parameter Comparison

Engineering Selection Recommendations

The HR25A-9P-16P is a qualified substitute for the HR25-9P-16P(72) in applications where the following conditions are met:

• Design specifications require a 16-position circular connector plug with male pins and solder cup termination
• Operating parameters fall within the specified electrical and temperature ranges
• RoHS3 compliance is required for the application
• The enhanced mechanical features (backshell, clamp, strain relief) of the HR25A variant are compatible with the end-use assembly

Both parts maintain identical core electrical and mechanical specifications. The HR25A-9P-16P is currently in active production status with confirmed inventory availability. Selection between these parts should be based on supply availability, cost considerations, and whether the additional mechanical features of the HR25A variant provide value for the specific application.

Frequently Asked Questions (FAQ)

Q: What determines compatibility between the HR25-9P-16P(72) and HR25A-9P-16P?

A: Compatibility is established through matching connector type (plug with male pins), position count (16), shell size (9), termination method (solder cup), fastening mechanism (push-pull), and electrical ratings (1A current, 30VAC/42VDC voltage, -25°C to 85°C operating range). Both parts meet these criteria.

Q: Can the HR25A-9P-16P be used as a direct replacement in existing assemblies?

A: Yes, the HR25A-9P-16P maintains full mechanical and electrical compatibility with the HR25-9P-16P(72). The solder cup termination and connector geometry are identical, allowing direct substitution in PCB assembly and wiring applications.

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

A: The HR25A represents an enhanced variant within the HR25 circular connector family. While maintaining identical core specifications, the HR25A includes integrated backshell, clamp, and strain relief features. Both series use identical shell sizes, position counts, and electrical ratings.

Q: Are there packaging differences between these parts?

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

Q: What compliance certifications apply to both parts?

A: The HR25A-9P-16P carries RoHS3 compliance and is REACH affected. Compliance status for the HR25-9P-16P(72) is not specified in the available technical documentation. Verify compliance requirements for your specific application before selection.

Q: How do the contact materials compare?

A: The HR25A-9P-16P uses phosphor bronze contacts with 8.00µin (0.203µm) gold plating on mating surfaces. Contact material specifications for the HR25-9P-16P(72) are not provided. Both parts feature gold-plated mating surfaces suitable for industrial applications.
