Key Parameters

Substitute Part Grouping Explanation

The HR10-7P-4S(73) qualifies as a direct substitute based on matching electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Connector type, position count, and shell size remain identical
• Termination method (solder cup) and fastening mechanism (push-pull) are unchanged
• Current rating (2A) and voltage rating (150VAC, 200VDC) are equivalent
• Operating temperature range (-25°C ~ 85°C) is maintained
• Cable opening dimension (0.205" / 5.20mm) is identical
• Keyed orientation and unshielded configuration are preserved

The HR10-7P-4S(73) represents an active production variant of the same connector series with enhanced compliance and material specifications.

Parameter Comparison

Engineering Selection Recommendations

The HR10-7P-4S(73) is the active equivalent for the obsolete HR10-7P-4S. All critical electrical and mechanical parameters are identical, ensuring functional compatibility in existing applications.

The HR10-7P-4S(73) offers improved regulatory compliance. It is ROHS3 compliant, whereas the original part is RoHS non-compliant. The substitute is REACH affected, indicating compliance with REACH regulations. Both parts carry the same ECCN (EAR99) and HTSUS classification.

Material enhancements in the HR10-7P-4S(73) include zinc alloy shell construction with nickel finish, beryllium copper contacts with 8.00µin (0.203µm) gold plating thickness, and polyamide (PA) nylon insert material. The substitute includes integrated backshell with clamp features and is rated for industrial and medical applications.

For new designs and field replacements where the original part is no longer available, the HR10-7P-4S(73) provides direct functional substitution with enhanced compliance and material specifications.

Frequently Asked Questions (FAQ)

Q: Can the HR10-7P-4S(73) be used as a direct replacement for the HR10-7P-4S?

A: Yes. Both connectors share identical electrical ratings (2A, 150VAC/200VDC), mechanical dimensions (4-position, shell size 7, 0.205" cable opening), termination method (solder cup), and fastening mechanism (push-pull keyed). The HR10-7P-4S(73) is the active production variant.

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

A: The primary differences are product status and regulatory compliance. The HR10-7P-4S is obsolete and RoHS non-compliant, while the HR10-7P-4S(73) is active production and ROHS3 compliant. Material specifications differ: the substitute uses zinc alloy shell, beryllium copper contacts, and includes backshell with clamp features.

Q: Are there packaging differences?

A: The original HR10-7P-4S packaging is not specified. The HR10-7P-4S(73) is supplied in bulk packaging.

Q: What is the significance of the (73) designation?

A: The (73) suffix indicates a specific variant within the HR10 series, representing the active production version with updated material specifications and regulatory compliance.

Q: Are both parts suitable for industrial and medical applications?

A: The HR10-7P-4S applications are not specified in the available data. The HR10-7P-4S(73) is rated for industrial and medical applications.
