Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HR25-9TR-16SC is determined by strict equivalence across the following critical parameters:

• Series designation (HR25)
• Connector type (Receptacle Housing)
• Number of positions (16)
• Shell size - insert (9)
• Mounting configuration (Panel Mount with Bulkhead - Rear Side Nut)
• Shell material and finish (Zinc Alloy, Nickel)
• Shielding requirement (Shielded)
• Operating temperature range (-25°C ~ 85°C)
• Contact type (Crimp)
• Orientation (Keyed)

The HR25-9TR-16SC(71) meets all substitution criteria as a direct equivalent within the HR25 series, with identical mechanical and electrical specifications. The primary distinction is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The HR25-9TR-16SC(71) is the direct functional equivalent for applications currently utilizing the HR25-9TR-16SC. The substitute part maintains identical mechanical and electrical specifications while offering two significant advantages:

1. Active product status ensures continued availability and supply chain reliability
2. RoHS compliance satisfies regulatory requirements for new designs and systems subject to RoHS directives

For legacy system maintenance where the original part number is specified, the HR25-9TR-16SC(71) provides seamless interchangeability. The transition from non-compliant to compliant status does not alter the connector's functional performance or physical compatibility.

Frequently Asked Questions (FAQ)

Q: Can HR25-9TR-16SC(71) be used as a direct replacement for HR25-9TR-16SC?

A: Yes. Both parts are identical in all mechanical and electrical parameters including connector type, position count, shell size, mounting configuration, material composition, and operating temperature range. The primary differences are product status and RoHS compliance.

Q: What is the significance of the "(71)" designation in HR25-9TR-16SC(71)?

A: The "(71)" suffix indicates a packaging variant. HR25-9TR-16SC(71) is supplied in bulk packaging, whereas the original part uses standard packaging. This does not affect the connector's functional specifications or compatibility.

Q: Are there any compatibility concerns when substituting HR25-9TR-16SC with HR25-9TR-16SC(71)?

A: No compatibility concerns exist. Both parts conform to identical specifications for panel mount installation, bulkhead fastening, contact crimp configuration, and keyed orientation. Physical dimensions and electrical performance are equivalent.

Q: Why is RoHS compliance relevant for this substitution?

A: RoHS compliance is mandatory for products sold into regulated markets and for systems subject to environmental directives. The HR25-9TR-16SC(71) meets these requirements, whereas the original part does not. For new designs or systems requiring regulatory compliance, the substitute part is the appropriate selection.

Q: Does the obsolete status of HR25-9TR-16SC affect its performance?

A: Obsolete status indicates the part is no longer manufactured. It does not reflect performance degradation. However, obsolescence creates supply chain risk. The HR25-9TR-16SC(71) maintains active production status, ensuring availability for current and future requirements.
