HE4HNWPR/03 Equivalent & Substitute Parts

Part Overview

The HE4HNWPR/03 is a 3-position, 10mm pitch Eurostyle terminal block manufactured by Altech Corporation, rated for 30A at 60V. This component is classified as a circuit connector and terminal block assembly designed for industrial control and power distribution applications. The part maintains Active product status with 1158 units in current inventory stock.

Terminal blocks of this specification are essential in applications requiring reliable electrical connections with standardized pitch spacing and current-carrying capacity. Substitute parts become necessary when original manufacturer stock is unavailable, when supply chain optimization is required, or when design flexibility permits equivalent alternatives meeting identical electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HE4HNWPR/03 is determined by the following critical parameters:

• Terminal Block Type: Eurostyle Terminal Strip configuration
• Number of Circuits: 3-position requirement
• Pitch Spacing: 10mm (0.394") standardized spacing
• Current Rating: 30A minimum capacity
• Voltage Rating: 60V or higher
• Termination Method: Screw-based top termination
• Packaging Format: Bulk supply
• Compliance: RoHS and REACH status alignment

The substitute part 1776296-3 (TE Connectivity AMP Connectors) meets all critical substitution criteria. Both components share identical circuit count, pitch spacing, current rating, and terminal block classification. The substitute maintains equivalent electrical performance and mechanical compatibility within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the HE4HNWPR/03 and 1776296-3 maintain Active product status, ensuring continued manufacturer support and supply availability. The Altech component carries ROHS3 Compliant certification, while the TE Connectivity substitute carries RoHS Compliant status—both meeting current regulatory requirements for electronic component manufacturing.

The TE Connectivity 1776296-3 provides a voltage rating of 250V, which exceeds the 60V specification of the original part. This higher voltage rating does not create incompatibility; it represents an enhanced safety margin for applications operating within the original 60V specification envelope.

Selection between these components should be based on:

• Availability and lead time requirements
• Supply chain preferences and established vendor relationships
• Inventory management and stock rotation policies
• Cost considerations within procurement budgets
• Existing design documentation and qualification history

Both components satisfy the electrical and mechanical requirements for direct substitution in applications specified for the HE4HNWPR/03.

Frequently Asked Questions (FAQ)

Q: Can the 1776296-3 directly replace the HE4HNWPR/03 in existing designs?

A: Yes. Both components share identical circuit count (3), pitch spacing (10mm), current rating (30A), and terminal block type (Eurostyle). The screw-based termination method is identical. No design modification is required.

Q: What is the significance of the voltage rating difference (60V vs. 250V)?

A: The substitute part carries a higher voltage rating. This does not create incompatibility. Applications designed for 60V operation remain fully compatible with a component rated for 250V. The higher rating provides additional safety margin without affecting performance in the original application envelope.

Q: Are there compliance differences between these parts?

A: Both components are RoHS compliant. The original part carries ROHS3 Compliant certification; the substitute carries RoHS Compliant status. Both meet current regulatory requirements for electronic component manufacturing and distribution.

Q: What packaging format is used for both components?

A: Both the HE4HNWPR/03 and 1776296-3 are supplied in Bulk packaging format, consistent with industrial terminal block distribution standards.

Q: Are both components currently in active production?

A: Yes. Both components maintain Active product status with current manufacturer support and availability through authorized distribution channels.

Q: What termination method do both components use?

A: Both components utilize screw-based top termination for wire connection, providing consistent installation procedures and mechanical reliability across substitution.
