Substitute Part Grouping Explanation

Substitution eligibility for the NDN1A-WH is determined by strict equivalence across the following critical parameters:

• Terminal Block Type: Barrier Block
• Number of Circuits: 1
• Number of Wire Entries: 2
• Current Rating: 90A
• Voltage Rating: 600V
• Wire Gauge Compatibility: 2-18 AWG
• Top Termination Method: Screws
• Bottom Termination: Closed
• Barrier Type: Enclosed
• Terminal Screw Material: Steel
• Terminal Screw Finish: Zinc
• Mounting Type: Channel, DIN Rail, Track
• Operating Temperature: 105°C
• Insulation Material: Thermoplastic
• Flammability Rating: UL94 V-2

The NDN1-WH meets all substitution criteria as an active product within the same Magnum® NDN series, maintaining identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The NDN1-WH is the direct substitute for the obsolete NDN1A-WH. Both components are manufactured by Eaton - Bussmann Electrical Division and belong to the Magnum® NDN series. The NDN1-WH maintains identical electrical ratings (90A, 600V), mechanical configuration (1 circuit, 2 wire entries, screw termination), and thermal specifications (105°C operating temperature).

The primary distinction is product status: NDN1A-WH is obsolete while NDN1-WH is active and currently in production. The NDN1-WH additionally carries RoHS compliance certification, meeting modern regulatory requirements. Both components satisfy UL94 V-2 flammability standards and are suitable for channel, DIN rail, and track mounting applications.

Frequently Asked Questions (FAQ)

Q: Can NDN1-WH replace NDN1A-WH in existing installations?

A: Yes. The NDN1-WH is electrically and mechanically equivalent to the NDN1A-WH across all critical parameters: current rating (90A), voltage rating (600V), wire gauge compatibility (2-18 AWG), termination method (screws), and mounting configuration. Direct substitution is supported.

Q: What is the difference between NDN1A-WH and NDN1-WH?

A: The components are functionally identical. The primary difference is product lifecycle status: NDN1A-WH is obsolete, while NDN1-WH is an active product. The NDN1-WH also carries RoHS compliance certification.

Q: Are there packaging differences between these parts?

A: The NDN1A-WH packaging specification is not provided. The NDN1-WH is supplied in bulk packaging. Verify packaging requirements for your application.

Q: Do both parts meet the same safety standards?

A: Yes. Both the NDN1A-WH and NDN1-WH meet UL94 V-2 flammability requirements and are rated for 600V operation at 105°C maximum operating temperature.

Q: Is the NDN1-WH suitable for new designs?

A: Yes. The NDN1-WH is an active product with RoHS compliance, making it appropriate for new installations and designs requiring modern regulatory compliance.
