NTD2425 Solid State Relay SPST-NO 25A 24-280V

Part Overview

The NTD2425 is a solid state relay (SSR) with SPST-NO (Single Pole Single Throw - Normally Open) configuration, rated for 25A load current and 24V to 280V AC output. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing system maintenance. The part features a hockey puck form factor with screw terminal connections, designed for chassis mount applications requiring zero-cross switching capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the NTD2425 is determined by strict equivalence across the following electrical and mechanical parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC with zero-cross switching
• Input voltage range: 3 ~ 32VDC
• Load voltage range: 24 V ~ 280 V
• Load current rating: 25 A
• Mounting type: Chassis Mount
• Package form factor: Hockey Puck
• Termination: Screw Terminal

Both substitute parts (84134010 and D2425) meet all these criteria and are manufactured by Sensata-Crydom. The substitutes differ from the main part in product status (active vs. obsolete) and regulatory compliance certifications, but maintain identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are direct functional equivalents to the NTD2425 and are suitable for replacement in applications requiring identical electrical and mechanical specifications. The primary distinction between substitutes lies in regulatory compliance and product lifecycle status.

Part 84134010 (GN series) and part D2425 (Series 1) are both active products with ROHS3 compliance and REACH affected status, making them appropriate for new designs and systems subject to environmental regulations. The NTD2425, being obsolete, should be replaced with either substitute in ongoing production or maintenance scenarios.

Selection between the two active substitutes should be based on supply chain availability and internal design documentation requirements, as both parts are electrically and mechanically identical.

Frequently Asked Questions (FAQ)

Q: Can NTD2425 be directly replaced with 84134010 or D2425?

A: Yes. Both substitute parts are direct replacements. They maintain identical electrical ratings (25A at 24-280V AC), input voltage range (3-32VDC), circuit configuration (SPST-NO), output type (AC zero-cross), mounting type (chassis mount), package form (hockey puck), and termination style (screw terminal).

Q: What is the difference between 84134010 and D2425?

A: Both parts are functionally equivalent. The differences are in series designation (GN vs. 1) and HTSUS classification codes. Electrical performance and mechanical compatibility are identical. Selection should be based on supply availability and internal documentation requirements.

Q: Why is NTD2425 listed as obsolete?

A: Product obsolescence indicates the part is no longer in active production. Substitutes 84134010 and D2425 are active products from the same manufacturer and provide continued availability for equivalent functionality.

Q: Are there any compliance differences between the parts?

A: NTD2425 is REACH Unaffected, while both substitutes (84134010 and D2425) are REACH Affected and ROHS3 Compliant. For applications subject to environmental regulations, the active substitutes are the appropriate choice.

Q: Does the hockey puck package form factor remain the same across all three parts?

A: Yes. All three parts use the hockey puck package with screw terminal connections and chassis mount configuration, ensuring mechanical compatibility in existing designs.
