NTA2410 Solid State Relay - Equivalent & Substitute Parts

Part Overview

The NTA2410 is a solid state relay (SSR) with SPST-NO (Single Pole Single Throw - Normally Open) configuration manufactured by Sensata-Crydom. This hockey puck-style relay is designed for AC load switching applications with a 10A capacity across a 24V to 280V load voltage range and 90V to 140VAC input control voltage. The NTA2410 is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NTA2410 is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC, Zero Cross
• Load current rating: 10 A
• Load voltage range: 24 V ~ 280 V
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Package type: Hockey Puck

The identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional compatibility in applications originally designed for the NTA2410. Variations in input voltage range, product status, compliance certifications, and series designation do not affect substitutability when the above parameters are matched.

Parameter Comparison

Engineering Selection Recommendations

Both A2410 and 84134001 are functionally equivalent substitutes for the NTA2410 based on electrical and mechanical parameter matching.

A2410 is the preferred substitute when REACH compliance is required for applications subject to European regulatory frameworks. This part carries ROHS3 Compliant status and is REACH Affected, indicating full compliance with current EU chemical regulations. The A2410 maintains active product status with 2196 units in stock, ensuring supply continuity.

84134001 is suitable for applications requiring RoHS Compliant certification and MSL Level 1 moisture sensitivity rating. This part is manufactured by Sensata Technologies and carries active product status with 828 units in stock. The expanded input voltage range (90 ~ 280VAC versus 90 ~ 140VAC on the NTA2410) provides additional operational flexibility.

Both substitutes are classified as active products, eliminating the obsolescence risk associated with the original NTA2410.

Frequently Asked Questions (FAQ)

Q: Can A2410 and 84134001 be used interchangeably with NTA2410?

A: Yes. Both parts maintain identical circuit configuration (SPST-NO), output type (AC, Zero Cross), load current (10A), load voltage range (24V–280V), mounting type (Chassis Mount), termination style (Screw Terminal), and package type (Hockey Puck). These parameters define functional compatibility.

Q: What is the difference between the input voltage ranges?

A: The NTA2410 accepts 90–140VAC input, while A2410 and 84134001 accept 90–280VAC input. The expanded range on the substitutes does not affect compatibility; the NTA2410's narrower range is a subset of the substitute ranges.

Q: Are there compliance differences between the substitutes?

A: Yes. A2410 is ROHS3 Compliant and REACH Affected. 84134001 is RoHS Compliant with MSL Level 1 rating. Selection should align with application-specific regulatory requirements.

Q: Does the hockey puck package type affect substitution?

A: No. All three parts use identical hockey puck chassis mount packaging with screw terminal connections, ensuring mechanical and electrical interface compatibility.

Q: Why is the NTA2410 listed as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The active substitutes A2410 and 84134001 provide equivalent functionality with ongoing supply availability.
