Equivalent & Substitute Parts for D4825-10

Part Overview

The D4825-10 is a solid state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (1 Form A) hockey puck configuration. This AC output relay is rated for 25A load current with an input voltage range of 3–32VDC and a load voltage range of 80–530V. The component is actively produced and RoHS compliant, designed for chassis mount applications with screw terminal termination. Equivalent and substitute parts are identified based on matching core electrical parameters: SPST-NO circuit topology, 25A load current rating, compatible input voltage range, overlapping load voltage specifications, AC output type, and identical mechanical packaging.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the D4825-10 are qualified based on the following criteria:

Core Electrical Parameters (Non-Negotiable):

• Circuit topology: SPST-NO (1 Form A)
• Load current rating: 25A
• Output type: AC
• Input voltage range: minimum 3–4VDC, maximum 32VDC
• Load voltage range: must overlap with or extend the 80–530V specification
• Mechanical form factor: Hockey Puck chassis mount with screw terminals

Compliance & Status:

• Product status: Active
• RoHS compliance: RoHS Compliant or ROHS3 Compliant

The following substitute parts meet these criteria:

1. 84134310 (Sensata-Crydom, GN Series): Load voltage 48–660V, input 4–32VDC, ROHS3 Compliant
2. 84137210N (Crouzet, GN Series): Load voltage 24–280V, input 4–32VDC, RoHS Compliant
3. ASR-SI480D25RW-L (Altran Magnetics LLC, SI Series): Load voltage 48–530V, input 4–32VDC, ROHS3 Compliant

Parameter Comparison

Engineering Selection Recommendations

84134310 (Sensata-Crydom): This substitute extends the load voltage range to 660V maximum, providing broader application coverage than the D4825-10. The minimum input voltage increases to 4VDC. ROHS3 compliance and REACH Affected status apply. Suitable for applications requiring higher load voltage tolerance.

84137210N (Crouzet): This substitute operates within a narrower load voltage range (24–280V) compared to the D4825-10 (80–530V). Selection is appropriate only for applications with load voltages between 80–280V. RoHS Compliant and REACH Unaffected. Minimum input voltage is 4VDC.

ASR-SI480D25RW-L (Altran Magnetics LLC): This substitute maintains the 48–530V load voltage range, closely matching the D4825-10 specification. Input voltage range is 4–32VDC. ROHS3 Compliant and REACH Unaffected. Represents the closest electrical equivalent to the original part.

All substitute parts maintain identical load current (25A), circuit topology (SPST-NO), output type (AC), mechanical form factor (Hockey Puck), and termination style (Screw Terminal). Selection depends on specific load voltage requirements and compliance mandates of the end application.

Frequently Asked Questions (FAQ)

Q: Can 84137210N replace D4825-10 in all applications?

A: No. The 84137210N load voltage range (24–280V) is narrower than the D4825-10 (80–530V). It is suitable only for applications where the load voltage does not exceed 280V. For applications requiring load voltages above 280V, use 84134310 or ASR-SI480D25RW-L.

Q: What is the minimum input voltage difference between D4825-10 and its substitutes?

A: The D4825-10 operates from 3VDC minimum, while all substitute parts require a minimum of 4VDC. Applications with input voltages below 4VDC cannot use these substitutes.

Q: Are all substitute parts mechanically compatible with D4825-10 mounting?

A: Yes. All substitute parts use identical Hockey Puck chassis mount packaging with screw terminal termination, ensuring direct mechanical compatibility.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both designations indicate compliance with RoHS directives. ROHS3 represents compliance with the most recent RoHS 3 directive (2015/863/EU). Both are acceptable for RoHS-regulated applications.

Q: Which substitute part is the closest electrical equivalent to D4825-10?

A: ASR-SI480D25RW-L provides the closest match, with load voltage range 48–530V overlapping the D4825-10 specification of 80–530V. Input voltage range is identical (4–32VDC after the 3V minimum difference).

Q: Do REACH compliance differences affect substitution?

A: REACH status indicates regulatory applicability in the European Union. The D4825-10 is not listed in this data. Substitute parts marked REACH Affected (84134310) or REACH Unaffected (84137210N, ASR-SI480D25RW-L) should be selected based on end-use geography and regulatory requirements.
