CD4825W2V Solid State Relay - Equivalent & Substitute Parts

Part Overview

The CD4825W2V is an active solid state relay (SSR) manufactured by Sensata Technologies, configured as a dual SPST-NO (1 Form A x 2) switching module in Hockey Puck packaging. This component is designed for AC load switching applications with zero-cross detection, operating from 4–32VDC input control voltage and supporting loads from 48–660V AC at 25A per channel. The part is RoHS Compliant and remains in active production status. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative configurations within specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the CD4825W2V is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) x 2 dual-channel topology
• Output Type: Must support AC switching with zero-cross detection
• Input Voltage Range: Control voltage must accommodate 4–32VDC operation
• Load Voltage Range: Must support minimum 48V and maximum 660V AC loads
• Load Current: Must support minimum 25A per channel
• Termination Style: Screw Terminal connection required for direct compatibility
• Mounting Type: Chassis Mount configuration
• RoHS Compliance: Must meet RoHS or ROHS3 standards

Two substitute parts meet these criteria with specific parameter variations:

84140603N (Crouzet GN2 Series): Exceeds load current specification (50A vs. 25A), maintains identical voltage ranges, input control voltage, and zero-cross AC output. Packaging differs (Module vs. Hockey Puck). Mounting flexibility includes both Chassis and Panel Mount options. ROHS3 Compliant.

ASR-SID480D25ZL (Altran Magnetics SID Series): Matches load current (25A), reduces input voltage range (4–15VDC vs. 4–32VDC), reduces load voltage range (24–530V vs. 48–660V), and uses Quick Connect termination (0.250" vs. Screw Terminal). Module packaging. ROHS3 Compliant.

Parameter Comparison

Engineering Selection Recommendations

84140603N (Crouzet GN2) is suitable for applications where the CD4825W2V is unavailable and the design permits higher load current capacity (50A). This part maintains full voltage compatibility across both input control and AC load ranges. The increased current rating provides design margin without reducing performance. Module packaging and dual mounting options (Chassis/Panel) offer installation flexibility. ROHS3 compliance exceeds the original RoHS requirement. Screw Terminal termination ensures direct wiring compatibility.

ASR-SID480D25ZL (Altran Magnetics SID) is suitable only for applications where the design operates within reduced voltage specifications: input control voltage limited to 4–15VDC and AC load voltage limited to 24–530V. This part matches the 25A load current rating. Quick Connect termination (0.250") requires wiring adaptation from Screw Terminal connections. ROHS3 compliance meets environmental standards. Use this substitute only when voltage constraints are confirmed within the reduced operating range.

Frequently Asked Questions (FAQ)

Q: Can the 84140603N directly replace the CD4825W2V without circuit modification?

A: Yes, for applications operating within the CD4825W2V voltage specifications (4–32VDC input, 48–660V load). The 84140603N maintains identical voltage ranges and input control voltage. The higher 50A current rating does not prevent operation at 25A loads. Screw Terminal termination is identical. Physical packaging differs (Module vs. Hockey Puck), requiring mechanical mounting verification.

Q: Is the ASR-SID480D25ZL a direct substitute?

A: No. This part operates within reduced voltage ranges: 4–15VDC input (vs. 4–32VDC) and 24–530V load (vs. 48–660V). Use only if your application operates entirely within these lower voltage limits. Quick Connect termination differs from Screw Terminal, requiring wiring reconfiguration.

Q: What is the impact of different package types (Hockey Puck vs. Module)?

A: Package type affects mechanical mounting, thermal dissipation characteristics, and physical footprint. Hockey Puck and Module configurations have different dimensional envelopes and mounting hole patterns. Verify mechanical compatibility with your chassis or panel mounting structure before substitution.

Q: Do all three parts support zero-cross AC switching?

A: Yes. All three parts (CD4825W2V, 84140603N, and ASR-SID480D25ZL) are configured for AC output with zero-cross detection, ensuring synchronized switching at AC voltage zero-crossings to minimize EMI and switching transients.

Q: Are there compliance differences between the parts?

A: The CD4825W2V is RoHS Compliant. Both substitutes (84140603N and ASR-SID480D25ZL) are ROHS3 Compliant, which represents a more stringent environmental standard. All three parts carry EAR99 ECCN classification and 8536.41.0060 HTSUS code.

Q: What termination style differences exist?

A: CD4825W2V and 84140603N use Screw Terminal connections, allowing direct wiring compatibility. ASR-SID480D25ZL uses Quick Connect – 0.250" (6.3mm) termination, requiring terminal adapters or wiring reconfiguration for integration into existing Screw Terminal systems.
