SSR-240D25R Solid State Relay Equivalent & Substitute Parts

Part Overview

The SSR-240D25R is an active solid state relay manufactured by TE Connectivity Potter & Brumfield Relays. This SPST-NO (1 Form A) relay operates as a hockey puck chassis mount component with a 25A load capacity across 24V to 280V AC output. The relay accepts 3V to 32VDC input control signals and utilizes screw terminal connections. With 1040 units currently in stock, this component serves applications requiring solid state switching without mechanical contacts. Identification of equivalent substitute parts becomes necessary when addressing supply chain constraints, compliance requirements, or specific manufacturing certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSR-240D25R is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Circuit configuration must be SPST-NO (1 Form A)
• Output type must be AC
• Load current rating must be 25 A
• Load voltage range must be 24 V ~ 280 V
• Input voltage range must be 3 ~ 32 VDC

Mechanical & Physical Specifications:

• Mounting type must be Chassis Mount
• Package type must be Hockey Puck
• Termination style must be Screw Terminal

Regulatory & Compliance Status:

• Product status must be Active
• ECCN classification must be EAR99
• HTSUS code must be 8536.41.0060
• REACH Affected status applies to all qualified substitutes

Parts meeting all these parameters are classified as direct equivalents and may be selected based on availability, compliance certifications, and inventory status.

Parameter Comparison

Engineering Selection Recommendations

The SSR-240D25R and 84134210 are direct electrical and mechanical equivalents meeting all specified parameters for SPST-NO solid state relay applications with 25A AC switching at 24V to 280V load levels.

Compliance Considerations:

The SSR-240D25R carries RoHS non-compliant status, while the 84134210 (Sensata-Crydom GN series) is ROHS3 compliant. Applications subject to RoHS3 regulatory requirements must utilize the 84134210 substitute. Both parts maintain identical ECCN (EAR99) and HTSUS (8536.41.0060) classifications, indicating equivalent export control and tariff treatment.

Moisture Sensitivity:

The SSR-240D25R specifies Not Applicable for Moisture Sensitivity Level, while the 84134210 is rated MSL 1 (Unlimited). This distinction does not affect substitution eligibility but reflects different manufacturing or packaging approaches between manufacturers.

Inventory & Availability:

Both parts maintain active product status with comparable stock levels (1040 units for SSR-240D25R; 1003 units for 84134210), supporting equivalent supply chain reliability.

Selection Basis:

Choose the SSR-240D25R when RoHS non-compliant components are acceptable and TE Connectivity sourcing is preferred. Select the 84134210 when ROHS3 compliance is mandatory or when Sensata-Crydom supply chain integration is required. Both selections deliver identical electrical performance and mechanical compatibility within the specified application envelope.

Frequently Asked Questions (FAQ)

Q: Can the 84134210 directly replace the SSR-240D25R in existing designs?

A: Yes. Both parts are SPST-NO solid state relays with identical electrical ratings (25A, 24V–280V AC output, 3V–32VDC input), chassis mount configuration, hockey puck package, and screw terminal termination. No circuit modifications are required for substitution.

Q: What is the primary difference between these two parts?

A: The SSR-240D25R is RoHS non-compliant, while the 84134210 is ROHS3 compliant. The 84134210 also specifies MSL 1 (Unlimited) moisture sensitivity versus Not Applicable for the SSR-240D25R. Electrical and mechanical specifications are identical.

Q: Which part should be selected for new designs?

A: For new designs subject to RoHS3 regulations, the 84134210 (Sensata-Crydom) is the appropriate selection. For applications without RoHS3 requirements, either part meets specifications. Verify regulatory requirements for your target market and application.

Q: Are there any package or mounting differences between these relays?

A: No. Both parts use identical hockey puck package geometry, chassis mount configuration, and screw terminal termination. Physical and electrical interfaces are fully compatible.

Q: Do these parts have different export control classifications?

A: No. Both the SSR-240D25R and 84134210 share identical ECCN (EAR99) and HTSUS (8536.41.0060) classifications, indicating equivalent export control and tariff treatment.

Q: What input voltage range do these relays accept?

A: Both relays accept 3V to 32VDC input control signals, supporting a wide range of logic and control circuit voltages.

Q: Can these relays switch DC loads?

A: No. Both parts are specified for AC output only. The output type is AC, limiting application to alternating current loads within the 24V to 280V range.
