MP240D4 Solid State Relay - Equivalent & Substitute Parts

Part Overview

The MP240D4 is a Solid State Relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (Single Pole Single Throw - Normally Open) relay in a 4-SIP package. This component is designed for AC load switching applications with zero-cross detection, operating with a 3-32VDC input signal and controlling loads up to 4A at 24-280V AC. The product maintains Active status and is ROHS3 compliant. Equivalent and substitute parts may be required due to inventory constraints, application-specific voltage requirements, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP240D4 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must remain SPST-NO (1 Form A)
• Output type must be AC with zero-cross detection
• Package type must be 4-SIP with PC Pin termination
• Mounting type must be Through Hole
• Load current rating must meet or exceed 4A
• Load voltage range must encompass or exceed 24-280V
• Input voltage range must be compatible with 3-32VDC control signals
• RoHS3 compliance required

Identified Substitutes:

GA8-6B02 (Sensata-Crydom): Meets circuit, output type, package, and mounting requirements. Load current rated at 4.6A (below 4A specification). Input voltage range 3-28VDC (within tolerance). Load voltage range 24-280V (equivalent). Suitable for applications not requiring full 4A capacity.

GNB4D2A (Crouzet): Meets circuit, output type, package, and mounting requirements. Load current rated at 4A (equivalent). Input voltage range 4-30VDC (compatible). Load voltage range 12-460V (exceeds specification). Suitable for applications requiring extended voltage range capability.

Parameter Comparison

Engineering Selection Recommendations

MP240D4 (Primary Selection): Recommended for applications requiring the full 4A load current specification within the 24-280V AC range and 3-32VDC input control range. Active product status with established supply chain. ROHS3 compliant and REACH unaffected.

GA8-6B02 (Sensata-Crydom Alternative): Suitable for applications where load current requirements do not exceed 4.6A. Maintains identical load voltage range (24-280V) and compatible input voltage range (3-28VDC). Same manufacturer as primary part, ensuring consistency in design and performance characteristics. ROHS3 compliant and REACH unaffected.

GNB4D2A (Crouzet Alternative): Suitable for applications requiring extended load voltage capability (12-460V range). Maintains 4A load current rating equivalent to MP240D4. Input voltage range (4-30VDC) is compatible with standard control circuits. ROHS3 compliant and REACH unaffected. Recommended for designs requiring voltage flexibility beyond the standard 24-280V specification.

Frequently Asked Questions (FAQ)

Q: Can GA8-6B02 be used as a direct replacement for MP240D4?

A: GA8-6B02 is compatible with MP240D4 in applications where the load current requirement does not exceed 4.6A. Both parts share identical circuit configuration, output type, package, and load voltage range. The primary difference is the reduced current rating (4.6A vs. 4A). Verify application current requirements before substitution.

Q: What is the key difference between GNB4D2A and MP240D4?

A: GNB4D2A maintains the 4A load current rating and compatible input voltage range but extends the load voltage capability to 12-460V compared to MP240D4's 24-280V range. GNB4D2A is manufactured by Crouzet rather than Sensata-Crydom. Both are ROHS3 compliant and suitable for AC zero-cross switching applications.

Q: Are all substitute parts available in the same 4-SIP package?

A: Yes. MP240D4, GA8-6B02, and GNB4D2A are all configured in 4-SIP packages with PC Pin termination and Through Hole mounting. Package compatibility is maintained across all listed alternatives.

Q: What compliance certifications apply to these parts?

A: All three parts (MP240D4, GA8-6B02, and GNB4D2A) are ROHS3 compliant and REACH unaffected. Moisture Sensitivity Level for MP240D4 and GA8-6B02 is rated as 1 (Unlimited).

Q: Can GNB4D2A handle the full 4A load at 280V?

A: GNB4D2A is rated for 4A load current and supports load voltages up to 460V, which encompasses the 280V specification. The part is suitable for 4A operation within its specified voltage range.
