CSE2425 Solid State Relay SPST-NO 25A 24-280V Equivalent & Substitute Parts

Part Overview

The CSE2425 is a solid state relay (SSR) manufactured by Sensata Technologies, configured as a single-pole single-throw normally open (SPST-NO) device with a 25A load capacity and 24-280V output voltage range. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing procurement and system maintenance. Substitute parts must maintain functional equivalence across critical electrical parameters including input voltage tolerance, load voltage range, current rating, and circuit configuration while accommodating minor variations in input voltage specifications and load voltage windows.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSE2425 is determined by strict adherence to the following critical parameters:

Mandatory Equivalence Criteria:

• Circuit configuration must be SPST-NO (1 Form A)
• Output type must be AC with zero-cross switching
• Load current rating must be 25 A
• Package type must be Hockey Puck
• Mounting type must be Chassis Mount
• Termination style must be Screw Terminal

Allowable Variation Parameters:

• Input voltage range: Substitute parts may have lower minimum input voltage (3 VDC acceptable versus 15 VDC minimum on CSE2425) provided maximum remains at or above 32 VDC
• Load voltage range: Substitute parts may have different minimum load voltage (48 V or 75 V acceptable) provided maximum load voltage is 280 V or greater

All identified substitute parts meet these criteria and are classified as active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

D2425 and 84134010 are direct Sensata-Crydom equivalents with identical load voltage range (24-280V) and active product status. Both parts are ROHS3 compliant and represent the most direct functional replacement for the obsolete CSE2425. D2425 offers broader input voltage tolerance (3-32 VDC) compared to the original specification. The 84134010 maintains identical electrical specifications while belonging to the GN series.

Secondary Substitutes (Load Voltage Constraints):

AQN411 (Panasonic Electric Works) maintains all critical electrical parameters but operates within a reduced load voltage window of 75-250V. This part is suitable only for applications where the load voltage does not fall below 75V or exceed 250V. RoHS compliance is confirmed; REACH status is not specified.

ASR-SI240D25ZW-L (Altran Magnetics, LLC) operates within a load voltage range of 48-280V, providing compatibility with applications requiring lower minimum load voltages than AQN411 while maintaining the full 280V maximum. This part is ROHS3 compliant and REACH unaffected, matching the regulatory profile of the original CSE2425.

Compliance Considerations:

All substitute parts maintain the ECCN classification of EAR99. Parts D2425 and 84134010 are REACH affected, whereas ASR-SI240D25ZW-L maintains REACH unaffected status consistent with the original component. Selection should account for supply chain regulatory requirements specific to the application region.

Frequently Asked Questions (FAQ)

Q: Can D2425 directly replace CSE2425 in all applications?

A: Yes. D2425 maintains identical load voltage range (24-280V), load current (25A), circuit configuration (SPST-NO), and output type (AC, zero cross). The lower input voltage minimum (3 VDC versus 15 VDC) provides enhanced compatibility with lower-voltage control circuits. Both are chassis-mount hockey puck packages with screw terminals.

Q: What is the difference between D2425 and 84134010?

A: Both are Sensata-Crydom SPST-NO 25A relays with identical electrical specifications (24-280V load range, 3-32 VDC input range). The primary difference is series designation (1 versus GN) and HTSUS classification. Functionally, they are equivalent for the CSE2425 replacement application.

Q: Why does AQN411 have a different load voltage range?

A: AQN411 is manufactured by Panasonic Electric Works and is specified for 75-250V load operation. This represents a narrower operating window than the CSE2425 (24-280V). AQN411 is suitable only for applications where load voltage remains within the 75-250V band. Applications requiring operation below 75V or above 250V must use alternative substitutes.

Q: Is ASR-SI240D25ZW-L compatible with low-voltage loads?

A: ASR-SI240D25ZW-L operates within a 48-280V load range, making it compatible with applications requiring minimum load voltages of 48V or higher. Applications requiring operation below 48V must use D2425 or 84134010, which support 24V minimum load voltage.

Q: Are all substitute parts RoHS compliant?

A: Yes. D2425 and 84134010 are ROHS3 compliant. AQN411 is RoHS compliant. ASR-SI240D25ZW-L is ROHS3 compliant. All substitutes meet current RoHS requirements.

Q: What packaging options are available?

A: All substitute parts are supplied in hockey puck packages suitable for chassis mounting with screw terminal connections. D2425, 84134010, and AQN411 are supplied in bulk packaging. ASR-SI240D25ZW-L is supplied in box packaging.
