CSE2450 Solid State Relay SPST-NO 50A 24-280V Equivalent & Substitute Parts

Part Overview

The CSE2450 is a solid state relay (SSR) manufactured by Sensata-Crydom, configured as a single-pole single-throw normally open (SPST-NO) device rated for 50A load current and 24-280V output voltage range. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The part features a hockey puck form factor with screw terminal connections, designed for chassis mount applications requiring AC zero-cross switching capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSE2450 is determined by the following critical parameters: circuit configuration (SPST-NO), output type (AC zero-cross), mounting type (chassis mount), termination style (screw terminal), and package form factor (hockey puck or equivalent module). Load current and voltage ranges define the operational envelope; substitute parts must meet or exceed the original specifications or operate within compatible ranges for the intended application.

The substitute parts identified fall into two categories:

Direct Sensata-Crydom Substitutes (Same Manufacturer): D2450 and 84134020 maintain identical circuit configuration, output type, mounting, and termination. Both are active products with enhanced input voltage range (3-32VDC vs. 15-32VDC) and improved compliance status.

Cross-Manufacturer Substitutes: AQN611 (Panasonic Electric Works) and ASR-SN240D60ZW-L (Altran Magnetics) provide equivalent SPST-NO functionality with AC zero-cross switching. These parts differ in load current and voltage specifications, requiring application-level compatibility verification.

Parameter Comparison

Engineering Selection Recommendations

D2450 (Sensata-Crydom): This is the primary direct substitute for CSE2450. It maintains identical electrical specifications (50A, 24-280V) and physical form factor while offering improved input voltage range (3-32VDC) and active product status. RoHS3 compliance and REACH affected status indicate current manufacturing standards. This part is recommended for direct replacement in existing designs.

84134020 (Sensata-Crydom): This manufacturer-recommended substitute provides identical load specifications and active product status. It differs from D2450 in series designation (GN vs. 1) and MSL rating (1 vs. not specified). RoHS3 compliance and REACH affected status align with modern regulatory requirements. This part is suitable for applications requiring enhanced moisture sensitivity control.

AQN611 (Panasonic Electric Works): This cross-manufacturer substitute operates at 40A load current and 75-250V output voltage range, representing a reduced current capacity and narrower voltage envelope compared to CSE2450. Input voltage range (4-32VDC) is compatible. This part is applicable only to applications where 40A current and 75-250V voltage range are sufficient. RoHS compliance and active status support long-term availability.

ASR-SN240D60ZW-L (Altran Magnetics, LLC): This substitute provides 60A load current capacity but operates at a fixed 24V output voltage range, eliminating the wide voltage flexibility of CSE2450. Input voltage range (3-32VDC) is compatible. This part is suitable only for dedicated 24V AC applications requiring higher current capacity. Module form factor differs from hockey puck configuration. RoHS3 compliance and active status ensure regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can D2450 be used as a direct replacement for CSE2450?

A: Yes. D2450 maintains identical circuit configuration (SPST-NO), output type (AC zero-cross), load specifications (50A, 24-280V), mounting type (chassis mount), package form (hockey puck), and termination style (screw terminal). The improved input voltage range (3-32VDC vs. 15-32VDC) provides additional design flexibility. D2450 is the recommended substitute.

Q: What is the difference between D2450 and 84134020?

A: Both parts are Sensata-Crydom SPST-NO relays with identical load specifications (50A, 24-280V) and active product status. The primary differences are series designation (1 vs. GN) and moisture sensitivity level (not specified vs. 1). Both are suitable substitutes; selection depends on application-specific moisture sensitivity requirements.

Q: Can AQN611 replace CSE2450 in all applications?

A: No. AQN611 operates at 40A load current and 75-250V output voltage range, both reduced from CSE2450 specifications (50A, 24-280V). This substitute is applicable only to applications where these reduced specifications are compatible with system requirements.

Q: Is ASR-SN240D60ZW-L suitable for applications requiring variable output voltage?

A: No. ASR-SN240D60ZW-L operates at a fixed 24V output voltage range, eliminating the 24-280V flexibility of CSE2450. This substitute is limited to dedicated 24V AC applications. The module form factor also differs from the hockey puck configuration.

Q: What compliance certifications should I verify for substitute parts?

A: All identified substitutes carry RoHS compliance certifications (RoHS3 or equivalent), ensuring environmental and hazardous substance compliance. REACH status varies: D2450 and 84134020 are REACH affected (current manufacturing), while AQN611 and ASR-SN240D60ZW-L have specified REACH status. Verify REACH compliance requirements for your specific regulatory jurisdiction.

Q: Are there packaging differences between substitute parts?

A: D2450, 84134020, and AQN611 maintain the hockey puck form factor with screw terminal connections. ASR-SN240D60ZW-L uses a module form factor. Verify mechanical fit and mounting compatibility with your application before selection.
