SMR2450 Equivalent & Substitute Parts

Part Overview

The SMR2450 is a solid state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (1 Form A) hockey puck design. This component is rated for 50A load current with AC output capability and zero-cross switching, operating across input voltages of 8–32VDC and load voltages of 60–280V. The SMR2450 is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMR2450 is determined by strict equivalence across the following critical parameters:

• Input voltage range: 8–32VDC
• Load voltage range: 60–280V
• Load current rating: 50A
• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC with zero-cross switching
• Package form factor: Hockey Puck
• Mounting type: Chassis Mount
• Termination style: Screw Terminal

The SMR2450-6 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is product status: SMR2450-6 is active and currently available, whereas SMR2450 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The SMR2450-6 is the direct substitute for the obsolete SMR2450. Both components share identical electrical ratings and mechanical form factors. Selection of SMR2450-6 is supported by its active product status, ensuring availability and ongoing manufacturer support. The SMR2450-6 carries ROHS3 compliance certification, meeting current regulatory requirements for electronic component manufacturing and distribution.

Frequently Asked Questions (FAQ)

Q: Can SMR2450-6 be used as a direct replacement for SMR2450? A: Yes. Both components share identical input voltage (8–32VDC), load voltage (60–280V), load current (50A), circuit configuration (SPST-NO), output type (AC, zero-cross), mounting type (chassis mount), termination style (screw terminal), and package form factor (hockey puck).

Q: Why is SMR2450 listed as obsolete? A: SMR2450 has been discontinued by the manufacturer. SMR2450-6 is the active equivalent and recommended for new designs and replacement applications.

Q: Are there physical differences between SMR2450 and SMR2450-6? A: Both components use the hockey puck package form factor and chassis mount configuration. No mechanical incompatibilities exist between the two parts.

Q: What compliance certifications apply to SMR2450-6? A: SMR2450-6 is ROHS3 compliant and carries CE approval. REACH compliance status is unaffected for both parts.

Q: Can these relays be used interchangeably in existing systems? A: Yes, provided the system design accommodates the specified input voltage range (8–32VDC), load voltage range (60–280V), and 50A load current rating. Screw terminal connections and chassis mount configuration remain consistent between both parts.
