A4808-10 Equivalent & Substitute Parts

Part Overview

The A4808-10 is a solid state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (1 Form A) device in a hockey puck package. This component is designed for AC output switching applications with a rated load current of 8A and operates across a load voltage range of 80V to 530V. The device is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the A4808-10 is determined by the following critical parameters that must remain consistent:

• Manufacturer & Series: Sensata-Crydom A48 series maintains electrical and mechanical compatibility
• Circuit Configuration: SPST-NO (1 Form A) topology must be preserved
• Output Type: AC output switching capability
• Input Voltage Range: 90 ~ 280VAC control signal compatibility
• Load Voltage Range: 80 V ~ 530 V operational envelope
• Mounting & Termination: Chassis mount with screw terminal interface
• Package Type: Hockey puck form factor for mechanical fit

The A4825-10 qualifies as a direct substitute based on these parameters. While the load current rating differs (25A versus 8A), this represents an uprated capability within the same product family and does not prevent substitution in applications requiring the 8A rating.

Parameter Comparison

Engineering Selection Recommendations

The A4825-10 is the designated substitute for the obsolete A4808-10. Selection is based on the following factors:

• Product Status: The A4825-10 maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity.
• Compliance: The A4825-10 is RoHS compliant, meeting current regulatory requirements for electronic components in regulated markets.
• Electrical Compatibility: Both devices operate within identical input voltage (90 ~ 280VAC), load voltage (80 V ~ 530 V), and circuit configuration parameters.
• Mechanical Compatibility: Identical mounting type (chassis mount), termination style (screw terminal), and package form factor (hockey puck) ensure direct physical replacement without redesign.
• Current Rating: The A4825-10 provides a higher load current rating (25A) compared to the A4808-10 (8A). This uprated capability is suitable for applications originally designed for 8A operation.

Frequently Asked Questions (FAQ)

Q: Can the A4825-10 be used as a direct replacement for the A4808-10?

A: Yes. Both devices share identical circuit configuration (SPST-NO), input voltage range (90 ~ 280VAC), load voltage range (80 V ~ 530 V), mounting type (chassis mount), termination style (screw terminal), and package form factor (hockey puck). The A4825-10 is rated for higher load current (25A versus 8A), which does not prevent substitution in applications requiring 8A operation.

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

A: The load current rating differs. The A4808-10 is rated for 8A, while the A4825-10 is rated for 25A. Both operate across the same voltage ranges and share identical electrical and mechanical interfaces.

Q: Will the A4825-10 fit in the same mounting location as the A4808-10?

A: Yes. Both devices use the hockey puck package form factor with chassis mount configuration and screw terminal termination, ensuring mechanical compatibility without modification.

Q: Is the A4825-10 compliant with current regulations?

A: Yes. The A4825-10 is RoHS compliant and maintains active product status with current manufacturing support.

Q: Are there any electrical parameter mismatches between these parts?

A: No. The input voltage range (90 ~ 280VAC), load voltage range (80 V ~ 530 V), circuit configuration (SPST-NO), and output type (AC) are identical across both devices.
