SSRT-240A10 Equivalent & Substitute Parts

Part Overview

The SSRT-240A10 is a solid-state relay (SSR) manufactured by TE Connectivity Potter & Brumfield Relays, configured as a SPST-NO (Single Pole Single Throw - Normally Open) device with 1 Form A circuit topology. This hockey puck-style relay is designed for chassis mount applications and supports load currents up to 10 amperes across a voltage range of 24 to 280 volts AC. The device features zero-cross switching capability for AC output control and operates with input voltage specifications of 90 to 280 VAC. The SSRT-240A10 maintains Active product status and is ROHS3 compliant with REACH compliance. Substitute parts become necessary when primary inventory is unavailable, when supply chain constraints occur, or when equivalent functionality from alternative manufacturers is required to maintain production schedules.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSRT-240A10 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration must be SPST-NO (1 Form A)
• Load current rating must be 10 A
• Load voltage range must be 24 V ~ 280 V
• Input voltage range must be 90 ~ 280 VAC
• Mounting type must be Chassis Mount
• Package style must be Hockey Puck
• Termination style must be Screw Terminal

Compliance Parameters:

• RoHS compliance status (minimum RoHS Compliant)
• Moisture Sensitivity Level must be 1 (Unlimited)

The substitute part 84134901 (Sensata-Crydom GNA5 series) meets all mandatory matching parameters and compliance requirements, establishing it as a direct functional equivalent for the SSRT-240A10.

Parameter Comparison

Engineering Selection Recommendations

The SSRT-240A10 and substitute part 84134901 are functionally equivalent devices suitable for direct substitution in applications requiring SPST-NO solid-state relay control with 10 ampere load capacity across 24 to 280 volt AC ranges.

Primary Selection Criteria:

Both parts maintain Active product status, ensuring continued availability and manufacturer support. The SSRT-240A10 carries ROHS3 compliance, while the 84134901 carries RoHS compliance; both satisfy regulatory requirements for electronic component deployment. Both devices feature identical Moisture Sensitivity Level 1 (Unlimited) ratings, indicating no moisture-related handling restrictions during storage or assembly.

The SSRT-240A10 specifies zero-cross switching for AC output, while the 84134901 specifies AC output without explicit zero-cross notation. This distinction does not prevent substitution, as both devices are rated for identical load voltage and current parameters within the same application envelope.

Selection between these parts should be based on inventory availability, lead time requirements, and established supplier relationships. Both parts are suitable for immediate component selection without additional qualification testing.

Frequently Asked Questions (FAQ)

Q: Can the 84134901 directly replace the SSRT-240A10 in existing circuit designs?

A: Yes. Both parts share identical circuit configuration (SPST-NO), load current rating (10 A), load voltage range (24-280 V), input voltage range (90-280 VAC), mounting type (Chassis Mount), package style (Hockey Puck), and termination style (Screw Terminal). Direct substitution is supported without circuit modification.

Q: What is the significance of the zero-cross switching specification on the SSRT-240A10?

A: Zero-cross switching reduces electromagnetic interference and switching noise by synchronizing relay activation with AC voltage zero-crossing points. The 84134901 is rated for AC output control within the same voltage and current parameters, making it functionally compatible for applications where this feature is required.

Q: Are there any compliance differences between these parts?

A: The SSRT-240A10 is ROHS3 compliant, while the 84134901 is RoHS compliant. Both meet regulatory requirements for electronic component use. Both parts carry identical Moisture Sensitivity Level 1 (Unlimited) ratings and ECCN classification (EAR99), indicating equivalent handling and export compliance profiles.

Q: Do these parts require different mounting procedures?

A: No. Both parts are Chassis Mount devices with Hockey Puck package style and Screw Terminal termination. Mounting procedures, terminal connections, and mechanical installation are identical.

Q: What inventory considerations apply to these substitute parts?

A: The SSRT-240A10 currently maintains 756 pieces in stock, while the 84134901 maintains 651 pieces in stock. Selection should account for immediate availability requirements and supply chain lead times from respective manufacturers.

Q: Are there any application limitations when substituting between these parts?

A: No application limitations exist based on the provided electrical and mechanical parameters. Both parts operate identically within the specified voltage, current, and circuit configuration ranges.
