SSRT-240D10 Equivalent & Substitute Parts

Part Overview

The SSRT-240D10 is a solid-state relay (SSR) manufactured by TE Connectivity Potter & Brumfield Relays, configured as a SPST-NO (1 Form A) device in a hockey puck package. This component is designed for AC load switching applications with a 10 A load current capacity across a 24 V to 280 V operating range. The device accepts a 3 V to 32 VDC control input and incorporates zero-cross switching functionality. The SSRT-240D10 maintains active product status and is available in bulk packaging with 995 units currently in stock. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility is required within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSRT-240D10 is determined by strict alignment with the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Circuit configuration must be SPST-NO (1 Form A)
• Load current rating must be 10 A
• Load voltage range must span 24 V to 280 V
• Input voltage range must accommodate 3 V to 32 VDC
• Output type must be AC

Mechanical Compatibility Criteria:

• Mounting type must be Chassis Mount
• Package must be Hockey Puck
• Termination style must be Screw Terminal

The substitute part 84134900 (Sensata-Crydom GNA5 series) meets all electrical and mechanical parameters specified above, establishing it as a direct functional equivalent. Both parts operate within identical voltage and current specifications and share the same physical form factor and termination interface.

Parameter Comparison

Engineering Selection Recommendations

Both the SSRT-240D10 and 84134900 are active products with identical electrical and mechanical specifications, making them functionally interchangeable within the defined parameter set. Selection between these parts should be based on the following considerations:

Regulatory Compliance: The 84134900 (Sensata-Crydom) carries ROHS3 compliance, while the SSRT-240D10 (TE Connectivity) is RoHS non-compliant. Applications subject to RoHS3 requirements must use the 84134900 substitute.

Supply Chain Availability: Current inventory levels show 1038 units of the 84134900 and 995 units of the SSRT-240D10. Selection may be influenced by procurement lead times and stock availability.

Switching Characteristics: The SSRT-240D10 explicitly incorporates zero-cross switching functionality, while the 84134900 specifies AC output without explicit zero-cross notation. Applications requiring zero-cross switching should prioritize the SSRT-240D10.

Export Classification: Both parts share identical ECCN (EAR99) and HTSUS (8536.41.0060) classifications, indicating equivalent export control and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the 84134900 directly replace the SSRT-240D10 in existing designs?

A: Yes. Both parts meet identical electrical specifications (10 A at 24 V to 280 V load, 3 V to 32 VDC input) and share the same physical form factor (hockey puck chassis mount with screw terminals). Direct substitution is mechanically and electrically compatible.

Q: What is the difference between the zero-cross switching noted in the SSRT-240D10 and the standard AC output of the 84134900?

A: The SSRT-240D10 explicitly specifies zero-cross switching, which synchronizes relay activation to the AC waveform zero-crossing point to minimize electrical noise and switching transients. The 84134900 specifies AC output without explicit zero-cross notation. Applications requiring zero-cross functionality should use the SSRT-240D10.

Q: Are there RoHS compliance differences between these parts?

A: Yes. The SSRT-240D10 is RoHS non-compliant, while the 84134900 is ROHS3 compliant. Applications subject to RoHS3 regulatory requirements must use the 84134900.

Q: Do both parts have the same termination interface?

A: Yes. Both the SSRT-240D10 and 84134900 use screw terminal termination, ensuring identical PCB or panel mounting interfaces.

Q: Are the moisture sensitivity levels equivalent?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: What export control classifications apply to these parts?

A: Both parts are classified under ECCN EAR99 and HTSUS 8536.41.0060, indicating identical export control and tariff treatment.
