Engineering Selection Recommendations

DR2260A20V is the MFR-recommended substitute from Sensata Technologies. This part maintains all critical electrical parameters and is currently in Active production status. The DR2260A20V features an integrated heat sink package, which provides enhanced thermal management compared to the standard module form factor. Input voltage range extends to 90VAC/DC, offering broader input compatibility. ROHS3 compliance and REACH Affected status reflect current regulatory requirements.

GNR20ACZH is a direct manufacturer equivalent from Crouzet, maintaining the GNR series designation. This part is in Active production status and offers identical electrical specifications to the GNR20ACZ with a maximum load voltage of 660V (60V higher than the original). Mounting flexibility includes both Chassis Mount and DIN Rail options. RoHS compliance and REACH Unaffected status are documented.

Both substitute parts satisfy the functional requirements of the GNR20ACZ and are suitable for direct replacement in applications requiring SPST-NO 20A solid-state relay modules with 48-600V+ output capability and zero-cross AC switching.

Frequently Asked Questions (FAQ)

Q: Can DR2260A20V replace GNR20ACZ in all applications? A: DR2260A20V is functionally equivalent for applications requiring SPST-NO 20A AC switching at 48-600V output. The integrated heat sink provides improved thermal performance. Input voltage range extends to 90VAC/DC, making it suitable for broader input conditions. Physical package differences (integrated heat sink vs. standard module) must be verified for mechanical fit in the installation space.

Q: What is the difference between GNR20ACZH and GNR20ACZ? A: GNR20ACZH maintains identical electrical specifications and series designation. The primary differences are Active production status (vs. Last Time Buy), maximum load voltage of 660V (vs. 600V), and dual mounting capability (Chassis Mount and DIN Rail vs. DIN Rail only). Both use screw terminal connections and are RoHS compliant.

Q: Are there input voltage compatibility differences between substitutes? A: GNR20ACZ and GNR20ACZH both require 180-280VAC input. DR2260A20V accepts 90-280VAC/DC input, providing broader input voltage compatibility. Applications operating at input voltages below 180VAC require DR2260A20V.

Q: What packaging differences exist among these parts? A: GNR20ACZ and GNR20ACZH are supplied as standard modules. DR2260A20V features an integrated heat sink package. Packaging format affects thermal dissipation characteristics and physical installation requirements. Verify mechanical fit before substitution.

Q: Are all substitute parts RoHS compliant? A: Yes. GNR20ACZ and GNR20ACZH are RoHS Compliant. DR2260A20V is ROHS3 Compliant, reflecting current regulatory standards. All parts meet RoHS requirements for new designs and applications.
