Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GNR45BCZ are qualified based on the following electrical and mechanical parameters:

• Circuit configuration must be SPST-NO (1 Form A)
• Load current rating must be 45 A
• Output voltage range must encompass 48 V – 600 V
• Output type must be AC with zero-cross switching
• Mounting type must be DIN Rail
• Termination style must be Screw Terminal
• RoHS compliance status must be maintained

The substitute parts DR4560A45 and DR4560A45P meet these criteria. Both are manufactured by Sensata-Crydom and maintain electrical equivalence with the GNR45BCZ while offering extended input voltage range capability (90–280VAC/DC versus 90–140VAC). Both substitutes are in Active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

Both DR4560A45 and DR4560A45P are direct electrical equivalents to the GNR45BCZ and are suitable for replacement applications. Selection between the two substitute parts should be based on the following factors:

DR4560A45: Recommended for applications where standard DIN Rail mounting with integrated heat sink is acceptable and input voltage range of 90–280VAC/DC provides operational flexibility beyond the original GNR45BCZ specification.

DR4560A45P: Recommended for applications requiring identical functional performance with the added benefit of extended input voltage range (90–280VAC/DC). This variant maintains Active product status with full manufacturer support.

Both substitutes are RoHS Compliant and carry ECCN EAR99 classification, maintaining regulatory compliance equivalent to the original part. The integrated heat sink design in both substitute parts provides thermal management benefits compared to the standard module package of the GNR45BCZ.

Frequently Asked Questions (FAQ)

Q: Can DR4560A45 or DR4560A45P be used as direct replacements for GNR45BCZ?

A: Yes. Both substitute parts maintain identical circuit configuration (SPST-NO), load current rating (45 A), output voltage range (48–600 V), output type (AC, Zero Cross), mounting type (DIN Rail), and termination style (Screw Terminal). The substitutes are electrically equivalent and mechanically compatible.

Q: What is the difference between DR4560A45 and DR4560A45P?

A: Both parts are electrically and mechanically identical. The primary difference is the Moisture Sensitivity Level designation: DR4560A45 is rated MSL 1 (Unlimited), while DR4560A45P is listed as Not Applicable. Both are suitable for equivalent substitution.

Q: Does the extended input voltage range (90–280VAC/DC) of the substitute parts affect compatibility?

A: No. The extended input voltage range of the substitute parts is a superset of the original GNR45BCZ specification (90–140VAC). Applications operating within the original 90–140VAC range will function identically with the substitute parts.

Q: Are there package differences between GNR45BCZ and the substitute parts?

A: Yes. The GNR45BCZ is packaged as a standard Module, while DR4560A45 and DR4560A45P feature an integrated heat sink design. The integrated heat sink provides improved thermal dissipation without affecting electrical performance or DIN Rail mounting compatibility.

Q: What is the availability status of the substitute parts?

A: Both DR4560A45 and DR4560A45P are in Active product status with current inventory availability, ensuring long-term supply continuity compared to the Last Time Buy status of the GNR45BCZ.
