D53TP50DH Solid State Relay - Equivalent & Substitute Parts

Part Overview

The D53TP50DH is an active, ROHS3 compliant solid state relay manufactured by Sensata-Crydom. This 3PST-NO (3 Form A) module operates with 4-32VDC input control and handles AC loads up to 530V at 50A capacity. The device features zero-cross switching and screw terminal connections for chassis mount applications.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when system design requires alternative mounting configurations or current ratings within compatible electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D53TP50DH is determined by the following criteria:

Required Matching Parameters:

• Circuit configuration: 3PST-NO (3 Form A)
• Input voltage range: 4 - 32VDC
• Output type: AC with zero-cross switching
• Termination style: Screw Terminal
• Package type: Module
• Mounting compatibility: Chassis mount capability

Allowable Variation Parameters:

• Load current: Equal to or greater than 50A
• Load voltage range: Must encompass or exceed 48 - 530V minimum specification
• Mounting type: May include additional mounting options (panel mount) beyond chassis mount
• Packaging format: Box or Bulk acceptable

Both identified substitutes meet these criteria while maintaining electrical and mechanical compatibility with D53TP50DH applications.

Parameter Comparison

Engineering Selection Recommendations

ASR-SQF480D60ZW-P (Altran Magnetics, LLC): This substitute provides 60A load current capacity, exceeding the D53TP50DH specification of 50A. Load voltage range extends to 530V, matching the upper limit of the original part. Input control voltage and circuit configuration remain identical. ROHS3 compliance is maintained. This part is suitable for applications requiring equal or higher current capacity within the specified voltage envelope.

GN350DSZH (Crouzet): This substitute maintains the 50A load current specification of the D53TP50DH. Load voltage range spans 24-510V, providing lower minimum voltage coverage (24V versus 48V) while maintaining compatibility at 510V. The GN350DSZH offers expanded mounting flexibility with both chassis and panel mount capability. ROHS3 compliance is confirmed. This part is suitable for applications where the lower load voltage minimum is acceptable and mounting flexibility is beneficial.

Both substitutes maintain active product status and full regulatory compliance (ROHS3, EAR99 classification).

Frequently Asked Questions (FAQ)

Q: Can ASR-SQF480D60ZW-P replace D53TP50DH in all applications? A: Yes, within electrical parameter limits. The 60A rating of ASR-SQF480D60ZW-P exceeds the 50A requirement, and the 24-530V load voltage range encompasses the original 48-530V specification. Input control voltage, circuit configuration, and switching characteristics are identical.

Q: What is the primary difference between GN350DSZH and D53TP50DH? A: The GN350DSZH supports load voltage as low as 24V (versus 48V minimum on D53TP50DH) and offers dual mounting options (chassis or panel mount). Load current and input control voltage specifications are identical. Maximum load voltage is 510V versus 530V on the original part.

Q: Are all three parts ROHS3 compliant? A: Yes. D53TP50DH, ASR-SQF480D60ZW-P, and GN350DSZH are all ROHS3 compliant.

Q: Can I use a substitute with higher current rating in a 50A application? A: Yes. ASR-SQF480D60ZW-P at 60A capacity is suitable for applications designed for 50A operation. The higher rating provides operational margin without affecting circuit performance.

Q: Does load voltage range affect substitution compatibility? A: Load voltage range must encompass the application requirement. ASR-SQF480D60ZW-P (24-530V) and GN350DSZH (24-510V) both cover the D53TP50DH range of 48-530V. If your application operates below 48V, only GN350DSZH and ASR-SQF480D60ZW-P are suitable.

Q: Are there mounting differences between these parts? A: D53TP50DH and ASR-SQF480D60ZW-P are chassis mount only. GN350DSZH supports both chassis and panel mount configurations, providing installation flexibility.
