D53TP50C Solid State Relay - Equivalent & Substitute Parts

Part Overview

The D53TP50C is an active, ROHS3 compliant solid state relay manufactured by Sensata-Crydom. This 3PST-NO (3 Form A) module operates with DC input control (4-32VDC) and AC output switching at 50A load current across 48-530V. The device features zero-cross switching capability and screw terminal connections in a chassis-mount module package. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D53TP50C is determined by the following criteria:

Required Matching Parameters:

• Circuit configuration: 3PST-NO (3 Form A)
• Output type: AC, Zero Cross
• Input voltage range: 4 ~ 32VDC
• Termination style: Screw Terminal
• Package type: Module
• RoHS compliance: ROHS3 Compliant

Allowable Parameter Variations:

• Load current: Equal to or greater than 50A
• Load voltage range: Must encompass or overlap the 48-530V requirement
• Mounting type: Chassis Mount or Panel Mount acceptable
• Manufacturer: Different manufacturers permitted

The identified substitutes meet these criteria while maintaining functional equivalence for solid state relay applications requiring 3PST-NO switching with AC zero-cross output control.

Parameter Comparison

Engineering Selection Recommendations

All three solid state relay modules listed maintain active product status and ROHS3 compliance. Selection between the D53TP50C and its substitutes depends on specific application load voltage and current requirements:

D53TP50C (Sensata-Crydom): Primary choice for applications requiring minimum load voltage of 48V at 50A switching capacity.

ASR-SQF480D60ZW (Altran Magnetics): Suitable for applications operating at 24V minimum load voltage with higher current capacity (60A). Load voltage range extends to 530V, matching the upper specification of the primary part.

GN350DSZH (Crouzet): Applicable for applications requiring 24V minimum load voltage at 50A capacity. Supports both chassis and panel mounting configurations. Load voltage range extends to 510V.

All three modules feature identical input control voltage (4-32VDC), zero-cross AC output switching, and screw terminal connections. Selection should be based on the specific load voltage floor requirement of the application circuit.

Frequently Asked Questions (FAQ)

Q: Can ASR-SQF480D60ZW replace D53TP50C in all applications?

A: ASR-SQF480D60ZW is functionally equivalent for applications where the load voltage does not drop below 24V. The D53TP50C specifies a 48V minimum load voltage. If your application operates between 24-48V, ASR-SQF480D60ZW is suitable. If operation below 24V is required, neither substitute is appropriate.

Q: What is the significance of the 60A rating on ASR-SQF480D60ZW versus 50A on D53TP50C?

A: The 60A rating indicates higher current-switching capacity. This part can switch loads up to 60A, exceeding the 50A requirement of D53TP50C. This represents a capability upgrade and does not prevent substitution in 50A applications.

Q: Does GN350DSZH panel mount capability affect compatibility?

A: GN350DSZH supports both chassis and panel mounting, while D53TP50C specifies chassis mount only. This additional mounting flexibility does not compromise substitution eligibility. The part can be installed in chassis-mount applications without modification.

Q: Are there load voltage differences that affect substitution?

A: D53TP50C operates 48-530V. ASR-SQF480D60ZW operates 24-530V. GN350DSZH operates 24-510V. All three cover the 48-530V range of the primary part. If your application requires operation below 48V, only the substitute parts are suitable.

Q: Do packaging differences (Tube vs. Box) affect electrical performance?

A: Packaging format (Tube for D53TP50C, Box for substitutes) affects logistics and storage only. Electrical specifications and performance characteristics remain identical regardless of packaging format.
