Substitute Part Grouping Explanation

Substitution for the D53DP50D is determined by strict equivalence across the following critical parameters:

• Circuit configuration: 3PST-NO (3 Form A) topology
• Load current rating: 50 A minimum
• Load voltage range: 48 V ~ 530 V
• Input control voltage: 4 ~ 32VDC
• Output switching type: AC with zero-cross capability
• Termination: Screw terminal connection
• Mounting: Chassis mount module form factor

The D53TP50D qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all critical parameters. The primary distinction is product status: D53TP50D is active production, whereas D53DP50D is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The D53TP50D is the direct equivalent for D53DP50D applications. Selection is based on the following factors:

Electrical equivalence is complete across input control voltage, load voltage range, current capacity, and switching characteristics. Both parts operate identically within the specified parameter ranges.

D53TP50D is in active production status, ensuring availability and supply chain continuity. D53DP50D obsolescence necessitates transition to an active equivalent.

D53TP50D carries ROHS3 compliance certification, meeting current environmental and regulatory standards. This represents an improvement over the original part specification.

Mechanical and electrical interfaces are identical, permitting direct substitution without circuit redesign or mechanical modification.

Frequently Asked Questions (FAQ)

Q: Can D53TP50D replace D53DP50D in existing applications?

A: Yes. D53TP50D is electrically and mechanically equivalent to D53DP50D. All critical parameters—circuit configuration, voltage ratings, current capacity, input control range, and termination style—are identical. Direct substitution is possible without modification.

Q: What is the primary reason for substitution?

A: D53DP50D is obsolete. D53TP50D is the active production equivalent from the same manufacturer and series, ensuring continued availability and supply chain support.

Q: Are there differences in compliance or certification?

A: D53TP50D carries ROHS3 compliance certification. D53DP50D compliance status is not specified. Both parts share identical ECCN and HTSUS classifications. REACH status differs: D53DP50D is REACH Unaffected; D53TP50D is REACH Affected.
