Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1500ECRP1 is determined by electrical and mechanical parameter equivalence within the SIDACtor® TVS thyristor product line. The critical parameters governing substitutability are:

• Voltage ratings (breakover, off-state, and on-state)
• Peak pulse current handling (8/20µs and 10/1000µs waveforms)
• Hold current specification
• Package configuration and mounting type
• Capacitance characteristics

The P1500ECLRP1 meets all electrical specifications identically to the P1500ECRP1 and maintains the same physical package footprint, making it a direct functional equivalent. Both parts share the same base product number (P1500) and series designation, confirming compatibility at the component level.

Parameter Comparison

Engineering Selection Recommendations

The P1500ECLRP1 is the direct substitute for the obsolete P1500ECRP1. Both components are electrically and mechanically identical across all specified parameters. The P1500ECLRP1 offers the additional advantage of active product status and ROHS3 compliance, making it suitable for new designs and applications requiring regulatory adherence. Current inventory availability (914 pcs) supports production requirements. Selection of the P1500ECLRP1 eliminates obsolescence risk while maintaining full electrical compatibility with existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the P1500ECLRP1 be used as a direct replacement for the P1500ECRP1?

A: Yes. The P1500ECLRP1 is electrically and mechanically equivalent to the P1500ECRP1 across all specified parameters, including voltage ratings, current handling, and package configuration.

Q: What is the difference between these two parts?

A: The primary differences are product status and regulatory compliance. The P1500ECRP1 is obsolete and RoHS non-compliant, while the P1500ECLRP1 is active and ROHS3 compliant.

Q: Are there any package or pinout differences?

A: No. Both parts use the TO-226-2 package with identical through-hole mounting configuration and pin assignments.

Q: Does the P1500ECLRP1 require any circuit modifications?

A: No circuit modifications are required. The P1500ECLRP1 is a direct functional equivalent with identical electrical characteristics.

Q: Is the P1500ECLRP1 suitable for new designs?

A: Yes. The active product status and ROHS3 compliance make the P1500ECLRP1 appropriate for new product development and applications requiring regulatory compliance.
