P0720ECRP1 Equivalent & Substitute Parts

Part Overview

The P0720ECRP1 is a 65V off-state, 400A peak pulse TVS thyristor manufactured by Littelfuse in the SIDACtor® series. This component is designed for transient voltage suppression applications requiring high peak current handling in a compact TO-226-2 package. The part is currently obsolete, making identification of suitable substitutes essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0720ECRP1 is determined by electrical and mechanical parameter equivalence within the TVS thyristor category. The critical parameters governing substitution are:

• Voltage - Off State: 65V
• Voltage - Breakover: 88V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 400A
• Current - Peak Pulse (10/1000µs): 100A
• Current - Hold (Ih): 150mA
• Capacitance: 150pF
• Package / Case: TO-226-2, TO-92-2 (TO-226AC)
• Mounting Type: Through Hole

Parts meeting all these electrical and mechanical specifications are direct functional equivalents and may be substituted without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The P0720ECLRP1 is a direct electrical and mechanical equivalent to the P0720ECRP1. Both parts share identical electrical specifications across all critical parameters: off-state voltage, breakover voltage, on-state voltage, peak pulse currents, hold current, capacitance, and package configuration.

The primary distinction between these parts is product status and compliance posture. The P0720ECRP1 is obsolete and RoHS non-compliant, while the P0720ECLRP1 is active and ROHS3 compliant. For new designs or systems requiring regulatory compliance, the P0720ECLRP1 is the appropriate selection. For legacy system maintenance where the original part specification must be preserved, the P0720ECLRP1 provides functional equivalence with improved compliance status.

The packaging difference (bulk versus Tape & Reel) reflects supply chain configuration and does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the P0720ECLRP1 replace the P0720ECRP1 in existing circuits?

A: Yes. The P0720ECLRP1 is electrically and mechanically identical to the P0720ECRP1 across all specified parameters. Direct substitution is possible without circuit modification.

Q: What is the difference between the bulk and Tape & Reel packaging?

A: Packaging format affects supply chain handling and automated assembly compatibility but does not alter electrical performance or physical dimensions. Both formats contain the same component in the TO-226-2 package.

Q: Why is RoHS compliance status different between these parts?

A: The P0720ECRP1 is an obsolete part manufactured under earlier standards. The P0720ECLRP1 represents the current production equivalent with updated compliance certifications including ROHS3.

Q: Are there any thermal or reliability differences between these parts?

A: No thermal or reliability parameters are provided in the component specifications. Both parts are from the same SIDACtor® series and share identical electrical ratings.

Q: Can I use the P0720ECLRP1 in high-volume automated assembly?

A: The P0720ECLRP1 is available in Tape & Reel packaging, which is suitable for automated pick-and-place assembly. The P0720ECRP1 bulk packaging is not optimized for automated processes.
