CR2600SC Equivalent & Substitute Parts

Part Overview

The CR2600SC is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc., designed for 220V off-state voltage applications with a peak pulse current rating of 250A in the DO-214AA surface mount package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement.

TVS thyristors in this category are used for transient overvoltage protection in power distribution and industrial control circuits. The obsolete status of the CR2600SC necessitates evaluation of active alternative components that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CR2600SC is determined by the following critical parameters:

• Voltage Rating Match: Off-state voltage of 220V and breakover voltage of 300V must be maintained
• Package Compatibility: DO-214AA, SMB surface mount package required for PCB footprint compatibility
• Current Handling: Peak pulse current capability must meet or exceed the application requirement
• Electrical Characteristics: On-state voltage, hold current, and capacitance must fall within acceptable operating ranges

The P2600SCLRP meets these substitution criteria while offering enhanced current capability and active product status.

Parameter Comparison

Engineering Selection Recommendations

The P2600SCLRP is the direct substitute for the CR2600SC based on the following factors:

• Product Status: The P2600SCLRP maintains active product status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: ROHS3 compliance of the P2600SCLRP addresses environmental and regulatory requirements not met by the obsolete CR2600SC
• Electrical Compatibility: Identical voltage ratings (300V breakover, 220V off-state) and hold current (150mA) ensure functional equivalence
• Enhanced Performance: The 400A peak pulse current rating of the P2600SCLRP exceeds the 250A requirement of the CR2600SC, providing design margin
• Package Equivalence: Both components use the DO-214AA, SMB surface mount package, enabling direct PCB footprint compatibility
• Series Designation: The P2600SCLRP belongs to the SIDACtor® series, representing the current generation of this component family

Frequently Asked Questions (FAQ)

Q: Can the P2600SCLRP be used as a direct replacement for the CR2600SC?

A: Yes. Both components share identical voltage ratings (300V breakover, 220V off-state), hold current (150mA), and package configuration (DO-214AA, SMB). The P2600SCLRP provides equivalent or superior electrical performance with active product status.

Q: What are the differences between the CR2600SC and P2600SCLRP?

A: The P2600SCLRP offers 400A peak pulse current (8/20µs) compared to the CR2600SC's 250A, a lower on-state voltage (4V vs. 5V), and higher capacitance (80pF vs. 60pF). The P2600SCLRP is ROHS3 compliant and maintains active product status.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both components use the identical DO-214AA, SMB package, requiring no PCB layout modifications. Existing footprints and assembly processes remain unchanged.

Q: Does the higher current rating of the P2600SCLRP affect circuit operation?

A: No. The higher peak pulse current rating of the P2600SCLRP (400A vs. 250A) represents increased capability without affecting normal circuit operation. This provides additional design margin for transient protection.

Q: What is the significance of ROHS3 compliance?

A: ROHS3 compliance indicates the P2600SCLRP meets current environmental and hazardous substance restrictions, making it suitable for applications subject to regulatory compliance requirements that the non-compliant CR2600SC does not satisfy.
