P2600ECMCL Equivalent & Substitute Parts

Part Overview

The P2600ECMCL is a 220V off-state thyristor transient voltage suppressor (TVS) manufactured by Littelfuse, part of the SIDACtor® series. This component is designed for overvoltage protection applications requiring high peak pulse current handling. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2600ECMCL is determined by equivalence in the following critical parameters:

• Voltage - Off State: 220V
• Voltage - Breakover: 300V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 400A
• Current - Peak Pulse (10/1000µs): 100A
• Current - Hold (Ih): 150mA
• Package / Case: TO-226-2, TO-92-2 (TO-226AC)
• Mounting Type: Through Hole
• Number of Elements: 1

The P2600ECL meets all these criteria and is classified as a direct substitute. Both parts share identical electrical specifications for voltage and current ratings, the same package configuration, and equivalent mechanical mounting characteristics. Variations in secondary parameters such as capacitance do not affect substitution eligibility within the defined scope of this product category.

Parameter Comparison

Engineering Selection Recommendations

Both P2600ECMCL and P2600ECL are active production parts manufactured by Littelfuse with identical RoHS3 compliance and REACH unaffected status. Selection between these parts is based on application requirements and inventory availability. The P2600ECL offers higher capacitance (80pF versus 45pF), which may be advantageous in applications requiring increased transient energy absorption. Both parts maintain equivalent electrical performance across all voltage and current specifications. Component selection should be based on specific circuit requirements and design parameters rather than availability alone.

Frequently Asked Questions (FAQ)

Q: Can P2600ECL be used as a direct replacement for P2600ECMCL?

A: Yes. Both parts share identical voltage ratings (220V off-state, 300V breakover, 4V on-state), current specifications (400A peak pulse at 8/20µs, 100A at 10/1000µs, 150mA hold current), package configuration (TO-226-2, TO-92-2), and mounting type (through hole). The capacitance difference (80pF versus 45pF) does not prevent substitution within the defined electrical and mechanical parameters.

Q: What is the significance of the capacitance difference between these parts?

A: Capacitance values of 45pF and 80pF represent secondary electrical characteristics. Both values fall within acceptable ranges for SIDACtor® thyristor devices in this voltage and current class. The selection between these capacitance values depends on specific circuit design requirements and transient response characteristics needed for the application.

Q: Are both parts available in the same package configuration?

A: Yes. Both P2600ECMCL and P2600ECL are supplied in TO-226-2 and TO-92-2 (TO-226AC) packages with through-hole mounting. No PCB layout modifications are required when substituting between these parts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS3 compliant, REACH unaffected, and carry MSL rating of 1 (unlimited). They share identical regulatory and environmental compliance status.

Q: What factors should determine which part to select?

A: Selection should be based on circuit design requirements, capacitance specifications needed for transient response, and component availability. Both parts are functionally equivalent for overvoltage protection applications within the specified electrical parameters.
