P2600ECMCAP Equivalent & Substitute Parts

Part Overview

The P2600ECMCAP is a 220V off-state TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series, designed for transient voltage suppression applications. This component features a TO-226-2 package with 400A peak pulse current capability and is classified as obsolete. Due to its obsolete status, identifying functionally equivalent active alternatives is essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2600ECMCAP is determined by electrical and mechanical parameter equivalence. The primary substitution criteria are:

• Voltage ratings: Off-state voltage of 220V, breakover voltage of 300V, and on-state voltage of 4V
• Current specifications: Peak pulse current of 400A (8/20µs) and 100A (10/1000µs), with hold current of 150mA
• Capacitance: 45pF
• Package compatibility: TO-226-2 / TO-92-2 form factor with through-hole mounting
• Single-element configuration

The P2600ECMCLAP meets all these electrical and mechanical requirements, making it a direct functional equivalent for the obsolete P2600ECMCAP.

Parameter Comparison

Engineering Selection Recommendations

The P2600ECMCLAP is the direct substitute for the obsolete P2600ECMCAP. Both components share identical electrical specifications and package configurations. The P2600ECMCLAP offers the additional advantage of active product status, ensuring long-term availability and supply chain continuity. The P2600ECMCLAP is ROHS3 compliant, whereas the P2600ECMCAP is non-compliant, making the substitute the preferred choice for applications subject to RoHS requirements. The Tape & Box packaging of the P2600ECMCLAP supports automated assembly processes where applicable.

Frequently Asked Questions (FAQ)

Q: Can the P2600ECMCLAP directly replace the P2600ECMCAP in existing designs?

A: Yes. Both components have identical electrical parameters (220V off-state, 300V breakover, 400A peak pulse current) and the same TO-226-2 / TO-92-2 package configuration. No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The P2600ECMCAP is obsolete, while the P2600ECMCLAP is active. The P2600ECMCLAP is ROHS3 compliant, whereas the P2600ECMCAP is not. Packaging differs: P2600ECMCAP is supplied in bulk, while P2600ECMCLAP is supplied in Tape & Box format.

Q: Are there any compatibility concerns with the TO-226-2 package?

A: No. Both parts use the same TO-226-2 / TO-92-2 (TO-226AC) formed-lead package with through-hole mounting. PCB footprints and lead spacing are identical.

Q: Does the P2600ECMCLAP meet modern compliance standards?

A: Yes. The P2600ECMCLAP is ROHS3 compliant and REACH unaffected, making it suitable for applications with regulatory compliance requirements.

Q: What is the capacitance specification, and does it affect substitution?

A: Both parts have 45pF capacitance. This parameter is identical and does not affect substitution eligibility.
