Littelfuse P2600EC Transient Voltage Suppressor - Equivalent & Substitute Parts

Part Overview

The Littelfuse P2600EC is a 220V off-state thyristor-based transient voltage suppressor (TVS) in the SIDACtor® series, designed for surge protection applications requiring 400A peak pulse current handling. The device features a TO-226-2 package configuration and is rated for 300V breakover voltage with 4V on-state voltage.

The P2600EC is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2600EC is determined by electrical and mechanical parameter equivalence within the SIDACtor® thyristor family. The critical parameters governing substitution are:

• 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

The P2600ECL meets all electrical and mechanical specifications identical to the P2600EC, establishing it as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The P2600ECL is the direct substitute for the obsolete P2600EC. Both components are manufactured by Littelfuse and share identical electrical and mechanical specifications.

The P2600ECL offers the advantage of active product status, ensuring ongoing availability and manufacturing support. The P2600ECL is RoHS3 compliant and REACH unaffected, whereas the P2600EC is non-compliant with RoHS requirements. For new designs and production applications subject to environmental compliance mandates, the P2600ECL is the appropriate selection.

Both parts carry the same ECCN (EAR99) and HTSUS (8541.30.0080) classifications and share unlimited moisture sensitivity level (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can the P2600ECL be used as a direct replacement for the P2600EC?

A: Yes. The P2600ECL is electrically and mechanically identical to the P2600EC across all specified parameters, including voltage ratings, current ratings, capacitance, and package configuration.

Q: What is the primary difference between the P2600EC and P2600ECL?

A: The P2600EC is obsolete, while the P2600ECL maintains active product status. The P2600ECL is RoHS3 compliant; the P2600EC is not. Packaging differs: P2600EC uses tape and reel; P2600ECL uses bulk packaging.

Q: Are there any circuit design modifications required when substituting the P2600ECL for the P2600EC?

A: No. Identical electrical parameters eliminate the need for circuit modifications. Pin configuration and package footprint remain unchanged.

Q: What is the TO-226-2 package configuration?

A: TO-226-2 is a two-lead through-hole package, also designated TO-92-2 (TO-226AC). This configuration accommodates the single-element thyristor design with standard PCB mounting.

Q: Does the P2600ECL meet current environmental compliance standards?

A: Yes. The P2600ECL is RoHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components.
