P2600ECMC Equivalent & Substitute Parts

Part Overview

The P2600ECMC is a 220V off-state Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is designed for overvoltage protection applications requiring 400A peak pulse current capability in a TO-226-2 package configuration. The P2600ECMC is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P2600ECMC is determined by strict equivalence across the following critical electrical and mechanical 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
• Capacitance: 45pF
• Number of Elements: 1

The P2600ECMCL qualifies as a direct substitute based on complete electrical parameter equivalence and identical mechanical packaging specifications.

Parameter Comparison

Engineering Selection Recommendations

The P2600ECMCL is the qualified substitute for the obsolete P2600ECMC. Both components maintain identical electrical performance specifications and mechanical packaging requirements. The primary distinction is product status and regulatory compliance: the P2600ECMCL is currently in active production status and meets ROHS3 compliance requirements, whereas the P2600ECMC is obsolete and RoHS non-compliant. For new designs and ongoing system support, the P2600ECMCL is the appropriate selection. Existing systems using the P2600ECMC may continue operation with the P2600ECMCL without circuit modification, provided that RoHS compliance requirements for the end application are satisfied.

Frequently Asked Questions (FAQ)

Q: Can the P2600ECMCL directly replace the P2600ECMC in existing circuits?

A: Yes. The P2600ECMCL provides complete electrical and mechanical equivalence to the P2600ECMC. No circuit modifications are required for substitution.

Q: What is the primary reason for substituting the P2600ECMC?

A: The P2600ECMC is classified as obsolete. The P2600ECMCL is the active production equivalent, ensuring long-term component availability and supply chain continuity.

Q: Are there packaging differences between these parts?

A: No. Both the P2600ECMC and P2600ECMCL use identical TO-226-2 and TO-92-2 (TO-226AC) package configurations with through-hole mounting.

Q: What is the difference in RoHS compliance between these parts?

A: The P2600ECMC is RoHS non-compliant. The P2600ECMCL is ROHS3 compliant. For applications subject to RoHS regulations, the P2600ECMCL is the required selection.

Q: Are the electrical specifications identical?

A: Yes. Both parts maintain identical voltage ratings (220V off-state, 300V breakover, 4V on-state), peak pulse current ratings (400A at 8/20µs, 100A at 10/1000µs), hold current (150mA), and capacitance (45pF).
