P1300ECMCAP Equivalent & Substitute Parts

Part Overview

The P1300ECMCAP is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse, part of the SIDACtor® series. This component is designed for overvoltage protection applications, featuring a 120V off-state voltage rating and 400A peak pulse current capability in a TO-226-2 package with formed leads. The P1300ECMCAP is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1300ECMCAP is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage ratings: Breakover voltage (160V), off-state voltage (120V), and on-state voltage (4V) must match exactly
• Current specifications: Peak pulse current at 8/20µs (400A) and 10/1000µs (100A) must be identical
• Hold current (Ih): 150mA requirement must be maintained
• Capacitance: 60pF specification must be preserved
• Package compatibility: TO-226-2 or TO-92-2 (TO-226AC) formed leads configuration
• Single element configuration: Number of elements must remain 1

The P1300ECMCLAP meets all these criteria and qualifies as a direct substitute for the obsolete P1300ECMCAP.

Parameter Comparison

Engineering Selection Recommendations

The P1300ECMCLAP is the qualified substitute for the obsolete P1300ECMCAP. Both components maintain identical electrical specifications and package configurations, ensuring direct functional equivalence in circuit applications.

The P1300ECMCLAP offers the additional advantage of active product status, ensuring continued availability and supply chain reliability. The P1300ECMCLAP achieves ROHS3 compliance, whereas the P1300ECMCAP is non-compliant. For applications subject to RoHS regulatory requirements, the P1300ECMCLAP is the appropriate selection. The P1300ECMCLAP is supplied in Tape & Box packaging, facilitating automated assembly processes where applicable.

Frequently Asked Questions (FAQ)

Q: Can the P1300ECMCLAP directly replace the P1300ECMCAP in existing designs?

A: Yes. The P1300ECMCLAP is electrically and mechanically equivalent to the P1300ECMCAP across all specified parameters, including voltage ratings, current ratings, capacitance, and package configuration. No circuit modifications are required.

Q: What is the primary reason for substitution?

A: The P1300ECMCAP is classified as obsolete. The P1300ECMCLAP is an active product from the same manufacturer and series, providing continued component availability.

Q: Are there packaging differences between these parts?

A: The P1300ECMCAP packaging is unspecified in the available data. The P1300ECMCLAP is supplied in Tape & Box (TB) packaging. Both components use the same TO-226-2 / TO-92-2 (TO-226AC) formed leads package configuration for circuit board mounting.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical characteristics. Both parts deliver identical electrical performance. The P1300ECMCLAP's ROHS3 compliance makes it suitable for applications with regulatory requirements.

Q: Are both parts from the same manufacturer?

A: Yes. Both the P1300ECMCAP and P1300ECMCLAP are manufactured by Littelfuse and belong to the SIDACtor® series.
