P0640ECMCAP Equivalent & Substitute Parts

Part Overview

The P0640ECMCAP is a 58V off-state TVS thyristor from Littelfuse Inc., part of the SIDACtor® series, designed for transient voltage suppression applications. This component features a TO-226-2 package with through-hole mounting and is rated for 400 A peak pulse current (8/20µs). The P0640ECMCAP 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 P0640ECMCAP is determined by electrical and mechanical parameter equivalence within the TVS thyristor category. The critical parameters governing substitution are:

• Voltage - Off State: 58V
• Voltage - Breakover: 77V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 400A
• Current - Peak Pulse (10/1000µs): 100A
• Current - Hold (Ih): 150mA
• Capacitance: 85pF
• Package / Case: TO-226-2, TO-92-2 (TO-226AC)
• Mounting Type: Through Hole

The P0640ECMCLAP meets all electrical specifications and mechanical requirements, differing only in product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The P0640ECMCLAP is the direct substitute for the P0640ECMCAP. Both components share identical electrical specifications and mechanical package configurations. The P0640ECMCLAP is currently in active production status, whereas the P0640ECMCAP is obsolete. The P0640ECMCLAP carries ROHS3 compliance certification, meeting current regulatory requirements for electronic component manufacturing and distribution. The packaging difference (Tape & Box versus bulk) does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can P0640ECMCLAP directly replace P0640ECMCAP in existing designs?

A: Yes. The P0640ECMCLAP is electrically and mechanically equivalent to the P0640ECMCAP across all specified parameters, including voltage ratings, current ratings, capacitance, and package configuration.

Q: What is the difference between the two part numbers?

A: The primary differences are product status (obsolete versus active), packaging format (bulk versus Tape & Box), and RoHS compliance certification (non-compliant versus ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Does the Tape & Box packaging affect circuit board assembly?

A: No. The Tape & Box packaging is a distribution format that does not alter the component's physical dimensions, lead configuration, or electrical characteristics. The component itself remains in the TO-226-2 package with through-hole mounting.

Q: Is the P0640ECMCLAP suitable for new designs?

A: Yes. The P0640ECMCLAP is in active production status and carries current regulatory compliance certifications, making it appropriate for new product development.

Q: Are there any electrical performance differences between these parts?

A: No. Both components are rated for identical off-state voltage (58V), breakover voltage (77V), on-state voltage (4V), peak pulse current (400A at 8/20µs), hold current (150mA), and capacitance (85pF).
