P0640ECAP Equivalent & Substitute Parts

Part Overview

The P0640ECAP is a 58V off-state TVS thyristor manufactured by Littelfuse Inc., classified as a Transient Voltage Suppressor (TVS) device in the SIDACtor® series. This component is designed for transient voltage protection applications requiring 400A peak pulse current capability in a TO-226-2 package configuration. The P0640ECAP is currently listed as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure supply chain availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0640ECAP is determined by electrical and mechanical parameter equivalence. The primary substitute, P0640ECLAP, maintains identical electrical specifications across all critical parameters: 58V off-state voltage, 77V breakover voltage, 4V on-state voltage, 400A peak pulse current (8/20µs), 100A peak pulse current (10/1000µs), 150mA hold current, and 155pF capacitance. Both parts share the same base product number (P0640), package configuration (TO-226-2, TO-92-2), and mounting type (Through Hole).

The key parameters determining substitution eligibility are:

• Voltage ratings (off-state, breakover, on-state)
• Peak pulse current capabilities (8/20µs and 10/1000µs)
• Hold current specification
• Package and mounting compatibility

Parameter Comparison

Engineering Selection Recommendations

The P0640ECLAP is the direct functional equivalent of the P0640ECAP. Both components are manufactured by Littelfuse Inc. within the SIDACtor® series and share identical electrical and mechanical specifications. The P0640ECLAP is currently in active production status, whereas the P0640ECAP is obsolete.

The P0640ECLAP provides additional compliance advantages: it meets ROHS3 requirements and is REACH unaffected, compared to the P0640ECAP which is RoHS non-compliant. For applications requiring compliance with current environmental regulations, the P0640ECLAP is the appropriate selection. The P0640ECLAP is supplied in Tape & Box (TB) packaging, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can P0640ECLAP directly replace P0640ECAP in existing designs?

A: Yes. The P0640ECLAP provides identical electrical performance across all specified parameters: voltage ratings, peak pulse currents, hold current, and capacitance. Both components use the same TO-226-2 package and through-hole mounting configuration, enabling direct substitution without circuit modification.

Q: What is the difference between P0640ECAP and P0640ECLAP?

A: The primary differences are product status and compliance certifications. The P0640ECAP is obsolete and RoHS non-compliant. The P0640ECLAP is active production and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The P0640ECLAP is supplied in Tape & Box (TB) packaging. The P0640ECAP packaging specification was not provided. Both parts use the same TO-226-2, TO-92-2 (TO-226AC) package case with formed leads and through-hole mounting.

Q: Which part should be selected for new designs?

A: The P0640ECLAP should be selected for new designs. It is in active production status and meets current RoHS3 compliance requirements, ensuring long-term supply availability and regulatory compliance.

Q: Are there any thermal or performance differences?

A: No thermal or performance differences exist between these parts. All electrical specifications, including peak pulse current handling, on-state voltage, and hold current, are identical.
