P0640ECMCL Equivalent & Substitute Parts

Part Overview

The P0640ECMCL is a 58V off-state, 400A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is designed for transient voltage suppression applications requiring high current handling capability in a compact TO-226-2 package. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints or application-specific packaging preferences.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P0640ECMCL is based on electrical parameter equivalence within the SIDACtor® series. The substitute part P0640ECL maintains identical voltage ratings (58V off-state, 77V breakover, 4V on-state), current specifications (400A peak pulse at 8/20µs, 100A at 10/1000µs, 150mA hold current), and mechanical compatibility (TO-226-2 package, through-hole mounting). Both parts share the same base product number (P0640), series designation, and compliance certifications. The primary distinction is capacitance rating, which does not affect substitution eligibility for standard transient voltage suppression applications. Both parts are active products with full RoHS3 compliance and unlimited moisture sensitivity rating.

Parameter Comparison

Engineering Selection Recommendations

Both P0640ECMCL and P0640ECL are qualified for direct substitution in transient voltage suppression circuits. Selection between these parts should be based on inventory availability and application-specific requirements. Both parts maintain active product status, full RoHS3 compliance, and REACH unaffected designation. The electrical performance is identical across all critical parameters: voltage ratings, peak pulse current, hold current, and on-state voltage. Both components are supplied in the same package configuration (TO-226-2) with through-hole mounting compatibility. Compliance certifications (ROHS3, REACH, EAR99 ECCN) are equivalent for both parts.

Frequently Asked Questions (FAQ)

Q: Can P0640ECL replace P0640ECMCL in existing designs? A: Yes. Both parts are electrically equivalent with identical voltage ratings (58V off-state, 77V breakover), current specifications (400A peak pulse), and package configuration (TO-226-2). They are direct substitutes within the SIDACtor® series.

Q: What is the difference between P0640ECMCL and P0640ECL? A: The parts differ only in capacitance rating: P0640ECMCL has 85pF capacitance while P0640ECL has 155pF. All other electrical and mechanical parameters are identical. Capacitance differences do not affect substitution eligibility for standard TVS applications.

Q: Are both parts RoHS compliant? A: Yes. Both P0640ECMCL and P0640ECL are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What package types are available for these parts? A: Both parts are supplied in TO-226-2 and TO-92-2 (TO-226AC) package configurations with through-hole mounting.

Q: Can these parts be used interchangeably in PCB designs? A: Yes. Both parts share identical package specifications and pin configurations, allowing direct PCB layout compatibility without design modifications.

Q: What is the product status of these substitute parts? A: Both P0640ECMCL and P0640ECL maintain active product status with ongoing manufacturer support and availability.
