P4202ACMCL Equivalent & Substitute Parts

Part Overview

The P4202ACMCL is an active-status Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. under the SIDACtor® series. This component provides transient overvoltage protection in 3-SIP through-hole configuration with dual-element architecture. The part is specified for 190V/380V off-state voltage operation with 400A peak pulse current capability (8/20µs). Substitute parts are identified to support procurement continuity and inventory optimization while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P4202ACMCL is determined by strict equivalence across the following critical parameters:

• Voltage ratings: Off-state voltage (190V, 380V), breakover voltage (250V, 500V), and on-state voltage (4V) must match exactly
• Current specifications: Peak pulse current (8/20µs: 400A; 10/1000µs: 100A) and hold current (150mA) must be identical
• Electrical architecture: Dual-element configuration (2 elements) required
• Package and mounting: 3-SIP through-hole package with TO-220 Modified supplier device package
• Compliance: ROHS3 compliance and MSL 1 rating maintained

The P4202ACL meets all substitution criteria and is classified as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

Both P4202ACMCL and P4202ACL are active-status components manufactured by Littelfuse Inc. under identical electrical and mechanical specifications. Selection between these parts is based on inventory availability and procurement lead time:

• P4202ACMCL: 945 units in stock
• P4202ACL: 2200 units in stock

Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating. No electrical or mechanical differentiation exists between these parts for circuit design purposes. The P4202ACL offers superior inventory availability for high-volume procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can P4202ACL be used as a direct replacement for P4202ACMCL in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including voltage ratings, current ratings, element count, and package configuration. No circuit redesign or PCB modification is required.

Q: What is the difference between P4202ACMCL and P4202ACL?

A: The parts differ only in capacitance specification (P4202ACMCL: 30pF, 50pF; P4202ACL: 50pF, 85pF) and inventory quantity. All other electrical and mechanical parameters are identical. Capacitance variation does not affect substitution eligibility for TVS thyristor applications where transient suppression is the primary function.

Q: Are both parts suitable for through-hole PCB assembly?

A: Yes. Both P4202ACMCL and P4202ACL are specified for through-hole mounting in 3-SIP package configuration with TO-220 Modified supplier device package. Standard through-hole assembly processes apply.

Q: Do both parts meet regulatory compliance requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. No additional compliance documentation is required for substitution.

Q: What is the minimum hold current for these TVS thyristors?

A: The hold current (Ih) is specified at 150 mA for both P4202ACMCL and P4202ACL. This parameter determines the minimum current required to maintain the thyristor in the on-state after triggering.
