P2202AC60 Equivalent & Substitute Parts

Part Overview

The P2202AC60 is a SIDACtor® thyristor transient voltage suppressor manufactured by Littelfuse Inc., designed for overvoltage protection in 90V and 180V off-state applications. This component features a 400A peak pulse current rating (8/20µs) and is housed in a 3-SIP TO-220 Modified package for through-hole mounting.

The P2202AC60 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2202AC60 is determined by strict equivalence across the following critical parameters:

• Voltage ratings (off-state, breakover, on-state) must remain identical
• Number of elements must match (2 elements required)
• Capacitance values must be identical
• Package and mounting type must be compatible (3-SIP TO-220 Modified, through-hole)
• Current ratings may vary within acceptable operational limits for the application

The P2202ABL qualifies as a substitute based on matching voltage specifications, element count, capacitance, and package configuration. The primary difference is a reduced peak pulse current rating (250A vs. 400A at 8/20µs), which represents a derating that may be acceptable depending on circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The P2202ABL is the manufacturer-recommended substitute for the P2202AC60. Selection should be based on the following factors:

Product Status: The P2202AC60 is obsolete, while the P2202ABL is active and maintains ongoing manufacturing support and availability.

Compliance: The P2202ABL achieves ROHS3 compliance and REACH unaffected status, whereas the P2202AC60 is RoHS non-compliant. For applications subject to environmental or regulatory requirements, the P2202ABL provides compliance alignment.

Current Rating Derating: The P2202ABL operates at 250A peak pulse current (8/20µs) compared to the P2202AC60 at 400A. Circuit designs must confirm that the reduced current rating remains within acceptable operational margins for the intended application.

Electrical Equivalence: Voltage specifications, element configuration, and capacitance values are identical, ensuring functional compatibility in circuits designed for the P2202AC60 electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can the P2202ABL directly replace the P2202AC60 in existing designs?

A: Electrical compatibility is confirmed across voltage ratings, breakover characteristics, on-state voltage, hold current, element count, and capacitance. The primary consideration is the reduced peak pulse current rating (250A vs. 400A). Direct replacement is feasible if circuit transient current demands do not exceed 250A at 8/20µs pulse duration.

Q: What is the significance of the current rating difference between these parts?

A: The P2202ABL is rated for 250A peak pulse current (8/20µs) and 80A peak pulse current (10/1000µs), compared to the P2202AC60 at 400A and 100A respectively. This represents a derating of the current handling capability. Applications must be evaluated to confirm that transient surge currents remain within the P2202ABL limits.

Q: Are the packages physically identical?

A: Both parts use the 3-SIP TO-220 Modified package with through-hole mounting. Physical footprint and board layout compatibility are maintained.

Q: What compliance advantages does the P2202ABL offer?

A: The P2202ABL is ROHS3 compliant and REACH unaffected, whereas the P2202AC60 is RoHS non-compliant. For applications subject to environmental directives or customer compliance requirements, the P2202ABL provides regulatory alignment.

Q: Why is the P2202AC60 listed as obsolete?

A: Obsolescence indicates that the manufacturer has discontinued production. The P2202ABL represents the active product line continuation within the SIDACtor® series for equivalent voltage and element configurations.
