P1602AC60 Equivalent & Substitute Parts

Part Overview

The P1602AC60 is a SIDACtor® thyristor transient voltage suppressor manufactured by Littelfuse Inc., designed for overvoltage protection applications requiring 65V/130V off-state voltage ratings with 400A peak pulse current capability. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The P1602AC60 operates in a 3-SIP through-hole package configuration and is RoHS non-compliant.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P1602AC60 is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage ratings (breakover and off-state): 95V/190V and 65V/130V respectively
• Peak pulse current capability: 400A at 8/20µs pulse width
• On-state voltage: 4V maximum
• Hold current: 150mA
• Element count: 2 elements
• Capacitance characteristics: 85pF and 145pF
• Package configuration: 3-SIP through-hole
• Supplier device package: TO-220 Modified

The P1602ACL60 meets all these electrical and mechanical requirements, establishing it as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The P1602ACL60 is the direct equivalent for the obsolete P1602AC60. Both components share identical electrical specifications and mechanical packaging. The P1602ACL60 offers two significant advantages: it maintains active product status with Littelfuse Inc., ensuring continued availability and technical support, and it achieves ROHS3 compliance, meeting modern regulatory requirements for electronic components. The P1602ACL60 is available in bulk packaging with 829 units in stock.

For applications currently using the P1602AC60, transition to the P1602ACL60 is supported by complete parameter equivalence and improved compliance posture.

Frequently Asked Questions (FAQ)

Q: Can the P1602ACL60 directly replace the P1602AC60 in existing designs?

A: Yes. The P1602ACL60 is electrically and mechanically identical to the P1602AC60 across all specified parameters, including voltage ratings, current ratings, capacitance, and 3-SIP through-hole package configuration. Direct substitution is supported.

Q: What is the difference between P1602AC60 and P1602ACL60?

A: The primary differences are product status and regulatory compliance. The P1602AC60 is obsolete and RoHS non-compliant, while the P1602ACL60 is active and ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Why is the P1602AC60 listed as obsolete?

A: Littelfuse Inc. has discontinued the P1602AC60 in favor of the P1602ACL60, which provides the same functionality with improved compliance and ongoing support.

Q: Are there packaging differences between these parts?

A: Both components use identical 3-SIP through-hole packaging with TO-220 Modified supplier device package configuration. The P1602ACL60 is supplied in bulk packaging, while the P1602AC60 was supplied in standard packaging.

Q: What applications use the P1602AC60 / P1602ACL60?

A: These SIDACtor® thyristor devices are used in transient voltage suppression circuits requiring dual-element protection with 65V/130V off-state voltage ratings and 400A peak pulse current handling.
