P1602AC Equivalent & Substitute Parts

Part Overview

The P1602AC is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. as part of the SIDACtor® series. This component is designed for overvoltage protection applications requiring 65V/130V off-state voltage ratings with 400A peak pulse current capability in a 3-SIP through-hole package. The P1602AC is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the P1602AC is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute, P1602ACL, maintains identical specifications for voltage ratings (breakover, off-state, and on-state), current handling (peak pulse at both 8/20µs and 10/1000µs intervals, and hold current), element count, capacitance values, and physical packaging. Both parts utilize the same 3-SIP through-hole configuration with TO-220 Modified supplier packaging.

The substitution is valid based on the following key parameters:

• Voltage - Breakover: 95V, 190V
• Voltage - Off State: 65V, 130V
• Voltage - On State: 4 V
• Current - Peak Pulse (8/20µs): 400 A
• Current - Peak Pulse (10/1000µs): 100 A
• Current - Hold (Ih): 150 mA
• Number of Elements: 2
• Capacitance: 85pF, 145pF
• Package / Case: 3-SIP
• Mounting Type: Through Hole

Engineering Selection Recommendations

The P1602ACL is the direct equivalent substitute for the obsolete P1602AC. Both components are manufactured by Littelfuse Inc. and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status and regulatory compliance: the P1602AC is obsolete, while the P1602ACL is active and ROHS3 compliant, making it the appropriate selection for new designs and ongoing system support where RoHS compliance is required.

For applications where RoHS compliance is not a constraint, either part may be used interchangeably based on availability. However, the P1602ACL is recommended as the preferred choice due to its active product status and superior regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can P1602ACL be used as a direct replacement for P1602AC? A: Yes. The P1602ACL is electrically and mechanically identical to the P1602AC across all specified parameters, including voltage ratings, current handling, element count, capacitance, and physical packaging. The components are pin-compatible and functionally equivalent.

Q: What is the difference between P1602AC and P1602ACL? A: The primary differences are product status and regulatory compliance. The P1602AC is obsolete and RoHS non-compliant, while the P1602ACL is an active product with ROHS3 compliance. All electrical and mechanical specifications are identical.

Q: Are there any package or mounting differences? A: No. Both parts use the same 3-SIP through-hole package with TO-220 Modified supplier packaging. They are mechanically interchangeable on PCBs designed for either component.

Q: What does the "L" designation in P1602ACL indicate? A: The "L" suffix typically indicates a variant with updated compliance or packaging specifications. In this case, it denotes the active, ROHS3-compliant version of the P1602AC.

Q: Is the P1602ACL suitable for new designs? A: Yes. The P1602ACL is the recommended choice for new designs requiring a 65V/130V off-state TVS thyristor with 400A peak pulse current capability. Its active product status and RoHS compliance make it the appropriate selection for current manufacturing standards.
