Equivalent & Substitute Parts for P6002AB

Part Overview

The P6002AB is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc., designed for overvoltage protection in electronic circuits. This device features dual-element protection with 275V/550V off-state voltage ratings and 250A peak pulse current capability in a 3-SIP through-hole package. The P6002AB is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P6002AB is determined by the following critical parameters:

Direct Electrical Compatibility (Same Voltage & Current Ratings):

• Voltage - Off State: 275V, 550V
• Voltage - Breakover: 350V, 700V
• Current - Peak Pulse (8/20µs): 250A
• Current - Hold (Ih): 150mA
• Number of Elements: 2
• Mounting Type: Through Hole
• Package / Case: 3-SIP

Functional Compatibility (Different Voltage/Current Ratings):

• Voltage - Off State: 140V (lower voltage application)
• Current - Peak Pulse (8/20µs): 400A (higher current capability)
• Current - Hold (Ih): 150mA (matching hold current)
• Mounting Type: Surface Mount (different form factor)
• Package / Case: DO-214AA, SMB (different package)

The P6002ABL represents a direct equivalent with identical electrical specifications and through-hole mounting, differing only in packaging format and compliance status. The SMP100LC-140 provides functional substitution for applications with lower voltage requirements and higher current capacity, but requires circuit board redesign due to surface-mount packaging.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Through-Hole, High-Voltage Applications):

The P6002ABL is the primary substitute for the obsolete P6002AB. Both components share identical electrical specifications, dual-element configuration, and through-hole mounting in the 3-SIP package. The P6002ABL is currently in active production status with ROHS3 compliance, making it suitable for new designs and legacy system maintenance where the original voltage ratings (275V/550V off-state) are required.

For Functional Substitution (Lower-Voltage, Higher-Current Applications):

The SMP100LC-140 provides an alternative for applications with reduced voltage requirements (140V off-state) and increased current handling capability (400A peak pulse). This component requires circuit board redesign due to surface-mount packaging (DO-214AA, SMB) versus the through-hole configuration of the P6002AB. The SMP100LC-140 is ROHS3 compliant and actively produced by STMicroelectronics.

Compliance Considerations:

The P6002AB is RoHS non-compliant. Both substitute options (P6002ABL and SMP100LC-140) meet ROHS3 compliance requirements, supporting modern manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the P6002ABL be used as a direct replacement for the P6002AB?

A: Yes. The P6002ABL is electrically and mechanically identical to the P6002AB, with matching voltage ratings (275V/550V off-state), current specifications (250A peak pulse), dual-element configuration, and 3-SIP through-hole package. The primary differences are product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What are the limitations of using the SMP100LC-140 as a substitute?

A: The SMP100LC-140 has lower voltage ratings (140V off-state vs. 275V/550V) and operates as a single-element device rather than dual-element. It requires surface-mount assembly (DO-214AA, SMB package) instead of through-hole mounting, necessitating circuit board redesign. Use this substitute only for applications with voltage requirements at or below 140V.

Q: Are there packaging considerations when substituting the P6002AB?

A: Yes. The P6002AB and P6002ABL both use 3-SIP through-hole packages compatible with existing PCB layouts. The SMP100LC-140 uses a surface-mount DO-214AA (SMB) package, requiring different PCB footprints and assembly processes.

Q: What is the hold current specification, and does it affect substitution?

A: The hold current (Ih) is specified at 150mA for all three components. This parameter determines the minimum current required to maintain the thyristor in the on-state and is consistent across direct and functional substitutes.

Q: How do the capacitance values differ between substitutes?

A: The P6002AB and P6002ABL both specify dual capacitance values (45pF, 80pF) reflecting their two-element configuration. The SMP100LC-140 specifies a single capacitance value of 65pF corresponding to its single-element design.
