P3602ACRP Equivalent & Substitute Parts

Part Overview

The P3602ACRP is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. as part of the SIDACtor® series. This component is designed for 170V/340V off-state voltage applications with a peak pulse current rating of 400A in an 8/20µs waveform. The P3602ACRP is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P3602ACRP is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage ratings (breakover and off-state) must match exactly: 220V/440V breakover and 170V/340V off-state
• Peak pulse current capacity must be maintained at 400A (8/20µs) and 100A (10/1000µs)
• On-state voltage must remain at 4V
• Hold current specification must be 150mA
• Package configuration must be 3-SIP with TO-220 Modified supplier device package
• Mounting type must be Through Hole
• Number of elements must be 2

The P3602ACLRP meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is packaging format and product status.

Engineering Selection Recommendations

The P3602ACLRP is the direct substitute for the P3602ACRP. Both parts are electrically and mechanically identical across all functional parameters. Selection between these parts should be based on the following factors:

Product Status: The P3602ACRP is obsolete, while the P3602ACLRP is active. For new designs and ongoing production, the P3602ACLRP is the appropriate choice.

Regulatory Compliance: The P3602ACLRP is ROHS3 compliant, whereas the P3602ACRP is RoHS non-compliant. Applications subject to RoHS regulations require the P3602ACLRP.

Packaging Format: The P3602ACRP is supplied in bulk packaging, while the P3602ACLRP is supplied in Tape & Reel format. Packaging selection depends on production volume and assembly line requirements.

Inventory Availability: The P3602ACLRP has 1133 pieces in stock compared to 939 pieces for the P3602ACRP, providing greater availability for immediate procurement.

Frequently Asked Questions (FAQ)

Q: Can the P3602ACLRP be used as a direct replacement for the P3602ACRP in existing designs?

A: Yes. The P3602ACLRP is electrically and mechanically identical to the P3602ACRP. All electrical parameters, including voltage ratings, current ratings, and on-state characteristics, are equivalent. The 3-SIP package and TO-220 Modified supplier device package are identical, allowing direct PCB substitution.

Q: What is the difference between the P3602ACRP and P3602ACLRP?

A: The primary differences are product status, packaging format, and regulatory compliance. The P3602ACRP is obsolete and supplied in bulk, while the P3602ACLRP is active and supplied in Tape & Reel format. The P3602ACLRP is ROHS3 compliant, whereas the P3602ACRP is RoHS non-compliant.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts have identical electrical specifications: 220V/440V breakover voltage, 170V/340V off-state voltage, 4V on-state voltage, 400A peak pulse current (8/20µs), 100A peak pulse current (10/1000µs), and 150mA hold current.

Q: Which part should be selected for new production designs?

A: The P3602ACLRP should be selected for new designs. It is the active product with current manufacturing support and ROHS3 compliance, making it the appropriate choice for ongoing production.

Q: Does the Tape & Reel packaging of the P3602ACLRP affect compatibility?

A: No. Tape & Reel packaging is a supply format that does not affect the electrical or mechanical characteristics of the component. The actual part remains identical to the bulk-packaged version.

Q: Are both parts suitable for high-current transient suppression applications?

A: Yes. Both the P3602ACRP and P3602ACLRP are rated for 400A peak pulse current in an 8/20µs waveform, making them suitable for transient voltage suppression in high-current applications requiring 170V/340V off-state voltage protection.
