P4KE440CA-TP Equivalent & Substitute Parts

Part Overview

The P4KE440CA-TP is a Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose voltage protection applications. This through-hole component operates with a reverse standoff voltage of 376V and provides clamping at 602V maximum, making it suitable for transient suppression in industrial and commercial electronics. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P4KE440CA-TP is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 376V
• Voltage - Breakdown (Min): 418V
• Voltage - Clamping (Max) @ Ipp: 600V to 602V range
• Current - Peak Pulse (10/1000µs): 680mA to 690mA range
• Power - Peak Pulse: 400W
• Operating Temperature Range: -55°C to 175°C (TJ)
• Mounting Type: Through Hole
• Package / Case: DO-204AL or DO-41 (equivalent axial packages)
• Type: Zener
• Bidirectional Channels: 1

The P4KE440CA manufactured by Taiwan Semiconductor Corporation qualifies as a direct substitute based on matching all critical electrical parameters within acceptable tolerances and maintaining identical mechanical compatibility through the DO-204AL (DO-41) package designation.

Parameter Comparison

Engineering Selection Recommendations

Both the P4KE440CA-TP and P4KE440CA meet identical regulatory and compliance requirements. Both components carry ROHS3 compliance and REACH unaffected status, ensuring suitability for regulated markets. The P4KE440CA-TP is currently in active production with 1020 units in stock, while the P4KE440CA substitute from Taiwan Semiconductor Corporation is also in active production with 630 units available. Selection between these parts should be based on inventory availability, lead time requirements, and supply chain considerations, as electrical and mechanical performance are equivalent within specified tolerances.

Frequently Asked Questions (FAQ)

Q: Can the P4KE440CA from Taiwan Semiconductor Corporation directly replace the P4KE440CA-TP from Micro Commercial Co?

A: Yes. Both components share identical reverse standoff voltage (376V), breakdown voltage (418V minimum), and operating temperature range (-55°C to 175°C). The clamping voltage and peak pulse current specifications differ by less than 1%, which is within normal manufacturing tolerance for TVS diodes in this class. Both use equivalent DO-204AL (DO-41) axial through-hole packages.

Q: Are there any package compatibility concerns?

A: No. Both parts use the DO-204AL designation, which is electrically and mechanically equivalent to the DO-41 package. Axial lead spacing and component dimensions are standardized for this package type, ensuring direct board-level compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the P4KE440CA-TP and P4KE440CA are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for industrial and commercial applications.

Q: What is the significance of the 2V difference in clamping voltage (602V vs 600V)?

A: This 2V difference represents approximately 0.33% variance and falls within standard manufacturing tolerances for TVS diodes. Both specifications ensure equivalent transient suppression performance in general-purpose applications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The electrical parameters, thermal characteristics, and mechanical package specifications are equivalent. No circuit redesign or board layout modification is required for substitution.
