P4KE200CA-TP Equivalent & Substitute Parts

Part Overview

The P4KE200CA-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 171V and provides clamping at 274V maximum, making it suitable for protecting circuits from transient overvoltage events. 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.

Substitute Part Grouping Explanation

Substitution eligibility for the P4KE200CA-TP is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 171V
• Voltage - Breakdown (Min): 190V
• Voltage - Clamping (Max) @ Ipp: 274V
• Current - Peak Pulse (10/1000µs): ≥1.5A
• Power - Peak Pulse: ≥400W
• Operating Temperature Range: -55°C to 175°C (TJ)
• Mounting Type: Through Hole
• Package / Case: DO-204AL or DO-41 compatible
• Type: Zener
• Bidirectional Channels: 1

The substitute part P4KE200CA meets all substitution criteria with identical voltage specifications and equivalent current handling capability (1.51A peak pulse current). Both parts share the same base product number (P4KE200), identical thermal operating range, and compatible axial through-hole packaging formats.

Parameter Comparison

Engineering Selection Recommendations

The P4KE200CA substitute part is functionally equivalent to the P4KE200CA-TP for circuit protection applications requiring 171V standoff voltage with 274V clamping performance. Both parts maintain active production status and full RoHS3 compliance, ensuring regulatory alignment and long-term availability. The substitute part demonstrates marginally higher peak pulse current capability (1.51A versus 1.5A), which provides additional operational margin within the same 400W power dissipation envelope. Packaging compatibility between DO-204AL and DO-41 formats permits direct board-level substitution without mechanical redesign. Selection between these parts should be based on supplier availability, lead time requirements, and procurement cost considerations, as electrical performance and thermal characteristics are equivalent across the specified operating range.

Frequently Asked Questions (FAQ)

Q: Can P4KE200CA be used as a direct replacement for P4KE200CA-TP?

A: Yes. Both parts share identical voltage specifications (171V standoff, 274V clamping), equivalent current ratings (1.5A and 1.51A respectively), and compatible through-hole axial packaging. Electrical performance and thermal operating range are equivalent.

Q: Are there packaging differences between these parts?

A: Both parts use DO-41 axial through-hole packaging. The main part specifies DO-204AL, DO-41, Axial formats, while the substitute specifies DO-204AL (DO-41) and Axial. These designations refer to the same physical package configuration and are mechanically interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both P4KE200CA-TP and P4KE200CA are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the difference in peak pulse current between these parts?

A: The main part (P4KE200CA-TP) is rated at 1.5A peak pulse current, while the substitute (P4KE200CA) is rated at 1.51A. This 0.01A difference is within normal manufacturing tolerance and does not affect circuit protection performance.

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

A: Yes. Identical voltage parameters, equivalent current handling, matching thermal ranges, and compatible through-hole packaging permit direct substitution without circuit redesign or board layout modification.

Q: What determines substitution eligibility for TVS diodes?

A: Substitution requires equivalence across voltage specifications (standoff, breakdown, and clamping), current ratings, power dissipation capability, operating temperature range, mounting type, and package format. Manufacturer differences do not affect substitution eligibility when all electrical and mechanical parameters match.
