P4KE220A-TP Equivalent & Substitute Parts

Part Overview

The P4KE220A-TP is a unidirectional transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This through-hole component operates with a reverse standoff voltage of 185V and provides clamping at 328V maximum, making it suitable for protecting sensitive electronic circuits from transient voltage 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.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P4KE220A-TP are qualified based on the following critical parameters that must remain constant:

• Voltage - Reverse Standoff (Typ): 185V
• Voltage - Breakdown (Min): 209V
• Voltage - Clamping (Max) @ Ipp: 328V
• Current - Peak Pulse (10/1000µs): 1.3A
• Power - Peak Pulse: 400W
• Operating Temperature Range: -55°C to 175°C (TJ)
• Mounting Type: Through Hole
• Package / Case: DO-204AL, DO-41, Axial
• Type: Zener
• Unidirectional Channels: 1

The P4KE220A manufactured by Taiwan Semiconductor Corporation qualifies as a direct substitute because it maintains identical electrical specifications and mechanical compatibility while offering the same functional performance in general-purpose transient voltage suppression applications.

Parameter Comparison

Engineering Selection Recommendations

Both the P4KE220A-TP (Micro Commercial Co) and P4KE220A (Taiwan Semiconductor Corporation) are active production components with identical electrical and mechanical specifications. Selection between these parts may be based on:

• Availability: Taiwan Semiconductor Corporation variant shows higher inventory (60,100 pcs) compared to Micro Commercial Co variant (959 pcs)
• Supplier preference and lead time requirements
• Procurement agreements or qualification requirements with specific manufacturers
• Cost considerations between manufacturers

Both parts maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory compliance in end applications. The identical parameter set ensures direct functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can P4KE220A from Taiwan Semiconductor Corporation replace P4KE220A-TP from Micro Commercial Co?

A: Yes. Both parts share identical electrical specifications (185V standoff, 328V clamping, 1.3A peak pulse current, 400W peak power) and mechanical compatibility (through-hole DO-41/DO-204AL package). They are functionally equivalent for general-purpose transient voltage suppression applications.

Q: What are the critical parameters that determine substitution eligibility?

A: The following parameters must match exactly: reverse standoff voltage (185V), breakdown voltage (209V minimum), clamping voltage (328V maximum), peak pulse current (1.3A), peak pulse power (400W), operating temperature range (-55°C to 175°C), mounting type (through hole), and package designation (DO-204AL/DO-41 axial).

Q: Are there package differences between these parts?

A: Both parts use the same package family: DO-204AL, DO-41, Axial. The supplier device package designation differs slightly (DO-41 for Micro Commercial Co vs. DO-204AL (DO-41) for Taiwan Semiconductor Corporation), but these refer to the same physical package standard and are mechanically interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both P4KE220A-TP and P4KE220A are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use.

Q: What is the difference between the base product number and the full part number?

A: The base product number P4KE220 identifies the core product line. The full part number P4KE220A includes the voltage rating designation (A suffix), and the -TP suffix on the Micro Commercial Co variant indicates tape and reel packaging format. Both variants share the same base product designation.
