P4KE220 Equivalent & Substitute Parts

Part Overview

The P4KE220 is a unidirectional transient voltage suppressor (TVS) diode in DO-204AL (DO-41) axial package, rated for 185V reverse standoff voltage and 400W peak pulse power. Manufactured by Littelfuse Inc., this component is classified as obsolete. Due to its obsolete status, equivalent substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term component availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P4KE220 are qualified based on the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 185V
• Voltage - Clamping (Max) @ Ipp: 328V to 344.4V
• Current - Peak Pulse (10/1000µs): 1.2A to 1.3A
• Power - Peak Pulse: 400W
• Operating Temperature Range: -55°C to 150°C minimum (175°C preferred)
• Mounting Type: Through Hole
• Package / Case: DO-204AL or DO-41 Axial
• Type: Zener, Unidirectional

All substitute parts maintain the same reverse standoff voltage and peak pulse power rating. Clamping voltage variations (328V to 344.4V) and peak pulse current variations (1.2A to 1.3A) remain within acceptable operating margins for general-purpose transient voltage suppression applications. All substitutes are available from active manufacturers with current product status.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are from active manufacturers with current product status, ensuring long-term availability and supply chain continuity. Selection criteria are based on the following factors:

For General-Purpose Applications: P4KE220A (Taiwan Semiconductor Corporation), P4KE220A-AP, P4KE220A-BP, or P4KE220A-TP (Micro Commercial Co) are suitable direct replacements. These parts maintain full electrical equivalence with the original P4KE220 and support the complete operating temperature range of -55°C to 175°C.

For Tape & Reel Packaging: P4KE220A-E3/54 and P4KE220AHE3/54 (Vishay General Semiconductor - Diodes Division) or P4KE220A-TP (Micro Commercial Co) are recommended for automated assembly processes. Both Vishay parts are RoHS3 compliant and REACH unaffected.

For Automotive Applications: P4KE220AHE3/54 (Vishay General Semiconductor - Diodes Division) is qualified to AEC-Q101 automotive standards and carries automotive-grade designation, suitable for automotive transient voltage suppression circuits.

For Bulk Packaging: P4KE220A-AP and P4KE220A-BP (Micro Commercial Co) or P4KE220A-G (Comchip Technology) are available in bulk packaging. Note that P4KE220A-G operates at a reduced maximum temperature of -55°C to 150°C, which may limit suitability for high-temperature applications.

All substitute parts maintain RoHS3 compliance and are classified under ECCN EAR99 with HTSUS code 8541.10.0080.

Frequently Asked Questions (FAQ)

Q: Can P4KE220A-E3/54 replace P4KE220 in all applications?

A: Yes. P4KE220A-E3/54 maintains the same reverse standoff voltage (185V) and peak pulse power (400W). The clamping voltage is 328V versus the original 344.4V, and peak pulse current is 1.2A versus 1.3A. These variations remain within acceptable operating margins for general-purpose transient voltage suppression. The part is RoHS3 compliant and REACH unaffected.

Q: What is the difference between P4KE220A-AP and P4KE220A-TP?

A: Both parts are manufactured by Micro Commercial Co and are electrically identical. The primary difference is packaging: P4KE220A-AP is supplied in bulk, while P4KE220A-TP is supplied in Tape & Reel (TR) format. Select based on assembly process requirements.

Q: Is P4KE220AHE3/54 suitable for automotive applications?

A: Yes. P4KE220AHE3/54 is qualified to AEC-Q101 automotive standards and carries automotive-grade designation. It is suitable for automotive transient voltage suppression circuits requiring automotive qualification.

Q: Why does P4KE220A-G have a lower maximum operating temperature?

A: P4KE220A-G (Comchip Technology) operates at -55°C to 150°C, compared to -55°C to 175°C for other substitutes. This reduced temperature range may limit its use in high-temperature applications. Verify application temperature requirements before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Most substitute parts are RoHS3 compliant. P4KE220A-AP and P4KE220A-BP do not list RoHS status in provided specifications. Confirm RoHS compliance requirements with the manufacturer or supplier before final selection.

Q: Can I use P4KE220A in place of P4KE220 for new production?

A: Yes. P4KE220A (Taiwan Semiconductor Corporation) is an active product with full electrical equivalence to P4KE220. It is suitable for new production designs and maintains the complete operating temperature range of -55°C to 175°C.
