Substitute Part Grouping Explanation

Substitute parts for the P6KE20CA-TP are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalents maintain identical electrical specifications across all critical parameters: 17.1V reverse standoff voltage, 19V minimum breakdown voltage, 27.7V maximum clamping voltage, 22A peak pulse current, and 600W peak pulse power. These parts are interchangeable in the same circuit application without performance deviation.

Similar Alternatives provide comparable overvoltage protection with variations in one or more electrical parameters while maintaining functional compatibility for general-purpose applications. These parts operate within acceptable tolerance ranges for voltage ratings and current handling but may differ in peak pulse power or current capacity.

Key substitution criteria:

Voltage - Reverse Standoff (Typ): 15.3V to 17.1V
Voltage - Clamping (Max) @ Ipp: 24.4V to 27.7V
Current - Peak Pulse (10/1000µs): 20.9A to 60A
Power - Peak Pulse: 500W to 1500W
Package / Case: DO-204AC, DO-15, Axial (Through Hole)

Engineering Selection Recommendations

Direct Substitutes (Identical Electrical Performance):

P6KE20CA (Fairchild Semiconductor), P6KE20CA-B (Littelfuse Inc.), and TP6KE20CA (Littelfuse Inc.) are direct electrical equivalents to the P6KE20CA-TP. All three maintain 17.1V reverse standoff voltage, 27.7V clamping voltage, 22A peak pulse current, and 600W peak pulse power. The primary distinction is packaging format: P6KE20CA-B is supplied in Bulk packaging, while TP6KE20CA is supplied in Cut Tape (CT) format. P6KE20CA-TP and TP6KE20CA both feature AEC-Q101 automotive qualification and ROHS3 compliance. Selection between these direct equivalents depends on procurement requirements and packaging compatibility with assembly processes.

Similar Alternatives (Comparable Performance):

P6KE18CA (Diotec Semiconductor) and SA15CA-B (Littelfuse Inc.) operate at lower voltage ratings (15.3V and 15V reverse standoff respectively) with reduced clamping voltages (25.2V and 24.4V). These parts are suitable for applications requiring protection at lower voltage thresholds. P6KE18CA maintains 600W peak pulse power with 25A peak pulse current, while SA15CA-B provides 500W peak pulse power with 20.9A peak pulse current.

1.5KE18CA (Taiwan Semiconductor Corporation) represents a higher-power alternative with 1500W peak pulse power and 60A peak pulse current, but operates in the DO-201 package rather than DO-15. This part is applicable only when circuit board layout accommodates the larger axial package form factor.

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original P6KE20CA-TP specification.

Frequently Asked Questions (FAQ)

Q: Can P6KE20CA replace P6KE20CA-TP directly?

A: Yes. P6KE20CA (Fairchild Semiconductor) is a direct electrical equivalent with identical voltage ratings (17.1V reverse standoff, 27.7V clamping), current capacity (22A), and power rating (600W). The only difference is the operating temperature lower limit (-50°C versus -55°C). For applications operating above -50°C, this part is fully interchangeable.

Q: What is the difference between P6KE20CA-B and TP6KE20CA?

A: Both are manufactured by Littelfuse Inc. and are direct electrical equivalents to P6KE20CA-TP with identical electrical specifications. The difference is packaging: P6KE20CA-B is supplied in Bulk format, while TP6KE20CA is supplied in Cut Tape (CT) format. TP6KE20CA also carries AEC-Q101 automotive qualification. Selection depends on assembly process requirements and procurement specifications.

Q: Can P6KE18CA be used instead of P6KE20CA-TP?

A: P6KE18CA is a similar alternative with lower voltage ratings (15.3V reverse standoff versus 17.1V, 25.2V clamping versus 27.7V). It is suitable only for applications where the lower voltage threshold is acceptable. The part maintains 600W peak pulse power and provides 25A peak pulse current. Circuit redesign or voltage threshold adjustment may be required.

Q: Why would 1.5KE18CA be considered as a substitute?

A: 1.5KE18CA provides significantly higher power handling (1500W peak pulse power versus 600W) and current capacity (60A versus 22A), making it suitable for high-energy transient suppression applications. However, it operates in the DO-201 package (larger axial form factor) rather than DO-15, requiring different circuit board layout and mounting considerations. This part is applicable only when the larger package footprint is accommodated.

Q: Are all substitute parts ROHS3 compliant?

A: P6KE20CA-TP, P6KE20CA-B, TP6KE20CA, and 1.5KE18CA are ROHS3 compliant. P6KE20CA (Fairchild Semiconductor) and P6KE18CA (Diotec Semiconductor) do not specify ROHS3 compliance in their documentation. SA15CA-B is ROHS3 compliant. Verify compliance requirements for your specific application before selection.

Q: What package compatibility should I consider?

A: P6KE20CA-TP, P6KE20CA, P6KE20CA-B, TP6KE20CA, P6KE18CA, and SA15CA-B all use DO-15 (DO-204AC) axial package and are mechanically interchangeable on through-hole circuit boards. 1.5KE18CA uses the larger DO-201 (DO-27) axial package and requires different board layout. Verify PCB footprint compatibility before substitution.
