Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP90A-E3/73 are qualified based on the following critical parameters that determine functional equivalence:

• Voltage - Reverse Standoff (Typ): 90V
• Voltage - Breakdown (Min): 100V minimum
• Voltage - Clamping (Max) @ Ipp: 146V maximum
• Unidirectional Channels: 1
• Type: Zener
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• RoHS Status: ROHS3 Compliant

Substitute parts may vary in peak pulse current rating, power dissipation capability, packaging configuration (P600 vs. R-6), and manufacturer identity while maintaining the core voltage protection characteristics. Parts with higher power ratings (15kW vs. 5kW) are acceptable substitutes as they provide equivalent or superior transient suppression performance within the specified voltage window.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance, meeting regulatory requirements for current applications. The 5KP90A (Littelfuse) provides direct electrical and mechanical equivalence with identical voltage parameters and P600 packaging, making it the primary substitute when sourcing from alternative manufacturers is required.

The 15KP90A-TP (Micro Commercial Co) and 15KPA90A (MDE Semiconductor) are qualified substitutes with enhanced power dissipation ratings (15kW vs. 5kW). These parts maintain voltage protection specifications within acceptable tolerances and are suitable for applications requiring higher transient energy absorption. The 15KPA90A offers the highest peak pulse current capability (103.7A) among the substitute options.

Package configuration differences exist between P600 (5KP90A-E3/73, 5KP90A, 15KPA90A) and R-6 (15KP90A-TP) formats. PCB layout and mechanical mounting considerations must account for these package variations during component substitution.

Frequently Asked Questions (FAQ)

Q: Can the 5KP90A (Littelfuse) be used as a direct replacement for the 5KP90A-E3/73?

A: Yes. The 5KP90A maintains identical voltage specifications (90V reverse standoff, 100V breakdown minimum, 146V clamping maximum), equivalent peak pulse current (34.9A vs. 34.2A), matching power rating (5kW), and identical P600 axial package configuration. Electrical and mechanical compatibility is confirmed.

Q: What is the difference between 5kW and 15kW power-rated substitutes?

A: The 15KP90A-TP and 15KPA90A provide higher peak pulse power dissipation capability (15kW vs. 5kW). Both maintain the same voltage protection window (90V standoff, 146V clamping). Higher power ratings allow these parts to suppress larger transient energy events without exceeding maximum junction temperature limits. Selection depends on application transient energy requirements.

Q: Are package differences between P600 and R-6 significant for substitution?

A: Yes. The P600 and R-6 are different axial package formats with distinct physical dimensions and lead configurations. PCB footprint, mounting hole spacing, and component placement must be verified before substituting between these packages. Mechanical compatibility with existing PCB designs is required.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All listed substitute parts are ROHS3 compliant and carry EAR99 ECCN classification. Moisture sensitivity level is 1 (Unlimited) for all parts. REACH status is either REACH Unaffected or available upon request, confirming regulatory compliance across all options.

Q: Can the 15KPA90A be used in place of the 5KP90A-E3/73?

A: Yes. The 15KPA90A maintains voltage specifications within acceptable tolerance (90V standoff, 100.5V breakdown, 145.6V clamping) and operates within the same temperature range. The higher peak pulse current (103.7A) and power rating (15kW) provide enhanced transient suppression capability. P600 package compatibility with the original part is confirmed.
