5KP9.0A-G Equivalent & Substitute Parts

Part Overview

The 5KP9.0A-G is a unidirectional Zener-type transient voltage suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose overvoltage protection applications. This through-hole component features a 9V reverse standoff voltage with a 15.4V maximum clamping voltage and 5kW peak pulse power rating. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to address inventory availability, packaging preferences, or supply chain requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP9.0A-G is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Voltage - Reverse Standoff (Typ): 9V
• Voltage - Breakdown (Min): 10V
• Voltage - Clamping (Max) @ Ipp: 15.4V
• Power - Peak Pulse: 5000W (5kW)
• Type: Zener
• Unidirectional Channels: 1

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole
• Package / Case: R-6, Axial

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The substitute part 5KP9.0A-TP meets all electrical and mechanical compatibility criteria. Differences in packaging format (Cut Tape vs. Tape & Box) and operating temperature range do not affect functional substitution in general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 5KP9.0A-G and 5KP9.0A-TP are active production components with identical electrical specifications and mechanical form factors. Selection between these parts should be based on:

Availability and Lead Time: The 5KP9.0A-TP offers higher inventory availability (6278 pcs vs. 830 pcs), making it suitable for applications requiring expedited procurement.

Packaging Requirements: The 5KP9.0A-G is supplied in Tape & Box format, while the 5KP9.0A-TP is supplied in Cut Tape format. Choose based on assembly line requirements and tape reel compatibility.

Temperature Operating Range: The 5KP9.0A-TP supports operation to 175°C junction temperature, compared to 150°C for the 5KP9.0A-G. For applications operating near thermal limits, the substitute part provides additional margin.

Compliance: Both parts meet ROHS3 and REACH requirements, ensuring regulatory compliance for commercial and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the 5KP9.0A-TP directly replace the 5KP9.0A-G in existing designs?

A: Yes. Both parts share identical electrical specifications (9V standoff, 15.4V clamping, 5kW peak power) and mechanical form factors (R-6 axial through-hole package). No circuit modifications are required.

Q: What is the difference between Tape & Box and Cut Tape packaging?

A: Tape & Box (TB) packaging includes a protective box for storage and handling, suitable for lower-volume applications. Cut Tape (CT) packaging provides individual tape segments, optimized for high-volume automated assembly. Both formats contain the same component on standard 0.5-inch pitch tape.

Q: Are there any thermal performance differences between these parts?

A: The 5KP9.0A-TP supports a maximum junction temperature of 175°C, while the 5KP9.0A-G is rated to 150°C. This difference does not affect performance in typical general-purpose applications operating below 100°C ambient temperature.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 5KP9.0A-G and 5KP9.0A-TP are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for commercial and industrial electronics.

Q: What determines whether a part can substitute for the 5KP9.0A-G?

A: Substitution requires matching the following parameters: 9V reverse standoff voltage, 10V minimum breakdown voltage, 15.4V maximum clamping voltage, 5kW peak pulse power, Zener type, single unidirectional channel, through-hole mounting, and R-6 axial package format.
