Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP190C is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 190V
• Voltage - Clamping (Max) @ Ipp: Must not exceed 325.5V
• Power - Peak Pulse: 5000W (5kW)
• Bidirectional Channels: 1
• Mounting Type: Through Hole
• Package / Case: P600, Axial
• Operating Temperature Range: -55°C ~ 175°C (TJ)

The 5KP190CA qualifies as a direct substitute. Both components share identical reverse standoff voltage, peak pulse power rating, mounting configuration, and thermal operating range. The 5KP190CA maintains compatibility with the same P600 axial package and through-hole mounting requirements.

Parameter Comparison

Engineering Selection Recommendations

The 5KP190CA is the direct substitute for the obsolete 5KP190C. Both components are manufactured by Littelfuse Inc. within the 5KP series and maintain identical electrical performance specifications for reverse standoff voltage, peak pulse power rating, and thermal operating range.

The 5KP190CA is classified as Active product status, ensuring ongoing availability and supply chain support. Both components meet ROHS3 compliance requirements and carry MSL 1 (Unlimited) moisture sensitivity classification, indicating equivalent handling and storage requirements.

The 5KP190CA features a lower maximum clamping voltage (310V versus 325.5V), which provides improved voltage regulation performance while maintaining full compatibility with the P600 axial through-hole package configuration.

Frequently Asked Questions (FAQ)

Q: Can the 5KP190CA directly replace the 5KP190C in existing designs?

A: Yes. Both components share identical reverse standoff voltage (190V), peak pulse power rating (5000W), operating temperature range (-55°C ~ 175°C), and P600 axial through-hole package configuration. The 5KP190CA is the manufacturer-designated substitute.

Q: What is the difference in clamping voltage between these parts?

A: The 5KP190C specifies a maximum clamping voltage of 325.5V, while the 5KP190CA specifies 310V. The lower clamping voltage of the 5KP190CA represents improved voltage regulation performance within the same power rating.

Q: Are there any compliance or certification differences?

A: Both components are ROHS3 compliant and carry identical MSL 1 (Unlimited) moisture sensitivity ratings. No compliance or certification differences exist between the two parts.

Q: What is the product status difference?

A: The 5KP190C is classified as Obsolete, while the 5KP190CA is Active. The 5KP190CA ensures continued availability and manufacturer support for new designs and production requirements.

Q: Are the packages identical?

A: Yes. Both components use the P600 axial through-hole package configuration, ensuring mechanical and electrical compatibility in PCB layouts and circuit designs.
