Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP7.0CA-B are identified based on strict electrical and mechanical parameter matching within the 5KP series. The substitution criteria are:

• Identical voltage ratings: 7V reverse standoff, 7.78V minimum breakdown, 12V maximum clamping voltage
• Identical current and power specifications: 425A peak pulse current, 5000W peak pulse power
• Identical package and mounting: P600 axial through-hole configuration
• Identical operating temperature range: -55°C to 175°C
• Identical compliance certifications: ROHS3 Compliant, REACH Unaffected

The primary difference between the main part and substitute is the packaging format: the 5KP7.0CA-B is supplied in bulk packaging, while the 5KP7.0CA substitute is supplied in Tape & Reel (TR) format. Both parts are manufactured by Littelfuse Inc. and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the 5KP7.0CA-B and 5KP7.0CA are active products manufactured by Littelfuse Inc. with identical electrical performance and mechanical specifications. Selection between these parts depends on procurement and assembly requirements:

The 5KP7.0CA-B in bulk packaging is suitable for manual assembly, prototyping, or low-volume applications where individual component handling is standard practice.

The 5KP7.0CA in Tape & Reel format is suitable for automated assembly processes, high-volume production runs, and applications requiring component feeding through pick-and-place equipment.

Both parts maintain full ROHS3 compliance and REACH compliance status, ensuring regulatory alignment for commercial and industrial applications. The identical operating temperature range of -55°C to 175°C supports deployment across standard industrial and extended temperature environments.

Frequently Asked Questions (FAQ)

Q: Can the 5KP7.0CA (Tape & Reel) be used as a direct replacement for the 5KP7.0CA-B (Bulk)?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. The 5KP7.0CA in Tape & Reel format can be manually removed and used in applications originally designed for the bulk-packaged 5KP7.0CA-B.

Q: Are there any performance differences between bulk and Tape & Reel packaging?

A: No. The component itself is identical. Tape & Reel packaging is designed for automated assembly processes and does not affect electrical or thermal performance.

Q: What is the significance of the P600 package designation?

A: P600 refers to the axial through-hole package configuration. Both the main part and substitute use this identical package, ensuring mechanical compatibility with existing PCB designs and assembly processes.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both the 5KP7.0CA-B and 5KP7.0CA operate across the full temperature range of -55°C to 175°C junction temperature, supporting deployment in industrial and automotive environments.

Q: What does ROHS3 compliance indicate?

A: ROHS3 compliance confirms that both parts meet the Restriction of Hazardous Substances Directive, restricting the use of specific hazardous materials in electrical and electronic equipment. Both parts are fully compliant.
