KPT08F8-4P Equivalent & Substitute Parts

Part Overview

The KPT08F8-4P is a 4-position circular connector plug manufactured by ITT Cannon, LLC, featuring male pins with solder cup termination. This connector is designed for applications requiring bayonet lock fastening, operating across a temperature range of -55°C to 125°C with a current rating of 7.5A and voltage rating of 600VAC/850VDC. The connector is currently active in production and maintains an inventory of 795 pieces in new original condition. Substitute parts are identified when the main part becomes unavailable, when inventory constraints exist, or when equivalent electrical and mechanical specifications can satisfy application requirements.

Key Parameters

Substitute Part Grouping Explanation

The MSW08E8-4P-SR qualifies as a substitute for the KPT08F8-4P based on the following critical parameters that determine functional interchangeability:

Matching Parameters:

• Number of Positions: 4
• Shell Size - Insert: 8-4
• Connector Type: Plug, Male Pins
• Mounting Type: Free Hanging (In-Line), Right Angle
• Fastening Type: Bayonet Lock
• Current Rating: 7.5A
• Operating Temperature: -55°C to 125°C
• Ingress Protection: Environment Resistant
• Features: Strain Relief

Substitution Basis: The MSW08E8-4P-SR maintains electrical compatibility through equivalent current and voltage handling capabilities, identical connector positioning and shell sizing, and compatible operating temperature specifications. Both connectors employ bayonet lock fastening and right-angle mounting configurations, ensuring mechanical compatibility in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

Both the KPT08F8-4P and MSW08E8-4P-SR maintain identical product status as active components. Selection between these parts should be based on availability and inventory status. The KPT08F8-4P currently maintains 795 pieces in stock, while the MSW08E8-4P-SR maintains 959 pieces. Both connectors carry RoHS non-compliant status and EAR99 export classification. The MSW08E8-4P-SR is supplied in bag packaging, whereas packaging information for the KPT08F8-4P is not specified. Both parts satisfy equivalent electrical and mechanical requirements for applications requiring 4-position circular connectors with bayonet lock fastening and solder termination.

Frequently Asked Questions (FAQ)

Q: What determines if MSW08E8-4P-SR can replace KPT08F8-4P? A: Substitution is valid when the connector maintains identical shell size (8-4), position count (4), mounting configuration (right angle, free hanging), fastening type (bayonet lock), current rating (7.5A), and operating temperature range (-55°C to 125°C). Both parts meet these criteria.

Q: Are there differences in termination between these connectors? A: The KPT08F8-4P specifies solder cup termination, while the MSW08E8-4P-SR specifies solder termination. Both are solder-based termination methods compatible with equivalent soldering processes.

Q: What is the voltage compatibility between these parts? A: The KPT08F8-4P is rated for 600VAC and 850VDC. The MSW08E8-4P-SR is rated for 800V. The substitute part meets or exceeds the voltage requirements of the main part for DC applications and provides equivalent AC performance.

Q: Do packaging differences affect substitution? A: The MSW08E8-4P-SR is supplied in bag packaging. Packaging format does not affect electrical or mechanical compatibility; selection should be based on handling and storage requirements specific to your application.

Q: Are both parts compliant with RoHS regulations? A: Both the KPT08F8-4P and MSW08E8-4P-SR are RoHS non-compliant. If RoHS compliance is required for your application, neither part is suitable without verification of alternative options.
