KPT07E8-4P Equivalent & Substitute Parts

Part Overview

The KPT07E8-4P is a 4-position circular connector receptacle manufactured by ITT Cannon, LLC, designed for military and industrial applications requiring robust environmental resistance. This connector features male pins with solder cup termination, bayonet lock fastening, and operates across a wide temperature range of -55°C to 125°C. The part is currently active in production with 1005 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part may be unavailable or require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KPT07E8-4P is determined by strict alignment of the following critical parameters:

• Position Count: Must be 4 positions
• Shell Size: Must be 8-4 insert designation
• Mounting Configuration: Panel mount with bulkhead front side nut
• Fastening Mechanism: Bayonet lock
• Electrical Ratings: Current rating of 7.5A and voltage rating of 800V or higher
• Operating Temperature Range: -55°C to 125°C minimum
• Environmental Classification: Environment resistant designation
• Termination Method: Solder-based termination (solder cup or solder acceptable)

The MSW07E8-4P from Milspecwest, LLC meets these substitution criteria. Both connectors share identical position count, shell size, mounting type, fastening mechanism, current rating, temperature range, and environmental resistance classification. Voltage rating compatibility is confirmed (KPT07E8-4P: 600VAC/850VDC; MSW07E8-4P: 800V). Both employ solder-based termination methods suitable for equivalent circuit integration.

Parameter Comparison

Engineering Selection Recommendations

Both the KPT07E8-4P and MSW07E8-4P are active production components with equivalent electrical and mechanical specifications. Selection between these parts should be based on:

Compliance Requirements: Both parts are RoHS non-compliant. Applications requiring RoHS compliance cannot use either component.

Contact Finish Consideration: The KPT07E8-4P features gold mating contact finish (50.0µin/1.27µm thickness), while the MSW07E8-4P uses cadmium contact finish. Gold plating provides superior corrosion resistance and lower contact resistance in low-signal applications. Cadmium finish is suitable for standard industrial and military environments.

Shell Finish: The KPT07E8-4P specifies olive drab cadmium finish, while the MSW07E8-4P uses standard cadmium finish. Both provide equivalent environmental protection for the specified operating temperature range.

Inventory Availability: KPT07E8-4P has 1005 units in stock; MSW07E8-4P has 1003 units in stock. Both are readily available.

Series Compatibility: The MSW07E8-4P is designated as a 26482 Style Connector, which aligns with the KPT07E8-4P's 26482 - STYLE SERIES I & MIL BAT classification, confirming mechanical and electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MSW07E8-4P directly replace the KPT07E8-4P in existing assemblies?

A: Yes, the MSW07E8-4P meets all critical substitution parameters: identical position count (4), shell size (8-4), mounting configuration, fastening mechanism, current rating (7.5A), voltage rating (800V exceeds 850VDC requirement), and operating temperature range (-55°C to 125°C). Both employ solder-based termination suitable for equivalent circuit integration.

Q: What is the difference in contact finish between these two parts?

A: The KPT07E8-4P uses gold mating contact finish with 50.0µin thickness, providing enhanced corrosion resistance and lower contact resistance. The MSW07E8-4P uses cadmium contact finish. Gold finish is preferred for applications requiring superior signal integrity or extended service life in cor
