KPT08F8-2P Equivalent & Substitute Parts

Part Overview

The KPT08F8-2P is a 2-position circular connector plug manufactured by ITT Cannon, LLC, featuring male pins with solder cup termination. This active product is designed for applications requiring bayonet lock fastening, gold-plated mating contacts, and operation across -55°C to 125°C temperature ranges. The connector is specified for 7.5A current and 600VAC/850VDC voltage ratings with olive drab cadmium shell finish. Substitute parts are identified when equivalent electrical and mechanical parameters are available from alternative manufacturers, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KPT08F8-2P is determined by strict alignment of the following critical parameters:

• Connector Type & Position Count: Plug configuration with 2 positions
• Shell Size - Insert: 8-2 specification for mechanical compatibility
• Mounting Type: Free hanging (in-line) and right angle orientation
• Fastening Type: Bayonet lock mechanism
• Electrical Ratings: Current capacity of 7.5A and voltage tolerance of 600VAC minimum
• Operating Temperature Range: -55°C to 125°C
• Termination Method: Solder-based connection (solder cup or solder termination)
• Environmental Protection: Environment resistant classification
• Strain Relief: Presence of strain relief feature

The MSW08E8-2P-SR meets these substitution criteria across all critical parameters, enabling direct functional equivalence in applications requiring KPT08F8-2P performance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the KPT08F8-2P and MSW08E8-2P-SR are active products with identical RoHS non-compliance status and EAR99 export classification. Selection between these parts should be based on:

• Availability: KPT08F8-2P has 967 units in stock; MSW08E8-2P-SR has 1048 units in stock
• Contact Finish: KPT08F8-2P specifies gold plating (50.0µin/1.27µm thickness); MSW08E8-2P-SR specifies cadmium plating
• Voltage Specification: KPT08F8-2P rated for 600VAC/850VDC; MSW08E8-2P-SR rated for 800V
• Shell Finish: KPT08F8-2P features olive drab cadmium; MSW08E8-2P-SR features cadmium without color specification

Both parts satisfy the core electrical and mechanical requirements for 2-position, 7.5A, bayonet-lock circular connector applications across the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can MSW08E8-2P-SR directly replace KPT08F8-2P in existing designs?

A: Yes, provided the application does not require the specific contact finish (gold plating) or shell finish (olive drab) of the original part. Both connectors meet the 2-position, 7.5A, bayonet lock, and -55°C to 125°C specifications.

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

A: KPT08F8-2P uses gold plating at 50.0µin (1.27µm) thickness on mating contacts. MSW08E8-2P-SR uses cadmium plating. Gold plating typically provides superior corrosion resistance and lower contact resistance in high-reliability applications.

Q: Are both parts suitable for military applications?

A: Both parts are RoHS non-compliant and carry EAR99 export classification. MSW08E8-2P-SR is explicitly listed for military applications. Compliance with specific military standards should be verified against application requirements.

Q: What is the difference in termination between solder cup and solder?

A: Both parts use solder-based termination. Solder cup termination (KPT08F8-2P) provides a cup-shaped receptacle for wire insertion and soldering. Solder termination (MSW08E8-2P-SR) indicates standard solder connection points. Both methods achieve equivalent electrical connection.

Q: How do the voltage ratings compare?

A: KPT08F8-2P is rated for 600VAC and 850VDC. MSW08E8-2P-SR is rated for 800V. The MSW08E8-2P-SR rating is sufficient for applications requiring up to 800V operation. Verify application voltage requirements before substitution.
