Key Parameters

Substitute Part Grouping Explanation

The MSW01E8-4P-SR qualifies as a substitute for the KPT01F8-4P based on the following critical parameters that determine functional interchangeability:

Matching Parameters:

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

Acceptable Variations:

• Termination: Solder Cup (KPT01F8-4P) vs. Solder (MSW01E8-4P-SR) — both are solder-based termination methods compatible with the same connection methodology
• Shell Material: Aluminum Alloy (KPT01F8-4P) vs. Aluminum (MSW01E8-4P-SR) — functionally equivalent
• Voltage Rating: 600VAC, 850VDC (KPT01F8-4P) vs. 800V (MSW01E8-4P-SR) — MSW01E8-4P-SR meets or exceeds voltage requirements

Parameter Comparison

Engineering Selection Recommendations

Both the KPT01F8-4P and MSW01E8-4P-SR are active production parts classified under the same export control category (EAR99) and share identical RoHS non-compliance status. The MSW01E8-4P-SR meets all critical electrical and mechanical specifications required for direct substitution, including matching shell size, pin configuration, current capacity, and temperature operating range. The voltage rating of the substitute part (800V) exceeds the minimum requirement of the main part (600VAC, 850VDC), providing equivalent or superior performance in this parameter. Both connectors feature bayonet lock fastening and strain relief, ensuring mechanical compatibility in existing designs. Selection between these parts should be based on availability, lead time, and procurement requirements rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can MSW01E8-4P-SR be used as a direct replacement for KPT01F8-4P in existing assemblies?

A: Yes. Both connectors share identical shell size (8-4), pin count (4), connector type (receptacle with male pins), mounting configuration (free hanging in-line), and fastening method (bayonet lock). Electrical ratings are compatible, with the substitute part meeting or exceeding voltage and current specifications.

Q: What is the difference between "Solder Cup" and "Solder" termination?

A: Both termination methods are solder-based connection techniques. Solder Cup refers to a cup-shaped terminal designed for solder connection, while Solder indicates a general solder termination approach. Both are compatible with standard PCB assembly and wire attachment processes.

Q: Are there any compliance or certification differences between these parts?

A: Both parts share identical export control classification (EAR99) and RoHS compliance status (non-compliant). No compliance barriers exist for substitution.

Q: Does the shell material difference affect performance?

A: The KPT01F8-4P uses Aluminum Alloy while MSW01E8-4P-SR uses Aluminum. Both materials provide equivalent environmental resistance and mechanical durability for the specified operating temperature range (-55°C to 125°C).

Q: What is the voltage rating difference, and does it matter?

A: The KPT01F8-4P is rated for 600VAC and 850VDC, while MSW01E8-4P-SR is rated for 800V. The substitute part's rating is sufficient for applications requiring the main part's specifications.

Q: Are both parts available in the same packaging?

A: Both parts are supplied in Bag packaging. Inventory availability differs: KPT01F8-4P has 878 units in stock, while MSW01E8-4P-SR has 785 units in stock.
