Key Parameters

Substitute Part Grouping Explanation

The MSW00E12-3P-SR qualifies as a substitute for the KPT00F12-3P based on the following critical parameters:

Matching Parameters:

• Number of Positions: 3
• Shell Size - Insert: 12-3
• Connector Type: Receptacle, Male Pins
• Mounting Type: Panel Mount
• Mounting Feature: Flange
• Fastening Type: Bayonet Lock
• Current Rating: 13A
• Operating Temperature: -55°C ~ 125°C
• Ingress Protection: Environment Resistant
• Features: Strain Relief
• Product Status: Active

Allowable Variations:

• Termination: Solder Cup (KPT00F12-3P) vs. Solder (MSW00E12-3P-SR) — both are solder-based termination methods
• Shell Material: Aluminum Alloy (KPT00F12-3P) vs. Aluminum (MSW00E12-3P-SR) — both are aluminum construction
• Shell Finish: Olive Drab Cadmium (KPT00F12-3P) vs. Cadmium (MSW00E12-3P-SR) — both provide corrosion protection
• Contact Finish: Gold (KPT00F12-3P) vs. Cadmium (MSW00E12-3P-SR) — both are conductive finishes
• Voltage Rating: 1000VAC, 1400VDC (KPT00F12-3P) vs. 800V (MSW00E12-3P-SR) — substitute meets minimum voltage requirements for most applications

Parameter Comparison

Engineering Selection Recommendations

Both the KPT00F12-3P and MSW00E12-3P-SR are active production parts with identical product status. Both parts are RoHS non-compliant and classified under ECCN EAR99. Selection between these parts should be based on:

Primary Considerations:

• Voltage requirement: The KPT00F12-3P supports 1000VAC and 1400VDC, while the MSW00E12-3P-SR supports 800V. Applications requiring voltages above 800V necessitate the KPT00F12-3P.
• Contact finish specification: The KPT00F12-3P provides gold-plated contacts, while the MSW00E12-3P-SR provides cadmium-plated contacts. Gold plating offers superior corrosion resistance and lower contact resistance.
• Availability: KPT00F12-3P has 1015 units in stock; MSW00E12-3P-SR has 1057 units in stock.
• Termination method: Both use solder-based termination; the KPT00F12-3P specifies solder cup while the MSW00E12-3P-SR specifies solder termination.

Frequently Asked Questions (FAQ)

Q: Can MSW00E12-3P-SR be used as a direct replacement for KPT00F12-3P?

A: MSW00E12-3P-SR is functionally equivalent for applications operating at 800V or below. For applications requiring the full voltage rating of 1000VAC or 1400VDC, the KPT00F12-3P is required.

Q: What are the key compatibility factors between these parts?

A: Both connectors share identical shell size (12-3), position count (3), mounting configuration (panel mount with flange), fastening method (bayonet lock), current rating (13A), and operating temperature range (-55°C to 125°C). These parameters ensure mechanical and electrical compatibility in equivalent applications.

Q: How do the contact finishes differ?

A: The KPT00F12-3P uses gold plating (50.0µin thickness) for superior corrosion resistance and lower contact resistance. The MSW00E12-3P-SR uses cadmium plating, which provides adequate corrosion protection for most military and industrial applications.

Q: Are there packaging differences?

A: The KPT00F12-3P packaging is not specified in the data. The MSW00E12-3P-SR is supplied in bag packaging.

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

A: Both are solder-based termination methods suitable for PCB assembly. Solder cup termination typically provides a cup-shaped contact for wire insertion before soldering, while solder termination refers to general solder-based connection methods. Both methods are compatible with standard PCB soldering processes.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS non-compliant and classified under ECCN EAR99. Both are rated for military applications with environment-resistant construction and strain relief features.
