Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PT00A-8-4P is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle with Male Pins
• Number of Positions: 4
• Shell Size - Insert: 8-4
• Mounting Type: Panel Mount with Flange
• Fastening Type: Bayonet Lock
• Operating Temperature Range: -55°C to 125°C
• Series Compliance: MIL-DTL-26482 Style or equivalent

Allowable Variations:

• Shell Finish: Cadmium or Olive Drab Chromate over Cadmium
• Contact Finish - Mating: Gold or Cadmium
• Termination Method: Solder Cup or Solder (without cup specification)
• Packaging Format: Bulk or Bag

The MSW00A8-4P from Milspecwest, LLC qualifies as a substitute part based on conformance to these critical parameters across all mandatory categories.

Parameter Comparison

Engineering Selection Recommendations

PT00A-8-4P Selection Criteria:

• Primary choice for applications requiring gold-plated mating contacts
• Specified for aerospace and military applications with strict contact finish requirements
• Olive Drab Chromate over Cadmium finish provides enhanced corrosion resistance
• Solder cup termination design for direct wire attachment
• Active product status with established supply chain (934 units in inventory)

MSW00A8-4P Selection Criteria:

• Suitable for military applications where cadmium contact finish is acceptable
• Provides documented current rating (7.5A) and voltage rating (800V) specifications
• Cadmium shell finish meets MIL-DTL-26482 style requirements
• Solder termination compatible with standard PCB assembly processes
• Active product status with available inventory (908 units)

Both parts maintain active product status, RoHS non-compliance, and EAR99 export classification. Selection between these parts depends on specific application requirements regarding contact finish (gold versus cadmium) and documented electrical ratings.

Frequently Asked Questions (FAQ)

Q: Can MSW00A8-4P directly replace PT00A-8-4P in existing designs?

A: MSW00A8-4P is mechanically and electrically compatible based on matching shell size (8-4), position count (4), mounting configuration (panel mount flange), fastening type (bayonet lock), and operating temperature range (-55°C to 125°C). The primary difference is contact finish (cadmium versus gold). Substitution is valid where gold plating is not a design requirement.

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

A: Solder cup termination on the PT00A-8-4P features a cup-shaped contact designed for direct wire insertion and solder attachment. The MSW00A8-4P solder termination uses standard solder connection points. Both methods are compatible with standard soldering processes; the choice depends on wire gauge and assembly procedure specifications.

Q: Are both parts compliant with MIL-DTL-26482?

A: PT00A-8-4P is specified as MIL-DTL-26482 Series I, PT. MSW00A8-4P is specified as 26482 Style Connectors. Both conform to the MIL-DTL-26482 standard framework for circular connectors with matching shell size, position count, and bayonet lock fastening.

Q: What are the electrical specifications for PT00A-8-4P?

A: Current and voltage ratings are not provided in the product specification for PT00A-8-4P. MSW00A8-4P provides documented ratings of 7.5A at 800V. For applications requiring specific electrical performance data, contact the manufacturer or refer to detailed specification sheets.

Q: Do both parts have the same packaging?

A: PT00A-8-4P is supplied in Bulk packaging (934 units in stock). MSW00A8-4P is supplied in Bag packaging (908 units in stock). Packaging format does not affect connector compatibility; selection depends on procurement and inventory management requirements.

Q: What is the operating temperature range for these connectors?

A: Both PT00A-8-4P and MSW00A8-4P operate across the identical temperature range of -55°C to 125°C, suitable for aerospace, military, and industrial applications requiring extended thermal performance.

Q: Are there any export restrictions on these parts?

A: Both PT00A-8-4P and MSW00A8-4P are classified under ECCN EAR99, indicating they are subject to export control regulations. Compliance with applicable export laws is required for international shipment.
