Substitute Part Grouping Explanation

Substitute parts for the MS3475L8-33P are selected based on strict electrical and mechanical compatibility criteria. The following parameters must match or be equivalent across all substitute candidates:

Critical Matching Parameters:

• Number of Positions: 3
• Shell Size - Insert: 8-33
• Connector Type: Plug, Male Pins
• Termination: Crimp
• Fastening Type: Bayonet Lock
• Mounting Type: Free Hanging (In-Line)
• Current Rating: 7.5A
• Orientation: N (Normal)
• Contact Material: Copper Alloy
• Contact Finish - Mating: Gold

Acceptable Variation Parameters:

• Shell Material: Aluminum or Aluminum Alloy
• Shell Finish: Electroless Nickel, Nickel, or Chromate over Cadmium
• Operating Temperature: Must support minimum -55°C to 125°C (original supports -55°C to 200°C)
• Shielding: Shielded or Unshielded (functional equivalence depends on application)
• Insert Material: Plastic or Polychloroprene
• Ingress Protection: Environment Resistant or IP67

The substitute parts listed below satisfy these criteria and provide functional equivalence for the MS3475L8-33P in standard applications.

Engineering Selection Recommendations

KPSE6E833P-DN-A34 (ITT Cannon, LLC)

This part is the primary substitute for applications requiring active product status and RoHS compliance. The KPSE6E833P-DN-A34 maintains all critical electrical parameters including 3-position configuration, 8-33 shell size, crimp termination, bayonet lock fastening, and 7.5A current rating. The operating temperature range of -55°C to 125°C is reduced compared to the original MS3475L8-33P (-55°C to 200°C), making this substitute suitable for applications not requiring extended high-temperature operation. The part includes coupling nut and shrink boot adapter features and provides IP67 ingress protection. RoHS compliance status makes this option suitable for regulated procurement environments.

PV76L8-33PL (ITT Cannon, LLC)

This substitute is a plug housing component designed for male pins, maintaining the 3-position, 8-33 shell size, and bayonet lock configuration. The PV76L8-33PL operates across the full temperature range of -55°C to 200°C, matching the original part's thermal capability. This housing component is supplied without contacts and requires separate contact procurement. The electroless nickel shell finish and plastic insert material provide environmental resistance. This option is suitable for applications where housing replacement or upgrade is required.

PV76W8-33PL (ITT Cannon, LLC)

This substitute is functionally equivalent to the PV76L8-33PL but features a chromate over cadmium shell finish and olive drab housing color. The PV76W8-33PL maintains the same 3-position, 8-33 shell size, bayonet lock fastening, and full -55°C to 200°C operating temperature range. Like the PV76L8-33PL, this housing component is supplied without contacts. This option is suitable for military applications requiring specific finish and color specifications.

Frequently Asked Questions (FAQ)

Q: Can the KPSE6E833P-DN-A34 be used as a direct replacement for the MS3475L8-33P in all applications?

A: The KPSE6E833P-DN-A34 is electrically and mechanically compatible for applications operating within -55°C to 125°C. Applications requiring operation above 125°C must use PV76L8-33PL or PV76W8-33PL housings. The KPSE6E833P-DN-A34 is unshielded, whereas the MS3475L8-33P is shielded; applications requiring shielding must evaluate electromagnetic compatibility requirements independently.

Q: What is the difference between the PV76L8-33PL and PV76W8-33PL?

A: Both parts are plug housings with identical electrical and mechanical specifications. The primary differences are shell finish and color: PV76L8-33PL features electroless nickel finish with silver color, while PV76W8-33PL features chromate over cadmium finish with olive drab color. Selection depends on application-specific finish and color requirements.

Q: Why are the PV76 series parts supplied without contacts?

A: The PV76L8-33PL and PV76W8-33PL are plug housing components only. Contacts must be procured separately and crimped into the housing. This modular approach allows flexibility in contact material and finish selection based on specific application requirements.

Q: Does the KPSE6E833P-DN-A34 include the coupling nut and shrink boot adapter?

A: Yes, the KPSE6E833P-DN-A34 includes both coupling nut and shrink boot adapter features as standard components.

Q: Are all substitute parts rated for the same current capacity?

A: Yes, all substitute parts listed maintain the 7.5A current rating of the original MS3475L8-33P.

Q: What is the significance of RoHS compliance for the KPSE6E833P-DN-A34?

A: RoHS compliance indicates the part meets Restriction of Hazardous Substances regulations, restricting lead, cadmium, mercury, and other hazardous materials. This status is required for procurement in regulated industries and markets with environmental compliance mandates.

Q: Can the MS3475L8-33P be used interchangeably with substitute parts in existing assemblies?

A: Yes, all substitute parts maintain mechanical compatibility through identical shell size (8-33), bayonet lock fastening, and mounting configuration. Electrical compatibility is confirmed through matching current rating (7.5A), contact material (copper alloy), and contact finish (gold). Physical installation and mating are functionally equivalent.
