Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFD57-14-19PN is determined by the following critical parameters:

Core Compatibility Requirements:

• 19-position connector configuration
• Shell size 14-19 (MIL-DTL-26482 Series II compatible)
• Crimp termination method
• Bayonet lock fastening mechanism
• Free hanging (in-line) mounting type
• Normal (N) orientation
• Aluminum shell material
• Gold contact finish (mating surface)
• Environment resistant ingress protection
• Shielded configuration

Substitute Categories:

Category 1: Direct Equivalent (Complete Connector Assembly) MS3476A14-19P from Amphenol Aerospace Operations is a direct equivalent. This part maintains all core compatibility parameters including the shielded configuration, gold contact finish, and bayonet lock fastening. The primary difference is the shell finish (black anodized versus nickel) and extended operating temperature range (-65°C to 200°C versus -55°C to 200°C).

Category 2: Plug Housing Substitutes (Contacts Not Included) PV75L14-19PL, PV75W14-19PL, PV76L14-19PL, and PV76W14-19PL from ITT Cannon, LLC are plug housing components designed for male pins. These parts share the 19-position, 14-19 shell size, crimp contact type, bayonet lock fastening, and free hanging mounting configuration. Key distinctions include:

• These are housing-only components; contacts are not included
• PV75L14-19PL and PV75W14-19PL maintain shielded configuration
• PV76L14-19PL and PV76W14-19PL are unshielded variants
• Shell finish options include electroless nickel and chromate over cadmium
• Housing colors vary (silver or olive drab)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Complete Assembly):

MS3476A14-19P from Amphenol Aerospace Operations is the primary equivalent for the AFD57-14-19PN. This part is currently active in production and maintains all critical electrical and mechanical parameters. The MS3476A14-19P is qualified to MIL-DTL-26482 Series II, matching the original specification. The extended operating temperature range (-65°C to 200°C) provides additional thermal margin compared to the original part. Both parts are RoHS non-compliant and carry the same ECCN and HTSUS classifications, indicating equivalent regulatory status.

For Housing-Only Applications:

When only the connector housing is required (with separate contact procurement), the PV75L14-19PL and PV75W14-19PL maintain the shielded configuration of the original AFD57-14-19PN. These ITT Cannon parts are active products with established supply chains. The PV75L14-19PL features electroless nickel finish (silver color), while PV75W14-19PL uses chromate over cadmium finish (olive drab color). Both support the same operating temperature range and crimp contact configuration.

For Unshielded Applications:

PV76L14-19PL and PV76W14-19PL are unshielded housing variants from ITT Cannon. These parts are suitable only when shielding is not required by the application. The unshielded configuration reduces electromagnetic interference protection compared to the original shielded AFD57-14-19PN.

Compliance Considerations:

All substitute parts listed are RoHS non-compliant, consistent with the original AFD57-14-19PN. All parts carry EAR99 ECCN classification and are suitable for the same regulatory environments. The MIL-DTL-26482 Series II qualification is maintained across all direct equivalents and housing variants.

Frequently Asked Questions (FAQ)

Q: Can MS3476A14-19P be used as a direct replacement for AFD57-14-19PN?

A: Yes. MS3476A14-19P is a direct equivalent. Both parts are 19-position connectors with 14-19 shell size, crimp termination, bayonet lock fastening, and shielded configuration. The MS3476A14-19P is currently in active production, whereas the AFD57-14-19PN is discontinued. The primary difference is shell finish (black anodized versus nickel) and operating temperature range (-65°C to 200°C versus -55°C to 200°C).

Q: What is the difference between the PV75 and PV76 series housing parts?

A: The primary difference is shielding. PV75L14-19PL and PV75W14-19PL are shielded variants, matching the shielded configuration of the original AFD57-14-19PN. PV76L14-19PL and PV76W14-19PL are unshielded variants. Within each series, the "L" designation indicates electroless nickel finish (silver), while "W" indicates chromate over cadmium finish (olive drab).

Q: Are the ITT Cannon housing parts complete connector assemblies?

A: No. PV75L14-19PL, PV75W14-19PL, PV76L14-19PL, and PV76W14-19PL are housing-only components. Contacts are not included and must be procured separately. These parts are suitable for applications where the housing requires replacement but existing contacts can be reused or new contacts are sourced independently.

Q: Can I use an unshielded housing (PV76 series) in place of the shielded AFD57-14-19PN?

A: Only if the application does not require electromagnetic shielding. The unshielded PV76 variants will not provide the same level of EMI protection as the original shielded AFD57-14-19PN. Application requirements must be evaluated before selecting an unshielded alternative.

Q: What is the operating temperature difference between AFD57-14-19PN and MS3476A14-19P?

A: AFD57-14-19PN operates from -55°C to 200°C, while MS3476A14-19P operates from -65°C to 200°C. MS3476A14-19P provides an additional 10°C of low-temperature capability. Both parts support the same maximum temperature of 200°C.

Q: Are all substitute parts RoHS compliant?

A: No. The AFD57-14-19PN and all listed substitute parts (MS3476A14-19P, PV75L14-19PL, PV75W14-19PL, PV76L14-19PL, PV76W14-19PL) are RoHS non-compliant. This is consistent across all alternatives.

Q: What is the current rating for MS3476A14-19P?

A: The current rating for MS3476A14-19P is not specified in the available technical data. The original AFD57-14-19PN is rated for 7.5A. Current rating specifications should be obtained directly from Amphenol Aerospace Operations for the MS3476A14-19P if this parameter is critical to the application.

Q: Can the PV75 and PV76 housing parts be used interchangeably?

A: PV75 and PV76 series housings are not interchangeable due to shielding differences. PV75 variants are shielded; PV76 variants are unshielded. Selection depends on whether electromagnetic shielding is required by the application. Within each series, "L" and "W" variants (differing in shell finish and color) are mechanically interchangeable but may have different environmental performance characteristics based on finish type.
