Key Parameters

Substitute Part Grouping Explanation

Substitution of the AFD56-18-32SN is determined by strict alignment of the following critical parameters:

Core Compatibility Parameters:

• Number of Positions: 32
• Shell Size - Insert: 18-32
• Connector Type: Plug Housing for Female Sockets
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Orientation: N (Normal)
• Termination: Crimp
• Operating Temperature Range: -55°C ~ 200°C
• Ingress Protection: Environment Resistant

Substitute Part Characteristics:

All four substitute parts (PV75L18-32SL, PV75W18-32SL, PV76L18-32SL, PV76W18-32SL) are manufactured by ITT Cannon, LLC and meet the core compatibility parameters listed above. These parts are classified as plug housings with coupling nuts, designed for female socket integration. The substitutes differ in two secondary parameters:

1. Shell Finish: Electroless Nickel (L-series) or Chromate over Cadmium (W-series)
2. Shielding Configuration: Shielded (PV75 series) or Unshielded (PV76 series)

All substitute parts maintain active product status and are available in bulk packaging with current inventory levels exceeding 900 units per part number.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The AFD56-18-32SN is discontinued, requiring substitution with active product alternatives. All four ITT Cannon substitute parts maintain functional equivalence across core electrical and mechanical parameters. Selection between substitute options is determined by application-specific requirements for shell finish and electromagnetic shielding.

Shielding Consideration:

Applications requiring electromagnetic interference mitigation should specify PV75L18-32SL or PV75W18-32SL (shielded variants). Applications without shielding requirements may utilize PV76L18-32SL or PV76W18-32SL (unshielded variants).

Shell Finish Selection:

Electroless Nickel finish (L-series: PV75L18-32SL, PV76L18-32SL) provides corrosion resistance suitable for general industrial and aerospace environments. Chromate over Cadmium finish (W-series: PV75W18-32SL, PV76W18-32SL) offers enhanced corrosion protection for military and harsh environmental applications.

Compliance Status:

All substitute parts maintain RoHS non-compliant status consistent with the original AFD56-18-32SN, ensuring regulatory alignment for legacy system applications. All parts carry ECCN EAR99 classification and are available in bulk packaging with current inventory levels supporting immediate procurement.

Frequently Asked Questions (FAQ)

Q: Can PV75L18-32SL, PV75W18-32SL, PV76L18-32SL, or PV76W18-32SL directly replace AFD56-18-32SN in existing assemblies?

A: All four substitute parts are mechanically and electrically compatible with the AFD56-18-32SN. They share identical position count (32), shell size (18-32), mounting configuration (free hanging in-line), fastening method (bayonet lock), and operating temperature range (-55°C to 200°C). The substitute parts are plug housings designed for female socket integration, maintaining functional equivalence with the original connector.

Q: What is the difference between shielded (PV75 series) and unshielded (PV76 series) variants?

A: The PV75 series (PV75L18-32SL and PV75W18-32SL) incorporates shielding for electromagnetic interference protection. The PV76 series (PV76L18-32SL and PV76W18-32SL) does not include shielding. Selection depends on whether the application requires EMI mitigation. Both configurations maintain identical mechanical compatibility and operating specifications.

Q: What is the difference between Electroless Nickel (L-series) and Chromate over Cadmium (W-series) finishes?

A: Electroless Nickel finish (L-series) provides standard corrosion resistance for general industrial, automotive, and aerospace applications. Chromate over Cadmium finish (W-series) offers enhanced corrosion protection and is specified for military applications and harsh environmental exposure. Both finishes maintain equivalent electrical performance and mechanical compatibility.

Q: Are the substitute parts available in the same quantities as the original AFD56-18-32SN?

A: The substitute parts are available in greater quantities than the discontinued AFD56-18-32SN. Current inventory levels are: PV75L18-32SL (1,073 units), PV75W18-32SL (995 units), PV76L18-32SL (920 units), and PV76W18-32SL (1,018 units), all in bulk packaging. The original AFD56-18-32SN has 844 units in stock but is discontinued.

Q: Do the substitute parts include contacts?

A: The substitute parts are plug housings supplied without contacts. The note "Contacts Not Included" applies to all four ITT Cannon alternatives. Contacts must be procured separately and crimped according to connector specifications.

Q: Are all substitute parts RoHS compliant?

A: No. All substitute parts maintain RoHS non-compliant status consistent with the original AFD56-18-32SN. This alignment ensures regulatory consistency for legacy system applications and military specifications that do not require RoHS compliance.

Q: What is the moisture sensitivity level for these connectors?

A: All parts, including the original AFD56-18-32SN and all four substitute options, carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Which substitute part should be selected for military applications?

A: For military applications, PV75W18-32SL or PV76W18-32SL are recommended based on the Chromate over Cadmium finish, which provides enhanced corrosion protection specified for military environments. Selection between shielded (PV75W18-32SL) and unshielded (PV76W18-32SL) depends on electromagnetic interference requirements.
