Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFD57-22-55SN are selected based on strict alignment with the following critical parameters:

Core Compatibility Parameters:

• 55-position configuration
• Shell size 22-55
• Free hanging (in-line) mounting
• Bayonet lock fastening
• Crimp contact type
• Operating temperature range -55°C ~ 200°C
• Aluminum alloy shell material
• Environment resistant ingress protection

The substitute parts listed are ITT Cannon, LLC PV series connector housings. These components share the same position count, shell size, mounting configuration, and fastening mechanism as the original AFD57-22-55SN. Substitutes differ in shell finish (electroless nickel, chromate over cadmium, or anodized) and shielding characteristics (shielded or unshielded). The PV75L22-55SL and PV75W22-55SL variants maintain shielded configurations, while PV76L22-55SL, PV76W22-55SL, and PV76A22-55SL provide unshielded alternatives.

Parameter Comparison

Engineering Selection Recommendations

For Shielded Applications:

Select PV75L22-55SL or PV75W22-55SL when electromagnetic shielding is required. Both maintain shielded configurations equivalent to the original AFD57-22-55SN. PV75L22-55SL features electroless nickel finish with silver housing color. PV75W22-55SL provides chromate over cadmium finish with olive drab housing color. Both are active products with full inventory availability.

For Unshielded Applications:

Select PV76L22-55SL, PV76W22-55SL, or PV76A22-55SL when shielding is not required. PV76L22-55SL offers electroless nickel finish. PV76W22-55SL provides chromate over cadmium finish. PV76A22-55SL features anodized finish. All three are active products with established supply chains.

Compliance Considerations:

All substitute parts maintain identical RoHS non-compliance status and MSL rating (1 - Unlimited) as the original AFD57-22-55SN. All substitute parts are active products, eliminating obsolescence risk associated with the discontinued AFD57-22-55SN.

Note on Connector Type:

The AFD57-22-55SN is specified as a complete plug with female sockets and crimp termination. The substitute parts are listed as plug housings. Verification of contact compatibility and assembly requirements is necessary during component procurement.

Frequently Asked Questions (FAQ)

Q: Can PV76 series (unshielded) parts directly replace the shielded AFD57-22-55SN?

A: Direct substitution depends on application requirements. The PV76 series maintains all mechanical and electrical parameters except shielding. If electromagnetic interference protection is required, unshielded variants are not suitable. If shielding is not a functional requirement, PV76 series parts provide equivalent mechanical and thermal performance.

Q: What is the difference between PV75L22-55SL and PV75W22-55SL?

A: Both are shielded 55-position connectors with identical mechanical specifications. The primary difference is shell finish: PV75L22-55SL uses electroless nickel with silver housing, while PV75W22-55SL uses chromate over cadmium with olive drab housing. Selection depends on corrosion resistance requirements and environmental exposure conditions.

Q: Are the ITT Cannon PV series housings compatible with the original AFD57-22-55SN contacts?

A: The substitute parts are specified as plug housings with contact size 20. Compatibility with existing contacts requires verification of contact specifications and insertion force parameters. Contact the component supplier for detailed compatibility matrices.

Q: Why are the substitute parts listed as "Plug Housing" rather than complete plugs?

A: The substitute parts are connector housings supplied without pre-installed contacts. This configuration allows for custom contact selection and assembly. The AFD57-22-55SN is specified as a complete plug with female sockets. Procurement of compatible contacts is required when using substitute housings.

Q: Do all substitute parts support the same operating temperature range?

A: Yes. All substitute parts (PV75L22-55SL, PV75W22-55SL, PV76L22-55SL, PV76W22-55SL, PV76A22-55SL) support the identical operating temperature range of -55°C to 200°C as the original AFD57-22-55SN.

Q: What is the inventory status of substitute parts?

A: All substitute parts are active products with current inventory: PV75L22-55SL (1078 pcs), PV75W22-55SL (749 pcs), PV76L22-55SL (887 pcs), PV76W22-55SL (676 pcs), and PV76A22-55SL (843 pcs). Availability exceeds the original AFD57-22-55SN (779 pcs, discontinued).

Q: Are there differences in environmental resistance between substitute options?

A: All substitute parts maintain environment resistant ingress protection equivalent to the original AFD57-22-55SN. Shell finish variations (electroless nickel, chromate over cadmium, anodized) provide different corrosion resistance profiles suitable for specific environmental exposures.
