Key Parameters

Substitute Part Grouping Explanation

Substitution of the AFD56-20-39PN is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 39
• Shell Size - Insert: 20-39
• Connector Type: Plug configuration for male pins
• Termination Method: Crimp
• Fastening Type: Bayonet Lock
• Mounting Type: Free Hanging (In-Line)
• Operating Temperature Range: -55°C ~ 200°C
• Ingress Protection: Environment Resistant

The substitute parts PV75L20-39PL and PV76W20-39PL are classified as plug housings designed for male pins with identical position count, shell size, crimp contact type, bayonet fastening, and operating temperature specifications. Both substitute parts maintain the same mechanical interface and environmental protection rating as the original component.

Parameter Comparison

Engineering Selection Recommendations

AFD56-20-39PN Status: This component is discontinued at DiGi Electronics, making it unavailable for new procurement through standard distribution channels.

Substitute Selection Criteria:

Both PV75L20-39PL and PV76W20-39PL are active products manufactured by ITT Cannon, LLC and maintain full mechanical and electrical compatibility with the AFD56-20-39PN across all critical parameters. Both substitute parts satisfy the same 39-position, 20-39 shell size, crimp termination, and bayonet lock specifications.

Differentiation Between Substitutes:

PV75L20-39PL features electroless nickel shell finish with shielded configuration.

PV76W20-39PL features chromate over cadmium shell finish with unshielded configuration and olive drab housing color.

Selection between these two substitutes depends on application-specific requirements regarding shielding and environmental finish specifications. Both parts are RoHS non-compliant, consistent with the original component classification.

Frequently Asked Questions (FAQ)

Q: Can PV75L20-39PL and PV76W20-39PL be used interchangeably with AFD56-20-39PN?

A: Both substitute parts maintain identical mechanical interfaces, position counts, shell sizes, termination methods, and operating temperature ranges. The primary differences are shell finish material and shielding configuration. Selection depends on application-specific environmental and electromagnetic requirements.

Q: What is the difference between the two substitute parts?

A: PV75L20-39PL provides a shielded configuration with electroless nickel finish. PV76W20-39PL provides an unshielded configuration with chromate over cadmium finish and olive drab color. Both maintain identical crimp contact specifications and bayonet fastening.

Q: Are the substitute parts available in the same packaging as the original?

A: The AFD56-20-39PN packaging information is not specified in the original documentation. Both substitute parts are supplied in bulk packaging. Inventory availability: PV75L20-39PL (919 pcs), PV76W20-39PL (1060 pcs).

Q: Do the substitute parts require the same contact pins as the original?

A: The substitute parts are plug housings supplied without contacts included. Contact compatibility is determined by the crimp contact specifications: Contact Size 16 (2 positions) and Contact Size 20 (37 positions).

Q: Are there any compliance differences between the original and substitute parts?

A: All three parts are RoHS non-compliant and classified under ECCN EAR99. Both substitute parts maintain the same moisture sensitivity level (MSL 1 - Unlimited) as the original component.
