AFD50-12-3SN Equivalent & Substitute Parts

Part Overview

The AFD50-12-3SN is a 3-position circular connector receptacle manufactured by TE Connectivity Deutsch Connectors, designed for panel mount applications with bayonet lock fastening. This connector features female sockets with crimp termination, gold-plated mating contacts, and an aluminum shell with nickel finish. The part is rated for 13A current and operates across a temperature range of -55°C to 200°C, making it suitable for aviation, automotive, and military applications.

The AFD50-12-3SN is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design compatibility and ensure continued availability for production, repair, and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AFD50-12-3SN is based on strict alignment of the following critical parameters:

Mechanical Compatibility:

• 3-position connector configuration
• Shell size 12-3 insert designation
• Panel mount with flange mounting feature
• Bayonet lock fastening mechanism
• Normal (N) orientation

Electrical Compatibility:

• Receptacle housing for female sockets
• Crimp contact termination
• 13A current rating capability
• Operating temperature range -55°C to 200°C
• Environment resistant ingress protection

Material & Finish Specifications:

• Aluminum shell construction
• Gold or equivalent mating contact finish
• Plastic insert material

The substitute part PV70W12-3SL meets these critical parameters and is classified as a direct functional equivalent for the AFD50-12-3SN.

Parameter Comparison

Engineering Selection Recommendations

AFD50-12-3SN (Main Part): The AFD50-12-3SN remains available through existing inventory channels with 607 pieces in stock. This part is suitable for applications where existing design specifications explicitly reference the TE Connectivity Deutsch Connectors AFD series. However, the discontinued status at DiGi Electronics indicates limited future availability through standard distribution channels.

PV70W12-3SL (Substitute): The PV70W12-3SL is the recommended substitute for new designs and ongoing production requirements. This ITT Cannon connector maintains active product status with 906 pieces in inventory, ensuring sustained availability. The PV70W12-3SL meets all critical mechanical, electrical, and environmental specifications of the AFD50-12-3SN. Both parts are RoHS non-compliant and carry identical ECCN classification (EAR99), maintaining compliance consistency for export and regulatory purposes.

The primary difference is the shell finish specification: the AFD50-12-3SN uses nickel finish while the PV70W12-3SL uses chromate over cadmium finish. Both finishes provide equivalent corrosion resistance and environmental protection for the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the PV70W12-3SL directly replace the AFD50-12-3SN in existing assemblies?

A: Yes. Both connectors share identical shell size (12-3), position count (3), mounting configuration (panel mount flange), fastening mechanism (bayonet lock), and operating temperature range (-55°C to 200°C). The crimp termination and female socket receptacle configuration are functionally equivalent.

Q: What is the difference between the shell finishes?

A: The AFD50-12-3SN features a nickel shell finish, while the PV70W12-3SL uses chromate over cadmium finish. Both finishes provide environment-resistant protection and are suitable for aviation, automotive, and military applications across the specified temperature range.

Q: Does the PV70W12-3SL include contacts?

A: No. The PV70W12-3SL is supplied as a receptacle housing only, with contacts not included. Contacts must be sourced separately and crimped according to the connector specifications. The AFD50-12-3SN similarly requires separate contact procurement for crimp assembly.

Q: Are both parts RoHS compliant?

A: No. Both the AFD50-12-3SN and PV70W12-3SL are RoHS non-compliant. This status is consistent across both parts and does not affect substitution compatibility.

Q: What is the current rating for these connectors?

A: The AFD50-12-3SN is rated for 13A. The PV70W12-3SL specifications provided do not explicitly state a current rating; however, the identical shell size, contact type, and crimp termination indicate equivalent current-carrying capacity for the 3-position configuration.

Q: Can these connectors be used interchangeably with different shell sizes?

A: No. Both connectors are specifically designated for shell size 12-3. Connectors with different shell sizes (such as 12-2 or 12-4) are not interchangeable and will not mate correctly.

Q: What is the contact size for the PV70W12-3SL?

A: The PV70W12-3SL uses contact size 16. This specification is provided for contact procurement and crimping tool selection.
