Key Parameters

Substitute Part Grouping Explanation

Substitution of the AFD50-20-41SN is determined by strict alignment of the following critical parameters:

Position and Mechanical Compatibility:

• 41-position connector configuration
• Shell size 20-41 insert specification
• Panel mount with flange mounting feature
• Bayonet lock fastening mechanism
• Normal (N) orientation

Electrical and Environmental Performance:

• Crimp termination method
• Operating temperature range -55°C to 200°C
• Environment-resistant ingress protection
• 7.5A current rating capability

Material and Compliance:

• Aluminum shell construction
• Plastic insert material
• RoHS non-compliant status
• MSL 1 (Unlimited) moisture sensitivity

The substitute part PV70W20-41SL meets all critical mechanical and electrical parameters required for functional equivalence with the AFD50-20-41SN.

Parameter Comparison

Engineering Selection Recommendations

AFD50-20-41SN (Primary Part - Discontinued): The AFD50-20-41SN remains the original specification component. However, this part is discontinued at DiGi Electronics, limiting future procurement options. Existing inventory of 1010 pieces is available through current stock channels.

PV70W20-41SL (Active Substitute): The PV70W20-41SL is the recommended substitute for new designs and ongoing production requirements. This part maintains active product status with 962 pieces in current inventory. The PV70W20-41SL satisfies all critical mechanical, electrical, and environmental parameters required for functional equivalence. Both components share identical operating temperature ranges, position counts, shell sizes, mounting configurations, and fastening mechanisms.

Compliance Considerations: Both the AFD50-20-41SN and PV70W20-41SL carry RoHS non-compliant status and are classified under ECCN EAR99. Applications requiring RoHS compliance require alternative component selection outside this substitution group.

Availability and Supply Chain: Selection between these parts should prioritize the PV70W20-41SL for new procurement due to active product status and ongoing manufacturer support. The AFD50-20-41SN should be reserved for legacy system maintenance where original specification compliance is mandatory.

Frequently Asked Questions (FAQ)

Q: Can the PV70W20-41SL directly replace the AFD50-20-41SN in existing assemblies?

A: Yes. Both connectors share identical 41-position configuration, shell size 20-41, panel mount flange design, bayonet lock fastening, and operating temperature range of -55°C to 200°C. Mechanical and electrical compatibility is established through these matching parameters.

Q: What is the significance of the "Contacts Not Included" note on the PV70W20-41SL?

A: The PV70W20-41SL is supplied as a receptacle housing assembly without pre-installed crimp contacts. The AFD50-20-41SN specification does not explicitly state contact inclusion status. Verify contact compatibility and procurement requirements separately when selecting the PV70W20-41SL.

Q: Are there differences in shell finish between these two parts?

A: Yes. The AFD50-20-41SN features nickel shell finish with gold mating contact finish. The PV70W20-41SL features chromate over cadmium shell finish with olive drab housing color. Both finishes provide environment-resistant protection suitable for aviation, automotive, and military applications. Material compatibility with mating components should be confirmed for specific installations.

Q: Why is the AFD50-20-41SN discontinued?

A: The AFD50-20-41SN is discontinued at DiGi Electronics. Manufacturer discontinuation decisions are based on market demand, product line consolidation, and supply chain factors. The PV70W20-41SL remains in active production as a functionally equivalent alternative.

Q: Do both parts meet the same environmental and compliance standards?

A: Both parts are RoHS non-compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are classified as ECCN EAR99. Both provide environment-resistant ingress protection and operate across the identical temperature range of -55°C to 200°C. Applications with specific compliance requirements should verify regulatory applicability for each part independently.

Q: What is the difference between the AFD and PV series designations?

A: AFD50-20-41SN belongs to the TE Connectivity Deutsch Connectors MIL-DTL-26482 G Series II AFD product line. PV70W20-41SL belongs to the ITT Cannon PV series product line. Both series are designed for circular connector applications in military and industrial environments. Series designation reflects manufacturer product architecture and does not affect functional substitution eligibility when critical parameters align.
