Key Parameters

Substitute Part Grouping Explanation

Substitution of the AFD57-12-8SN is based on the following critical parameters that must align across candidate parts:

Mandatory Matching Parameters:

• Number of Positions: 8
• Shell Size - Insert: 12-8
• Fastening Type: Bayonet Lock
• Mounting Type: Free Hanging (In-Line)
• Operating Temperature Range: -55°C ~ 200°C
• Termination Method: Crimp
• Ingress Protection: Environment Resistant

The substitute part PV76L12-8SL meets these core electrical and mechanical requirements. However, the substitute differs in shielding configuration (unshielded versus shielded) and does not include contacts, requiring separate procurement of compatible crimp contacts for complete assembly.

Parameter Comparison

Engineering Selection Recommendations

The PV76L12-8SL serves as a functional substitute for the discontinued AFD57-12-8SN based on matching core mechanical and electrical parameters: 8-position configuration, 12-8 shell size, bayonet lock fastening, free-hanging mounting, crimp termination, and identical operating temperature range.

Critical Considerations:

The PV76L12-8SL is supplied as a plug housing without integrated contacts. The AFD57-12-8SN includes female sockets. Substitution requires separate procurement and installation of compatible crimp contacts to achieve functional equivalence.

The PV76L12-8SL is unshielded, whereas the AFD57-12-8SN is shielded. Applications requiring electromagnetic shielding must evaluate whether unshielded operation is acceptable for the intended circuit environment.

Both parts share identical RoHS non-compliance status and MSL rating, ensuring consistency in supply chain compliance documentation.

The PV76L12-8SL maintains active product status, providing long-term availability and supply chain stability compared to the discontinued AFD57-12-8SN.

Frequently Asked Questions (FAQ)

Q: Can the PV76L12-8SL directly replace the AFD57-12-8SN in existing assemblies?

A: Direct replacement is not possible without additional procurement. The PV76L12-8SL is a plug housing supplied without contacts. The AFD57-12-8SN includes female sockets. Compatible crimp contacts must be sourced and installed separately to achieve functional equivalence.

Q: What is the impact of the shielding difference between these parts?

A: The AFD57-12-8SN is shielded; the PV76L12-8SL is unshielded. Shielding provides electromagnetic interference (EMI) protection. Applications operating in electromagnetically noisy environments or requiring EMI compliance must evaluate whether unshielded operation meets system requirements.

Q: Are the bayonet lock fastening mechanisms compatible between these parts?

A: Both parts use bayonet lock fastening and are mechanically compatible for mating operations. The fastening mechanism operates identically across both designs.

Q: Do both parts support the same operating temperature range?

A: Yes. Both the AFD57-12-8SN and PV76L12-8SL operate across -55°C to 200°C, ensuring thermal compatibility for equivalent applications.

Q: What contact size is required for the PV76L12-8SL?

A: The PV76L12-8SL accommodates contact size 20 crimp contacts. Contacts must be sourced separately and must be compatible with this specification.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS non-compliant and carry MSL rating 1 (Unlimited). Compliance profiles are identical, ensuring consistency in regulatory documentation and supply chain management.

Q: What is the inventory status for each part?

A: The AFD57-12-8SN is discontinued at DiGi Electronics. The PV76L12-8SL is active with 776 pieces in stock, providing reliable procurement availability.
