Engineering Selection Recommendations

The SP723APP is the direct substitute for the SP723AP. Both parts share identical electrical specifications and mechanical form factors, ensuring pin-compatible replacement in existing circuit designs.

The SP723APP offers significant advantages for new procurement:

  • Active Product Status: The SP723APP maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete SP723AP.
  • Regulatory Compliance: The SP723APP meets ROHS3 compliance requirements, whereas the SP723AP is RoHS non-compliant. This distinction is critical for applications subject to environmental regulations.
  • REACH Compliance: The SP723APP carries REACH Unaffected status, providing additional regulatory assurance for European market applications.

For legacy system maintenance where the SP723AP is currently deployed, the SP723APP provides a direct replacement path without requiring circuit redesign or PCB modifications.

Frequently Asked Questions (FAQ)

Q: Can the SP723APP directly replace the SP723AP in existing designs?

A: Yes. The SP723APP is a pin-compatible, form-factor equivalent substitute. Both devices feature identical 8-DIP packaging, 6-circuit configuration, and mixed-technology TVS architecture. No circuit modifications are required.

Q: What is the primary reason to transition from SP723AP to SP723APP?

A: The SP723AP is classified as obsolete, creating procurement and supply chain risk. The SP723APP is an active product with confirmed long-term availability. Additionally, the SP723APP meets ROHS3 and REACH compliance standards, whereas the SP723AP does not.

Q: Are there any electrical performance differences between these parts?

A: No electrical performance differences are specified in the available technical parameters. Both devices are rated for general-purpose TVS applications with identical circuit counts and package specifications.

Q: What packaging options are available?

A: The SP723AP packaging specification is not detailed in available documentation. The SP723APP is supplied in tube packaging, which is standard for through-hole DIP components.

Q: Does the SP723APP require different handling or storage procedures?

A: Both parts share identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: Are there compliance considerations for my application?

A: If your application operates in regulated markets or requires RoHS/REACH compliance documentation, the SP723APP is the appropriate selection. The SP723AP's non-compliant status may create regulatory or procurement barriers.
