Engineering Selection Recommendations

All substitute diodes—AG01AV1, AU01AV0, and AU02AV1—are listed as Active products and RoHS Compliant. The primary diode, 1N4723, is RoHS non-compliant. For applications requiring RoHS compliance or adhering to similar regulatory standards, any substitute may be considered based on this parameter. Product status for all listed devices is Active, indicating suitability for ongoing designs and inventory fulfillment.

Frequently Asked Questions (FAQ)

Q1: What are the essential criteria for substituting the 1N4723 diode in my application?
A1: Substitution is strictly determined by matching voltage – DC reverse (Vr), package/case type (Axial), mounting type (Through Hole), and product status. Differences in current rating must be evaluated in the context of the application's exact electrical requirements.

Q2: Are substitute diodes directly compatible with the 1N4723 package and mounting?
A2: All substitutes are supplied in axial packages for through hole mounting, matching the mechanical requirements of the 1N4723.

Q3: Does the RoHS status affect part selection for new designs?
A3: Applications subject to RoHS compliance should select substitutes with RoHS Compliant status, as the 1N4723 is RoHS non-compliant.

Q4: How does current rating influence substitution?
A4: The 1N4723 is specified for 3A average rectified current; substitutes are rated lower (500mA or 800mA). Selection must match application needs and should not exceed the listed ratings.

Q5: What should be considered regarding operating temperature?
A5: The 1N4723 is rated for -65°C to +175°C junction temperatures; substitutes are rated for -40°C to +150°C. Verify that this range meets environmental and system requirements.
