Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ALD1721EPAL are determined strictly based on the following parameters: amplifier category (Linear, Amplifiers), number of circuits, output type (rail-to-rail), package type (8-DIP, 7.62mm through-hole), RoHS and REACH compliance, operating temperature, and mounting type. Only parts matching these core electrical, mechanical, and compliance parameters are considered as valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection between ALD1721EPAL and AD623BNZ should be based on product status and compliance information. ALD1721EPAL is marked as "Not For New Designs," while AD623BNZ is "Active." Both meet ROHS3 and REACH compliance and offer MSL 1 (unlimited). For ongoing supply assurance, the use of the active part number (AD623BNZ) is technically preferable where compliance and inventory are required.

Frequently Asked Questions (FAQ)

Q: What are the key criteria for substituting ALD1721EPAL in linear amplifier applications?
A: Substitution is based on amplifier category, number of circuits, output type (rail-to-rail), through-hole mounting, identical package (8-DIP, 0.300" / 7.62mm), and RoHS/REACH compliance.

Q: Is the package and pinout compatible between ALD1721EPAL and AD623BNZ?
A: Both parts use the 8-DIP (0.300", 7.62mm) and 8-PDIP through-hole package, supporting compatibility in socket and PCB mount applications.

Q: How does the product status affect substitute selection?
A: ALD1721EPAL’s “Not For New Designs” status means it is not recommended for new projects. AD623BNZ is in active production, ensuring better long-term supply.

Q: Are both ALD1721EPAL and AD623BNZ compliant with environmental regulations?
A: Yes, both are ROHS3 compliant, REACH unaffected, and have MSL level 1 (unlimited), meeting current regulatory and industry standards.
