Substitute Part Grouping Explanation

Substitution eligibility for the 74ALVT16823DL,518 is determined by strict equivalence across the following critical parameters:

• Functional Architecture: Dual 9-bit D-type flip-flop with master reset and positive edge triggering
• Output Configuration: Tri-state, non-inverted outputs
• Electrical Performance: 250 MHz clock frequency, 3.1 ns maximum propagation delay at 3.3V with 50 pF load
• Supply Voltage Compatibility: 2.3V ~ 2.7V and 3V ~ 3.6V operating ranges
• Thermal Range: -40°C ~ 85°C operating temperature
• Compliance Standards: ROHS3 compliance and MSL 2 rating
• Manufacturer: Nexperia USA Inc.
• Base Product Number: 74ALVT16823

The 74ALVT16823DGGY qualifies as a direct substitute based on identical functional specifications, electrical characteristics, and compliance certifications. The primary distinction lies in packaging format and supplier delivery method.

Parameter Comparison

Engineering Selection Recommendations

Both the 74ALVT16823DL,518 and 74ALVT16823DGGY are classified as obsolete products. Selection between these parts should be based on the following criteria:

Package Compatibility: The primary difference is the package format. The 74ALVT16823DL,518 uses 56-BSSOP (0.295", 7.50 mm width), while the 74ALVT16823DGGY uses 56-TFSOP (0.240", 6.10 mm width). PCB layout and footprint requirements will determine which package is suitable for your application.

Supplier Delivery Format: The 74ALVT16823DGGY is available in Cut Tape (CT) and Digi-Reel® packaging, which may affect procurement logistics and handling procedures.

Compliance and Certification: Both parts maintain identical ROHS3 compliance, REACH unaffected status, and EAR99 export classification, ensuring regulatory equivalence for applications requiring these certifications.

Electrical and Functional Equivalence: All electrical parameters, timing specifications, and functional characteristics are identical, confirming direct substitutability from a circuit design perspective.

Frequently Asked Questions (FAQ)

Q: Can the 74ALVT16823DGGY directly replace the 74ALVT16823DL,518 in my circuit?

A: Yes, from an electrical and functional standpoint. Both parts are identical in all performance parameters, supply voltage ranges, operating temperature, and output specifications. The substitution is valid provided the PCB footprint accommodates the 56-TFSOP package format of the DGGY variant.

Q: What is the key difference between these two part numbers?

A: The primary difference is the package format. The DL,518 uses 56-BSSOP with a 7.50 mm width, while the DGGY uses 56-TFSOP with a 6.10 mm width. Both are surface-mount packages with identical pin configurations and electrical characteristics.

Q: Are there any timing or performance differences between these parts?

A: No. Both parts have identical clock frequency (250 MHz), propagation delay (3.1 ns @ 3.3V, 50 pF), quiescent current (100 µA), and all other electrical specifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 74ALVT16823DL,518 and 74ALVT16823DGGY are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Both carry MSL 2 (1 Year) moisture sensitivity ratings.

Q: Why are these parts listed as obsolete?

A: Both parts are classified as obsolete by the manufacturer. This status indicates that production has been discontinued. Existing inventory may be available through authorized distributors, but long-term availability cannot be guaranteed.

Q: What should I consider when selecting between these two packages?

A: Evaluate your PCB layout constraints and available board space. The 56-TFSOP package (DGGY) is narrower (6.10 mm vs. 7.50 mm), which may be advantageous for space-constrained designs. Verify that your PCB footprint library supports the selected package format before finalizing the design.
