Substitute Part Grouping Explanation

Substitution of the 8523CGILF is determined by functional equivalence within the Clock/Timing IC category. The primary substitute identified is the 8SLVP1204ANLGI, manufactured by Renesas Electronics Corporation. This substitution is based on the following criteria:

• Both components are manufactured by Renesas Electronics Corporation, ensuring design continuity and supply chain alignment
• Both are classified within the Clock/Timing category
• The substitute part (8SLVP1204ANLGI) maintains active product status, providing long-term availability
• Compliance certifications (ECCN: EAR99, HTSUS: 8542.39.0001) are identical, ensuring regulatory and trade classification compatibility
• The substitute operates within standard industrial temperature ranges and supply voltage specifications typical of clock management and distribution applications

Parameter Comparison

Engineering Selection Recommendations

Selection between the 8523CGILF and 8SLVP1204ANLGI should be based on the following engineering considerations:

The 8523CGILF, while currently in stock with 985 units available, carries Obsolete product status. This designation indicates that the manufacturer has discontinued active production and support. The 8SLVP1204ANLGI is classified as Active, ensuring ongoing manufacturer support, continued availability, and compliance with current manufacturing standards.

Both components share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, confirming regulatory and trade compliance equivalence. The substitute part maintains ROHS3 compliance, aligning with current environmental and manufacturing directives.

The 8SLVP1204ANLGI features a higher Moisture Sensitivity Level (MSL 3 versus MSL 1), which requires adherence to specific storage and handling protocols during the 168-hour window prior to soldering. This represents a more stringent handling requirement compared to the original part's unlimited MSL rating.

For new designs and long-term system support, the 8SLVP1204ANLGI is the appropriate selection due to its Active status and superior inventory availability (3800 units). For legacy system maintenance where the original part specification is critical, the 8523CGILF remains available from current stock.

Frequently Asked Questions (FAQ)

Q: Why is the 8523CGILF listed as Obsolete?

A: Obsolete status indicates that Renesas Electronics Corporation has discontinued active production and support for this component. Manufacturers typically obsolete parts when they are replaced by newer designs or when demand no longer justifies continued manufacturing.

Q: Can the 8SLVP1204ANLGI directly replace the 8523CGILF in existing applications?

A: Both components are Clock/Timing ICs manufactured by Renesas Electronics Corporation and share identical regulatory classifications. However, direct replacement requires verification that the specific functional characteristics, pinout, and electrical specifications of the 8SLVP1204ANLGI align with the original application requirements. The detailed specifications of the original 8523CGILF should be consulted to confirm compatibility.

Q: What is the significance of the different Moisture Sensitivity Levels?

A: The 8523CGILF has MSL 1 (Unlimited), meaning it can be stored indefinitely without moisture absorption concerns. The 8SLVP1204ANLGI has MSL 3 (168 Hours), requiring that the component be soldered within 168 hours of exposure to ambient humidity conditions. This necessitates more rigorous moisture control during storage and handling.

Q: Are there additional substitute options beyond the 8SLVP1204ANLGI?

A: The 8SLVP1204ANLGI is identified as the primary Renesas-recommended substitute. The 8SLVP1204ANLGI itself lists secondary substitutes (CDCLVP1204RGTR, CDCLVP1204RGTT), which may be evaluated for extended compatibility options within the broader clock distribution IC family.

Q: What is the inventory status for these components?

A: The 8523CGILF has 985 units of new original stock currently available. The 8SLVP1204ANLGI has 3800 units of new original stock available, providing significantly greater supply security for ongoing procurement.
