Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICS9LPR502SGLFT is determined by strict equivalence across the following critical parameters:

• Frequency Synthesis Capability: Maximum output frequency of 400MHz with 1:19 input-to-output ratio
• Differential Signal Support: No/Yes differential input and output configuration
• Supply Voltage Range: 3.135V ~ 3.465V operating range
• Package Compatibility: 56-TFSOP (56-TSSOP) surface mount package with 0.240" (6.10mm) width
• Operating Temperature Range: 0°C ~ 70°C
• PLL Integration: Integrated Phase-Locked Loop functionality
• Application Domain: Intel CK505 and PCI Express (PCIe) clock generation

The substitute part 9LPRS525AGLFT meets all these parameters and is manufactured by the same supplier, Renesas Electronics Corporation.

Frequently Asked Questions (FAQ)

Q: Can the 9LPRS525AGLFT be used as a direct replacement for the ICS9LPR502SGLFT in existing designs?

A: Yes. The 9LPRS525AGLFT is electrically and mechanically equivalent across all specified parameters. Both parts feature identical 400MHz maximum frequency output, 1:19 input-to-output ratio, 56-TSSOP package configuration, and 3.135V ~ 3.465V supply voltage range. No circuit modifications are required.

Q: What is the significance of the product status difference between the two parts?

A: The ICS9LPR502SGLFT is classified as obsolete, indicating discontinued production and limited future availability. The 9LPRS525AGLFT maintains active production status, ensuring continued supply and support for new designs and legacy system maintenance.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 56-TFSOP (56-TSSOP) surface mount package with identical 0.240" (6.10mm) width dimensions. Pinout and footprint compatibility are maintained.

Q: Does the ROHS3 compliance of the 9LPRS525AGLFT affect compatibility?

A: No. ROHS3 compliance indicates adherence to hazardous substance restrictions and represents an improvement over the original part. The electrical and functional characteristics remain unchanged.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in frequency synthesis capability (400MHz, 1:19 ratio), differential signal configuration (No/Yes), supply voltage range (3.135V ~ 3.465V), operating temperature (0°C ~ 70°C), package type (56-TSSOP), and PLL integration. All these parameters are identical between the ICS9LPR502SGLFT and 9LPRS525AGLFT.
