Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the 525-01RLF is based on the following critical parameters:

• Manufacturer: Renesas Electronics Corporation (same manufacturer ensures design continuity and support)
• Category: Clock/Timing (functional category match)
• Type: Clock Generator functionality
• PLL Capability: Phase-Locked Loop with bypass option
• Input/Output Characteristics: Crystal input support and CMOS-compatible output
• Supply Voltage Range: Operating voltage compatibility
• Mounting Type: Surface mount technology
• Package Compatibility: Physical and electrical pin compatibility

The identified substitute part 5L2503-000NVGI is a Renesas Electronics Clock Generator from the MicroCLock™ series with Active product status. This part shares the same manufacturer, clock generator functionality, PLL capability, crystal input support, and surface mount technology as the main part.

Parameter Comparison

Engineering Selection Recommendations

The 525-01RLF is classified as Obsolete, making the identification of active alternatives essential for procurement and design continuity. The substitute part 5L2503-000NVGI carries Active product status from the same manufacturer, Renesas Electronics Corporation, ensuring ongoing availability and technical support.

Both parts meet REACH compliance requirements and carry identical ECCN classifications (EAR99), confirming regulatory alignment. The substitute part demonstrates an extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C), providing broader environmental applicability.

Selection between these parts must account for application-specific requirements regarding frequency range, supply voltage, package footprint, and circuit count. The 525-01RLF operates at 160MHz maximum with dual supply voltage support (3V ~ 5.5V), while the 5L2503-000NVGI operates at 32.768kHz with narrower supply voltage range (1.71V ~ 1.89V). Package differences (28-SSOP versus 12-UFDFN) and circuit count variations (1 versus 3) require PCB layout and schematic evaluation.

Frequently Asked Questions (FAQ)

Q: Can the 5L2503-000NVGI directly replace the 525-01RLF in existing designs?

A: Direct replacement requires verification of frequency requirements, supply voltage compatibility, package footprint availability on the PCB, and circuit count needs. The substitute operates at significantly lower maximum frequency (32.768kHz versus 160MHz) and requires different supply voltage levels.

Q: What are the key differences in package specifications?

A: The 525-01RLF uses a 28-SSOP package (0.154" width, 3.90mm), while the 5L2503-000NVGI uses a 12-UFDFN package (2.5x2.5mm). These are physically distinct packages requiring different PCB layouts and land patterns.

Q: Are both parts compliant with environmental regulations?

A: Both parts are REACH Unaffected and carry EAR99 ECCN classification. Both maintain MSL 1 (Unlimited) moisture sensitivity levels, indicating equivalent handling requirements.

Q: What is the significance of the Active versus Obsolete product status?

A: The 525-01RLF's Obsolete status indicates discontinued manufacturing and limited future availability. The 5L2503-000NVGI's Active status confirms current production and ongoing manufacturer support, making it suitable for new designs and long-term procurement planning.

Q: How do the supply voltage ranges differ?

A: The 525-01RLF operates across 3V to 5.5V, supporting standard logic supply voltages. The 5L2503-000NVGI operates across 1.71V to 1.89V, requiring low-voltage power supply design. Applications must verify power supply compatibility before substitution.

Q: What does the Ratio - Input:Output parameter indicate?

A: This parameter specifies the frequency multiplication or division relationship. The 525-01RLF provides a 1:2 ratio (one input produces two outputs), while the 5L2503-000NVGI provides a 1:3 ratio (one input produces three outputs), affecting output frequency distribution architecture.
