Renesas Electronics 501BMILF Clock Multiplier IC Equivalent & Substitute Parts

Part Overview

The Renesas Electronics 501BMILF is an obsolete Clock Multiplier IC designed for 15MHz applications in 8-SOIC surface mount packaging. This device features Phase-Locked Loop (PLL) technology with a 1:1 input-to-output ratio and operates across a 3.14V to 5.25V supply voltage range. Due to its obsolete product status, identifying functionally compatible substitute components is essential for system redesign, legacy product support, and continued manufacturing operations.

Substitute Part Grouping Explanation

Substitution of the 501BMILF Clock Multiplier IC is determined by the following critical parameters:

Functional Compatibility Criteria:

• Device Type: Clock generation and timing control capability
• PLL Functionality: Phase-Locked Loop support for frequency synthesis
• Input/Output Interface: Clock or crystal input with CMOS-compatible output
• Frequency Range: Maximum operating frequency of 15MHz or higher
• Supply Voltage Compatibility: Operating range that encompasses or exceeds 3.14V to 5.25V
• Operating Temperature Range: Support for -40°C to 85°C industrial temperature specifications

Mechanical Compatibility Criteria:

• Mounting Type: Surface mount technology
• Package Form Factor: 8-pin or equivalent pin-count packages suitable for PCB integration

The substitute part 5L2503-000NVGI is identified as a manufacturer-recommended alternative based on shared clock/timing functionality, PLL capability, surface mount packaging, and overlapping operating temperature specifications. However, differences in package type, frequency range, supply voltage, and circuit count require engineering evaluation for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 501BMILF is classified as obsolete, making the active-status 5L2503-000NVGI the manufacturer-recommended substitute for ongoing production and support scenarios.

Compliance and Certification: Both parts maintain REACH Unaffected status and EAR99 ECCN classification, ensuring regulatory consistency. The 5L2503-000NVGI carries RoHS3 compliance certification, providing additional environmental compliance assurance for new designs.

Substitution Feasibility: Direct substitution requires engineering validation due to significant differences in frequency range (15MHz vs. 32.768kHz), supply voltage requirements (3.14V–5.25V vs. 1.71V–1.89V), package form factor (8-SOIC vs. 12-UFDFN), and circuit count (1 vs. 3). The 5L2503-000NVGI is suitable for applications requiring low-frequency crystal oscillator functionality with multiple output circuits, whereas the 501BMILF was designed for higher-frequency clock multiplication tasks.

Frequently Asked Questions (FAQ)

Q: Can the 5L2503-000NVGI directly replace the 501BMILF in existing designs?

A: Direct replacement is not recommended without circuit redesign. The substitute part operates at significantly lower maximum frequency (32.768kHz vs. 15MHz), requires different supply voltage levels (1.71V–1.89V vs. 3.14V–5.25V), and uses a different package form factor (12-UFDFN vs. 8-SOIC). Application-specific evaluation is required.

Q: What are the key differences between these clock timing components?

A: The 501BMILF is a clock multiplier with 1:1 input-to-output ratio designed for 15MHz operation. The 5L2503-000NVGI is a clock generator with 1:3 ratio and three output circuits optimized for 32.768kHz crystal oscillator applications. These represent different functional categories within the clock/timing component family.

Q: Are both parts suitable for industrial temperature range applications?

A: Yes, both parts support the -40°C to 85°C operating temperature range, meeting industrial specification requirements.

Q: What packaging considerations apply to substitution?

A: The 501BMILF uses 8-SOIC (0.154", 3.90mm width) surface mount packaging, while the 5L2503-000NVGI uses 12-UFDFN (2.5x2.5) packaging. PCB layout modifications and component placement adjustments are necessary for any substitution attempt.

Q: Do both parts use Phase-Locked Loop technology?

A: Yes, both the 501BMILF and 5L2503-000NVGI incorporate PLL functionality for frequency synthesis and clock generation.

Q: What is the regulatory status of these components?

A: Both parts maintain REACH Unaffected status and EAR99 ECCN classification. The 5L2503-000NVGI additionally carries RoHS3 compliance certification.
