ICS513M Clock Generator Equivalent & Substitute Parts

Part Overview

The ICS513M is a Clock Generator and Fanout Distribution IC manufactured by Renesas Electronics Corporation, designed for 140MHz maximum frequency applications in 8-SOIC surface mount packaging. This part is classified as obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations. The ICS513M features integrated PLL with bypass capability, supporting both clock and crystal inputs with CMOS output configuration.

Substitute Part Grouping Explanation

Substitute parts for the ICS513M are identified based on the following critical parameters that determine functional compatibility:

Mechanical Compatibility:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) — identical footprint required for direct PCB substitution
• Mounting Type: Surface Mount — consistent with original design

Electrical Compatibility:

• Voltage - Supply: 3V ~ 5.5V — operating range must encompass or match the original specification
• Input Type: Clock, Crystal — must support both input modes
• Output Type: CMOS or CMOS/TTL — CMOS output is baseline; TTL compatibility is acceptable
• Number of Circuits: 1 — single circuit configuration
• Ratio - Input:Output: 1:2 — frequency multiplication factor must be maintained
• PLL with Bypass: Required functionality

Performance Consideration:

• Frequency - Max: Substitute must support minimum 140MHz; higher frequency capability is acceptable

The substitute parts NB3N502DG and NB3N502DR2G (both onsemi PLL Clock Multiplier ICs) meet all mechanical and electrical compatibility criteria. These parts are functionally equivalent with enhanced specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Ongoing Production: The NB3N502DG and NB3N502DR2G are direct functional substitutes for the obsolete ICS513M. Both parts are manufactured by onsemi and maintain active product status, ensuring long-term availability and supply chain stability.

Compliance Advantage: Both substitute parts achieve ROHS3 compliance, addressing regulatory requirements that the original ICS513M does not meet. This is significant for applications subject to RoHS directives in the EU and equivalent markets.

Performance Enhancement: The substitute parts support 190MHz maximum frequency, exceeding the ICS513M specification of 140MHz. This provides additional operational margin for existing designs and enables support for higher-frequency applications without component redesign.

Temperature Range Expansion: The onsemi substitutes operate across -40°C to 85°C, compared to the ICS513M range of 0°C to 70°C. This extended range accommodates industrial and automotive temperature environments.

Packaging Options: NB3N502DG is supplied in Tube packaging; NB3N502DR2G is supplied in Tape & Reel format. Selection depends on production volume and assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can NB3N502DG and NB3N502DR2G be used interchangeably with ICS513M? A: Yes. Both parts are electrically and mechanically compatible. The difference between NB3N502DG and NB3N502DR2G is packaging format only (Tube vs. Tape & Reel); electrical specifications are identical.

Q: What is the primary reason for substitution? A: The ICS513M is obsolete. The onsemi NB3N502 series provides equivalent functionality with active product status, ensuring continued availability for production and support applications.

Q: Are there any design modifications required when switching from ICS513M to NB3N502DG or NB3N502DR2G? A: No design modifications are required. Both substitute parts use the identical 8-SOIC package footprint, support the same supply voltage range (3V ~ 5.5V), and maintain the 1:2 input-to-output frequency ratio with PLL and bypass functionality.

Q: How do the operating temperature ranges differ? A: The ICS513M operates from 0°C to 70°C. The NB3N502 series operates from -40°C to 85°C, providing extended temperature capability suitable for industrial and automotive applications.

Q: What is the significance of ROHS3 compliance on the substitute parts? A: ROHS3 compliance indicates adherence to current Restriction of Hazardous Substances directives. The ICS513M is RoHS non-compliant, while both NB3N502 variants are ROHS3 compliant, meeting regulatory requirements for EU and equivalent markets.

Q: Which packaging format should be selected? A: NB3N502DG (Tube) is suitable for lower-volume production and manual assembly. NB3N502DR2G (Tape & Reel) is optimized for high-volume automated assembly processes. Electrical performance is identical.

Q: Is the maximum frequency specification important for my application? A: The substitute parts support 190MHz, compared to the ICS513M specification of 140MHz. If your application operates at or below 140MHz, both parts are fully compatible. The higher frequency capability of the substitutes provides additional operational margin.
