ICS514M Clock Generator Equivalent & Substitute Parts

Part Overview

The ICS514M is a Clock Generator and Fanout Distribution IC manufactured by Renesas Electronics Corporation, designed for 140MHz maximum frequency operation in 8-SOIC surface mount packaging. This part is classified as obsolete, necessitating identification of active equivalent components for new designs and production continuity. The ICS514M features integrated PLL with bypass capability, supporting both clock and crystal inputs with CMOS output configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ICS514M are identified based on strict electrical and mechanical compatibility criteria. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) — identical physical footprint required
• Mounting Type: Surface Mount — same assembly process compatibility
• PLL Configuration: Yes with Bypass — functional equivalence for clock generation
• Input Type: Clock, Crystal — compatible input signal sources
• Number of Circuits: 1 — single circuit configuration
• Ratio - Input:Output: 1:2 — identical frequency multiplication ratio
• Voltage - Supply: 3V ~ 5.5V — overlapping or compatible supply range
• Output Type: CMOS or CMOS/TTL — compatible output logic levels

The substitute parts NB3N502DG and NB3N502DR2G, manufactured by onsemi, satisfy all critical matching parameters. Both parts are active products with enhanced specifications including higher maximum frequency (190MHz) and extended operating temperature range (-40°C ~ 85°C), providing improved performance margins over the obsolete ICS514M.

Parameter Comparison

Engineering Selection Recommendations

Both NB3N502DG and NB3N502DR2G are functionally equivalent substitutes for the ICS514M with the following considerations:

Product Status: The NB3N502 series parts are active products from onsemi, ensuring long-term availability and manufacturing support compared to the obsolete ICS514M.

Compliance: Both substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements. The ICS514M is RoHS non-compliant, making the substitutes preferable for new designs subject to RoHS directives.

Performance Enhancement: The NB3N502 series provides higher maximum frequency (190MHz versus 140MHz) and extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C), offering improved performance margins for demanding applications.

Packaging Selection: NB3N502DG is supplied in Tube packaging, while NB3N502DR2G is supplied in Tape & Reel format. Selection between these variants depends on assembly process requirements and order quantities. Tape & Reel packaging is standard for automated pick-and-place assembly operations.

Frequently Asked Questions (FAQ)

Q: Can NB3N502DG and NB3N502DR2G be used interchangeably with ICS514M?

A: Yes. Both parts are electrically and mechanically equivalent substitutes. They share identical package footprint (8-SOIC), supply voltage range (3V ~ 5.5V), input/output configuration (Clock/Crystal input, CMOS output), and 1:2 frequency multiplication ratio. The primary difference is packaging format (Tube versus Tape & Reel).

Q: What is the difference between NB3N502DG and NB3N502DR2G?

A: Both parts are identical in electrical specifications and package type (8-SOIC). The distinction is packaging format: NB3N502DG uses Tube packaging for manual or small-volume assembly, while NB3N502DR2G uses Tape & Reel format optimized for automated assembly lines. Selection depends on production volume and assembly equipment.

Q: Are there any performance differences between ICS514M and the NB3N502 series?

A: The NB3N502 series provides enhanced specifications: maximum frequency of 190MHz (versus 140MHz for ICS514M) and extended operating temperature range of -40°C ~ 85°C (versus 0°C ~ 70°C). These improvements provide additional performance margin and broader environmental operating capability.

Q: Is the 8-SOIC package footprint identical between all three parts?

A: Yes. All three parts use 8-SOIC (0.154", 3.90mm Width) surface mount packaging with identical pin configuration and PCB footprint, enabling direct substitution without layout modifications.

Q: What is the significance of RoHS compliance for these parts?

A: The NB3N502 series is ROHS3 compliant, meeting current environmental regulations for lead-free and restricted substance requirements. The ICS514M is RoHS non-compliant, making it unsuitable for applications subject to RoHS directives. New designs should specify the NB3N502 series.

Q: Can the NB3N502 series operate at the same supply voltage as ICS514M?

A: Yes. Both the ICS514M and NB3N502 series support the identical supply voltage range of 3V ~ 5.5V, ensuring direct electrical compatibility without power supply modifications.
