Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICS512MIT is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) — physical and electrical compatibility requirement
• Voltage - Supply: 3V ~ 5.5V — operating voltage range must encompass or match the original specification
• Operating Temperature: -40°C ~ 85°C — thermal operating range
• PLL: Yes with Bypass — functional architecture requirement
• Input: Clock, Crystal — input signal compatibility
• Ratio - Input:Output: 1:2 — frequency multiplication factor
• Number of Circuits: 1 — single circuit configuration
• Mounting Type: Surface Mount — assembly compatibility

The substitute parts NB3N502DG and NB3N502DR2G, both manufactured by onsemi, meet all critical substitution parameters. Both parts are PLL Clock Multiplier ICs with identical package, voltage, temperature, and functional specifications. The primary difference between these substitutes is packaging format: NB3N502DG is supplied in Tube packaging, while NB3N502DR2G is supplied in Tape & Reel (TR) format.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The ICS512MIT is classified as Obsolete. Both substitute parts, NB3N502DG and NB3N502DR2G, are Active products from onsemi, ensuring continued availability and manufacturing support.

Compliance and Certification: The ICS512MIT is RoHS non-compliant. Both substitute parts are ROHS3 Compliant, meeting current regulatory requirements for electronic component manufacturing and assembly. Both substitutes maintain REACH Unaffected status and EAR99 ECCN classification, consistent with the original part.

Frequency Capability: The substitute parts feature a maximum frequency of 190MHz, exceeding the ICS512MIT specification of 160MHz. This provides additional operational margin for clock generation applications.

Output Configuration: The substitute parts support both CMOS and TTL output, compared to the ICS512MIT's CMOS-only output. This expanded output capability provides greater flexibility in system integration.

Packaging Format Selection:

• NB3N502DG (Tube): Suitable for lower-volume applications, prototype development, and manual assembly processes.
• NB3N502DR2G (Tape & Reel): Optimized for high-volume production and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can NB3N502DG and NB3N502DR2G be used interchangeably with the ICS512MIT?

A: Yes. Both parts meet all critical electrical and mechanical substitution parameters: identical 8-SOIC package, matching voltage supply range (3V ~ 5.5V), identical operating temperature range (-40°C ~ 85°C), PLL with bypass architecture, 1:2 input-to-output ratio, and single-circuit configuration. The primary difference is packaging format (Tube vs. Tape & Reel), which does not affect electrical performance or pin compatibility.

Q: What is the difference between NB3N502DG and NB3N502DR2G?

A: Both parts are electrically identical PLL Clock Multiplier ICs from onsemi with the same specifications. The distinction is packaging format: NB3N502DG is supplied in Tube packaging for lower-volume or manual assembly applications, while NB3N502DR2G is supplied in Tape & Reel format for high-volume automated assembly. Selection depends on production volume and assembly process requirements.

Q: Are the substitute parts pin-compatible with the ICS512MIT?

A: Yes. All three parts use the 8-SOIC (0.154", 3.90mm Width) package with identical pin configuration, ensuring direct mechanical and electrical compatibility without PCB redesign.

Q: What are the advantages of using NB3N502 substitutes over the obsolete ICS512MIT?

A: The onsemi NB3N502 series offers: Active product status with ongoing manufacturing support, ROHS3 compliance meeting current regulatory standards, higher maximum frequency capability (190MHz vs. 160MHz), expanded output options (CMOS and TTL), and improved availability through established distribution channels.

Q: Can the ICS512MIT be replaced in existing designs without modification?

A: Yes. The substitute parts maintain electrical and mechanical compatibility with the ICS512MIT. No PCB modifications or design changes are required for direct substitution. Existing firmware or configuration settings remain valid.

Q: What is the inventory status of these substitute parts?

A: NB3N502DG is available with 1502 pieces in stock. NB3N502DR2G is available with 2978 pieces in stock. Both are classified as New Original In Stock.
