ICS501MIT Clock Generator IC Equivalent & Substitute Parts

Part Overview

The ICS501MIT is a Clock Generator IC manufactured by Renesas Electronics Corporation, designed for 140MHz clock generation applications. It features a Phase-Locked Loop (PLL) with multiplier capability, supporting both clock and crystal inputs with CMOS output. The device operates across a 3V to 5.25V supply range and is housed in an 8-SOIC surface mount package.

The ICS501MIT is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support legacy system maintenance or redesign initiatives.

Substitute Part Grouping Explanation

Substitution of the ICS501MIT is determined by strict equivalence across the following critical parameters:

  • Frequency specification: Maximum 140MHz operation
  • PLL architecture: Phase-Locked Loop with multiplier function
  • Input/Output configuration: Clock or crystal input with CMOS output
  • Electrical characteristics: 3V to 5.25V supply voltage range
  • Temperature range: -40°C to 85°C operating window
  • Package form factor: 8-SOIC surface mount package with 0.154" width (3.90mm)
  • Circuit count: Single circuit configuration
  • Input:Output ratio: 1:1 ratio specification

The substitute part 501MILFT maintains identical electrical and mechanical specifications across all these parameters, establishing direct functional equivalence.

Engineering Selection Recommendations

The 501MILFT serves as a direct functional substitute for the ICS501MIT across all electrical and mechanical specifications. The primary distinctions are non-technical in nature:

Product Status: The 501MILFT is classified as Active, whereas the ICS501MIT is Obsolete. This status difference indicates ongoing manufacturer support and availability for the 501MILFT.

Compliance: The 501MILFT carries ROHS3 compliance certification, while the ICS501MIT is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the 501MILFT is the appropriate selection.

Packaging Format: The ICS501MIT is supplied in tube packaging, while the 501MILFT is supplied in Tape & Reel (TR) format. Packaging selection depends on assembly process requirements and volume considerations.

For new designs or system redesigns, the 501MILFT is the recommended selection due to active product status and regulatory compliance. For legacy system maintenance requiring exact packaging compatibility, packaging format must be evaluated against assembly capabilities.

Frequently Asked Questions (FAQ)

Q: Can the 501MILFT directly replace the ICS501MIT in existing designs?

A: Yes. The 501MILFT maintains identical electrical specifications, frequency range, supply voltage, operating temperature, and 8-SOIC package form factor. Pin-for-pin compatibility is established across all functional parameters.

Q: What is the significance of the product status difference?

A: The ICS501MIT is classified as Obsolete, indicating discontinued manufacturing and limited availability. The 501MILFT is Active, meaning it is currently manufactured and supported by Renesas Electronics Corporation, ensuring supply chain continuity.

Q: Does the RoHS compliance difference affect substitution?

A: RoHS compliance is a regulatory and environmental consideration, not a functional one. If your application or market requires RoHS compliance, the 501MILFT is the appropriate selection. If RoHS compliance is not a requirement, both parts are functionally equivalent.

Q: Are there packaging considerations for substitution?

A: Yes. The ICS501MIT is supplied in tube packaging, while the 501MILFT is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes. If your assembly process requires tube packaging, this must be addressed separately or the assembly process must accommodate Tape & Reel format.

Q: Is the 501MILFT available in the same 8-SOIC package?

A: Yes. Both parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package with identical pinout and mechanical dimensions.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching frequency specification (140MHz), PLL architecture, input/output configuration (Clock/Crystal input, CMOS output), supply voltage range (3V to 5.25V), operating temperature range (-40°C to 85°C), and package form factor (8-SOIC). All these parameters are identical between the ICS501MIT and 501MILFT.
