ICS525-01RI Clock Generator Equivalent & Substitute Parts

Part Overview

The ICS525-01RI is a Clock Generator and Fanout Distribution IC manufactured by Renesas Electronics Corporation. This device operates at a maximum frequency of 140MHz and is housed in a 28-SSOP surface mount package. The part features integrated PLL with bypass capability, accepts clock or crystal input, and provides CMOS output with a 1:2 input-to-output ratio.

The ICS525-01RI is classified as obsolete. Identifying equivalent and substitute parts is necessary for design continuity, procurement planning, and system maintenance when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICS525-01RI is determined by strict equivalence across the following critical parameters:

• Package and Pinout: 28-SSOP surface mount package with identical physical dimensions (0.154", 3.90mm Width)
• Electrical Specifications: Maximum frequency of 140MHz, supply voltage range 3V ~ 5.5V, operating temperature range -40°C ~ 85°C
• Functional Architecture: Clock Generator with Fanout Distribution capability, PLL with bypass, 1:2 input-to-output ratio, single circuit configuration
• Input/Output Characteristics: Clock or Crystal input, CMOS output

The substitute part 525-01RILF meets all these criteria and is manufactured by the same supplier (Renesas Electronics Corporation) within the same OSCaR™ series.

Parameter Comparison

Engineering Selection Recommendations

Both the ICS525-01RI and 525-01RILF are functionally equivalent across all electrical and mechanical parameters. The primary distinction is regulatory compliance status.

The 525-01RILF carries ROHS3 Compliant certification, whereas the ICS525-01RI is RoHS non-compliant. For applications subject to RoHS directives or procurement policies requiring RoHS compliance, the 525-01RILF is the appropriate selection.

Both parts maintain identical REACH Unaffected status and ECCN classification (EAR99). The 525-01RILF is supplied in tube packaging, while the ICS525-01RI packaging specification is not provided.

Frequently Asked Questions (FAQ)

Q: Can the 525-01RILF be used as a direct replacement for the ICS525-01RI?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical frequency specifications (140MHz maximum), supply voltage range (3V ~ 5.5V), operating temperature range (-40°C ~ 85°C), package type (28-SSOP), and functional architecture (Clock Generator with Fanout Distribution, PLL with bypass, 1:2 ratio).

Q: What is the difference between these two parts?

A: The primary difference is RoHS compliance status. The 525-01RILF is ROHS3 Compliant, while the ICS525-01RI is RoHS non-compliant. Both parts are REACH Unaffected. The 525-01RILF is supplied in tube packaging.

Q: Are there any pinout or footprint differences?

A: No. Both parts use the identical 28-SSOP package with dimensions of 0.154" × 3.90mm width. Pinout and PCB footprint are identical.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS compliance, select 525-01RILF. Both parts are classified as obsolete; long-term availability should be confirmed with the supplier.

Q: Are the supply voltage and operating temperature ranges identical?

A: Yes. Both parts operate across 3V to 5.5V supply voltage and -40°C to 85°C operating temperature range.
