ICS552ARI-01 Equivalent & Substitute Parts

Part Overview

The ICS552ARI-01 is a Clock Generator and Fanout Distribution IC manufactured by Renesas Electronics Corporation, operating at a maximum frequency of 200MHz with a 1:8 input-to-output ratio. This device features a Phase-Locked Loop (PLL) for clock synthesis and supports both clock and crystal inputs with CMOS outputs. The ICS552ARI-01 is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

The ICS552ARI-01 can be substituted with the 552ARI-01LF based on the following electrical and mechanical compatibility criteria:

Key Parameters for Substitution:

• Identical maximum frequency: 200MHz
• Identical PLL functionality: Yes
• Identical input types: Clock, Crystal
• Identical output type: CMOS
• Identical number of circuits: 1
• Identical input-to-output ratio: 1:8
• Identical supply voltage range: 3V ~ 5.5V
• Identical operating temperature range: -40°C ~ 85°C
• Identical package type: 20-SSOP (0.154", 3.90mm Width)
• Identical moisture sensitivity level: MSL 1 (Unlimited)

The 552ARI-01LF represents the active production equivalent with improved compliance status and higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The 552ARI-01LF is the recommended substitute for the obsolete ICS552ARI-01. Both parts maintain identical electrical and mechanical specifications across all critical parameters including frequency, PLL functionality, supply voltage, operating temperature range, and package configuration.

The 552ARI-01LF offers the following advantages:

• Active product status ensures ongoing availability and manufacturing support
• ROHS3 compliance status versus non-compliant status of the original part
• Higher inventory availability (1550 Pcs versus 822 Pcs)
• Tube packaging for production handling

The electrical and functional equivalence between these parts is complete, with no design modifications required for direct substitution in existing applications.

Frequently Asked Questions (FAQ)

Q: Are the ICS552ARI-01 and 552ARI-01LF electrically identical?

A: Yes. Both parts share identical specifications for frequency (200MHz), PLL functionality, input/output types, supply voltage (3V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and all other electrical parameters.

Q: Can the 552ARI-01LF be used as a direct replacement in existing designs?

A: Yes. The 552ARI-01LF is a direct substitute. Both parts use the identical 20-SSOP package with matching pinout and electrical characteristics, requiring no circuit modifications.

Q: What is the difference between the ICS552ARI-01 and 552ARI-01LF?

A: The primary differences are product status (obsolete versus active), RoHS compliance (non-compliant versus ROHS3 compliant), and packaging format (unspecified versus tube). All electrical and mechanical specifications are identical.

Q: Why is the ICS552ARI-01 listed as obsolete?

A: The ICS552ARI-01 has been discontinued by Renesas Electronics Corporation. The 552ARI-01LF is the active production equivalent and should be used for new designs and ongoing production requirements.

Q: Are there any package compatibility concerns?

A: No. Both parts use the 20-SSOP (0.154", 3.90mm Width) package with identical pinout and footprint. PCB layouts and socket designs require no modification.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
