Equivalent & Substitute Parts for ICS281PG

Part Overview

The ICS281PG is a Clock/Frequency Synthesizer IC manufactured by Renesas Electronics Corporation, part of the VersaClock® series. This device provides programmable clock synthesis with PLL capability, supporting input frequencies up to 200MHz with a 1:3 input-to-output ratio. The ICS281PG is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICS281PG is determined by strict equivalence across the following critical parameters:

• Package type and pinout compatibility: 16-TSSOP form factor
• Functional specifications: Clock/Frequency Synthesizer with PLL and bypass capability
• Electrical characteristics: 200MHz maximum frequency, 3.135V–3.465V supply voltage, 1:3 input-to-output ratio
• Input/Output configuration: Clock and Crystal inputs with CMOS output
• Divider/Multiplier functionality: Both present
• Thermal operating range: 0°C to 70°C
• Moisture sensitivity: MSL 1 (Unlimited)

The 281PGLF variant meets all these criteria and is therefore classified as a direct substitute for the obsolete ICS281PG.

Parameter Comparison

Engineering Selection Recommendations

The 281PGLF is the direct substitute for the obsolete ICS281PG. Both components share identical electrical and mechanical specifications, ensuring functional equivalence in clock synthesis applications. The primary distinction is product lifecycle status: the ICS281PG is obsolete, while the 281PGLF is active and available for procurement.

The 281PGLF offers an additional advantage in regulatory compliance. It meets ROHS3 standards, whereas the ICS281PG is RoHS non-compliant. For new designs or systems requiring compliance with current environmental regulations, the 281PGLF is the appropriate selection. Both components maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the 281PGLF directly replace the ICS281PG in existing designs?

A: Yes. The 281PGLF is electrically and mechanically equivalent to the ICS281PG. Both devices feature identical package geometry (16-TSSOP), pinout, supply voltage range (3.135V–3.465V), frequency specifications (200MHz maximum), and functional characteristics (PLL with bypass, 1:3 input-to-output ratio, CMOS output).

Q: What is the primary reason to transition from ICS281PG to 281PGLF?

A: The ICS281PG is obsolete and no longer manufactured. The 281PGLF is the active equivalent from Renesas Electronics Corporation and is the recommended part for new procurement and design implementations.

Q: Are there any compliance differences between these parts?

A: Yes. The 281PGLF is ROHS3 compliant, while the ICS281PG is RoHS non-compliant. For applications subject to environmental regulations, the 281PGLF is the appropriate choice. Both parts maintain REACH Unaffected status.

Q: Is the 16-TSSOP package identical between both parts?

A: Yes. Both the ICS281PG and 281PGLF use the 16-TSSOP package with 0.173" width and 4.40mm body width. No PCB layout modifications are required for substitution.

Q: Are the input and output specifications the same?

A: Yes. Both parts accept Clock and Crystal inputs and provide CMOS output with a 1:3 input-to-output ratio. PLL bypass functionality is present in both devices.
