ICS527R-02 Equivalent & Substitute Parts

Part Overview

The ICS527R-02 is a fanout buffer (distribution) and zero delay buffer IC manufactured by Renesas Electronics Corporation, designed for clock/timing applications. Operating at a maximum frequency of 160MHz, this component features PECL input and CMOS output with a 1:2 input-to-output ratio in a 28-SSOP surface mount package.

The ICS527R-02 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this part number is no longer readily available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICS527R-02 is based on strict equivalence across the following critical parameters:

• Functional type: Fanout buffer with zero delay capability
• Frequency specification: 160MHz maximum operating frequency
• Input/output configuration: PECL input, CMOS output, 1:2 ratio
• PLL and divider/multiplier functionality: Both present
• Supply voltage range: 3.135V ~ 3.465V
• Package specification: 28-SSOP surface mount
• Operating temperature range: 0°C ~ 70°C
• Moisture sensitivity level: MSL 1

The substitute part 527R-02LF meets all these parameters while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 527R-02LF is a direct functional equivalent to the ICS527R-02 with identical electrical and mechanical specifications. The primary distinction is product lifecycle status and regulatory compliance.

The ICS527R-02 is obsolete and carries RoHS non-compliant status. The 527R-02LF maintains active product status and achieves ROHS3 compliance, making it suitable for new designs and applications subject to RoHS regulations. Both parts share identical supply voltage ranges, operating temperature specifications, frequency ratings, and 28-SSOP packaging.

For applications requiring RoHS compliance or long-term component availability, the 527R-02LF is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, either part may be used interchangeably based on availability.

Frequently Asked Questions (FAQ)

Q: Are the ICS527R-02 and 527R-02LF electrically interchangeable?

A: Yes. Both parts are fanout buffer ICs with identical electrical specifications: 160MHz maximum frequency, PECL input, CMOS output, 1:2 ratio, PLL functionality, and 3.135V ~ 3.465V supply voltage range.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and compliance. The ICS527R-02 is obsolete and RoHS non-compliant. The 527R-02LF is active and ROHS3 compliant. All functional and electrical parameters are identical.

Q: Can I use the 527R-02LF as a direct replacement in existing designs?

A: Yes. The 527R-02LF is pin-compatible and functionally equivalent. It uses the same 28-SSOP package with identical pinout, supply voltage requirements, and operating temperature range.

Q: Are there any compliance considerations when switching from ICS527R-02 to 527R-02LF?

A: The 527R-02LF achieves ROHS3 compliance, whereas the ICS527R-02 does not. If your application or market requires RoHS compliance, the 527R-02LF is the appropriate choice. Both parts maintain REACH Unaffected status.

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

A: Both the ICS527R-02 and 527R-02LF carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
