Substitute Part Grouping Explanation
Substitution eligibility for the 8302AMLF is determined by the following critical parameters:
- Functional Type: Fanout Buffer (Distribution) IC with 1:2 ratio configuration
- Maximum Frequency: 200 MHz operation capability
- Input/Output Signal Compatibility: LVCMOS signal support (primary requirement)
- Supply Voltage Range: Must support the operating voltage envelope
- Package Compatibility: Surface mount configuration with compatible pinout
- Product Status: Active or current production status preferred for long-term availability
The Renesas 5PB1102CMGI8 meets these substitution criteria as an active production alternative within the Renesas clock buffer product family.

Engineering Selection Recommendations
The 5PB1102CMGI8 is the manufacturer-recommended substitute for the obsolete 8302AMLF. Both devices are manufactured by Renesas Electronics Corporation and maintain ROHS3 compliance and MSL Level 1 ratings.
Key considerations for selection:
Functional Compatibility: Both parts provide identical 1:2 fanout buffer functionality at 200 MHz maximum frequency with LVCMOS signal support.
Supply Voltage: The 5PB1102CMGI8 supports an extended lower voltage range (1.71V minimum) compared to the 8302AMLF (3.135V minimum), providing greater design flexibility for lower-voltage applications.
Operating Temperature Range: The 5PB1102CMGI8 extends the operating temperature range to -40°C ~ 85°C, compared to the 8302AMLF range of 0°C ~ 70°C, enabling use in wider environmental conditions.
Package Transition: The 5PB1102CMGI8 uses 8-UFDFN (2x2) packaging instead of 8-SOIC. This represents a package footprint change requiring PCB layout modification.
Product Availability: The 5PB1102CMGI8 maintains active production status with substantial inventory availability, ensuring long-term supply continuity.
Frequently Asked Questions (FAQ)
Q: Can the 5PB1102CMGI8 directly replace the 8302AMLF without PCB modifications?
A: No. While functionally equivalent, the 5PB1102CMGI8 uses 8-UFDFN (2x2) packaging versus the 8-SOIC package of the 8302AMLF. PCB layout and footprint changes are required.
Q: Are the signal input/output specifications compatible between these parts?
A: Both parts support LVCMOS signal levels. The 8302AMLF additionally supports LVTTL input/output, while the 5PB1102CMGI8 is specified for LVCMOS only. For LVCMOS-only applications, compatibility is confirmed.
Q: What is the impact of the extended voltage range on the 5PB1102CMGI8?
A: The 5PB1102CMGI8 supports supply voltages from 1.71V to 3.465V, compared to 3.135V to 3.465V for the 8302AMLF. This extended range provides design flexibility for lower-voltage system implementations without functional degradation.
Q: Does the extended operating temperature range of the 5PB1102CMGI8 affect reliability?
A: The 5PB1102CMGI8 is qualified for -40°C to 85°C operation, exceeding the 8302AMLF specification of 0°C to 70°C. Both devices maintain identical MSL Level 1 moisture sensitivity ratings and ROHS3 compliance.
Q: Are there inventory or lead time advantages to using the 5PB1102CMGI8?
A: The 5PB1102CMGI8 maintains active production status with 18,900 units in stock, compared to the obsolete 8302AMLF status. Active production ensures sustained availability for ongoing production requirements.
