Renesas 8302AMILF Clock Fanout Buffer - Equivalent & Substitute Parts

Part Overview

The Renesas 8302AMILF is a Clock Fanout Buffer (Distribution) IC with 1:2 ratio configuration, designed for clock distribution applications requiring up to 200 MHz frequency support. This device features LVCMOS and LVTTL input/output compatibility with 3.135V to 3.465V supply voltage operation across -40°C to 85°C temperature range in an 8-SOIC surface mount package.

The 8302AMILF is classified as obsolete product status. Identifying equivalent and substitute parts is necessary to ensure continued design support, maintain supply chain reliability, and enable component procurement for new production runs or design revisions.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 8302AMILF are identified based on the following critical parameters that determine functional and mechanical compatibility:

Core Functional Parameters:

• Fanout Buffer (Distribution) type with 1:2 ratio configuration
• Maximum frequency of 200 MHz
• LVCMOS and/or LVTTL input/output logic compatibility
• Operating temperature range of -40°C to 85°C

Electrical Parameters:

• Supply voltage compatibility within specified ranges
• Input and output logic level support

Mechanical Parameters:

• Surface mount packaging
• Pin count and footprint compatibility

Two substitute parts meet these criteria with varying degrees of compatibility:

NB3M8302CDG (onsemi) - Parametric equivalent with identical package (8-SOIC), matching all core electrical specifications and active product status.

5PB1102CMGI8 (Renesas Electronics Corporation) - Manufacturer-recommended substitute with different package format (8-UFDFN) but broader supply voltage range (1.71V ~ 3.465V) and active product status.

Parameter Comparison

Engineering Selection Recommendations

NB3M8302CDG (onsemi) is the preferred parametric equivalent for direct replacement in existing designs. This part maintains identical package geometry (8-SOIC), matching electrical specifications, and active product status. No PCB layout modifications are required. This option is suitable for designs where the original 8-SOIC footprint is already established and component procurement from alternative manufacturers is acceptable.

5PB1102CMGI8 (Renesas Electronics Corporation) is the manufacturer-recommended substitute. As an active Renesas product, it provides continued support from the original manufacturer. The extended supply voltage range (1.71V ~ 3.465V) offers greater design flexibility for low-voltage applications. However, the different package format (8-UFDFN versus 8-SOIC) requires PCB layout redesign and footprint modification. This option is recommended for new designs or design revisions where layout flexibility exists.

Both substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and identical operating temperature specifications. Selection between these options depends on design constraints: existing PCB layouts favor NB3M8302CDG, while new designs or those requiring extended voltage range support favor 5PB1102CMGI8.

Frequently Asked Questions (FAQ)

Q: Can NB3M8302CDG be used as a direct drop-in replacement for 8302AMILF?

A: Yes. NB3M8302CDG maintains identical package format (8-SOIC), pin configuration, and electrical specifications. No PCB modifications are required for direct substitution.

Q: What is the primary advantage of 5PB1102CMGI8 over NB3M8302CDG?

A: The 5PB1102CMGI8 features an extended supply voltage range (1.71V ~ 3.465V) compared to the fixed 3.135V ~ 3.465V range of both the original part and NB3M8302CDG. This enables operation in low-voltage applications. Additionally, as a Renesas product, it provides continued manufacturer support.

Q: Why does 5PB1102CMGI8 require PCB redesign?

A: The 5PB1102CMGI8 uses an 8-UFDFN (2x2) package, which has different physical dimensions and pin spacing compared to the 8-SOIC package of the original part. PCB footprint, trace routing, and component placement must be modified accordingly.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both NB3M8302CDG and 5PB1102CMGI8 are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), matching the compliance profile of the original 8302AMILF.

Q: What is the difference in logic level support between the substitutes?

A: NB3M8302CDG supports both LVCMOS and LVTTL input/output logic, matching the original part. The 5PB1102CMGI8 supports LVCMOS logic only. For designs requiring LVTTL compatibility, NB3M8302CDG is the appropriate choice.

Q: Can I use 5PB1102CMGI8 in a design originally specified for 3.3V supply?

A: Yes. The 5PB1102CMGI8 supply voltage range (1.71V ~ 3.465V) encompasses 3.3V operation. However, verify that the reduced minimum voltage (1.71V) does not conflict with other design requirements if operation at lower voltages is not intended.

Q: Are there any temperature or compliance differences between the substitutes?

A: No. All three parts (8302AMILF, NB3M8302CDG, and 5PB1102CMGI8) share identical operating temperature range (-40°C to 85°C), RoHS status (ROHS3 compliant), and MSL rating (1 - Unlimited).
