Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 8312AYILF Clock Fanout Buffer are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Functional Parameters:

• Fanout Buffer (Distribution) topology with 1:12 input-to-output ratio
• Maximum operating frequency of 250 MHz
• LVCMOS and LVTTL input signal compatibility
• LVCMOS output signal compatibility
• Single circuit configuration

Electrical Parameters:

• Supply voltage range supporting 1.6V to 3.465V operation
• Operating temperature range of -40°C to 85°C

Mechanical Parameters:

• 32-LQFP package configuration (7x7 mm footprint)
• Surface mount mounting type

The substitute parts identified (NB3V8312CFAG and NB3V8312CFAR2G) from onsemi maintain identical functional specifications, electrical performance characteristics, and mechanical package compatibility with the original Renesas 8312AYILF device. Both substitute parts are classified as active products with current manufacturing status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

NB3V8312CFAG (onsemi) - Tray Packaging:

This substitute part is qualified for direct replacement in applications where the 8312AYILF is currently deployed. The NB3V8312CFAG maintains full functional and electrical compatibility while offering the advantage of active product status. This part carries ROHS3 compliance certification and REACH Unaffected status, providing improved regulatory alignment compared to the obsolete Renesas device. The tray packaging format is suitable for standard manufacturing and assembly processes.

NB3V8312CFAR2G (onsemi) - Cut Tape & Digi-Reel Packaging:

This substitute part is functionally identical to the NB3V8312CFAG with the distinction of Cut Tape and Digi-Reel packaging format. The NB3V8312CFAR2G is appropriate for high-volume production environments and automated pick-and-place assembly operations. This variant also carries ROHS3 compliance and REACH Unaffected certifications. Significantly higher inventory availability (33,300 pieces) supports extended production runs and supply chain continuity.

Selection Basis:

Both onsemi substitute parts satisfy the core functional requirements of the 8312AYILF Clock Fanout Buffer topology. The selection between NB3V8312CFAG and NB3V8312CFAR2G depends on packaging and assembly process requirements rather than electrical performance. Both parts are active products with current manufacturing support, providing superior long-term availability compared to the obsolete Renesas original.

Frequently Asked Questions (FAQ)

Q: Can the NB3V8312CFAG and NB3V8312CFAR2G be used interchangeably with the 8312AYILF?

A: Yes. Both onsemi parts maintain identical electrical specifications, functional topology, and mechanical package configuration. The 1:12 fanout ratio, 250 MHz maximum frequency, LVCMOS/LVTTL signal compatibility, and 32-LQFP package ensure direct functional equivalence. The difference between these two onsemi variants is packaging format only.

Q: What is the difference between NB3V8312CFAG and NB3V8312CFAR2G?

A: Both parts are electrically and functionally identical. The NB3V8312CFAG is supplied in tray packaging, while the NB3V8312CFAR2G is supplied in Cut Tape and Digi-Reel format. The packaging selection depends on manufacturing process requirements and assembly automation capabilities.

Q: Are there any output signal compatibility differences between the original and substitute parts?

A: The original 8312AYILF supports both LVCMOS and LVTTL output signals. The onsemi substitutes (NB3V8312CFAG and NB3V8312CFAR2G) support LVCMOS output only. For applications requiring LVTTL output compatibility, this difference must be evaluated against specific system requirements.

Q: What is the supply voltage range for the substitute parts?

A: The onsemi substitutes operate across a continuous supply voltage range of 1.6V to 3.465V. The original 8312AYILF specifies discrete voltage ranges (1.6V ~ 2V, 2.375V ~ 2.625V, 3.135V ~ 3.465V). The onsemi parts provide broader voltage flexibility within the same overall range.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both NB3V8312CFAG and NB3V8312CFAR2G carry ROHS3 compliance certification. The original 8312AYILF is RoHS non-compliant. This represents an improvement in regulatory compliance for new designs or production transitions.

Q: What is the Moisture Sensitivity Level (MSL) for the substitute parts?

A: Both onsemi substitutes carry an MSL rating of 2 with a 1-year shelf life specification. This indicates standard moisture sensitivity handling requirements for surface mount components.

Q: Is the 32-LQFP package footprint identical across all three parts?

A: Yes. All three parts utilize the 32-LQFP package with a 7x7 mm footprint. PCB layout and assembly processes require no modification for substitution.

Q: What inventory levels are available for the substitute parts?

A: NB3V8312CFAG (tray packaging) has 2,120 pieces in stock. NB3V8312CFAR2G (Cut Tape & Digi-Reel) has 33,300 pieces in stock. The original 8312AYILF has 1,390 pieces available as obsolete stock.
