Equivalent & Substitute Parts for 9DB233AFILFT

Part Overview

The 9DB233AFILFT is a PCI Express (PCIe) Fanout Buffer (Distribution) with Zero Delay Buffer functionality manufactured by Renesas Electronics Corporation. This IC operates at a maximum frequency of 110MHz with a 1:2 input-to-output ratio and differential HCSL output configuration. The part is currently classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and new designs requiring this clock distribution topology.

Substitute Part Grouping Explanation

Substitution eligibility for the 9DB233AFILFT is determined by strict equivalence across the following critical parameters:

• Maximum frequency: 110MHz
• Input/output configuration: Clock input with HCSL differential output
• Input-to-output ratio: 1:2
• Supply voltage range: 3.135V ~ 3.465V
• Operating temperature range: -40°C ~ 85°C
• PLL functionality: Present
• Differential signaling: Both input and output
• Mounting type: Surface Mount
• MSL rating: 1 (Unlimited)
• Regulatory compliance: REACH Unaffected, EAR99

The 9DB233AGILFT qualifies as a direct substitute based on identical electrical specifications and functional parameters. The primary difference is the package type (20-TSSOP versus 20-QSOP) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The 9DB233AGILFT is the recommended substitute for the obsolete 9DB233AFILFT. Both parts share identical electrical and functional specifications, including frequency range, supply voltage, operating temperature, and signal configuration. The substitute maintains REACH compliance and EAR99 classification.

The primary consideration for implementation is the package transition from 20-QSOP to 20-TSSOP. While both are 20-pin surface-mount packages, the TSSOP variant has a slightly larger body width (4.40mm versus 3.90mm). PCB layout modifications may be required to accommodate this dimensional change. The 9DB233AGILFT is currently in active production status with higher inventory availability (2300 units), ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 9DB233AGILFT be used as a direct replacement for the 9DB233AFILFT?

A: Yes. Both parts are electrically and functionally identical across all specified parameters including frequency, voltage, temperature range, and signal configuration. The primary difference is the package type (20-TSSOP versus 20-QSOP) and product status.

Q: What is the impact of the package change from 20-QSOP to 20-TSSOP?

A: The 20-TSSOP package is 0.5mm wider (4.40mm versus 3.90mm). PCB footprint and layout spacing must be verified to accommodate this dimensional difference. Pin pitch and electrical connectivity remain compatible.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts maintain identical REACH and ECCN classifications. The 9DB233AGILFT carries explicit ROHS3 compliance certification, while the main part does not specify RoHS status.

Q: What is the inventory status for each part?

A: The 9DB233AFILFT (obsolete) has 811 units available. The 9DB233AGILFT (active) has 2300 units available, providing superior supply chain availability.

Q: Are there any functional limitations when substituting the 9DB233AGILFT?

A: No functional limitations exist. All electrical specifications, operating ranges, and performance characteristics are identical between the two parts.
