Key Parameters

Substitute Part Grouping Explanation

Substitution of the 9DB106BFLF is determined by strict equivalence across the following critical parameters:

• Functional Equivalence: Input/Output configuration (1 input, 6 differential outputs), PLL functionality, and HCSL output signaling
• Electrical Compatibility: Maximum frequency (105MHz), supply voltage range (3.135V ~ 3.465V), and differential input/output characteristics
• Thermal Compatibility: Operating temperature range (0°C ~ 70°C)
• Mechanical Compatibility: Surface mount technology and pin count (28 pins)
• Regulatory Compliance: REACH and ECCN classifications

The 9DB106BGLF qualifies as a direct substitute based on identical electrical specifications and functional parameters. The primary difference is packaging format (28-TSSOP versus 28-SSOP) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The 9DB106BGLF is the recommended substitute for the obsolete 9DB106BFLF. Both parts maintain identical electrical and functional specifications, ensuring direct compatibility in PCIe clock distribution applications. The substitute offers the advantage of Active product status, providing improved long-term availability and supply chain reliability.

The primary design consideration is package format: the 9DB106BGLF uses 28-TSSOP packaging (0.173" width) compared to the original 28-SSOP (0.209" width). This represents a more compact footprint and is the current industry standard for this device family. PCB layout modifications may be required to accommodate the different package dimensions, but electrical performance and pin functionality remain identical.

Both parts maintain REACH Unaffected status and EAR99 ECCN classification, ensuring regulatory compliance across global markets. Moisture sensitivity level remains at MSL 1 (Unlimited) for both variants.

Frequently Asked Questions (FAQ)

Q: Can the 9DB106BGLF directly replace the 9DB106BFLF without circuit modifications?

A: Electrical and functional compatibility is complete. However, the package format differs (28-TSSOP versus 28-SSOP), requiring PCB footprint redesign. Pin assignments and electrical characteristics are identical.

Q: What is the difference between 28-SSOP and 28-TSSOP packaging?

A: Both are 28-pin surface mount packages with identical pin counts and electrical performance. The primary difference is package width: 28-SSOP measures 0.209" (5.30mm) while 28-TSSOP measures 0.173" (4.40mm). The TSSOP variant offers a more compact footprint.

Q: Why is the original 9DB106BFLF classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 9DB106BGLF represents the current active product offering from Renesas Electronics Corporation for this functional category.

Q: Are there any differences in supply voltage or operating temperature between these parts?

A: No. Both parts operate at identical supply voltage (3.135V ~ 3.465V) and temperature range (0°C ~ 70°C).

Q: What is the significance of the PLL (Phase-Locked Loop) feature?

A: The integrated PLL enables zero-delay buffering and jitter attenuation, critical for PCIe clock distribution where timing precision directly impacts signal integrity and system performance.

Q: Are both parts RoHS compliant?

A: The 9DB106BGLF is explicitly listed as ROHS3 Compliant. Both parts maintain REACH Unaffected status, indicating compliance with environmental regulations.
