V104YLF Equivalent & Substitute Parts

Part Overview

The V104YLF is a 10-bit LVDS receiver manufactured by Renesas Electronics Corporation in a 64-TQFP package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The part operates within a 3V to 3.6V supply range and supports industrial temperature specifications from -20°C to 85°C. Due to its obsolete status, sourcing equivalent or substitute components is necessary for production continuity and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the V104YLF is based on the following critical parameters that determine functional compatibility:

• Package Compatibility: 64-TQFP (10x10) form factor for direct PCB footprint alignment
• Protocol Alignment: LVDS input specification for signal integrity and interface matching
• Supply Voltage Range: Overlap or containment within 3V to 3.6V operating window
• Mounting Type: Surface mount technology for manufacturing process compatibility
• Thermal Operating Range: Support for -20°C to 85°C or extended range specifications
• Moisture Sensitivity: MSL 3 classification for handling and storage requirements

The BU90R104-E2 from Rohm Semiconductor meets these substitution criteria through identical package geometry, LVDS input protocol, compatible supply voltage range (2.3V to 3.6V), and equivalent moisture sensitivity classification.

Engineering Selection Recommendations

The BU90R104-E2 is the designated manufacturer-recommended substitute for the V104YLF. Selection of this alternative is supported by:

• Identical Physical Form Factor: Both components utilize 64-TQFP (10x10) packaging, enabling direct PCB footprint compatibility without layout modifications
• Active Product Status: The BU90R104-E2 maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete V104YLF
• Regulatory Compliance Alignment: Both parts share identical REACH and ECCN classifications, maintaining compliance requirements across supply chain and export documentation
• Extended Operating Range: The BU90R104-E2 provides expanded supply voltage range (2.3V to 3.6V) and lower temperature limit (-40°C), offering greater operational flexibility within the specified 3V to 3.6V design window
• Equivalent Handling Requirements: Matching MSL 3 classification ensures compatibility with existing moisture control and storage procedures

Frequently Asked Questions (FAQ)

Q: Can the BU90R104-E2 directly replace the V104YLF without PCB modifications?

A: Yes. Both components share identical 64-TQFP (10x10) package geometry and surface mount configuration, allowing direct footprint compatibility. No PCB layout changes are required.

Q: What is the primary reason for substitution?

A: The V104YLF is classified as obsolete. The BU90R104-E2 is an active product from Rohm Semiconductor, ensuring continued availability and manufacturing support.

Q: Are there voltage compatibility concerns?

A: No. The V104YLF operates at 3V to 3.6V. The BU90R104-E2 supports 2.3V to 3.6V, which fully contains the original operating range. Systems designed for 3V to 3.6V operation will function within the substitute's specifications.

Q: Do moisture sensitivity requirements differ?

A: No. Both components carry MSL 3 (168 Hours) classification, requiring identical handling, storage, and reflow procedures.

Q: What is the temperature operating range difference?

A: The V104YLF operates from -20°C to 85°C. The BU90R104-E2 extends the lower limit to -40°C, providing broader thermal coverage while maintaining the same upper temperature limit.

Q: Are regulatory classifications maintained?

A: Yes. Both parts share REACH Unaffected status and EAR99 ECCN classification, maintaining identical export and compliance documentation requirements.

Q: What is the functional difference between these components?

A: The V104YLF is specified as a 10-bit receiver. The BU90R104-E2 functions as a deserializer with 5 LVDS inputs and 35 LVCMOS outputs, operating at 3.92Gbps. Functional compatibility depends on system-level signal requirements and interface specifications.
