Key Parameters

Substitute Part Grouping Explanation

Substitution of the 72V265LA15PF is determined by strict equivalence across the following critical parameters:

• Memory configuration: 16K x 18 (288K total capacity)
• Function: Synchronous FIFO with uni-directional bus architecture
• Supply voltage range: 3V to 3.6V
• Package type: 64-TQFP (14x14mm) surface mount
• Programmable flags, retransmit capability, and FWFT support
• Operating temperature range: 0°C to 70°C
• Mounting type: Surface Mount

The 72V265LA10PFG qualifies as a direct substitute based on identical memory configuration, function, voltage specifications, package format, and feature set. Performance parameters (access time and data rate) represent improvements over the original part, making this substitute suitable for applications requiring equal or enhanced performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 72V265LA10PFG is the qualified substitute for the 72V265LA15PF based on the following engineering criteria:

Functional equivalence is established through identical memory architecture (16K x 18), FIFO operation mode, uni-directional bus configuration, and feature support (programmable flags, retransmit capability, FWFT). Both parts operate within the same supply voltage range (3V to 3.6V) and temperature envelope (0°C to 70°C), ensuring direct compatibility in existing circuit designs.

The substitute part offers performance improvements with 100MHz data rate versus 66.7MHz and 6.5ns access time versus 10ns, representing enhanced speed characteristics that maintain backward compatibility with applications designed for the original part.

Product status transition from obsolete to active status for the substitute part ensures long-term availability and supply chain continuity. The upgrade to ROHS3 compliance addresses regulatory requirements for new designs and manufacturing environments, while the original part's RoHS non-compliant status may present procurement and environmental compliance challenges.

Both parts maintain identical moisture sensitivity classification (MSL 3, 168 hours) and package specifications (64-TQFP, 14x14mm surface mount), eliminating mechanical redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can the 72V265LA10PFG directly replace the 72V265LA15PF in existing designs?

A: Yes. Both parts share identical memory configuration (16K x 18), FIFO function, supply voltage range (3V to 3.6V), operating temperature range (0°C to 70°C), and 64-TQFP package format. The substitute part's improved access time (6.5ns vs. 10ns) and data rate (100MHz vs. 66.7MHz) are backward compatible with designs specified for the original part.

Q: What are the key differences between these parts?

A: The primary differences are performance specifications and product status. The 72V265LA10PFG provides faster access time and higher data rate, operates as an active product with current availability, and meets ROHS3 compliance. The 72V265LA15PF is obsolete and RoHS non-compliant.

Q: Are there any package or pinout differences?

A: No. Both parts use identical 64-TQFP (14x14mm) surface mount packaging with the same pin configuration, eliminating any PCB layout or mechanical redesign requirements.

Q: What is the moisture sensitivity consideration for these parts?

A: Both parts carry MSL 3 classification with a 168-hour floor life. Identical handling and storage requirements apply to both components.

Q: Why is the substitute part listed as active while the original is obsolete?

A: The 72V265LA10PFG represents the current production equivalent within the 72V series FIFO family. Renesas Electronics has transitioned manufacturing to this higher-performance variant, making it the recommended selection for new designs and ongoing system support.
