Substitute Part Grouping Explanation

Substitution eligibility for the IS25LP01GG-RHLE is determined by strict equivalence across the following critical parameters:

Memory Capacity & Organization: Both parts must provide 1Gbit capacity with 128M x 8 organization to ensure software compatibility and address mapping consistency.

Interface Specification: Both parts must support SPI Quad I/O, QPI, and DTR protocols at 166 MHz to maintain functional compatibility with host controllers and firmware implementations.

Electrical Performance: Access time (6 ns), write cycle times (70µs word / 2ms page), and supply voltage range (2.3V ~ 3.6V) must be identical to ensure timing-critical operations function without modification.

Environmental & Compliance: Operating temperature range (-40°C ~ 105°C), RoHS3 compliance, and MSL rating (3) must match to maintain system reliability and regulatory requirements.

Manufacturer & Product Status: Both parts are manufactured by ISSI with active product status, ensuring continued availability and technical support.

The IS25LP01GG-RMLE-TY meets all these criteria and qualifies as a parametric equivalent substitute.
