Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IS25WD020-JKLE-TR is determined by the following critical parameters:

• Memory Capacity: 2Mbit (256K x 8 organization)
• Memory Technology: FLASH - NOR
• Interface Protocol: SPI
• Package Format: 8-WSON (6x5)
• Supply Voltage Range: 1.65V ~ 1.95V
• Operating Temperature Range: -40°C ~ 105°C
• Compliance Standards: ROHS3, REACH Unaffected

The IS25WQ020-JKLE qualifies as a direct substitute because it maintains identical memory capacity, organization, interface, package, voltage specifications, and temperature range. Differences in clock frequency and write cycle time represent performance enhancements rather than compatibility constraints.

Parameter Comparison

Engineering Selection Recommendations

The IS25WQ020-JKLE is a qualified substitute for the obsolete IS25WD020-JKLE-TR. Both components maintain identical electrical specifications for memory capacity, interface protocol, voltage supply, and operating temperature range. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The IS25WQ020-JKLE offers improved performance characteristics with higher clock frequency (104 MHz versus 80 MHz) and reduced write cycle time (1ms versus 3ms). These enhancements are backward-compatible with applications designed for the original part, as the substitute operates within the same voltage and temperature parameters and uses the identical package footprint.

Both components carry ROHS3 compliance and identical MSL ratings, confirming equivalent environmental and handling requirements for manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can IS25WQ020-JKLE be used as a direct replacement for IS25WD020-JKLE-TR?

A: Yes. Both parts share identical memory capacity (2Mbit), organization (256K x 8), SPI interface, supply voltage (1.65V ~ 1.95V), operating temperature range (-40°C ~ 105°C), and 8-WSON package format. The substitute is pin-compatible and functionally equivalent.

Q: What are the differences between these two parts?

A: The IS25WQ020-JKLE operates at 104 MHz clock frequency compared to 80 MHz for the IS25WD020-JKLE-TR. Write cycle time is reduced from 3ms to 1ms. These represent performance improvements with no impact on compatibility.

Q: Are there any package or footprint differences?

A: No. Both components use the 8-WSON (6x5) package format with identical pinout and mechanical dimensions. PCB layout and assembly processes require no modification.

Q: What is the availability status of each part?

A: The IS25WD020-JKLE-TR is classified as obsolete. The IS25WQ020-JKLE is in active production with confirmed inventory availability, making it the recommended choice for new designs and ongoing system support.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of 3 (168 Hours), confirming equivalent environmental and manufacturing compliance.
