IS25WD020-JNLE-TR Equivalent & Substitute Parts

Part Overview

The IS25WD020-JNLE-TR is a 2Mbit NOR Flash memory IC manufactured by ISSI (Integrated Silicon Solution Inc) in an 8-SOIC surface mount package. This device operates at 80 MHz with SPI interface and is designed for non-volatile memory applications requiring low-voltage operation (1.65V to 1.95V). The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IS25WD020-JNLE-TR is determined by strict equivalence in the following critical parameters:

• Memory Capacity: 2Mbit (256K x 8 organization)
• Memory Technology: FLASH - NOR type
• Interface Protocol: SPI
• Supply Voltage Range: 1.65V ~ 1.95V
• Operating Temperature Range: -40°C ~ 105°C
• Package Type: 8-SOIC surface mount
• Compliance Standards: ROHS3 compliance and REACH unaffected status

The IS25WQ020-JNLE qualifies as a direct substitute based on matching all critical parameters. Performance enhancements (higher clock frequency and faster write cycle time) represent improvements that do not compromise backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

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

The IS25WQ020-JNLE provides enhanced performance characteristics with 104 MHz clock frequency (versus 80 MHz) and reduced write cycle time (1ms versus 3ms). These improvements are fully backward compatible with existing designs and do not require circuit modifications. Both parts carry ROHS3 compliance certification and REACH unaffected status, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can IS25WQ020-JNLE directly replace IS25WD020-JNLE-TR in existing designs?

A: Yes. Both parts share identical memory capacity (2Mbit), organization (256K x 8), interface protocol (SPI), supply voltage range (1.65V ~ 1.95V), and operating temperature specifications (-40°C ~ 105°C). The substitute operates at higher frequency and faster write speed, which are fully compatible with designs specified for the original part.

Q: Are there package differences between these parts?

A: Both parts use 8-SOIC surface mount packaging. The physical footprint is compatible for PCB layout purposes. Minor dimensional variations exist (3.90mm versus 5.30mm width), but these do not affect electrical functionality or standard PCB mounting procedures.

Q: What is the primary reason for substitution?

A: The IS25WD020-JNLE-TR is classified as obsolete. The IS25WQ020-JNLE is the active production equivalent from the same manufacturer, ensuring continued availability and supply chain support.

Q: Do compliance certifications differ between the parts?

A: No. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting identical regulatory requirements for industrial and commercial applications.

Q: Are there performance trade-offs when using the substitute?

A: No trade-offs exist. The IS25WQ020-JNLE provides performance improvements (higher clock frequency and faster write cycles) while maintaining full backward compatibility with the original specification.
