Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SST26VF016B-80E/SN are qualified based on the following criteria:

Memory Capacity & Organization: All substitutes maintain 16Mbit capacity with 2M x 8 organization, ensuring direct functional equivalence in storage applications.

Interface Protocol: Substitute parts support SPI - Quad I/O interface with extended protocol support (QPI, DTR), providing backward compatibility with the main part's quad I/O mode.

Package Compatibility: Substitutes are available in 8-SOIC packaging. Two variants exist: standard 8-SOIC (0.154", 3.90mm width) matching the main part's footprint, and 8-SOIC (0.209", 5.30mm width) requiring PCB layout verification.

Electrical Parameters: All substitutes operate within the 2.3V ~ 3.6V supply range and maintain RoHS3 compliance and MSL 3 rating.

Performance Consideration: Substitute parts operate at 133 MHz clock frequency with 800µs write cycle time, exceeding the main part's 80 MHz specification. This represents enhanced performance capability.

Temperature Range Variance: The main part supports -40°C ~ 125°C operation. Substitute parts support -40°C ~ 105°C, representing a 20°C reduction in maximum operating temperature.

Parameter Comparison

Engineering Selection Recommendations

IS25LP016D-JNLE and IS25LP016D-JNLE-TR: These parts provide the closest physical and electrical compatibility with the SST26VF016B-80E/SN. Both maintain the 8-SOIC (0.154", 3.90mm width) footprint, eliminating PCB layout modifications. These variants are suitable for direct substitution in applications where the -40°C ~ 105°C temperature range is acceptable. IS25LP016D-JNLE-TR offers higher inventory availability (30255 units) in cut tape and reel packaging, supporting high-volume production requirements.

IS25LP016D-JBLE: This variant uses an 8-SOIC (0.209", 5.30mm width) package, requiring PCB footprint verification before implementation. Selection of this part necessitates confirmation that the wider package dimensions do not conflict with existing board layout constraints.

Temperature Range Consideration: Applications requiring operation above 105°C must retain the SST26VF016B-80E/SN. Substitute parts are limited to maximum 105°C operation.

Performance Enhancement: All substitute parts deliver 133 MHz clock frequency and 800µs write cycle time, representing performance improvement over the main part's 80 MHz and 1.5ms specifications. Firmware and driver compatibility must be verified to utilize these enhanced capabilities.

Compliance Status: All parts maintain ROHS3 compliance, REACH unaffected status, and identical MSL 3 ratings, ensuring regulatory and environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can IS25LP016D-JBLE be used as a direct replacement for SST26VF016B-80E/SN?

A: IS25LP016D-JBLE is functionally equivalent in memory capacity, interface protocol, and electrical parameters. However, the package width differs (0.209" vs 0.154"), requiring PCB layout verification. If the wider footprint fits within available board space, functional substitution is valid.

Q: What is the primary difference between IS25LP016D-JNLE and IS25LP016D-JNLE-TR?

A: Both parts are electrically and mechanically identical. The difference is packaging format: IS25LP016D-JNLE is supplied in tube packaging, while IS25LP016D-JNLE-TR is supplied in cut tape and Digi-Reel format. Selection depends on production volume and assembly equipment compatibility.

Q: Are the ISSI substitute parts backward compatible with SST26VF016B-80E/SN firmware?

A: The substitute parts support SPI - Quad I/O interface, maintaining protocol compatibility. Extended features (QPI, DTR) are optional and do not affect standard quad I/O operation. Firmware compatibility depends on specific driver implementation and should be verified during integration testing.

Q: What is the impact of the 20°C temperature range reduction in substitute parts?

A: Substitute parts operate to 105°C maximum versus 125°C for the main part. Applications with maximum ambient temperatures below 105°C experience no functional impact. Applications requiring sustained operation above 105°C must use the SST26VF016B-80E/SN.

Q: Do all substitute parts meet the same compliance standards as the main part?

A: Yes. All substitute parts maintain ROHS3 compliance, REACH unaffected status, EAR99 ECCN classification, and identical MSL 3 moisture sensitivity ratings, ensuring regulatory equivalence.

Q: How does the 133 MHz clock frequency of substitute parts affect system design?

A: The higher clock frequency represents enhanced performance capability. Existing firmware designed for 80 MHz operation functions correctly at 133 MHz without modification. System timing margins may improve, but no design changes are required for basic compatibility.
