SST26VF032BT-104V/MF Equivalent & Substitute Parts

Part Overview

The SST26VF032BT-104V/MF is a 32Mbit SPI/Quad I/O Flash memory IC manufactured by Microchip Technology in an 8-WDFN (5x6) surface mount package. This non-volatile memory device operates at 104 MHz and is designed for embedded systems requiring high-density flash storage with quad I/O interface capability. The part is currently in active production status with full RoHS3 compliance and REACH unaffected certification. Substitute parts are identified when equivalent memory capacity, interface protocol, voltage specifications, and thermal operating range align with application requirements while maintaining package compatibility or acceptable form factor variations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SST26VF032BT-104V/MF are qualified based on the following criteria:

Core Electrical Parameters (Must Match):

• Memory capacity: 32Mbit
• Memory organization: 4M x 8
• Memory interface: SPI - Quad I/O support
• Voltage supply range: Compatible with 2.7V ~ 3.6V (substitute range 2.3V ~ 3.6V is acceptable as it encompasses the main part specification)
• Operating temperature range: -40°C ~ 105°C
• Non-volatile FLASH memory technology

Mechanical Parameters (Acceptable Variation):

• Package type: 8-pin WDFN/WSON with exposed pad (minor footprint variations acceptable: 5x6mm vs 6x5mm vs 8x6mm)
• Surface mount mounting type

Performance Parameters (Enhancement Acceptable):

• Clock frequency: 133 MHz (substitute) exceeds 104 MHz (main part) requirement
• Write cycle time: 800µs (substitute) is faster than 1.5ms (main part)

Compliance Parameters (Must Match):

• RoHS3 compliance
• REACH unaffected status
• MSL rating 3 (168 Hours)

The identified substitutes (IS25LP032D-JKLE and IS25LP032D-JLLE) meet all core electrical requirements and compliance standards. Both parts are manufactured by ISSI (Integrated Silicon Solution Inc) and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

Both IS25LP032D-JKLE and IS25LP032D-JLLE are qualified substitutes for the SST26VF032BT-104V/MF based on electrical equivalence and compliance certification alignment.

IS25LP032D-JKLE (6x5mm package): This substitute maintains the closest physical footprint to the main part (5x6mm vs 6x5mm), representing a minimal PCB layout adjustment. The part is available in higher inventory (1850 pcs) and provides enhanced performance specifications including 133 MHz clock frequency and 800µs write cycle time.

IS25LP032D-JLLE (8x6mm package): This substitute features a larger footprint (8x6mm) compared to the main part. Selection of this variant requires PCB layout modification to accommodate the increased package dimensions. Inventory availability is higher (2300 pcs). Performance specifications match IS25LP032D-JKLE.

Both substitutes support extended interface capabilities (QPI and DTR modes) beyond the base SPI - Quad I/O requirement, offering additional flexibility for advanced application implementations. All three parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL rating 3 certification.

Frequently Asked Questions (FAQ)

Q: Can IS25LP032D-JKLE and IS25LP032D-JLLE be used interchangeably with SST26VF032BT-104V/MF?

A: Both ISSI parts are electrically equivalent to the Microchip part for core memory functionality. The primary difference is package footprint. IS25LP032D-JKLE (6x5mm) requires minimal PCB layout adjustment. IS25LP032D-JLLE (8x6mm) requires more significant layout modification. Both maintain identical electrical specifications, voltage ranges, temperature ratings, and compliance certifications.

Q: What is the difference between the two ISSI substitute parts?

A: IS25LP032D-JKLE and IS25LP032D-JLLE differ only in package dimensions. IS25LP032D-JKLE uses an 8-WSON (6x5mm) package. IS25LP032D-JLLE uses an 8-WSON (8x6mm) package. All electrical specifications, memory capacity, interface protocols, and performance characteristics are identical between the two variants.

Q: Are the substitute parts pin-compatible with the main part?

A: All three parts use 8-pin WDFN/WSON packages with exposed pad and maintain identical pin assignments for SPI - Quad I/O interface operation. Pin compatibility is confirmed. Physical footprint differences require PCB layout verification.

Q: Do the substitute parts support the same voltage supply range?

A: The substitute parts support 2.3V ~ 3.6V, which encompasses the main part specification of 2.7V ~ 3.6V. Applications designed for 2.7V ~ 3.6V operation are fully compatible with the substitute parts.

Q: What are the performance advantages of the substitute parts?

A: The ISSI substitutes provide 133 MHz clock frequency (vs 104 MHz main part) and 800µs write cycle time (vs 1.5ms main part), representing 28% higher clock speed and 47% faster write performance. Both parts support additional interface modes (QPI and DTR) not specified in the main part.

Q: Are compliance certifications identical across all three parts?

A: Yes. All three parts maintain ROHS3 compliance, REACH unaffected status, MSL rating 3 (168 Hours), and active product status. Compliance certifications are equivalent.
