Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI7C9X760BBLEX is determined by the following critical parameters:

• Functional equivalence: Bridge function converting I2C/SPI protocols to UART
• Package compatibility: 16-TSSOP form factor with identical pin pitch and dimensions
• Voltage supply range: Operating voltage envelope must encompass or match the original specification
• Temperature range: Operating temperature limits must meet or exceed -40°C to 85°C
• Interface protocols: I2C protocol support and UART interface output
• Compliance standards: RoHS3 compliance and REACH unaffected status

The PI7C9X760BCLEX meets all substitution criteria as an active product from the same manufacturer within the same base product family (PI7C9X760), maintaining identical package specifications and functional characteristics.

Parameter Comparison

Engineering Selection Recommendations

The PI7C9X760BCLEX is the direct substitute for the obsolete PI7C9X760BBLEX. Both components share identical functional specifications, package geometry, and thermal operating range. The substitute maintains ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production environments.

The PI7C9X760BCLEX operates across a continuous voltage range of 1.62V to 3.63V, which encompasses the discrete voltage levels (1.8V, 2.5V, 3.3V) specified for the original part. This extended supply voltage specification provides additional design flexibility while maintaining full backward compatibility.

The transition from obsolete to active product status ensures sustained component availability and access to current manufacturing processes and quality assurance protocols.

Frequently Asked Questions (FAQ)

Q: Can the PI7C9X760BCLEX be used as a direct replacement for the PI7C9X760BBLEX?

A: Yes. Both parts share identical package specifications (16-TSSOP), functional characteristics (I2C/SPI to UART bridge), and operating temperature range (-40°C to 85°C). The substitute is manufactured by the same supplier and maintains equivalent compliance certifications.

Q: What is the difference in voltage supply specifications between the two parts?

A: The original part specifies discrete voltage levels (1.8V, 2.5V, 3.3V), while the substitute provides a continuous operating range (1.62V to 3.63V). The substitute range encompasses all original voltage specifications, ensuring compatibility across all intended operating conditions.

Q: Are there any package or pinout differences?

A: No. Both parts use the 16-TSSOP package with identical dimensions (0.173" width, 4.40mm). Pinout and mechanical specifications are equivalent.

Q: Why is the original part classified as obsolete?

A: Product obsolescence typically results from manufacturer lifecycle decisions. The PI7C9X760BCLEX, as an active product within the same base family, provides continuity for ongoing designs and production requirements.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the PI7C9X760BBLEX and PI7C9X760BCLEX are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
