Substitute Part Grouping Explanation

Substitute parts for the TCA9534RGVR are identified based on the following core parameters:

• Number of I/O: 8-bit configuration
• Interface Protocol: I2C compatibility
• Clock Frequency: 400 kHz operation
• Output Type: Push-Pull configuration
• Interrupt Output: Presence of interrupt capability
• Power-On Reset (POR): Feature availability
• RoHS Compliance: ROHS3 Compliant status
• REACH Compliance: REACH Unaffected status

The substitute parts listed maintain functional equivalence through these electrical and compliance parameters, enabling direct substitution in applications where the TCA9534RGVR specifications are met.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full compliance with ROHS3 and REACH requirements, matching the TCA9534RGVR baseline. Selection between the TCA9534RGVR and substitute parts should be based on:

• Packaging availability and PCB layout constraints
• Supply chain inventory levels
• Voltage supply range requirements for specific application operating conditions
• Operating temperature range specifications for target environment
• Current sourcing/sinking capacity requirements

The MAX7324ATG+ and PCA9534BS,118 are electrically equivalent in core I/O expansion functionality, with differences limited to package form factor and secondary electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can MAX7324ATG+ directly replace TCA9534RGVR in all applications?

A: The MAX7324ATG+ shares the same 8-bit I/O count, I2C interface, 400 kHz clock frequency, and push-pull output configuration. Substitution is valid where package compatibility (24-TQFN vs. original package) and voltage/temperature ranges align with application requirements.

Q: What is the primary difference between PCA9534BS,118 and TCA9534RGVR?

A: The PCA9534BS,118 adds SMBus protocol support alongside I2C, operates at a lower maximum temperature (85°C vs. 125°C), and uses a 16-pin package versus the original component's package. The current sourcing/sinking capacity differs at 10mA/25mA versus the original specification.

Q: Are all substitute parts ROHS3 and REACH compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant and REACH Unaffected certifications, matching the compliance profile of the TCA9534RGVR.

Q: What determines if a substitute part is compatible with my design?

A: Compatibility is determined by matching the 8-bit I/O configuration, I2C 400 kHz interface, push-pull output type, interrupt capability, and POR feature. Additionally, verify that the substitute part's voltage supply range, operating temperature range, and package form factor meet your specific application requirements.

Q: Can I use PCA9534BS,118 in applications requiring operation above 85°C?

A: No. The PCA9534BS,118 has a maximum operating temperature of 85°C. Applications requiring operation up to 125°C must use the TCA9534RGVR or MAX7324ATG+, which both support this extended temperature range.
