Key Parameters

Substitute Part Grouping Explanation

Substitution for the PCA9534RGVRG4 is determined by strict equivalence across the following critical parameters:

• Base product number (PCA9534 series)
• Number of I/O channels (8-bit)
• Interface protocol (I2C, SMBus at 400 kHz)
• Output configuration (Push-Pull)
• Current drive capability (10mA, 25mA source/sink)
• Supply voltage range (2.3V ~ 5.5V)
• Operating temperature range (-40°C ~ 85°C)
• Package type (16-VQFN Exposed Pad)
• Compliance certifications (ROHS3, REACH Unaffected)

The primary difference between the main part and its substitute lies in packaging format and product status. The PCA9534RGVRG4 uses individual packaging, while the substitute uses Tape & Reel (TR) packaging. Both maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The PCA9534RGVR is the direct functional equivalent to the PCA9534RGVRG4. Both parts maintain identical electrical specifications, interface protocols, and mechanical dimensions. The PCA9534RGVR is currently in active production status, ensuring ongoing availability and supply chain continuity.

Selection between these parts is determined by packaging requirements. The PCA9534RGVR is supplied in Tape & Reel (TR) format, suitable for automated assembly processes and high-volume production. The original PCA9534RGVRG4 was supplied in individual packaging format.

Frequently Asked Questions (FAQ)

Q: Can PCA9534RGVR be used as a direct replacement for PCA9534RGVRG4?

A: Yes. Both parts are electrically and mechanically identical. The PCA9534RGVR provides the same 8-bit I/O expansion, I2C/SMBus interface at 400 kHz, push-pull output configuration, and supply voltage range (2.3V ~ 5.5V). The primary difference is packaging format: PCA9534RGVR uses Tape & Reel (TR) packaging.

Q: What is the difference between individual packaging and Tape & Reel (TR) packaging?

A: Individual packaging supplies components in discrete units, typically for low-volume or prototype applications. Tape & Reel (TR) packaging supplies components on continuous tape within reels, optimized for automated pick-and-place assembly in production environments. Electrical and mechanical specifications remain identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both PCA9534RGVRG4 and PCA9534RGVR maintain identical ROHS3 compliance and REACH Unaffected status. Moisture sensitivity level (MSL 2, 1 Year) is equivalent across both variants.

Q: What determines substitution eligibility for the PCA9534 series?

A: Substitution is based on matching the base product number (PCA9534), I/O count (8-bit), interface protocol (I2C/SMBus at 400 kHz), output type (push-pull), current drive capability (10mA, 25mA), supply voltage range (2.3V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and package type (16-VQFN Exposed Pad).

Q: Is the PCA9534RGVR currently available?

A: Yes. The PCA9534RGVR is in active production status with documented inventory availability, ensuring supply chain reliability for new designs and production requirements.
