Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI7C9X1172BLE is determined by strict alignment of the following critical parameters:

• Base Product Number: PI7C9X1172 (common across main and substitute parts)
• Function: Bridge, I2C/SPI to UART (identical protocol conversion capability)
• Package / Case: 28-TSSOP (0.173", 4.40mm Width) (identical physical footprint and pin configuration)
• Protocol: I2C (identical communication standard)
• Interface: UART (identical output interface)
• RoHS Status: ROHS3 Compliant (identical environmental compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (identical handling requirements)

The PI7C9X1172CLEX qualifies as a direct substitute based on these parameters. The primary distinction is product status: the substitute is active and available, whereas the main part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The PI7C9X1172CLEX is the qualified substitute for the obsolete PI7C9X1172BLE. Both components share identical base product designation, functional capability, package footprint, and compliance certifications. The substitute part is currently in active production status with confirmed inventory availability.

The PI7C9X1172CLEX provides specified operating parameters (voltage range 1.62V ~ 3.63V, current consumption 6mA, operating temperature -40°C ~ 85°C) that encompass the voltage levels supported by the original part. Both components maintain ROHS3 compliance and MSL Level 1 classification, ensuring equivalent environmental and handling requirements.

Selection of the PI7C9X1172CLEX eliminates obsolescence risk while maintaining full functional and physical compatibility with existing designs utilizing the PI7C9X1172BLE.

Frequently Asked Questions (FAQ)

Q: Can the PI7C9X1172CLEX directly replace the PI7C9X1172BLE in existing designs?

A: Yes. Both components share identical base product number, function, protocol support, interface type, and 28-TSSOP package footprint. Pin configuration and electrical interface are equivalent, enabling direct substitution without PCB redesign.

Q: What is the primary reason for substitution?

A: The PI7C9X1172BLE is classified as obsolete. The PI7C9X1172CLEX is an active product with current manufacturing and inventory availability, eliminating supply chain discontinuation risk.

Q: Are the voltage supply specifications compatible?

A: The PI7C9X1172CLEX voltage range (1.62V ~ 3.63V) encompasses the discrete voltage levels supported by the PI7C9X1172BLE (1.8V, 2.5V, 3.3V). The substitute part operates across a continuous voltage range that includes all specified operating points of the original component.

Q: What is the difference in packaging between these parts?

A: The PI7C9X1172BLE packaging format is not specified in available data. The PI7C9X1172CLEX is supplied in Tape & Reel (TR) format, which is standard for high-volume production and automated assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PI7C9X1172BLE and PI7C9X1172CLEX are ROHS3 compliant and classified as REACH Unaffected. Both components carry MSL Level 1 (Unlimited) moisture sensitivity classification.

Q: Is the I2C/SPI to UART bridge functionality identical?

A: Yes. Both components perform identical protocol bridge functions, converting I2C/SPI communication to UART interface. The functional specification and interface capability are equivalent.
