Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCA9665D,112 is determined by the following critical parameters:

Functional Equivalence Criteria:

• Protocol: I2C
• Function: Controller
• Interface Type: Parallel
• Voltage - Supply: 2.3V ~ 3.6V
• Current - Supply: 100µA
• Operating Temperature: -40°C ~ 85°C
• Base Product Number: PCA9665

Compliance & Regulatory Criteria:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The PCA9665PW,118 qualifies as a manufacturer-recommended substitute because it maintains identical electrical specifications, operational parameters, and regulatory compliance while differing only in package configuration and product status.

Parameter Comparison

Engineering Selection Recommendations

The PCA9665PW,118 is the manufacturer-recommended substitute for the obsolete PCA9665D,112. Both components share identical electrical specifications, operational parameters, and regulatory compliance certifications (ROHS3 Compliant, REACH Unaffected, MSL 1).

The primary distinction between these parts is packaging: the PCA9665D,112 uses a 20-SOIC package, while the PCA9665PW,118 uses a 20-TSSOP package. The PCA9665PW,118 maintains Active product status, ensuring ongoing availability and supply chain support.

Selection of the PCA9665PW,118 requires PCB layout modification to accommodate the different package footprint. Pin configuration and electrical functionality remain equivalent, supporting direct functional replacement within systems designed for the PCA9665 controller series.

Frequently Asked Questions (FAQ)

Q: Can the PCA9665PW,118 directly replace the PCA9665D,112 without design changes?

A: Electrical and functional replacement is direct. PCB layout modification is required due to package differences: 20-SOIC versus 20-TSSOP. Pin assignments and electrical specifications are identical.

Q: What is the primary reason for substitution?

A: The PCA9665D,112 is Obsolete. The PCA9665PW,118 is Active and maintains full supply availability.

Q: Are compliance certifications identical between these parts?

A: Yes. Both components are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What are the package dimension differences?

A: The PCA9665D,112 uses 20-SOIC (0.295", 7.50mm Width). The PCA9665PW,118 uses 20-TSSOP (0.173", 4.40mm Width). The TSSOP package is narrower, requiring PCB footprint redesign.

Q: Are the supply voltage and operating temperature ranges the same?

A: Yes. Both parts operate at 2.3V to 3.6V supply voltage and -40°C to 85°C operating temperature with 100µA supply current.

Q: Is the PCA9665PW,118 available in Tape & Reel packaging?

A: Yes. The PCA9665PW,118 is supplied in Tape & Reel (TR) packaging format.
