Key Parameters

Substitute Part Grouping Explanation

Substitution for the PCA9560D,112 is determined by the following critical parameters:

Primary Substitution Criteria:

• Interface protocol compatibility (I2C, SMBus, or equivalent bus interface)
• Supply voltage range overlap or compatibility with 3V to 3.6V operation
• Package type and pin count (20-pin configuration preferred for direct replacement)
• Application domain (Network, Telecom, or Controller interface)
• RoHS3 compliance and MSL rating
• Product status (Active preferred for long-term availability)

Substitute Parts Identified:

1. PCA9560PW,118 (NXP USA Inc.) – Direct family equivalent with same base product number (PCA9560), same interface protocols, active status, and ROHS3 compliance. Package differs (20-TSSOP vs. 20-SOIC) but maintains 20-pin configuration.

2. MAX7359ETG+T (Analog Devices Inc./Maxim Integrated) – I2C interface specialist for consumer electronics and telecom applications, 24-pin TQFN package, active status, ROHS3 compliant, voltage range 1.65V to 3.6V overlaps with PCA9560D supply requirements.

3. MAX1840EUB+T (Analog Devices Inc./Maxim Integrated) – Multi-protocol interface IC (MICROWIRE, QSPI, Serial, SPI) with broad voltage support (1.4V to 5.5V), active status, ROHS3 compliant, suitable for smart card and telecom interface applications.

4. FPC401RHUT (Texas Instruments) – I2C controller interface in 56-WQFN package, active status, voltage range 1.8V to 3.3V, ROHS3 compliant, MSL 2 rating, designed for controller applications.

5. AD7669ARZ-REEL (Analog Devices Inc.) – Analog I/O interface IC in 28-SOIC package, active status, ROHS3 compliant, operates at 4.75V to 5.25V, suitable for analog interface applications in network systems.

6. MAX35103EHJ+ (Analog Devices Inc./Maxim Integrated) – Time-to-digital converter with integrated analog front-end in 32-TQFP package, active status, ROHS3 compliant, designed for specialized interface and measurement applications.

Engineering Selection Recommendations

Primary Recommendation: PCA9560PW,118

The PCA9560PW,118 is the preferred substitute for the obsolete PCA9560D,112. Both parts share the same base product number (PCA9560), identical interface protocols (I2C, SMBus), and application domain (Network, Telecom). The PCA9560PW,118 maintains active product status, ensuring long-term availability and supply chain continuity. Supply voltage range (3.135V to 3.465V) is compatible with the original part's 3V to 3.6V specification. Both components are ROHS3 compliant with MSL 1 rating. The primary difference is package type: PCA9560PW,118 uses 20-TSSOP versus the original 20-SOIC, but both maintain 20-pin configuration and surface mount technology.

Secondary Recommendations by Application:

For I2C-specific applications in consumer electronics and telecom: MAX7359ETG+T provides active status, ROHS3 compliance, and voltage range (1.65V to 3.6V) that encompasses the original specification. The 24-TQFN package offers compact form factor.

For multi-protocol interface requirements: MAX1840EUB+T supports MICROWIRE, QSPI, Serial, and SPI protocols with broad voltage tolerance (1.4V to 5.5V), active status, and ROHS3 compliance.

For controller-based applications: FPC401RHUT offers I2C interface in 56-WQFN package with active status and ROHS3 compliance, though MSL rating is 2 (1 Year) versus the original MSL 1.

All substitute parts maintain ROHS3 compliance and active product status, ensuring regulatory compliance and supply availability for new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can PCA9560PW,118 directly replace PCA9560D,112 in existing designs?

A: PCA9560PW,118 is functionally equivalent with identical interface protocols and application domain. The primary design consideration is package type: PCA9560PW,118 uses 20-TSSOP (0.173", 4.40mm width) versus the original 20-SOIC (0.295", 7.50mm width). PCB layout and footprint must be updated accordingly. Pin configuration and electrical characteristics are compatible within the specified voltage ranges.

Q: What is the voltage compatibility between PCA9560D,112 and its substitutes?

A: The original PCA9560D,112 operates at 3V to 3.6V. PCA9560PW,118 operates at 3.135V to 3.465V, providing direct compatibility. MAX7359ETG+T (1.65V to 3.6V) and FPC401RHUT (1.8V to 3.3V) both support the original voltage range. MAX1840EUB+T (1.4V to 5.5V) and AD7669ARZ-REEL (4.75V to 5.25V) have different voltage requirements and require circuit design evaluation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts—PCA9560PW,118, MAX7359ETG+T, MAX1840EUB+T, FPC401RHUT, AD7669ARZ-REEL, and MAX35103EHJ+—are ROHS3 compliant, matching the original PCA9560D,112 compliance status.

Q: What is the difference between MSL 1 and MSL 2 ratings?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life under controlled storage conditions. MSL 2 (1 Year) indicates a one-year maximum shelf life. FPC401RHUT carries MSL 2 rating, requiring stricter inventory management compared to the original MSL 1 rating. All other substitutes maintain MSL 1 rating.

Q: Which substitute is best for new network and telecom designs?

A: PCA9560PW,118 is the recommended choice for new network and telecom designs, as it maintains the same base product family, interface protocols, and application domain as the original PCA9560D,112. Active product status ensures long-term availability and manufacturer support.

Q: Can MAX1840EUB+T replace PCA9560D,112 in I2C/SMBus applications?

A: MAX1840EUB+T supports multiple protocols including SPI and QSPI but is primarily designed for smart card interface applications. While it includes serial interface capability, it is not optimized for I2C/SMBus-specific network and telecom applications. PCA9560PW,118 or MAX7359ETG+T are more appropriate for I2C/SMBus requirements.

Q: What package considerations apply when selecting a substitute?

A: Package type affects PCB layout, thermal management, and board space. PCA9560PW,118 (20-TSSOP) is the most compact direct replacement. MAX7359ETG+T (24-TQFN) and FPC401RHUT (56-WQFN) require larger board footprints. AD7669ARZ-REEL (28-SOIC) and MAX35103EHJ+ (32-TQFP) offer different form factors. Verify PCB design compatibility before component selection.
