PCA9560PW,112 Equivalent & Substitute Parts

Part Overview

The PCA9560PW,112 is a specialized network and telecom interface IC manufactured by NXP USA Inc., designed for I2C and SMBus communication protocols. This 20-TSSOP surface mount component operates within a supply voltage range of 3.135V to 3.465V and is classified as obsolete. Due to its obsolete product status, identifying functionally equivalent substitute parts is essential for ongoing system maintenance, redesigns, and new production implementations where this interface functionality remains required.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PCA9560PW,112 is determined by the following critical parameters:

• Interface Protocol Compatibility: Primary substitutes must support I2C and/or SMBus communication protocols
• Supply Voltage Range: Substitute parts must operate within or encompass the 3.135V to 3.465V range, or provide compatible voltage regulation
• Package Form Factor: Surface mount packages with similar pin counts and footprints (20-TSSOP preferred for direct replacement)
• Product Status: Active or Last Time Buy status preferred over obsolete classifications
• Compliance Standards: RoHS3 compliance and REACH unaffected status maintained across substitutes

The identified substitute parts are grouped by their primary functional application while maintaining these core compatibility criteria.

Parameter Comparison

Engineering Selection Recommendations

LTC4306IGN#TRPBF (Analog Devices Inc.) provides the closest functional alignment for I2C/SMBus applications. This part maintains 20-TSSOP package compatibility, operates across an extended voltage range (2.2V to 5.5V) that encompasses the original specification, and holds Active product status with unlimited MSL rating. The 24-SSOP package requires PCB layout adjustment but preserves pin-level compatibility for multiplexer and amplifier interface functions.

ADP5586ACBZ-03-R7 (Analog Devices Inc.) serves applications requiring I2C keypad entry and I/O expansion functionality. While the 16-WLCSP package differs significantly from the original 20-TSSOP form factor, this part maintains Active status, operates within the required voltage envelope (1.65V to 3.6V), and provides unlimited MSL rating. This substitute requires substantial PCB redesign.

PI4MSD5V9545BLEX (Diodes Incorporated) offers bus switching functionality in the original 20-TSSOP package. This part maintains direct package compatibility, operates across 1.65V to 5.5V supply range, and holds Active status with unlimited MSL rating. Selection of this substitute depends on application requirements for bus switching versus the original interface specialization.

DS125DF111SQE (Texas Instruments) addresses signal retimer applications with Serial interface capability. This part operates at 2.5V and 3.3V supply levels, maintains Active status, but requires MSL 3 handling (168 hours) and package conversion to 24-WFQFN.

Z8523316ASG (Zilog) represents a Last Time Buy option with 44-LQFP package configuration. This part operates at 4.5V to 5.5V supply range, requiring voltage regulation if the original 3.135V to 3.465V specification is mandatory. MSL 3 rating (168 hours) applies.

Frequently Asked Questions (FAQ)

Q: Can LTC4306IGN#TRPBF directly replace PCA9560PW,112 without PCB modification?

A: LTC4306IGN#TRPBF maintains the same 20-TSSOP package footprint and pin count, enabling direct PCB placement. However, the 24-SSOP package variant requires verification of pin assignment compatibility and signal routing before implementation.

Q: What is the primary reason for substitution?

A: The PCA9560PW,112 is classified as obsolete. Substitute parts with Active or Last Time Buy status ensure long-term component availability and supply chain continuity.

Q: Does ADP5586ACBZ-03-R7 require circuit redesign?

A: Yes. The 16-WLCSP package (1.59x1.59mm) differs substantially from the original 20-TSSOP form factor. PCB layout, via placement, and signal routing require complete redesign. Pin assignment verification is mandatory.

Q: Which substitute maintains the lowest MSL rating?

A: LTC4306IGN#TRPBF, ADP5586ACBZ-03-R7, and PI4MSD5V9545BLEX all maintain MSL 1 (Unlimited) rating, matching the original part specification. DS125DF111SQE and Z8523316ASG require MSL 3 handling (168 hours).

Q: Are all substitutes RoHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original PCA9560PW,112 specification.

Q: What voltage regulation is required for Z8523316ASG?

A: Z8523316ASG operates at 4.5V to 5.5V supply range. If the original 3.135V to 3.465V specification is mandatory, external voltage regulation or a different substitute selection is required.

Q: Can PI4MSD5V9545BLEX replace the original part in all applications?

A: PI4MSD5V9545BLEX provides bus switching functionality (2 x 1:4 configuration) in the original 20-TSSOP package. Substitution is valid only for applications where bus switching meets functional requirements. Verify that the original PCA9560PW,112 application does not require specialized interface functions beyond bus switching capability.
