PCA8550PWR Equivalent & Substitute Parts

Part Overview

The PCA8550PWR is a 1 x 4:4 multiplexer logic integrated circuit manufactured by Texas Instruments in a 16-TSSOP surface mount package. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity. The PCA8550 series provides single-supply multiplexing functionality with output drive capabilities of 2mA for both high and low states, operating across a 3V to 3.6V supply range.

Substitute Part Grouping Explanation

Substitution of the PCA8550PWR is determined by strict equivalence across the following critical parameters:

• Functional Type: Multiplexer with identical 1 x 4:4 circuit configuration
• Electrical Performance: Output current specifications (2mA high/low), single supply operation, and 3V to 3.6V supply voltage range
• Package Compatibility: 16-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm width)
• Environmental & Compliance: ROHS3 compliance, MSL 1 rating, and REACH unaffected status
• Base Product Number: PCA8550 series designation

The PCA8550PW,118 manufactured by NXP USA Inc. meets all specified parameters and serves as a direct parametric equivalent. The primary distinction is product status: the original part is obsolete while the substitute remains active, and packaging format differs (Tape & Reel versus standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The PCA8550PW,118 from NXP USA Inc. is the appropriate substitute for the obsolete PCA8550PWR. Both components share identical electrical specifications, package geometry, and compliance certifications. The substitute part maintains active product status, ensuring continued availability and supply chain reliability. The Tape & Reel packaging format of the substitute accommodates standard automated assembly processes. Selection of the NXP equivalent eliminates obsolescence risk while preserving full functional and mechanical compatibility within existing designs.

Frequently Asked Questions (FAQ)

Q: Can the PCA8550PW,118 be used as a direct replacement for the PCA8550PWR?

A: Yes. Both parts are parametrically equivalent across all critical specifications: circuit configuration, electrical performance, supply voltage range, output current ratings, operating temperature, and 16-TSSOP package dimensions. The substitute maintains identical functional behavior in circuit applications.

Q: What is the primary difference between these two parts?

A: The PCA8550PWR is classified as obsolete, while the PCA8550PW,118 maintains active product status. Additionally, the substitute is supplied in Tape & Reel packaging format, which is standard for high-volume manufacturing environments.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance, MSL 1 moisture sensitivity rating, and REACH unaffected status. Regulatory and environmental requirements are fully satisfied by either component.

Q: Does the 16-TSSOP package remain the same for both parts?

A: Yes. Both components use the 16-TSSOP package with identical physical dimensions of 0.173" width and 4.40mm overall width, ensuring PCB footprint compatibility.

Q: Are the electrical operating parameters identical?

A: Yes. Supply voltage range (3V to 3.6V), output current specifications (2mA high and low), operating temperature range (0°C to 70°C), and all functional parameters are identical between the two parts.
