PCM5102TPWRQ1 Equivalent & Substitute Parts

Part Overview

The PCM5102TPWRQ1 is a 16/24/32-bit audio digital-to-analog converter (DAC) from Texas Instruments, designed for high-resolution audio applications with PCM data interface support. This component operates at sampling rates up to 384 kHz and is packaged in a 20-TSSOP surface mount configuration qualified to automotive standards (AEC-Q100).

The PCM5102TPWRQ1 carries a "Not For New Designs" product status, indicating Texas Instruments has discontinued active development for this variant. Identifying equivalent substitute parts is necessary for ongoing production support, design refreshes, and long-term supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCM5102TPWRQ1 is determined by the following critical parameters:

• Base Product Number: Must be PCM5102 to ensure functional equivalence in audio DAC architecture and pin configuration
• Resolution & Sampling Rate: Must support 16/24/32-bit resolution at 384 kHz sampling rate
• Data Interface: Must use PCM protocol for digital audio input compatibility
• Package / Case: Must be 20-TSSOP with identical 0.173" width and 4.40mm dimensions for PCB layout compatibility
• Mounting Type: Must be Surface Mount for assembly process compatibility
• Grade & Qualification: Must maintain Automotive grade with AEC-Q100 qualification for regulated applications
• Compliance: Must be ROHS3 compliant and maintain MSL 1 rating

The PCM5102AQPWRQ1 qualifies as a direct substitute based on these parameters. While it exhibits differences in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel), supply voltage range (1.65V ~ 3.46V versus 3V ~ 3.6V), and operating temperature upper limit (125°C versus 105°C), these variations represent functional improvements and do not prevent substitution in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The PCM5102AQPWRQ1 is the qualified substitute for the PCM5102TPWRQ1. Both parts maintain identical functional specifications for audio DAC operation, including 2-channel configuration, 16/24/32-bit resolution, 384 kHz sampling rate, and PCM data interface protocol. Both are packaged in 20-TSSOP surface mount format and carry automotive-grade qualification with AEC-Q100 certification and ROHS3 compliance.

The primary distinction is product lifecycle status: the PCM5102TPWRQ1 is designated "Not For New Designs," while the PCM5102AQPWRQ1 maintains "Active" status. The substitute part offers extended operating temperature range (-40°C to 125°C versus -40°C to 105°C) and broader supply voltage tolerance (1.65V to 3.46V versus 3V to 3.6V), representing design improvements without functional degradation.

For applications currently using the PCM5102TPWRQ1, transition to the PCM5102AQPWRQ1 is supported by identical pin configuration, package dimensions, and electrical interface specifications. No circuit redesign is required.

Frequently Asked Questions (FAQ)

Q: Can the PCM5102AQPWRQ1 directly replace the PCM5102TPWRQ1 on existing PCBs?

A: Yes. Both parts use identical 20-TSSOP packaging with matching pin configuration and electrical interface. No PCB layout modifications are necessary.

Q: What is the significance of the "Not For New Designs" status on the PCM5102TPWRQ1?

A: This designation indicates Texas Instruments has concluded active development and support for this specific part variant. The PCM5102AQPWRQ1 represents the current active product line for this audio DAC family.

Q: Are there differences in supply voltage requirements between these parts?

A: The PCM5102TPWRQ1 specifies 3V to 3.6V supply voltage, while the PCM5102AQPWRQ1 accepts 1.65V to 3.46V. The substitute part accommodates a wider voltage range, providing greater design flexibility. Existing designs operating within the 3V to 3.46V window require no modification.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both the PCM5102TPWRQ1 and PCM5102AQPWRQ1 carry Automotive grade classification and AEC-Q100 qualification, suitable for regulated automotive applications.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: These are supply format variations. Tape & Reel (TR) provides continuous reel packaging for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® offers flexible quantity options. Both formats contain identical components; the difference is in delivery and handling method for production environments.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the PCM5102TPWRQ1 and PCM5102AQPWRQ1 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
