PCM4202DBRG4 Equivalent & Substitute Parts

Part Overview

The PCM4202DBRG4 is a 24-bit audio analog-to-digital converter (ADC) manufactured by Texas Instruments, designed for audio data acquisition applications. It features dual-channel conversion with a 216 kHz sampling rate and supports both DSP and PCM data interfaces. The device operates from 1.65V to 3.6V and 5V supply rails, making it suitable for mixed-signal audio processing systems.

The PCM4202DBRG4 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCM4202DBRG4 is determined by the following critical parameters:

• Channel Configuration: 2-channel audio ADC
• Resolution: 24-bit conversion
• Sampling Rate: 216 kHz maximum
• Data Interface: DSP and PCM protocol support
• Supply Voltage: Dual supply rails (1.65V ~ 3.6V and 5V)
• Package: 28-SSOP surface mount form factor
• Thermal Range: -10°C ~ 70°C operating window
• Compliance: ROHS3 and REACH requirements

The PCM4202DBR meets all these criteria and is identified as the manufacturer-recommended substitute. Both parts share identical electrical specifications, interface protocols, and physical packaging, enabling direct substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The PCM4202DBR is the direct substitute for the PCM4202DBRG4. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications across all functional parameters. The primary distinction is product status: the PCM4202DBRG4 is discontinued, while the PCM4202DBR maintains active production status with significantly higher inventory availability (55,400 units versus 940 units).

From a compliance perspective, both parts meet ROHS3 and REACH requirements, ensuring regulatory alignment for new designs and production continuity. The PCM4202DBR is available in standard packaging formats (Cut Tape and Digi-Reel), supporting both prototype and volume manufacturing workflows.

Frequently Asked Questions (FAQ)

Q: Can the PCM4202DBR directly replace the PCM4202DBRG4 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. No circuit modifications, firmware changes, or PCB layout adjustments are required. Pin configuration, signal timing, and interface protocols are identical.

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

A: No. Both the PCM4202DBRG4 and PCM4202DBR operate from identical dual supply rails: 1.65V to 3.6V and 5V. Power distribution and decoupling schemes remain unchanged.

Q: What is the significance of the packaging designation difference (DBRG4 versus DBR)?

A: The suffix designates the supplier packaging format. DBRG4 indicates Digi-Reel packaging, while DBR is available in both Cut Tape and Digi-Reel formats. The die, package type (28-SSOP), and electrical performance are identical.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -10°C to 70°C. Thermal management and derating calculations remain consistent.

Q: What compliance certifications apply to the PCM4202DBR?

A: The PCM4202DBR maintains ROHS3 compliance and is REACH unaffected, matching the regulatory status of the discontinued PCM4202DBRG4.

Q: Is the PCM4202DBR available in sufficient quantities for production?

A: Yes. The PCM4202DBR has 55,400 units in stock, providing adequate supply for both prototype development and volume manufacturing compared to the limited remaining inventory of the discontinued variant.
