Substitute Part Grouping Explanation

Substitution of the PCM3002EG/2K is determined by strict equivalence across the following critical parameters:

• Data Interface: Serial
• Resolution: 20-bit
• ADC/DAC Configuration: 2 / 2
• Sigma-Delta Architecture: Yes
• S/N Ratio (ADCs / DACs): 90 / 94 dB
• Dynamic Range (ADCs / DACs): 90 / 94 dB
• Analog Supply Voltage: 2.7V ~ 3.6V
• Digital Supply Voltage: 2.7V ~ 3.6V
• Operating Temperature Range: -25°C ~ 85°C
• Package Type: 24-SSOP
• Physical Dimensions: 0.209" × 5.30mm Width

The PCM3003E/2K meets all these electrical and mechanical specifications, establishing it as a direct functional equivalent. The primary distinction is product status: PCM3003E/2K is active and available, whereas PCM3002EG/2K is obsolete.

Parameter Comparison

Engineering Selection Recommendations

Frequently Asked Questions (FAQ)

Q: Can PCM3003E/2K be used as a direct replacement for PCM3002EG/2K?

A: Yes. Both components are electrically and mechanically equivalent. The PCM3003E/2K provides identical serial data interface, 20-bit resolution, dual ADC/DAC configuration, and signal-to-noise specifications. Pin configuration and package footprint are identical, supporting direct substitution in existing PCB designs.

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

A: The PCM3002EG/2K is obsolete, while PCM3003E/2K is active. Additionally, PCM3003E/2K features improved moisture sensitivity (MSL 1 vs. MSL 2) and is supplied in Tape & Reel format rather than bulk packaging.

Q: Are there any supply voltage or temperature range differences?

A: No. Both components operate across identical analog and digital supply voltage ranges (2.7V to 3.6V) and the same operating temperature range (-25°C to 85°C).

Q: Does the package type affect compatibility?

A: No. Both components use the 24-SSOP package with identical physical dimensions (0.209" × 5.30mm Width). The difference in packaging format (Tape & Reel vs. bulk) relates to delivery and handling, not electrical or mechanical compatibility.

Q: Are compliance certifications equivalent?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting the same regulatory requirements for electronic component manufacturing and use.
