Substitute Part Grouping Explanation

Substitution of the PCM3168APAPRG4 is determined by strict equivalence across the following critical parameters:

• Resolution and Channel Configuration: 24-bit resolution with 6 ADCs and 8 DACs
• Data Interface: Serial interface requirement
• Sigma-Delta Architecture: Presence of Sigma-Delta modulation
• Signal Quality Metrics: S/N ratio and dynamic range specifications (107/112 dB differential, 104/112 dB single-ended)
• Power Supply Voltages: Analog supply 4.5V ~ 5.5V and digital supply 3V ~ 3.6V
• Operating Temperature Range: -40°C ~ 85°C
• Package Specification: 64-HTQFP (10x10) form factor
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected status

The PCM3168APAPR qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is packaging format and product availability status.

Parameter Comparison

Engineering Selection Recommendations

The PCM3168APAPR is a direct functional and electrical equivalent to the PCM3168APAPRG4. Selection between these parts is determined by supply chain and packaging requirements:

PCM3168APAPRG4 (Original): Use when existing inventory is available and tube packaging is acceptable for current production requirements. Product status is discontinued, limiting future availability.

PCM3168APAPR (Substitute): Use for new production runs and ongoing system support. This part maintains active product status with significantly higher inventory availability (35300 pcs vs. 919 pcs). Packaging is supplied in Cut Tape and Digi-Reel formats, suitable for automated assembly processes.

Both parts satisfy identical electrical specifications, regulatory compliance requirements (ROHS3, REACH), and thermal operating ranges. No circuit redesign or firmware modification is required when transitioning between these parts.

Frequently Asked Questions (FAQ)

Q: Are PCM3168APAPRG4 and PCM3168APAPR pin-compatible?

A: Yes. Both parts use the 64-HTQFP (10x10) package with identical pinout, electrical characteristics, and functional specifications. Direct PCB substitution is possible without layout modifications.

Q: What is the difference between the part numbers?

A: The suffix "G4" in PCM3168APAPRG4 indicates the original tube packaging format. PCM3168APAPR uses the same die and specifications but is supplied in Cut Tape and Digi-Reel packaging formats. The base product number PCM3168 remains identical.

Q: Can I use PCM3168APAPR in designs currently specified for PCM3168APAPRG4?

A: Yes. Electrical and functional equivalence is complete. Verify that your assembly process accommodates the Cut Tape or Digi-Reel packaging format. No circuit modifications are required.

Q: What are the power supply requirements for both parts?

A: Both parts require dual supply voltages: analog supply 4.5V ~ 5.5V and digital supply 3V ~ 3.6V. Decoupling and filtering recommendations from the Texas Instruments datasheet apply equally to both parts.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 Compliant and REACH Unaffected. Moisture sensitivity level (MSL 3, 168 hours) and handling requirements are identical.

Q: Why is PCM3168APAPRG4 discontinued?

A: Product discontinuation at DiGi Electronics reflects supply chain consolidation toward the PCM3168APAPR variant. The active substitute provides superior inventory availability and supports ongoing production requirements.

Q: What is the lead time for PCM3168APAPR?

A: Lead time information is not provided in the technical specifications. Contact your authorized Texas Instruments distributor for current availability and delivery schedules.
