Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IDT821034DN is determined by strict equivalence across the following critical parameters:

• Data Interface Type: PCM Audio Interface
• ADC/DAC Configuration: 4 ADCs and 4 DACs
• Supply Voltage Ranges: Analog 4.75V ~ 5.25V; Digital 4.75V ~ 5.25V
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 52-BQFP (52-PQFP 14x14)
• Mounting Technology: Surface Mount

The substitute part 821034DNG meets all these criteria and is manufactured by the same supplier, Renesas Electronics Corporation. The primary distinction is product status and packaging configuration, with the substitute part being active and available in tray packaging.

Engineering Selection Recommendations

The 821034DNG is the direct substitute for the IDT821034DN based on functional and electrical equivalence. Key considerations for component selection:

Product Status: The IDT821034DN is obsolete, while 821034DNG is active and currently manufactured. For new designs or ongoing production, 821034DNG is the appropriate selection to ensure long-term supply availability.

Compliance: The 821034DNG achieves ROHS3 compliance, whereas the IDT821034DN is RoHS non-compliant. This distinction is significant for applications subject to environmental regulations or customer requirements mandating RoHS compliance.

Electrical Equivalence: Both parts maintain identical supply voltage specifications, operating temperature ranges, and ADC/DAC configurations, ensuring direct functional substitution in existing circuit designs without modification.

Packaging: The 821034DNG is supplied in tray packaging, which may differ from the original part's packaging configuration. Verify compatibility with assembly and handling processes.

Frequently Asked Questions (FAQ)

Q: Can 821034DNG be used as a direct replacement for IDT821034DN in existing designs?

A: Yes. The 821034DNG is electrically and functionally equivalent to the IDT821034DN across all critical parameters: PCM audio interface type, 4/4 ADC/DAC configuration, identical supply voltage ranges (4.75V ~ 5.25V), matching operating temperature range (-40°C ~ 85°C), and identical 52-BQFP package. No circuit modifications are required.

Q: What is the primary reason to transition from IDT821034DN to 821034DNG?

A: The IDT821034DN is obsolete and no longer manufactured. The 821034DNG is the active equivalent part from Renesas Electronics Corporation, ensuring continued availability and supply chain support.

Q: Are there compliance differences between these parts?

A: Yes. The 821034DNG is ROHS3 compliant, while the IDT821034DN is RoHS non-compliant. For applications requiring environmental compliance certification, 821034DNG is the appropriate selection.

Q: Do the packaging differences affect circuit board assembly?

A: The 821034DNG is supplied in tray packaging, which may differ from the original part's packaging format. Verify compatibility with your assembly equipment and handling procedures before production transition.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both parts have an MSL rating of 3 (168 Hours), requiring identical storage and handling protocols.
