Substitute Part Grouping Explanation

Substitution of the ISD4003-06MP is determined by strict equivalence across the following critical parameters:

• Manufacturer & Series: Nuvoton Technology Corporation ChipCorder® series
• Interface Protocol: SPI
• Signal Characteristics: Analog differential input, analog single-ended output
• Audio Specifications: 5.3 kHz sampling frequency, 6-minute duration, 2.3 kHz filter pass band
• Messaging Architecture: Multiple message support
• Oscillator Configuration: Internal/External capability
• Electrical Specifications: 2.7 V ~ 3.3 V supply voltage, 0°C ~ 70°C operating range
• Physical Form Factor: 28-DIP through-hole package (0.600", 15.24mm)

The ISD4003-06MPY maintains complete electrical and mechanical compatibility with the ISD4003-06MP across all specified parameters, with the primary distinction being product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The ISD4003-06MPY is the direct substitute for the obsolete ISD4003-06MP. Both devices share identical electrical specifications, signal characteristics, and physical form factors, ensuring pin-for-pin and functional compatibility in existing circuit designs.

The ISD4003-06MPY offers the advantage of active product status, ensuring continued availability and manufacturer support. Additionally, the ISD4003-06MPY achieves ROHS3 compliance, whereas the ISD4003-06MP is RoHS non-compliant. For new designs or systems requiring regulatory compliance with current environmental standards, the ISD4003-06MPY is the appropriate selection.

Both devices maintain REACH Unaffected status. The packaging difference (tube format for ISD4003-06MPY versus standard packaging for ISD4003-06MP) does not affect electrical or mechanical compatibility and relates only to supply chain and handling considerations.

Frequently Asked Questions (FAQ)

Q: Can the ISD4003-06MPY directly replace the ISD4003-06MP in existing designs?

A: Yes. The ISD4003-06MPY maintains complete electrical and mechanical compatibility with the ISD4003-06MP. All interface protocols, signal characteristics, voltage specifications, temperature ratings, and package dimensions are identical. No circuit modifications are required.

Q: What is the significance of the product status difference between these parts?

A: The ISD4003-06MP is classified as obsolete, indicating discontinued manufacturing and limited availability. The ISD4003-06MPY is active, ensuring ongoing production, availability, and manufacturer technical support. For new applications or replacement inventory, the active part is the appropriate choice.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance status does not affect electrical or functional compatibility. The difference reflects manufacturing process and material composition. Selection between RoHS-compliant and non-compliant versions depends on regulatory requirements for your specific application and market.

Q: What is the impact of the packaging format difference?

A: Packaging format (tube versus standard) affects only supply chain logistics, handling, and storage. It does not impact electrical performance, pin configuration, or mechanical fit. Both formats contain identical die and internal circuitry.

Q: Are there any pin configuration differences between these parts?

A: No. Both the ISD4003-06MP and ISD4003-06MPY use the 28-DIP package with identical pin assignments, signal routing, and functional pin definitions. Direct socket substitution is possible.

Q: What are the critical parameters for ensuring substitution compatibility?

A: Substitution compatibility is determined by: SPI interface protocol, differential analog input with single-ended analog output, 5.3 kHz sampling frequency, 6-minute recording duration, 2.3 kHz filter pass band, multiple message capability, 2.7 V ~ 3.3 V supply voltage range, 0°C ~ 70°C operating temperature, and 28-DIP through-hole package form factor.
