Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISD4003-06MS is determined by strict equivalence across the following critical parameters:

• Manufacturer & Series: Same manufacturer (Nuvoton Technology Corporation) and ChipCorder® series designation
• Interface Protocol: SPI interface compatibility
• Signal Characteristics: Analog differential input and single-ended output configuration
• Functional Specifications: Identical sampling frequency (5.3kHz), recording duration (6 minutes), filter pass band (2.3kHz), and multiple messaging capability
• Electrical Requirements: Matching supply voltage range (2.7 V ~ 3.3 V) and operating temperature range (0°C ~ 70°C)
• Physical Form Factor: 28-SOIC package with identical dimensions (0.295", 7.50mm Width)
• Environmental Compliance: Equivalent moisture sensitivity level (MSL 3)

The ISD4003-06MSY qualifies as a direct substitute based on complete alignment with all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The ISD4003-06MSY is the direct substitute for the obsolete ISD4003-06MS. Both components share identical functional and electrical specifications, ensuring pin-for-pin and functional compatibility within existing circuit designs.

The primary distinction between these parts is product status and regulatory compliance. The ISD4003-06MSY maintains active production status with ROHS3 compliance, whereas the ISD4003-06MS is obsolete and RoHS non-compliant. For new designs or production continuity, the ISD4003-06MSY is the appropriate selection.

Both components carry equivalent REACH unaffected status and identical environmental ratings (MSL 3). Packaging is available in tube format for the ISD4003-06MSY, supporting standard manufacturing and assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can the ISD4003-06MSY be used as a direct replacement for the ISD4003-06MS in existing designs?

A: Yes. The ISD4003-06MSY is functionally and electrically identical to the ISD4003-06MS across all specified parameters, including interface protocol, signal characteristics, sampling frequency, recording duration, supply voltage, operating temperature range, and package form factor. No circuit modifications are required.

Q: What is the primary reason to transition from ISD4003-06MS to ISD4003-06MSY?

A: The ISD4003-06MS is obsolete, while the ISD4003-06MSY maintains active production status. Additionally, the ISD4003-06MSY is ROHS3 compliant, meeting current regulatory requirements for electronic components in many markets.

Q: Are the 28-SOIC packages identical between these two parts?

A: Yes. Both components use the 28-SOIC package with identical dimensions (0.295", 7.50mm Width). PCB footprints and assembly processes remain unchanged.

Q: What is the moisture sensitivity level for both parts?

A: Both the ISD4003-06MS and ISD4003-06MSY carry an MSL rating of 3 (168 Hours), indicating equivalent moisture handling and storage requirements.

Q: Are there any differences in electrical performance between these substitutes?

A: No. Both parts operate at identical supply voltage (2.7 V ~ 3.3 V), temperature range (0°C ~ 70°C), sampling frequency (5.3kHz), and filter pass band (2.3kHz). Functional performance is equivalent.
