Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISD4004-12MP 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
• Functional Specifications: 5.3 kHz sampling frequency, 12-minute duration, 2.3 kHz filter pass band, multiple messaging capability
• Oscillator Configuration: Internal/External capability
• Package Specification: 28-DIP through-hole mounting
• Electrical Ratings: 2.7 V ~ 3.3 V supply voltage, 0°C ~ 70°C operating temperature range

The ISD4004-12MPY meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The ISD4004-12MPY is the direct substitute for the ISD4004-12MP. Both components share identical functional and electrical specifications, package configuration, and interface characteristics.

The ISD4004-12MPY offers additional advantages for new designs and system updates:

• Product Status: Active production status ensures long-term availability and supply chain stability
• RoHS Compliance: ROHS3 compliant, meeting current environmental and regulatory requirements
• Moisture Sensitivity: MSL 1 rating provides superior moisture tolerance compared to the MSL 3 rating of the original part

For legacy system maintenance where the original ISD4004-12MP is required, the ISD4004-12MPY provides functional equivalence with improved compliance and reliability characteristics.

Frequently Asked Questions (FAQ)

Q: Can the ISD4004-12MPY be used as a direct replacement for the ISD4004-12MP in existing designs?

A: Yes. The ISD4004-12MPY is functionally and electrically equivalent to the ISD4004-12MP. Both components feature identical SPI interface, signal characteristics, sampling frequency, recording duration, and package configuration. No circuit modifications are required.

Q: What is the difference between the ISD4004-12MP and ISD4004-12MPY?

A: The primary differences are product status, packaging format, and compliance ratings. The ISD4004-12MPY is in active production, supplied in tube packaging, and meets ROHS3 compliance with MSL 1 moisture sensitivity. The ISD4004-12MP is obsolete with MSL 3 moisture sensitivity and RoHS non-compliant status.

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

A: No. Both parts use the 28-DIP package with identical pin assignments and through-hole mounting specifications.

Q: What packaging options are available for the ISD4004-12MPY?

A: The ISD4004-12MPY is supplied in tube packaging format.

Q: Do both parts support the same supply voltage range?

A: Yes. Both the ISD4004-12MP and ISD4004-12MPY operate within the 2.7 V ~ 3.3 V supply voltage range and share identical operating temperature specifications of 0°C ~ 70°C.
