Parameter Comparison

Engineering Selection Recommendations

The ISD4003-08MPY is the direct substitute for the ISD4003-08MP. Both components share identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and functional equivalence in circuit applications.

The ISD4003-08MPY offers two significant advantages over the original part:

Product Status: The ISD4003-08MPY maintains Active product status, ensuring continued availability and manufacturer support. The ISD4003-08MP is classified as Obsolete, limiting future procurement options.

Compliance Certification: The ISD4003-08MPY is ROHS3 Compliant, meeting current environmental and hazardous substance restrictions. The ISD4003-08MP is RoHS non-compliant, which may present regulatory constraints in certain applications and markets.

Both components maintain identical REACH Unaffected and EAR99 export classification status.

Frequently Asked Questions (FAQ)

Q: Are the ISD4003-08MP and ISD4003-08MPY pin-compatible?

A: Yes. Both components use the 28-DIP (0.600", 15.24mm) package with identical pinout. Direct board-level substitution is possible without circuit modification.

Q: What are the key electrical differences between these parts?

A: There are no electrical differences. Both parts maintain identical SPI interface protocol, 4kHz sampling frequency, 8-minute recording duration, 1.7kHz filter pass band, differential analog input, single-ended analog output, and 2.7V to 3.3V supply voltage range.

Q: Why is the ISD4003-08MP listed as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this part number. The ISD4003-08MPY represents the current active equivalent.

Q: Does RoHS3 compliance affect circuit performance?

A: No. RoHS3 compliance reflects manufacturing process changes to eliminate hazardous substances. Electrical and functional performance remains identical to the non-compliant version.

Q: Can I use the ISD4003-08MPY in existing designs originally specified for the ISD4003-08MP?

A: Yes. Identical electrical specifications, pin configuration, and package dimensions ensure direct functional replacement without design modification.

Q: What is the packaging difference between these parts?

A: The ISD4003-08MP packaging is unspecified in the original documentation. The ISD4003-08MPY is supplied in Tube packaging. Both use the same 28-DIP physical package format.
