Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISD5102SYR is determined by strict equivalence across the following critical parameters:

• Manufacturer & Series: Same manufacturer (Nuvoton Technology Corporation) and ChipCorder® series designation
• Interface Protocol: I2C interface compatibility
• Package & Mounting: Identical 28-SOIC surface mount package
• Signal Specifications: Matching input (analog microphone) and output (analog single-ended, analog differential, PWM speaker) configurations
• Functional Specifications: Equivalent sampling frequency (4 ~ 8kHz), duration capacity (1 Min 5 Sec ~ 2 Min 11 Sec), and filter pass band (1.7 ~ 3.4kHz)
• Electrical Characteristics: Identical supply voltage range (2.7 V ~ 3.3 V) and operating temperature range (0°C ~ 70°C)
• Messaging Capability: Multiple message support
• Oscillator Configuration: Internal/External oscillator support

The ISD5102SY meets all substitution criteria and is classified as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The ISD5102SY is the direct substitute for the ISD5102SYR. Both parts are manufactured by Nuvoton Technology Corporation and share identical electrical, functional, and mechanical specifications. The primary distinction is product status: the ISD5102SYR is obsolete, while the ISD5102SY maintains active production status.

The ISD5102SY offers additional compliance advantage through ROHS3 certification, meeting current environmental and regulatory requirements. Packaging differs between the two parts (tube versus reel), which may affect procurement and assembly processes but does not impact electrical or functional compatibility.

For new designs or applications requiring long-term component availability, the ISD5102SY is the appropriate selection. For existing designs currently using the ISD5102SYR, direct substitution with the ISD5102SY is electrically and mechanically valid.

Frequently Asked Questions (FAQ)

Q: Can the ISD5102SY directly replace the ISD5102SYR in existing designs?

A: Yes. The ISD5102SY is electrically and mechanically equivalent to the ISD5102SYR. Both parts share identical I2C interface specifications, 28-SOIC package dimensions, signal characteristics, sampling frequency, duration capacity, and operating parameters. No circuit modifications are required.

Q: What is the difference between the ISD5102SYR and ISD5102SY?

A: The primary differences are product status and packaging format. The ISD5102SYR is obsolete, while the ISD5102SY is in active production. The ISD5102SY is supplied in tube packaging and carries ROHS3 compliance certification. All functional and electrical specifications are identical.

Q: Are there any compatibility concerns with the 28-SOIC package?

A: No. Both parts use the identical 28-SOIC (0.295", 7.50mm Width) surface mount package. PCB footprints, reflow profiles, and assembly processes remain unchanged.

Q: Does the ISD5102SY support the same I2C interface as the ISD5102SYR?

A: Yes. Both parts implement identical I2C interface protocols and are fully compatible with existing firmware and control logic.

Q: What is the significance of ROHS3 compliance on the ISD5102SY?

A: ROHS3 compliance indicates the ISD5102SY meets current environmental and regulatory standards for restricted hazardous substances. This is relevant for applications subject to environmental regulations or customer requirements mandating RoHS compliance.

Q: Can the ISD5102SY be used in applications originally designed for the ISD5102SYR?

A: Yes. The ISD5102SY is a direct functional and electrical equivalent. Applications utilizing the ISD5102SYR can transition to the ISD5102SY without design changes or re-qualification, provided procurement and assembly processes accommodate the tube packaging format.
