ISD5116S Equivalent & Substitute Parts

Part Overview

The ISD5116S is a voice record/playback interface IC from Nuvoton Technology Corporation's ChipCorder® series, designed for multiple message applications with recording and playback durations of 8 minutes 44 seconds to 17 minutes 28 seconds. The device features I2C interface control, analog microphone input, and multiple output options including analog differential and PWM speaker outputs. The ISD5116S is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution for the ISD5116S is determined by strict equivalence across the following parameters:

• Interface protocol: I2C
• Input/output signal types: Analog - Single Ended, Microphone input; Analog - Single Ended, Analog Differential, PWM Speaker Output
• Sampling frequency range: 4 ~ 8 kHz
• Recording/playback duration: 8 Min 44 Sec ~ 17 Min 28 Sec
• Filter pass band: 1.7 ~ 3.4 kHz
• Multiple messaging capability
• Internal/External oscillator support
• Feature set: Auto Mute, Automatic Gain Control, Digital Data Storage, Volume Control
• Operating temperature range: 0°C ~ 70°C (TA)
• Supply voltage range: 2.7 V ~ 3.3 V
• Package compatibility: 28-pin configuration

The ISD5116S has two direct substitutes within the ChipCorder® series that maintain functional equivalence while differing in packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The ISD5116S is obsolete and no longer in active production. Both ISD5116PY and ISD5116SY are active alternatives from Nuvoton Technology Corporation with identical functional specifications.

ISD5116PY is suitable for through-hole mounting applications requiring 28-DIP package format. This variant maintains unlimited moisture sensitivity level (MSL 1) and is ROHS3 compliant.

ISD5116SY is suitable for surface-mount applications requiring 28-SOIC package format, matching the original ISD5116S mounting type. This variant is ROHS3 compliant with MSL 3 (168 hours), indicating moisture sensitivity requiring controlled storage conditions.

For new designs, either substitute part provides functional equivalence to the obsolete ISD5116S. Package selection depends on PCB assembly requirements: ISD5116PY for through-hole designs, ISD5116SY for surface-mount designs. Both substitutes offer improved compliance status (ROHS3) compared to the original part.

Frequently Asked Questions (FAQ)

Q: Can ISD5116PY and ISD5116SY be used interchangeably with ISD5116S?

A: Both parts are functionally equivalent to ISD5116S across all electrical and operational parameters. Interchangeability is limited by package format: ISD5116PY uses 28-DIP (through-hole), while ISD5116SY uses 28-SOIC (surface-mount), matching the original ISD5116S package type.

Q: What is the difference between ISD5116PY and ISD5116SY?

A: The primary differences are mounting type and package format. ISD5116PY is through-hole (28-DIP), while ISD5116SY is surface-mount (28-SOIC). Both maintain identical I2C interface, signal specifications, sampling frequency, duration, and feature sets. ISD5116SY has MSL 3 (168 hours) versus ISD5116PY's MSL 1 (unlimited).

Q: Why is the ISD5116S obsolete?

A: The ISD5116S is classified as obsolete by Nuvoton Technology Corporation. Active alternatives (ISD5116PY and ISD5116SY) are available with improved compliance status and equivalent functionality.

Q: Are there compliance differences between the substitutes?

A: Yes. The ISD5116S is RoHS non-compliant. Both ISD5116PY and ISD5116SY are ROHS3 compliant, meeting current environmental and regulatory requirements. All three parts are REACH unaffected and classified as EAR99.

Q: What does MSL 3 (168 hours) mean for ISD5116SY?

A: MSL 3 indicates the component requires controlled moisture exposure. The part can be exposed to ambient conditions for a maximum of 168 hours before soldering. Proper storage in dry conditions or desiccant packaging is required to maintain component integrity.

Q: Can I use ISD5116PY in a surface-mount PCB design?

A: No. ISD5116PY is a through-hole component (28-DIP package) and cannot be directly mounted on surface-mount PCB layouts. Use ISD5116SY for surface-mount applications.

Q: Can I use ISD5116SY in a through-hole PCB design?

A: No. ISD5116SY is a surface-mount component (28-SOIC package) and cannot be directly mounted in through-hole PCB layouts. Use ISD5116PY for through-hole applications.
