ISD1620BPIY Equivalent & Substitute Parts

Part Overview

The ISD1620BPIY is a voice record/playback integrated circuit manufactured by Nuvoton Technology Corporation, part of the ChipCorder® series. This component functions as a single-message voice recording and playback device with a duration range of 13.3 to 40 seconds, featuring pushbutton interface control and automatic gain control. The ISD1620BPIY is classified as obsolete, necessitating identification of active equivalent components to maintain system functionality and ensure continued component availability for new designs or legacy system maintenance.

Substitute Part Grouping Explanation

Substitution of the ISD1620BPIY is determined by functional and electrical equivalence within the ChipCorder® series. The primary substitute, ISD1620BSY, maintains identical core functionality across the following critical parameters:

• Identical voice record/playback capability with single-message operation
• Matching sampling frequency range (4 ~ 12 kHz)
• Identical duration specification (13.3 ~ 40 Sec)
• Matching pushbutton interface type
• Identical input signal type (Microphone)
• Identical output signal configuration (Analog - Single Ended, PWM Speaker Output)
• Matching supply voltage range (2.4 V ~ 5.5 V)
• Identical oscillator type (Internal)
• Identical automatic gain control feature
• Same manufacturer (Nuvoton Technology Corporation)
• Same series designation (ChipCorder®)

The ISD1620BSY differs in packaging format (16-SOIC surface mount versus 16-DIP through hole) and operating temperature range, which are secondary considerations for functional substitution.

Parameter Comparison

Engineering Selection Recommendations

The ISD1620BSY serves as the functional equivalent to the obsolete ISD1620BPIY for voice record/playback applications requiring ChipCorder® series functionality. Selection between these components is determined by board-level design constraints rather than functional capability.

For through-hole mounting applications with existing PCB layouts designed for 16-DIP packages, the ISD1620BPIY remains the appropriate choice if inventory is available. However, given the obsolete status of the ISD1620BPIY, new designs should incorporate the ISD1620BSY, which is active and maintains full functional equivalence.

The ISD1620BSY operates within a narrower temperature range (0°C ~ 70°C versus -40°C ~ 85°C), which must be evaluated against application requirements. Applications requiring extended low-temperature operation below 0°C or high-temperature operation above 70°C should confirm compatibility with the ISD1620BSY's specified operating range.

Both components maintain identical REACH and ECCN compliance classifications, ensuring regulatory equivalence for international applications.

Frequently Asked Questions (FAQ)

Q: Can the ISD1620BSY directly replace the ISD1620BPIY in existing designs?

A: Functional replacement is possible; however, package differences require PCB redesign. The ISD1620BPIY uses 16-DIP through-hole mounting, while the ISD1620BSY uses 16-SOIC surface-mount packaging. Electrical functionality is identical across all voice record/playback parameters.

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

A: The primary differences are mounting type (through-hole versus surface-mount), package footprint dimensions, and operating temperature range. The ISD1620BSY operates from 0°C to 70°C, while the ISD1620BPIY operates from -40°C to 85°C. All voice processing specifications remain identical.

Q: Is the ISD1620BSY suitable for applications requiring the full -40°C to 85°C temperature range?

A: No. The ISD1620BSY is specified for 0°C to 70°C operation. Applications requiring extended temperature operation must confirm that the narrower range meets system requirements or identify alternative components.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both components share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS codes (8542.39.0001), ensuring equivalent regulatory treatment.

Q: Why is the ISD1620BPIY listed as obsolete?

A: The ISD1620BPIY is obsolete due to industry transition toward surface-mount technology. The ISD1620BSY represents the active equivalent within the ChipCorder® series and is the recommended component for new designs.

Q: Can I use the ISD1620BSY in a legacy system designed for the ISD1620BPIY?

A: Functional replacement is possible if the PCB can be redesigned to accommodate the 16-SOIC surface-mount package and the operating temperature range meets application requirements. Direct socket substitution is not possible due to package differences.
