ADS8513IDWG4 Equivalent & Substitute Parts

Part Overview

The ADS8513IDWG4 is a 16-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for single-ended input data acquisition applications. It features a Successive Approximation Register (SAR) architecture with a 40 kSPS sampling rate and operates on 5V supply voltage for both analog and digital domains. The device is packaged in a 16-SOIC surface mount package.

The ADS8513IDWG4 is currently discontinued at DiGi Electronics, making it necessary to identify equivalent or substitute components for ongoing production, maintenance, or new design implementations. Equivalent parts must maintain identical electrical performance and mechanical compatibility to ensure seamless integration into existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADS8513IDWG4 is determined by strict equivalence across the following critical parameters:

• Resolution: 16-bit ADC
• Sampling Rate: 40 kSPS
• Input Configuration: Single-ended, 1 input channel
• Communication Protocol: SPI interface
• Architecture: SAR-based conversion
• Reference Options: External and internal reference support
• Supply Voltage: 5V analog and digital
• Operating Temperature Range: -40°C to 85°C
• Package: 16-SOIC surface mount form factor
• Compliance: ROHS3 certification

All identified substitute parts maintain these electrical and mechanical specifications, ensuring functional and physical compatibility with the original ADS8513IDWG4 design.

Engineering Selection Recommendations

ADS8513IDW (MFR Recommended): This part is the primary substitute for the ADS8513IDWG4. It maintains identical electrical specifications and package configuration while offering the advantage of Active product status, ensuring continued availability and manufacturer support. The ADS8513IDW is ROHS3 compliant with a Moisture Sensitivity Level (MSL) of 2 (1 Year), matching the original part's compliance profile.

ADS7813U (Parametric Equivalent): This part provides full electrical and mechanical equivalence to the ADS8513IDWG4 across all critical parameters. However, it carries a Last Time Buy status, indicating limited future availability. The ADS7813U has an MSL rating of 3 (168 Hours), which differs from the original part's MSL 2 rating. This part is suitable for immediate replacement but should not be considered for long-term production planning.

For new designs or ongoing production requirements, the ADS8513IDW is the recommended choice due to its Active status and assured supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the ADS7813U be used as a direct replacement for the ADS8513IDWG4?

A: Yes. The ADS7813U is electrically and mechanically equivalent to the ADS8513IDWG4. Both devices share identical resolution (16-bit), sampling rate (40 kSPS), input configuration (single-ended), SPI interface, and 16-SOIC package. However, the ADS7813U is in Last Time Buy status, limiting its availability for future orders.

Q: What is the difference between the ADS8513IDWG4 and ADS8513IDW?

A: The ADS8513IDW is the Active production variant of the ADS8513 base product number. Both parts are electrically identical and use the same 16-SOIC package. The primary difference is product status: the ADS8513IDWG4 is discontinued, while the ADS8513IDW remains in active production with full manufacturer support.

Q: Are there any packaging differences between these substitute parts?

A: All three parts (ADS8513IDWG4, ADS7813U, and ADS8513IDW) use the 16-SOIC surface mount package with identical dimensions (0.295" width, 7.50mm). They are mechanically interchangeable on PCBs designed for the original part.

Q: What does MSL rating mean, and does the difference between MSL 2 and MSL 3 affect substitution?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to ambient conditions before soldering. MSL 2 allows 1 year of storage, while MSL 3 allows 168 hours. The ADS7813U's higher MSL rating requires stricter moisture control during handling and storage but does not affect electrical performance or functional compatibility.

Q: Which substitute part should I choose for a new design?

A: The ADS8513IDW is the recommended choice for new designs. It maintains full electrical and mechanical compatibility with the ADS8513IDWG4 while offering Active product status, ensuring long-term availability and manufacturer support.
