ADS7828EB/250G4 Equivalent & Substitute Parts

Part Overview

The ADS7828EB/250G4 is a 12-bit Analog to Digital Converter (ADC) with 8 inputs, SAR architecture, and I2C interface, manufactured by Texas Instruments in a 16-TSSOP surface mount package. This part is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications. The ADS7828 base product family provides direct functional equivalents with identical electrical and mechanical specifications across multiple packaging and qualification variants.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADS7828EB/250G4 is determined by strict equivalence across the following critical parameters: 12-bit resolution, 8-input configuration, 50k sampling rate, I2C data interface, SAR architecture, dual supply voltage support (2.7V–3.6V and 5V), external and internal reference capability, and 16-TSSOP package geometry. All substitute parts maintain identical electrical performance and pinout compatibility. Differences exist only in product status (active vs. discontinued), packaging format (tape/reel vs. bulk), and qualification level (commercial vs. automotive). These differences do not affect functional interchangeability in equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—ADS7828E/250, ADS7828E/2K5, and ADS7828EIPWRQ1—are functionally equivalent to the discontinued ADS7828EB/250G4 and provide direct replacement capability. Selection between them depends on application requirements and supply chain considerations:

ADS7828E/250 and ADS7828E/2K5 are commercial-grade variants with identical electrical specifications and MSL 1 rating. Both are currently in active production status. The primary distinction between these two is packaging format and inventory availability; ADS7828E/2K5 maintains higher stock levels (11,400 units) compared to ADS7828E/250 (1,422 units).

ADS7828EIPWRQ1 is an automotive-qualified variant meeting AEC-Q100 standards with MSL 2 rating. This part is suitable for applications requiring automotive-grade reliability and traceability. It maintains the same electrical performance and pinout as commercial variants but includes automotive qualification documentation and stricter manufacturing controls.

For non-automotive applications with standard commercial requirements, ADS7828E/250 or ADS7828E/2K5 provide cost-effective substitution. For automotive or mission-critical applications requiring qualification documentation, ADS7828EIPWRQ1 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts pin-compatible with the ADS7828EB/250G4?

A: Yes. All substitute parts use the 16-TSSOP package with identical pinout and electrical interface. Direct board-level replacement is possible without circuit modification.

Q: What is the difference between ADS7828E/250 and ADS7828E/2K5?

A: Both parts are electrically and functionally identical. The designation suffix indicates packaging quantity: /250 represents 250-unit tape/reel packaging, while /2K5 represents 2,500-unit tape/reel packaging. Selection depends on procurement volume requirements and inventory availability.

Q: Can ADS7828EIPWRQ1 be used in non-automotive applications?

A: Yes. ADS7828EIPWRQ1 is a superset of commercial-grade performance with additional automotive qualification. It functions identically to commercial variants in any application. However, the automotive qualification adds cost; commercial variants are more economical for non-automotive use.

Q: What does MSL 2 (1 Year) on ADS7828EIPWRQ1 mean compared to MSL 1 (Unlimited) on other variants?

A: MSL (Moisture Sensitivity Level) indicates the maximum time a component can be stored in standard conditions before requiring baking before reflow soldering. MSL 1 (Unlimited) allows indefinite storage without baking. MSL 2 (1 Year) requires baking if the component has been stored for more than one year in standard humidity conditions. This difference does not affect electrical performance or long-term reliability after soldering.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting environmental and regulatory requirements for commercial and industrial applications.

Q: What inventory considerations should guide part selection?

A: ADS7828E/2K5 maintains the highest current inventory (11,400 units), followed by ADS7828EIPWRQ1 (15,100 units) and ADS7828E/250 (1,422 units). For immediate procurement needs, ADS7828EIPWRQ1 or ADS7828E/2K5 provide superior availability. The original ADS7828EB/250G4 is discontinued and no longer available.
