ADS1253E Equivalent & Substitute Parts

Part Overview

The ADS1253E is a 24-bit analog-to-digital converter manufactured by Texas Instruments, designed for multi-channel data acquisition applications. This device features a sigma-delta architecture with four differential inputs, SPI data interface, and operates from a single 5V supply. The ADS1253E is currently in active production status with 2520 units available in inventory.

Identifying equivalent and substitute parts is necessary when the primary part becomes unavailable, when supply chain constraints occur, or when design flexibility is required for procurement optimization. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ADS1253E are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Resolution: 24-bit
• Sampling rate: 20k samples per second
• Input configuration: 4 differential inputs
• Data interface: SPI protocol
• Architecture: Sigma-delta modulation
• Supply voltages: 5V analog and digital
• Operating temperature range: -40°C to 85°C
• Package: 16-SSOP surface mount
• Compliance: ROHS3 and REACH standards

Parts meeting all these criteria are classified as parametric equivalents and may be used as direct substitutes in applications where the ADS1253E is specified.

Parameter Comparison

Engineering Selection Recommendations

The ADS1253E is the primary selection for new designs and ongoing production due to its active product status and current availability of 2520 units in inventory.

The ADS1253EG4 is a parametric equivalent that maintains all electrical and mechanical specifications identical to the ADS1253E. However, this part is discontinued at DiGi Electronics with 681 units available in inventory. The ADS1253EG4 may be used as a substitute only when the ADS1253E becomes unavailable, as both parts are ROHS3 compliant and carry identical MSL ratings.

For long-term supply chain planning, the ADS1253E should be the preferred selection due to its active production status. The ADS1253EG4 should be reserved for applications where immediate substitution is required and the ADS1253E cannot be sourced within project timelines.

Frequently Asked Questions (FAQ)

Q: Can the ADS1253EG4 be used as a direct replacement for the ADS1253E?

A: Yes. The ADS1253EG4 is a parametric equivalent with identical electrical specifications, pin configuration, and package type. No circuit modifications are required for substitution.

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

A: Both parts are ROHS3 compliant and REACH unaffected. Both carry MSL rating 2 (1 Year). No compliance differences exist.

Q: What is the difference between ADS1253E and ADS1253EG4?

A: The primary difference is product status. The ADS1253E is in active production, while the ADS1253EG4 is discontinued at DiGi Electronics. All electrical and mechanical parameters are identical.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts use the 16-SSOP surface mount package with identical pin assignments and mechanical dimensions (0.154" width, 3.90mm). No PCB layout modifications are necessary.

Q: What should I consider when selecting between these parts?

A: Selection should be based on availability and supply chain status. The ADS1253E is recommended for new designs and ongoing production. The ADS1253EG4 should be used only when the ADS1253E is unavailable and immediate substitution is required.
