Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADS7253IRTER is determined by strict equivalence across the following critical parameters:

• 12-bit resolution and 1M samples per second sampling rate
• 2 independent SAR converter architecture with simultaneous sampling capability
• Pseudo-differential and single-ended input configuration
• SPI digital interface protocol
• 5V analog supply and 1.65V ~ 5.5V digital supply voltage compatibility
• 16-WQFN (3x3) surface mount package with exposed pad
• Operating temperature range of -40°C ~ 125°C
• Active product status with current manufacturing support

The ADS7253IRTET qualifies as a parametric equivalent based on identical electrical specifications and mechanical compatibility. The primary distinction between these parts is packaging format: the ADS7253IRTER is supplied in standard packaging, while the ADS7253IRTET is supplied in Tape & Reel (TR) format for automated assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Both the ADS7253IRTER and ADS7253IRTET maintain identical electrical and functional specifications, ensuring direct substitution capability at the circuit level. Selection between these parts should be based on supply chain requirements and manufacturing processes:

The ADS7253IRTER in standard packaging is suitable for low-volume applications, prototype development, and situations where manual component handling is acceptable. The ADS7253IRTET in Tape & Reel format is optimized for high-volume production environments utilizing automated pick-and-place assembly equipment, offering improved handling efficiency and reduced labor costs in manufacturing operations.

Both parts carry active product status from Texas Instruments with full RoHS3 compliance and REACH unaffected designation, ensuring regulatory compliance and long-term availability. Moisture Sensitivity Level (MSL) rating of 2 (1 Year) applies to both variants, requiring standard moisture control during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can ADS7253IRTET be used as a direct replacement for ADS7253IRTER in circuit design?

A: Yes. Both parts are electrically and functionally identical. The only difference is packaging format. Circuit performance, pin configuration, and electrical characteristics are equivalent.

Q: What is the difference between standard packaging and Tape & Reel format?

A: Standard packaging (ADS7253IRTER) supplies individual components suitable for manual assembly or low-volume production. Tape & Reel format (ADS7253IRTET) packages components on continuous tape for automated assembly equipment, improving throughput in high-volume manufacturing.

Q: Are there any compatibility issues when switching between these part numbers?

A: No compatibility issues exist. Both parts use identical 16-WQFN (3x3) surface mount packages with exposed pads. PCB footprints, solder reflow profiles, and assembly processes are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ADS7253IRTER and ADS7253IRTET carry ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity ratings (MSL 2, 1 Year).

Q: What supply voltage requirements apply to both parts?

A: Both parts require 5V analog supply voltage and 1.65V to 5.5V digital supply voltage. Operating temperature range is -40°C to 125°C for both variants.

Q: Is inventory availability a factor in part selection?

A: Inventory levels may vary between packaging formats. ADS7253IRTET typically maintains higher stock levels due to automated assembly demand. Verify current availability with your supplier for specific project timelines.
