Substitute Part Grouping Explanation

Substitute parts for the ADS5482IRGC25 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: 16 bits
Sampling Rate: 105 MSPS
Input Configuration: 1 differential input
Data Interface: LVDS - Parallel output
Architecture: Pipelined ADC with 1:1 S/H:ADC ratio
Reference Options: External and Internal
Supply Voltages: Analog (3.1V ~ 3.6V, 5V) and Digital (3V ~ 3.6V)
Operating Temperature: -40°C ~ 85°C
Package: 64-VQFN (9x9) with exposed pad
Mounting: Surface mount

The ADS5482IRGC25 differs from its substitutes only in packaging format (individual tube) and product status (obsolete). The substitute parts ADS5482IRGCR and ADS5482IRGCT maintain identical electrical performance and physical package specifications while offering active product status and alternative packaging options.

Engineering Selection Recommendations

The ADS5482IRGC25 is obsolete and should be replaced with either ADS5482IRGCR or ADS5482IRGCT for new designs and production applications. Both substitute parts are active products with identical electrical specifications and package dimensions.

ADS5482IRGCR is recommended for high-volume production environments requiring tape and reel packaging. This format is optimized for automated assembly processes and provides 968 units per reel configuration.

ADS5482IRGCT is recommended for applications requiring cut tape or Digi-Reel® packaging options, offering flexibility for lower-volume production runs or mixed-component sourcing. This variant provides 2000 units in stock.

Both substitutes comply with ROHS3 standards, addressing environmental and regulatory requirements that the obsolete ADS5482IRGC25 does not meet. Selection between ADS5482IRGCR and ADS5482IRGCT should be based on procurement volume requirements and assembly line packaging compatibility.

Frequently Asked Questions (FAQ)

Q: Can ADS5482IRGCR and ADS5482IRGCT be used interchangeably with ADS5482IRGC25?

A: Yes. All three parts are electrically and mechanically identical. They differ only in packaging format (tube versus tape & reel) and product status. The substitutes are direct replacements for PCB assembly and circuit operation.

Q: What is the difference between ADS5482IRGCR and ADS5482IRGCT?

A: Both parts have identical electrical specifications and physical packages. The difference is packaging format: ADS5482IRGCR uses standard tape and reel (TR) packaging, while ADS5482IRGCT uses cut tape (CT) and Digi-Reel® packaging. Selection depends on assembly equipment compatibility and procurement volume.

Q: Why is the ADS5482IRGC25 marked as obsolete?

A: The ADS5482IRGC25 is no longer in active production. Texas Instruments continues to manufacture the same device under the active part numbers ADS5482IRGCR and ADS5482IRGCT. Existing inventory of the obsolete variant may be available through authorized distributors.

Q: Are there any compliance differences between the obsolete and active variants?

A: Yes. The ADS5482IRGC25 is RoHS non-compliant, while both ADS5482IRGCR and ADS5482IRGCT are ROHS3 compliant. For applications subject to environmental regulations or customer requirements, the active variants are required.

Q: Will the substitute parts work with existing PCB designs for ADS5482IRGC25?

A: Yes. The 64-VQFN (9x9) package dimensions, pin configuration, and electrical specifications are identical. No PCB redesign is required for substitution.

Q: What is the moisture sensitivity level for these parts?

A: All three variants have an MSL rating of 3 (168 Hours), indicating identical moisture handling and storage requirements.
