ADS42JB69IRGC25 Equivalent & Substitute Parts

Part Overview

The ADS42JB69IRGC25 is a 16-bit pipelined analog-to-digital converter manufactured by Texas Instruments, designed for high-speed data acquisition applications. This device features dual differential inputs with simultaneous sampling capability and JESD204B data interface, operating at 250 MSPS. The part is currently classified as obsolete, making identification of active equivalent alternatives essential for ongoing production and design continuity.

Substitute Part Grouping Explanation

Substitution of the ADS42JB69IRGC25 is determined by strict equivalence across all electrical and mechanical parameters. The substitute parts identified maintain identical specifications for resolution (16-bit), sampling rate (250 MSPS), input configuration (2 differential inputs), data interface (JESD204B), package type (64-VQFN 9x9), supply voltage ranges (1.7V ~ 1.9V analog and digital), and operating temperature range (-40°C ~ 85°C).

The primary distinction between substitute parts lies in packaging format and product status. The ADS42JB69IRGCR maintains Tape & Reel packaging identical to the main part but carries Active product status. The ADS42JB69IRGCT offers the same electrical specifications with Cut Tape & Digi-Reel® packaging format and Active product status. Both substitutes are fully compliant with ROHS3, REACH, and identical MSL ratings.

Engineering Selection Recommendations

Both ADS42JB69IRGCR and ADS42JB69IRGCT are direct electrical and mechanical equivalents to the obsolete ADS42JB69IRGC25. Selection between these two active alternatives depends on procurement and assembly requirements.

The ADS42JB69IRGCR maintains identical Tape & Reel packaging to the original part, providing continuity for automated assembly processes already configured for TR format. This part carries Active product status with 878 units in stock.

The ADS42JB69IRGCT offers the same electrical specifications with Cut Tape & Digi-Reel® packaging, suitable for applications requiring flexible quantity handling or lower-volume production runs. This variant carries Active product status with 1644 units in stock, providing greater availability.

Both parts maintain full compliance with ROHS3 and REACH requirements, identical MSL ratings, and equivalent supply voltage and temperature specifications. Selection should be based on packaging format compatibility with existing assembly infrastructure and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can ADS42JB69IRGCR and ADS42JB69IRGCT be used interchangeably with ADS42JB69IRGC25?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, resolution, sampling rate, input configuration, data interface, supply voltages, and operating temperature range. The only differences are packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) and product status (Active versus Obsolete).

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging provides components on continuous carrier tape suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® packaging offers the same components in cut tape format with optional reel packaging, providing flexibility for lower-volume or mixed-quantity orders.

Q: Are there any compliance differences between the substitute parts?

A: No. All three parts maintain identical ROHS3 compliance, REACH Unaffected status, MSL rating of 3 (168 Hours), and equivalent ECCN and HTSUS classifications.

Q: Which substitute part should be selected for new designs?

A: Either ADS42JB69IRGCR or ADS42JB69IRGCT is suitable for new designs. Selection depends on packaging format requirements and supply chain preferences. Both carry Active product status and are supported by Texas Instruments.

Q: Is the 64-VQFN package identical across all three parts?

A: Yes. All three parts use the 64-VQFN (9x9) package with exposed pad, ensuring identical PCB footprint and assembly requirements.
