Engineering Selection Recommendations

Primary Substitutes (Parametric Equivalents):

ADS58C28IRGCR and ADS58C28IRGCT are direct parametric equivalents to the ADS58C28IRGC25. Both parts maintain identical electrical specifications including 11-bit resolution, 200 megasamples per second sampling rate, dual differential inputs, and internal reference configuration. Both are active products with ROHS3 compliance, providing improved product lifecycle status and regulatory alignment compared to the obsolete main part. The ADS58C28IRGCT is packaged in Tape & Reel format, while ADS58C28IRGCR packaging format is not specified. Selection between these two should be based on packaging requirements and inventory availability.

Alternative Substitute (Manufacturer Recommended):

ADS62C17IRGCT is the manufacturer-recommended substitute. This part maintains functional equivalence across all core parameters: 11-bit resolution, 200 megasamples per second, dual differential inputs, pipelined architecture, and identical package configuration. The primary difference is the analog supply voltage range of 3.15V to 3.8V with support for both external and internal reference types, compared to the 1.75V to 1.9V internal reference specification of the main part. This part is active with ROHS3 compliance and EAR99 export classification. Selection of ADS62C17IRGCT requires verification that system power supply architecture can accommodate the higher analog voltage requirement.

Compliance Considerations:

All substitute parts carry ROHS3 compliance and REACH Unaffected status, providing regulatory advantages over the non-compliant main part. The moisture sensitivity level remains consistent at MSL 3 (168 hours) across all parts.

Frequently Asked Questions (FAQ)

Q: Can ADS58C28IRGCR be used as a direct replacement for ADS58C28IRGC25?

A: Yes. ADS58C28IRGCR is a parametric equivalent with identical electrical specifications, including resolution, sampling rate, input configuration, and supply voltage requirements. The primary difference is product status (active versus obsolete) and RoHS compliance improvement. Packaging format differences should be verified based on assembly requirements.

Q: What is the key difference between ADS58C28IRGCT and ADS62C17IRGCT?

A: Both parts are functionally equivalent in terms of resolution, sampling rate, and package configuration. The primary difference is the analog supply voltage: ADS58C28IRGCT operates at 1.75V to 1.9V with internal reference only, while ADS62C17IRGCT operates at 3.15V to 3.8V and supports both external and internal reference types. System power supply architecture must be evaluated before selecting ADS62C17IRGCT.

Q: Are all substitute parts available in Tape & Reel packaging?

A: ADS58C28IRGCT and ADS62C17IRGCT are specified as Tape & Reel (TR) packaged. ADS58C28IRGCR packaging format is not specified in available documentation. Packaging format confirmation is required before procurement.

Q: Do all substitute parts maintain the same operating temperature range?

A: Yes. All substitute parts operate across the identical temperature range of -40°C to 85°C, matching the main part specification.

Q: What is the impact of switching to ADS62C17IRGCT regarding reference voltage configuration?

A: ADS62C17IRGCT supports both external and internal reference types, compared to internal reference only for the main part and other substitutes. If the system design utilizes internal reference exclusively, this capability difference has no impact. If external reference capability is desired, ADS62C17IRGCT provides this option. The analog supply voltage requirement of 3.15V to 3.8V must be accommodated by system power architecture.

Q: Are moisture sensitivity and REACH compliance identical across all parts?

A: Yes. All parts maintain MSL 3 (168 hours) moisture sensitivity level and REACH Unaffected status. These specifications are consistent across the main part and all substitutes.
