ADS8327IPWR Equivalent & Substitute Parts

Part Overview

The ADS8327IPWR is a 16-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for single-channel data acquisition applications. This SAR (Successive Approximation Register) architecture device operates with a 500 kSPS sampling rate and supports both differential and single-ended input configurations via SPI interface. The part is currently in active production status with ROHS3 compliance and is available in 16-TSSOP surface mount packaging. Identifying equivalent substitute parts ensures design flexibility, supply chain continuity, and procurement optimization when the primary part number becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

The ADS8327IBPWR qualifies as a parametric equivalent to the ADS8327IPWR based on strict alignment across all critical electrical and mechanical specifications. Both parts share identical core parameters: 16-bit resolution, 500 kSPS sampling rate, single-channel input configuration, differential and single-ended input support, SPI data interface, SAR architecture, external reference requirement, 5V analog supply, 1.65V to 5.5V digital supply range, -40°C to 85°C operating temperature, and 16-TSSOP packaging. The substitution is valid because all allowed electrical parameters, mechanical dimensions, and compliance certifications remain constant between the two part numbers. The difference in part number suffix reflects manufacturing process or date code variations within the same product family, not functional or electrical divergence.

Parameter Comparison

Engineering Selection Recommendations

Both the ADS8327IPWR and ADS8327IBPWR are active production parts with identical compliance certifications and regulatory status. Selection between these parts should be based on availability and procurement lead time rather than technical performance differences. Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification. The MSL rating of 2 (1 Year) applies uniformly to both parts, requiring equivalent moisture control during storage and handling. For applications requiring the ADS8327IPWR, the ADS8327IBPWR provides direct functional substitution without circuit redesign or board layout modification.

Frequently Asked Questions (FAQ)

Q: Can the ADS8327IBPWR be used as a direct replacement for the ADS8327IPWR in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. No circuit modifications, firmware changes, or PCB layout adjustments are required for substitution.

Q: Are there any differences in pin configuration or package dimensions between these parts?

A: No. Both parts use the 16-TSSOP package with identical pin assignments and physical dimensions of 0.173" width and 4.40mm overall width. PCB footprints are interchangeable.

Q: Do both parts require the same external reference voltage configuration?

A: Yes. Both parts require an external reference voltage. The analog supply voltage is 5V for both, and digital supply voltage ranges from 1.65V to 5.5V identically.

Q: What is the significance of the different part number suffixes (IPWR vs. IBPWR)?

A: The suffix variation indicates different manufacturing process nodes or date codes within the same product family. Both suffixes represent the same functional device with identical electrical specifications and performance characteristics.

Q: Are moisture sensitivity levels the same for both parts?

A: Yes. Both parts carry an MSL rating of 2 (1 Year), requiring identical moisture control protocols during storage, handling, and assembly.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since all electrical, mechanical, and compliance parameters are identical, both parts can be used interchangeably within the same manufacturing lot without affecting product performance or reliability.
