ADS1286PC Equivalent & Substitute Parts Reference

Part Overview

The Texas Instruments ADS1286PC is a Data Acquisition category device, specifically a 12-bit Successive Approximation Register (SAR) Analog to Digital Converter (ADC) with a single differential input. It features an 8-DIP (0.300", 7.62mm) through-hole package and communicates via an SPI interface. The device supports an external reference, operates at a 5V analog and digital supply, and is rated for industrial temperature range (-40°C to 85°C). The ADS1286PC is classified as obsolete, necessitating the selection of alternative models to maintain long-term design support or resolve supply chain issues.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined using parameters ensured to match the primary electrical and mechanical requirements for the Data Acquisition ADC product category. The following parameters are used for screening: number of bits, number of inputs, input type, data interface, configuration, ratio S/H:ADC, architecture, reference type, voltage supply, operating temperature, package/case, mounting type, RoHS status, MSL, and REACH status. Substitute models listed here share these core attributes, ensuring fitting electrical characteristics, footprint, and compliance status.

Parameter Comparison

Engineering Selection Recommendations

The ADS1286PC is listed as obsolete, while each substitute part (LTC1286IN8#PBF, MCP3201-BI/P, MCP3201-CI/P) is classified as active. All parts conform to ROHS3 compliance and have an MSL rating of 1 (unlimited), indicating suitability for a wide range of assembly processes. The temperature range and REACH status are matched across all parts, ensuring environmental and regulatory compatibility. The physical package (8-DIP) and through-hole mounting are identical, providing drop-in mechanical compatibility. These factors confirm suitability for direct substitution based on compliance, mechanical form factor, and regulatory status.

Frequently Asked Questions (FAQ)

Q: What technical criteria are used for finding a substitute for ADS1286PC?
A: Substitutes are chosen based on number of bits, data interface, input configuration, operating voltage, package, mounting style, temperature range, and compliance certifications.

Q: Are all substitute ADC parts pin-compatible with the ADS1286PC?
A: Substitute models use the same 8-DIP (0.300", 7.62mm) through-hole package. Detailed pinout verification should be confirmed using the manufacturer datasheets to ensure complete pin compatibility.

Q: What package styles do the substitutes use?
A: ADS1286PC and all listed substitutes use 8-DIP (0.300", 7.62mm) through-hole packages, designated 8-PDIP by suppliers.

Q: Are the substitutes environmentally compliant?
A: All listed substitutes are ROHS3 Compliant, MSL 1 (Unlimited), and REACH Unaffected.

Q: Are there differences in the input type among the substitutes?
A: The ADS1286PC and LTC1286IN8#PBF feature differential input types, while MCP3201 variants use pseudo-differential input configuration.

Q: Is there a difference in sample rates among the compared devices?
A: ADS1286PC has a 20k sampling rate, LTC1286IN8#PBF offers 12.5k, and MCP3201 variants support up to 100k per second, as provided in the input.
