AD7870JPZ Equivalent & Substitute Parts

Part Overview

The AD7870JPZ is a 12-bit Analog to Digital Converter (ADC) manufactured by Analog Devices Inc., designed for single-ended input data acquisition applications. This SAR (Successive Approximation Register) architecture device operates at a 100 kHz sampling rate and features both SPI and parallel data interfaces. The part is currently in active production status with 2000 units available in inventory. Alternative equivalent parts may be required due to supply constraints, procurement lead times, or specific application requirements within compatible parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Equivalent substitution for the AD7870JPZ is determined by strict alignment across the following critical parameters:

• 12-bit resolution requirement
• 100 kHz sampling rate specification
• Single-ended input configuration
• SAR architecture with internal reference
• ±5V dual supply voltage (both analog and digital)
• 28-PLCC surface mount package
• Operating temperature range of 0°C to 70°C
• SPI and parallel data interface support
• ROHS3 compliance and MSL 3 rating

Parts meeting all these specifications are classified as direct parametric equivalents and may be substituted without circuit redesign or application modification.

Parameter Comparison

Engineering Selection Recommendations

Both the AD7870JPZ and AD7870LPZ are active production parts from Analog Devices Inc. with identical electrical and mechanical specifications. Selection between these equivalents should be based on:

• Inventory availability and procurement lead times
• Supply chain logistics and regional distribution
• Cost considerations within the same product family
• Project timeline requirements

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and commercial applications. The MSL 3 rating (168 hours) applies uniformly across both variants, requiring standard moisture control during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can AD7870LPZ be used as a direct replacement for AD7870JPZ?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, resolution, sampling rate, supply voltages, package type, and operating temperature range. No circuit modifications are required.

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

A: No. Both parts use the 28-PLCC (J-Lead) package with identical pinout and mechanical dimensions (11.51 x 11.51 mm).

Q: What is the significance of the "J" and "L" designators in the part numbers?

A: These designators indicate different temperature or performance grades within the AD7870 product family. However, both variants specified here share identical operating temperature ranges (0°C to 70°C) and all critical electrical parameters.

Q: Are both parts RoHS compliant?

A: Yes. Both AD7870JPZ and AD7870LPZ are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the MSL rating and why does it matter?

A: Both parts carry an MSL 3 rating with a 168-hour floor life. This indicates moisture sensitivity level 3, requiring standard moisture control during storage. Components must be stored in dry conditions and handled according to IPC-A-610 standards.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that inventory and supply chain considerations are addressed. Both parts meet identical functional and compliance requirements for surface mount assembly processes.
