AD5302ARM-REEL7 Equivalent & Substitute Parts

Part Overview

The AD5302ARM-REEL7 is an 8-bit digital-to-analog converter (DAC) with dual output channels, designed for data acquisition applications requiring voltage-buffered outputs. This component features a string DAC architecture with SPI/DSP interface compatibility and operates across a 2.5V to 5.5V supply range. The AD5302ARM-REEL7 is classified as obsolete, making equivalent substitute parts necessary for ongoing production and design continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the AD5302ARM-REEL7 is determined by strict equivalence across the following critical parameters:

Resolution & Channel Count: 8-bit resolution with 2 D/A converters
Electrical Performance: 8µs settling time, ±0.15/±0.02 LSB INL/DNL specifications
Interface & Architecture: SPI/DSP data interface with string DAC architecture
Supply Voltage Ranges: 2.5V to 5.5V for both analog and digital supplies
Output Characteristics: Voltage-buffered output with external reference
Package Specification: 10-MSOP surface mount package
Operating Temperature Range: -40°C to 105°C

All substitute parts listed maintain identical electrical and mechanical specifications across these parameters. Packaging format (tube, cut tape, or reel configuration) and product status (active vs. obsolete) are secondary considerations that do not affect functional interchangeability.

Engineering Selection Recommendations

For applications currently using the AD5302ARM-REEL7, the following selection criteria apply:

Active Product Status Priority: AD5302ARMZ and AD5302ARMZ-REEL7 are classified as active products and represent the primary substitution path. These variants maintain full electrical and mechanical equivalence while ensuring long-term availability and manufacturer support.

Compliance Considerations: AD5302ARMZ, AD5302ARMZ-REEL7, and AD5302BRMZ-REEL7 carry ROHS3 compliance and REACH unaffected status, making them suitable for applications with regulatory requirements. The original AD5302ARM-REEL7 and AD5302BRM-REEL7 do not specify these compliance certifications.

Packaging Format: Selection between tube (AD5302ARMZ), cut tape with reel (AD5302ARMZ-REEL7, AD5302BRMZ-REEL7), or standard reel packaging should align with procurement and assembly workflow requirements. All packaging formats are functionally equivalent.

Inventory Availability: AD5302BRMZ-REEL7 offers the highest current inventory (9,379 units), followed by AD5302ARMZ-REEL7 (3,468 units) and AD5302ARMZ (2,199 units).

Frequently Asked Questions (FAQ)

Q: Can AD5302ARMZ be used as a direct replacement for AD5302ARM-REEL7?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The primary difference is packaging format (tube vs. reel) and product status (active vs. obsolete). Functional interchangeability is complete.

Q: What is the difference between AD5302ARMZ and AD5302BRMZ-REEL7?

A: Both parts are parametrically equivalent with identical electrical specifications. The difference lies in the part number designation (ARM vs. BRM suffix) and product status. AD5302BRMZ-REEL7 is active with higher inventory availability.

Q: Are there any compliance differences between substitute parts?

A: AD5302ARMZ, AD5302ARMZ-REEL7, and AD5302BRMZ-REEL7 carry ROHS3 compliance and REACH unaffected certifications. The original AD5302ARM-REEL7 and AD5302BRM-REEL7 do not specify these certifications. For applications requiring regulatory compliance, select from the certified variants.

Q: Does packaging format affect electrical performance?

A: No. Tube, cut tape, and reel packaging formats are logistics and assembly considerations only. All variants deliver identical electrical performance and operating characteristics.

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

A: AD5302ARMZ-REEL7 or AD5302BRMZ-REEL7 are recommended for new designs. Both are active products with ROHS3 compliance, REACH unaffected status, and established long-term availability.
