AD7280ABSTZ-RL Equivalent & Substitute Parts

Part Overview

The AD7280ABSTZ-RL is an active Battery Monitor IC designed for Lithium Ion battery packs with 1 to 6 cells. This Surface Mount device in 48-LQFP packaging provides real-time cell voltage monitoring, fault protection against over/under voltage conditions, and SPI interface communication. The part is currently in active production status with ROHS3 compliance and automotive-grade reliability standards. Identifying equivalent substitute parts ensures design flexibility, supply chain continuity, and access to alternative packaging or inventory options when the primary part number becomes unavailable or when specific application requirements necessitate alternative configurations.

Substitute Part Grouping Explanation

Substitution of the AD7280ABSTZ-RL is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Base product number (AD7280 series)
• Battery chemistry (Lithium Ion)
• Cell count range (1 ~ 6 cells)
• Fault protection capability (Over/Under Voltage)
• Communication interface (SPI)
• Operating temperature range (-40°C ~ 105°C)
• Package type (48-LQFP, 7x7mm)
• Mounting technology (Surface Mount)
• RoHS compliance status (ROHS3)
• MSL rating (3, 168 Hours)

The identified substitute part AD7280AWBSTZ-RL maintains full parametric equivalence across all functional and environmental specifications. The primary difference lies in packaging configuration (Cut Tape & Digi-Reel versus Tape & Reel) and automotive-grade qualification of the substitute variant.

Parameter Comparison

Engineering Selection Recommendations

Both the AD7280ABSTZ-RL and AD7280AWBSTZ-RL are active production parts with identical functional specifications and environmental ratings. Selection between these parts should be based on the following factors:

AD7280ABSTZ-RL is appropriate for applications requiring standard-grade components in Tape & Reel packaging format, suitable for high-volume automated assembly processes.

AD7280AWBSTZ-RL is appropriate for applications requiring automotive-grade qualification or when Cut Tape and Digi-Reel packaging configurations align with procurement and assembly workflows. The automotive-grade designation indicates enhanced reliability screening and qualification per automotive standards.

Both parts maintain ROHS3 compliance, identical MSL ratings, and full parametric equivalence across all battery monitoring functions. Selection does not impact circuit design, firmware implementation, or PCB layout requirements.

Frequently Asked Questions (FAQ)

Q: Can AD7280AWBSTZ-RL be used as a direct replacement for AD7280ABSTZ-RL in existing designs?

A: Yes. Both parts are parametrically equivalent across all functional, electrical, and environmental specifications. No design changes, firmware modifications, or PCB layout adjustments are required. The substitute part operates identically within the same operating temperature range and provides equivalent battery monitoring performance for 1 to 6 cell Lithium Ion packs.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for high-speed automated pick-and-place assembly. Cut Tape & Digi-Reel packaging provides the same components on cut tape segments or alternative reel formats, suitable for lower-volume production runs or alternative assembly equipment configurations. Both packaging formats contain identical components with no functional differences.

Q: Does the automotive-grade designation of AD7280AWBSTZ-RL impose additional requirements?

A: The automotive-grade designation indicates the part has undergone enhanced reliability screening and qualification per automotive industry standards. This designation does not impose additional design or application requirements. It reflects manufacturing process controls and quality assurance levels. Standard-grade and automotive-grade variants are functionally and electrically identical.

Q: Are there any compatibility concerns when switching between these part numbers?

A: No compatibility concerns exist. Both parts use identical 48-LQFP (7x7mm) Surface Mount packaging, SPI interface protocol, and electrical specifications. PCB footprints, signal routing, and firmware implementations remain unchanged. Substitution is transparent to circuit design and system operation.

Q: What inventory considerations apply to these substitute parts?

A: AD7280ABSTZ-RL maintains 802 pieces in stock. AD7280AWBSTZ-RL maintains 3293 pieces in stock. The substitute part offers significantly higher inventory availability, providing supply chain flexibility and reduced lead times for procurement planning.
