INA302A2IPWR Equivalent & Substitute Parts

Part Overview

The INA302A2IPWR is an active current sense regulator IC designed for high/low-side current sensing applications. Manufactured by Texas Instruments, this component operates across a 0V to 36V input voltage range and is housed in a 14-TSSOP surface mount package. The part is currently in active production status with ROHS3 compliance and MSL 2 moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications, package dimensions, and functional characteristics align with the main part number, enabling direct replacement in circuit designs without functional degradation.

Substitute Part Grouping Explanation

Substitute parts for the INA302A2IPWR are qualified based on the following criteria:

Electrical Equivalence: All substitute parts maintain identical input voltage range (0V ~ 36V), operating temperature range (-40°C ~ 125°C), and high/low-side current sensing functionality.

Package Compatibility: All substitutes use the 14-TSSOP package with identical 0.173" (4.40mm) width specification, ensuring mechanical and thermal compatibility with existing PCB layouts.

Compliance Alignment: All parts maintain ROHS3 compliance, MSL 2 rating, and active product status, confirming ongoing manufacturer support and supply chain viability.

Packaging Variants: Substitutes are available in different distribution formats (Tape & Reel or Cut Tape & Digi-Reel®) to accommodate various procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status with Texas Instruments, confirming ongoing design support and manufacturing availability. ROHS3 compliance across all variants ensures regulatory alignment for industrial, automotive, and consumer applications. MSL 2 moisture sensitivity rating applies uniformly, requiring standard moisture control during storage and assembly.

Selection between INA302A1IPWR, INA302A3IPWR, and INA303A1IPWR should be based on packaging format requirements: Tape & Reel (TR) for high-volume automated assembly, or Cut Tape (CT) & Digi-Reel® for lower-volume or mixed-component procurement workflows. The INA303A1IPWR represents a base product variant within the INA303 series while maintaining identical electrical and thermal specifications.

Frequently Asked Questions (FAQ)

Q: Can INA302A1IPWR replace INA302A2IPWR in existing designs? A: Yes. Both parts share identical electrical specifications, input voltage range (0V ~ 36V), operating temperature (-40°C ~ 125°C), and 14-TSSOP package dimensions. The difference is packaging format: INA302A2IPWR uses Tape & Reel, while INA302A1IPWR uses Cut Tape & Digi-Reel®.

Q: What is the difference between INA302 and INA303 series parts? A: Both series provide high/low-side current sensing with identical voltage input range and operating temperature specifications. The INA303A1IPWR represents the INA303 base product variant. Electrical and thermal performance remain equivalent for the specified parameter set.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 2 moisture sensitivity rating, meeting regulatory requirements for restricted substance use.

Q: Does packaging format affect electrical performance? A: No. Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® are distribution formats only. Electrical specifications, thermal performance, and functional characteristics remain identical regardless of packaging type.

Q: What inventory levels are available for each substitute? A: INA302A2IPWR: 7344 Pcs; INA302A1IPWR: 6200 Pcs; INA302A3IPWR: 1551 Pcs; INA303A1IPWR: 2651 Pcs. Inventory levels are subject to change based on supply and demand.
