Substitute Part Grouping Explanation

Substitute parts for the INA302A1IPWR are identified based on strict parameter alignment across the following critical criteria:

Electrical Parameters:

• Function: Current Sense
• Sensing Method: High/Low-Side
• Voltage - Input Range: 0V ~ 36V
• Operating Temperature Range: -40°C ~ 125°C

Mechanical Parameters:

• Package / Case: 14-TSSOP (0.173", 4.40mm Width)
• Supplier Device Package: 14-TSSOP
• Mounting Type: Surface Mount

Compliance & Status:

• Manufacturer: Texas Instruments
• Product Status: Active
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 2 (1 Year)
• REACH Status: REACH Unaffected

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Packaging format variations (Cut Tape vs. Tape & Reel) do not affect electrical or mechanical compatibility and represent supply chain options only.

Parameter Comparison

Engineering Selection Recommendations

All three parts—INA302A1IPWR, INA302A3IPWR, and INA303A1IPWR—meet identical electrical and mechanical specifications for current sensing applications. Selection between these parts is determined by:

Product Availability: Inventory levels vary across part numbers. INA302A1IPWR maintains 6200 units in stock, INA302A3IPWR provides 1551 units, and INA303A1IPWR offers 2651 units.

Packaging Format: INA302A1IPWR and INA303A1IPWR are supplied in Cut Tape (CT) & Digi-Reel® format, while INA302A3IPWR is supplied in Tape & Reel (TR) format. Packaging selection depends on assembly process requirements and volume handling capabilities.

Compliance Status: All parts maintain Active product status, ROHS3 compliance, and REACH Unaffected designation, ensuring regulatory alignment for current applications.

Base Product Series: INA302A1IPWR and INA302A3IPWR share the INA302 base product number, while INA303A1IPWR uses the INA303 base product number. Both series are functionally equivalent for the specified application parameters.

Frequently Asked Questions (FAQ)

Q: Can INA302A3IPWR directly replace INA302A1IPWR in production?

A: Yes. Both parts share identical electrical parameters (0V ~ 36V input, -40°C ~ 125°C operating range, High/Low-Side sensing), mechanical specifications (14-TSSOP package), and compliance certifications (ROHS3, REACH Unaffected). The difference is packaging format: INA302A1IPWR uses Cut Tape & Digi-Reel®, while INA302A3IPWR uses Tape & Reel. Assembly process compatibility determines suitability.

Q: What is the difference between INA302A1IPWR and INA303A1IPWR?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The primary distinction is the base product series: INA302 versus INA303. Both function as High/Low-Side current sense regulators across 0V ~ 36V input range with 14-TSSOP packaging. Selection depends on availability and supply chain requirements.

Q: Does packaging format affect circuit performance?

A: No. Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) formats represent supply chain and assembly process options only. Electrical and mechanical performance remains identical. Selection is based on manufacturing equipment compatibility and volume handling requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. INA302A1IPWR, INA302A3IPWR, and INA303A1IPWR are all ROHS3 compliant with Moisture Sensitivity Level 2 (1 Year) and REACH Unaffected status, meeting current regulatory requirements for electronic components.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the circuit design accommodates the 14-TSSOP package footprint and the assembly process supports the selected packaging format. All three parts maintain identical pin configuration, electrical ratings, and functional specifications for current sensing applications.
