TC1303C-PA0EMF Equivalent & Substitute Parts

Part Overview

The TC1303C-PA0EMF is a dual-output PMIC (Power Management Integrated Circuit) from Microchip Technology designed for applications requiring synchronized step-down buck regulation and linear LDO output. This device integrates a 2MHz switching frequency buck converter with a linear regulator in a compact 10-DFN surface mount package. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified based on identical electrical specifications, topology, and package configuration to ensure direct functional equivalence in system designs.

Substitute Part Grouping Explanation

Substitute parts for the TC1303C-PA0EMF are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Equivalence Requirements:

• Identical dual-output topology: Step-Down (Buck) Synchronous (1) and Linear (LDO) (1)
• Matching output voltage and current specifications: 1.8V/500mA and 3.3V/300mA
• Identical switching frequency: 2MHz
• Matching supply voltage range: 2.7V ~ 5.5V
• Identical operating temperature range: -40°C ~ 85°C

Mechanical & Packaging Equivalence Requirements:

• Same package type: 10-VFDFN Exposed Pad
• Same mounting type: Surface Mount
• Same supplier device package: 10-DFN (3x3)

Compliance & Status Requirements:

• Active product status
• RoHS3 compliance
• MSL 1 rating

The identified substitute differs only in packaging format (Tube vs. Tape & Reel), which does not affect electrical or mechanical compatibility in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the TC1303C-PA0EMF and TC1303C-PA0EMFTR are active production parts with full RoHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts is determined by procurement and assembly requirements rather than electrical performance:

TC1303C-PA0EMF (Tube Packaging): Suitable for low-volume applications, prototype development, and manual assembly processes where individual component handling is required.

TC1303C-PA0EMFTR (Tape & Reel Packaging): Suitable for high-volume production runs and automated pick-and-place assembly operations where continuous tape feeding is required.

Both parts maintain identical electrical characteristics, thermal performance, and regulatory compliance. The choice between them does not affect circuit design, PCB layout, or system functionality.

Frequently Asked Questions (FAQ)

Q: Can TC1303C-PA0EMFTR be used as a direct replacement for TC1303C-PA0EMF?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Reel vs. Tube). They are pin-compatible, have identical electrical specifications, and require no circuit modifications.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging contains individual components in a plastic tube suitable for manual handling and low-volume assembly. Tape & Reel packaging places components on continuous carrier tape in reels, optimized for automated assembly equipment. Both formats contain the same die and provide identical performance.

Q: Are there any thermal or reliability differences between these parts?

A: No. Both parts share identical thermal characteristics, operating temperature range (-40°C ~ 85°C), and reliability ratings. Packaging format does not affect thermal performance or long-term reliability.

Q: Can these parts be mixed in the same production batch?

A: Yes, provided your assembly process can accommodate both packaging formats. However, mixing formats typically increases handling complexity and is not recommended for high-volume automated assembly.

Q: What certifications apply to both substitute parts?

A: Both parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.
