TPS61301YFFR Equivalent & Substitute Parts

Part Overview

The TPS61301YFFR is an active LED driver IC manufactured by Texas Instruments, designed for camera flash applications. This power management IC integrates a 3-output DC-DC step-up (boost) regulator with I2C-based dimming control, delivering 400mA standard output or 800mA in flash mode. The device operates from a 2.5V to 5.5V supply and generates a 5.7V output across its three channels in a 20-DSBGA surface mount package.

As an active product with ROHS3 compliance and unlimited moisture sensitivity rating, the TPS61301YFFR remains in full production. Equivalent and substitute parts are identified for design flexibility, inventory management, and supply chain continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the TPS61301YFFR is determined by strict parametric equivalence across the following critical criteria:

Electrical Parameters (Must Match):

Supply voltage range: 2.5V to 5.5V
Output voltage: 5.7V
Output current per channel: 400mA standard, 800mA flash mode
Switching frequency: 1.92MHz
Number of outputs: 3
Dimming interface: I2C

Mechanical & Environmental Parameters (Must Match):

Package type: 20-DSBGA (20-UFBGA)
Mounting type: Surface Mount
Operating temperature range: -40°C to 85°C
Moisture sensitivity level: 1 (Unlimited)

Compliance & Status (Must Match):

Product status: Active
RoHS compliance: ROHS3 Compliant
REACH status: REACH Unaffected

All identified substitute parts meet these criteria without exception. Substitution is based solely on parametric equivalence; no functional testing or design verification is required beyond standard component qualification procedures.

Engineering Selection Recommendations

All identified substitute parts are active products with full ROHS3 compliance and REACH unaffected status. Selection among TPS61301YFFR, TPS61300YFFR, TPS61300YFFT, TPS61301YFFT, and TPS61305YFFR is determined by packaging specification and inventory availability.

Packaging Differentiation:

TPS61301YFFR and TPS61305YFFR: Tape & Reel (TR) packaging
TPS61300YFFR: Tape & Reel (TR) packaging
TPS61300YFFT and TPS61301YFFT: Tape & Reel (TR) packaging

All parts share identical electrical, thermal, and environmental specifications. Component selection should prioritize supply chain availability and lead time requirements. No design modifications are required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can TPS61300YFFR be used as a direct replacement for TPS61301YFFR?

A: Yes. Both parts are parametrically equivalent across all electrical, mechanical, and environmental specifications. The base product numbers differ (TPS61300 vs. TPS61301), but all critical parameters including supply voltage, output voltage, current ratings, switching frequency, I2C dimming control, package type, and operating temperature range are identical.

Q: What is the difference between YFFR and YFFT packaging designations?

A: Both designations indicate Tape & Reel (TR) packaging for surface mount components. The suffix variation reflects manufacturing or distribution batch coding. Electrical and mechanical specifications remain identical.

Q: Are all substitute parts suitable for camera flash applications?

A: Yes. All identified substitute parts are specified for camera flash applications with identical 400mA standard output and 800mA flash mode current delivery across three output channels.

Q: Do substitute parts require PCB layout modifications?

A: No. All substitute parts use the identical 20-DSBGA package footprint. PCB layouts, trace routing, and component placement remain unchanged.

Q: What is the significance of the TPS61305 variant?

A: TPS61305YFFR maintains full parametric equivalence with TPS61301YFFR. The base product number variation (TPS61305 vs. TPS61301) does not affect electrical performance, output specifications, or application suitability.

Q: Are moisture sensitivity considerations different among substitute parts?

A: No. All substitute parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.
