Infineon's IRPS5401MTRPBF is in critical shortage across global distribution channels. Factory lead time has blown out to January 2027. A new price increase took effect April 1, 2026. There is no pin-to-pin alternative. If this part is on your BOM, the window to secure stock at pre-increase pricing is closing fast.

What Is the IRPS5401MTRPBF?

The IRPS5401MTRPBF is Infineon's highly integrated Power Management IC (PMIC) — a single chip delivering 5 output rails for FPGAs, ASICs, SoCs, and other multi-rail power architectures.

Parameter	Specification
Package	QFN-56 (7×7 mm), Tape & Reel
Input Voltage	1.2 V to 14 V
Integrated Outputs	4× Buck regulators (4 A, 4 A, 2 A, 2 A) + 1× LDO
Max Output Current	50 A (with external power stage)
Interface	I²C + PMBus
Operating Temperature	-40 °C to +125 °C
Reel Quantity	3,000 pcs/reel

One chip replaces multiple discrete DC-DC converters — cutting board area by more than half. That's why it's designed into communications equipment, storage servers, embedded computing platforms, and high-density multi-rail systems. It's not a "nice-to-have." It's often the only practical option.

Current Market Reality: Out of Stock + Price Increase + No Alternative

1. Global Distribution — Out of Stock

As of April 2026, major authorized distributors show zero available inventory:

Distributor	Stock Status	Notes
Mouser	Out of Stock	Factory lead time shown as 5 weeks (actual queue far longer)
Digi-Key	Out of Stock	Part marked Active, zero inventory
Arrow	Out of Stock	Quote required for lead time

2. Factory Lead Time: January 2027

The Infineon Developer Community confirmed on April 1, 2026: IRPS5401MTRPBF lead time has been extended to January 2027. This is not a channel-specific delay — it's a systemic shortage driven by AI data center demand consuming Infineon's PMIC production capacity.

3. Infineon Price Increase — Effective April 1, 2026

Infineon has implemented a new round of price increases effective April 1, 2026. Both TrendForce and Tom's Hardware have reported on this: the rapid buildout of AI data centers has led to shortages across multiple Infineon product lines, and all new orders placed on or after April 1 are subject to the new pricing.

4. No Pin-to-Pin Alternative

This is the most critical factor. The IRPS5401MTRPBF's integration level — 5 outputs, built-in power sequencer, dual I²C/PMBus interface, 7×7 mm footprint — means no pin-to-pin compatible substitute currently exists on the market.

For products already in production, switching to an alternative means:

• Redesigning the power section PCB layout
• Re-running EMC compliance testing
• Re-qualifying the production line
• 3–6 months minimum total cycle time

Bottom line: if your product uses the IRPS5401MTRPBF, the cost of redesigning far exceeds the cost of securing stock now.

Why Is This Happening?

Three words: AI, data centers, capacity squeeze.

• AI server shipments projected to grow 65–80% YoY in 2026 (Sourceability Q4 2025 Report)
• Each AI server requires 3–5× more power management ICs than a traditional server
• Infineon is prioritizing capacity for tier-1 customers and automotive/industrial-grade products
• Communications and embedded computing PMIC allocation has been severely compressed

This is not a short-term fluctuation. It's a structural shortage. Until the AI compute buildout cycle stabilizes, power management IC availability will remain tight.

Is This Part on Your BOM?

If your products fall into any of these categories, there's a good chance the IRPS5401MTRPBF is on your BOM:

• ???? Communications equipment — 5G base stations, optical transceivers, switches
• ???? Storage servers — NAS, SAN, SSD controller boards
• ???? Embedded computing — industrial control boards, edge computing gateways
• ⚡ FPGA / ASIC boards — Xilinx / Intel FPGA power solutions
• ???? Multi-rail power systems — any board requiring 3+ voltage rails

Recommended Actions

1. Audit your BOM now — confirm which products use the IRPS5401MTRPBF and how long current inventory will last
2. Recalculate safety stock — with a 9-month factory lead time, a minimum 6-month buffer is strongly recommended
3. Don't wait — this is a structural shortage. By the time your production line actually runs out, the market may have nothing left to offer
