AC0201FR-07348RL Equivalent & Substitute Parts

Part Overview

The AC0201FR-07348RL is a 348 Ohm ±1% thick film chip resistor in 0201 package (0.60mm × 0.30mm) rated at 0.05W (1/20W) power dissipation. This YAGEO component is manufactured to automotive AEC-Q200 standards with moisture-resistant construction and operates across -55°C to 155°C. The part is currently active in production with 898 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when supply chain optimization is required, or when design flexibility across multiple qualified manufacturers is needed while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the AC0201FR-07348RL is determined by strict equivalence across the following critical parameters:

Resistance value: 348 Ohms
Tolerance: ±1%
Power rating: 0.05W (1/20W)
Package: 0201 (0603 Metric)
Composition: Thick Film
Temperature coefficient: ±200ppm/°C
Physical dimensions: 0.024" L × 0.012" W (0.60mm × 0.30mm)
Termination count: 2
RoHS and REACH compliance status

All substitute parts listed meet these core electrical and mechanical requirements. Variations in operating temperature range, product status, or optional features (such as automotive certification) are noted but do not disqualify substitution when the primary electrical and mechanical parameters align.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Temperature Range)

RC0201FR-07348RL (YAGEO) and CRCW0201348RFNED (Vishay Dale) are direct functional equivalents with active product status. RC0201FR-07348RL operates to -55°C to 125°C, which is suitable for most applications within the primary part's range. CRCW0201348RFNED maintains the full -55°C to 155°C operating range and is recommended when maximum temperature coverage is required.

Secondary Substitutes (Active Status, Reduced Temperature Range)

ERJ-1GNF3480C (Panasonic) is active and functionally equivalent with -55°C to 125°C operating range. This part is suitable for applications not requiring the extended upper temperature limit of 155°C.

Legacy Substitute (Not For New Designs)

RK73H1HTTC3480F (KOA Speer Electronics) meets all electrical and mechanical parameters but carries "Not For New Designs" status. This part is suitable only for legacy system maintenance or replacement in existing production lines where continuity is required.

Stackpole Alternative

RMCF0201FT348R (Stackpole Electronics) is functionally equivalent with active status and full temperature range. Physical height is 0.28mm versus 0.26mm maximum for other parts; this minor variation does not affect PCB assembly compatibility for standard 0201 package designs.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC0201FR-07348RL for AC0201FR-07348RL in applications requiring -55°C to 155°C operation?

A: RC0201FR-07348RL operates to -55°C to 125°C. If your application requires sustained operation above 125°C, use CRCW0201348RFNED or RMCF0201FT348R instead, both rated to 155°C.

Q: What is the difference between the YAGEO AC and RC series?

A: Both AC0201FR-07348RL and RC0201FR-07348RL are YAGEO 348 Ohm 0201 resistors with ±1% tolerance and 0.05W rating. The AC series includes automotive AEC-Q200 certification and moisture-resistant features. The RC series provides moisture resistance without automotive certification. Operating temperature range differs: AC extends to 155°C, RC to 125°C.

Q: Is RK73H1HTTC3480F suitable for new designs?

A: RK73H1HTTC3480F carries "Not For New Designs" status. For new designs, select from active parts: RC0201FR-07348RL, CRCW0201348RFNED, RMCF0201FT348R, or ERJ-1GNF3480C.

Q: Do all substitute parts fit the same PCB footprint?

A: Yes. All parts use 0201 package (0.60mm × 0.30mm) with 2 terminations. RMCF0201FT348R has maximum seated height of 0.28mm versus 0.26mm for others; this does not affect standard 0201 footprint compatibility.

Q: Which substitute offers the best supply availability?

A: ERJ-1GNF3480C (Panasonic) has 60,538 units in stock. RC0201FR-07348RL (YAGEO) has 85,557 units. CRCW0201348RFNED (Vishay Dale) has 15,516 units. Verify current inventory with your supplier.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant and REACH unaffected.
