AC0201FR-0748K7L Equivalent & Substitute Parts

Part Overview

The AC0201FR-0748K7L is a 48.7 kOhms ±1% thick film chip resistor in 0201 package format, rated at 0.05W (1/20W) power dissipation. Manufactured by YAGEO under the AC series, this component is designed for automotive applications with AEC-Q200 qualification and moisture-resistant construction. The part is currently in active production status with 722 units in stock.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements allow for alternative manufacturers meeting equivalent electrical and mechanical specifications. All substitute parts listed maintain identical resistance value, tolerance, power rating, package dimensions, and compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Resistance value: 48.7 kOhms
Tolerance: ±1%
Power rating: 0.05W (1/20W)
Package format: 0201 (0603 Metric)
Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
Composition: Thick Film
Temperature coefficient: ±200ppm/°C
RoHS3 compliance
MSL rating: 1 (Unlimited)

All substitute parts meet these core electrical and mechanical requirements. Differences in operating temperature range, packaging format (Tape & Reel vs. Cut Tape), and product status are noted but do not affect functional interchangeability in standard applications.

Engineering Selection Recommendations

Primary Selection (AC0201FR-0748K7L): Recommended for new automotive designs requiring AEC-Q200 qualification. This part offers the widest operating temperature range (-55°C to 155°C) and active production status with established supply availability.

Alternative Selection (RC0201FR-0748K7L): YAGEO alternative within the same manufacturer family. Suitable for applications with operating temperature requirements up to 125°C. Offers higher inventory availability (43,852 units) and Cut Tape packaging option.

Cross-Manufacturer Alternatives:

CRCW020148K7FNED (Vishay Dale): Maintains full -55°C to 155°C operating range with active status. Suitable for designs without automotive-specific requirements.
ERJ-1GNF4872C (Panasonic): Active production with highest inventory availability (445,283 units). Operating temperature limited to -55°C to 125°C. Recommended for high-volume procurement scenarios.
RK73H1HTTC4872F (KOA Speer): Marked "Not For New Designs." Suitable only for legacy system maintenance or existing design continuity where supply exists (16,652 units available).

Frequently Asked Questions (FAQ)

Q: Can RC0201FR-0748K7L replace AC0201FR-0748K7L in automotive applications?

A: RC0201FR-0748K7L is electrically equivalent but lacks AEC-Q200 automotive qualification. It is suitable for non-automotive applications or designs where automotive certification is not required. Operating temperature range is limited to -55°C to 125°C versus the AC series' -55°C to 155°C.

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

A: Both packaging formats contain identical components. Tape & Reel (TR) is supplied on continuous tape for automated assembly lines. Cut Tape (CT) is supplied in shorter tape segments. Selection depends on assembly equipment compatibility and order quantity requirements.

Q: Is RK73H1HTTC4872F still recommended for new designs?

A: No. This part carries "Not For New Designs" status. It remains available for existing design support and legacy system maintenance only. For new designs, select from AC0201FR-0748K7L, RC0201FR-0748K7L, CRCW020148K7FNED, or ERJ-1GNF4872C.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All listed parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly and storage conditions.

Q: Which substitute offers the best supply availability?

A: ERJ-1GNF4872C (Panasonic) provides the highest inventory level at 445,283 units. This part is recommended for high-volume production scenarios where supply security is a priority.

Q: Are there temperature range limitations I should consider?

A: The AC0201FR-0748K7L and CRCW020148K7FNED support -55°C to 155°C operation. RC0201FR-0748K7L and ERJ-1GNF4872C are limited to -55°C to 125°C. Verify your application's maximum operating temperature before selection.
