AC0201FR-07124RL Equivalent & Substitute Parts

Part Overview

The AC0201FR-07124RL is a 124 Ohms ±1% thick film chip resistor manufactured by YAGEO in the 0201 (0603 Metric) package format. This component is rated for 0.05W (1/20W) power dissipation and meets AEC-Q200 automotive qualification standards with moisture-resistant construction. The part is currently in active production status with 870 pieces available in inventory.

Substitute parts are necessary when the primary manufacturer experiences supply constraints, lead time extensions, or when design requirements mandate alternative qualified sources for supply chain resilience and cost optimization.

Substitute Part Grouping Explanation

Substitution eligibility for the AC0201FR-07124RL is determined by strict equivalence across the following critical parameters:

• Resistance value: 124 Ohms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package format: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

All substitute parts listed maintain identical electrical and mechanical specifications across these parameters, ensuring direct functional interchangeability in circuit applications without design modification or re-qualification.

Engineering Selection Recommendations

AC0201FR-07124RL (YAGEO) — Primary selection for new designs. Active product status with continuous manufacturing support. Carries AEC-Q200 automotive qualification and moisture-resistant construction. Recommended for applications requiring long-term supply availability and automotive-grade reliability.

CRCW0201124RFNED (Vishay Dale) — Qualified alternative for new designs. Active product status ensures ongoing availability. Meets all electrical and mechanical specifications. Suitable for applications where dual-source qualification is required or when YAGEO supply is constrained.

RK73H1HTTC1240F (KOA Speer) — Legacy substitute only. Marked as "Not For New Designs" by manufacturer. Carries AEC-Q200 automotive qualification and meets all electrical specifications. Use only for replacement, repair, or maintenance of existing assemblies where original part sourcing is unavailable.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTC1240F be used in new product designs? A: No. This part is designated "Not For New Designs" by KOA Speer Electronics. It is suitable only for replacement or repair of existing assemblies. New designs should use AC0201FR-07124RL or CRCW0201124RFNED.

Q: Are all three parts electrically identical? A: Yes. All three parts share identical resistance (124 Ohms), tolerance (±1%), power rating (0.05W), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C ~ 155°C).

Q: Do all substitute parts fit the same PCB footprint? A: Yes. All parts use the 0201 (0603 Metric) package with identical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm).

Q: Are all parts AEC-Q200 qualified? A: AC0201FR-07124RL and RK73H1HTTC1240F carry AEC-Q200 automotive qualification. CRCW0201124RFNED does not list AEC-Q200 rating in provided specifications.

Q: What is the moisture sensitivity level for these parts? A: All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are all parts RoHS3 compliant? A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected.
