Substitute Part Grouping Explanation

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

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

The substitute parts identified below meet all of these criteria and are therefore electrically and mechanically interchangeable with the AC0201FR-07124KL in applications where the specified parameters are required.

Parameter Comparison

Engineering Selection Recommendations

AC0201FR-07124KL (YAGEO) — Primary selection for new designs. Active production status with automotive AEC-Q200 qualification and moisture-resistant construction. Current inventory: 969 units.

RK73H1HTTC1243F (KOA Speer Electronics) — Qualified substitute with full electrical and mechanical equivalence. Carries AEC-Q200 automotive rating and moisture-resistant features. Product status is "Not For New Designs," indicating this part is in mature or declining production phase. Suitable for replacement applications or when YAGEO supply is unavailable. Current inventory: 11,573 units.

CRCW0201124KFNED (Vishay Dale) — Qualified substitute with full electrical and mechanical equivalence. Active production status. Suitable for new designs as an alternative source. Current inventory: 2,928 units.

All three parts maintain identical electrical performance, thermal characteristics, and physical dimensions. Selection between active-status parts (YAGEO and Vishay Dale) is based on availability, lead time, and supply chain requirements. The KOA Speer part remains functionally equivalent but is designated for replacement applications only.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTC1243F be used as a direct replacement for AC0201FR-07124KL?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (124 kOhms ±1%), power rating (0.05W), package format (0201), temperature coefficient (±200ppm/°C), and operating range (-55°C ~ 155°C). The primary difference is product status; RK73H1HTTC1243F is designated "Not For New Designs."

Q: What is the difference between CRCW0201124KFNED and the other substitutes?

A: CRCW0201124KFNED is electrically and mechanically identical to both AC0201FR-07124KL and RK73H1HTTC1243F. The key distinction is that CRCW0201124KFNED maintains active production status, making it suitable for new design implementations alongside the YAGEO part.

Q: Are all three parts AEC-Q200 qualified?

A: AC0201FR-07124KL and RK73H1HTTC1243F both carry explicit AEC-Q200 automotive qualification. CRCW0201124KFNED does not list AEC-Q200 in its feature set, indicating it may not meet automotive qualification requirements for applications where this certification is mandatory.

Q: Can these parts be used interchangeably in automotive applications?

A: AC0201FR-07124KL and RK73H1HTTC1243F are both AEC-Q200 qualified and suitable for automotive use. CRCW0201124KFNED lacks stated AEC-Q200 qualification and should not be substituted in applications where automotive certification is a design requirement.

Q: What is the significance of the 0201 package format?

A: The 0201 (0603 Metric) package is a surface-mount format measuring 0.024" L x 0.012" W (0.60mm x 0.30mm). All three parts use this identical package, ensuring mechanical compatibility with PCB layouts and pick-and-place equipment designed for 0201 components.

Q: Are moisture sensitivity considerations the same across all three parts?

A: Yes. All three parts carry Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
