Substitute Part Grouping Explanation

Substitution eligibility for the AC0201FR-07665KL is determined by strict equivalence across the following critical parameters:

• Resistance value: 665 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical requirements. Variations in operating temperature range and specific feature sets (such as automotive AEC-Q200 rating) are noted in the parameter comparison table below and do not preclude substitution where application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active production components with ROHS3 compliance and MSL 1 rating, confirming suitability for general electronic assembly and long-term storage without moisture sensitivity constraints.

The AC0201FR-07665KL and RMCF0201FT665K both carry AEC-Q200 automotive qualification and support the full -55°C to 155°C operating temperature range. These parts are preferred for automotive and high-reliability applications requiring extended temperature performance.

The RC0201FR-07665KL and ERJ-1GNF6653C operate within the -55°C to 125°C range, which is suitable for standard industrial and consumer applications where the extended upper temperature limit of 155°C is not required.

The CRCW0201665KFNED from Vishay Dale provides a cross-manufacturer alternative with identical electrical specifications and standard operating temperature range (-55°C to 155°C), offering supply chain diversification without performance compromise.

Selection should be based on application temperature requirements, automotive qualification needs, and procurement availability.

Frequently Asked Questions (FAQ)

Q: Can RC0201FR-07665KL replace AC0201FR-07665KL in all applications?

A: RC0201FR-07665KL is electrically and mechanically equivalent with identical resistance, tolerance, power rating, and package specifications. The operating temperature range differs: RC0201FR-07665KL operates to 125°C maximum versus 155°C for AC0201FR-07665KL. Substitution is valid for applications where the maximum operating temperature does not exceed 125°C. For automotive applications requiring AEC-Q200 qualification, AC0201FR-07665KL is preferred.

Q: What is the difference between AEC-Q200 rated and non-rated parts?

A: AEC-Q200 is an automotive qualification standard. AC0201FR-07665KL and RMCF0201FT665K carry this rating, indicating compliance with automotive reliability and quality requirements. Non-rated parts (RC0201FR-07665KL, CRCW0201665KFNED, ERJ-1GNF6653C) meet the same electrical and mechanical specifications but lack formal automotive qualification. Use AEC-Q200 rated parts for automotive applications; non-rated parts are suitable for industrial and consumer electronics.

Q: Are all substitute parts pin-compatible?

A: Yes. All parts use identical 0201 package (0603 Metric) with 2 terminations and matching physical dimensions (0.024" L x 0.012" W). Height variation is minimal: RMCF0201FT665K has a maximum seated height of 0.011" (0.28mm) versus 0.010" (0.26mm) for other parts. This difference is within standard PCB assembly tolerances and does not affect compatibility.

Q: Which substitute part has the best availability?

A: ERJ-1GNF6653C from Panasonic has the highest inventory at 29,380 units, followed by RC0201FR-07665KL (YAGEO) at 22,952 units. RMCF0201FT665K (Stackpole) has 10,797 units, and CRCW0201665KFNED (Vishay Dale) has 6,549 units in stock.

Q: Can I use CRCW0201665KFNED in place of AC0201FR-07665KL?

A: CRCW0201665KFNED is electrically and mechanically equivalent with identical resistance, tolerance, power rating, package, and operating temperature range (-55°C to 155°C). The primary difference is the absence of AEC-Q200 automotive qualification and moisture-resistant feature designation. Substitution is valid for non-automotive applications or where automotive qualification is not required.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life without moisture exposure precautions. All listed parts carry MSL 1 rating, eliminating moisture-related storage constraints and simplifying inventory management.
