Substitute Part Grouping Explanation

Substitution eligibility for the RMCF2010FT274R is determined by strict equivalence across the following parameters:

• Resistance value: 274 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.75W minimum (exact match required)
• Package: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C minimum (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

All identified substitute parts meet these criteria without exception. Substitution is valid only when all parameters align precisely with the main part specification.

Parameter Comparison

Engineering Selection Recommendations

RMCF2010FT274R (Stackpole Electronics Inc) — Primary selection. Active product status with full production support. ROHS3 compliant and AEC-Q200 qualified. Recommended for new designs and ongoing production.

AC2010FK-07274RL (YAGEO) — Preferred substitute. Active product status ensures long-term availability. Manufacturer-recommended alternative with identical electrical specifications. Additional moisture-resistant feature noted in composition. Seated height of 0.026" (0.65mm) is within tolerance for standard 2010 package applications. ROHS3 compliant and AEC-Q200 qualified.

ERJ-12SF2740U (Panasonic Electronic Components) — Secondary substitute. Product status is "Not For New Designs," indicating this part is in mature phase with limited future production commitment. Electrical and mechanical specifications are identical to the primary part. ROHS3 compliant and AEC-Q200 qualified. Suitable only for legacy design support or when primary and preferred substitutes are unavailable.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF2740U be used in new product designs? A: No. ERJ-12SF2740U carries a "Not For New Designs" status, indicating Panasonic has discontinued active development for this part. Use RMCF2010FT274R or AC2010FK-07274RL for new designs.

Q: Are all three parts electrically identical? A: Yes. All three parts share identical resistance (274 Ohms), tolerance (±1%), power rating (0.75W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C).

Q: Does the height difference between AC2010FK-07274RL (0.026") and the other parts (0.028") affect compatibility? A: No. Both measurements fall within the standard 2010 (5025 Metric) package specification. The 0.002" difference is within normal manufacturing tolerance and does not impact PCB assembly or circuit performance.

Q: Are all substitute parts AEC-Q200 qualified? A: Yes. RMCF2010FT274R, ERJ-12SF2740U, and AC2010FK-07274RL all meet AEC-Q200 automotive qualification standards.

Q: Can these parts be used interchangeably in automotive applications? A: Yes, provided the application requires 274 Ohm ±1% 0.75W thick film resistors in 2010 package with -55°C to 155°C operating range. All three parts are AEC-Q200 qualified and ROHS3 compliant.

Q: What is the difference between RMCF2010FT274R and AC2010FK-07274RL? A: Both are active products with identical electrical specifications. AC2010FK-07274RL includes a moisture-resistant feature and has a slightly lower seated height (0.026" vs 0.028"). AC2010FK-07274RL is the manufacturer-recommended substitute.
