Substitute Part Grouping Explanation

Substitution eligibility for the CRCW12061R40FNTA is determined by strict equivalence across the following critical parameters:

Resistance value: 1.4 Ohms
Tolerance: ±1%
Power rating: 0.25W (1/4W)
Package: 1206 (3216 Metric)
Composition: Thick Film
Temperature coefficient: ±200ppm/°C
Operating temperature range: -55°C ~ 155°C
Number of terminations: 2

All qualified substitutes maintain identical electrical specifications and mechanical compatibility. Physical dimensions may vary within acceptable tolerances for the 1206 package footprint. Compliance certifications and RoHS status may differ between manufacturers but do not affect functional interchangeability in applications where the main part is specified.

Engineering Selection Recommendations

All four parts are electrically and mechanically equivalent for applications requiring a 1.4 Ohm ±1% 0.25W 1206 thick film resistor. Selection among these alternatives should be based on the following criteria:

RMCF1206FT1R40 (Stackpole Electronics Inc) is suitable for applications where AEC-Q200 automotive qualification is required and RoHS3 compliance is mandated. This part offers the highest inventory availability at 19,882 pieces.

AC1206FR-071R4L (YAGEO) provides both AEC-Q200 automotive qualification and moisture-resistant construction with RoHS3 compliance. This part is recommended for applications requiring enhanced environmental protection.

RC1206FR-071R4L (YAGEO) offers moisture-resistant construction and RoHS3 compliance. This part is suitable for applications where moisture resistance is a design requirement, though AEC-Q200 automotive qualification is not specified.

CRCW12061R40FNTA (Vishay Dale) maintains AEC-Q200 qualification but does not meet RoHS3 compliance. This part remains the primary choice for legacy designs or applications where RoHS exemptions apply.

Frequently Asked Questions (FAQ)

Q: Can RMCF1206FT1R40 be used as a direct replacement for CRCW12061R40FNTA?

A: Yes. Both parts meet identical electrical specifications (1.4 Ohms ±1%, 0.25W, ±200ppm/°C, -55°C ~ 155°C) and are packaged in 1206 (3216 Metric) thick film construction. Both carry AEC-Q200 automotive qualification. Physical dimensions are within acceptable tolerances for the 1206 package footprint.

Q: What is the difference between AC1206FR-071R4L and RC1206FR-071R4L?

A: Both are YAGEO 1206 thick film resistors with identical electrical specifications. AC1206FR-071R4L includes AEC-Q200 automotive qualification; RC1206FR-071R4L does not specify this certification. Both include moisture-resistant construction and RoHS3 compliance.

Q: Are there any height restrictions when substituting these parts?

A: The main part CRCW12061R40FNTA has a maximum seated height of 0.024" (0.60mm). Substitute parts range from 0.026" to 0.028" (0.65mm to 0.70mm) maximum height. Verify that PCB assembly equipment and design clearances accommodate the taller profile of substitute parts.

Q: Which substitute part has the best inventory availability?

A: RMCF1206FT1R40 (Stackpole Electronics Inc) has 19,882 pieces in stock, significantly higher than other alternatives.

Q: Do all substitute parts meet RoHS3 compliance?

A: RMCF1206FT1R40, AC1206FR-071R4L, and RC1206FR-071R4L are all RoHS3 compliant. The original CRCW12061R40FNTA is RoHS non-compliant.

Q: Which substitute part is recommended for moisture-sensitive applications?

A: AC1206FR-071R4L and RC1206FR-071R4L both feature moisture-resistant construction. AC1206FR-071R4L additionally carries AEC-Q200 automotive qualification.
