Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RMCF1206FT2M21 are qualified based on the following criteria:

Electrical Equivalence: Resistance value of 2.21 MOhms with ±1% tolerance and 0.25W power rating must be maintained.

Package Compatibility: All substitutes must use the 1206 (3216 Metric) surface mount package with two terminations.

Environmental Specifications: Operating temperature range of -55°C to 155°C and MSL 1 rating are required.

Compliance Requirements: RoHS3 compliance and REACH unaffected status must be present.

Composition: Thick film construction is the specified technology.

The identified substitutes meet all these criteria. Temperature coefficient variations (±200ppm/°C vs ±100ppm/°C) and minor dimensional differences in height and length fall within acceptable tolerances for this component category and do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status with full RoHS3 compliance and REACH unaffected designation. The CRCW12062M21FKEA from Vishay Dale carries automotive AEC-Q200 qualification matching the original RMCF1206FT2M21. The RC1206FR-072M21L from YAGEO features moisture-resistant construction and offers superior temperature coefficient stability at ±100ppm/°C compared to the original ±200ppm/°C specification. Selection between these substitutes depends on specific application requirements regarding automotive qualification and moisture resistance performance.

Frequently Asked Questions (FAQ)

Q: Can CRCW12062M21FKEA directly replace RMCF1206FT2M21 in automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification, maintain identical electrical specifications (2.21 MOhms ±1%, 0.25W), and use the 1206 package. The CRCW part offers improved temperature coefficient performance at ±100ppm/°C.

Q: What is the significance of the temperature coefficient difference between the original and substitutes?

A: The original RMCF1206FT2M21 specifies ±200ppm/°C while both substitutes specify ±100ppm/°C. The substitute parts provide tighter temperature stability, which is beneficial for precision applications but not required for functional equivalence.

Q: Is RC1206FR-072M21L suitable for moisture-sensitive applications?

A: The RC1206FR-072M21L includes moisture-resistant features and maintains MSL 1 rating. This part is suitable for applications requiring enhanced moisture protection beyond standard thick film construction.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: All three parts use the 1206 (3216 Metric) package. Minor variations exist in maximum seated height (0.028" for RMCF, 0.024" for CRCW, 0.026" for YAGEO) and length (0.126" for RMCF and CRCW, 0.122" for YAGEO). These differences are within standard PCB design tolerances and do not affect board-level compatibility.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. ECCN and HTSUS classifications are identical across all parts.
