Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RMC1/8-2214FTP are qualified based on the following critical parameters:

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

Mechanical Compatibility: Package type 1206 (3216 Metric) with identical footprint dimensions (0.122" L x 0.063" W / 3.10mm x 1.60mm) and two terminations.

Environmental Ratings: Operating temperature range of -55°C ~ 155°C and MSL 1 classification.

Packaging Format: Tape & Reel (TR) configuration for automated assembly compatibility.

Compliance: REACH Unaffected and EAR99 ECCN classification.

Substitute parts meeting all these criteria are electrically and mechanically interchangeable with the main part in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-072M21L (YAGEO) is a direct substitute for RMC1/8-2214FTP. Both parts share identical electrical specifications (2.21 MOhms ±1%, 0.25W), mechanical dimensions (1206 package), and environmental ratings (-55°C ~ 155°C, MSL 1).

The RC1206FR-072M21L offers improved temperature coefficient performance (±100ppm/°C versus ±200ppm/°C), which provides enhanced stability across the operating temperature range. The YAGEO part includes moisture-resistant thick film composition and carries ROHS3 compliance certification.

Both parts are Active product status with REACH Unaffected and EAR99 ECCN classification, confirming regulatory compliance for general industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-072M21L replace RMC1/8-2214FTP in existing designs?

A: Yes. Both parts have identical resistance (2.21 MOhms), tolerance (±1%), power rating (0.25W), package (1206), and operating temperature range (-55°C ~ 155°C). Mechanical footprint and termination count are identical, enabling direct substitution in PCB layouts.

Q: What is the difference in temperature coefficient between these parts?

A: RMC1/8-2214FTP has ±200ppm/°C temperature coefficient, while RC1206FR-072M21L has ±100ppm/°C. The YAGEO part exhibits superior temperature stability, resulting in lower resistance drift across the -55°C ~ 155°C operating range.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both RMC1/8-2214FTP and RC1206FR-072M21L are supplied in Tape & Reel (TR) format, compatible with automated pick-and-place assembly equipment.

Q: Do these parts have the same moisture sensitivity rating?

A: Yes. Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What compliance certifications apply to both parts?

A: Both parts are REACH Unaffected and classified as EAR99 under ECCN. The RC1206FR-072M21L additionally carries ROHS3 compliance certification.

Q: Are the physical dimensions identical?

A: Dimensions are functionally identical. Both measure 0.122" L x 0.063" W (3.10mm x 1.60mm). Maximum seated height is 0.025" (0.65mm) for RMC1/8-2214FTP and 0.026" (0.65mm) for RC1206FR-072M21L, a negligible difference within standard PCB assembly tolerances.
