Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F1214CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 1.21 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Operating temperature range: -55°C to 155°C
• Moisture Sensitivity Level: MSL 1
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Temperature coefficient: ±100ppm/°C to ±200ppm/°C (within industrial tolerance)
• Physical dimensions: Minor variations within 1206 package specification (length 3.10mm to 3.20mm, height 0.60mm to 0.70mm)
• Packaging format: Tape & Reel (TR) or Cut Tape (CT)
• Supplier device package designation: All variants use 1206

Three substitute parts meet these criteria with the following distinctions:

RC1206FR-071M21L (YAGEO): Direct equivalent with identical electrical specifications and moisture-resistant thick film composition. Packaged in Tape & Reel format.

RMCF1206FG1M21 (Stackpole Electronics Inc): Upgrade variant with automotive AEC-Q200 qualification. Temperature coefficient is ±200ppm/°C (versus ±100ppm/°C base). Packaged in Cut Tape format.

CRCW12061M21FKEA (Vishay Dale): Automotive AEC-Q200 qualified variant with ±100ppm/°C temperature coefficient matching the base part. Packaged in Tape & Reel format with highest inventory availability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Non-Automotive Applications): RC1206FR-071M21L (YAGEO) provides electrical and thermal equivalence to the RC3216F1214CS with identical temperature coefficient performance. This part is suitable for general industrial applications where automotive qualification is not required. Higher inventory availability (9,403 units) supports supply chain continuity.

For Automotive Applications: CRCW12061M21FKEA (Vishay Dale) is the preferred selection for automotive designs requiring AEC-Q200 qualification. This part maintains the ±100ppm/°C temperature coefficient of the base part while meeting automotive reliability standards. Highest inventory level (29,755 units) ensures availability for production volumes.

For Automotive Applications with Extended Temperature Stability Tolerance: RMCF1206FG1M21 (Stackpole Electronics Inc) provides AEC-Q200 qualification with ±200ppm/°C temperature coefficient. This variant is acceptable where the increased temperature coefficient does not exceed circuit design tolerances. Cut Tape packaging supports automated assembly processes.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical operating temperature range (-55°C to 155°C). Selection should be based on application requirements (automotive versus industrial), packaging format preference (Tape & Reel versus Cut Tape), and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-071M21L replace RC3216F1214CS in any application? A: RC1206FR-071M21L is electrically and thermally equivalent to RC3216F1214CS. Both parts share identical resistance (1.21 MOhms), tolerance (±1%), power rating (0.25W), package (1206), and temperature coefficient (±100ppm/°C). Substitution is valid for non-automotive applications. Packaging format differs (Tape & Reel versus bulk), which may affect procurement and assembly processes.

Q: What is the difference between RMCF1206FG1M21 and CRCW12061M21FKEA? A: Both parts are AEC-Q200 automotive qualified and electrically equivalent in resistance, tolerance, and power rating. The primary difference is temperature coefficient: RMCF1206FG1M21 has ±200ppm/°C while CRCW12061M21FKEA has ±100ppm/°C. For applications requiring tighter temperature stability, CRCW12061M21FKEA is preferred. Packaging differs (Cut Tape versus Tape & Reel).

Q: Are all substitute parts ROHS3 compliant? A: Yes. RC1206FR-071M21L, RMCF1206FG1M21, and CRCW12061M21FKEA are all ROHS3 compliant, matching the base part RC3216F1214CS compliance status.

Q: What does MSL 1 rating mean for these resistors? A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake requirements. All four parts carry MSL 1 rating, eliminating moisture-related handling constraints during storage and assembly.

Q: Can I use an automotive-qualified part in a non-automotive application? A: Yes. RMCF1206FG1M21 and CRCW12061M21FKEA are automotive-qualified but can be used in non-automotive applications. Automotive qualification represents additional testing and reliability assurance, making these parts suitable for any application within their electrical and thermal specifications.

Q: How do physical dimensions affect substitution? A: All substitute parts use the 1206 (3216 Metric) package with minor dimensional variations within specification. Length ranges from 3.10mm to 3.20mm and height from 0.60mm to 0.70mm. These variations are within standard 1206 package tolerances and do not affect PCB footprint compatibility or assembly processes.

Q: Which part should I select for high-volume production? A: CRCW12061M21FKEA offers the highest inventory (29,755 units) and is available in Tape & Reel format optimized for automated assembly. For automotive applications, this part combines availability with AEC-Q200 qualification. For non-automotive high-volume production, RC1206FR-071M21L provides equivalent performance with 9,403 units in stock.
