Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3216F2104CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 2.1 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package / Case: 1206 (3216 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Two substitute parts meet these criteria: RC1206FR-072M1L (YAGEO) and CRCW12062M10FKEA (Vishay Dale). Both maintain identical electrical specifications and package compatibility while differing in physical dimensions within acceptable tolerances and packaging format.

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-072M1L (YAGEO) is a direct electrical and mechanical equivalent to the RC3216F2104CS. Both parts share identical resistance, tolerance, power rating, temperature coefficient, and operating range. Physical dimensions vary minimally (length 3.10mm vs 3.20mm, height 0.65mm vs 0.66mm), remaining within standard 1206 package tolerances. Both maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status. This substitute is suitable for applications requiring standard moisture-resistant thick film performance.

CRCW12062M10FKEA (Vishay Dale) meets all electrical and mechanical requirements with identical core specifications. This part includes automotive AEC-Q200 qualification, providing additional reliability assurance for automotive-grade applications. Physical dimensions match the original part exactly (length 3.20mm, width 1.60mm) with slightly reduced height (0.60mm vs 0.66mm). ROHS3 compliance and MSL 1 rating are maintained. This substitute is appropriate for applications requiring automotive-grade reliability or where AEC-Q200 qualification is specified.

Both substitutes are active products with substantial inventory availability (9094 and 18627 pieces respectively), ensuring supply continuity.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-072M1L replace RC3216F2104CS in all applications?

A: Yes. Both parts share identical electrical specifications (2.1 MOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C), composition (thick film), and package class (1206). Physical dimensions vary within standard package tolerances. Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between RC1206FR-072M1L and CRCW12062M10FKEA?

A: Both parts are electrically and mechanically equivalent to the original. The primary distinction is that CRCW12062M10FKEA carries automotive AEC-Q200 qualification, making it suitable for automotive applications requiring this certification. Physical dimensions are identical to the original for CRCW12062M10FKEA, while RC1206FR-072M1L has a slightly shorter length (3.10mm vs 3.20mm).

Q: Are there packaging differences between these substitutes?

A: RC3216F2104CS is supplied in standard packaging. RC1206FR-072M1L is packaged in Tape & Reel (TR) format. CRCW12062M10FKEA is also packaged in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume SMD component distribution and is compatible with automated assembly equipment.

Q: Do all three parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. CRCW12062M10FKEA additionally qualifies to automotive AEC-Q200 standard.

Q: What is the temperature coefficient specification and why does it matter?

A: All three parts specify ±100ppm/°C temperature coefficient across the -55°C to 155°C operating range. This parameter defines resistance value drift with temperature changes and is critical for precision analog circuits, measurement equipment, and temperature-sensitive applications.

Q: Are dimensional variations between these parts significant?

A: Dimensional variations are minimal and within standard 1206 package tolerances. RC1206FR-072M1L length is 3.10mm (vs 3.20mm original), and CRCW12062M10FKEA height is 0.60mm (vs 0.66mm original). These variations do not affect PCB layout compatibility or assembly processes for standard 1206 footprints.

Q: Which substitute should be selected for automotive applications?

A: CRCW12062M10FKEA is specified for automotive applications due to AEC-Q200 qualification. This certification ensures compliance with automotive reliability and quality standards.
