RCS3216F1874CS Equivalent & Substitute Parts

Part Overview

The RCS3216F1874CS is a 1.87 MOhms ±1% 0.25W chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This thick film resistor features anti-sulfur and moisture-resistant properties, operating across the temperature range of -55°C to 155°C. The part is currently active in production with 778 pieces in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements necessitate alternative manufacturer specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F1874CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 1.87 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these mandatory parameters. Variations in physical dimensions (length, width, height) and specific feature sets (anti-sulfur vs. automotive AEC-Q200 qualification) do not disqualify substitution but represent secondary differentiators for application-specific requirements.

Parameter Comparison

Engineering Selection Recommendations

CRCW12061M87FKEA (Vishay Dale) is suitable for applications requiring automotive-grade qualification. This part carries AEC-Q200 certification, indicating compliance with automotive reliability standards. The slightly lower maximum seated height (0.024" vs. 0.026") may provide advantages in space-constrained PCB layouts. All electrical and environmental parameters are equivalent to the primary part.

RC1206FR-071M87L (YAGEO) provides a direct functional equivalent with moisture-resistant properties matching the primary part's environmental protection. The length dimension is 0.004" shorter (3.10mm vs. 3.20mm), which may be relevant for tight mechanical tolerances. This part is suitable for general industrial and consumer applications requiring equivalent performance specifications.

Both substitute parts maintain active production status and full RoHS3 compliance, ensuring long-term availability and regulatory conformance.

Frequently Asked Questions (FAQ)

Q: Can CRCW12061M87FKEA replace RCS3216F1874CS in any application?

A: Yes, provided the application does not specifically exclude automotive-qualified components. The CRCW12061M87FKEA meets all electrical and environmental parameters of the RCS3216F1874CS. The AEC-Q200 qualification is an additional feature that does not prevent use in non-automotive applications.

Q: What is the significance of the dimension differences between RC1206FR-071M87L and RCS3216F1874CS?

A: The RC1206FR-071M87L has a length of 3.10mm compared to the RCS3216F1874CS at 3.20mm, a difference of 0.10mm. This variation is within typical manufacturing tolerances for 1206 package resistors and does not affect electrical performance. Verify PCB layout constraints if space margins are critical.

Q: Are all three parts suitable for the full -55°C to 155°C temperature range?

A: Yes. All three parts specify identical operating temperature ranges of -55°C to 155°C and identical temperature coefficients of ±100ppm/°C.

Q: What packaging formats are available for these parts?

A: The RCS3216F1874CS is supplied in standard packaging. Both CRCW12061M87FKEA and RC1206FR-071M87L are available in Tape & Reel (TR) format, which is standard for high-volume SMD assembly operations.

Q: Do all parts meet RoHS requirements?

A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: Which part should be selected for moisture-sensitive applications?

A: All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. The RCS3216F1874CS and RC1206FR-071M87L both explicitly feature moisture-resistant properties.
