RCS3216F2102CS Equivalent & Substitute Parts

Part Overview

The RCS3216F2102CS is a 21 kOhms ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This component features anti-sulfur and moisture-resistant construction with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is currently in active production status with 708 pieces available in stock.

Substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating, temperature coefficient, operating temperature range) and mechanical compatibility (package type, physical dimensions, termination count). All substitute candidates maintain identical or equivalent performance parameters within the allowed tolerances for this resistor category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F2102CS are qualified based on the following criteria:

Electrical Parameter Matching:

• Resistance value: 21 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameter Matching:

• Package type: 1206 (3216 Metric) (exact match required)
• Number of terminations: 2 (exact match required)
• Physical dimensions: Compatible within standard 1206 tolerances

Compliance Matching:

• RoHS3 compliance (all candidates meet this requirement)
• Moisture sensitivity level: MSL 1 (all candidates meet this requirement)

All three substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the main part in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): CRCW120621K0FKEA (Vishay Dale) and RC1206FR-0721KL (YAGEO) are both in active production status and represent the preferred choices for new designs. Both parts maintain full electrical and mechanical compatibility with the RCS3216F2102CS.

CRCW120621K0FKEA includes automotive AEC-Q200 qualification, which provides additional reliability assurance for applications requiring automotive-grade components. This part is available in high inventory (17,401 pieces).

RC1206FR-0721KL offers moisture-resistant construction similar to the main part and maintains active product status. This part is available in substantial inventory (24,637 pieces).

Secondary Selection (Legacy Status): ERJ-8ENF2102V (Panasonic) is marked as "Not For New Designs" and should be used only for replacement or repair of existing assemblies. This part carries automotive AEC-Q200 qualification and has the highest inventory availability (39,738 pieces), making it suitable for field service applications where the original part is unavailable.

Compliance Considerations: All four parts (main part and three substitutes) are ROHS3 compliant and carry MSL 1 (unlimited) moisture sensitivity rating, ensuring compatibility in standard manufacturing and storage environments without special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can CRCW120621K0FKEA be used as a direct replacement for RCS3216F2102CS?

A: Yes. Both parts share identical electrical specifications (21 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C operating range) and mechanical compatibility (1206 package, 2 terminations). The maximum seated height difference (0.024" vs 0.026") is within standard PCB assembly tolerances. CRCW120621K0FKEA is in active production status.

Q: What is the difference between the Samsung RCS3216F2102CS and YAGEO RC1206FR-0721KL?

A: Both parts are electrically identical (21 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C). The primary differences are manufacturer and packaging format. Samsung RCS3216F2102CS features anti-sulfur and moisture-resistant construction. YAGEO RC1206FR-0721KL features moisture-resistant construction. Physical dimensions vary slightly (length 0.126" vs 0.122"), but both fit standard 1206 footprints. Both are in active production.

Q: Why is ERJ-8ENF2102V marked "Not For New Designs"?

A: The ERJ-8ENF2102V is classified as "Not For New Designs" by Panasonic, indicating the manufacturer is transitioning this product line. However, the part remains electrically and mechanically compatible with RCS3216F2102CS and is suitable for replacement applications or field service where original parts are unavailable. For new product designs, CRCW120621K0FKEA or RC1206FR-0721KL are recommended.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RCS3216F2102CS, CRCW120621K0FKEA, ERJ-8ENF2102V, and RC1206FR-0721KL are all ROHS3 compliant. All parts carry MSL 1 (unlimited) moisture sensitivity level, requiring no special moisture control during storage or assembly.

Q: What is the significance of AEC-Q200 qualification on CRCW120621K0FKEA and ERJ-8ENF2102V?

A: AEC-Q200 is an automotive industry qualification standard. Parts carrying this rating have undergone additional reliability testing and are approved for automotive applications. This qualification is not present on the main part (RCS3216F2102CS) or RC1206FR-0721KL. For non-automotive applications, this qualification provides no functional advantage but indicates higher quality assurance standards.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, within standard manufacturing tolerances. All parts use the 1206 (3216 Metric) package with 2 terminations and fit identical PCB footprints. Maximum seated height variations (0.024" to 0.028") are within typical PCB assembly clearance specifications. No PCB redesign is required when substituting between these parts.
