RCS3216F1911CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F1911CS is a 1.91 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film resistor features anti-sulfur and moisture-resistant properties, operating across -55°C to 155°C with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is currently in active production status with 774 pieces available in inventory.

Substitute parts are identified when equivalent electrical specifications and mechanical dimensions are maintained across manufacturers, ensuring direct functional replacement in circuit applications without design modification.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Equivalence Requirements:

• Resistance value: 1.91 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.25W / 1/4W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match)

Mechanical Equivalence Requirements:

• Package type: 1206 (3216 Metric) (exact match)
• Composition: Thick Film (exact match)
• Number of terminations: 2 (exact match)

Compliance Requirements:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (minimum requirement)

All three identified substitute parts meet these criteria. Variations in packaging format (Tape & Reel vs. Cut Tape), manufacturer-specific features (Automotive AEC-Q200 certification), and minor dimensional tolerances do not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): CRCW12061K91FKEA (Vishay Dale) and RC1206FR-071K91L (YAGEO) are both in active production status and represent optimal substitutes for new designs. Both maintain full electrical and mechanical equivalence to the RCS3216F1911CS. CRCW12061K91FKEA includes Automotive AEC-Q200 certification, suitable for applications requiring automotive-grade reliability. RC1206FR-071K91L is available in Cut Tape and Digi-Reel packaging formats.

Secondary Selection (Legacy Applications): ERJ-8ENF1911V (Panasonic) meets all electrical and mechanical substitution criteria and carries Automotive AEC-Q200 certification. However, this part is designated "Not For New Designs" and should be reserved for legacy system maintenance or replacement applications only.

Compliance Consideration: All substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring compatibility with modern manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can CRCW12061K91FKEA directly replace RCS3216F1911CS in existing designs? A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (1.91 kOhms ±1%), power rating (0.25W), package (1206), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). The primary difference is packaging format (Tape & Reel vs. standard packaging) and manufacturer-specific features (Automotive AEC-Q200 certification on Vishay part).

Q: What is the difference between the Samsung RCS3216F1911CS and YAGEO RC1206FR-071K91L? A: Both parts are functionally equivalent. The YAGEO part is available in Cut Tape and Digi-Reel packaging. Minor dimensional variations exist: YAGEO length is 3.10mm versus Samsung's 3.20mm, and seated height is 0.65mm versus 0.66mm. These variations remain within standard 1206 package tolerances and do not affect circuit performance.

Q: Why is ERJ-8ENF1911V marked "Not For New Designs"? A: The Panasonic ERJ-8ENF1911V meets all electrical and mechanical specifications for substitution but carries a "Not For New Designs" status from the manufacturer. This designation indicates the part is in mature/legacy phase. It remains suitable for replacement in existing applications but should not be selected for new circuit designs where active-status alternatives are available.

Q: Are there packaging differences between substitute parts? A: Yes. RCS3216F1911CS uses standard packaging, CRCW12061K91FKEA is supplied in Tape & Reel (TR) format, ERJ-8ENF1911V is supplied in Tape & Reel (TR) format, and RC1206FR-071K91L is available in Cut Tape (CT) and Digi-Reel format. Packaging format does not affect electrical performance but may impact procurement, storage, and assembly processes.

Q: Do all substitute parts have the same moisture sensitivity level? A: Yes. All parts, including the main part RCS3216F1911CS and all three substitutes, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Can these parts be used interchangeably in automotive applications? A: CRCW12061K91FKEA and ERJ-8ENF1911V both carry Automotive AEC-Q200 certification, making them suitable for automotive-grade applications. RCS3216F1911CS and RC1206FR-071K91L do not carry explicit automotive certification but meet the same electrical and thermal specifications. Application requirements should determine whether AEC-Q200 certification is mandatory.
