Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F1821CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 1.82 kOhms
• Tolerance: ±1%
• Power Rating: 0.25W (1/4W)
• Package / Case: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical requirements. Variations in physical dimensions (length, width, height) within the 1206 package specification, supplier packaging formats (Tape & Reel vs. Cut Tape), and optional certifications (such as Automotive AEC-Q200) do not affect functional substitutability but may influence application suitability based on end-use requirements.

Parameter Comparison

Engineering Selection Recommendations

Active Status Parts (Recommended for New Designs):

• AC1206FR-071K82L (YAGEO) — Active status with Automotive AEC-Q200 certification
• CR1206-FX-1821ELF (Bourns Inc.) — Active status with moisture-resistant construction
• CRCW12061K82FKEA (Vishay Dale) — Active status with Automotive AEC-Q200 certification and highest inventory availability (23,973 pcs)
• RC1206FR-071K82L (YAGEO) — Active status with highest inventory availability (104,004 pcs)
• RMCF1206FT1K82 (Stackpole Electronics Inc) — Active status with Automotive AEC-Q200 certification

Limited Availability Parts:

• ERJ-8ENF1821V (Panasonic Electronic Components) — Marked "Not For New Designs"; suitable only for legacy system maintenance or replacement applications
• MCR18ERTF1821 (Rohm Semiconductor) — Discontinued at DiGi Electronics; limited inventory (3,990 pcs); suitable only for existing stock replacement

All substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), ensuring compatibility with standard PCB assembly and storage conditions. Selection between active alternatives should be based on supply chain availability, lead time requirements, and any application-specific certifications (such as Automotive AEC-Q200 for automotive applications).

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF1821V or MCR18ERTF1821 be used as direct replacements?

A: Both parts meet all electrical and mechanical specifications for direct functional replacement. However, ERJ-8ENF1821V carries "Not For New Designs" status, and MCR18ERTF1821 is discontinued at DiGi Electronics. These parts are suitable only for maintenance of existing systems or replacement of failed components in legacy applications where supply continuity is not a concern.

Q: What is the difference between parts with and without Automotive AEC-Q200 certification?

A: Automotive AEC-Q200 certification indicates qualification for automotive applications under specific reliability and testing standards. Parts without this certification (such as CR1206-FX-1821ELF and RC1206FR-071K82L) are suitable for general industrial and consumer applications. Selection depends on end-use requirements; automotive applications should specify AEC-Q200 certified alternatives.

Q: Are there physical dimension differences between substitute parts?

A: All parts conform to the 1206 (3216 Metric) package specification. Minor variations exist in seated height (ranging from 0.024" to 0.030") and length/width dimensions (within ±0.006" tolerance). These variations remain within standard 1206 package tolerances and do not affect PCB assembly compatibility or electrical performance.

Q: What packaging formats are available?

A: Substitute parts are supplied in either Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats. Tape & Reel packaging is standard for high-volume automated assembly. Cut Tape & Digi-Reel® packaging is suitable for lower-volume or manual assembly operations. Packaging format does not affect component electrical or mechanical specifications.

Q: Why should RC1206FR-071K82L be considered despite higher inventory?

A: RC1206FR-071K82L (YAGEO) offers the highest inventory availability (104,004 pcs) among all substitutes, ensuring supply continuity and potentially shorter lead times. This part maintains Active product status and full specification equivalence, making it a reliable choice for applications without automotive certification requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), ensuring compatibility with modern PCB assembly processes and environmental regulations across all markets.
