Mandatory Matching Parameters:

• Resistance value: 1.43 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package type: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant
• Termination count: 2

Acceptable Variations:

• Manufacturer identity (different suppliers)
• Packaging format (Tape & Reel, Cut Tape, Digi-Reel)
• Physical dimensions within tolerance (length 0.122" to 0.126", width 0.063", height 0.024" to 0.028")
• Product status (Active or Not For New Designs)
• Additional certifications (AEC-Q200 automotive qualification)
• Feature enhancements (anti-sulfur, moisture resistant properties)

All identified substitute parts meet these criteria and are electrically and mechanically interchangeable with the main part.

• RC1206FR-071K43L (YAGEO): Active product status with moisture-resistant properties matching the main part. Inventory: 10892 Pcs.
• CRCW12061K43FKEA (Vishay Dale): Active product status with AEC-Q200 automotive qualification. Highest inventory availability at 26953 Pcs.

Secondary Selection (Legacy Applications):

• ERJ-8ENF1431V (Panasonic): Marked as "Not For New Designs" but remains in production with AEC-Q200 qualification. Suitable only for replacement or maintenance of existing assemblies. Inventory: 34378 Pcs.

Selection Criteria:

• For new designs: Select from AC1206FR-071K43L, RC1206FR-071K43L, or CRCW12061K43FKEA (all Active status).
• For automotive applications: AC1206FR-071K43L, CRCW12061K43FKEA, or ERJ-8ENF1431V (all AEC-Q200 qualified).
• For high-volume procurement: CRCW12061K43FKEA offers maximum inventory availability.
• For legacy system maintenance: ERJ-8ENF1431V maintains compatibility despite "Not For New Designs" status.

All substitute parts maintain identical electrical performance and mechanical compatibility with the RCS3216F1431CS.

Frequently Asked Questions (FAQ)

Q1: Can I use AC1206FR-071K43L as a direct replacement for RCS3216F1431CS?

A: Yes. Both parts share identical electrical specifications (1.43 kOhms ±1%, 0.25W), operate across the same temperature range (-55°C to 155°C), and use the same 1206 package. The AC1206FR-071K43L includes AEC-Q200 automotive qualification, which provides additional reliability assurance. Physical dimensions are within acceptable tolerance (3.10mm vs 3.20mm length).

Q2: What is the difference between the substitute parts?

A: All substitute parts meet the core electrical and mechanical requirements. Differences include: (1) Manufacturer identity (YAGEO, Vishay Dale, Panasonic); (2) Packaging format (Tape & Reel or Cut Tape); (3) Product status (Active vs Not For New Designs); (4) Automotive certification (AEC-Q200 present in AC1206FR-071K43L, CRCW12061K43FKEA, ERJ-8ENF1431V); (5) Inventory availability. All are ROHS3 compliant with MSL 1 rating.

Q3: Why is ERJ-8ENF1431V marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) has discontinued this part for new product development. However, it remains available for existing design maintenance and replacement applications. The part maintains full electrical and mechanical compatibility with the RCS3216F1431CS and retains AEC-Q200 qualification.

Q4: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within acceptable tolerance: Length ranges from 3.10mm to 3.20mm; Height ranges from 0.60mm to 0.70mm. Width is consistent at 1.60mm across all parts. These variations do not affect electrical performance or PCB assembly compatibility in standard 1206 footprints.

Q5: Which substitute part should I select for automotive applications?

A: AC1206FR-071K43L, CRCW12061K43FKEA, and ERJ-8ENF1431V all carry AEC-Q200 automotive qualification. CRCW12061K43FKEA is recommended for new automotive designs due to Active product status and highest inventory availability. AC1206FR-071K43L is an alternative with equivalent automotive credentials.

Q6: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This applies to all listed parts, including the main RCS3216F1431CS and all substitutes.

Q7: Can I mix different substitute parts in the same assembly?

A: Yes. All substitute parts are electrically and mechanically equivalent. Mixing different manufacturers or packaging formats in the same assembly does not affect circuit performance. However, for manufacturing consistency and traceability, using a single part number per assembly is recommended.

Q8: Is ROHS3 compliance important for my application?

A: ROHS3 compliance is mandatory for products sold in the European Union and many other regions. All listed parts, including RCS3216F1431CS and all substitutes, are ROHS3 compliant. Verify your application's regulatory requirements before final part selection.
