Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F1433CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance value: 143 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match Exactly):

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

Compliance Parameters (Must Match or Exceed):

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

All substitute parts listed below satisfy these requirements. Variations in physical dimensions (length, width, height) within standard manufacturing tolerances do not affect substitutability, as long as the package designation remains 1206 (3216 Metric).

Engineering Selection Recommendations

Primary Selection: RCS3216F1433CS (Samsung Electro-Mechanics)

The RCS3216F1433CS remains the recommended choice for new designs. This part maintains active production status, ensuring long-term availability and supply chain stability. The anti-sulfur and moisture-resistant thick film construction provides enhanced environmental protection. Current inventory of 952 pieces supports immediate procurement requirements.

Secondary Selection: RC1206FR-07143KL (YAGEO)

The RC1206FR-07143KL serves as the preferred substitute when RCS3216F1433CS availability is constrained. This part maintains active product status with substantial inventory (30072 pieces), ensuring reliable supply. The moisture-resistant thick film composition matches the primary part's environmental specifications. Tape & Reel packaging accommodates high-volume manufacturing processes.

Tertiary Selection: ERJ-8ENF1433V (Panasonic Electronic Components)

The ERJ-8ENF1433V is electrically and mechanically equivalent but carries "Not For New Designs" status. This designation indicates Panasonic has discontinued active development for this part number. While the part meets all electrical and compliance requirements, selection should be limited to legacy system maintenance or applications where existing design validation has already been completed. The automotive AEC-Q200 qualification provides additional assurance for demanding environments, though this certification exceeds the base requirements of the primary part.

Selection Criteria Summary:

• New Designs: RCS3216F1433CS or RC1206FR-07143KL
• Legacy System Support: Any of the three parts
• High-Volume Production: RC1206FR-07143KL (largest inventory)
• Automotive Applications: ERJ-8ENF1433V (AEC-Q200 qualified)

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF1433V be used as a direct replacement for RCS3216F1433CS?

A: Yes, from an electrical and mechanical standpoint. The ERJ-8ENF1433V meets all core specifications: 143 kOhms ±1%, 0.25W power rating, 1206 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. However, the "Not For New Designs" status indicates Panasonic has discontinued active support. Use this part only for legacy system maintenance or when existing design validation is already complete.

Q: What is the difference between the physical dimensions listed for each part?

A: Minor dimensional variations exist within standard manufacturing tolerances. RCS3216F1433CS measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with 0.026" max height. RC1206FR-07143KL measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with 0.026" max height. ERJ-8ENF1433V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with 0.028" max height. These variations do not affect PCB layout compatibility or functional performance, as all parts conform to the 1206 (3216 Metric) package standard.

Q: Does packaging format (bulk vs. Tape & Reel) affect electrical performance?

A: No. Packaging format affects only handling, storage, and manufacturing process integration. RCS3216F1433CS is supplied in bulk format, while RC1206FR-07143KL and ERJ-8ENF1433V are supplied in Tape & Reel format. The electrical and mechanical properties remain identical regardless of packaging configuration.

Q: Are all three parts ROHS3 compliant?

A: Yes. RCS3216F1433CS, ERJ-8ENF1433V, and RC1206FR-07143KL all carry ROHS3 compliance certification. All three parts also maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Which part should be selected for automotive applications?

A: ERJ-8ENF1433V carries AEC-Q200 automotive qualification, providing additional assurance for demanding automotive environments. However, this certification is not a requirement for the base application. If automotive qualification is mandated by design specifications, ERJ-8ENF1433V is the appropriate selection despite its "Not For New Designs" status. For non-automotive applications, RCS3216F1433CS or RC1206FR-07143KL are preferred.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All three parts are mechanically and electrically equivalent within the specified parameters. PCB layout, solder pad dimensions, and assembly processes remain unchanged. No design modifications are required when substituting between these parts.

Q: What is the significance of the ±100ppm/°C temperature coefficient?

A: The ±100ppm/°C temperature coefficient defines the maximum resistance change per degree Celsius across the -55°C to 155°C operating range. All three substitute parts maintain this identical specification, ensuring equivalent thermal stability and predictable performance across the full temperature range.
