RC3216F1433CS Equivalent & Substitute Parts Reference

Part Overview

The RC3216F1433CS is a 143 kOhms ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This component is classified as Active product status with 927 pieces currently in stock. The part is designed for general-purpose applications requiring moisture-resistant thick film construction with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts become necessary when the primary manufacturer part experiences supply constraints, extended lead times, or when design requirements mandate specific certifications such as automotive AEC-Q200 qualification or alternative packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F1433CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 143 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
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant
• Number of terminations: 2

All identified substitute parts meet these mandatory parameters. Variations in product status, manufacturer certifications (such as AEC-Q200), and physical dimensions within tolerance ranges do not disqualify substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-07143KL (YAGEO) is the primary substitute option. This part maintains Active product status identical to the main part, carries moisture-resistant features matching the RC3216F1433CS specification, and demonstrates equivalent physical dimensions (0.026" seated height). YAGEO inventory of 30,072 pieces provides reliable supply availability.

RMCF1206FT143K (Stackpole Electronics Inc) serves as a secondary substitute for applications requiring automotive AEC-Q200 certification. This part is Active status and maintains all electrical parameters. The seated height of 0.028" represents a 0.002" (0.05mm) increase, which remains within typical PCB design tolerances for 1206 package applications.

ERJ-8ENF1433V (Panasonic Electronic Components) is classified as Not For New Designs and should be selected only when existing inventory or legacy system requirements mandate Panasonic sourcing. This part carries automotive AEC-Q200 certification and maintains all electrical equivalence parameters. Panasonic inventory of 76,589 pieces indicates strong availability despite the discontinued status for new designs.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-07143KL replace RC3216F1433CS in all applications?

A: Yes. Both parts share identical electrical specifications (143 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C), package type (1206 / 3216 Metric), composition (thick film), and compliance ratings (ROHS3, MSL 1). Physical dimension variance (0.122" vs 0.126" length) falls within standard 1206 package tolerances and does not affect PCB footprint compatibility.

Q: What is the difference between moisture-resistant and AEC-Q200 variants?

A: Moisture-resistant designation indicates the part meets general moisture protection standards. AEC-Q200 certification indicates the part meets automotive-grade reliability and qualification standards established by the Automotive Electronics Council. Both feature sets are compatible with the RC3216F1433CS electrical specifications. Selection depends on application requirements, not electrical equivalence.

Q: Why is ERJ-8ENF1433V marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) has discontinued this part for new design applications. However, the part remains electrically and mechanically equivalent to RC3216F1433CS. Use this part only when legacy system support or existing inventory constraints require it.

Q: Are there physical dimension differences that affect PCB layout?

A: Seated height varies between 0.026" (RC3216F1433CS, RC1206FR-07143KL) and 0.028" (ERJ-8ENF1433V, RMCF1206FT143K). This 0.002" difference is within standard 1206 package tolerance and does not require PCB redesign. Length dimensions (0.122" to 0.126") also remain within 1206 specification ranges.

Q: Which substitute offers the best supply availability?

A: ERJ-8ENF1433V (Panasonic) shows the highest inventory at 76,589 pieces. RC1206FR-07143KL (YAGEO) provides 30,072 pieces with Active product status. RMCF1206FT143K (Stackpole) maintains 10,503 pieces. Selection should prioritize Active status parts (YAGEO, Stackpole) for new designs unless supply constraints mandate otherwise.

Q: Can these parts be used interchangeably in automotive applications?

A: RMCF1206FT143K and ERJ-8ENF1433V carry AEC-Q200 certification for automotive use. RC3216F1433CS and RC1206FR-07143KL do not carry this certification. For automotive applications requiring AEC-Q200 qualification, select RMCF1206FT143K (Active status) or ERJ-8ENF1433V (legacy status).
