RC3216F8450CS 845 Ohm 1% 1/4W 1206 Chip Resistor Equivalent & Substitute Parts

Part Overview

The RC3216F8450CS is a 845 Ohm ±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 813 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 are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design flexibility across multiple qualified suppliers is needed while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F8450CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 845 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All substitute parts listed meet these mandatory parameters. Variations in physical dimensions (length, width, height) within standard tolerances and differences in packaging format (Tape & Reel vs. other formats) do not affect functional substitutability. Product status and specific feature enhancements (such as automotive AEC-Q200 qualification) are noted for selection context but do not disqualify substitution.

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-07845RL (YAGEO): This part maintains Active product status with the highest inventory availability among YAGEO offerings. All electrical and mechanical parameters are equivalent to the RC3216F8450CS. Selection is appropriate for applications requiring continuous supply assurance and manufacturer support.

CRCW1206845RFKEA (Vishay Dale): This part includes automotive AEC-Q200 qualification in addition to standard ROHS3 compliance. Active product status and substantial inventory levels support long-term availability. Selection is appropriate for automotive applications or designs requiring enhanced reliability qualification.

ERJ-8ENF8450V (Panasonic Electronic Components): This part carries "Not For New Designs" product status, indicating the manufacturer is transitioning away from this component. While electrically and mechanically equivalent, this part should be selected only when existing inventory must be consumed or when design refresh is not feasible. New designs should prioritize RC1206FR-07845RL or CRCW1206845RFKEA.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-07845RL be used as a direct replacement for RC3216F8450CS?

A: Yes. Both parts share identical resistance (845 Ohms), tolerance (±1%), power rating (0.25W), package (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL 1). Physical dimension variations (length 3.10mm vs. 3.20mm, height 0.65mm vs. 0.66mm) fall within standard manufacturing tolerances and do not affect functional performance or PCB layout compatibility.

Q: What is the difference between CRCW1206845RFKEA and the other substitutes?

A: CRCW1206845RFKEA includes automotive AEC-Q200 qualification, which certifies the component for automotive-grade reliability and environmental stress testing. This qualification is an enhancement beyond the base electrical specifications and does not prevent use in non-automotive applications. All other electrical and mechanical parameters remain identical to RC3216F8450CS.

Q: Why is ERJ-8ENF8450V marked "Not For New Designs"?

A: "Not For New Designs" indicates that Panasonic Electronic Components is discontinuing this product line. While the part remains functionally equivalent and is currently in stock, designs incorporating this component will face future supply constraints. For new product development, RC1206FR-07845RL or CRCW1206845RFKEA are recommended to ensure long-term component availability.

Q: Are there packaging format differences between these substitutes?

A: All listed substitutes are supplied in Tape & Reel (TR) format. The RC3216F8450CS packaging format is not specified in the provided data. Tape & Reel packaging is standard for high-volume SMD assembly and is compatible with automated pick-and-place equipment. Confirm packaging requirements with your assembly partner if non-standard formats are required.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes, for PCB designs already qualified with RC3216F8450CS. All substitute parts share the 1206 (3216 Metric) package footprint. Physical dimension variations (maximum 0.1mm in length, 0.05mm in height) are within standard PCB design tolerances and do not require layout modifications. Electrical performance remains identical across all listed substitutes.
