RC3216F4640CS 464 Ohm 1% 1/4W 1206 Chip Resistor Equivalent & Substitute Parts

Part Overview

The RC3216F4640CS is a 464 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 moisture-resistant construction suitable for general industrial and commercial applications. Substitute parts are identified when original inventory becomes unavailable or when alternative sourcing is required for supply chain optimization, provided that electrical and mechanical parameters remain within acceptable tolerances for the application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F4640CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 464 Ohms (exact match required)
• Tolerance: ±1% (no deviation permitted)
• Power rating: 0.25W / 1/4W (no reduction allowed)
• Package: 1206 (3216 Metric) (physical compatibility requirement)
• Composition: Thick Film (technology consistency)
• Temperature coefficient: ±100ppm/°C (stability equivalence)
• Operating temperature range: -55°C to 155°C (environmental compatibility)
• RoHS3 compliance: Required for regulatory alignment
• MSL rating: 1 (Unlimited) or equivalent (handling compatibility)

All identified substitute parts meet these mandatory criteria. Variations in physical dimensions (length, width, height) within the 1206 package specification, packaging format (Tape & Reel vs. bulk), and additional certifications (such as AEC-Q200 automotive qualification) do not disqualify substitution but represent secondary differentiators for specific application contexts.

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-07464RL (YAGEO): This part is the primary direct substitute. It maintains Active product status, identical electrical specifications, and equivalent moisture-resistant construction. The YAGEO RC_L series offers superior inventory availability (95,400 units) and is packaged in Tape & Reel format suitable for automated assembly processes. Physical dimensions (3.10mm L x 1.60mm W) fall within 1206 package tolerance and present no compatibility issues.

CRCW1206464RFKEA (Vishay Dale): This substitute is qualified for automotive applications under AEC-Q200 standard. It maintains Active product status and all mandatory electrical parameters. The CRCW series is suitable for applications requiring automotive-grade reliability. Inventory availability is moderate (6,195 units). This part is appropriate when automotive qualification is a system requirement.

ERJ-8ENF4640V (Panasonic): This part carries "Not For New Designs" product status, indicating it is in end-of-life phase. While electrically and mechanically equivalent, it is not recommended for new product development or long-term production programs. The ERJ-8EN series is suitable only for legacy system maintenance or repair applications where existing designs already incorporate this component. Inventory is substantial (101,968 units), but procurement should be limited to replacement scenarios.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-07464RL replace RC3216F4640CS in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (464 Ohms), tolerance (±1%), power rating (0.25W), package (1206), and operating temperature range (-55°C to 155°C). The primary difference is packaging format (Tape & Reel vs. bulk) and manufacturer. No circuit redesign is required.

Q: What is the difference between the Samsung and YAGEO versions?

A: The RC3216F4640CS (Samsung) and RC1206FR-07464RL (YAGEO) are functionally identical in electrical performance and thermal characteristics. Both are Active products with moisture-resistant thick film construction. The YAGEO part offers higher inventory availability and Tape & Reel packaging, which may provide cost or logistics advantages in high-volume production.

Q: Why is ERJ-8ENF4640V marked "Not For New Designs"?

A: The ERJ-8ENF4640V carries end-of-life status, meaning Panasonic has discontinued active development and long-term supply commitment for this product line. While the part remains electrically and mechanically equivalent, it is not suitable for new product development due to uncertain future availability. This part should be used only for maintenance of existing systems already incorporating the ERJ-8EN series.

Q: Are the automotive-qualified parts (CRCW1206464RFKEA and ERJ-8ENF4640V) necessary for non-automotive applications?

A: No. The AEC-Q200 automotive qualification is an additional feature that exceeds the base electrical and mechanical requirements. For non-automotive applications, the standard moisture-resistant versions (RC3216F4640CS or RC1206FR-07464RL) are fully adequate. Automotive-qualified parts may be selected when system specifications explicitly require AEC-Q200 compliance or when sourcing from automotive supply chains.

Q: What are the physical dimension differences between substitute parts?

A: All parts conform to the 1206 (3216 Metric) package specification. Minor variations exist: RC3216F4640CS and CRCW1206464RFKEA measure 3.20mm L x 1.60mm W, while RC1206FR-07464RL measures 3.10mm L x 1.60mm W. Height variations range from 0.60mm to 0.70mm. These differences fall within standard 1206 package tolerance and do not affect PCB layout or assembly compatibility.

Q: Can these parts be used interchangeably in automated pick-and-place assembly?

A: Yes, with packaging format consideration. RC1206FR-07464RL, CRCW1206464RFKEA, and ERJ-8ENF4640V are supplied in Tape & Reel format, which is standard for automated assembly. The RC3216F4640CS (bulk packaging) requires manual handling or tape conversion. All parts are compatible with standard 1206 component feeders once properly formatted.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. These parts do not require special dry-pack storage, desiccant handling, or bake-out procedures before soldering. They can be stored and handled under standard industrial conditions, simplifying supply chain logistics compared to higher MSL-rated components.
