RCS3216F7680CS Equivalent & Substitute Parts

Part Overview

The RCS3216F7680CS is a 768 Ohms ±1% 0.25W chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This thick film resistor features anti-sulfur and moisture-resistant properties, with an operating temperature range of -55°C to 155°C. The part is currently in active production status with 1130 pieces available in stock. Substitute parts are necessary to address supply chain flexibility, alternative sourcing options, and specific application requirements such as automotive qualification or design phase transitions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F7680CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 768 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 to 155°C
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All four substitute parts meet these mandatory parameters. Variations in physical dimensions (length, width, height) and specific feature sets (automotive AEC-Q200 qualification, anti-sulfur coating) do not disqualify substitution but indicate application-specific suitability. Product status differences are noted for design phase considerations.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Designs: AC1206FR-07768RL (YAGEO), CRCW1206768RFKEA (Vishay Dale), and RC1206FR-07768RL (YAGEO) are all suitable substitutes with active product status. These parts maintain full electrical and mechanical equivalence to the RCS3216F7680CS.

For Automotive Applications: AC1206FR-07768RL, CRCW1206768RFKEA, and ERJ-8ENF7680V all carry AEC-Q200 automotive qualification. If automotive-grade components are required, these three options provide the necessary certification.

For New Design Phases: ERJ-8ENF7680V carries a "Not For New Designs" status and should not be selected for new development projects. This part is suitable only for legacy system maintenance or existing design continuation.

For Anti-Sulfur Requirements: The RCS3216F7680CS specifically includes anti-sulfur coating. Among the substitutes, only the RCS3216F7680CS provides this feature. If anti-sulfur properties are mandatory, no direct substitute with this specification is available in the provided list.

For Supply Chain Optimization: RC1206FR-07768RL offers the highest inventory availability (131,802 pieces) and maintains active product status, making it the preferred choice for high-volume procurement.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-07768RL replace RCS3216F7680CS in existing designs? A: Yes. AC1206FR-07768RL meets all mandatory electrical and mechanical parameters. The primary difference is automotive AEC-Q200 qualification, which is an additional feature rather than a substitution barrier.

Q: What is the significance of "Not For New Designs" status on ERJ-8ENF7680V? A: This designation indicates the manufacturer is transitioning the part out of production. While electrically and mechanically equivalent, ERJ-8ENF7680V should not be used in new product development. It is suitable only for sustaining existing designs or legacy system support.

Q: Are there dimensional differences between these parts? A: Yes. Length varies between 0.122" (3.10mm) and 0.126" (3.20mm), and height ranges from 0.024" (0.60mm) to 0.028" (0.70mm). These variations are within typical PCB layout tolerances for 1206 package components and do not affect electrical performance or footprint compatibility.

Q: Which substitute offers the best inventory availability? A: RC1206FR-07768RL has 131,802 pieces in stock, significantly higher than other options. This makes it the optimal choice for high-volume production requirements.

Q: Does the absence of anti-sulfur coating on substitute parts affect performance? A: The RCS3216F7680CS includes anti-sulfur and moisture-resistant properties. Substitute parts specify moisture resistance but do not explicitly include anti-sulfur coating. If sulfur resistance is a critical application requirement, the RCS3216F7680CS should be retained as the primary component.

Q: Are all substitute parts REACH compliant? A: Yes. All substitute parts listed carry REACH Unaffected status, matching the RCS3216F7680CS compliance profile.

Q: Can ERJ-8ENF7680V be used in automotive applications? A: Yes. ERJ-8ENF7680V carries AEC-Q200 automotive qualification. However, its "Not For New Designs" status restricts its use to existing automotive designs or legacy system maintenance only.
