Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F68R1CS are qualified based on the following criteria:

Electrical Parameters (Critical):

• Resistance value: 68.1 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Critical):

• Package type: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance Parameters:

• RoHS status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH status: REACH Unaffected

All identified substitute parts maintain identical electrical and mechanical specifications. Variations in packaging format (Tape & Reel vs. Cut Tape) and minor height differences (0.50mm to 0.70mm) do not affect functional equivalence. Automotive-rated variants (AEC-Q200) provide additional qualification for automotive applications.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: RC2012F68R1CS (Samsung Electro-Mechanics) or RC0805FR-0768R1L (YAGEO) are suitable direct replacements. Both maintain ROHS3 compliance, moisture resistance, and identical electrical specifications. RC2012F68R1CS is available in Cut Tape packaging for lower-volume requirements.

For Automotive Applications: CRCW080568R1FKEA (Vishay Dale), ERJ-6ENF68R1V (Panasonic), or RMCF0805FT68R1 (Stackpole Electronics Inc) are qualified alternatives. All three carry AEC-Q200 automotive qualification and ROHS3 compliance. CRCW080568R1FKEA and RMCF0805FT68R1 offer the lowest profile heights (0.50mm and 0.65mm respectively).

Compliance Considerations: CRCW080568R1FKTA (Vishay Dale) is not recommended for new designs due to RoHS non-compliance and REACH-affected status, despite matching electrical and mechanical specifications.

Packaging Format: All substitute parts are available in Tape & Reel format except RC2012F68R1CS, which is available in Cut Tape. Selection depends on assembly process requirements and volume specifications.

Frequently Asked Questions (FAQ)

Q: Can RC2012F68R1CS be directly replaced with CRCW080568R1FKEA? A: Yes. Both parts share identical electrical specifications (68.1 Ω ±1%, 0.125W), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and 0805 package dimensions. The primary difference is CRCW080568R1FKEA includes automotive AEC-Q200 qualification and has a lower profile height (0.50mm vs. 0.66mm). This lower height may require PCB layout verification for clearance-critical applications.

Q: What is the difference between RC2012F68R1CS and RCS2012F68R1CS? A: RCS2012F68R1CS includes anti-sulfur properties in addition to moisture resistance and is supplied in Tape & Reel format. RC2012F68R1CS omits the anti-sulfur feature and is available in Cut Tape format. Both are Samsung Electro-Mechanics products with identical electrical performance and ROHS3 compliance.

Q: Are automotive-rated parts (AEC-Q200) compatible with non-automotive applications? A: Yes. Automotive-qualified parts (CRCW080568R1FKEA, ERJ-6ENF68R1V, RMCF0805FT68R1) exceed standard industrial requirements and are fully compatible with non-automotive circuits. AEC-Q200 qualification indicates additional reliability testing and process controls.

Q: Does the height difference between substitute parts affect PCB assembly? A: Height variations range from 0.50mm to 0.70mm. For standard PCB designs with typical solder reflow profiles and component placement tolerances, these differences are within acceptable limits. Height-critical applications (such as those with low clearance requirements) should verify specific part heights against PCB design constraints.

Q: Why is CRCW080568R1FKTA not recommended? A: CRCW080568R1FKTA is RoHS non-compliant and REACH-affected, making it unsuitable for applications requiring regulatory compliance. CRCW080568R1FKEA is the compliant equivalent from the same manufacturer.

Q: Can these 0805 resistors be used interchangeably in high-frequency circuits? A: All listed parts are thick film 0805 resistors with identical electrical specifications and temperature coefficients. Frequency performance is determined by parasitic inductance and capacitance inherent to the 0805 package format. No frequency-dependent differences exist between the listed substitutes.

Q: What packaging format should be selected for automated assembly? A: Tape & Reel format is standard for automated pick-and-place assembly. All substitute parts except RC2012F68R1CS are available in Tape & Reel. RC2012F68R1CS in Cut Tape format is suitable for manual assembly or lower-volume production runs.
