Key Parameters

Substitute Part Grouping Explanation

Substitute parts for RC2012F3403CS are qualified based on the following criteria:

Electrical Parameters (Critical):

• Resistance value: 340 kOhms
• 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:

• RoHS3 compliance
• Moisture Sensitivity Level 1
• REACH Unaffected status

All identified substitute parts match these core parameters. Variations in seated height and packaging format (Tape & Reel vs. Cut Tape) do not affect electrical or functional compatibility.

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to RC2012F3403CS based on matching electrical and mechanical specifications. Selection between alternatives depends on application requirements and supply chain considerations:

RC0805FR-07340KL (YAGEO): Direct electrical and mechanical equivalent with moisture resistant composition. Packaged in Cut Tape & Digi-Reel format. Suitable for general industrial applications requiring standard thick film performance.

CRCW0805340KFKEA (Vishay Dale): Includes AEC-Q200 automotive qualification rating. Packaged in Tape & Reel format. Recommended for automotive and high-reliability applications where automotive-grade certification is specified.

ERJ-6ENF3403V (Panasonic): Includes AEC-Q200 automotive qualification rating. Packaged in Tape & Reel format. Recommended for automotive and high-reliability applications where automotive-grade certification is specified.

All parts maintain ROHS3 compliance, MSL Level 1 rating, and identical electrical performance within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07340KL replace RC2012F3403CS in any application?

A: Yes. RC0805FR-07340KL matches all critical electrical parameters (340 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C) and mechanical specifications (0805 package, 2.00mm x 1.25mm). The seated height difference (0.024" vs. 0.026") is within standard PCB design tolerances and does not affect functionality.

Q: What is the difference between the Samsung part and the Vishay/Panasonic parts?

A: The primary difference is automotive qualification. CRCW0805340KFKEA and ERJ-6ENF3403V carry AEC-Q200 ratings, making them suitable for automotive applications. RC2012F3403CS and RC0805FR-07340KL are standard industrial-grade components. All four parts are electrically and mechanically identical.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect compatibility?

A: No. Packaging format affects handling and assembly logistics only. Electrical and mechanical performance are identical regardless of packaging. RC0805FR-07340KL (Cut Tape & Digi-Reel) and the other parts (Tape & Reel) are functionally interchangeable.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RC2012F3403CS, RC0805FR-07340KL, CRCW0805340KFKEA, and ERJ-6ENF3403V are all ROHS3 compliant with MSL Level 1 rating and REACH Unaffected status.

Q: Can I use CRCW0805340KFKEA in a non-automotive application?

A: Yes. AEC-Q200 qualification is a superset of standard industrial specifications. CRCW0805340KFKEA meets or exceeds all requirements for standard industrial applications and can be used as a direct substitute in any application where RC2012F3403CS is specified.

Q: What determines if a part is a valid substitute?

A: Valid substitutes must match: resistance value (340 kOhms), tolerance (±1%), power rating (0.125W), package type (0805), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL 1).
