Key Parameters

Substitute Part Grouping Explanation

Substitute parts for RC2012F3400CS are qualified based on strict equivalence of the following parameters:

Electrical Equivalence Criteria:

• Resistance value: 340 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Equivalence Criteria:

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

Compliance & Environmental Criteria:

• RoHS3 compliance
• MSL Level 1 (Unlimited)
• REACH Unaffected status
• Tape & Reel packaging format

All substitute parts listed maintain these core parameters. Variations in seated height (ranging from 0.020" to 0.028") remain within acceptable PCB assembly tolerances and do not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (RC0805FR-07340RL - YAGEO): RC0805FR-07340RL from YAGEO is a direct functional equivalent with identical electrical specifications and RoHS3 compliance. This part maintains all core parameters with seated height of 0.024" (0.60mm), which is within standard PCB assembly tolerances. Product status is Active with high inventory availability (21,268 pcs).

Automotive-Qualified Alternatives: CRCW0805340RFKEA (Vishay Dale), ERJ-6ENF3400V (Panasonic), and RMCF0805FT340R (Stackpole) are qualified substitutes with AEC-Q200 automotive certification. These parts maintain identical electrical and mechanical specifications with RoHS3 compliance. Selection among these three depends on supply chain availability and specific application requirements for automotive-grade components. Seated heights range from 0.020" to 0.028", all within acceptable assembly specifications.

Compliance Verification: All substitute parts maintain REACH Unaffected status, ROHS3 compliance, and MSL Level 1 rating. No additional qualification testing is required for direct substitution based on provided compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07340RL replace RC2012F3400CS in existing designs? A: Yes. RC0805FR-07340RL is a direct substitute with identical resistance (340 Ohms), tolerance (±1%), power rating (0.125W), package (0805), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Both components are RoHS3 compliant with MSL Level 1 rating.

Q: What is the difference between the Samsung part and automotive-qualified alternatives? A: The Samsung RC2012F3400CS is specified as moisture-resistant thick film. The automotive alternatives (CRCW0805340RFKEA, ERJ-6ENF3400V, RMCF0805FT340R) carry AEC-Q200 certification. All maintain identical electrical specifications and operating parameters. Selection depends on application requirements for automotive qualification.

Q: Are there dimensional compatibility concerns with different seated heights? A: Seated heights range from 0.020" (CRCW0805340RFKEA) to 0.028" (ERJ-6ENF3400V). These variations fall within standard PCB assembly tolerances for 0805 package components and do not affect functional substitution or reflow soldering processes.

Q: Do all substitute parts have the same moisture sensitivity level? A: Yes. All listed substitute parts maintain MSL Level 1 (Unlimited) rating, identical to the original RC2012F3400CS. No additional moisture handling precautions are required when switching between these parts.

Q: Which substitute part has the highest inventory availability? A: ERJ-6ENF3400V (Panasonic) has the highest inventory with 54,595 pcs in stock, followed by RC0805FR-07340RL (YAGEO) with 21,268 pcs and CRCW0805340RFKEA (Vishay Dale) with 13,628 pcs.

Q: Are all substitute parts suitable for the same temperature range applications? A: Yes. All substitute parts operate across the identical temperature range of -55°C ~ 155°C with ±100ppm/°C temperature coefficient, matching the original RC2012F3400CS specifications.
