RC2012F1403CS 140kΩ ±1% 1/8W 0805 Chip Resistor Equivalent & Substitute Parts

Part Overview

The RC2012F1403CS is a thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 140 kOhms with ±1% tolerance and 0.125W (1/8W) power dissipation in 0805 (2012 Metric) package format. This component is classified as Active product status with moisture-resistant construction and ROHS3 compliance. Substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package size and form factor), and environmental operating parameters. Alternative sources become necessary for supply chain continuity, inventory availability, or application-specific certifications such as automotive AEC-Q200 qualification.

Electrical Parameters (Must Match Exactly):

Resistance: 140 kOhms
Tolerance: ±1%
Power Rating: 0.125W (1/8W)
Temperature Coefficient: ±100ppm/°C
Operating Temperature Range: -55°C to 155°C

Mechanical Parameters (Must Match Exactly):

Package / Case: 0805 (2012 Metric)
Number of Terminations: 2

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compatibility):

ERJ-6ENF1403V, KTR10EZPF1403, RC0805FR-07140KL, RMCF0805FT140K, and CRCW0805140KFKEA are all Active products with complete electrical and mechanical equivalence to RC2012F1403CS. Selection among these options is based on:

Supply availability: CRCW0805140KFKEA (19,460 pcs), ERJ-6ENF1403V (91,759 pcs), and RC0805FR-07140KL (1,800 pcs) offer higher inventory levels.
Packaging format: Tape & Reel (TR) format is standard for high-volume applications; Cut Tape (CT) & Digi-Reel® format (RC0805FR-07140KL) suits lower-volume or mixed-component orders.
Automotive qualification: ERJ-6ENF1403V, KTR10EZPF1403, RMCF0805FT140K, and CRCW0805140KFKEA carry AEC-Q200 certification for automotive-grade applications. KTR10EZPF1403 includes additional High Voltage rating.
Moisture resistance: RC2012F1403CS and RC0805FR-07140KL are explicitly rated for moisture resistance; other substitutes carry MSL 1 (Unlimited) classification.

Secondary Substitute (Discontinued Status):

MCR10ERTF1403 is discontinued at DiGi Electronics and should be used only when existing inventory is available and no Active alternative is accessible. This part maintains full electrical and mechanical compatibility but carries product lifecycle risk.

Height Considerations:

All substitutes fit within standard 0805 package height specifications. CRCW0805140KFKEA offers the lowest profile (0.50mm max), beneficial for space-constrained PCB layouts. Height variations (0.60mm to 0.70mm) are within standard tolerance and do not affect circuit performance or board assembly.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC2012F1403CS with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts match the critical electrical parameters (140 kΩ, ±1%, 0.125W) and mechanical specifications (0805 package, 2 terminations, thick film composition). No circuit redesign is required. Substitution is a direct component swap at the PCB assembly level.

Q: What is the difference between "Direct Manufacturer Part Number" and "Similar Manufacturer Part Number" designations?

A: Direct substitutes (ERJ-6ENF1403V, KTR10EZPF1403, RC0805FR-07140KL, RMCF0805FT140K) are functionally and mechanically identical to RC2012F1403CS with no performance trade-offs. Similar parts (CRCW0805140KFKEA, MCR10ERTF1403) also meet all electrical and mechanical requirements but may have minor physical variations (such as height profile) that do not affect circuit operation. Both categories are valid substitutes.

Q: Does Automotive AEC-Q200 certification affect substitution compatibility?

A: No. AEC-Q200 certification indicates the part has undergone additional automotive-grade qualification testing and is suitable for automotive applications. Parts with AEC-Q200 (ERJ-6ENF1403V, KTR10EZPF1403, RMCF0805FT140K, CRCW0805140KFKEA) are fully compatible with non-automotive applications and with the non-certified RC2012F1403CS. Certification is an enhancement, not a restriction.

Q: What is the significance of Moisture Sensitivity Level (MSL) 1?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and requires no special handling, storage, or baking procedures prior to soldering. All listed parts carry MSL 1 classification, ensuring identical moisture management requirements.

Q: Can I use MCR10ERTF1403 if it is discontinued?

A: MCR10ERTF1403 is discontinued at DiGi Electronics but remains electrically and mechanically equivalent. Use only if existing inventory is available and supply chain continuity is not a concern. For new designs or long-term production, select from Active status alternatives (ERJ-6ENF1403V, KTR10EZPF1403, RC0805FR-07140KL, RMCF0805FT140K, CRCW0805140KFKEA).

Q: Does packaging format (Tape & Reel versus Cut Tape) affect electrical performance?

A: No. Packaging format is a supply chain and assembly logistics consideration only. Tape & Reel (TR) is standard for automated pick-and-place assembly; Cut Tape (CT) & Digi-Reel® is suitable for manual assembly or mixed-component orders. Electrical and mechanical performance is identical regardless of packaging format.

Q: Are there any height restrictions for PCB assembly?

A: All substitute parts fit within standard 0805 package height specifications (0.50mm to 0.70mm maximum seated height). Verify PCB design clearance if space constraints exist. CRCW0805140KFKEA (0.50mm) offers the lowest profile for high-density layouts.

Q: What compliance certifications apply to all substitute parts?

A: All listed parts are ROHS3 Compliant and REACH Unaffected. These certifications ensure compliance with environmental and hazardous substance regulations. No additional compliance verification is required for substitution.
