Key Parameters

Substitute Part Grouping Explanation

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

Critical Parameters (Must Match Exactly):

• Resistance value: 143 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3
• MSL rating: 1 (Unlimited)

Allowable Variations (Non-Critical):

• Manufacturer identity
• Series designation
• Height seated (maximum): 0.020" to 0.028" (0.50mm to 0.70mm)
• Packaging format: Tape & Reel or Cut Tape variants
• Additional certifications: Automotive AEC-Q200 qualification (enhancement, not requirement)
• Moisture resistance feature designation (enhancement, not requirement)

All identified substitute parts meet or exceed the electrical and mechanical specifications of the RC2012F1433CS.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Active Production):

ERJ-6ENF1433V (Panasonic), RC0805FR-07143KL (YAGEO), RMCF0805FT143K (Stackpole), and CRCW0805143KFKEA (Vishay Dale) are functionally equivalent to RC2012F1433CS. All maintain identical electrical specifications and ROHS3 compliance. Selection among these parts depends on:

• Automotive applications: ERJ-6ENF1433V, RMCF0805FT143K, and CRCW0805143KFKEA carry AEC-Q200 qualification, suitable for automotive-grade requirements.
• Standard industrial applications: RC0805FR-07143KL and RC2012F1433CS provide moisture-resistant thick film construction without automotive certification overhead.
• Inventory availability: CRCW0805143KFKEA (23,998 pcs), ERJ-6ENF1433V (49,421 pcs), and RC0805FR-07143KL (8,663 pcs) offer higher stock levels than RC2012F1433CS (717 pcs).
• PCB height constraints: CRCW0805143KFKEA has the lowest seated height (0.50mm), beneficial for space-constrained designs.

Discontinued Part:

MCR10ERTF1433 (Rohm Semiconductor) is discontinued at DiGi Electronics. While electrically equivalent, this part should not be selected for new designs or long-term production requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC2012F1433CS with any of the listed parts without circuit redesign?

A: Yes. All listed active parts (ERJ-6ENF1433V, RC0805FR-07143KL, RMCF0805FT143K, CRCW0805143KFKEA) are electrically and mechanically equivalent. They share identical resistance, tolerance, power rating, package, temperature coefficient, and operating range. No circuit redesign is required.

Q: What is the difference between "Direct" and "Similar" substitute classifications?

A: Direct substitutes (ERJ-6ENF1433V, RC0805FR-07143KL, RMCF0805FT143K) are listed as equivalent alternatives by the original manufacturer. Similar substitutes (CRCW0805143KFKEA, MCR10ERTF1433) meet all electrical and mechanical criteria but may have minor feature variations such as automotive certification or packaging format.

Q: Are the automotive-qualified parts (AEC-Q200) suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification is an enhancement that exceeds standard industrial requirements. Automotive-qualified parts function identically in standard industrial, consumer, and commercial applications.

Q: Does the height difference (0.50mm to 0.70mm) affect PCB assembly?

A: Height variation is within standard 0805 package tolerance and does not affect assembly compatibility. However, designs with strict height constraints should specify CRCW0805143KFKEA (0.50mm maximum) or RC0805FR-07143KL (0.60mm maximum).

Q: Why is MCR10ERTF1433 marked as discontinued?

A: MCR10ERTF1433 is discontinued at DiGi Electronics, the primary distributor listed. While electrically equivalent, this part should not be selected for new designs due to limited future availability.

Q: Can I mix different manufacturers' parts in the same production batch?

A: Yes. All active substitute parts are ROHS3 compliant with MSL 1 rating and identical electrical specifications. Mixed sourcing is permissible from a technical standpoint, though procurement and quality assurance procedures should address supplier qualification and traceability requirements.

Q: What packaging formats are available?

A: RC2012F1433CS, ERJ-6ENF1433V, RC0805FR-07143KL, RMCF0805FT143K, and CRCW0805143KFKEA are supplied in Tape & Reel (TR) format. MCR10ERTF1433 is available in Cut Tape (CT) and Digi-Reel® format. Tape & Reel is standard for high-volume automated assembly.
