Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F303CS is determined by strict equivalence across the following critical parameters:

Core Electrical Parameters:

• Resistance value: 30 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (minimum requirement)

Parts are classified as Direct Substitutes when all core electrical, mechanical, and compliance parameters match exactly. Parts are classified as Similar when they meet all core requirements but include additional features (such as automotive AEC-Q200 qualification or pulse withstanding capability) or differ in packaging format (Tape & Reel versus Cut Tape).

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Electrically and Mechanically Equivalent):

Frequently Asked Questions (FAQ)

Q: Can CR0805-FX-3002ELF be used as a direct replacement for RC2012F303CS?

A: Yes. CR0805-FX-3002ELF is a direct substitute. Both parts share identical resistance (30 kOhms), tolerance (±1%), power rating (0.125W), package (0805), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance status (ROHS3, MSL 1). Both feature moisture-resistant thick film composition.

Q: What is the difference between direct substitutes and qualified substitutes?

A: Direct substitutes (CR0805-FX-3002ELF, CRG0805F30K, RC0805FR-0730KL) match all electrical and mechanical specifications of the RC2012F303CS without additional features. Qualified substitutes (ERJ-6ENF3002V, KTR10EZPF3002, RMCF0805FT30K0, AC0805FR-0730KL, CRCW080530K0FKEA) meet all core specifications and additionally carry automotive AEC-Q200 qualification, making them suitable for automotive applications.

Q: Can CRCW080530K0FKEAHP replace RC2012F303CS in any circuit?

A: CRCW080530K0FKEAHP is not a direct substitute. While it maintains identical resistance, tolerance, package, and temperature specifications, it provides 0.5W (1/2W) power rating compared to the 0.125W (1/8W) rating of RC2012F303CS. This higher power rating makes it suitable only for circuits designed to accommodate or benefit from increased power dissipation capability. Use in circuits designed for 0.125W resistors requires circuit analysis to confirm compatibility.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both RC2012F303CS and all listed substitute parts carry this rating, ensuring equivalent moisture sensitivity characteristics.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RC2012F303CS and all listed substitute parts are ROHS3 compliant, meeting the same environmental and regulatory requirements.

Q: What is the significance of the 0805 (2012 Metric) package designation?

A: The 0805 (2012 Metric) package designation indicates physical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). All listed parts use this identical package, ensuring mechanical compatibility with PCB footprints designed for 0805 resistors. Minor variations in seated height (ranging from 0.020" to 0.028") do not affect PCB assembly compatibility.

Q: Can I use KTR10EZPF3002 in non-automotive applications?

A: Yes. KTR10EZPF3002 meets all electrical and mechanical specifications of RC2012F303CS and exceeds minimum requirements through automotive AEC-Q200 qualification and high voltage capability. Automotive-qualified components are suitable for general industrial and consumer applications.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for automated assembly processes. Cut Tape (CT) & Digi-Reel® packaging supplies components on cut tape segments, suitable for manual assembly or smaller production runs. Both packaging formats contain identical components; selection depends on assembly process requirements.

Q: Why would I choose ERJ-6ENF3002V with 249689 pcs inventory over other options?

A: ERJ-6ENF3002V offers the highest inventory availability among qualified substitutes, making it advantageous for large-volume production runs or long-term supply security. It maintains automotive AEC-Q200 qualification while meeting all core specifications of RC2012F303CS.
