Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F4222CS is determined by strict alignment of the following parameters:

Critical Electrical Parameters:

• Resistance value: 42.2 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)

Critical Mechanical Parameters:

• Package / Case: 0805 (2012 Metric) (exact match required)
• Number of terminations: 2 (exact match required)
• Supplier device package: 0805 (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• REACH Status: REACH Unaffected (exact match required)

All four substitute parts listed below meet these criteria and are therefore electrically and mechanically interchangeable with the RCS2012F4222CS.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are qualified for direct replacement with the RCS2012F4222CS based on matching electrical specifications, mechanical dimensions, and compliance certifications.

CRCW080542K2FKEA (Vishay Dale): This substitute carries AEC-Q200 automotive qualification and is supplied in Cut Tape (CT) & Digi-Reel® packaging. The seated height of 0.020" (0.50mm) is the lowest among all options, providing maximum clearance in space-constrained applications. Current inventory is 16,660 pieces.

ERJ-6ENF4222V (Panasonic Electronic Components): This substitute carries AEC-Q200 automotive qualification and is supplied in Tape & Reel (TR) packaging. The seated height of 0.028" (0.70mm) is the highest among all options. Current inventory is 184,260 pieces, representing the highest availability.

KTR10EZPF4222 (Rohm Semiconductor): This substitute carries AEC-Q200 automotive qualification with additional high voltage capability and is supplied in Tape & Reel (TR) packaging. The seated height of 0.026" (0.65mm) matches the original part closely. Current inventory is 6,259 pieces.

RC0805FR-0742K2L (YAGEO): This substitute features moisture-resistant characteristics matching the original part and is supplied in Cut Tape (CT) & Digi-Reel® packaging. The seated height of 0.024" (0.60mm) provides moderate clearance. Current inventory is 68,579 pieces.

Selection among these substitutes should be based on packaging format preference (Tape & Reel versus Cut Tape & Digi-Reel), automotive qualification requirements (AEC-Q200), and physical clearance constraints determined by seated height specifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW080542K2FKEA replace RCS2012F4222CS in all applications?

A: Yes. Both parts share identical electrical specifications (42.2 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C), mechanical package (0805 / 2012 Metric), and compliance certifications (ROHS3, REACH Unaffected, MSL 1). The primary difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and seated height (0.020" versus 0.026").

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape suitable for automated pick-and-place equipment. Cut Tape (CT) & Digi-Reel® packaging provides components on cut tape segments with reel compatibility, offering flexibility for both manual and automated assembly processes.

Q: Does AEC-Q200 qualification affect substitution compatibility?

A: AEC-Q200 is an automotive qualification standard. Three substitute parts (CRCW080542K2FKEA, ERJ-6ENF4222V, KTR10EZPF4222) carry this certification, while the original RCS2012F4222CS and RC0805FR-0742K2L do not. All parts remain electrically and mechanically interchangeable. AEC-Q200 qualification indicates additional reliability testing suitable for automotive applications.

Q: Why do seated heights vary among substitute parts?

A: Seated height variation (0.020" to 0.028") results from different manufacturing processes and thick film construction methods among manufacturers. All variations remain within acceptable tolerances for 0805 package specifications. Selection should consider PCB clearance requirements and component density in the assembly.

Q: Are all substitute parts currently in stock?

A: Yes. Current inventory levels are: ERJ-6ENF4222V (184,260 pcs), RC0805FR-0742K2L (68,579 pcs), CRCW080542K2FKEA (16,660 pcs), and KTR10EZPF4222 (6,259 pcs). The original RCS2012F4222CS has 810 pieces in stock.

Q: What does ROHS3 Compliant status indicate?

A: ROHS3 Compliant indicates the component meets Restriction of Hazardous Substances Directive 3 requirements, restricting the use of specific hazardous materials including lead, mercury, cadmium, and certain flame retardants. All listed parts and substitutes meet this standard.

Q: Can KTR10EZPF4222 be used in high voltage applications?

A: KTR10EZPF4222 carries high voltage capability designation in addition to standard specifications. However, all listed parts share identical electrical ratings (0.125W, -55°C ~ 155°C operating range). High voltage capability indicates enhanced design margin; actual voltage application limits depend on circuit design requirements.
