Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F4641CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance value: 4.64 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 type: 0805 (2012 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

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

All substitute parts listed below meet these criteria. Additional features such as automotive AEC-Q200 qualification or high voltage capability represent enhancements that do not prevent substitution but indicate expanded application scope.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the RC2012F4641CS and meet identical electrical and mechanical specifications. Selection among these alternatives should be based on the following factors:

For General Industrial Applications: RC0805FR-074K64L (YAGEO) or RC2012F4641CS (Samsung Electro-Mechanics) are suitable. Both feature moisture-resistant composition and unlimited MSL rating. YAGEO offers higher inventory availability (360,912 pcs) and lower seated height (0.60mm).

For Automotive Applications: ERJ-6ENF4641V (Panasonic), KTR10EZPF4641 (Rohm), RMCF0805FT4K64 (Stackpole), or CRCW08054K64FKEA (Vishay Dale) are qualified. All carry AEC-Q200 automotive certification. KTR10EZPF4641 includes high voltage capability. CRCW08054K64FKEA offers the lowest seated height (0.50mm) for space-constrained designs.

For Supply Chain Continuity: RC0805FR-074K64L (YAGEO) with 360,912 pcs in stock provides maximum availability. ERJ-6ENF4641V (Panasonic) with 255,325 pcs offers secondary sourcing.

All parts are ROHS3 compliant, REACH unaffected, and carry unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard PCB assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC2012F4641CS with any of these parts without design changes?

A: Yes. All listed parts are electrically and mechanically equivalent. They share identical resistance (4.64 kΩ), tolerance (±1%), power rating (0.125W), package (0805), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). No circuit modifications are required.

Q: What is the difference between the main part and automotive-qualified substitutes?

A: The main part (RC2012F4641CS) is moisture-resistant general-purpose thick film resistor. Automotive substitutes (ERJ-6ENF4641V, KTR10EZPF4641, RMCF0805FT4K64, CRCW08054K64FKEA) carry AEC-Q200 qualification, indicating compliance with automotive reliability standards. Automotive parts are suitable for general applications but offer enhanced qualification documentation.

Q: Are there packaging differences I should consider?

A: The main part is supplied in Tape & Reel (TR) packaging. RC0805FR-074K64L is supplied in Cut Tape (CT) & Digi-Reel® format. All other substitutes use Tape & Reel. Packaging affects handling and assembly processes but does not impact electrical performance.

Q: What is the significance of seated height variations?

A: Seated heights range from 0.50mm (CRCW08054K64FKEA) to 0.70mm (ERJ-6ENF4641V). These variations are within normal manufacturing tolerances for 0805 package resistors. Selection should consider PCB clearance requirements and assembly equipment specifications. Lower height parts (0.50-0.60mm) are preferred for space-constrained applications.

Q: Are all parts RoHS3 compliant?

A: Yes. All listed parts carry ROHS3 compliance certification and are REACH unaffected, meeting current environmental and regulatory requirements for electronics manufacturing.

Q: Which substitute offers the best inventory availability?

A: RC0805FR-074K64L (YAGEO) with 360,912 pcs in stock provides maximum availability. This part is suitable for immediate procurement and high-volume applications.

Q: Can I use KTR10EZPF4641 in non-automotive applications?

A: Yes. KTR10EZPF4641 is a high-voltage automotive-qualified resistor that exceeds the specifications of the main part. It is fully compatible with general industrial applications and offers additional performance margin.
