Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F4531CS are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Parameters (Must Match):

• Resistance value: 4.53 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2
• Packaging format: Tape & Reel (TR)

Compliance Parameters (Must Match):

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these criteria. Additional features such as Automotive AEC-Q200 certification are noted where applicable but do not disqualify parts from substitution in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are qualified for direct replacement with the RC2012F4531CS based on matching electrical and mechanical specifications. Selection among equivalent parts should be based on the following factors:

For General Industrial Applications: RC0805FR-074K53L (YAGEO) provides direct electrical and mechanical equivalence without automotive-specific requirements. This part offers the lowest seated height (0.024" / 0.60mm) among all options, which may be advantageous for space-constrained PCB layouts.

For Automotive Applications: CRCW08054K53FKEA (Vishay Dale), ERJ-6ENF4531V (Panasonic), and RMCF0805FT4K53 (Stackpole) all carry AEC-Q200 automotive qualification. These parts are suitable for automotive-grade circuit designs. CRCW08054K53FKEA offers the lowest profile (0.020" / 0.50mm), while ERJ-6ENF4531V has the highest profile (0.028" / 0.70mm).

Inventory Availability: YAGEO RC0805FR-074K53L maintains the highest inventory level (184,050 pcs), followed by Stackpole RMCF0805FT4K53 (97,740 pcs) and Panasonic ERJ-6ENF4531V (82,229 pcs). Samsung RC2012F4531CS inventory is 766 pcs.

All substitute parts maintain RoHS3 compliance, MSL 1 rating, and Active product status, ensuring long-term availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-074K53L (YAGEO) be used as a direct replacement for RC2012F4531CS (Samsung)?

A: Yes. Both parts share identical electrical specifications (4.53 kOhms ±1%, 0.125W), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), package format (0805 / 2012 Metric), and compliance ratings (RoHS3, MSL 1). The YAGEO part has a slightly lower seated height (0.024" vs 0.026"), which is compatible with standard PCB assembly processes.

Q: What is the difference between automotive-rated and non-automotive substitute parts?

A: CRCW08054K53FKEA (Vishay Dale), ERJ-6ENF4531V (Panasonic), and RMCF0805FT4K53 (Stackpole) carry AEC-Q200 automotive qualification, indicating compliance with automotive reliability and testing standards. RC0805FR-074K53L (YAGEO) does not specify AEC-Q200 rating. For automotive applications, AEC-Q200 qualified parts are required. For non-automotive applications, all parts are functionally equivalent.

Q: Are there any height restrictions when substituting these parts?

A: Seated heights range from 0.020" (0.50mm) to 0.028" (0.70mm) across all parts. All heights fall within standard 0805 package specifications and are compatible with typical PCB assembly equipment and design clearances. Verify specific PCB design constraints if height-critical applications exist.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All parts, including the main part RC2012F4531CS and all substitutes, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute part offers the best supply chain availability?

A: YAGEO RC0805FR-074K53L maintains the highest inventory (184,050 pcs), providing the strongest supply chain position. Stackpole RMCF0805FT4K53 (97,740 pcs) and Panasonic ERJ-6ENF4531V (82,229 pcs) also maintain substantial inventory levels.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, all parts are mechanically and electrically interchangeable on the same PCB. The 0805 package format, identical pad dimensions (0.079" L x 0.049" W), and two-termination configuration ensure compatibility with standard pick-and-place equipment and solder reflow processes.
