Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F8450CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 845 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package / Case: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected
• Packaging: Tape & Reel (TR)

All identified substitute parts meet these core requirements. Variations in maximum seated height and specific feature sets (moisture resistant vs. automotive AEC-Q200) do not affect functional substitution within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed meet the core electrical and mechanical specifications for direct substitution. Selection between the RC2012F8450CS and its equivalents is based on the following factors:

RC0805FR-07845RL (YAGEO): Direct equivalent with moisture resistant composition. Seated height of 0.024" (0.60mm) is within acceptable tolerance for standard PCB assembly. Inventory availability is 47,242 pieces.

CRCW0805845RFKEA (Vishay Dale): Includes automotive AEC-Q200 qualification in addition to standard specifications. Lowest seated height at 0.020" (0.50mm). Suitable for applications requiring automotive-grade reliability. Inventory availability is 26,667 pieces.

ERJ-6ENF8450V (Panasonic): Includes automotive AEC-Q200 qualification. Seated height of 0.028" (0.70mm). Highest inventory availability at 140,184 pieces. Suitable for applications requiring automotive-grade reliability.

All parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Selection should be based on application requirements, PCB assembly constraints, and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07845RL replace RC2012F8450CS directly?

A: Yes. Both components share identical electrical specifications (845 Ohms ±1%, 0.125W), thermal characteristics (±100ppm/°C, -55°C to 155°C), and mechanical package (0805 / 2012 Metric). Seated height difference (0.024" vs 0.026") is within standard PCB assembly tolerances.

Q: What is the difference between the Samsung part and the Vishay/Panasonic parts?

A: The primary difference is feature set. RC2012F8450CS and RC0805FR-07845RL are specified as moisture resistant. CRCW0805845RFKEA and ERJ-6ENF8450V include automotive AEC-Q200 qualification. All four parts meet identical electrical and mechanical requirements for standard applications.

Q: Are the automotive-qualified parts (CRCW0805845RFKEA, ERJ-6ENF8450V) suitable for non-automotive applications?

A: Yes. Automotive-qualified components exceed standard reliability requirements and are fully compatible with non-automotive applications. AEC-Q200 qualification is an additional qualification level, not a restriction.

Q: Does seated height variation affect PCB assembly compatibility?

A: Seated height variations (0.020" to 0.028") are within standard 0805 package tolerances and do not affect PCB assembly compatibility or reflow soldering processes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. All parts are electrically and mechanically equivalent within the specified parameters. No design modifications are required for substitution.
