Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F6653CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 665 kOhms
• Tolerance: ±1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts rated at 0.125W (1/8W) or higher are acceptable. The ERJ-P06F6653V operates at 0.5W (1/2W), which exceeds the original specification and remains compatible.
• Physical Height: Seated height variations within the 0805 package envelope are acceptable provided the component fits within PCB assembly constraints.

All identified substitute parts meet these criteria and are classified as Active product status with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are classified as Active product status and maintain ROHS3 compliance with MSL 1 rating, ensuring regulatory and environmental compatibility with the original RCS2012F6653CS component.

CRCW0805665KFKEA (Vishay Dale): Direct electrical and mechanical equivalent with automotive AEC-Q200 qualification. Seated height of 0.020" (0.50mm) is the lowest among substitutes, providing maximum PCB assembly clearance.

ERJ-6ENF6653V (Panasonic Electronic Components): Direct electrical equivalent with automotive AEC-Q200 qualification. Seated height of 0.028" (0.70mm) remains within 0805 package specifications.

ERJ-P06F6653V (Panasonic Electronic Components): Electrical equivalent with elevated power rating of 0.5W (1/2W) versus original 0.125W specification. Includes automotive AEC-Q200 qualification and pulse withstanding capability. Seated height of 0.028" (0.70mm) remains within 0805 package specifications. Selection appropriate for applications requiring enhanced power dissipation margin.

RC0805FR-07665KL (YAGEO): Direct electrical and mechanical equivalent with moisture-resistant characteristics. Seated height of 0.024" (0.60mm) provides intermediate clearance profile. Highest inventory availability at 105,342 pieces.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805665KFKEA replace RCS2012F6653CS in any application?

A: Yes. CRCW0805665KFKEA matches all critical electrical parameters (665 kOhms, ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C) and mechanical specifications (0805 package, 0.020" seated height). Both components are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between ERJ-6ENF6653V and ERJ-P06F6653V?

A: Both are Panasonic 665 kOhms ±1% 0805 resistors with identical electrical specifications and AEC-Q200 qualification. The primary difference is power rating: ERJ-6ENF6653V is rated 0.125W (1/8W), while ERJ-P06F6653V is rated 0.5W (1/2W) with pulse withstanding capability. Select ERJ-P06F6653V when circuit design requires higher power dissipation capacity.

Q: Are there height restrictions when substituting these parts?

A: All substitute parts maintain 0805 (2012 Metric) package compliance. Seated heights range from 0.020" to 0.028" (0.50mm to 0.70mm). Verify PCB assembly design clearance specifications. CRCW0805665KFKEA offers the lowest profile at 0.020" (0.50mm).

Q: Do all substitutes have the same moisture sensitivity rating?

A: Yes. RCS2012F6653CS and all identified substitutes are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute has the highest inventory availability?

A: RC0805FR-07665KL (YAGEO) has 105,342 pieces in stock, significantly exceeding other substitutes. CRCW0805665KFKEA (Vishay Dale) has 11,770 pieces, and ERJ-6ENF6653V (Panasonic) has 17,818 pieces.

Q: Are automotive-qualified substitutes required for this application?

A: Automotive AEC-Q200 qualification is present in CRCW0805665KFKEA, ERJ-6ENF6653V, and ERJ-P06F6653V. Selection depends on application requirements. Non-automotive applications may use RC0805FR-07665KL without AEC-Q200 qualification.
