Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F2553CS are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Parameters:

• Resistance value: 255 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)

Mechanical Parameters:

• Package type: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Parameters:

• RoHS3 Compliant status (required)
• Moisture Sensitivity Level 1 (required)

All five identified substitute parts meet these criteria. Additional features such as automotive AEC-Q200 certification or high voltage capability represent enhanced specifications beyond the base requirements and do not disqualify substitution.

Parameter Comparison

Engineering Selection Recommendations

All five substitute parts are qualified for direct replacement of the RCS2012F2553CS based on matching electrical specifications, mechanical dimensions, and compliance certifications. Selection among substitutes may be influenced by the following factors:

Product Availability: Inventory levels vary across manufacturers. CRCW0805255KFKEA (Vishay Dale) maintains 26,439 units in stock, ERJ-6ENF2553V (Panasonic) maintains 50,962 units, and RC0805FR-07255KL (YAGEO) maintains 42,525 units, providing high availability for production requirements.

Automotive Applications: CRCW0805255KFKEA, ERJ-6ENF2553V, KTR10EZPF2553, and RMCF0805FT255K carry AEC-Q200 automotive qualification. Selection of these parts is appropriate for automotive circuit designs requiring automotive-grade component certification.

Physical Height Constraints: Seated height varies between 0.50mm and 0.70mm across substitute parts. In applications with strict PCB assembly height limitations, CRCW0805255KFKEA (0.50mm) or RC0805FR-07255KL (0.60mm) may be preferred.

Enhanced Features: KTR10EZPF2553 includes high voltage capability in addition to AEC-Q200 certification, suitable for high voltage circuit applications.

All substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 status, ensuring compatibility with standard manufacturing and storage processes.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805255KFKEA replace RCS2012F2553CS in any application?

A: Yes. CRCW0805255KFKEA meets all electrical and mechanical specifications of RCS2012F2553CS. Both components share identical resistance (255 kOhms), tolerance (±1%), power rating (0.125W), package format (0805), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL 1). Direct substitution is valid without circuit modification.

Q: What is the difference between the main part and substitute parts with AEC-Q200 certification?

A: The RCS2012F2553CS does not carry AEC-Q200 automotive qualification. Substitute parts CRCW0805255KFKEA, ERJ-6ENF2553V, KTR10EZPF2553, and RMCF0805FT255K include AEC-Q200 certification, indicating compliance with automotive reliability and quality standards. These parts are suitable for automotive applications where AEC-Q200 qualification is required. Non-automotive applications may use any of the five substitutes.

Q: Are there physical size differences between substitute parts?

A: All substitute parts use the 0805 (2012 Metric) package with identical length (2.00mm) and width (1.25mm). Seated height varies slightly: RCS2012F2553CS (0.66mm), CRCW0805255KFKEA (0.50mm), ERJ-6ENF2553V (0.70mm), KTR10EZPF2553 (0.65mm), RC0805FR-07255KL (0.60mm), and RMCF0805FT255K (0.65mm). These variations are within standard PCB assembly tolerances and do not affect electrical performance or mechanical fit in standard 0805 footprints.

Q: Which substitute part has the highest inventory availability?

A: ERJ-6ENF2553V (Panasonic Electronic Components) maintains the highest inventory with 50,962 units in stock, followed by RC0805FR-07255KL (YAGEO) with 42,525 units and CRCW0805255KFKEA (Vishay Dale) with 26,439 units. These three parts are recommended for applications requiring immediate or high-volume procurement.

Q: Can KTR10EZPF2553 be used in place of RCS2012F2553CS in standard applications?

A: Yes. KTR10EZPF2553 meets all base electrical and mechanical requirements for substitution. The high voltage capability is an additional feature that does not restrict use in standard applications. This part is suitable for both standard and high voltage circuit designs.

Q: Are all substitute parts compliant with RoHS3 and MSL 1 requirements?

A: Yes. All five substitute parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited) classification, matching the compliance profile of RCS2012F2553CS. These parts are suitable for standard manufacturing environments without additional moisture control measures.
