Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F5111CS is determined by the following mandatory parameters:

Core Electrical Compatibility:

• Resistance value: 5.11 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)

Mechanical Compatibility:

• Package / Case: 2010 (5025 Metric) (exact match required)
• Number of Terminations: 2 (exact match required)
• Size / Dimension: 0.197" L x 0.098" W (5.00mm x 2.50mm) (exact match required)

Allowable Variations:

• Power Rating: Substitutes may have equal or higher power rating (0.75W acceptable for 0.667W requirement)
• Height - Seated (Max): Minor variations acceptable within package specification
• Features: Additional certifications (AEC-Q200) do not disqualify substitution
• Product Status: Active status preferred; Not For New Designs acceptable for legacy applications
• Packaging Format: Tape & Reel (TR) acceptable for bulk applications

All substitute parts identified meet these criteria and are electrically and mechanically interchangeable with the RC5025F5111CS.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status, General Applications): CRCW20105K11FKEF (Vishay Dale) and RMCF2010FT5K11 (Stackpole Electronics Inc) are both Active product status with higher power rating (0.75W) than the original specification. Both parts carry AEC-Q200 automotive certification and are suitable for applications requiring enhanced reliability margins. These parts are recommended for new designs and high-volume production.

Secondary Selection (Legacy Applications): ERJ-12SF5111U (Panasonic Electronic Components) carries Not For New Designs status and is suitable only for replacement or legacy system maintenance where the original part is no longer available. This part maintains full electrical and mechanical compatibility but should not be selected for new circuit designs.

Compliance Considerations: All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory and environmental compatibility with the original RC5025F5111CS specification.

Frequently Asked Questions (FAQ)

Q: Can CRCW20105K11FKEF replace RC5025F5111CS in existing designs? A: Yes. CRCW20105K11FKEF is electrically and mechanically compatible. The higher power rating (0.75W vs. 0.667W) provides additional thermal margin without affecting circuit performance. The 0.002" (0.04mm) height difference is within standard PCB assembly tolerances.

Q: What is the difference between the substitute parts? A: All three substitutes (CRCW20105K11FKEF, ERJ-12SF5111U, RMCF2010FT5K11) share identical electrical specifications and package dimensions. The primary differences are manufacturer, product status, and inventory availability. CRCW20105K11FKEF and RMCF2010FT5K11 are Active status; ERJ-12SF5111U is Not For New Designs.

Q: Why do substitute parts have higher power ratings? A: The substitute parts are rated at 0.75W (3/4W) compared to the original 0.667W (2/3W). This represents a standard power rating step in thick film resistor product lines and does not create incompatibility. The higher rating provides thermal design margin without changing electrical behavior.

Q: Are all substitutes suitable for automotive applications? A: CRCW20105K11FKEF and RMCF2010FT5K11 carry AEC-Q200 automotive certification. ERJ-12SF5111U also carries AEC-Q200 but is marked Not For New Designs. The original RC5025F5111CS does not list automotive certification. Substitutes with AEC-Q200 are suitable for automotive applications; the original part is suitable for general industrial and consumer applications.

Q: Can these parts be used interchangeably in tape and reel format? A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The original RC5025F5111CS packaging format is not specified in the provided data; however, the mechanical compatibility ensures functional interchangeability regardless of packaging format.

Q: What is the significance of MSL 1 (Unlimited) rating? A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity limitations and does not require special handling, storage, or baking procedures prior to soldering. All parts in this comparison carry this rating, ensuring consistent handling requirements.
