Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025J271CS are qualified based on the following substitution criteria:

Mandatory Compatibility Parameters:

• Resistance value: 270 Ohms (exact match required)
• Package / Case: 2010 (5025 Metric) (physical footprint must be identical)
• Composition: Thick Film (technology type must match)
• Features: Moisture Resistant (environmental protection must be maintained)
• Temperature Coefficient: ±100ppm/°C (stability specification must match)
• Operating Temperature Range: -55°C ~ 155°C (functional range must be maintained or exceeded)
• RoHS Status: ROHS3 Compliant (regulatory requirement must be met)
• Moisture Sensitivity Level: 1 (Unlimited) (handling requirement must be maintained)

Allowable Variation Parameters:

• Tolerance: ±5% or better (tighter tolerance is acceptable as upgrade)
• Power Rating: 0.667W (2/3W) or higher (increased power rating is acceptable as upgrade)
• Manufacturer: Different manufacturers permitted if all mandatory parameters are met
• Packaging Format: Tape & Reel (TR) acceptable as alternative to standard packaging

The two identified substitute parts (RC2010FK-07270RL and RC2010JK-07270RL) both meet all mandatory compatibility parameters and represent upgrades in power rating (0.75W vs. 0.667W) while maintaining or improving tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

RC2010FK-07270RL (YAGEO) - Primary Upgrade Substitute: This substitute provides enhanced performance specifications with ±1% tolerance (improved from ±5%) and increased power rating of 0.75W (upgraded from 0.667W). All mandatory compatibility parameters are satisfied. ROHS3 compliance and REACH Unaffected status maintain regulatory alignment with the original component. Physical dimensions and thermal characteristics remain equivalent. This part is suitable for applications requiring tighter tolerance control or higher thermal margin.

RC2010JK-07270RL (YAGEO) - Direct Tolerance-Matched Substitute: This substitute maintains the ±5% tolerance specification of the original RC5025J271CS while providing increased power rating of 0.75W. All mandatory compatibility parameters are satisfied. ROHS3 compliance and REACH Unaffected status maintain regulatory alignment. Physical dimensions and thermal characteristics remain equivalent. This part is suitable for direct replacement applications where tolerance specification must be preserved and enhanced thermal headroom is beneficial.

Both substitute parts are manufactured by YAGEO and supplied in Tape & Reel (TR) packaging format. Selection between these two substitutes depends on tolerance requirements: RC2010FK-07270RL for applications requiring ±1% tolerance, or RC2010JK-07270RL for applications requiring ±5% tolerance matching the original specification.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-07270RL and RC2010JK-07270RL be used interchangeably with RC5025J271CS?

A: Both YAGEO parts are electrically and mechanically compatible with RC5025J271CS. The primary difference is tolerance: RC2010FK-07270RL provides ±1% tolerance, while RC2010JK-07270RL maintains ±5% tolerance. Selection depends on circuit tolerance requirements. Both parts share identical resistance value (270 Ohms), package form factor (2010/5025 Metric), physical dimensions, operating temperature range (-55°C ~ 155°C), and regulatory compliance (ROHS3, REACH Unaffected).

Q: What is the significance of the power rating upgrade from 0.667W to 0.75W?

A: The substitute parts provide 12.5% higher power dissipation capability. This upgrade does not affect circuit operation but provides additional thermal margin. In applications where the original 0.667W rating was marginal, the 0.75W rating reduces component stress and extends operational life. The upgrade is transparent to circuit design and does not require modification.

Q: Are the physical dimensions identical between the main part and substitutes?

A: Physical dimensions are equivalent. All three parts use the 2010 (5025 Metric) package with dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm). Maximum seated height is 0.026" (0.66mm for RC5025J271CS, 0.65mm for YAGEO parts). These minimal height differences do not affect PCB layout or assembly compatibility.

Q: What packaging formats are available?

A: The original RC5025J271CS is supplied in standard packaging format. The substitute parts RC2010FK-07270RL and RC2010JK-07270RL are supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume automated assembly and is compatible with standard pick-and-place equipment.

Q: Are all parts RoHS3 compliant?

A: Yes. RC5025J271CS, RC2010FK-07270RL, and RC2010JK-07270RL are all ROHS3 Compliant. REACH status is Unaffected for all three parts. ECCN classification is EAR99 for all parts. HTSUS code is 8533.21.0030 for all parts. Regulatory compliance is maintained across all substitution options.

Q: What is the temperature coefficient specification and why does it matter?

A: All three parts specify ±100ppm/°C temperature coefficient. This parameter defines resistance value drift across the operating temperature range (-55°C ~ 155°C). The identical specification ensures predictable performance across temperature extremes and maintains circuit stability in thermal cycling applications.

Q: What does Moisture Sensitivity Level (MSL) 1 (Unlimited) mean?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. No baking or desiccant storage is required. This specification is maintained across all three parts, simplifying inventory management and logistics.
