Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC5025F271CS is based on strict electrical and mechanical parameter matching within the thick film chip resistor category. The following criteria determine valid substitutes:

Mandatory Matching Parameters:

• Resistance value: 270 Ohms (exact match required)
• Tolerance: ±1% (no degradation permitted)
• Package format: 2010 (5025 Metric) (PCB footprint compatibility)
• Composition: Thick Film (material consistency)
• Temperature Coefficient: ±100ppm/°C (stability requirement)
• Operating Temperature Range: -55°C ~ 155°C minimum (environmental coverage)
• Moisture Resistance: Required feature
• RoHS3 Compliance: Mandatory regulatory status
• MSL Rating: Level 1 or better (storage compatibility)

Allowable Variation:

• Power Rating: Substitute may exceed 0.667W; higher ratings provide design margin and are mechanically compatible within the 2010 package envelope

The RC2010FK-07270RL from YAGEO qualifies as a valid substitute based on these criteria, offering identical electrical specifications with an increased power rating of 0.75W (3/4W) within the same package footprint.

Parameter Comparison

Engineering Selection Recommendations

The RC2010FK-07270RL from YAGEO is a qualified substitute for the RC5025F271CS from Samsung Electro-Mechanics based on the following engineering criteria:

Electrical Compatibility: Both components provide identical resistance value (270 Ohms) and tolerance (±1%), ensuring circuit performance remains unchanged. Temperature coefficient specifications are identical at ±100ppm/°C, maintaining stability across the full operating temperature range of -55°C to 155°C.

Mechanical Compatibility: Both parts utilize the 2010 (5025 Metric) package format with matching footprint dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm). Seated heights are within 0.01mm of each other, confirming PCB assembly compatibility without design modification.

Power Rating Consideration: The YAGEO substitute provides 0.75W (3/4W) power rating compared to the Samsung original's 0.667W (2/3W). This represents a 12.5% increase in power dissipation capability within the identical package envelope, providing additional thermal margin for circuit operation.

Regulatory and Compliance Status: Both components maintain RoHS3 compliance and MSL Level 1 (Unlimited) rating, confirming equivalent environmental and regulatory standing. REACH status is unaffected for both parts, and ECCN/HTSUS classifications are identical.

Product Status: Both components carry Active product status, indicating ongoing manufacturer support and availability.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-07270RL replace RC5025F271CS in existing designs without PCB modification?

A: Yes. Both components share identical 2010 (5025 Metric) package dimensions and footprint specifications. No PCB layout changes are required for direct substitution.

Q: Does the higher power rating of RC2010FK-07270RL (0.75W vs 0.667W) affect circuit performance?

A: No. Higher power rating indicates greater thermal capacity within the same package. The component will operate at identical voltage and current levels as the original. The increased rating provides additional safety margin without changing electrical behavior.

Q: Are the tolerance and temperature coefficient specifications identical between these parts?

A: Yes. Both components specify ±1% tolerance and ±100ppm/°C temperature coefficient. Circuit accuracy and temperature stability remain unchanged with substitution.

Q: What is the operating temperature range for both components?

A: Both RC5025F271CS and RC2010FK-07270RL operate across -55°C to 155°C. This range is identical for both parts.

Q: Are there any moisture sensitivity or storage differences between these components?

A: No. Both components carry MSL Level 1 (Unlimited) rating, indicating identical moisture sensitivity classification and unlimited shelf life under standard storage conditions. No special handling or baking procedures are required for either part.

Q: Do both components meet current regulatory requirements?

A: Yes. Both parts are RoHS3 compliant and REACH unaffected. Regulatory status is equivalent for both components.

Q: What is the primary reason to substitute RC2010FK-07270RL for RC5025F271CS?

A: Substitution occurs when Samsung Electro-Mechanics RC5025F271CS inventory is unavailable or lead times are extended. The YAGEO RC2010FK-07270RL provides identical electrical and mechanical specifications with confirmed availability, enabling design continuity and production scheduling.

Q: Are there any differences in packaging format between these components?

A: The RC5025F271CS is supplied in standard packaging, while RC2010FK-07270RL is supplied in Tape & Reel (TR) format. Both formats are compatible with standard PCB assembly equipment. Tape & Reel packaging may offer advantages for high-volume production environments.
