RC5025J270CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025J270CS is a 27 Ohm ±5% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) surface mount package. This component is classified as Active product status with full RoHS3 compliance and MSL Level 1 moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs while maintaining the same resistance value, package footprint, and operating specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025J270CS is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Resistance value: 27 Ohms (exact match required)
• Package type: 2010 (5025 Metric) surface mount package (exact match required)
• Composition: Thick film technology (exact match required)
• Operating temperature range: -55°C ~ 155°C minimum (must encompass or equal this range)
• RoHS3 compliance status (must be maintained)
• MSL rating: Level 1 or better (equal or superior moisture sensitivity rating)

Allowable Parameter Variations:

• Tolerance: May be equal (±5%) or tighter (±1%)
• Power rating: May be equal (0.667W) or higher (0.75W or greater)
• Temperature coefficient: ±100ppm/°C or better
• Packaging format: Original specification does not restrict tape & reel format

The identified substitute parts RC2010FK-0727RL and RC2010JK-0727RL meet all mandatory criteria while offering enhanced power ratings (0.75W vs. 0.667W) and, in the case of RC2010FK-0727RL, improved tolerance specification (±1% vs. ±5%).

Parameter Comparison

Engineering Selection Recommendations

RC2010FK-0727RL Selection Criteria: This YAGEO substitute provides a tighter tolerance specification (±1% versus ±5%) while maintaining identical package geometry, operating temperature range, and regulatory compliance. The increased power rating (0.75W versus 0.667W) provides additional thermal margin. Selection is appropriate when tolerance precision is a design requirement or when thermal headroom is beneficial. Active product status and full RoHS3 compliance ensure long-term availability and regulatory alignment.

RC2010JK-0727RL Selection Criteria: This YAGEO substitute maintains the original ±5% tolerance specification while providing increased power rating (0.75W versus 0.667W). Package footprint, operating temperature range, and regulatory compliance remain identical to the main part. Selection is appropriate when tolerance specification matches design requirements and enhanced power dissipation capability is desired. Active product status and full RoHS3 compliance ensure supply continuity.

Compliance Verification: All three parts maintain ROHS3 compliance, REACH Unaffected status, and MSL Level 1 moisture sensitivity rating. No additional qualification or testing is required from a regulatory standpoint when substituting between these parts within the same application.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-0727RL or RC2010JK-0727RL be used as direct drop-in replacements for RC5025J270CS?

A: Yes. Both substitute parts share identical package dimensions (2010/5025 Metric), footprint, and mounting requirements. No PCB layout modifications are required. The 27 Ohm resistance value, operating temperature range (-55°C ~ 155°C), and regulatory compliance (RoHS3, REACH Unaffected, MSL 1) are maintained across all three parts.

Q: What is the difference between the two YAGEO substitutes?

A: RC2010FK-0727RL provides ±1% tolerance versus ±5% tolerance in RC2010JK-0727RL. Both offer identical 0.75W power rating, package type, and operating specifications. Selection depends on circuit tolerance requirements. RC2010FK-0727RL is appropriate for applications requiring tighter resistance accuracy.

Q: Does the increased power rating (0.75W vs. 0.667W) affect circuit performance?

A: No. The power rating represents maximum thermal dissipation capability. A higher power rating does not change the resistor's electrical characteristics (resistance value, tolerance, temperature coefficient). The substitute parts will perform identically in circuits designed for the original 0.667W specification.

Q: Are there any packaging format considerations?

A: The main part RC5025J270CS is supplied in bulk packaging. Both YAGEO substitutes are supplied in Tape & Reel (TR) format. This affects handling and assembly processes but does not impact electrical or mechanical compatibility. Verify that your assembly process accommodates tape & reel format if substituting.

Q: Do these substitutes require any design re-qualification?

A: No re-qualification is required from an electrical or regulatory standpoint. All parts maintain identical operating temperature ranges, RoHS3 compliance, and MSL Level 1 ratings. Mechanical compatibility is confirmed through identical package dimensions and footprints.

Q: What is the temperature coefficient significance?

A: All three parts share ±100ppm/°C temperature coefficient, meaning resistance changes by approximately 0.01% per degree Celsius across the -55°C ~ 155°C operating range. This specification is identical across main and substitute parts, ensuring equivalent thermal performance.
