RC5025F82R5CS Equivalent & Substitute Parts

Part Overview

The RC5025F82R5CS is a 82.5 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) surface mount package. This component is currently in active production status and features moisture-resistant construction suitable for general industrial applications.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit the use of alternative manufacturers' components with equivalent or superior electrical and mechanical characteristics. The ERJ-12SF82R5U from Panasonic Electronic Components serves as a direct functional equivalent, though it carries a "Not For New Designs" status and offers increased power rating capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F82R5CS is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 82.5 Ohms (exact match required)
• Tolerance: ±1% (equivalent or tighter tolerance acceptable)
• Package designation: 2010 (5025 Metric) (identical footprint required)
• Composition: Thick Film (determines electrical characteristics)
• Temperature Coefficient: ±100ppm/°C (equivalent performance)
• Operating Temperature Range: -55°C ~ 155°C (minimum coverage required)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

Flexible Parameters:

• Power Rating: Substitute parts rated at 0.75W (3/4W) or higher are acceptable, as they provide equal or superior thermal capability
• Moisture Sensitivity Level: MSL 1 is equivalent across candidates
• Packaging format: Tape & Reel (TR) is compatible with bulk component handling

The ERJ-12SF82R5U meets all mandatory parameters and exceeds the power rating specification, making it a valid substitute despite its "Not For New Designs" status.

Parameter Comparison

Engineering Selection Recommendations

Primary Component (RC5025F82R5CS): The RC5025F82R5CS is the preferred selection for new designs. It maintains active production status, ensuring long-term availability and supply chain stability. The component is ROHS3 compliant and carries MSL 1 rating, indicating no moisture sensitivity constraints during storage and handling. The moisture-resistant thick film construction provides reliable performance across the full -55°C to 155°C operating range.

Substitute Component (ERJ-12SF82R5U): The ERJ-12SF82R5U from Panasonic Electronic Components is electrically and mechanically compatible with the RC5025F82R5CS. All critical parameters align: resistance value, tolerance, temperature coefficient, operating temperature range, package dimensions, and RoHS compliance. The substitute component provides a higher power rating (0.75W versus 0.667W), which represents a thermal margin advantage in applications approaching the primary component's power dissipation limit.

However, the ERJ-12SF82R5U carries a "Not For New Designs" designation from Panasonic. This status indicates the manufacturer is transitioning away from this product line. For new circuit designs with extended production lifecycles, the RC5025F82R5CS is the appropriate selection. The ERJ-12SF82R5U is suitable for legacy system maintenance, repair operations, or applications with limited production volumes where supply of the primary component is unavailable.

Compliance Considerations: Both components satisfy ROHS3 compliance requirements and carry identical MSL 1 ratings. No regulatory or environmental constraints differentiate the two options. The 0.002" (0.04mm) difference in maximum seated height between the two components is within typical PCB assembly tolerances and does not present a compatibility issue.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-12SF82R5U be used as a direct replacement for the RC5025F82R5CS in existing designs?

A: Yes. The ERJ-12SF82R5U is electrically and mechanically compatible. Both components share identical resistance values (82.5 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and 2010 (5025 Metric) package footprint. The substitute component's higher power rating (0.75W versus 0.667W) provides additional thermal capability without affecting circuit function.

Q: Why does the ERJ-12SF82R5U carry a "Not For New Designs" status?

A: "Not For New Designs" is a manufacturer lifecycle designation indicating that Panasonic is discontinuing or has discontinued active development of this product line. This status does not affect the component's electrical performance or reliability. It reflects the manufacturer's product portfolio strategy and does not imply technical deficiency. The designation is relevant only for long-term supply planning in new product development.

Q: Are there physical footprint differences between these components?

A: Both components use the 2010 (5025 Metric) package with identical length (0.197" / 5.00mm) and width (0.098" / 2.50mm) dimensions. The maximum seated height differs by 0.002" (0.04mm): RC5025F82R5CS at 0.026" (0.66mm) and ERJ-12SF82R5U at 0.028" (0.70mm). This variance is within standard PCB assembly tolerances and does not present a compatibility issue.

Q: What is the significance of the ±100ppm/°C temperature coefficient?

A: The temperature coefficient specifies how the resistance value changes with temperature. At ±100ppm/°C, the resistance will drift by a maximum of 0.01% per degree Celsius across the operating range. Both the RC5025F82R5CS and ERJ-12SF82R5U share this specification, ensuring equivalent temperature stability performance.

Q: Are both components suitable for automotive applications?

A: The RC5025F82R5CS is a general industrial component without automotive qualification. The ERJ-12SF82R5U carries AEC-Q200 automotive qualification, indicating it meets automotive reliability and environmental stress testing standards. If automotive qualification is required, the ERJ-12SF82R5U is the appropriate selection, though its "Not For New Designs" status should be considered for long-term supply planning.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both the RC5025F82R5CS and ERJ-12SF82R5U carry this rating, eliminating moisture-related storage constraints and simplifying inventory management.

Q: Can the higher power rating of the ERJ-12SF82R5U affect circuit performance?

A: No. Power rating specifies the maximum thermal dissipation capability, not the actual power dissipated. The substitute component's 0.75W rating (versus 0.667W for the primary component) provides additional thermal margin without changing electrical behavior. The component will dissipate only the power required by the circuit, regardless of its rated capacity.

Q: Are both components RoHS compliant?

A: Yes. Both the RC5025F82R5CS and ERJ-12SF82R5U are ROHS3 compliant, confirming lead-free construction and compliance with restricted substance regulations.
