RC5025F4870CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F4870CS is a 487 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 with 1050 pieces available in new original inventory.

The RC5025F4870CS is designed for applications requiring moisture-resistant thick film construction with tight tolerance specifications. Equivalent and substitute parts are identified based on matching electrical characteristics (resistance value and tolerance), power rating compatibility, package dimensions, and thermal operating range. Substitutes may be necessary due to supply chain availability, design requirement changes, or specific application certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F4870CS is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Resistance value: 487 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)

Mechanical & Package Compatibility Requirements:

• Package type: 2010 (5025 Metric) surface mount package (exact match required)
• Composition: Thick film construction (exact match required)
• Number of terminations: 2 (exact match required)
• Physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) (exact match required)

Power Rating Consideration: Substitute parts must have a power rating equal to or greater than 0.667W (2/3W). Higher power ratings are acceptable for direct substitution provided all other parameters match.

Compliance & Certification:

• RoHS3 compliance required
• Moisture Sensitivity Level 1 (Unlimited) required
• REACH Unaffected status required

The ERJ-12SF4870U from Panasonic Electronic Components meets all electrical and mechanical compatibility criteria with the RC5025F4870CS, with the exception of an increased power rating of 0.75W (3/4W), which is acceptable for substitution purposes.

Parameter Comparison

Engineering Selection Recommendations

Primary Component (RC5025F4870CS): The RC5025F4870CS maintains active production status and is recommended for new design implementations. This component is suitable for applications requiring moisture-resistant thick film construction with standard commercial operating conditions. Current inventory of 1050 pieces supports immediate procurement requirements.

Substitute Component (ERJ-12SF4870U): The ERJ-12SF4870U from Panasonic Electronic Components is electrically and mechanically compatible with the RC5025F4870CS. This substitute is qualified to AEC-Q200 automotive standards, providing enhanced reliability certification for automotive and high-reliability applications. However, the ERJ-12SF4870U carries a "Not For New Designs" product status designation, indicating that Panasonic does not recommend this part for new design implementations. The substitute should be considered only for replacement, repair, or legacy system support where automotive-grade qualification is beneficial and design freeze conditions permit its use.

The increased power rating of 0.75W (3/4W) on the ERJ-12SF4870U compared to the 0.667W (2/3W) rating of the RC5025F4870CS presents no compatibility issues for direct substitution, as higher power ratings provide additional thermal margin.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-12SF4870U directly replace the RC5025F4870CS in existing designs?

A: Yes, the ERJ-12SF4870U is electrically and mechanically compatible with the RC5025F4870CS. Both components share identical resistance (487 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), package type (2010/5025 Metric), and composition (thick film). The higher power rating of the ERJ-12SF4870U (0.75W versus 0.667W) is acceptable for direct substitution. Physical dimensions are equivalent within manufacturing tolerances.

Q: Why does the ERJ-12SF4870U have a higher power rating than the RC5025F4870CS?

A: Power rating differences between equivalent resistors of the same package type reflect different thermal design approaches by manufacturers. The ERJ-12SF4870U's 0.75W rating provides additional thermal dissipation capability compared to the RC5025F4870CS's 0.667W rating. For substitution purposes, a higher power rating is compatible and does not create design conflicts.

Q: What is the significance of the "Not For New Designs" status on the ERJ-12SF4870U?

A: The "Not For New Designs" designation indicates that Panasonic does not recommend the ERJ-12SF4870U for incorporation into new product designs. This status typically reflects manufacturer lifecycle management decisions. The ERJ-12SF4870U remains suitable for replacement, repair, and legacy system support. For new designs, the RC5025F4870CS (active status) is the recommended choice.

Q: Are there any height differences between these components that affect PCB layout?

A: The RC5025F4870CS has a maximum seated height of 0.026" (0.66mm), while the ERJ-12SF4870U has a maximum seated height of 0.028" (0.70mm). This 0.002" (0.04mm) difference is within standard PCB assembly tolerances and does not create layout conflicts for typical applications. Both components are suitable for standard surface mount assembly processes.

Q: Does the AEC-Q200 qualification on the ERJ-12SF4870U provide additional benefits?

A: The AEC-Q200 automotive qualification on the ERJ-12SF4870U indicates compliance with automotive industry reliability and quality standards. This certification is beneficial for applications requiring automotive-grade component qualification. The RC5025F4870CS does not carry AEC-Q200 designation. Selection between these components should consider application-specific automotive requirements.

Q: Are moisture sensitivity levels identical between these components?

A: Yes, both the RC5025F4870CS and ERJ-12SF4870U carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. Both components are suitable for standard storage and handling conditions without special moisture control requirements.

Q: What compliance certifications apply to both components?

A: Both the RC5025F4870CS and ERJ-12SF4870U are ROHS3 compliant and REACH Unaffected. These certifications confirm compliance with environmental and hazardous substance restrictions applicable to electronic components in regulated markets.
