RC5025F6813CS Equivalent & Substitute Parts

Part Overview

The RC5025F6813CS is a 681 kOhms ±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 classified as Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same resistance value, tolerance, package footprint, and operating temperature range. The primary substitute identified is the ERJ-12SF6813U from Panasonic Electronic Components, which shares the same resistance specification and package dimensions while offering higher power rating and automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F6813CS is determined by strict alignment with the following electrical and mechanical parameters:

Critical Parameters (Must Match Exactly):

• Resistance Value: 681 kOhms
• Tolerance: ±1% (or tighter)
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2

Flexible Parameters (Can Be Equal or Exceed):

• Power Rating: Substitute must be ≥0.667W
• Moisture Sensitivity Level: MSL 1 is acceptable; lower MSL values also acceptable
• RoHS Compliance: ROHS3 or equivalent required

The ERJ-12SF6813U qualifies as a direct substitute because it maintains all critical parameters while offering enhanced power rating (0.75W vs. 0.667W) and automotive-grade qualification (AEC-Q200). The identical package dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm) and resistance specification ensure PCB-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: ERJ-12SF6813U

The ERJ-12SF6813U is electrically and mechanically compatible with the RC5025F6813CS for direct substitution in applications requiring 681 kOhms ±1% resistance in a 2010 package. The substitute maintains identical electrical specifications (resistance, tolerance, temperature coefficient, operating range) and package footprint compatibility.

Advantages of ERJ-12SF6813U:

• Higher power rating (0.75W vs. 0.667W) provides additional thermal margin
• AEC-Q200 automotive qualification enables use in automotive and high-reliability applications
• ROHS3 compliance and MSL 1 rating match the original specification
• Identical package dimensions ensure PCB layout compatibility

Considerations:

• ERJ-12SF6813U is marked "Not For New Designs," indicating Panasonic may be phasing this part. For new designs, evaluate long-term availability and consider the RC5025F6813CS (Active status) or identify alternative suppliers from the extended substitute list.
• Maximum seated height differs by 0.002" (0.04mm), which is negligible for most applications but should be verified for space-constrained designs.
• Packaging differs: RC5025F6813CS uses standard packaging; ERJ-12SF6813U is supplied in Tape & Reel format, which may affect procurement and handling procedures.

Regulatory Compliance: Both parts are ROHS3 compliant and REACH unaffected, meeting standard environmental and regulatory requirements. Both carry ECCN EAR99 classification and HTSUS code 8533.21.0030.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF6813U replace RC5025F6813CS in my circuit?

A: Yes, ERJ-12SF6813U is a direct electrical and mechanical substitute. Both parts provide 681 kOhms ±1% resistance in a 2010 (5025 Metric) package with identical temperature coefficients and operating ranges. The substitute's higher power rating (0.75W vs. 0.667W) is compatible with applications designed for the original part.

Q: What is the difference in power rating between these parts?

A: The RC5025F6813CS is rated for 0.667W (2/3W), while the ERJ-12SF6813U is rated for 0.75W (3/4W). The substitute can safely handle the same power dissipation as the original and provides additional thermal headroom. No circuit modification is required.

Q: Are the package dimensions identical?

A: The length and width are identical (0.197" L x 0.098" W / 5.00mm x 2.50mm). Maximum seated height differs slightly: RC5025F6813CS is 0.026" (0.66mm) and ERJ-12SF6813U is 0.028" (0.70mm). This 0.002" difference is negligible for standard PCB designs but should be verified for applications with tight vertical clearance constraints.

Q: What does "Not For New Designs" mean for the ERJ-12SF6813U?

A: This status indicates Panasonic may be discontinuing or limiting production of this part. While it remains available and functional, new product designs should consider the RC5025F6813CS (Active status) or evaluate alternative suppliers to ensure long-term component availability.

Q: Are both parts RoHS compliant?

A: Yes, both RC5025F6813CS and ERJ-12SF6813U are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both are REACH unaffected and carry ECCN EAR99 classification.

Q: What is the difference in packaging format?

A: The RC5025F6813CS is supplied in standard packaging, while the ERJ-12SF6813U is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume automated assembly but may require different handling and storage procedures compared to standard packaging.

Q: Can I use these parts interchangeably in automotive applications?

A: The ERJ-12SF6813U carries AEC-Q200 automotive qualification, making it suitable for automotive applications. The RC5025F6813CS does not specify automotive qualification. If automotive compliance is required, the ERJ-12SF6813U is the appropriate choice.

Q: What tolerance options are available?

A: Both parts are specified at ±1% tolerance. This tolerance is suitable for precision circuits requiring tight resistance accuracy. No alternative tolerance options are provided for these specific part numbers.

Q: Are there other substitutes available?

A: The RC5025F6813CS specification lists additional substitutes: RMCF2010FT681K, ERJ-S1DF6813U, AC2010FK-07681KL, CRCW2010681KFKTF, and RC2010FK-07681KL. These alternatives maintain the same 681 kOhms ±1% specification and 2010 package but may differ in manufacturer, composition, or additional features. Detailed parameter comparison with these alternatives should be performed before selection.
