RC5025F6810CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F6810CS is a 681 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.667W (2/3W) in a 2010 (5025 Metric) package. This component is classified as Active product status with 1,064 units currently in stock. The part is designed for general-purpose applications requiring moisture-resistant thick film construction with standard industrial temperature range operation.

Substitute parts are necessary when the original manufacturer part becomes unavailable, when design requirements demand enhanced power ratings or automotive-grade certifications, or when supply chain optimization requires alternative sourcing from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F6810CS is determined by strict adherence to the following parameters:

Mandatory Matching Parameters:

• Resistance Value: 681 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Package Type: 2010 (5025 Metric) (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to +155°C (exact match required)
• Composition: Thick Film (exact match required)

Allowable Variation Parameters:

• Power Rating: Substitute parts may have equal or higher power ratings (0.667W or greater)
• Features: Substitute parts may include additional certifications (AEC-Q200 automotive qualification) without affecting base functionality
• Moisture Sensitivity Level: MSL 1 rating maintained across all substitutes

All four substitute parts listed meet these criteria with identical electrical specifications and package dimensions. Three of the four substitutes feature enhanced power ratings of 0.75W (3/4W) and automotive AEC-Q200 certification, providing design margin and expanded application scope while maintaining full backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

AC2010FK-07681RL (YAGEO), CRCW2010681RFKEF (Vishay Dale), and RMCF2010FT681R (Stackpole) are all classified as Active products with current manufacturing support. These three parts are suitable for new designs and ongoing production. All three include AEC-Q200 automotive qualification, which provides additional design margin and reliability assurance beyond the base RC5025F6810CS specification. The enhanced 0.75W power rating offers thermal headroom in applications where the original 0.667W rating approaches maximum dissipation limits.

Secondary Substitute (Legacy Status):

ERJ-12SF6810U (Panasonic Electronic Components) carries a "Not For New Designs" product status classification. While electrically and mechanically equivalent with identical electrical parameters and AEC-Q200 certification, this part should be reserved for replacement and repair of existing assemblies only. New design implementations should utilize one of the three Active-status alternatives.

Compliance Verification:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing processes and storage requirements. All parts are classified as EAR99 for export control purposes and carry identical HTSUS commodity codes.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RC5025F6810CS with a part rated at 0.75W instead of 0.667W?

A: Yes. The substitute parts AC2010FK-07681RL, CRCW2010681RFKEF, ERJ-12SF6810U, and RMCF2010FT681R all feature 0.75W power ratings. A higher power rating is a direct upgrade that maintains full backward compatibility. The component will operate within the same thermal envelope with additional dissipation capability.

Q: Are all substitute parts automotive-qualified?

A: Three of the four substitutes (AC2010FK-07681RL, CRCW2010681RFKEF, and RMCF2010FT681R) carry AEC-Q200 automotive qualification. The original RC5025F6810CS does not specify AEC-Q200 certification. ERJ-12SF6810U also includes AEC-Q200 but is classified as "Not For New Designs."

Q: What is the difference between the packaging options listed?

A: The substitute parts are supplied in different packaging formats: AC2010FK-07681RL and ERJ-12SF6810U are supplied in Tape & Reel (TR) format. CRCW2010681RFKEF is available in Cut Tape (CT) & Digi-Reel® format. RMCF2010FT681R is supplied in Tape & Reel (TR) format. All parts use identical 2010 (5025 Metric) package geometry and PCB footprint.

Q: Can I use ERJ-12SF6810U in a new product design?

A: No. ERJ-12SF6810U is classified as "Not For New Designs" by Panasonic Electronic Components. This designation indicates the manufacturer is phasing out this product line. For new designs, select from AC2010FK-07681RL, CRCW2010681RFKEF, or RMCF2010FT681R, all of which carry Active product status.

Q: Are the physical dimensions identical across all parts?

A: Yes. All parts conform to the 2010 (5025 Metric) package standard with dimensions of 0.197" L × 0.098" W (5.00mm × 2.50mm). Maximum seated heights range from 0.026" to 0.028" (0.65mm to 0.70mm), which is within standard PCB assembly tolerances and does not affect interchangeability.

Q: What is the inventory status for each substitute?

A: Current stock levels are: RC5025F6810CS (1,064 pcs), AC2010FK-07681RL (1,438 pcs), CRCW2010681RFKEF (3,342 pcs), ERJ-12SF6810U (5,778 pcs), and RMCF2010FT681R (1,072 pcs). CRCW2010681RFKEF and ERJ-12SF6810U offer the highest inventory availability.

Q: Do all parts meet RoHS and REACH compliance requirements?

A: Yes. All parts listed are ROHS3 compliant and REACH unaffected. All carry identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications for regulatory and export control purposes.
