RC0603F6812CS Equivalent & Substitute Parts

Part Overview

The RC0603F6812CS is a 68.1 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.05W (1/20W) in a 0201 (0603 Metric) package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). The RC0603F6812CS is supplied in Cut Tape (CT) packaging format. Equivalent and substitute parts are identified when they maintain identical electrical specifications, mechanical dimensions, and compliance certifications while potentially offering alternative sourcing, packaging formats, or enhanced performance characteristics within the allowed parameter range.

Substitute Part Grouping Explanation

Substitute parts for the RC0603F6812CS are identified based on strict electrical and mechanical parameter matching. The substitution logic is as follows:

Primary Substitution Criteria (Non-Negotiable):

• Resistance value must be exactly 68.1 kOhms
• Tolerance must be ±1%
• Power rating must be 0.05W (1/20W) or higher
• Package must be 0201 (0603 Metric)
• Composition must be Thick Film
• Number of terminations must be 2
• RoHS3 compliance is mandatory

Secondary Substitution Criteria (Allowed Variations):

• Operating temperature range: Substitute must cover the minimum range of -55°C ~ 125°C or extend beyond it
• Temperature coefficient: Substitute with ±100ppm/°C or better (lower value) is acceptable as it indicates superior stability
• Moisture sensitivity level: MSL 1 (Unlimited) is acceptable; no degradation permitted
• Packaging format: Cut Tape (CT) and Tape & Reel (TR) are interchangeable for component-level selection, though supply chain and handling may differ

The CRCW020168K1FKED from Vishay Dale meets all primary and secondary criteria and is therefore a valid substitute for the RC0603F6812CS.

Parameter Comparison

Engineering Selection Recommendations

RC0603F6812CS (Samsung Electro-Mechanics) is recommended for applications requiring:

• Cut Tape (CT) packaging format for lower-volume or manual assembly processes
• Moisture-resistant thick film composition with ±250ppm/°C temperature coefficient
• Operating temperature range of -55°C to 125°C
• Established Samsung supply chain and inventory availability (13,248 Pcs in stock)

CRCW020168K1FKED (Vishay Dale) is recommended for applications requiring:

• Tape & Reel (TR) packaging format for high-volume automated assembly processes
• Superior temperature coefficient stability at ±100ppm/°C for precision applications
• Extended operating temperature range of -55°C to 155°C for high-temperature environments
• Vishay Dale supply chain and inventory availability (10,558 Pcs in stock)

Both parts maintain identical electrical specifications (68.1 kOhms ±1%, 0.05W), mechanical dimensions (0201 package), and regulatory compliance (ROHS3, REACH Unaffected, EAR99). Selection between these two substitutes should be based on packaging requirements, temperature performance needs, and supply chain preferences rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can CRCW020168K1FKED replace RC0603F6812CS in all applications?

A: Yes, CRCW020168K1FKED is electrically and mechanically compatible with RC0603F6812CS. Both components have identical resistance (68.1 kOhms ±1%), power rating (0.05W), package size (0201), and regulatory compliance. The primary difference is packaging format (Tape & Reel vs. Cut Tape) and the CRCW020168K1FKED offers superior temperature coefficient (±100ppm/°C vs. ±250ppm/°C) and extended operating temperature range (-55°C ~ 155°C vs. -55°C ~ 125°C).

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape (CT) packaging supplies components in shorter tape lengths, typically used for lower-volume or manual assembly operations. Tape & Reel (TR) packaging supplies components on continuous reels, optimized for high-volume automated pick-and-place assembly. Both formats contain identical components; the difference is in supply and handling logistics.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both RC0603F6812CS and CRCW020168K1FKED are ROHS3 compliant, REACH Unaffected, classified as EAR99, and share the same HTSUS code (8533.21.0030). Both have MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture-related handling restrictions.

Q: Why does CRCW020168K1FKED have a lower temperature coefficient?

A: Temperature coefficient (±100ppm/°C vs. ±250ppm/°C) indicates the rate of resistance change with temperature. A lower temperature coefficient value represents superior stability across temperature variations. CRCW020168K1FKED's ±100ppm/°C provides tighter resistance tolerance maintenance in temperature-sensitive applications compared to RC0603F6812CS's ±250ppm/°C.

Q: Can I use these parts interchangeably in PCB assembly?

A: Yes, from an electrical and mechanical standpoint. Both components have identical footprints (0201 package, 0.60mm x 0.30mm), identical termination count (2), and identical height (0.010" max). PCB design files do not require modification. However, assembly process parameters (tape format, reel specifications) may differ between suppliers.

Q: What should I consider when selecting between these two substitutes?

A: Consider three factors: (1) Packaging format—choose CT for manual/low-volume assembly or TR for automated high-volume assembly; (2) Temperature performance—choose CRCW020168K1FKED if operating above 125°C or if superior temperature stability is required; (3) Supply chain—choose based on inventory availability, lead time, and preferred supplier relationship.

Q: Are there any other substitute parts available for RC0603F6812CS?

A: Based on the provided data, CRCW020168K1FKED is the identified direct substitute. The RC0603F6812CS specification list also references CRCW020168K1FNED as an alternative within the Vishay Dale CRCW series, though detailed parameters for that part are not provided in this reference.
