Substitute Part Grouping Explanation

Substitute parts for the RC2012F6812CS are classified into two functional groups based on electrical and mechanical parameter alignment:

Group 1: Direct Electrical & Mechanical Equivalents These parts maintain identical resistance (68.1 kOhms), tolerance (±1%), power rating (0.125W / 1/8W), package (0805), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). All terminations are 2-pin configurations. These substitutes are interchangeable in applications where the original specification is required without modification.

• RC0805FR-0768K1L (YAGEO)
• ERJ-6ENF6812V (Panasonic Electronic Components)
• RMCF0805FT68K1 (Stackpole Electronics Inc)

Group 2: Electrical Equivalents with Enhanced Power Rating These parts maintain identical resistance (68.1 kOhms), tolerance (±1%), package (0805), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C), but feature increased power rating (0.5W / 1/2W). These are suitable for applications where higher power dissipation capability is beneficial or required.

• CRCW080568K1FKEA (Vishay Dale) – 0.125W / 1/8W, Automotive AEC-Q200
• CRCW080568K1FKEAHP (Vishay Dale) – 0.5W / 1/2W, Automotive AEC-Q200, Pulse Withstanding
• RCS080568K1FKEA (Vishay Dale) – 0.5W / 1/2W, Automotive AEC-Q200, Pulse Withstanding

All substitute parts comply with ROHS3, maintain MSL 1 rating, and operate within the specified temperature range.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications)

RC0805FR-0768K1L (YAGEO), ERJ-6ENF6812V (Panasonic Electronic Components), and RMCF0805FT68K1 (Stackpole Electronics Inc) are suitable direct replacements. All three maintain the 0.125W power rating, 68.1 kOhms resistance, ±1% tolerance, and 0805 package format. YAGEO's RC0805FR-0768K1L offers the lowest seated height (0.60mm) and is available in Cut Tape & Digi-Reel packaging. Panasonic's ERJ-6ENF6812V and Stackpole's RMCF0805FT68K1 are both qualified to Automotive AEC-Q200 standard, providing enhanced reliability for automotive applications. All three are ROHS3 compliant with MSL 1 rating and active production status.

For Applications Requiring Enhanced Power Dissipation

CRCW080568K1FKEAHP (Vishay Dale) and RCS080568K1FKEA (Vishay Dale) provide 0.5W (1/2W) power rating while maintaining all other electrical parameters. Both feature Automotive AEC-Q200 qualification and pulse withstanding capability. These are appropriate for circuits where thermal margin or transient power handling is a design consideration. CRCW080568K1FKEA (Vishay Dale) at 0.125W provides an intermediate option with AEC-Q200 qualification at the original power rating.

All substitute parts are ROHS3 compliant, maintain MSL 1 moisture sensitivity level, and operate within the -55°C to 155°C temperature range specified for the original component.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-0768K1L replace RC2012F6812CS directly?

A: Yes. Both parts share identical electrical specifications: 68.1 kOhms resistance, ±1% tolerance, 0.125W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both are packaged in 0805 (2012 Metric) format with 2 terminations. The primary difference is packaging type (YAGEO offers Cut Tape & Digi-Reel versus Samsung's Tape & Reel) and seated height (0.60mm versus 0.66mm). The lower height may provide advantages in space-constrained layouts.

Q: What is the difference between 0.125W and 0.5W rated substitutes?

A: Power rating indicates maximum continuous power dissipation capability. The 0.125W (1/8W) rated parts (RC0805FR-0768K1L, ERJ-6ENF6812V, RMCF0805FT68K1) are suitable for standard applications. The 0.5W (1/2W) rated parts (CRCW080568K1FKEAHP, RCS080568K1FKEA) provide four times the power dissipation capability and are appropriate for circuits with higher current flow or thermal stress. Selection depends on circuit requirements, not on part interchangeability.

Q: Are automotive-qualified parts (AEC-Q200) interchangeable with non-automotive versions?

A: From an electrical and mechanical standpoint, yes. AEC-Q200 qualification indicates additional testing and reliability screening per automotive standards. Parts with AEC-Q200 rating (CRCW080568K1FKEA, CRCW080568K1FKEAHP, ERJ-6ENF6812V, RCS080568K1FKEA, RMCF0805FT68K1) can be used in non-automotive applications without issue. However, non-automotive qualified parts should not be used in automotive applications where AEC-Q200 compliance is required.

Q: Does seated height variation affect PCB assembly?

A: Seated height differences (0.50mm to 0.70mm range) are within standard 0805 package tolerance and do not affect PCB assembly compatibility. All listed parts conform to 0805 (2012 Metric) package specification. Height variation may be relevant only in applications with extremely tight vertical clearance constraints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts, including the original RC2012F6812CS, are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level. All parts are suitable for lead-free soldering processes and meet environmental compliance requirements.

Q: What is the inventory availability difference?

A: RC2012F6812CS (Samsung) has 951 pieces in stock. Substitute availability varies: RC0805FR-0768K1L (YAGEO) has 149,911 pieces; ERJ-6ENF6812V (Panasonic) has 131,042 pieces; RMCF0805FT68K1 (Stackpole) has 242,759 pieces; CRCW080568K1FKEA (Vishay) has 18,795 pieces; CRCW080568K1FKEAHP (Vishay) has 4,731 pieces; RCS080568K1FKEA (Vishay) has 4,729 pieces. Higher inventory availability may influence supply chain decisions for high-volume production.
