Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F6812CS is determined by strict equivalence across the following critical parameters: resistance value (68.1 kOhms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). All identified substitute parts meet these core electrical and mechanical specifications.

Substitute parts are grouped into three categories based on additional characteristics:

Direct Equivalents maintain identical power ratings (0.063W / 1/16W), packaging format (Tape & Reel or Cut Tape), and moisture-resistant properties where applicable. These parts are interchangeable without circuit redesign.

Upgrade Parts provide enhanced power ratings (0.1W / 1/10W) or automotive-grade certifications (AEC-Q200) while maintaining all core electrical parameters. These parts support higher thermal stress applications and automotive environments.

Similar Parts include automotive-qualified variants (AEC-Q200) with identical electrical specifications but may differ in packaging format, height specifications, or moisture-resistant features. These parts are suitable for applications requiring automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Identical Specifications):

CR0402-FX-6812GLF (Bourns Inc.) and RC0402FR-0768K1L (YAGEO) are direct electrical equivalents with matching power ratings and operating parameters. Both are ROHS3 compliant and maintain the 0402 package format. RC0402FR-0768K1L includes moisture-resistant construction matching the primary part. Selection between these options depends on packaging preference (Tape & Reel versus Cut Tape & Digi-Reel) and inventory availability.

For Automotive Applications:

AC0402FR-0768K1L (YAGEO), CRCW040268K1FKED (Vishay Dale), and RMCF0402FT68K1 (Stackpole Electronics Inc) are qualified to AEC-Q200 automotive standards while maintaining identical electrical specifications. AC0402FR-0768K1L additionally includes moisture-resistant construction. These parts are suitable for automotive-grade circuit designs requiring enhanced reliability certification.

For Enhanced Power Dissipation:

ERJ-2RKF6812X (Panasonic Electronic Components) provides an upgrade path with 0.1W (1/10W) power rating, supporting applications with higher thermal stress. This part is AEC-Q200 qualified and maintains all core electrical parameters. Selection of this upgrade is appropriate when circuit analysis indicates power dissipation approaching the 0.063W limit of the primary part.

Compliance Considerations:

CRCW040268K1FKTD (Vishay Dale) is not ROHS3 compliant and is REACH affected. This part is not recommended for new designs or applications requiring regulatory compliance with current environmental standards.

All other substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the primary part's regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-6812GLF be used as a direct replacement for RC1005F6812CS?

A: CR0402-FX-6812GLF is electrically equivalent with identical resistance (68.1 kOhms), tolerance (±1%), power rating (0.063W), and package format (0402). Both are ROHS3 compliant and operate across -55°C to 155°C. The primary difference is that CR0402-FX-6812GLF does not include moisture-resistant construction. Direct substitution is valid for applications where moisture resistance is not a circuit requirement.

Q: What is the difference between the main part and ERJ-2RKF6812X?

A: ERJ-2RKF6812X is an upgrade variant with higher power rating (0.1W versus 0.063W) and includes AEC-Q200 automotive qualification. All electrical parameters (resistance, tolerance, temperature coefficient, operating range) remain identical. This part is suitable for applications requiring automotive-grade reliability or circuits with higher power dissipation requirements.

Q: Are all substitute parts available in the same packaging format?

A: No. The primary part RC1005F6812CS is supplied in Tape & Reel (TR) format. Substitute parts are available in both Tape & Reel and Cut Tape & Digi-Reel formats. Packaging format selection depends on assembly equipment compatibility and procurement requirements. Electrical and mechanical specifications remain identical across packaging formats.

Q: Which substitute parts include moisture-resistant construction?

A: RC0402FR-0768K1L (YAGEO) and AC0402FR-0768K1L (YAGEO) include moisture-resistant construction matching the primary part. All other substitute parts do not specify moisture-resistant features. Selection of moisture-resistant variants is necessary for applications exposed to high humidity environments or requiring enhanced reliability in moisture-prone conditions.

Q: Can CRCW040268K1FKTD be used in new product designs?

A: CRCW040268K1FKTD is not ROHS3 compliant and is REACH affected. This part does not meet current environmental regulatory requirements and is not suitable for new product designs. Alternative parts maintaining ROHS3 compliance and REACH unaffected status are available.

Q: What is the height difference between AC0402FR-0768K1L and other 0402 parts?

A: AC0402FR-0768K1L has a maximum seated height of 0.015" (0.37mm), while most other 0402 parts specify 0.016" (0.40mm). This 0.001" difference is within standard PCB design tolerances and does not affect interchangeability for typical surface mount assembly processes.

Q: Are all substitute parts suitable for automotive applications?

A: No. Only ERJ-2RKF6812X (Panasonic), AC0402FR-0768K1L (YAGEO), CRCW040268K1FKED (Vishay Dale), and RMCF0402FT68K1 (Stackpole) carry AEC-Q200 automotive qualification. The primary part RC1005F6812CS and parts CR0402-FX-6812GLF and RC0402FR-0768K1L do not include automotive certification. Selection of AEC-Q200 qualified parts is mandatory for automotive circuit designs.

Q: What inventory levels are available for each substitute part?

A: Inventory availability varies significantly: RMCF0402FT68K1 (280,299 units), CRCW040268K1FKED (229,893 units), ERJ-2RKF6812X (27,688 units), AC0402FR-0768K1L (13,860 units), CRCW040268K1FKTD (10,935 units), RC0402FR-0768K1L (3,300 units), and CR0402-FX-6812GLF (54,103 units). Inventory levels should be verified at time of procurement as stock quantities change continuously.
