Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F6494CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 6.49 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: MSL 1

Substitute Classification:

Direct Equivalent: RC0805FR-076M49L (YAGEO) — Identical electrical and environmental specifications with equivalent moisture resistance and thermal performance.

Similar Substitute: CRCW08056M49FKEA (Vishay Dale) — Meets all core electrical parameters with additional automotive AEC-Q200 qualification. Physical height differs (0.020" vs. 0.026" seated maximum), which may affect PCB layout in space-constrained applications.

Parameter Comparison

Engineering Selection Recommendations

RC0805FR-076M49L (YAGEO) — Recommended Direct Substitute

This part provides direct functional equivalence to the RC2012F6494CS. All electrical parameters, environmental ratings, and compliance certifications are identical. The YAGEO RC0805FR-076M49L carries ROHS3 compliance and MSL 1 rating, matching the original specification. Higher inventory availability (15021 pieces) supports procurement continuity. Selection of this substitute requires no design modifications or PCB layout adjustments.

CRCW08056M49FKEA (Vishay Dale) — Qualified Substitute for Automotive Applications

This part meets all core electrical and environmental specifications with the addition of AEC-Q200 automotive qualification. The lower seated height (0.020" vs. 0.026") may provide advantages in space-constrained PCB layouts but requires verification against specific board design constraints. This substitute is appropriate for applications requiring automotive-grade reliability certification. ROHS3 compliance and MSL 1 rating are maintained.

Selection Criteria:

• Standard applications: RC0805FR-076M49L offers direct equivalence with superior inventory availability.
• Automotive or high-reliability applications: CRCW08056M49FKEA provides additional AEC-Q200 qualification.
• Space-critical designs: CRCW08056M49FKEA's reduced height may be beneficial; verify PCB layout compatibility.
• Supply chain flexibility: All three parts maintain identical electrical performance and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-076M49L be used as a direct replacement for RC2012F6494CS?

A: Yes. The RC0805FR-076M49L is a direct equivalent. All electrical parameters (6.49 MOhms, ±1%, 0.125W), package specifications (0805), environmental ratings (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL 1) are identical. No design modifications are required.

Q: What is the difference between the YAGEO and Vishay Dale substitutes?

A: Both parts meet the core electrical and environmental specifications. The primary difference is that CRCW08056M49FKEA includes AEC-Q200 automotive qualification, which is not specified for the YAGEO part. Additionally, CRCW08056M49FKEA has a lower seated height (0.020" vs. 0.024"), which may affect PCB layout in space-constrained applications.

Q: Does the height difference between substitutes affect PCB compatibility?

A: The height difference is minimal (0.026" original, 0.024" YAGEO, 0.020" Vishay Dale). For most applications, this variation is within standard PCB assembly tolerances. However, designs with tight vertical clearance requirements should verify compatibility with specific board constraints.

Q: Are all three parts ROHS3 compliant?

A: Yes. RC2012F6494CS, RC0805FR-076M49L, and CRCW08056M49FKEA are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Which substitute should I select for automotive applications?

A: CRCW08056M49FKEA is qualified to AEC-Q200 automotive standards. If automotive qualification is a design requirement, this part is the appropriate selection. For non-automotive applications, RC0805FR-076M49L provides direct equivalence.

Q: What is the packaging difference between substitutes?

A: RC2012F6494CS and RC0805FR-076M49L are supplied in Tape & Reel (TR) format. CRCW08056M49FKEA is available in Cut Tape (CT) and Digi-Reel® formats. Verify packaging compatibility with your procurement and assembly processes.

Q: Can I mix these parts in the same production run?

A: All three parts meet identical electrical specifications and environmental ratings. Mixing is permissible from an electrical standpoint. However, verify that your assembly process and quality control procedures accommodate multiple part numbers with the same functional specification.
