MCS04020C6819FE000 Equivalent & Substitute Parts

Part Overview

The MCS04020C6819FE000 is a 68.1 Ohm ±1% thin film chip resistor in 0402 (1005 Metric) package rated at 1/16W (0.063W) with anti-sulfur coating. Manufactured by Vishay Beyschlag/Draloric/BC Components, this component is active and RoHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the 0402 package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory parameters:

• Resistance value: 68.1 Ohms (exact match required)
• Package: 0402 (1005 Metric) form factor
• Power rating: 0.063W minimum
• Composition: Thin film construction
• Operating temperature range: -55°C to 155°C minimum
• RoHS3 compliance

Tolerance and temperature coefficient may vary within acceptable engineering margins. Parts are grouped as direct equivalents (matching ±1% tolerance) or upgrades (tighter tolerance specifications).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (RT0402FRE0768R1L): YAGEO RT0402FRE0768R1L maintains identical electrical specifications including ±1% tolerance and ±50ppm/°C temperature coefficient. All compliance certifications match the main part. This substitute is suitable for direct replacement in applications where the original specification tolerance is acceptable.

Upgrade Options (CPF0402B68R1E1 and RN73C1E68R1BTDF): Both TE Connectivity parts offer tighter tolerance (±0.1%) and improved temperature stability. CPF0402B68R1E1 provides ±25ppm/°C performance, while RN73C1E68R1BTDF delivers ±10ppm/°C. These upgrades are applicable in precision circuits requiring enhanced accuracy. Both maintain RoHS3 compliance and MSL 1 rating. Height specifications are marginally reduced (0.014" vs 0.015"), which is compatible with standard 0402 PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can RT0402FRE0768R1L be used as a direct replacement for MCS04020C6819FE000?

A: Yes. Both parts share identical resistance (68.1 Ohms), tolerance (±1%), power rating (0.063W), package (0402), and temperature range (-55°C to 155°C). Electrical performance is equivalent.

Q: What is the difference between direct equivalents and upgrade parts?

A: Direct equivalents match all electrical specifications of the original part. Upgrade parts offer improved tolerance (±0.1% vs ±1%) and lower temperature coefficient, providing higher precision at the cost of potentially different availability or pricing.

Q: Are the upgrade parts (CPF0402B68R1E1 and RN73C1E68R1BTDF) physically compatible?

A: Yes. Both upgrade parts use the same 0402 package with maximum height of 0.014" (0.35mm), which is within standard PCB design tolerances for 0402 components. The 0.001" height reduction from the main part does not affect mechanical compatibility.

Q: Do all substitute parts meet the same compliance requirements?

A: All listed substitutes are RoHS3 compliant and carry MSL 1 rating. REACH status varies by manufacturer but does not affect functional substitution eligibility.

Q: Which substitute should be selected for cost optimization?

A: RT0402FRE0768R1L provides equivalent performance at potentially lower cost due to YAGEO's market positioning. Upgrade parts command premium pricing due to tighter tolerance specifications.
