Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F6194CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (6.19 MOhms), tolerance (±1%), power rating (0.125W), and temperature coefficient (±100ppm/°C) must be identical. These parameters ensure functional interchangeability in circuit applications.

Mechanical Parameters: Package designation (0805/2012 Metric), physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm), and number of terminations (2) must match to ensure PCB footprint compatibility and assembly process compatibility.

Compliance Parameters: RoHS3 compliance, MSL rating (1), and REACH unaffected status must be maintained to satisfy regulatory and environmental requirements.

Material Composition: Thick film construction is required for consistency in thermal and frequency response characteristics.

The substitute part RC0805FR-076M19L from YAGEO meets all these criteria and is therefore classified as an equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the RCS2012F6194CS and RC0805FR-076M19L are active production components with full regulatory compliance. Selection between these parts should be based on:

Availability: The RC0805FR-076M19L from YAGEO offers significantly higher inventory availability (15,505 units) compared to the RCS2012F6194CS (830 units), making it suitable for high-volume production requirements.

Compliance Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for electronic component procurement.

Physical Clearance: The RC0805FR-076M19L has a maximum seated height of 0.024" (0.60mm) compared to 0.026" (0.66mm) for the RCS2012F6194CS. This minor dimensional difference does not affect standard PCB assembly processes but may be relevant in space-constrained applications.

Supply Chain Continuity: Either part may be selected as the primary component with the other designated as the approved substitute to ensure uninterrupted supply chain access.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-076M19L be used as a direct replacement for RCS2012F6194CS in existing designs?

A: Yes. Both parts share identical electrical specifications (6.19 MOhms ±1%, 0.125W, ±100ppm/°C), mechanical package dimensions (0805/2012 Metric), and compliance certifications (ROHS3, MSL 1). PCB footprints and assembly processes require no modification.

Q: What is the significance of the height difference between these parts?

A: The RCS2012F6194CS has a maximum seated height of 0.66mm while the RC0805FR-076M19L measures 0.60mm. This 0.06mm difference is within standard PCB assembly tolerances and does not affect component placement or soldering processes in typical applications.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both the RCS2012F6194CS and RC0805FR-076M19L operate across the identical temperature range of -55°C to 155°C with a temperature coefficient of ±100ppm/°C, making them suitable for industrial and automotive applications within these specifications.

Q: What does MSL 1 (Unlimited) moisture sensitivity rating mean?

A: MSL 1 indicates the lowest moisture sensitivity level. Both parts can be stored indefinitely without moisture bake-out requirements prior to soldering, simplifying inventory management and reducing production constraints.

Q: Are there any differences in the anti-sulfur or moisture-resistant properties?

A: The RCS2012F6194CS is specified with anti-sulfur and moisture-resistant features. The RC0805FR-076M19L is specified with moisture-resistant features. Both maintain MSL 1 rating and ROHS3 compliance. Application-specific requirements for sulfur resistance should be evaluated based on environmental exposure conditions.

Q: Can these parts be mixed within the same production batch?

A: Yes. Both parts are functionally equivalent with identical electrical and mechanical specifications. Mixed sourcing is permissible provided component traceability and supplier documentation are maintained for quality assurance records.
