RC1608F82R5CS Equivalent & Substitute Parts Reference

Part Overview

The RC1608F82R5CS is a 82.5 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.1W (1/10W) power dissipation in a 0603 (1608 Metric) surface mount package. This component is actively produced and widely used in general-purpose electronic applications requiring precision resistive elements with moisture resistance.

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to supply constraints, manufacturing discontinuation, or specific application certifications such as automotive qualification (AEC-Q200).

Composition	Thick Film	Determines electrical characteristics and temperature stability
Temperature Coefficient	±100ppm/°C	Defines resistance drift over operating temperature range
Operating Temperature Range	-55°C ~ 155°C	Must support application environment
Moisture Sensitivity Level (MSL)	1 (Unlimited)	Indicates handling and storage requirements
RoHS Status	ROHS3 Compliant	Regulatory compliance requirement

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

Resistance value: 82.5 Ohms
Tolerance: ±1%
Power rating: 0.1W (1/10W)
Package: 0603 (1608 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
Moisture Sensitivity Level: 1 (Unlimited)

Compliance Considerations:

RoHS3 compliance is required for the primary substitute group
AEC-Q200 automotive qualification is an additional feature available in certain substitute options but is not required for general-purpose substitution
REACH compliance status is noted but does not restrict substitution eligibility

All identified substitutes meet the mandatory electrical and mechanical parameters. Differences in physical dimensions (length, width, height) within the 0603 package specification do not affect functional substitution.

Engineering Selection Recommendations

Primary Substitutes (Direct Equivalents):

CR0603-FX-82R5ELF (Bourns Inc.) and RC0603FR-0782R5L (YAGEO) are direct functional equivalents to the RC1608F82R5CS. Both components match all mandatory electrical and mechanical parameters, maintain RoHS3 compliance, and are actively produced. Selection between these options is based on supply availability and packaging preference (Tape & Reel format).

Automotive-Qualified Alternatives:

CRCW060382R5FKEA (Vishay Dale), ERJ-3EKF82R5V (Panasonic Electronic Components), and RMCF0603FT82R5 (Stackpole Electronics Inc) are functionally equivalent substitutes with additional AEC-Q200 automotive qualification. These components are suitable for applications requiring automotive-grade reliability and are recommended when design specifications mandate AEC-Q200 certification.

Compliance Note:

CRCW060382R5FKTA (Vishay Dale) is listed as a similar part but carries RoHS non-compliant and REACH Affected status. This component is not recommended for new designs requiring RoHS3 compliance.

Inventory and Availability:

RC0603FR-0782R5L (YAGEO) maintains the highest inventory level (729,776 pcs), followed by ERJ-3EKF82R5V (Panasonic, 208,482 pcs) and RMCF0603FT82R5 (Stackpole, 148,499 pcs). Selection may be influenced by supply chain requirements and lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC1608F82R5CS with any of the listed alternatives without circuit redesign?

A: Yes. All listed substitutes (except CRCW060382R5FKTA) match the mandatory electrical parameters: 82.5 Ohms ±1%, 0.1W power rating, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. No circuit redesign is required for functional substitution.

Q: What is the difference between "Direct" and "Similar" substitute classifications?

A: Direct substitutes (CR0603-FX-82R5ELF and RC0603FR-0782R5L) are functionally identical to the main part with no additional certifications. Similar substitutes include AEC-Q200 automotive qualification (CRCW060382R5FKEA, ERJ-3EKF82R5V, RMCF0603FT82R5), which adds reliability assurance for automotive applications but does not alter core electrical performance.

Q: Does package format (Tape & Reel vs. Cut Tape) affect electrical performance?

A: No. Package format affects only handling, storage, and assembly logistics. Electrical and thermal characteristics remain identical regardless of packaging format.

Q: Why is CRCW060382R5FKTA not recommended despite matching electrical specifications?

A: CRCW060382R5FKTA is RoHS non-compliant and REACH Affected. For applications requiring regulatory compliance with RoHS3 standards, this component is not suitable. Use CRCW060382R5FKEA instead, which is the RoHS3-compliant variant from the same manufacturer.

Q: Should I select an AEC-Q200 qualified substitute if my application is not automotive?

A: AEC-Q200 qualification is not required for non-automotive applications. Selection of automotive-qualified alternatives (ERJ-3EKF82R5V, RMCF0603FT82R5, CRCW060382R5FKEA) is optional and based on supply availability or internal design standards. All substitutes meet identical electrical performance requirements.

Q: Are there any dimensional differences between substitutes that affect PCB layout?

A: All substitutes conform to the 0603 (1608 Metric) package specification. Minor variations in length (0.061" to 0.063"), width (0.031" to 0.033"), and height (0.020" to 0.022") fall within standard 0603 tolerances and do not affect PCB footprint compatibility or assembly processes.

Q: What is MSL 1 (Unlimited) and why is it important?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. The part can be stored indefinitely without special humidity control and does not require baking before reflow soldering. All listed substitutes share this MSL rating.

Q: Can I mix different substitute manufacturers in the same production batch?

A: Yes. All substitutes meet identical electrical specifications and package requirements. Mixed sourcing is permissible from a functional standpoint, though single-source procurement may be preferred for supply chain consistency and traceability.
