RC1608F1R2CS Equivalent & Substitute Parts Reference

Part Overview

The RC1608F1R2CS is a 1.2 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0603 (1608 Metric) package format. This component is rated for 0.1W (1/10W) power dissipation with moisture resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching electrical specifications, mechanical dimensions, and environmental compliance requirements. Alternative sources provide identical or superior performance characteristics while maintaining compatibility with the original design specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1608F1R2CS are qualified based on the following critical parameters:

Electrical Specifications: Resistance value of 1.2 Ohms, tolerance of ±1%, and power rating of 0.1W (1/10W) must be identical across all substitutes.

Package Compatibility: All substitute parts must use the 0603 (1608 Metric) package format with identical or equivalent physical dimensions and two terminations to ensure PCB footprint compatibility.

Environmental Compliance: All substitutes maintain ROHS3 compliance, MSL 1 rating, and operating temperature range of -55°C to 155°C.

Composition: Thick film construction is maintained across all qualified substitutes.

The three substitute parts listed below meet all substitution criteria. Two substitutes (ERJ-3RQF1R2V and KTR03EZPF1R20) include additional automotive AEC-Q200 qualification, while RMCF0603FT1R20 also carries AEC-Q200 certification. These enhancements do not restrict substitution but indicate expanded application suitability.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are direct functional equivalents to the RC1608F1R2CS and are suitable for component replacement in applications requiring 1.2 Ohm ±1% thick film resistors in 0603 package format.

ERJ-3RQF1R2V (Panasonic Electronic Components): This substitute carries AEC-Q200 automotive qualification and current sense features. Temperature coefficient of ±200ppm/°C provides improved stability compared to the original part. Suitable for automotive and industrial applications requiring enhanced reliability certification.

KTR03EZPF1R20 (Rohm Semiconductor): This substitute includes AEC-Q200 automotive qualification with high voltage capability. Temperature coefficient of ±200ppm/°C matches the Panasonic alternative. Appropriate for applications requiring automotive-grade components with extended voltage performance.

RMCF0603FT1R20 (Stackpole Electronics Inc): This substitute carries AEC-Q200 automotive qualification with standard thick film construction. Physical dimensions of 0.061" L x 0.031" W (1.55mm x 0.80mm) remain within acceptable tolerance for 0603 package footprints. Temperature coefficient of ±200ppm/°C provides improved thermal stability.

All substitutes maintain ROHS3 compliance, MSL 1 rating, and identical operating temperature range. Selection among substitutes depends on application requirements, supply chain availability, and specific automotive or industrial certification needs.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3RQF1R2V replace RC1608F1R2CS in any application?

A: Yes. Both parts share identical electrical specifications (1.2 Ohms ±1%, 0.1W), package format (0603), and environmental ratings (ROHS3, MSL 1, -55°C to 155°C). The ERJ-3RQF1R2V includes additional AEC-Q200 automotive qualification, which does not restrict its use in non-automotive applications.

Q: What is the difference in temperature coefficient between the main part and substitutes?

A: The RC1608F1R2CS has a temperature coefficient of ±300ppm/°C. All three substitutes (ERJ-3RQF1R2V, KTR03EZPF1R20, RMCF0603FT1R20) have a temperature coefficient of ±200ppm/°C, indicating improved thermal stability across the operating range.

Q: Are there physical dimension differences between substitutes?

A: The RMCF0603FT1R20 has a length of 0.061" (1.55mm) compared to 0.063" (1.60mm) for the other parts. All dimensions remain within standard 0603 package tolerances and are compatible with existing PCB footprints.

Q: Do all substitutes meet the same compliance requirements?

A: Yes. All substitute parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and operate across -55°C to 155°C. All are packaged in Tape & Reel format.

Q: Which substitute should be selected for automotive applications?

A: All three substitutes carry AEC-Q200 automotive qualification. Selection depends on specific application requirements: ERJ-3RQF1R2V for current sense applications, KTR03EZPF1R20 for high voltage requirements, or RMCF0603FT1R20 for standard automotive use.

Q: Is the 0603 package footprint identical across all parts?

A: Yes. All parts use the 0603 (1608 Metric) package with two terminations. Physical dimensions are within standard package tolerances, ensuring PCB footprint compatibility.
