Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F270CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (27 Ohms), tolerance (±1%), power rating (0.1W), and temperature coefficient (±100ppm/°C) must be identical.

Mechanical Compatibility: Package type (0603/1608 Metric), physical dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm), and number of terminations (2) must match or be within acceptable PCB footprint tolerances.

Compliance & Environmental: RoHS3 compliance and MSL 1 rating are mandatory. Operating temperature range (-55°C ~ 155°C) must be maintained.

Composition & Features: Thick film construction is required. Moisture resistance and automotive AEC-Q200 certification are optional enhancements that do not prevent substitution.

Substitute parts are categorized as Direct (identical specifications and packaging), Upgrade (enhanced features such as AEC-Q200 automotive qualification), or Similar (minor dimensional variations within acceptable tolerances).

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Equivalent Performance):

CR0603-FX-27R0ELF (Bourns Inc.) and RC0603FR-0727RL (YAGEO) are direct functional equivalents to the RC1608F270CS. Both maintain identical electrical specifications, 0603 package dimensions, and moisture-resistant thick film construction. These parts are suitable for applications where the original Samsung component is unavailable or where supply chain diversification is required.

Upgrade Substitutes (Enhanced Compliance):

KTR03EZPF27R0 (Rohm Semiconductor), AC0603FR-0727RL (YAGEO), CRCW060327R0FKEA (Vishay Dale), ERJ-3EKF27R0V (Panasonic), and RMCF0603FT27R0 (Stackpole Electronics) incorporate Automotive AEC-Q200 qualification in addition to standard specifications. These components are suitable for applications requiring automotive-grade reliability and are backward-compatible with non-automotive designs. Selection of AEC-Q200 qualified parts introduces no performance penalty and provides enhanced qualification documentation for regulated industries.

Packaging Considerations:

The RC1608F270CS is supplied in Tape & Reel (TR) packaging. CR0603-FX-27R0ELF and RC0603FR-0727RL are supplied in Cut Tape (CT) & Digi-Reel® format. All remaining substitutes are supplied in Tape & Reel format. Packaging format selection depends on assembly equipment compatibility and procurement volume requirements.

Compliance Status:

All listed parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with modern manufacturing processes and long-term storage without baking requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC0603FR-0727RL for RC1608F270CS in my design?

A: Yes. RC0603FR-0727RL (YAGEO) is a direct equivalent with identical resistance (27 Ohms), tolerance (±1%), power rating (0.1W), package (0603), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Both are RoHS3 compliant with MSL 1 rating. The only difference is packaging format (Cut Tape & Digi-Reel vs. Tape & Reel) and manufacturer, which does not affect electrical performance.

Q: What is the difference between standard and AEC-Q200 qualified substitutes?

A: AEC-Q200 qualification (KTR03EZPF27R0, AC0603FR-0727RL, CRCW060327R0FKEA, ERJ-3EKF27R0V, RMCF0603FT27R0) indicates the component meets automotive industry reliability and testing standards. These parts are electrically and mechanically identical to non-automotive versions but include additional qualification documentation. AEC-Q200 parts are suitable for both automotive and non-automotive applications.

Q: Are there dimensional differences between substitute parts?

A: Most substitutes maintain the standard 0603 package dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm). CRCW060327R0FKEA and RMCF0603FT27R0 have minor dimensional variations (length 0.061" / 1.55mm and width 0.033" / 0.85mm for CRCW; length 0.061" / 1.55mm for RMCF). These variations are within acceptable PCB footprint tolerances for 0603 packages and do not require design modification.

Q: Which substitute offers the best availability?

A: RC0603FR-0727RL (YAGEO) and RMCF0603FT27R0 (Stackpole Electronics) show the highest inventory levels (508,998 and 341,154 units respectively). CR0603-FX-27R0ELF (Bourns) also maintains substantial stock (348,598 units). Availability should be confirmed with your component supplier for current project timelines.

Q: Can I use these substitutes in high-temperature applications?

A: Yes. All listed parts maintain the operating temperature range of -55°C ~ 155°C with ±100ppm/°C temperature coefficient. This specification is identical across all substitutes and the original RC1608F270CS, ensuring consistent performance in temperature-sensitive applications.

Q: Do I need to re-qualify my design if I switch to an AEC-Q200 substitute?

A: No re-qualification is required. AEC-Q200 parts are backward-compatible with designs specified for standard 27 Ohm ±1% 0603 resistors. The enhanced qualification of AEC-Q200 components does not introduce incompatibility with existing designs.
