Mandatory Matching Parameters:

• Resistance value: 35.7 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)
• RoHS compliance: ROHS3 Compliant

All identified substitute parts meet these mandatory parameters. Substitute parts are further categorized by additional features:

Direct Equivalent: RC0603FR-0735R7L (YAGEO) matches all parameters with identical moisture-resistant construction.

Similar Parts with Enhanced Features: CRCW060335R7FKEA (Vishay Dale), ERJ-3EKF35R7V (Panasonic Electronic Components), and RMCF0603FT35R7 (Stackpole Electronics Inc) include Automotive AEC-Q200 qualification in addition to all mandatory parameters, providing enhanced reliability for automotive applications.

Parameter Comparison

Engineering Selection Recommendations

For General-Purpose Applications: RC0603FR-0735R7L (YAGEO) is the direct equivalent substitute. This part maintains identical electrical and mechanical specifications with moisture-resistant construction matching the original Samsung component. Both parts are Active status with ROHS3 compliance and unlimited moisture sensitivity rating.

For Automotive Applications: CRCW060335R7FKEA (Vishay Dale), ERJ-3EKF35R7V (Panasonic Electronic Components), or RMCF0603FT35R7 (Stackpole Electronics Inc) are suitable substitutes when Automotive AEC-Q200 qualification is required. All three parts maintain the mandatory electrical parameters while providing enhanced automotive-grade reliability certification. Selection among these three should be based on availability and procurement requirements, as all three meet identical electrical and mechanical specifications with AEC-Q200 qualification.

All substitute parts are Active status and ROHS3 compliant, ensuring regulatory compliance and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-0735R7L be used as a direct replacement for RC1608F35R7CS?

A: Yes. RC0603FR-0735R7L is a direct equivalent substitute. Both parts share identical resistance (35.7 Ohms), tolerance (±1%), power rating (0.1W), package (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and moisture sensitivity level (1). Both are ROHS3 compliant and Active status.

Q: What is the difference between the Samsung part and the Vishay, Panasonic, and Stackpole alternatives?

A: The primary difference is the addition of Automotive AEC-Q200 qualification on the Vishay Dale CRCW060335R7FKEA, Panasonic ERJ-3EKF35R7V, and Stackpole RMCF0603FT35R7 parts. All other electrical and mechanical parameters remain identical. These three parts are suitable for automotive applications requiring AEC-Q200 certification.

Q: Are there any dimensional differences between these substitute parts?

A: Minor dimensional variations exist within acceptable tolerances. The Samsung RC1608F35R7CS and Panasonic ERJ-3EKF35R7V measure 0.063" L x 0.031" W (1.60mm x 0.80mm) with 0.022" (0.55mm) maximum seated height. The Vishay Dale CRCW060335R7FKEA and Stackpole RMCF0603FT35R7 measure 0.061" L x 0.033" W (1.55mm x 0.85mm) and 0.061" L x 0.031" W (1.55mm x 0.80mm) respectively, with 0.020" (0.50mm) and 0.022" (0.55mm) maximum seated heights. These variations are within standard 0603 package tolerances and do not affect PCB layout compatibility.

Q: Which substitute part has the highest inventory availability?

A: ERJ-3EKF35R7V (Panasonic Electronic Components) has the highest inventory with 599,837 pieces in stock, followed by RC0603FR-0735R7L (YAGEO) with 23,828 pieces, CRCW060335R7FKEA (Vishay Dale) with 3,237 pieces, and RMCF0603FT35R7 (Stackpole Electronics Inc) with 1,797 pieces.

Q: Can these parts be used interchangeably in the same PCB assembly?

A: Yes. All substitute parts are qualified for the same 0603 (1608 Metric) package footprint and share identical electrical specifications. PCB layout and assembly processes require no modification when substituting between these parts.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts, including RC0603FR-0735R7L, CRCW060335R7FKEA, ERJ-3EKF35R7V, and RMCF0603FT35R7, are ROHS3 compliant with REACH Unaffected status.
