RC1608F430CS Equivalent & Substitute Parts Reference

Part Overview

The RC1608F430CS is a 43 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 classified as Active product status with moisture resistant construction and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are necessary when the primary manufacturer part becomes unavailable, when alternative sourcing is required for supply chain optimization, or when design specifications permit the use of functionally identical components from different manufacturers that meet the same electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F430CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 43 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 substitute parts listed meet these mandatory parameters. Substitute parts are categorized by manufacturer and product status (Active or Discontinued at DiGi Electronics). Packaging format variations (Tape & Reel vs. Cut Tape) do not affect electrical or mechanical compatibility but may impact procurement and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Direct Equivalents):

CR0603-FX-43R0ELF (Bourns Inc.), RC0603FR-0743RL (YAGEO), AC0603FR-0743RL (YAGEO), CRCW060343R0FKEA (Vishay Dale), ERJ-3EKF43R0V (Panasonic Electronic Components), and RMCF0603FT43R0 (Stackpole Electronics Inc) are all Active product status components that meet all mandatory electrical and mechanical parameters. These parts are suitable for direct substitution in applications where the RC1608F430CS is specified.

Secondary Substitute (Discontinued Status):

MCR03ERTF43R0 (Rohm Semiconductor) is classified as Discontinued at DiGi Electronics. While this part meets all electrical and mechanical specifications, its discontinued status indicates limited future availability. This part should be considered only when supply from Active status alternatives is constrained.

Compliance Considerations:

All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes and environmental requirements. All parts operate within the -55°C ~ 155°C temperature range with ±100ppm/°C temperature coefficient.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-43R0ELF replace RC1608F430CS in my design?

A: Yes. CR0603-FX-43R0ELF meets all mandatory electrical parameters (43 Ohms ±1%, 0.1W, 0603 package, ±100ppm/°C temperature coefficient, -55°C ~ 155°C operating range) and maintains ROHS3 compliance and MSL 1 rating. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape & Digi-Reel packaging is supplied in shorter tape segments. Both formats contain identical components; the difference is in procurement and assembly logistics, not electrical or mechanical performance.

Q: Why is MCR03ERTF43R0 listed as discontinued?

A: MCR03ERTF43R0 is marked as Discontinued at DiGi Electronics, indicating that this distributor no longer actively stocks this part. However, the component meets all electrical and mechanical specifications for RC1608F430CS substitution. Availability through alternative distributors should be verified before design selection.

Q: Are all substitute parts suitable for automotive applications?

A: AC0603FR-0743RL, CRCW060343R0FKEA, ERJ-3EKF43R0V, and RMCF0603FT43R0 carry AEC-Q200 automotive qualification. The RC1608F430CS (Samsung), CR0603-FX-43R0ELF (Bourns), and RC0603FR-0743RL (YAGEO) do not list AEC-Q200 qualification. Component selection should align with application requirements.

Q: Do all substitute parts have the same physical dimensions?

A: All parts use the 0603 (1608 Metric) package. Most parts specify 0.063" L x 0.031" W (1.60mm x 0.80mm) with 0.022" (0.55mm) maximum seated height. CRCW060343R0FKEA specifies 0.061" L x 0.033" W (1.55mm x 0.85mm) with 0.020" (0.50mm) maximum seated height, and RMCF0603FT43R0 specifies 0.061" L x 0.031" W (1.55mm x 0.80mm). These minor dimensional variations remain within 0603 package tolerance and do not affect PCB layout compatibility.

Q: What inventory levels are available for each substitute?

A: RC0603FR-0743RL (YAGEO) has the highest inventory at 511,838 pieces. ERJ-3EKF43R0V (Panasonic) has 227,290 pieces. AC0603FR-0743RL (YAGEO) has 20,945 pieces. CR0603-FX-43R0ELF (Bourns) has 20,245 pieces. CRCW060343R0FKEA (Vishay Dale) has 19,849 pieces. RMCF0603FT43R0 (Stackpole) has 79,112 pieces. MCR03ERTF43R0 (Rohm) has 2,240 pieces. Inventory levels should be verified with distributors for current availability.
