RC1608F6040CS Equivalent & Substitute Parts Reference

Part Overview

The RC1608F6040CS is a 604 Ohms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0603 (1608 Metric) package format with 0.1W power rating. This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1). The part is suitable for general industrial and consumer applications requiring standard tolerance resistive elements.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when supply chain optimization is required, or when design flexibility permits component sourcing from multiple qualified manufacturers. All substitute parts listed maintain identical electrical specifications and mechanical compatibility within the 0603 package standard.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F6040CS is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Resistance value: 604 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 to 155°C
• Termination count: 2
• Moisture sensitivity level: 1 (Unlimited)

All substitute parts listed meet these mandatory parameters. Physical dimensions may vary within acceptable tolerances for the 0603 package standard. Compliance certifications (RoHS, REACH, AEC-Q200) are noted but do not restrict substitution eligibility; they indicate additional qualifications available in specific part variants.

Engineering Selection Recommendations

For Standard Industrial Applications (Non-Automotive): Select from CR0603-FX-6040ELF (Bourns), RC0603FR-07604RL (YAGEO), or RMCF0603FT604R (Stackpole). These parts maintain full RoHS3 compliance and provide adequate inventory availability. The Stackpole RMCF0603FT604R offers the highest inventory level (464,703 pcs) for applications with extended supply chain requirements.

For Automotive Applications (AEC-Q200 Required): Select from AC0603FR-07604RL (YAGEO), CRCW0603604RFKEA (Vishay Dale), ERJ-3EKF6040V (Panasonic), or RMCF0603FG604R (Stackpole). All four parts carry AEC-Q200 qualification and ROHS3 compliance. The ERJ-3EKF6040V provides the highest inventory availability (119,096 pcs) among AEC-Q200 qualified options.

For Legacy or Unrestricted Applications: CRCW0603604RFKTA (Vishay Dale) is available as an alternative when RoHS3 compliance is not a design requirement. This part carries AEC-Q200 qualification but is RoHS non-compliant and REACH affected.

Inventory Considerations: When supply continuity is critical, prioritize RMCF0603FT604R (464,703 pcs), ERJ-3EKF6040V (119,096 pcs), or CRCW0603604RFKEA (46,513 pcs) based on application requirements.

Frequently Asked Questions (FAQ)

Q: Can RC1608F6040CS be directly replaced with CR0603-FX-6040ELF?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (604 Ohms), tolerance (±1%), power rating (0.1W), package (0603), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). Both are RoHS3 compliant with MSL 1 rating.

Q: What is the difference between RMCF0603FG604R and RMCF0603FT604R?

A: Both Stackpole parts are electrically identical (604 Ohms ±1%, 0.1W, 0603 package, AEC-Q200 qualified, ROHS3 compliant). The primary difference is inventory availability: RMCF0603FT604R has significantly higher stock (464,703 pcs vs. 670 pcs). Physical dimensions are identical.

Q: Are AEC-Q200 qualified parts required for non-automotive use?

A: No. AEC-Q200 qualification is an additional certification for automotive applications. Non-automotive designs can use any electrically equivalent part. However, AEC-Q200 qualified parts are fully compatible as substitutes in non-automotive applications.

Q: Can CRCW0603604RFKTA be used in new designs?

A: CRCW0603604RFKTA is electrically equivalent and AEC-Q200 qualified but is RoHS non-compliant and REACH affected. It is suitable only for applications where RoHS3 compliance is not required. For new designs, CRCW0603604RFKEA (RoHS3 compliant variant) is recommended.

Q: What does MSL 1 (Unlimited) mean for these resistors?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. All listed parts have MSL 1 rating, meaning they can be stored indefinitely under normal conditions without special moisture control procedures.

Q: Are physical dimension variations between manufacturers significant?

A: Physical dimensions vary slightly within the 0603 package standard (length 0.061" to 0.063", width 0.031" to 0.033", height 0.020" to 0.022"). These variations are within acceptable tolerances for standard PCB footprints and do not affect electrical performance or mechanical fit.

Q: Which substitute offers the best supply chain security?

A: RMCF0603FT604R (Stackpole) with 464,703 pcs inventory provides the highest availability. ERJ-3EKF6040V (Panasonic) with 119,096 pcs is the second option. For AEC-Q200 non-critical applications, CR0603-FX-6040ELF (Bourns) with 24,951 pcs is also well-stocked.
