RC1608F6190CS Equivalent & Substitute Parts Reference

Part Overview

The RC1608F6190CS is a 619 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 with moisture-resistant construction and unlimited moisture sensitivity level (MSL 1). The part is ROHS3 compliant and REACH unaffected, suitable for general industrial and consumer electronics applications requiring precision resistive elements in compact surface-mount form factors.

Equivalent and substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization requires alternative sourcing, or when design specifications permit functional alternatives from qualified manufacturers meeting identical electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F6190CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 619 Ohms (exact match required)
• Tolerance: ±1% (precision grade must match)
• Power rating: 0.1W / 1/10W (thermal capacity must match)
• Package / Case: 0603 (1608 Metric) (physical footprint must match)
• Composition: Thick Film (manufacturing technology must match)
• Temperature coefficient: ±100ppm/°C (stability specification must match)
• Operating temperature range: -55°C ~ 155°C (environmental limits must match)
• Number of terminations: 2 (connection configuration must match)
• RoHS Status: ROHS3 Compliant (regulatory compliance must match)
• Moisture Sensitivity Level: 1 (handling requirements must match)

All substitute parts listed below meet these mandatory parameters. Substitutes are grouped by relationship type: Direct Manufacturer Substitutes (functionally identical, different manufacturer), Upgrade Substitutes (enhanced features or certifications), and Similar Substitutes (additional qualifications such as automotive AEC-Q200 rating).

Parameter Comparison

Engineering Selection Recommendations

Direct Manufacturer Substitutes (Functionally Equivalent):

CR0603-FX-6190ELF (Bourns Inc.) and RC0603FR-07619RL (YAGEO) are direct functional equivalents to the RC1608F6190CS. Both parts maintain Active product status, identical electrical specifications, and moisture-resistant construction. These substitutes are suitable for direct replacement in applications where Samsung Electro-Mechanics sourcing is unavailable. Bourns CR0603-FX-6190ELF offers 56,902 units in stock inventory. YAGEO RC0603FR-07619RL provides 40,601 units in stock inventory.

Upgrade Substitute with Enhanced Qualification:

CRCW0603619RFKEA (Vishay Dale), ERJ-3EKF6190V (Panasonic Electronic Components), and RMCF0603FT619R (Stackpole Electronics Inc) are functionally equivalent substitutes with additional Automotive AEC-Q200 qualification. These parts meet all mandatory electrical and mechanical parameters while providing enhanced reliability certification for automotive-grade applications. All three maintain Active product status. These substitutes are appropriate for applications requiring automotive-grade component qualification or when enhanced reliability documentation is required. Vishay Dale CRCW0603619RFKEA provides 32,007 units in stock. Panasonic ERJ-3EKF6190V provides 78,828 units in stock. Stackpole RMCF0603FT619R provides 35,617 units in stock.

Discontinued Substitute (Limited Availability):

MCR03ERTF6190 (Rohm Semiconductor) is functionally equivalent but marked as Discontinued at DiGi Electronics. This part meets all mandatory electrical and mechanical parameters but has limited future availability. Selection of this substitute is not recommended for new designs or long-term production requirements. Current inventory shows 1,242 units available.

All listed substitutes are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications as the primary part.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-6190ELF (Bourns) be used as a direct replacement for RC1608F6190CS (Samsung)?

A: Yes. CR0603-FX-6190ELF meets all mandatory electrical and mechanical parameters: 619 Ohms ±1%, 0.1W power rating, 0603 package, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and ROHS3 compliance. The part is functionally equivalent and suitable for direct PCB substitution.

Q: What is the difference between the standard substitutes and the automotive-qualified versions?

A: CRCW0603619RFKEA (Vishay Dale), ERJ-3EKF6190V (Panasonic), and RMCF0603FT619R (Stackpole) carry Automotive AEC-Q200 qualification in addition to meeting all base electrical and mechanical specifications. This qualification indicates enhanced reliability testing and documentation suitable for automotive applications. The RC1608F6190CS, CR0603-FX-6190ELF, and RC0603FR-07619RL do not carry this automotive qualification. Selection depends on application requirements.

Q: Are there physical dimension differences between substitute parts?

A: Minor physical dimension variations exist within the 0603 package specification. CRCW0603619RFKEA (Vishay Dale) and RMCF0603FT619R (Stackpole) have slightly different length and height specifications (1.55mm x 0.85mm and 1.55mm x 0.80mm respectively) compared to the standard 1.60mm x 0.80mm specification. These variations remain within 0603 package tolerance and do not affect PCB footprint compatibility. Height-seated maximum specifications range from 0.020" to 0.022" across all parts, all within acceptable reflow and assembly parameters.

Q: Why is MCR03ERTF6190 (Rohm) listed as discontinued?

A: MCR03ERTF6190 is marked as Discontinued at DiGi Electronics, indicating this distributor no longer actively stocks or supports this part. While the part meets all electrical and mechanical specifications, future availability cannot be assured. This part is not recommended for new designs or applications requiring long-term supply continuity.

Q: What packaging formats are available for these substitutes?

A: CR0603-FX-6190ELF (Bourns), RC0603FR-07619RL (YAGEO), CRCW0603619RFKEA (Vishay Dale), and ERJ-3EKF6190V (Panasonic) are supplied in Tape & Reel (TR) format. MCR03ERTF6190 (Rohm) is supplied in Cut Tape (CT) & Digi-Reel® format. RMCF0603FT619R (Stackpole) is supplied in Tape & Reel (TR) format. All packaging formats are suitable for automated assembly processes.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited) and REACH unaffected status, matching the primary RC1608F6190CS specification.
