Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC1608J565CS is based on the following critical parameters that must remain constant or improve:

Mandatory Matching Parameters:

• Resistance value: 5.6 MOhms
• Package / Case: 0603 (1608 Metric)
• Power rating: 0.1W (1/10W)
• Composition: Thick Film
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Variations:

• Tolerance: ±5% (baseline) to ±1% (upgrade)
• Temperature coefficient: ±100ppm/°C to ±200ppm/°C
• Features: Addition of automotive AEC-Q200 qualification or moisture resistance enhancement
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel®

Substitute parts are grouped into direct equivalents (identical specifications) and upgrade options (enhanced tolerance or automotive qualification).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Identical Specifications):

RC0603JR-075M6L (YAGEO) is a direct functional equivalent to RC1608J565CS. Both components share identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. Both maintain RoHS3 compliance and MSL 1 rating. Selection of this part is appropriate for direct replacement in applications where the original Samsung component is unavailable. YAGEO maintains Active product status with significantly higher inventory availability (121,801 pcs vs. 912 pcs).

Upgrade Options (Enhanced Performance):

KTR03EZPF5604 (Rohm Semiconductor) and RMCF0603FT5M60 (Stackpole Electronics Inc) both offer ±1% tolerance improvement over the baseline ±5% specification. Both components carry AEC-Q200 automotive qualification. KTR03EZPF5604 includes high-voltage rating designation. These upgrades are suitable for applications requiring tighter tolerance control or automotive-grade reliability. Both maintain Active product status.

RMCF0603JT5M60 (Stackpole Electronics Inc) maintains the ±5% tolerance baseline while adding AEC-Q200 automotive qualification. This option provides automotive-grade reliability without tolerance upgrade. Active product status with 8,012 pcs inventory.

Discontinued Component:

MCR03ERTJ565 (Rohm Semiconductor) is marked as Discontinued at DiGi Electronics. While specifications remain compatible, this part should not be selected for new designs or long-term production applications.

Frequently Asked Questions (FAQ)

Q: Can RC0603JR-075M6L replace RC1608J565CS in existing designs?

A: Yes. RC0603JR-075M6L is a direct equivalent with identical electrical and mechanical specifications. Both components are 5.6 MOhms ±5% thick film resistors in 0603 package with 0.1W power rating and -55°C to 155°C operating range. Physical dimensions and termination count are identical. No circuit redesign is required.

Q: What is the difference between the ±5% and ±1% tolerance options?

A: Tolerance defines the maximum deviation from the nominal 5.6 MOhms resistance value. ±5% tolerance allows deviation up to ±280 kOhms. ±1% tolerance restricts deviation to ±56 kOhms. Applications requiring precise resistance values or tight circuit performance specifications benefit from ±1% options such as KTR03EZPF5604 or RMCF0603FT5M60.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry standard qualification for passive components. Parts carrying this rating have undergone enhanced reliability testing and are approved for automotive applications. KTR03EZPF5604, RMCF0603FT5M60, and RMCF0603JT5M60 all carry AEC-Q200 qualification, making them suitable for automotive circuit designs.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Most substitute parts are supplied in Tape & Reel (TR) format. MCR03ERTJ565 is supplied in Cut Tape (CT) & Digi-Reel® format. Verify packaging requirements with your procurement specifications before component selection.

Q: Why is MCR03ERTJ565 marked as discontinued?

A: MCR03ERTJ565 is discontinued at DiGi Electronics, indicating this distributor no longer stocks or supports this part. This status does not reflect manufacturer discontinuation but rather distributor inventory decisions. For new designs or production quantities, select from Active status alternatives.

Q: Do all substitute parts maintain RoHS3 and MSL 1 compliance?

A: Yes. All listed substitute parts maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original RC1608J565CS specifications.

Q: What is the temperature coefficient difference between ±100ppm/°C and ±200ppm/°C?

A: Temperature coefficient defines resistance change per degree Celsius. ±100ppm/°C produces smaller resistance variation across temperature extremes compared to ±200ppm/°C. RC1608J565CS and RC0603JR-075M6L specify ±100ppm/°C. MCR03ERTJ565, RMCF0603FT5M60, and RMCF0603JT5M60 specify ±200ppm/°C. Applications operating across wide temperature ranges may require the tighter ±100ppm/°C specification.
