RC1608J623CS Equivalent & Substitute Parts Reference

Part Overview

The RC1608J623CS is a 62 kOhms ±5% 0.1W thick film chip resistor in 0603 (1608 Metric) package manufactured by Samsung Electro-Mechanics. This component is classified as Active product status with 871 pieces currently in stock. The part is designed for general-purpose applications requiring moisture-resistant thick film construction with standard tolerance specifications.

Equivalent and substitute parts are necessary when the primary manufacturer part becomes unavailable, when design requirements demand enhanced specifications such as tighter tolerance or automotive qualification, or when supply chain optimization requires alternative sourcing from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608J623CS is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 62 kOhms
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Variations:

• Tolerance: ±5% (primary specification) or tighter (±1%)
• Temperature coefficient: ±100ppm/°C (primary) or ±200ppm/°C (acceptable)
• Features: Moisture resistant (primary) or automotive AEC-Q200 qualification (enhanced)
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel®

Substitute parts are grouped into three categories based on specification alignment: Direct equivalents maintain identical electrical and mechanical parameters; Upgrade substitutes offer enhanced specifications such as tighter tolerance or automotive qualification; Similar substitutes provide equivalent functionality with additional certifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection: RC0603JR-0762KL (YAGEO) is the primary direct equivalent. This part maintains identical electrical specifications (62 kOhms ±5%, 0.1W, ±100ppm/°C) and mechanical compatibility with the RC1608J623CS. Both parts feature moisture-resistant thick film construction, operate across -55°C to 155°C, and are packaged in Tape & Reel format. YAGEO RC0603JR-0762KL is Active status with 459,064 pieces in inventory, providing reliable supply continuity.

Upgrade Substitutes for Enhanced Specifications: When tighter tolerance is required, RC0603FR-0762KL (YAGEO) or RMCF0603FT62K0 (Stackpole) provide ±1% tolerance while maintaining all other critical parameters. Both are Active status with substantial inventory.

For automotive applications requiring AEC-Q200 qualification, select from: ERJ-3EKF6202V (Panasonic, ±1% tolerance), AC0603JR-0762KL (YAGEO, ±5% tolerance with moisture resistance), or RMCF0603JT62K0 (Stackpole, ±5% tolerance). All three are Active status.

Avoid: MCR03ERTJ623 (Rohm Semiconductor) is marked as Discontinued at DiGi Electronics and should not be selected for new designs despite technical compatibility.

Frequently Asked Questions (FAQ)

Q: Can RC0603JR-0762KL replace RC1608J623CS in all applications? A: Yes. RC0603JR-0762KL is a direct equivalent with identical resistance (62 kOhms), tolerance (±5%), power rating (0.1W), temperature coefficient (±100ppm/°C), and package (0603). Both feature moisture-resistant thick film construction and operate across -55°C to 155°C.

Q: What is the difference between ±5% and ±1% tolerance substitutes? A: Tolerance specifies the maximum deviation from the nominal 62 kOhm value. ±5% allows deviation up to ±3.1 kOhms; ±1% allows deviation up to ±0.62 kOhms. Applications requiring tighter resistance accuracy should specify ±1% parts such as RC0603FR-0762KL or RMCF0603FT62K0.

Q: Are automotive AEC-Q200 qualified parts compatible with non-automotive applications? A: Yes. AEC-Q200 qualification indicates enhanced reliability testing and is a superset of standard specifications. Parts such as AC0603JR-0762KL, ERJ-3EKF6202V, and RMCF0603JT62K0 are fully compatible with non-automotive applications.

Q: What is the significance of temperature coefficient differences (±100ppm/°C vs ±200ppm/°C)? A: Temperature coefficient indicates resistance change per degree Celsius. ±100ppm/°C produces smaller resistance drift across temperature extremes than ±200ppm/°C. Applications with strict temperature stability requirements should select parts with ±100ppm/°C specification.

Q: Does packaging format (Tape & Reel vs Cut Tape) affect electrical performance? A: No. Packaging format affects only handling, storage, and assembly processes. Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® formats are mechanically compatible with standard pick-and-place equipment. Selection depends on production volume and assembly line configuration.

Q: Why is MCR03ERTJ623 listed if it is discontinued? A: MCR03ERTJ623 is documented as a historical equivalent for reference purposes. The Discontinued at DiGi Electronics status indicates it should not be selected for new designs. Use active alternatives such as RC0603JR-0762KL or RMCF0603JT62K0 instead.

Q: Can I use ERJ-3GEYJ623V if my application requires ±100ppm/°C temperature coefficient? A: No. ERJ-3GEYJ623V specifies ±200ppm/°C temperature coefficient. Select ERJ-3EKF6202V (Panasonic) or RC0603FR-0762KL (YAGEO) if ±100ppm/°C is required.
