Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F106CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 10 MOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package / Case: 0603 (1608 Metric)
• Composition: Thick Film
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS compliance status

Allowable Variation Parameters:

• Temperature coefficient: ±100ppm/°C to ±200ppm/°C (within specified range)
• Physical dimensions: Minor variations within 0603 package specification
• Moisture resistance features: Base moisture resistant to enhanced automotive-grade features
• Packaging format: Cut Tape (CT), Digi-Reel®, or Tape & Reel (TR)

All identified substitute parts meet or exceed the mandatory parameters. Substitutes are categorized as Direct (functionally identical), Upgrade (enhanced features such as AEC-Q200 automotive qualification), or Similar (additional protective features such as anti-sulfur coating).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Functionally Identical):

RC0603FR-0710ML (YAGEO) is the primary direct equivalent to RC1608F106CS. Both parts share identical electrical specifications (10 MOhms ±1%, 0.1W, ±100ppm/°C), package format (0603), and compliance status (ROHS3). RC0603FR-0710ML offers significantly higher inventory availability (55300 units) compared to the main part. This substitute is suitable for applications where automotive qualification is not required.

Upgrade Substitutes (Enhanced Features):

KTR03EZPF1005 (Rohm Semiconductor), RMCF0603FG10M0 (Stackpole Electronics Inc), RMCF0603FT10M0 (Stackpole Electronics Inc), AC0603FR-0710ML (YAGEO), AF0603FR-0710ML (YAGEO), CRCW060310M0FKEA (Vishay Dale), and CRCW060310M0FKTA (Vishay Dale) all incorporate AEC-Q200 automotive qualification. These parts are suitable for applications requiring automotive-grade reliability and environmental stress screening. KTR03EZPF1005 and CRCW060310M0FKEA offer the highest inventory levels (101515 and 141432 units respectively) among automotive-qualified options.

Compliance Consideration:

CRCW060310M0FKTA is RoHS non-compliant and REACH-affected. Selection of this part is restricted to applications where RoHS exemptions apply or legacy system requirements mandate non-compliant components.

Temperature Coefficient Variation:

RMCF0603FG10M0 and RMCF0603FT10M0 feature ±200ppm/°C temperature coefficient compared to ±100ppm/°C in the main part and most substitutes. This variation remains within acceptable tolerance for general resistor applications but should be evaluated for precision analog circuits requiring tighter temperature stability.

Frequently Asked Questions (FAQ)

Q1: Can RC0603FR-0710ML be used as a direct replacement for RC1608F106CS?

A: Yes. RC0603FR-0710ML meets all mandatory electrical and mechanical parameters: 10 MOhms ±1% resistance, 0.1W power rating, 0603 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and ROHS3 compliance. Both parts are thick film composition with moisture-resistant construction. The primary difference is manufacturer (YAGEO vs. Samsung Electro-Mechanics) and packaging format availability.

Q2: What is the difference between Direct, Upgrade, and Similar substitute categories?

A: Direct substitutes (RC0603FR-0710ML) are functionally identical to the main part with no additional features. Upgrade substitutes (KTR03EZPF1005, RMCF series, AC0603FR-0710ML, AF0603FR-0710ML, CRCW series) include AEC-Q200 automotive qualification, high-voltage rating, or anti-sulfur protection. Similar substitutes share the same core specifications but may have minor variations in physical dimensions or enhanced environmental features. All categories maintain electrical equivalence across resistance, tolerance, power rating, and package.

Q3: Should I select an AEC-Q200 qualified part if my application is not automotive?

A: AEC-Q200 qualification indicates enhanced reliability through automotive-grade environmental stress screening and qualification testing. Selection of AEC-Q200 parts for non-automotive applications is permissible and may provide additional reliability margin. However, cost and lead time considerations should be evaluated against application requirements. For general industrial or consumer applications without automotive specifications, RC0603FR-0710ML provides equivalent electrical performance at potentially lower cost.

Q4: What is the significance of the ±200ppm/°C temperature coefficient in RMCF0603FG10M0 and RMCF0603FT10M0?

A: Temperature coefficient defines resistance change per degree Celsius. RMCF parts at ±200ppm/°C exhibit twice the temperature-dependent resistance variation compared to ±100ppm/°C parts. For a 10 MOhm resistor over a 100°C temperature swing, this represents a maximum 0.2% vs. 0.1% resistance change respectively. Selection depends on circuit tolerance requirements. Precision analog applications requiring tight temperature stability should specify ±100ppm/°C parts. General applications tolerate ±200ppm/°C variation.

Q5: Why is CRCW060310M0FKTA marked as RoHS non-compliant?

A: CRCW060310M0FKTA is RoHS non-compliant and REACH-affected, indicating it may contain restricted substances (lead, cadmium, hexavalent chromium, etc.) above RoHS thresholds. This part is suitable only for applications with documented RoHS exemptions or legacy systems where compliance waivers apply. For new designs and general procurement, ROHS3-compliant alternatives (CRCW060310M0FKEA, RC0603FR-0710ML, KTR03EZPF1005, RMCF series, AC0603FR-0710ML, AF0603FR-0710ML) are required.

Q6: How do packaging formats (Cut Tape, Digi-Reel®, Tape & Reel) affect part selection?

A: Packaging format affects handling, storage, and automated assembly compatibility but does not alter electrical or mechanical specifications. Cut Tape (CT) and Digi-Reel® formats are suitable for manual assembly or low-volume production. Tape & Reel (TR) format is optimized for high-speed automated pick-and-place assembly. Selection should align with manufacturing process capabilities. All identified substitutes maintain identical component specifications regardless of packaging format.

Q7: What inventory considerations should guide substitute selection?

A: RC0603FR-0710ML (55300 units), KTR03EZPF1005 (101515 units), and CRCW060310M0FKEA (141432 units) offer substantially higher inventory availability compared to RC1608F106CS (1070 units). For applications requiring large-volume procurement or extended supply chain security, these high-inventory alternatives reduce lead time risk and support production continuity. Inventory levels should be verified with suppliers as stock quantities fluctuate.
