Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F3650CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance Value: 365 Ohms
• Tolerance: ±1%
• Power Rating: 0.1W (1/10W)
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 0603 (1608 Metric)
• Number of Terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant or equivalent
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these criteria. Parts are further categorized as Direct Manufacturer equivalents or Similar parts based on feature alignment and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Manufacturer Equivalents (Highest Interchangeability):

CR0603-FX-3650ELF (Bourns Inc.) and RC0603FR-07365RL (YAGEO) are direct functional equivalents to the RC1608F3650CS. Both parts maintain identical electrical specifications, operating temperature range, and RoHS3 compliance status. These parts are suitable for one-to-one replacement in applications where the original Samsung Electro-Mechanics component is specified.

Similar Parts with Automotive Qualification (AEC-Q200):

CRCW0603365RFKEA, CRCW0603365RFKTA (Vishay Dale), ERJ-3EKF3650V (Panasonic Electronic Components), and RMCF0603FT365R (Stackpole Electronics Inc) are qualified to AEC-Q200 automotive standards. These parts meet all electrical and mechanical parameters of the RC1608F3650CS. Selection of automotive-qualified alternatives is appropriate for applications requiring enhanced reliability and traceability.

Compliance Consideration:

CRCW0603365RFKTA is marked as RoHS non-compliant with REACH Affected status. This part is not suitable for applications requiring RoHS3 compliance. All other substitute parts maintain ROHS3 Compliant status and REACH Unaffected designation, matching the original part's compliance profile.

Packaging Consideration:

CRCW0603365RFKEA is supplied in Cut Tape & Digi-Reel packaging, while all other alternatives use standard Tape & Reel packaging. Packaging selection depends on assembly process requirements and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-3650ELF replace RC1608F3650CS in all applications?

A: Yes. CR0603-FX-3650ELF is a direct equivalent with matching resistance value (365 Ohms), tolerance (±1%), power rating (0.1W), package format (0603), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and RoHS3 compliance status. No circuit redesign or validation is required for direct substitution.

Q: What is the difference between Direct Manufacturer equivalents and Similar parts?

A: Direct Manufacturer equivalents (CR0603-FX-3650ELF and RC0603FR-07365RL) are functionally identical to the RC1608F3650CS with no additional certifications. Similar parts (CRCW0603365RFKEA, CRCW0603365RFKTA, ERJ-3EKF3650V, RMCF0603FT365R) meet all electrical and mechanical specifications but carry additional AEC-Q200 automotive qualification. Both categories are electrically interchangeable.

Q: Why is CRCW0603365RFKTA listed if it is RoHS non-compliant?

A: CRCW0603365RFKTA is included in the substitute list because it meets all electrical and mechanical parameters. However, it is not suitable for applications requiring RoHS3 compliance. Selection of this part is restricted to legacy systems or applications where RoHS compliance is not mandated.

Q: Does packaging type affect electrical performance?

A: No. Packaging type (Tape & Reel versus Cut Tape & Digi-Reel) affects only handling, storage, and assembly processes. Electrical performance and component specifications remain identical. Packaging selection is based on manufacturing and inventory requirements.

Q: Are all substitute parts available in equivalent quantities?

A: Inventory levels vary by manufacturer and distributor. RC0603FR-07365RL (YAGEO) shows the highest inventory at 57,440 pieces. ERJ-3EKF3650V (Panasonic) has 106,076 pieces available. Specific inventory availability should be confirmed with component suppliers at time of procurement.

Q: Can automotive-qualified parts (AEC-Q200) be used in non-automotive applications?

A: Yes. AEC-Q200 qualification represents enhanced reliability and quality assurance standards. Parts meeting automotive standards are suitable for general-purpose applications and provide equivalent or superior performance compared to non-qualified alternatives.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates Unlimited shelf life without moisture exposure controls. All listed parts, including the RC1608F3650CS, have MSL 1 rating, meaning they do not require special moisture-controlled storage or handling procedures prior to assembly.
