Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F305CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 3 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: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Temperature coefficient: ±100ppm/°C or ±200ppm/°C (within specified range)
• Physical dimensions: Minor variations within 0603 package specification
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel®
• Additional features: Automotive AEC-Q200 qualification (upgrade feature, not required)

Substitute parts are categorized as Direct, Upgrade, or Similar based on feature alignment with the original specification.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (RC0603FR-073ML - YAGEO): This part matches all electrical and mechanical parameters of the RC1608F305CS with identical tolerance, temperature coefficient, and moisture resistant characteristics. Selection is appropriate for direct replacement in non-automotive applications requiring standard industrial specifications.

Upgrade Options (KTR03EZPF3004, RMCF0603FT3M00, AC0603FR-073ML, CRCW06033M00FKEA): These parts satisfy all mandatory parameters while adding Automotive AEC-Q200 qualification. Selection is appropriate when application requirements include automotive-grade reliability or when enhanced supply chain availability is prioritized. The KTR03EZPF3004 includes high voltage capability. The RMCF0603FT3M00 specifies ±200ppm/°C temperature coefficient, which remains within acceptable operating range but differs from the original ±100ppm/°C specification.

Compliance Verification: All substitute parts maintain ROHS3 compliance, Moisture Sensitivity Level 1 (Unlimited), and identical operating temperature range (-55°C ~ 155°C). All parts are Active product status with established supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-073ML be used as a direct replacement for RC1608F305CS?

A: Yes. RC0603FR-073ML is a direct equivalent. Both parts share identical electrical specifications (3 MOhms ±1%, 0.1W), thermal characteristics (±100ppm/°C, -55°C ~ 155°C), package format (0603), and moisture resistant properties. No design modification is required.

Q: What is the difference between the original part and the automotive-qualified substitutes?

A: The original RC1608F305CS is specified for general industrial applications. The substitute parts KTR03EZPF3004, RMCF0603FT3M00, AC0603FR-073ML, and CRCW06033M00FKEA include Automotive AEC-Q200 qualification, indicating compliance with automotive reliability and testing standards. All other electrical and mechanical parameters remain equivalent.

Q: Does the ±200ppm/°C temperature coefficient of RMCF0603FT3M00 affect compatibility?

A: The RMCF0603FT3M00 specifies ±200ppm/°C compared to the original ±100ppm/°C. Both values fall within the operating temperature range of -55°C ~ 155°C. Selection depends on application tolerance requirements. For applications requiring tighter temperature stability, the ±100ppm/°C options (RC0603FR-073ML, KTR03EZPF3004, AC0603FR-073ML, CRCW06033M00FKEA) are preferred.

Q: Are there packaging format differences among the substitute parts?

A: RC1608F305CS, RC0603FR-073ML, KTR03EZPF3004, RMCF0603FT3M00, and AC0603FR-073ML are supplied in Tape & Reel (TR) format. CRCW06033M00FKEA is supplied in Cut Tape (CT) & Digi-Reel® format. Both formats are compatible with standard pick-and-place assembly equipment. Selection depends on procurement and assembly process requirements.

Q: What is the Moisture Sensitivity Level (MSL) significance?

A: All listed parts specify MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Components can be stored and handled without special moisture control measures. This specification is identical across all substitute options.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance, matching the original RC1608F305CS specification. This ensures regulatory compliance for applications subject to ROHS directives.
