Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F8R2CS is determined by strict equivalence across the following parameters: resistance value (8.2 Ohms), tolerance (±1%), power rating (0.1W), package type (0603/1608 Metric), composition (thick film), operating temperature range (-55°C to 155°C), and compliance certifications (RoHS3, MSL 1). All identified substitute parts maintain these core electrical and mechanical specifications. Temperature coefficient variations (±200ppm/°C versus ±300ppm/°C) and additional feature designations (Automotive AEC-Q200, Current Sense, High Voltage) represent enhanced or specialized capabilities that do not disqualify substitution but indicate extended qualification or application scope.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (ERJ-3RQF8R2V, KTR03EZPF8R20, RMCF0603FT8R20) are functionally equivalent to the RC1608F8R2CS based on core electrical and mechanical parameters. Selection among these alternatives is determined by application-specific requirements and supply chain considerations:

ERJ-3RQF8R2V (Panasonic Electronic Components): Qualified to Automotive AEC-Q200 standard with current sense capability. Temperature coefficient of ±200ppm/°C provides improved stability compared to the primary part. Suitable for automotive and precision measurement applications requiring enhanced temperature performance.

KTR03EZPF8R20 (Rohm Semiconductor): Qualified to Automotive AEC-Q200 standard with high voltage designation. Temperature coefficient of ±200ppm/°C. Appropriate for automotive circuits and high-voltage applications within the 0.1W power envelope.

RMCF0603FT8R20 (Stackpole Electronics Inc): Qualified to Automotive AEC-Q200 standard. Temperature coefficient of ±200ppm/°C. Physical length of 1.55mm (versus 1.60mm nominal) remains within 0603 package specification tolerance. Suitable for automotive applications with standard PCB layout compatibility.

All substitute parts maintain Active product status, RoHS3 compliance, and MSL 1 rating, ensuring long-term availability and environmental regulatory adherence.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3RQF8R2V replace RC1608F8R2CS in any application?

A: ERJ-3RQF8R2V meets all core electrical specifications (8.2 Ohms ±1%, 0.1W, 0603 package) and environmental ratings (RoHS3, MSL 1, -55°C to 155°C). The improved temperature coefficient (±200ppm/°C versus ±300ppm/°C) and AEC-Q200 qualification represent enhanced performance characteristics. Direct substitution is valid for standard applications; automotive or precision applications benefit from the additional qualification.

Q: What is the significance of AEC-Q200 qualification on the substitute parts?

A: AEC-Q200 is an automotive industry standard qualification for passive components. All three substitute parts carry this certification, indicating validation for automotive temperature cycling, vibration, and reliability requirements. The primary RC1608F8R2CS does not list AEC-Q200 qualification. Substitution with AEC-Q200 qualified parts is appropriate for automotive applications; non-automotive applications do not require this certification.

Q: Are there physical compatibility concerns with RMCF0603FT8R20 due to its 1.55mm length?

A: RMCF0603FT8R20 has a length of 1.55mm compared to the nominal 1.60mm of other parts. This 0.05mm difference remains within standard 0603 package tolerance and does not affect PCB footprint compatibility, solder reflow processing, or electrical performance. Physical placement and assembly are equivalent.

Q: How do temperature coefficient differences affect circuit performance?

A: The RC1608F8R2CS specifies ±300ppm/°C while substitute parts specify ±200ppm/°C. This means substitute parts exhibit smaller resistance value changes across the -55°C to 155°C operating range. For a 210°C temperature span, the RC1608F8R2CS tolerance band expands by approximately 0.063 Ohms maximum, while substitute parts expand by approximately 0.042 Ohms maximum. Selection depends on circuit tolerance requirements; precision applications benefit from the lower temperature coefficient.

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

A: All parts listed (RC1608F8R2CS, ERJ-3RQF8R2V, KTR03EZPF8R20, RMCF0603FT8R20) are specified with Tape & Reel (TR) packaging, suitable for automated assembly processes. Packaging format is consistent across all options.

Q: What compliance certifications apply to all parts?

A: All parts are RoHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity level). ECCN classification is EAR99 for all parts. HTSUS code 8533.21.0030 applies uniformly. Regulatory and trade compliance is equivalent across all options.
