Substitute Part Grouping Explanation

Substitute parts for the RC1005F3091CS are classified based on strict equivalence of the following critical parameters:

Primary Equivalence Criteria:

• Resistance value: 3.09 kOhms
• Tolerance: ±1%
• Package: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100 ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitution Categories:

Direct Equivalents maintain identical electrical and mechanical specifications with interchangeable packaging formats (Tape & Reel or Cut Tape).

Upgrade Substitutes exceed the power rating specification while maintaining all other electrical parameters, providing enhanced thermal performance for the same footprint.

Similar Substitutes include additional automotive qualification (AEC-Q200) or enhanced moisture resistance features while maintaining core electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection: CR0402-FX-3091GLF (Bourns Inc.) and RC0402FR-073K09L (YAGEO) provide complete electrical and mechanical equivalence to the RC1005F3091CS. Both maintain identical resistance, tolerance, power rating, package dimensions, and temperature specifications. RC0402FR-073K09L includes moisture resistant characteristics matching the reference part. Selection between these direct equivalents depends on packaging preference (Tape & Reel versus Cut Tape & Digi-Reel) and inventory availability.

Upgrade Selection: ERJ-2RKF3091X (Panasonic Electronic Components) provides enhanced power rating at 0.1W (1/10W) while maintaining all other electrical parameters. This upgrade is suitable for applications requiring additional thermal margin or where component stress reduction is beneficial. The part includes Automotive AEC-Q200 qualification, extending its application scope to automotive environments.

Similar Substitutes with Enhanced Qualification: AC0402FR-073K09L (YAGEO), CRCW04023K09FKED (Vishay Dale), and RMCF0402FT3K09 (Stackpole Electronics Inc) incorporate Automotive AEC-Q200 qualification while maintaining core specifications. AC0402FR-073K09L additionally includes moisture resistant features. These parts are appropriate for applications requiring automotive-grade reliability or where AEC-Q200 compliance is specified.

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and identical operating temperature range (-55°C to 155°C), ensuring direct functional compatibility within the specified environmental and regulatory constraints.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-3091GLF replace RC1005F3091CS in all applications? A: CR0402-FX-3091GLF provides complete electrical and mechanical equivalence. The primary difference is the absence of documented moisture resistant features in the Bourns part specification. For applications where moisture resistance is not explicitly required, this direct equivalent is suitable. Verify application requirements before selection.

Q: What is the advantage of selecting ERJ-2RKF3091X over the reference part? A: ERJ-2RKF3091X provides a higher power rating (0.1W versus 0.063W) in the identical 0402 package footprint. This upgrade reduces component thermal stress in power-dissipating applications and includes Automotive AEC-Q200 qualification for automotive applications. Electrical performance (resistance, tolerance, temperature coefficient) remains identical.

Q: Are the AEC-Q200 qualified parts (AC0402FR-073K09L, CRCW04023K09FKED, RMCF0402FT3K09) suitable for non-automotive applications? A: Yes. Automotive AEC-Q200 qualification represents enhanced reliability testing and quality standards. These parts are fully compatible with non-automotive applications and provide equivalent or superior performance compared to non-qualified alternatives. Selection should be based on application requirements and cost considerations.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Both packaging formats contain identical components. Tape & Reel packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape & Digi-Reel packaging provides smaller quantities on cut tape segments. Selection depends on production volume and assembly equipment compatibility.

Q: Can I use RC0402FR-073K09L (YAGEO) as a direct replacement for RC1005F3091CS? A: Yes. RC0402FR-073K09L matches all critical electrical and mechanical specifications and includes moisture resistant characteristics identical to the reference part. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel). Verify assembly equipment compatibility with the selected packaging format.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), matching the regulatory and environmental specifications of the reference part RC1005F3091CS.

Q: What determines whether a part is classified as a Direct Equivalent, Upgrade, or Similar Substitute? A: Classification is based on strict parameter matching. Direct Equivalents maintain identical specifications across all electrical and mechanical parameters. Upgrades exceed power rating while maintaining other specifications. Similar Substitutes include additional features (such as AEC-Q200 qualification) while maintaining core electrical parameters. All classifications ensure functional compatibility within specified constraints.
