Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F9311CS are classified based on electrical and mechanical parameter alignment:

Direct Equivalents maintain identical specifications across resistance value, tolerance, power rating, package format, temperature coefficient, and operating temperature range. These parts are interchangeable without design modification.

Upgrade Substitutes provide enhanced performance through increased power rating (0.1W vs. 0.063W) or additional certifications (AEC-Q200 automotive qualification) while maintaining all other critical parameters. These parts support higher thermal stress applications.

Similar Substitutes match core electrical specifications and package format but may include automotive AEC-Q200 qualification or alternative moisture-resistant features. These parts are suitable for applications requiring automotive-grade reliability or enhanced environmental protection.

Substitution eligibility is determined by:

• Resistance value: 9.31 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package: 0402 (1005 Metric) (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature: -55°C ~ 155°C (exact match required)
• Composition: Thick Film (exact match required)

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection: CR0402-FX-9311GLF (Bourns Inc.) and RC0402FR-079K31L (YAGEO) provide direct electrical and mechanical equivalence to the RC1005F9311CS. Both maintain identical power ratings, temperature coefficients, and operating ranges. RC0402FR-079K31L includes moisture-resistant construction matching the original specification.

Upgrade Path: ERJ-2RKF9311X (Panasonic Electronic Components) offers increased power dissipation capability (0.1W vs. 0.063W) with AEC-Q200 automotive qualification. This part is suitable for applications requiring enhanced thermal performance or automotive-grade reliability without design modification to the 0402 package footprint.

Automotive-Grade Alternatives: AC0402FR-079K31L (YAGEO), CRCW04029K31FKED (Vishay Dale), and RMCF0402FT9K31 (Stackpole Electronics Inc) provide AEC-Q200 certification with maintained electrical specifications. AC0402FR-079K31L includes moisture-resistant features. These parts support automotive applications and high-reliability environments while preserving the original 0.063W power rating and 0402 package format.

All substitute parts maintain RoHS3 compliance, MSL 1 rating, and identical operating temperature ranges (-55°C ~ 155°C). Selection should be based on application requirements for automotive qualification, moisture resistance, and thermal margin.

Frequently Asked Questions (FAQ)

Q: Can ERJ-2RKF9311X replace RC1005F9311CS in any application? A: ERJ-2RKF9311X is electrically and mechanically compatible. The increased power rating (0.1W vs. 0.063W) provides additional thermal margin and does not create incompatibility. The 0402 package footprint remains identical. AEC-Q200 certification is an additional qualification that does not restrict use in non-automotive applications.

Q: What is the difference between moisture-resistant and non-moisture-resistant variants? A: Moisture-resistant construction (RC1005F9311CS, RC0402FR-079K31L, AC0402FR-079K31L) provides enhanced protection in humid environments. Both types maintain MSL 1 (Unlimited) rating. Selection depends on application environment and assembly process requirements.

Q: Are automotive AEC-Q200 parts suitable for non-automotive applications? A: Yes. AEC-Q200 certification indicates enhanced reliability testing and qualification. These parts exceed standard requirements and are fully compatible with non-automotive designs. No design modification is required.

Q: Can I substitute based on package size alone? A: No. All substitute parts must match the complete electrical specification set: 9.31 kOhms resistance, ±1% tolerance, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. Package format (0402) is necessary but not sufficient for substitution.

Q: What inventory considerations apply to these substitutes? A: Substitute parts maintain varying stock levels. CR0402-FX-9311GLF (Bourns) provides 69,800 units. RC0402FR-079K31L (YAGEO) provides 742,497 units. RMCF0402FT9K31 (Stackpole) provides 126,163 units. Availability should be confirmed for production volume requirements.

Q: Do all parts share identical physical dimensions? A: All parts use 0402 (1005 Metric) package with 0.039" L x 0.020" W footprint. Height-seated maximum varies slightly: RC1005F9311CS, CR0402-FX-9311GLF, ERJ-2RKF9311X, and RMCF0402FT9K31 are 0.016" (0.40mm). AC0402FR-079K31L is 0.015" (0.37mm). These variations are within standard PCB assembly tolerances and do not affect interchangeability.
