Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F1182CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 11.8 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS3 Compliance

Power Rating Consideration: Parts are classified into two groups based on power rating. Direct substitutes maintain the 0.063W (1/16W) rating. Upgrade substitutes provide enhanced 0.1W (1/10W) power capability while maintaining all other electrical and mechanical specifications.

Automotive Qualification: Some substitute parts include AEC-Q200 automotive qualification. This represents an enhancement to the base specification and does not restrict substitution in non-automotive applications.

Packaging Format: Substitute parts are available in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats. Packaging format selection depends on assembly process requirements and does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Equivalent Specifications):

CR0402-FX-1182GLF (Bourns Inc.) and RC0402FR-0711K8L (YAGEO) are direct functional equivalents to the RC1005F1182CS. Both parts maintain identical electrical specifications, package format, and power rating. RC0402FR-0711K8L includes moisture resistance matching the primary part. Selection between these options depends on packaging format preference (Tape & Reel versus Cut Tape & Digi-Reel®) and inventory availability.

Enhanced Substitutes (Automotive Qualified):

AC0402FR-0711K8L (YAGEO), CRCW040211K8FKED (Vishay Dale), and RMCF0402FT11K8 (Stackpole Electronics Inc) provide AEC-Q200 automotive qualification in addition to meeting all base electrical and mechanical specifications. These parts are suitable for applications requiring automotive-grade components and offer enhanced reliability documentation. AC0402FR-0711K8L additionally includes moisture resistance.

Upgrade Substitute (Enhanced Power Rating):

ERJ-2RKF1182X (Panasonic Electronic Components) provides increased power dissipation capability at 0.1W (1/10W) compared to the 0.063W (1/16W) rating of the primary part. This part includes AEC-Q200 automotive qualification. The upgrade is applicable in designs where thermal margin improvement is beneficial, provided PCB layout and thermal management accommodate the component.

All substitute parts maintain RoHS3 compliance, MSL 1 moisture sensitivity rating, and the specified operating temperature range of -55°C to 155°C.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-1182GLF be used as a direct replacement for RC1005F1182CS?

A: Yes. CR0402-FX-1182GLF meets all electrical and mechanical specifications of the RC1005F1182CS, including 11.8 kOhms resistance, ±1% tolerance, 0.063W power rating, 0402 package format, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and RoHS3 compliance. The primary difference is packaging format (Tape & Reel) and manufacturer.

Q: What is the difference between the 0.063W and 0.1W power-rated parts?

A: The ERJ-2RKF1182X provides 0.1W (1/10W) power dissipation capability compared to 0.063W (1/16W) in the primary part and most substitutes. This higher power rating allows the component to dissipate greater thermal energy. All other electrical and mechanical parameters remain identical. The upgrade is applicable when circuit design requires additional thermal margin.

Q: Are automotive-qualified parts suitable for non-automotive applications?

A: Yes. Automotive-qualified parts such as AC0402FR-0711K8L, CRCW040211K8FKED, and RMCF0402FT11K8 meet or exceed the specifications of non-automotive equivalents. AEC-Q200 qualification represents enhanced reliability documentation and testing. These parts are fully compatible with non-automotive designs.

Q: Does packaging format (Tape & Reel versus Cut Tape) affect electrical performance?

A: No. Packaging format affects only the physical delivery and handling method during assembly. Electrical and mechanical specifications remain identical regardless of packaging format. Selection depends on assembly equipment compatibility and process requirements.

Q: Is moisture resistance a critical parameter for substitution?

A: Moisture resistance is a feature present in the primary part (RC1005F1182CS) and some substitutes (RC0402FR-0711K8L, AC0402FR-0711K8L). All parts maintain MSL 1 (Unlimited) moisture sensitivity rating, indicating minimal moisture absorption risk. Substitutes without explicit moisture resistance designation remain fully compatible with the primary part specification.

Q: Can I use AC0402FR-0711K8L in place of RC1005F1182CS?

A: Yes. AC0402FR-0711K8L is electrically and mechanically equivalent to RC1005F1182CS. It provides identical resistance, tolerance, power rating, package format, and operating temperature range. The part includes AEC-Q200 automotive qualification and moisture resistance, representing an enhancement to the base specification. The maximum seated height is 0.015" (0.37mm) compared to 0.016" (0.40mm) for the primary part, which is within acceptable PCB layout tolerances.

Q: What inventory considerations apply to these substitute parts?

A: Inventory availability varies by manufacturer and part number. RC0402FR-0711K8L (YAGEO) has 2,400 units available. CR0402-FX-1182GLF (Bourns Inc.) has 25,083 units. RMCF0402FT11K8 (Stackpole Electronics Inc) has 273,116 units. AC0402FR-0711K8L (YAGEO) has 6,265 units. CRCW040211K8FKED (Vishay Dale) has 59,191 units. ERJ-2RKF1182X (Panasonic Electronic Components) has 94,530 units. Selection based on inventory availability supports supply chain continuity.
