Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F1022CS are qualified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Parameters (Must Match Exactly):

• Resistance value: 10.2 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100 ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant
• Number of Terminations: 2

Allowable Variation Parameters:

• Power Rating: 0.063W (1/16W) baseline; 0.1W (1/10W) represents an upgrade with enhanced thermal capability
• Features: Moisture Resistant designation is compatible; Automotive AEC-Q200 certification is an additional qualification that does not preclude substitution
• Height - Seated (Max): Minor dimensional variations (0.015" to 0.016") within standard 0402 package tolerance

Substitute parts are categorized as follows:

Direct Equivalents: Parts with identical electrical specifications, power rating, and core features (CR0402-FX-1022GLF, RC0402FR-0710K2L)

Upgrade Equivalent: Part with higher power rating (ERJ-2RKF1022X at 0.1W) providing enhanced thermal margin while maintaining all other critical parameters

Similar Equivalents: Parts with identical core specifications but additional automotive qualification (AC0402FR-0710K2L, CRCW040210K2FKED, RMCF0402FT10K2)

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (No Design Changes Required):

CR0402-FX-1022GLF (Bourns Inc.) and RC0402FR-0710K2L (YAGEO) are direct functional equivalents with identical electrical and thermal specifications. Both maintain Active product status and ROHS3 compliance. RC0402FR-0710K2L includes moisture resistant construction matching the original part specification.

For Designs Requiring Automotive Qualification:

AC0402FR-0710K2L (YAGEO), CRCW040210K2FKED (Vishay Dale), and RMCF0402FT10K2 (Stackpole Electronics Inc) are qualified to AEC-Q200 automotive standards while maintaining identical core electrical parameters. These parts are suitable for applications requiring automotive-grade component certification.

For Enhanced Thermal Performance:

ERJ-2RKF1022X (Panasonic Electronic Components) provides a 0.1W power rating compared to the baseline 0.063W, offering increased thermal margin in power-dissipation-sensitive applications. This upgrade maintains all other critical specifications and includes AEC-Q200 automotive qualification.

Compliance and Regulatory Considerations:

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and operate within the specified -55°C to 155°C temperature range. All parts are classified under HTSUS 8533.21.0030 and carry EAR99 ECCN designation.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-1022GLF replace RC1005F1022CS in existing designs without modification?

A: Yes. CR0402-FX-1022GLF is a direct electrical and mechanical equivalent with identical resistance (10.2 kOhms), tolerance (±1%), power rating (0.063W), package (0402), and operating temperature range (-55°C to 155°C). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the main part and RC0402FR-0710K2L?

A: RC0402FR-0710K2L is functionally identical to RC1005F1022CS with one key addition: both parts include moisture resistant construction. All electrical parameters, package dimensions, and compliance certifications are equivalent.

Q: Why does ERJ-2RKF1022X have a higher power rating (0.1W vs 0.063W)?

A: ERJ-2RKF1022X is rated at 0.1W (1/10W) compared to the baseline 0.063W (1/16W). This represents an upgrade providing enhanced thermal dissipation capability. The higher power rating does not affect circuit operation in applications designed for 0.063W; it simply provides additional thermal margin. All other electrical specifications remain identical.

Q: Are the automotive-qualified parts (AC0402FR-0710K2L, CRCW040210K2FKED, RMCF0402FT10K2) suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification is an additional certification that does not restrict use in non-automotive applications. These parts meet or exceed the electrical and reliability requirements of the original part and are fully compatible with standard industrial and consumer applications.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. The component can be stored indefinitely at room temperature without special moisture control measures, simplifying inventory management and reducing preparation time before assembly.

Q: Are there dimensional differences between substitute parts?

A: All parts conform to the 0402 (1005 Metric) package standard with dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm). Height-seated maximum values range from 0.015" to 0.016" (0.37mm to 0.40mm), representing minor variations within standard package tolerance and do not affect PCB layout or assembly compatibility.

Q: Can these parts be mixed in the same production batch?

A: Yes, provided the design does not specify a single manufacturer requirement. All substitute parts meet identical electrical specifications and package standards. However, design documentation should specify acceptable part numbers to ensure traceability and consistency.

Q: What packaging formats are available for these substitute parts?

A: All substitute parts are available in Tape & Reel (TR) format suitable for automated assembly. ERJ-2RKF1022X is also available in Cut Tape (CT) & Digi-Reel® format, providing additional procurement flexibility.
