Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F1052CS are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitutability:

Critical Parameters (Must Match Exactly):

• Resistance value: 10.5 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Number of Terminations: 2
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Power rating: 0.063W (1/16W) or higher (0.1W / 1/10W acceptable as upgrade)
• Physical dimensions: Height may vary within ±0.001" (±0.03mm) from seated maximum
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® acceptable
• Compliance certifications: Additional certifications (AEC-Q200) do not disqualify substitution
• Features: Additional features (Automotive qualification, Moisture Resistant) do not disqualify substitution

Substitutes are categorized as Direct (identical specifications), Upgrade (higher power rating), or Similar (additional certifications or features).

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Identical Specifications):

CR0402-FX-1052GLF (Bourns Inc.) and RC0402FR-0710K5L (YAGEO) are direct equivalents to the RC1005F1052CS. Both parts match all critical electrical parameters, package dimensions, and compliance requirements. These parts are suitable for one-to-one replacement without circuit redesign or qualification testing.

Upgrade Substitute (Higher Power Rating):

ERJ-2RKF1052X (Panasonic Electronic Components) provides a 0.1W (1/10W) power rating compared to the 0.063W (1/16W) specification of the main part. This upgrade maintains all other electrical parameters and operating characteristics. The higher power rating provides additional thermal margin in applications where power dissipation approaches the component limit. This part carries AEC-Q200 automotive qualification.

Similar Substitutes (Additional Certifications or Features):

AC0402FR-0710K5L (YAGEO), CRCW040210K5FKED (Vishay Dale), CRCW040210K5FKTD (Vishay Dale), and RMCF0402FT10K5 (Stackpole Electronics Inc) are functionally equivalent with additional certifications or features. AC0402FR-0710K5L and RMCF0402FT10K5 include AEC-Q200 automotive qualification and maintain ROHS3 compliance. CRCW040210K5FKED also carries AEC-Q200 qualification with ROHS3 compliance. CRCW040210K5FKTD is RoHS non-compliant and REACH affected; this part is suitable only for applications where RoHS exemptions apply.

All substitute parts maintain the critical operating temperature range of -55°C to 155°C and Moisture Sensitivity Level 1 (Unlimited) classification.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-0710K5L replace RC1005F1052CS in all applications?

A: Yes. RC0402FR-0710K5L is a direct equivalent with identical resistance, tolerance, power rating, package, and operating temperature specifications. No circuit modifications are required.

Q: What is the difference between the main part and ERJ-2RKF1052X?

A: ERJ-2RKF1052X has a higher power rating of 0.1W (1/10W) versus 0.063W (1/16W) for the RC1005F1052CS. All other electrical parameters are identical. The upgrade provides additional thermal headroom and includes AEC-Q200 automotive qualification.

Q: Are the Similar substitutes fully compatible with RC1005F1052CS?

A: Yes. Similar substitutes (AC0402FR-0710K5L, CRCW040210K5FKED, RMCF0402FT10K5) meet all critical electrical and mechanical parameters. Additional features such as AEC-Q200 certification do not affect compatibility. CRCW040210K5FKTD is RoHS non-compliant and should be used only in applications with RoHS exemptions.

Q: Does packaging format affect substitutability?

A: Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®) does not affect electrical or mechanical compatibility. Selection depends on assembly process requirements and inventory management practices.

Q: What is the significance of Moisture Sensitivity Level 1?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. Storage and handling do not require special humidity control or baking procedures prior to soldering.

Q: Can I use CRCW040210K5FKTD in a RoHS-compliant application?

A: No. CRCW040210K5FKTD is RoHS non-compliant and REACH affected. Use only in applications where RoHS exemptions are documented and approved. For RoHS-compliant designs, select CRCW040210K5FKED instead.

Q: Are all substitute parts in active production?

A: Yes. All listed substitute parts maintain active product status with current manufacturing availability.
