Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F5492CS are classified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Parameters (Must Match Exactly):

• Resistance value: 54.9 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

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 optional; Automotive AEC-Q200 certification is optional enhancement
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® are interchangeable supply formats

Substitutes are organized into three categories: Direct equivalents (identical specifications), Upgrade options (enhanced power rating), and Similar alternatives (additional certifications or features).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection: CR0402-FX-5492GLF (Bourns Inc.) and RC0402FR-0754K9L (YAGEO) function as direct electrical and mechanical equivalents to RC1005F5492CS. Both maintain identical resistance, tolerance, power rating, package dimensions, and temperature specifications. RC0402FR-0754K9L includes moisture resistant designation matching the original part. Selection between these options is determined by supply availability and packaging format preference (Tape & Reel versus Cut Tape & Digi-Reel®).

Upgrade Option: ERJ-2RKF5492X (Panasonic Electronic Components) provides enhanced power rating of 0.1W (1/10W) compared to the baseline 0.063W specification. This upgrade maintains all other critical parameters and adds Automotive AEC-Q200 certification. This option is suitable for applications requiring increased thermal margin or automotive-grade reliability.

Enhanced Alternatives with Automotive Certification: AC0402FR-0754K9L (YAGEO), CRCW040254K9FKED (Vishay Dale), and RMCF0402FT54K9 (Stackpole Electronics Inc) maintain baseline electrical specifications while incorporating Automotive AEC-Q200 qualification. AC0402FR-0754K9L additionally includes moisture resistant characteristics. These options are appropriate for automotive applications or designs requiring AEC-Q200 compliance.

All substitute parts maintain ROHS3 compliance, Moisture Sensitivity Level 1 (Unlimited), and identical operating temperature range (-55°C to 155°C).

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-5492GLF replace RC1005F5492CS in all applications? A: CR0402-FX-5492GLF is electrically and mechanically equivalent with identical resistance (54.9 kOhms), tolerance (±1%), power rating (0.063W), package (0402), and temperature specifications. The primary difference is absence of explicit moisture resistant designation in the CR0402 series. Substitution is valid for applications where moisture resistance is not a design requirement.

Q: What is the difference between the 0.063W and 0.1W power ratings? A: ERJ-2RKF5492X provides 0.1W (1/10W) power rating compared to the baseline 0.063W (1/16W). This represents approximately 59% higher power dissipation capability. The upgrade is suitable for circuits with higher current demands or thermal stress conditions. All other electrical parameters remain identical.

Q: Are the automotive AEC-Q200 variants suitable for non-automotive applications? A: Yes. AC0402FR-0754K9L, CRCW040254K9FKED, and RMCF0402FT54K9 meet automotive qualification standards but are electrically and mechanically compatible with non-automotive designs. AEC-Q200 certification indicates enhanced reliability testing and is not detrimental to general-purpose applications.

Q: What is the significance of Moisture Sensitivity Level 1? A: MSL 1 (Unlimited) indicates the component has unlimited shelf life without moisture bake-out requirements. This is the least restrictive moisture sensitivity classification and simplifies inventory management and assembly processes.

Q: Can packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) affect component performance? A: Packaging format affects supply chain logistics and assembly handling but does not alter electrical or mechanical performance. Both formats contain identical components; selection is based on manufacturing process requirements and inventory management preferences.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the original RC1005F5492CS specification.
