Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F4752CS is determined by strict equivalence across the following critical parameters: resistance value (47.5 kOhms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and termination count (2). Power rating may vary within acceptable limits for the application. All substitute parts listed maintain these core electrical and mechanical specifications. Substitutes are categorized as direct equivalents, upgrades, or similar alternatives based on additional features such as automotive qualification (AEC-Q200) or enhanced power ratings, while maintaining full compatibility with the original part's footprint and electrical performance envelope.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Drop-In Replacement): CR0402-FX-4752GLF (Bourns Inc.) and RC0402FR-0747K5L (YAGEO) are direct electrical and mechanical equivalents to the RC1005F4752CS. Both maintain identical resistance, tolerance, power rating, package format, and temperature specifications. RC0402FR-0747K5L additionally includes moisture-resistant construction matching the original part. Both are ROHS3 compliant and available in Tape & Reel packaging.

Upgrade Option (Enhanced Specification): ERJ-2RKF4752X (Panasonic Electronic Components) provides an upgrade path with increased power rating (0.1W versus 0.063W) while maintaining all other electrical parameters. This part includes Automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability. ROHS3 compliance is maintained.

Automotive-Qualified Alternatives: AC0402FR-0747K5L (YAGEO), CRCW040247K5FKED (Vishay Dale), CRCW040247K5FKTD (Vishay Dale), and RMCF0402FT47K5 (Stackpole Electronics Inc) all feature Automotive AEC-Q200 certification. AC0402FR-0747K5L and RMCF0402FT47K5 are ROHS3 compliant. CRCW040247K5FKED is available in Cut Tape & Digi-Reel packaging. CRCW040247K5FKTD is RoHS non-compliant and REACH affected, requiring compliance verification before selection.

Compliance Considerations: For applications requiring ROHS3 compliance and REACH unaffected status, select from: CR0402-FX-4752GLF, RC0402FR-0747K5L, ERJ-2RKF4752X, AC0402FR-0747K5L, CRCW040247K5FKED, or RMCF0402FT47K5. CRCW040247K5FKTD does not meet these requirements.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-4752GLF replace RC1005F4752CS in all applications? A: Yes. CR0402-FX-4752GLF is a direct equivalent with identical electrical specifications (47.5 kOhms ±1%, 0.063W, ±100ppm/°C) and package format (0402). Both are ROHS3 compliant with MSL 1. Footprint and performance are fully compatible.

Q: What is the difference between the main part and ERJ-2RKF4752X? A: ERJ-2RKF4752X has a higher power rating (0.1W versus 0.063W) and includes Automotive AEC-Q200 qualification. All other electrical parameters remain identical. This part is suitable for applications requiring automotive-grade reliability or higher power dissipation capability.
