Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Non-Automotive Applications):

CR0402-FX-4751GLF (Bourns Inc.) and RC0402FR-074K75L (YAGEO) are direct electrical and mechanical equivalents to the RC1005F4751CS. Both maintain identical resistance, tolerance, power rating, package format, and temperature specifications. RC0402FR-074K75L includes moisture-resistant construction matching the original part. Both are ROHS3 compliant and carry unlimited MSL rating. Selection between these options depends on packaging preference (Tape & Reel versus Cut Tape & Digi-Reel®) and inventory availability.

For Automotive Applications:

AC0402FR-074K75L (YAGEO), CRCW04024K75FKED (Vishay Dale), and RMCF0402FT4K75 (Stackpole Electronics Inc) are qualified to AEC-Q200 automotive standards while maintaining electrical equivalence to the original part. AC0402FR-074K75L additionally provides moisture-resistant construction. All three are ROHS3 compliant with unlimited MSL. These parts are suitable for automotive-grade circuit applications requiring enhanced reliability qualification.

For Enhanced Power Dissipation:

ERJ-2RKF4751X (Panasonic Electronic Components) provides an upgrade path with 0.1W (1/10W) power rating compared to the original 0.063W specification. This part maintains all other electrical parameters and includes AEC-Q200 automotive qualification. Use this substitute when circuit design requires higher power handling capability within the same package footprint.

Compliance Consideration:

CRCW04024K75FKTD (Vishay Dale) is RoHS non-compliant and REACH affected. This part is not recommended for new designs or applications requiring regulatory compliance with current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can I substitute CR0402-FX-4751GLF for RC1005F4751CS in any application?

A: CR0402-FX-4751GLF is electrically and mechanically equivalent to RC1005F4751CS across all critical parameters: 4.75 kOhms ±1%, 0.063W power rating, 0402 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. The primary difference is the absence of moisture-resistant construction in the Bourns part. For applications where moisture resistance is not specified, direct substitution is valid. For moisture-sensitive environments, RC0402FR-074K75L is preferred.

Q: What is the difference between the main part and ERJ-2RKF4751X?

A: ERJ-2RKF4751X differs in two aspects: (1) enhanced power rating of 0.1W versus 0.063W in the original part, and (2) AEC-Q200 automotive qualification. All other electrical parameters remain identical. This part is suitable for applications requiring higher power dissipation or automotive-grade reliability. The higher power rating does not create compatibility issues in circuits designed for the lower 0.063W specification.

Q: Are all substitute parts available in the same packaging formats?

A: No. The original RC1005F4751CS is specified with standard packaging notation. Substitute parts are available in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats. Verify packaging compatibility with your assembly process requirements before selection. Both formats are standard for 0402 package components and do not affect electrical performance.

Q: Which substitute part should I use for automotive applications?

A: For automotive applications, select from AC0402FR-074K75L, CRCW04024K75FKED, or RMCF0402FT4K75, all of which carry AEC-Q200 qualification. AC0402FR-074K75L is recommended if moisture resistance is required. CRCW04024K75FKTD is not suitable due to RoHS non-compliance and REACH affected status.

Q: Can I use CRCW04024K75FKTD as a substitute?

A: CRCW04024K75FKTD is electrically equivalent but is RoHS non-compliant and REACH affected. This part does not meet current environmental and regulatory standards. Use CRCW04024K75FKED (ROHS3 compliant variant) instead, or select alternative AEC-Q200 qualified parts.

Q: What does MSL 1 (Unlimited) mean for substitution purposes?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. All listed substitute parts maintain MSL 1 rating, ensuring compatibility with standard component storage and assembly processes without additional moisture barrier requirements.

Q: Are there dimensional differences between substitute parts?

A: All substitute parts conform to the 0402 (1005 Metric) package standard with identical length (0.039" / 1.00mm) and width (0.020" / 0.50mm). AC0402FR-074K75L has a maximum seated height of 0.015" (0.37mm) compared to 0.016" (0.40mm) for other parts. This minor variation does not affect PCB layout or assembly compatibility.

Q: What is the temperature coefficient specification and why does it matter?

A: All parts, including the original and substitutes, have a temperature coefficient of ±100ppm/°C. This specification defines the resistance change per degree Celsius across the operating temperature range. Matching this parameter ensures consistent circuit performance across the -55°C to 155°C operating range. All listed substitutes maintain this specification.
