Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 442 Ohms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Moisture Sensitivity Level: MSL 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

Allowable Variation:

• Power Rating: Substitutes may equal or exceed the 0.063W specification
• Packaging Format: Cut Tape (CT) and Tape & Reel (TR) formats are interchangeable for component selection purposes
• Automotive Certification: AEC-Q200 rating is an enhancement and does not restrict substitution

The substitute parts are categorized as follows:

Direct Substitute: RC0402FR-07442RL (YAGEO) — Identical electrical and mechanical specifications with Tape & Reel packaging.

Upgrade Substitute: ERJ-2RKF4420X (Panasonic) — Enhanced power rating (0.1W vs. 0.063W) with automotive AEC-Q200 qualification.

Similar Substitutes: AC0402FR-07442RL (YAGEO), CRCW0402442RFKED (Vishay Dale), RMCF0402FT442R (Stackpole Electronics) — All meet base specifications with automotive AEC-Q200 certification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): RC0402FR-07442RL (YAGEO) is the primary direct substitute. This part maintains all electrical and mechanical parameters of the RC1005F4420CS while offering equivalent performance in Tape & Reel packaging format. Both parts are Active status with ROHS3 compliance and MSL 1 rating.

For Enhanced Reliability (Automotive Applications): ERJ-2RKF4420X (Panasonic) provides an upgrade path with increased power rating (0.1W vs. 0.063W) and AEC-Q200 automotive qualification. This part is suitable for applications requiring automotive-grade components while maintaining all other electrical specifications.

For Automotive-Grade Standard Specifications: AC0402FR-07442RL (YAGEO), CRCW0402442RFKED (Vishay Dale), and RMCF0402FT442R (Stackpole Electronics) are functionally equivalent alternatives with AEC-Q200 certification. These parts maintain the 0.063W power rating and all other base specifications while offering automotive qualification.

All listed substitutes maintain Active product status, ROHS3 compliance, and MSL 1 moisture sensitivity rating. Selection among equivalent parts may be based on packaging format preference (Cut Tape vs. Tape & Reel), supplier availability, or design requirements for automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-07442RL replace RC1005F4420CS in any application? A: Yes. RC0402FR-07442RL is a direct substitute with identical electrical specifications (442 Ω ±1%, 0.063W), matching package (0402), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and regulatory compliance (ROHS3, MSL 1).

Q: What is the difference between Cut Tape and Tape & Reel packaging? A: Cut Tape (CT) and Tape & Reel (TR) are packaging and delivery formats only. Both contain identical components. Cut Tape is supplied in smaller quantities on cut strips, while Tape & Reel is supplied on continuous reels for automated assembly. Electrical and mechanical specifications are unchanged.

Q: Can ERJ-2RKF4420X be used where RC1005F4420CS is specified? A: Yes, with the note that ERJ-2RKF4420X has a higher power rating (0.1W vs. 0.063W). This upgrade does not create compatibility issues. The part maintains all other specifications including resistance, tolerance, package, temperature coefficient, and operating range. AEC-Q200 automotive certification is an additional qualification.

Q: Are the automotive-rated substitutes (AC0402FR-07442RL, CRCW0402442RFKED, RMCF0402FT442R) required for non-automotive applications? A: No. AEC-Q200 certification is an enhancement. For non-automotive applications, RC0402FR-07442RL provides direct equivalence without automotive qualification. Automotive-rated parts may be used in non-automotive designs without restriction.

Q: What parameters must match exactly for substitution? A: Resistance (442 Ω), tolerance (±1%), package (0402), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), MSL rating (1), and RoHS status (ROHS3) must match exactly. Power rating may equal or exceed the original specification.

Q: Is moisture sensitivity level (MSL 1) the same across all listed parts? A: Yes. All listed parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions and no baking requirement prior to soldering.

Q: Can these 0402 resistors be used interchangeably on the same PCB? A: Yes. All listed parts share identical 0402 (1005 Metric) package dimensions: 0.039" L × 0.020" W (1.00mm × 0.50mm) with maximum seated height of 0.016" to 0.017" (0.40mm to 0.37mm). PCB footprints and assembly processes remain unchanged.
