Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603F392CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 3.9 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W minimum (equal or greater acceptable)
• Composition: Thick Film

Mechanical Parameters:

• Package / Case: 0201 (0603 Metric) (exact match required)
• Termination count: 2 (exact match required)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (equal or better acceptable)

Substitute parts are classified as either Direct or Similar based on temperature coefficient and operating temperature range alignment with the primary part.

Engineering Selection Recommendations

CRCW02013K90FKED (Vishay Dale) - Direct Substitute:

This part is the primary direct substitute for the RC0603F392CS. It maintains identical electrical specifications (3.9 kOhms ±1%, 0.05W) and mechanical compatibility (0201 package). The Vishay Dale CRCW series demonstrates superior temperature coefficient performance (±100ppm/°C versus ±250ppm/°C) and extended operating temperature range (-55°C to 155°C versus -55°C to 125°C). Both parts are ROHS3 compliant with MSL 1 rating. Inventory availability is significantly higher (28,235 units in stock). This part is suitable for direct replacement in all applications where the RC0603F392CS is specified.

MCR006YRTF3901 (Rohm Semiconductor) - Similar Substitute:

This part matches all critical electrical and mechanical parameters with the RC0603F392CS, including identical temperature coefficient (±250ppm/°C) and operating temperature range (-55°C to 125°C). However, the MCR006YRTF3901 is listed as discontinued at DiGi Electronics, indicating limited future availability. The part is supplied in Cut Tape (CT) & Digi-Reel® packaging rather than standard Tape & Reel format. This part is suitable for substitution only when supply of the primary part and CRCW02013K90FKED is unavailable, and when packaging format compatibility can be accommodated in assembly processes.

Frequently Asked Questions (FAQ)

Q: Can CRCW02013K90FKED be used as a direct replacement for RC0603F392CS without circuit redesign?

A: Yes. Both parts share identical resistance (3.9 kOhms), tolerance (±1%), power rating (0.05W), and package (0201). The CRCW02013K90FKED offers improved temperature stability (±100ppm/°C) and wider operating range (-55°C to 155°C), making it functionally superior in these aspects. No circuit modifications are required.

Q: What is the difference between the temperature coefficients of these parts?

A: The RC0603F392CS and MCR006YRTF3901 both specify ±250ppm/°C temperature coefficient. The CRCW02013K90FKED specifies ±100ppm/°C, indicating lower resistance drift across temperature variations. For applications with tight tolerance requirements across temperature extremes, the Vishay Dale part provides superior performance.

Q: Why is MCR006YRTF3901 marked as discontinued?

A: The MCR006YRTF3901 is discontinued at DiGi Electronics, indicating this distributor no longer actively stocks or supports this part. This status does not reflect manufacturer discontinuation but rather distributor inventory decisions. Availability through alternative channels may vary.

Q: Are there packaging differences between these substitutes?

A: The RC0603F392CS and CRCW02013K90FKED are supplied in Tape & Reel (TR) format. The MCR006YRTF3901 is supplied in Cut Tape (CT) & Digi-Reel® format. Both formats are compatible with standard pick-and-place assembly equipment, though reel specifications may differ. Verify compatibility with your specific assembly process requirements.

Q: Do all three parts meet RoHS compliance requirements?

A: Yes. All three parts (RC0603F392CS, CRCW02013K90FKED, and MCR006YRTF3901) are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting standard environmental and regulatory requirements for commercial and industrial applications.
