Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RC0603J431CS is determined by the following mandatory parameters:

Primary Matching Criteria:

• Resistance value: 430 Ohms (exact match required)
• Package / Case: 0201 (0603 Metric) (exact match required)
• Power rating: 0.05W, 1/20W (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Secondary Compatibility Parameters:

• Tolerance: ±5% or tighter (±1% acceptable as upgrade)
• Temperature coefficient: ±250ppm/°C or better
• Operating temperature range: -55°C ~ 125°C minimum
• RoHS3 compliance required
• MSL 1 rating required

Substitute parts are grouped into two categories: Upgrade parts offer improved tolerance (±1% vs ±5%) while maintaining all primary specifications, and Similar parts match all primary criteria with identical or equivalent secondary parameters.

Parameter Comparison

Engineering Selection Recommendations

RC0603F431CS (Samsung Electro-Mechanics): Direct upgrade substitute with improved ±1% tolerance. Maintains identical operating temperature range, temperature coefficient, and all compliance certifications. Active product status with higher inventory availability (8711 pcs). Suitable for applications requiring tighter resistance tolerance while preserving all environmental and regulatory specifications.

CRCW0201430RFKED (Vishay Dale): Upgrade substitute offering ±1% tolerance and superior temperature coefficient (±100ppm/°C vs ±250ppm/°C). Extended operating temperature range to 155°C provides additional thermal margin. Active product status with highest inventory (10914 pcs). Recommended for precision applications or environments with elevated temperature exposure.

MCR006YRTF4300 (Rohm Semiconductor): Similar substitute with ±1% tolerance and identical temperature coefficient. Discontinued at DiGi Electronics but maintains full RoHS3 and MSL 1 compliance. Suitable for applications where tolerance upgrade is required and product discontinuation status is acceptable. Inventory availability: 18013 pcs.

MCR006YRTJ431 (Rohm Semiconductor): Direct tolerance match (±5%) with identical electrical specifications. Discontinued at DiGi Electronics status limits suitability for new designs. Inventory availability: 12420 pcs. Applicable only where existing stock requirements or legacy system compatibility necessitate this specific part.

Frequently Asked Questions (FAQ)

Q: Can RC0603F431CS replace RC0603J431CS in all applications?

A: Yes. RC0603F431CS is a direct substitute with improved tolerance (±1% vs ±5%). All primary specifications match exactly: 430 Ohms resistance, 0.05W power rating, 0201 package, thick film composition. Operating temperature range, temperature coefficient, and compliance certifications are identical. The tighter tolerance provides enhanced precision without any compatibility concerns.

Q: What is the difference between the Samsung and Vishay alternatives?

A: RC0603F431CS (Samsung) and CRCW0201430RFKED (Vishay) both offer ±1% tolerance. CRCW0201430RFKED provides superior temperature coefficient (±100ppm/°C vs ±250ppm/°C) and extended operating range to 155°C. Selection depends on thermal environment requirements and supplier preference. Both are Active status products.

Q: Why are MCR006YRTF4300 and MCR006YRTJ431 marked as discontinued?

A: These Rohm Semiconductor parts are discontinued at DiGi Electronics, indicating they are no longer actively stocked through this distribution channel. However, inventory remains available (18013 and 12420 pcs respectively). Discontinuation status does not affect electrical performance or compliance certifications but may impact long-term supply availability for new designs.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original RC0603J431CS specifications. This ensures regulatory compliance across all alternatives.

Q: Can I use a ±1% tolerance part where ±5% is specified?

A: Yes. Tighter tolerance (±1%) is always compatible with applications designed for ±5% tolerance. The component will perform within the original specification window with improved accuracy. This is considered an upgrade substitution.

Q: What packaging formats are available?

A: RC0603J431CS is supplied in Tape & Reel (TR) format. RC0603F431CS is available in Cut Tape (CT). CRCW0201430RFKED is supplied in Tape & Reel (TR). MCR006YRTF4300 and MCR006YRTJ431 are available in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on assembly process requirements and order quantity.

Q: Are all parts identical in physical dimensions?

A: Yes. All substitute parts share identical physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum seated height of 0.010" (0.26mm). Package designation 0201 (0603 Metric) is consistent across all alternatives, ensuring mechanical compatibility in PCB layouts.
