Engineering Selection Recommendations

CRCW02015K10FKED (Vishay Dale) – Primary Substitute

This part is the preferred direct equivalent for new designs and component replacement. It maintains all mandatory electrical and mechanical specifications while offering an extended operating temperature range (-55°C ~ 155°C) compared to the original RC0603F512CS (-55°C ~ 125°C). The tighter temperature coefficient (±100ppm/°C versus ±250ppm/°C) provides superior stability across temperature variations. Both parts carry ROHS3 compliance, MSL 1 classification, and identical physical dimensions. Tape & Reel packaging ensures compatibility with standard pick-and-place assembly processes. Current inventory availability is substantial (135,503 pcs), supporting production continuity.

MCR006YRTF5101 (Rohm Semiconductor) – Secondary Substitute

This part functions as an equivalent alternative with identical electrical specifications and physical form factor. The temperature coefficient matches the original part (±250ppm/°C), and the operating temperature range is identical (-55°C ~ 125°C). However, this component is classified as Discontinued at DiGi Electronics, indicating limited future availability. The packaging format differs (Cut Tape & Digi-Reel® versus Tape & Reel), which may require process adjustment for automated assembly. This part is suitable for existing inventory applications or low-volume production where packaging format variation is acceptable. Current inventory is limited (1,429 pcs).

Selection Criteria Summary:

• For new designs and high-volume production: Select CRCW02015K10FKED
• For applications requiring extended temperature performance: Select CRCW02015K10FKED
• For existing stock replacement with packaging flexibility: MCR006YRTF5101 is acceptable
• All three parts meet RoHS3 and MSL 1 requirements for standard commercial applications

Frequently Asked Questions (FAQ)

Q1: Can CRCW02015K10FKED be used as a direct replacement for RC0603F512CS without circuit redesign?

A: Yes. Both parts share identical resistance value (5.1 kOhms), tolerance (±1%), power rating (0.05W), package (0201), and physical dimensions (0.024" L x 0.012" W). The CRCW02015K10FKED offers improved temperature stability (±100ppm/°C) and extended operating range (-55°C ~ 155°C), making it functionally superior for direct substitution.

Q2: What is the significance of the temperature coefficient difference between RC0603F512CS (±250ppm/°C) and CRCW02015K10FKED (±100ppm/°C)?

A: Temperature coefficient defines resistance value drift per degree Celsius. The CRCW02015K10FKED exhibits 2.5 times lower drift, resulting in more stable resistance values across the operating temperature range. For precision analog circuits, this provides improved performance. For general-purpose applications, both specifications are acceptable.

Q3: Why is MCR006YRTF5101 listed as a substitute if it is discontinued?

A: MCR006YRTF5101 meets all mandatory electrical and mechanical specifications for functional equivalence. Discontinued status indicates no new production; however, existing inventory (1,429 pcs) remains available. This part is suitable for applications where current stock is sufficient or for replacement scenarios in existing equipment.

Q4: Are there packaging format differences between the substitute parts?

A: RC0603F512CS and CRCW02015K10FKED are supplied in Tape & Reel (TR) format, compatible with standard automated assembly equipment. MCR006YRTF5101 uses Cut Tape (CT) & Digi-Reel® format, which may require manual handling or alternative feeder systems. Both formats contain identical components; the difference is in supply presentation only.

Q5: Do all three parts comply with RoHS3 and MSL 1 requirements?

A: Yes. RC0603F512CS, CRCW02015K10FKED, and MCR006YRTF5101 are all ROHS3 compliant and classified as MSL 1 (Unlimited moisture sensitivity level). All parts are suitable for standard commercial applications without special moisture control during storage or handling.

Q6: What is the basis for determining substitution eligibility?

A: Substitution is based on matching mandatory parameters: resistance value, tolerance, power rating, package type, physical dimensions, composition, and regulatory compliance. Allowable variations include temperature coefficient (within specified ranges), operating temperature upper limit (extended ranges acceptable), and packaging format (both TR and CT acceptable). Product status (Active or Discontinued) does not disqualify a part if inventory is available.

Q7: Which substitute part should be selected for a new product design?

A: CRCW02015K10FKED is the recommended choice for new designs. It is Active status with high inventory availability (135,503 pcs), offers superior temperature stability, and provides extended operating range. This ensures long-term supply continuity and optimal circuit performance.
