Substitute Part Grouping Explanation

Substitute parts for the WR02X4990FAL are identified based on electrical and mechanical parameter equivalence. The substitution criteria are strictly limited to the following parameters:

• Resistance value: 499 Ohms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package format: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 125°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Parts meeting all of these criteria are classified as direct substitutes. Variations in physical dimensions (height, length, width) within standard manufacturing tolerances do not disqualify substitution eligibility, provided all electrical specifications and compliance certifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the WR02X4990FAL and CR0201-20W-4990FT are active production components with identical electrical specifications and compliance certifications. Selection between these parts is based on procurement availability, supply chain logistics, and inventory requirements rather than technical performance differences.

The WR02X4990FAL (Walsin Technology Corporation) and CR0201-20W-4990FT (Venkel) are direct functional equivalents. Both components satisfy the same application requirements for 499 Ohm ±1% thick film chip resistors in 0201 package format with 0.05W power rating and ±200ppm/°C temperature coefficient. Both maintain RoHS3 compliance and MSL 1 moisture sensitivity rating across the full -55°C to 125°C operating temperature range.

Component selection should prioritize availability, lead time, and cost considerations. Both manufacturers provide equivalent reliability and performance characteristics for this resistor specification.

Frequently Asked Questions (FAQ)

Q: Can CR0201-20W-4990FT be used as a direct replacement for WR02X4990FAL in existing designs?

A: Yes. Both components share identical electrical specifications (499 Ohms ±1%, 0.05W, ±200ppm/°C), package format (0201), composition (thick film), and compliance certifications (RoHS3, MSL 1). No design modifications are required for substitution.

Q: Are there dimensional differences between these two parts?

A: Both components conform to the 0201 (0603 Metric) package standard with identical length (0.024" / 0.60mm) and width (0.012" / 0.30mm). Maximum seated height for WR02X4990FAL is 0.010" (0.26mm) and for CR0201-20W-4990FT is 0.012" (0.30mm). These variations fall within standard manufacturing tolerances for the 0201 package and do not affect PCB assembly or electrical performance.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both WR02X4990FAL and CR0201-20W-4990FT carry MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture-related storage or handling restrictions.

Q: Are both parts RoHS compliant?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the temperature coefficient specification for both parts?

A: Both components have a temperature coefficient of ±200ppm/°C across the operating temperature range of -55°C to 125°C, ensuring consistent resistance stability across thermal variations.

Q: Can these parts be used interchangeably in high-precision applications?

A: Yes. Both components maintain ±1% tolerance specification, providing equivalent precision for applications requiring this tolerance level. The identical temperature coefficient (±200ppm/°C) ensures matching thermal performance characteristics.
