Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F4022CS is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters (Must Match Exactly):

• Resistance value: 40.2 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2

Allowable Variations:

• Power Rating: Substitute parts may equal or exceed 0.063W (1/16W)
• Height - Seated: Substitute parts may equal or be less than 0.016" (0.40mm)
• Features: Substitute parts may include additional features (moisture resistance, automotive certification, anti-sulfur treatment) without compromising base functionality
• Packaging Format: Cut Tape (CT), Digi-Reel®, or Tape & Reel (TR) formats are interchangeable based on procurement requirements
• Compliance: Substitute parts must maintain ROHS3 compliance and MSL 1 rating

Substitute parts are categorized as follows:

Direct Substitutes: Parts meeting all critical parameters with identical or superior power ratings and no additional restrictions.

Upgrade Substitutes: Parts exceeding the power rating specification while maintaining all other critical parameters, suitable for applications requiring enhanced thermal performance.

Similar Substitutes: Parts meeting all critical parameters with additional certifications (AEC-Q200 automotive qualification, anti-sulfur treatment) or enhanced features, applicable to designs with expanded environmental or reliability requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Equivalent Functionality):

The CR0402-FX-4022GLF (Bourns Inc.) and RC0402FR-0740K2L (YAGEO) are direct functional equivalents to the RC1005F4022CS. Both parts maintain identical electrical specifications, package dimensions, and compliance certifications. The RC0402FR-0740K2L additionally incorporates moisture-resistant construction matching the original part. Selection between these options depends on packaging format requirements and supplier availability.

Upgrade Substitute (Enhanced Power Rating):

The ERJ-2RKF4022X (Panasonic Electronic Components) provides a 0.1W (1/10W) power rating, exceeding the original 0.063W specification. This part is suitable for applications requiring improved thermal margin or higher dissipation capability. The component carries Automotive AEC-Q200 certification, indicating qualification for automotive-grade reliability standards. This upgrade is applicable when design margins require enhanced power handling without changing the physical footprint or electrical characteristics.

Similar Substitutes (Enhanced Features and Certifications):

The AC0402FR-0740K2L, AF0402FR-0740K2L (YAGEO), CRCW040240K2FKED, CRCW040240K2FKTD (Vishay Dale), and RMCF0402FT40K2 (Stackpole Electronics Inc) all incorporate Automotive AEC-Q200 certification. These parts are suitable for applications subject to automotive environmental and reliability requirements. The AF0402FR-0740K2L additionally includes anti-sulfur treatment for enhanced corrosion resistance in harsh environments.

Compliance Considerations:

All substitute parts except CRCW040240K2FKTD maintain ROHS3 compliance. The CRCW040240K2FKTD is RoHS non-compliant and REACH affected, restricting its use in applications with mandatory RoHS compliance requirements. This part should be selected only when legacy design requirements or specific supply chain constraints necessitate its use.

Packaging Format Selection:

Tape & Reel (TR) packaging is suitable for high-volume automated assembly operations. Cut Tape (CT) and Digi-Reel® formats provide flexibility for lower-volume production or mixed-component procurement. Selection should align with manufacturing process capabilities and inventory management requirements.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-2RKF4022X be used as a direct replacement for the RC1005F4022CS?

A: The ERJ-2RKF4022X is functionally compatible with the RC1005F4022CS for all electrical and mechanical parameters. The primary difference is the enhanced 0.1W power rating compared to the original 0.063W specification. This upgrade is suitable for applications where additional thermal margin is beneficial. The component occupies the same 0402 package footprint and operates across the identical temperature range.

Q: What is the significance of AEC-Q200 certification on substitute parts?

A: AEC-Q200 certification indicates that the component meets Automotive Electronics Council qualification standards for passive components in automotive applications. This certification encompasses reliability testing, environmental stress screening, and failure rate analysis specific to automotive operating conditions. Parts carrying this certification are suitable for automotive-grade designs but are not required for general industrial or consumer applications.

Q: Are Cut Tape (CT) and Tape & Reel (TR) formats interchangeable?

A: Cut Tape and Tape & Reel formats are packaging delivery methods that do not affect component electrical or mechanical performance. Selection depends on manufacturing process requirements. Tape & Reel format is optimized for automated pick-and-place assembly systems. Cut Tape format provides flexibility for manual assembly or lower-volume production runs. Both formats contain identical components with identical specifications.

Q: Why is CRCW040240K2FKTD marked as RoHS non-compliant?

A: The CRCW040240K2FKTD does not meet ROHS3 compliance requirements, indicating the presence of restricted substances above specified thresholds. This part should be selected only when design requirements explicitly permit non-compliant components or when legacy system constraints necessitate its use. For new designs subject to RoHS compliance mandates, select alternative parts carrying ROHS3 Compliant status.

Q: What is the difference between moisture-resistant and standard thick film construction?

A: Moisture-resistant thick film construction incorporates protective coating or material composition that reduces susceptibility to moisture ingress and associated performance degradation. The RC1005F4022CS and RC0402FR-0740K2L both feature moisture-resistant construction. Standard thick film parts without this feature are suitable for controlled environment applications but may experience performance drift in high-humidity conditions. Selection should align with application environmental exposure requirements.

Q: Can substitute parts with anti-sulfur treatment be used in standard applications?

A: Anti-sulfur treatment, as featured in the AF0402FR-0740K2L, provides enhanced corrosion resistance in environments with hydrogen sulfide exposure or high-sulfur atmospheric conditions. This treatment does not negatively impact performance in standard applications and may be selected when enhanced environmental durability is desired without additional cost or complexity constraints.

Q: What inventory considerations apply when selecting substitute parts?

A: Inventory availability varies significantly across substitute options. The ERJ-2RKF4022X (Panasonic) maintains the highest inventory level at 464,895 units, while the AC0402FR-0740K2L (YAGEO) has the lowest at 2,200 units. Selection should consider both immediate procurement requirements and long-term supply chain stability. Higher inventory levels generally indicate better availability for future replenishment.
