Substitute Part Grouping Explanation

Substitution eligibility for the RCS040219K1FKED is determined by strict equivalence across the following critical parameters:

• Resistance value: 19.1 kOhms
• Tolerance: ±1%
• Power rating: 0.2W (1/5W)
• Package: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Pulse withstanding capability
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The substitute part CRCW040219K1FKEDHP meets all these criteria and is therefore a direct functional equivalent. Both parts are manufactured by Vishay Dale, share identical electrical and mechanical specifications, and carry equivalent automotive and environmental certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RCS040219K1FKED and CRCW040219K1FKEDHP are active production components manufactured by Vishay Dale with identical electrical, mechanical, and environmental specifications. Selection between these parts may be based on:

• Inventory availability: RCS040219K1FKED has 9802 units in stock; CRCW040219K1FKEDHP has 10956 units in stock
• Series designation: RCS040219K1FKED belongs to the RCS e3 series; CRCW040219K1FKEDHP belongs to the CRCW-HP series
• Supply chain requirements and procurement lead times
• Design documentation and historical usage patterns

Both parts satisfy AEC-Q200 automotive qualification, ROHS3 compliance, and REACH requirements. No performance degradation or functional compromise occurs when substituting between these parts in applications requiring 19.1 kOhms ±1% thick film resistors in 0402 package with -55°C to 155°C operating range.

Frequently Asked Questions (FAQ)

Q: Can CRCW040219K1FKEDHP be used as a direct replacement for RCS040219K1FKED?
