CRCW0805787RFKEAC Equivalent & Substitute Parts

Part Overview

The CRCW0805787RFKEAC is a 787 Ohm ±1% 0.125W thick film chip resistor in 0805 (2012 Metric) package manufactured by Vishay Dale. This component is currently active in production with 1,102 pieces available in stock. The part is specified for applications requiring precision resistive elements with tight tolerance and stable performance across the operating temperature range of -55°C to 155°C. Substitute parts are necessary when primary sourcing becomes unavailable, when inventory constraints require alternative suppliers, or when design flexibility permits equivalent component selection.

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW0805787RFKEAC is determined by strict equivalence across the following critical parameters:

• Resistance value: 787 Ohms (exact match required)
• Tolerance: ±1% (no deviation permitted)
• Power rating: 0.125W minimum
• Package: 0805 (2012 Metric) form factor
• Composition: Thick film construction
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum
• RoHS3 compliance and MSL 1 rating

The MCR10ERTF7870 manufactured by Rohm Semiconductor meets all substitution criteria. Both components share identical electrical specifications, package geometry, and environmental compliance ratings. Physical dimensions remain within acceptable tolerance, with maximum seated height varying by 0.002" (0.05mm), which does not impact PCB assembly or circuit performance.

Parameter Comparison

Engineering Selection Recommendations

The CRCW0805787RFKEAC remains the primary component choice due to active production status and confirmed inventory availability. The MCR10ERTF7870 is electrically and mechanically equivalent but carries discontinued status at major distributors, limiting long-term sourcing reliability.

Selection between these components should be based on:

• Current inventory requirements and lead time constraints
• Supplier availability and pricing at the time of procurement
• Long-term production volume and supply chain stability
• Compliance requirements: both components satisfy ROHS3 and REACH requirements with EAR99 export classification

For new designs or production runs requiring extended component availability, the CRCW0805787RFKEAC is the recommended primary selection. The MCR10ERTF7870 is suitable only when existing inventory is available and immediate delivery is prioritized over long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can MCR10ERTF7870 be used as a direct replacement for CRCW0805787RFKEAC in existing designs?

A: Yes. Both components are electrically identical with matching resistance, tolerance, power rating, and temperature specifications. Physical dimensions are equivalent within manufacturing tolerance. No circuit redesign or PCB layout modification is required.

Q: What is the significance of the 0.002" height difference between the two parts?

A: The maximum seated height difference (0.024" versus 0.026") is within standard PCB assembly tolerance and does not affect component placement, solder joint formation, or circuit performance. Both parts are compatible with standard 0805 assembly processes.

Q: Are both parts suitable for high-reliability applications?

A: Both components meet ROHS3 compliance and carry MSL 1 (Unlimited) moisture sensitivity rating, indicating suitability for standard commercial and industrial applications. Specific reliability requirements should be evaluated against application-level specifications.

Q: Why is MCR10ERTF7870 listed as discontinued?

A: Discontinued status indicates the part is no longer actively produced or stocked by major distributors. Existing inventory may remain available through secondary sources, but long-term availability cannot be assured.

Q: What parameters must match exactly for substitution eligibility?

A: Resistance value (787 Ohms), tolerance (±1%), power rating (0.125W minimum), package (0805), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C) must all match. Deviations in any parameter disqualify substitution.
