CRCW0805634RFKEBC Equivalent & Substitute Parts

Part Overview

The CRCW0805634RFKEBC is a 634 Ohm ±1% thick film chip resistor manufactured by Vishay Dale in the 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation with an operating temperature range of -55°C to 155°C. The part maintains Active product status with 1088 units currently in stock as new original inventory.

Substitute parts become necessary when the primary manufacturer part experiences supply constraints, extended lead times, or when design flexibility permits equivalent component selection from alternative manufacturers while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW0805634RFKEBC is determined by strict equivalence across the following parameters:

• Resistance value: 634 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Package format: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

The MCR10ERTF6340 manufactured by Rohm Semiconductor satisfies all substitution criteria and qualifies as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MCR10ERTF6340 is a qualified substitute for the CRCW0805634RFKEBC based on complete electrical and mechanical parameter equivalence. Both components meet ROHS3 compliance requirements and carry identical regulatory classifications (EAR99, HTSUS 8533.21.0030).

The primary distinction between these parts is product status: the CRCW0805634RFKEBC maintains Active status with current inventory availability, while the MCR10ERTF6340 is listed as Discontinued at DiGi Electronics. Selection between these components should prioritize availability and supply chain requirements rather than technical performance, as both deliver identical functional characteristics within the specified operating envelope.

The maximum seated height differential of 0.002" (0.05mm) between the two parts falls within standard PCB assembly tolerances and does not present a constraint for substitution in standard surface-mount applications.

Frequently Asked Questions (FAQ)

Q: Can the MCR10ERTF6340 be used as a direct replacement for the CRCW0805634RFKEBC in production designs?

A: Yes. Both components share identical electrical specifications (634 Ohms ±1%, 0.125W, ±100ppm/°C) and mechanical package format (0805 / 2012 Metric). The components are functionally interchangeable within the specified operating temperature range of -55°C to 155°C.

Q: Are there any height or dimensional constraints when substituting between these parts?

A: The seated height difference is 0.002" (0.05mm), with the MCR10ERTF6340 at 0.026" maximum versus the CRCW0805634RFKEBC at 0.024" maximum. This variance is within standard PCB assembly and reflow process tolerances and does not require design modification.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both components are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both parts.

Q: What is the primary reason to consider the MCR10ERTF6340 as a substitute?

A: The MCR10ERTF6340 should be considered when the CRCW0805634RFKEBC experiences supply constraints or extended lead times. However, the CRCW0805634RFKEBC maintains Active status with current inventory, making it the preferred primary selection when availability permits.

Q: Are packaging formats different between these two parts?

A: Both components are supplied in 0805 (2012 Metric) package format. The CRCW0805634RFKEBC is available in Tape & Reel (TR) packaging, while the MCR10ERTF6340 is supplied in Cut Tape (CT) & Digi-Reel® format. This packaging difference does not affect component performance or compatibility.
