Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CRCW08056K34FKEAC are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 6.34 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance Parameters (Must Match):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

All identified substitute parts meet these criteria and are therefore suitable for direct replacement in applications where the CRCW08056K34FKEAC is specified.

Parameter Comparison

Engineering Selection Recommendations

CRCW08056K34FKEAC (Vishay Dale) - Primary specification. Active product status with continuous manufacturing support. Suitable for new designs and production applications requiring long-term component availability.

CR0805-FX-6341ELF (Bourns Inc.) - Direct substitute with active product status. Includes moisture-resistant thick film composition as an additional feature. Identical electrical and mechanical parameters. Recommended for applications where enhanced moisture resistance is beneficial or where Bourns supply chain is preferred.

MCR10ERTF6341 (Rohm Semiconductor) - Functionally equivalent substitute. Discontinued at DiGi Electronics but electrically and mechanically identical. Maximum seated height is 0.026" (0.65mm) compared to 0.024" (0.60mm) for primary and Bourns alternatives. Suitable only for applications where the additional 0.002" height clearance is acceptable and existing inventory is available.

Frequently Asked Questions (FAQ)

Q: Can MCR10ERTF6341 be used as a direct replacement for CRCW08056K34FKEAC?

A: Yes, MCR10ERTF6341 is electrically and mechanically equivalent. The seated height difference of 0.002" (0.05mm) is within typical PCB assembly tolerances for 0805 packages. However, verify clearance in applications with height-critical constraints.

Q: What is the difference between the Vishay Dale and Bourns alternatives?

A: Both parts are electrically identical with matching resistance, tolerance, power rating, and temperature specifications. CR0805-FX-6341ELF includes moisture-resistant thick film composition. Seated height is identical at 0.024" (0.60mm). Selection depends on supply availability and preference for moisture-resistant construction.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. CRCW08056K34FKEAC, MCR10ERTF6341, and CR0805-FX-6341ELF are all ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited) and REACH Unaffected status.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. All three parts meet identical electrical specifications (6.34 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C) and are packaged in 0805 (2012 Metric) with two terminations. They are suitable for direct substitution in PCB designs without circuit modification.

Q: Why is MCR10ERTF6341 listed as discontinued?

A: MCR10ERTF6341 is discontinued at DiGi Electronics but remains functionally equivalent. Availability depends on alternative distributors and existing inventory. For new production designs, CRCW08056K34FKEAC or CR0805-FX-6341ELF are recommended for assured long-term supply.
