Key Parameters

Substitute Part Grouping Explanation

Substitution for the CRCW0805634RFKTC is determined by strict equivalence across the following parameters: resistance value (634 Ohms), tolerance (±1%), power rating (0.125W), package type (0805 / 2012 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and automotive qualification (AEC-Q200). All identified substitute parts match these core electrical and mechanical specifications. Packaging format (Tape & Reel versus Cut Tape) does not affect electrical or mechanical compatibility and is noted for procurement purposes only.

Parameter Comparison

Engineering Selection Recommendations

CRCW0805634RFKEA (Vishay Dale) is the direct equivalent with identical electrical specifications and same-manufacturer sourcing. This part is ROHS3 compliant and available in higher inventory (13,073 pcs), making it the primary substitute for the CRCW0805634RFKTC.

ERJ-6ENF6340V (Panasonic Electronic Components) and RMCF0805FT634R (Stackpole Electronics Inc) are cross-manufacturer equivalents that meet all electrical and automotive qualification requirements. Both are ROHS3 compliant with substantial inventory availability. Height variation (0.70mm for Panasonic, 0.65mm for Stackpole versus 0.50mm for Vishay) must be evaluated for PCB layout constraints in space-critical applications.

MCR10ERTF6340 (Rohm Semiconductor) is listed as discontinued at DiGi Electronics and lacks AEC-Q200 automotive certification. This part is not recommended for new automotive designs requiring AEC-Q200 compliance.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805634RFKEA be used as a direct replacement for CRCW0805634RFKTC?

A: Yes. Both parts share identical electrical specifications (634 Ω ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C), package dimensions (0805 / 2.00mm x 1.25mm), and AEC-Q200 automotive rating. The difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and RoHS compliance status.

Q: Are cross-manufacturer substitutes electrically equivalent?

A: Yes. ERJ-6ENF6340V, RMCF0805FT634R, and MCR10ERTF6340 all match the core electrical parameters: 634 Ohm resistance, ±1% tolerance, 0.125W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. All are 0805 package with 2-pin terminations.

Q: Does the height difference between substitute parts affect compatibility?

A: Height variation (0.50mm to 0.70mm) is within standard 0805 package tolerance but must be evaluated for specific PCB layout requirements. Panasonic ERJ-6ENF6340V (0.70mm max height) and Stackpole RMCF0805FT634R (0.65mm max height) are taller than the original Vishay part (0.50mm). Confirm clearance in your PCB design before selection.

Q: Why is MCR10ERTF6340 not recommended?

A: MCR10ERTF6340 is discontinued at DiGi Electronics and does not carry AEC-Q200 automotive certification. For automotive applications requiring AEC-Q200 compliance, use CRCW0805634RFKEA, ERJ-6ENF6340V, or RMCF0805FT634R instead.

Q: What is the difference between RoHS non-compliant and ROHS3 compliant parts?

A: CRCW0805634RFKTC is RoHS non-compliant, while CRCW0805634RFKEA, ERJ-6ENF6340V, RMCF0805FT634R, and MCR10ERTF6340 are ROHS3 compliant. ROHS3 compliance indicates restriction of hazardous substances per EU Directive 2011/65/EU. Select ROHS3 compliant alternatives for applications subject to RoHS regulations.
