Engineering Selection Recommendations

Direct Equivalents (Same Manufacturer - Vishay Dale)

CRCW0805280RFKEA is a direct equivalent from Vishay Dale with identical electrical specifications and package dimensions. This part offers improved RoHS3 compliance compared to the CRCW0805280RFKTC and maintains the same 0.50mm maximum seated height. Selection of CRCW0805280RFKEA is appropriate when RoHS3 compliance is required and supply of the original part is constrained.

Cross-Manufacturer Substitutes (Equivalent Specifications)

ERJ-6ENF2800V (Panasonic), RMCF0805FT280R (Stackpole), and KTR10EZPF2800 (Rohm) are functionally equivalent across all critical electrical parameters. All three maintain AEC-Q200 automotive rating and ROHS3 compliance. Physical height variations (0.65mm to 0.70mm maximum seated height) are within typical PCB design tolerances for 0805 packages. These parts are suitable for direct substitution in applications where supply diversification or cost optimization is required.

Discontinued Part Status

MCR10ERTF2800 (Rohm Semiconductor) is discontinued at DiGi Electronics. While electrically equivalent, this part should not be selected for new designs or long-term production due to end-of-life status.

Frequently Asked Questions (FAQ)

Q: Can I substitute CRCW0805280RFKEA for CRCW0805280RFKTC?

A: Yes. Both parts are manufactured by Vishay Dale with identical electrical specifications (280 Ohms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C, AEC-Q200). The primary difference is RoHS compliance status. CRCW0805280RFKEA is ROHS3 compliant while CRCW0805280RFKTC is non-compliant. Physical dimensions are identical.

Q: Are cross-manufacturer substitutes (Panasonic, Stackpole, Rohm) fully compatible?

A: Yes. ERJ-6ENF2800V, RMCF0805FT280R, and KTR10EZPF2800 meet all specified electrical and mechanical parameters. All are AEC-Q200 rated, ROHS3 compliant, and packaged in 0805 (2012 Metric). Seated height variations (0.50mm to 0.70mm) are within standard PCB design margins for this package class.

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

A: Maximum seated height ranges from 0.50mm to 0.70mm across the listed parts. This variation is typical for 0805 thick film resistors and does not affect electrical performance or standard PCB assembly processes. Verify clearance in your specific PCB layout if height-constrained applications are present.

Q: Why is MCR10ERTF2800 listed if it is discontinued?

A: MCR10ERTF2800 is documented as a historical equivalent for reference purposes. This part is discontinued at DiGi Electronics and should not be selected for new designs or production orders.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect substitutability?

A: Packaging format affects supply chain logistics and handling but does not affect electrical or mechanical compatibility. CRCW0805280RFKEA, ERJ-6ENF2800V, RMCF0805FT280R, and KTR10EZPF2800 are available in Tape & Reel format. MCR10ERTF2800 is available in Cut Tape & Digi-Reel format. Select based on your assembly process requirements.

Q: Are all substitute parts suitable for automotive applications?

A: Yes. All listed substitute parts carry AEC-Q200 automotive rating and operate across the -55°C to 155°C temperature range specified for the original part.
