Substitute Part Grouping Explanation

Substitution eligibility for the CRCW0805280RFKEB is determined by strict equivalence across the following parameters:

Resistance value: 280 Ohms
Tolerance: ±1%
Power rating: 0.125W (1/8W)
Package: 0805 (2012 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
Automotive qualification: AEC-Q200
RoHS compliance: ROHS3 Compliant
Moisture sensitivity: MSL 1

All substitute parts listed meet these criteria. Mechanical dimensions (length, width, height) remain within acceptable tolerances across manufacturers. Packaging format (Tape & Reel or Cut Tape) does not affect electrical equivalence but may influence procurement and assembly logistics.

Engineering Selection Recommendations

Direct substitutes CRCW0805280RFKEA, ERJ-6ENF2800V, and RMCF0805FT280R are electrically and mechanically equivalent to the primary part CRCW0805280RFKEB. All three maintain identical electrical specifications, AEC-Q200 automotive qualification, and ROHS3 compliance. Selection among these three is based on availability and packaging preference (Tape & Reel format).

KTR10EZPF2800 from Rohm Semiconductor is functionally equivalent with additional high voltage capability. This part carries the same core specifications and AEC-Q200 rating, making it suitable for applications requiring enhanced voltage performance.

MCR10ERTF2800 is electrically equivalent but carries a discontinued status at DiGi Electronics. While the part meets all electrical and mechanical requirements, procurement may face future availability constraints. This part is suitable only when alternative sources confirm continued manufacturing.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805280RFKEA be used as a direct replacement for CRCW0805280RFKEB?

A: Yes. Both parts are manufactured by Vishay Dale with identical electrical specifications (280 Ω ±1%, 0.125W), package (0805), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The difference is in the last character of the part number, which indicates packaging revision. Electrical performance is equivalent.

Q: What is the difference between ERJ-6ENF2800V and CRCW0805280RFKEB?

A: Both parts are electrically identical with 280 Ω ±1% resistance, 0.125W power rating, 0805 package, and AEC-Q200 qualification. The primary difference is manufacturer (Panasonic vs. Vishay Dale) and maximum seated height (0.028" vs. 0.020"). The height difference is within standard PCB assembly tolerances and does not affect electrical function.

Q: Is KTR10EZPF2800 a suitable substitute?

A: Yes. KTR10EZPF2800 meets all electrical and mechanical requirements of CRCW0805280RFKEB. The additional high voltage feature does not compromise compatibility in standard applications. Use this part when supply of primary alternatives is constrained.

Q: Why is MCR10ERTF2800 marked as discontinued?

A: MCR10ERTF2800 is discontinued at DiGi Electronics but remains electrically equivalent. Discontinuation status reflects distributor inventory decisions, not manufacturer production status. Verify availability through alternative suppliers before specifying this part.

Q: Does package format (Tape & Reel vs. Cut Tape) affect electrical equivalence?

A: No. Package format affects only procurement and assembly logistics. Electrical specifications, performance, and reliability are identical regardless of packaging format. Select based on assembly equipment compatibility and supply chain requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the primary part CRCW0805280RFKEB. All parts are also REACH unaffected and classified under ECCN EAR99.
