Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW0805430RFKEAC is determined by strict equivalence across the following parameters: resistance value (430 Ohms), tolerance (±1%), power rating (0.125W), package type (0805 2012 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

All identified substitute parts meet these core electrical and mechanical requirements. Substitute parts are grouped into two categories: direct equivalents with identical specifications and upgrade options that retain all core parameters while adding enhanced features such as automotive AEC-Q200 qualification or moisture resistance.

KTR10EZPF4300 (Rohm Semiconductor) is an active production part with automotive AEC-Q200 qualification and high voltage rating. This upgrade option is suitable for automotive applications and high-reliability designs. Inventory availability is 7,008 pieces.

RMCF0805FT430R (Stackpole Electronics Inc) is an active production part with automotive AEC-Q200 qualification. This upgrade option is suitable for automotive applications requiring AEC-Q200 compliance. Inventory availability is 12,028 pieces.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 classification identical to the primary part.

Frequently Asked Questions (FAQ)

Q: Can MCR10ERTF4300 be used as a direct replacement for CRCW0805430RFKEAC? A: Yes, MCR10ERTF4300 meets all electrical and mechanical specifications. However, this part is discontinued at DiGi Electronics. Verify alternative supply availability before design implementation. The primary difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel).

Q: What is the difference between the standard CRCW0805430RFKEAC and CR0805-FX-4300ELF? A: Both parts are electrically identical with matching resistance, tolerance, power rating, and temperature specifications. CR0805-FX-4300ELF adds moisture-resistant composition and is in active production with significantly higher inventory availability.

Q: Are KTR10EZPF4300 and RMCF0805FT430R suitable for non-automotive applications? A: Yes. Both parts meet all core electrical and mechanical requirements for the CRCW0805430RFKEAC. Automotive AEC-Q200 qualification and high voltage rating represent enhanced capabilities that do not restrict use in general-purpose applications.

Q: Do all substitute parts have the same package dimensions? A: All parts use the 0805 (2012 Metric) package. Physical dimensions are 0.079" L x 0.049" W (2.00mm x 1.25mm). Maximum seated height varies slightly: CRCW0805430RFKEAC and CR0805-FX-4300ELF are 0.024" (0.60mm), while MCR10ERTF4300, KTR10EZPF4300, and RMCF0805FT430R are 0.026" (0.65mm). Verify PCB layout clearance for height-sensitive applications.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, matching the compliance status of CRCW0805430RFKEAC.
