Substitute Part Grouping Explanation

Substitution eligibility for the CRCW0805324RFKEAC is determined by strict matching of the following parameters: resistance value (324 Ohms), tolerance (±1%), power rating (0.125W), package type (0805), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). All identified substitute parts meet these core electrical and mechanical requirements. Substitute parts are categorized as direct equivalents or upgrades based on product status and additional features, not on performance superiority.

Engineering Selection Recommendations

MCR10ERTF3240 (Rohm Semiconductor) is a direct electrical equivalent with identical core specifications. However, this part is discontinued at DiGi Electronics, limiting long-term availability for production use.

CR0805-FX-3240ELF (Bourns Inc.) is an active substitute with moisture-resistant thick film composition. This part maintains all core electrical parameters and offers enhanced environmental protection. It is suitable for applications requiring moisture resistance without additional qualification requirements.

KTR10EZPF3240 (Rohm Semiconductor) is an active substitute with automotive AEC-Q200 qualification and high voltage features. This part is appropriate for automotive applications or systems requiring AEC-Q200 compliance. All core electrical and mechanical parameters remain equivalent to the primary part.

Selection should prioritize active products (CR0805-FX-3240ELF or KTR10EZPF3240) for new designs. The choice between these two depends on application requirements: use CR0805-FX-3240ELF for general industrial applications requiring moisture resistance, or KTR10EZPF3240 for automotive or high-voltage applications.

Frequently Asked Questions (FAQ)

Q: Can MCR10ERTF3240 be used as a direct replacement for CRCW0805324RFKEAC?

A: Yes, MCR10ERTF3240 meets all electrical and mechanical substitution criteria. However, this part is discontinued at DiGi Electronics, making it unsuitable for new production designs requiring long-term component availability.

Q: What is the difference between CR0805-FX-3240ELF and KTR10EZPF3240?

A: Both parts are electrically equivalent to CRCW0805324RFKEAC. CR0805-FX-3240ELF features moisture-resistant thick film composition for enhanced environmental protection. KTR10EZPF3240 includes automotive AEC-Q200 qualification and high voltage features for automotive and demanding applications. Select based on application requirements.

Q: Are there height differences between substitute parts?

A: CRCW0805324RFKEAC and CR0805-FX-3240ELF have a maximum seated height of 0.024" (0.60mm). MCR10ERTF3240 and KTR10EZPF3240 have a maximum seated height of 0.026" (0.65mm). This 0.002" (0.05mm) difference is within standard PCB assembly tolerances for 0805 packages and does not affect interchangeability.

Q: Do all substitute parts have the same packaging options?

A: CRCW0805324RFKEAC is supplied in Tape & Reel (TR) packaging. MCR10ERTF3240 is supplied in Cut Tape (CT) & Digi-Reel® packaging. CR0805-FX-3240ELF and KTR10EZPF3240 are supplied in Tape & Reel (TR) packaging. Packaging format should be verified against procurement requirements.

Q: Are all parts RoHS3 compliant?

A: Yes, CRCW0805324RFKEAC, MCR10ERTF3240, CR0805-FX-3240ELF, and KTR10EZPF3240 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).
