Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW0805210RFKEBC is determined by strict equivalence across the following parameters: resistance value (210 Ohms), tolerance (±1%), power rating (0.125W), package type (0805), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

All identified substitute parts meet these core electrical and mechanical requirements. Substitute parts are grouped by product status and additional features:

• Direct Equivalent (Discontinued): MCR10ERTF2100 by Rohm Semiconductor maintains identical electrical specifications but is discontinued at DiGi Electronics.
• Enhanced Specifications (Active): CR0805-FX-2100ELF, KTR10EZPF2100, and RMCF0805FT210R add features such as moisture resistance or automotive AEC-Q200 qualification while maintaining core parameter equivalence.

Parameter Comparison

Engineering Selection Recommendations

For standard applications requiring a 210 Ohm ±1% 0.125W 0805 resistor, the CRCW0805210RFKEBC remains the primary choice with active product status and adequate inventory.

When the primary part is unavailable, MCR10ERTF2100 provides direct electrical equivalence, though its discontinued status limits long-term availability.

For applications requiring enhanced reliability or specific environmental conditions:

• CR0805-FX-2100ELF is selected when moisture resistance is a design requirement. This part maintains identical height and electrical specifications while adding moisture-resistant composition.
• KTR10EZPF2100 is selected for automotive applications requiring AEC-Q200 qualification and high voltage performance. This part carries automotive certification and is actively produced.
• RMCF0805FT210R is selected for automotive applications requiring AEC-Q200 qualification. This part is actively produced with strong inventory availability.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 classification, ensuring regulatory equivalence with the primary part.

Frequently Asked Questions (FAQ)

Q: Can MCR10ERTF2100 be used as a direct replacement for CRCW0805210RFKEBC?

A: Yes, MCR10ERTF2100 meets all electrical and mechanical specifications for direct substitution. However, this part is discontinued at DiGi Electronics, limiting future availability. It is suitable for immediate replacement but not recommended for new designs requiring long-term supply assurance.

Q: What is the difference between CR0805-FX-2100ELF and the primary part?

A: CR0805-FX-2100ELF is electrically and mechanically equivalent to CRCW0805210RFKEBC with the addition of moisture-resistant composition. Both parts have identical height (0.024" maximum) and all electrical parameters. The moisture-resistant feature provides enhanced performance in humid or corrosive environments.

Q: Are KTR10EZPF2100 and RMCF0805FT210R suitable for automotive applications?

A: Yes, both parts carry AEC-Q200 automotive qualification. KTR10EZPF2100 additionally specifies high voltage performance. Both are actively produced with strong inventory levels and are suitable for automotive designs requiring qualified components.

Q: Does the 0.002" height difference between substitute parts affect PCB layout?

A: The maximum height difference between parts is 0.002" (0.05mm), occurring between CRCW0805210RFKEBC / CR0805-FX-2100ELF (0.024") and MCR10ERTF2100 / KTR10EZPF2100 / RMCF0805FT210R (0.026"). This difference is negligible for standard PCB assembly and does not affect component placement or clearance in typical designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory equivalence with the primary part CRCW0805210RFKEBC.
