Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW0805210RFKEAC 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 ~ 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

All identified substitute parts meet these core electrical and mechanical requirements. Substitute parts are categorized as follows:

Direct Equivalent (Same Product Status): MCR10ERTF2100 provides direct functional equivalence with identical electrical specifications and packaging, though it is discontinued at DiGi Electronics.

Upgrade Options (Enhanced Specifications): CR0805-FX-2100ELF, KTR10EZPF2100, and RMCF0805FT210R exceed baseline requirements with additional features such as moisture resistance or automotive AEC-Q200 qualification while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Standard Applications: The CRCW0805210RFKEAC remains the primary choice with active production status and adequate inventory. MCR10ERTF2100 provides direct electrical equivalence but is discontinued at DiGi Electronics and should be considered only when existing stock is available.

For Automotive Applications: KTR10EZPF2100 and RMCF0805FT210R are qualified to AEC-Q200 automotive standards and are suitable for automotive-grade circuit designs. Both maintain active production status with substantial inventory levels.

For Enhanced Reliability: CR0805-FX-2100ELF offers moisture-resistant thick film construction with active production status and the highest inventory availability (85,387 pieces), making it suitable for applications requiring additional environmental protection.

All substitute parts maintain full ROHS3 compliance, REACH unaffected status, and EAR99 export classification consistent with the primary part.

Frequently Asked Questions (FAQ)

Q: Can MCR10ERTF2100 be used as a direct replacement for CRCW0805210RFKEAC?

A: Yes. MCR10ERTF2100 meets all electrical and mechanical specifications: 210 Ohms ±1%, 0.125W power rating, 0805 package, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. However, it is discontinued at DiGi Electronics. Verify availability through alternative suppliers before design commitment.

Q: What is the difference between the upgrade options?

A: CR0805-FX-2100ELF adds moisture-resistant construction. KTR10EZPF2100 and RMCF0805FT210R add automotive AEC-Q200 qualification. All three maintain identical core electrical specifications and 0805 package compatibility.

Q: Are there height differences between substitute parts?

A: Yes. CRCW0805210RFKEAC and CR0805-FX-2100ELF have maximum seated height of 0.024" (0.60mm). MCR10ERTF2100, KTR10EZPF2100, and RMCF0805FT210R have maximum seated height of 0.026" (0.65mm). Verify PCB clearance requirements before substitution.

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

A: No. CRCW0805210RFKEAC, CR0805-FX-2100ELF, KTR10EZPF2100, and RMCF0805FT210R are supplied in Tape & Reel (TR) format. MCR10ERTF2100 is supplied in Cut Tape (CT) & Digi-Reel® format. Confirm packaging compatibility with assembly requirements.

Q: Are all parts RoHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes.
