Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K2210FTP is determined by strict equivalence across the following parameters: resistance value (221 Ohms), tolerance (±1%), power rating (0.25W), composition (thick film), package type (1206), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and moisture sensitivity level (MSL 1). All identified substitute parts meet these core electrical and mechanical requirements. Additional features such as automotive AEC-Q200 certification and moisture resistance are secondary qualifiers that do not disqualify a part from substitution but indicate enhanced application scope.

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-07221RL (YAGEO): This substitute offers active product status with ROHS3 compliance and moisture-resistant thick film composition. Electrical and mechanical parameters are fully equivalent to the main part. Suitable for general-purpose applications where automotive certification is not required.

RMCF1206FT221R (Stackpole Electronics Inc): This substitute maintains active product status with ROHS3 compliance and AEC-Q200 automotive qualification. Electrical specifications are fully equivalent. Recommended for applications requiring automotive-grade reliability and certification.

ERJ-8ENF2210V (Panasonic Electronic Components): This substitute carries AEC-Q200 automotive qualification and ROHS3 compliance but is classified as Not For New Designs. Electrical and mechanical parameters are fully equivalent. Use only in legacy design maintenance or when existing supply chain constraints require this specific part.

KTR18EZPF2210 (Rohm Semiconductor): This substitute maintains active product status with ROHS3 compliance, AEC-Q200 automotive qualification, and high-voltage thick film composition. Electrical specifications are fully equivalent. Recommended for automotive and high-reliability applications requiring active product support.

Frequently Asked Questions (FAQ)

Q: Can RMC1/8K2210FTP be directly replaced with any of these substitute parts?

A: Yes. All substitute parts meet the core electrical and mechanical requirements: 221 Ohm resistance, ±1% tolerance, 0.25W power rating, thick film composition, 1206 package, ±100ppm/°C temperature coefficient, -55°C ~ 155°C operating range, and MSL 1 moisture sensitivity. Direct substitution is electrically and mechanically valid.

Q: What is the difference between parts with and without AEC-Q200 certification?

A: AEC-Q200 certification indicates the part meets automotive industry reliability and qualification standards. Parts with this certification (RMCF1206FT221R, ERJ-8ENF2210V, KTR18EZPF2210) are qualified for automotive applications. Parts without this certification (RMC1/8K2210FTP, RC1206FR-07221RL) are suitable for general-purpose applications. Selection depends on application requirements, not electrical equivalence.

Q: Why is ERJ-8ENF2210V marked as "Not For New Designs"?

A: Product status "Not For New Designs" indicates the manufacturer has discontinued active development and recommends alternative parts for new designs. However, the part remains electrically and mechanically equivalent and may be used in legacy system maintenance or when supply availability is critical.

Q: Are there physical dimension differences between these parts?

A: Minor dimensional variations exist. RMC1/8K2210FTP and RC1206FR-07221RL measure 0.122" L x 0.063" W (3.10mm x 1.60mm) with 0.025" (0.65mm) maximum seated height. RMCF1206FT221R, ERJ-8ENF2210V, and KTR18EZPF2210 measure 0.126" L x 0.063" W (3.20mm x 1.60mm) with 0.028" (0.70mm), 0.028" (0.70mm), and 0.026" (0.65mm) maximum seated heights respectively. These variations are within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: Which substitute part offers the highest inventory availability?

A: RMCF1206FT221R (Stackpole Electronics Inc) offers 429,700 pieces in stock, followed by RC1206FR-07221RL (YAGEO) with 125,869 pieces. Both provide substantial supply security for production requirements.

Q: Can these parts be used interchangeably in automotive applications?

A: Parts with AEC-Q200 certification (RMCF1206FT221R, ERJ-8ENF2210V, KTR18EZPF2210) are qualified for automotive use. Parts without this certification should not be used in automotive applications unless design specifications explicitly permit non-certified components.
