RMC1/8K5233FTP Equivalent & Substitute Parts

Part Overview

The RMC1/8K5233FTP is a 523 kOhms ±1% 0.25W thick film chip resistor manufactured by Kamaya Inc. in 1206 (3216 Metric) surface mount package. This component is classified as Active product status and is suitable for general-purpose resistive applications requiring standard tolerance and temperature stability across industrial temperature ranges.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design specifications allow for equivalent components from alternative manufacturers that meet identical electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K5233FTP is determined by strict equivalence across the following parameters:

Critical Electrical Parameters:

• Resistance value: 523 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Critical Mechanical Parameters:

• Package / Case: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)

Regulatory & Compliance Parameters:

• REACH Status: REACH Unaffected (all substitutes must match)
• ECCN: EAR99 (all substitutes must match)
• HTSUS: 8533.21.0030 (all substitutes must match)

All identified substitute parts meet these criteria. Additional features such as automotive AEC-Q200 qualification or moisture resistance represent enhanced specifications that do not disqualify a part from substitution but indicate expanded application suitability.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status, Standard Application): RC1206FR-07523KL (YAGEO) is the preferred substitute for new designs and ongoing production. This part maintains Active product status, carries ROHS3 compliance certification, and includes moisture-resistant features. Dimensional specifications (0.122" L x 0.063" W, 0.026" max height) are equivalent to the primary part.

Alternative Selection (Automotive Applications): RMCF1206FT523K (Stackpole Electronics Inc) is suitable when AEC-Q200 automotive qualification is required. This part carries Active product status and ROHS3 compliance. Dimensional specifications (0.126" L x 0.063" W, 0.028" max height) remain within acceptable mechanical tolerances for 1206 package footprints.

Secondary Alternative (Automotive Applications): ERJ-8ENF5233V (Panasonic Electronic Components) provides AEC-Q200 automotive qualification but carries Not For New Designs product status. This part is suitable only for sustaining production of existing designs or legacy system maintenance. Dimensional specifications (0.126" L x 0.063" W, 0.028" max height) are equivalent to RMCF1206FT523K.

All three substitute parts are electrically and mechanically equivalent to RMC1/8K5233FTP and satisfy identical regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF5233V be used in new product designs? A: No. ERJ-8ENF5233V carries Not For New Designs product status. For new designs, use RC1206FR-07523KL or RMCF1206FT523K.

Q: What is the difference between standard and automotive-qualified versions? A: Automotive-qualified versions (ERJ-8ENF5233V and RMCF1206FT523K) carry AEC-Q200 certification, indicating compliance with automotive reliability and quality standards. Standard versions (RMC1/8K5233FTP and RC1206FR-07523KL) do not carry this certification. Both types meet identical electrical and mechanical specifications for the 523 kOhms ±1% 0.25W 1206 resistor.

Q: Are there dimensional differences between substitute parts? A: Minor dimensional variations exist within 1206 package specifications. RMC1/8K5233FTP and RC1206FR-07523KL measure 0.122" L x 0.063" W with 0.025-0.026" max height. ERJ-8ENF5233V and RMCF1206FT523K measure 0.126" L x 0.063" W with 0.028" max height. These variations remain within standard 1206 (3216 Metric) package tolerances and do not affect PCB footprint compatibility.

Q: What does ROHS3 compliance indicate? A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead and other hazardous materials. RC1206FR-07523KL, ERJ-8ENF5233V, and RMCF1206FT523K all carry ROHS3 certification.

Q: Can these parts be used interchangeably in existing designs? A: Yes. All substitute parts meet identical electrical parameters (523 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C), identical package specifications (1206 / 3216 Metric), and identical regulatory requirements (REACH Unaffected, EAR99, HTSUS 8533.21.0030). Mechanical dimensions remain within standard package tolerances.

Q: Which substitute offers the best long-term availability? A: RC1206FR-07523KL (YAGEO) maintains Active product status with 6166 pieces in stock. RMCF1206FT523K (Stackpole) also maintains Active status with 3950 pieces in stock. Both are suitable for long-term production commitments.
