RMC1/8K5231FTP Equivalent & Substitute Parts

Part Overview

The RMC1/8K5231FTP is a 5.23 kOhms ±1% 0.25W thick film chip resistor manufactured by Kamaya Inc. in 1206 (3216 Metric) surface mount package format. This component is currently in active product status with 688 pieces available in inventory. Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when specific compliance certifications such as automotive AEC-Q200 qualification are mandated for application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K5231FTP is determined by strict equivalence across the following parameters: resistance value (5.23 kOhms), tolerance (±1%), power rating (0.25W), composition (thick film), package format (1206), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and moisture sensitivity level (MSL 1). All substitute parts listed meet these core electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within the 1206 package specification, packaging format (Tape & Reel versus Cut Tape), and optional certifications (such as AEC-Q200 automotive qualification) do not disqualify substitution but may influence selection based on application requirements and supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

Active Status Parts: RC1206FR-075K23L (YAGEO) and RMCF1206FG5K23 (Stackpole Electronics Inc) maintain active product status and are suitable for new designs and ongoing production. RC1206FR-075K23L includes moisture-resistant features. RMCF1206FG5K23 carries AEC-Q200 automotive qualification and is available in Cut Tape packaging format.

Limited Availability: ERJ-8ENF5231V (Panasonic) is marked "Not For New Designs" and carries AEC-Q200 automotive qualification. MCR18ERTF5231 (Rohm Semiconductor) is discontinued at DiGi Electronics. Both parts remain electrically equivalent but should be considered only when existing inventory must be utilized or when automotive qualification is specifically required and no active alternatives are available.

Compliance Considerations: All substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. All parts carry MSL 1 rating, indicating unlimited moisture sensitivity protection.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF5231V replace RMC1/8K5231FTP in new designs?

A: ERJ-8ENF5231V meets all electrical and mechanical specifications for direct substitution. However, it is marked "Not For New Designs" by the manufacturer. For new designs, RC1206FR-075K23L or RMCF1206FG5K23 are preferred alternatives with active product status.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Both packaging formats contain identical components. Tape & Reel packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape packaging is supplied in smaller quantities on cut segments of carrier tape. RMCF1206FG5K23 is available in Cut Tape format, while other substitutes use Tape & Reel format.

Q: Does AEC-Q200 certification affect electrical performance?

A: AEC-Q200 certification indicates automotive-grade qualification and enhanced reliability testing. It does not alter the electrical specifications (resistance, tolerance, temperature coefficient, power rating). RMCF1206FG5K23 and ERJ-8ENF5231V carry this certification. Selection should be based on application requirements, not performance differences.

Q: Are physical dimension variations within the 1206 package critical?

A: All parts are specified as 1206 (3216 Metric) package. Minor variations in length (0.120" to 0.126"), width (0.061" to 0.063"), and height (0.025" to 0.028") are within standard 1206 package tolerances and do not affect PCB layout compatibility or assembly processes.

Q: Is MCR18ERTF5231 still usable despite discontinuation?

A: MCR18ERTF5231 is electrically and mechanically equivalent and remains suitable for applications where existing inventory is available. Discontinuation status indicates no new production; use is limited to available stock quantities.
