RMC1/8K4753FTP Equivalent & Substitute Parts

Part Overview

The RMC1/8K4753FTP is a 475 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 power dissipation characteristics.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements mandate specific certifications such as automotive AEC-Q200 qualification or enhanced moisture resistance features. All substitute parts listed maintain electrical and mechanical compatibility within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K4753FTP is determined by strict adherence to the following core parameters:

Mandatory Matching Parameters:

• Resistance value: 475 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture sensitivity level: 1 (Unlimited)
• Termination count: 2

All five substitute parts listed (ERJ-8ENF4753V, KTR18EZPF4753, RC1206FR-07475KL, RMCF1206FG475K, RMCF1206FT475K) meet these mandatory electrical and mechanical parameters. Variations in physical dimensions (length and height) within the 1206 package specification and differences in product certifications (such as AEC-Q200 automotive qualification) do not disqualify substitution but represent additional design considerations based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status, No Certifications Required): RC1206FR-07475KL (YAGEO) is the preferred substitute when supply of the RMC1/8K4753FTP is constrained. This part maintains Active product status, offers the highest inventory availability (117,823 pcs), and includes moisture-resistant features. ROHS3 compliance is provided.

Automotive Applications (AEC-Q200 Required): KTR18EZPF4753 (Rohm Semiconductor) is specified for automotive or high-reliability applications requiring AEC-Q200 qualification. This part includes High Voltage designation and maintains Active product status with 9,488 pcs in stock.

Alternative Automotive Options: RMCF1206FG475K and RMCF1206FT475K (both Stackpole Electronics Inc) provide AEC-Q200 certification with Active product status. RMCF1206FG475K offers higher inventory (8,069 pcs) compared to RMCF1206FT475K (1,046 pcs).

Legacy Design Consideration: ERJ-8ENF4753V (Panasonic Electronic Components) carries "Not For New Designs" status and should be used only when existing designs mandate this specific part number. High inventory availability (21,826 pcs) does not override this product status designation.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF4753V be used as a direct replacement for RMC1/8K4753FTP?

A: Electrical and mechanical parameters are identical. However, ERJ-8ENF4753V carries "Not For New Designs" product status. Use this part only for legacy design maintenance or when design documentation explicitly specifies this manufacturer part number.

Q: What is the difference between RMCF1206FG475K and RMCF1206FT475K?

A: Both parts are manufactured by Stackpole Electronics Inc with identical electrical specifications and AEC-Q200 certification. Physical dimensions differ slightly (height: 0.028" vs 0.028" maximum). Inventory levels differ (8,069 pcs vs 1,046 pcs). Selection should be based on availability and PCB assembly process requirements.

Q: Is KTR18EZPF4753 suitable for non-automotive applications?

A: Yes. KTR18EZPF4753 meets all electrical and mechanical parameters required for the RMC1/8K4753FTP. The AEC-Q200 automotive certification and High Voltage designation represent additional qualifications that do not restrict use in general-purpose applications. This part is Active status with 9,488 pcs available.

Q: Does package size variation affect PCB layout compatibility?

A: All substitute parts use the 1206 (3216 Metric) package. Physical dimension variations (length: 0.122" to 0.126", height: 0.025" to 0.028") fall within standard 1206 package tolerances and do not require PCB layout modification. Verify with your PCB design tool if tight spacing constraints exist.

Q: Are all substitute parts ROHS3 compliant?

A: All five substitute parts listed carry ROHS3 Compliant status. The RMC1/8K4753FTP does not specify RoHS status in the provided data. If RoHS compliance is a design requirement, all listed substitutes satisfy this criterion.

Q: What is the significance of Moisture Sensitivity Level 1 (Unlimited)?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. Storage, handling, and reflow processes do not require special moisture control measures. All parts listed, including the primary RMC1/8K4753FTP, carry this rating.

Q: Can I use RC1206FR-07475KL in high-temperature applications?

A: RC1206FR-07475KL operates across the full -55°C to 155°C temperature range specified for all parts in this comparison. The ±100ppm/°C temperature coefficient applies across this entire range. Application-specific thermal analysis is required to confirm suitability for specific operating conditions.
