RMC1/8K4533FTP Equivalent & Substitute Parts

Part Overview

The RMC1/8K4533FTP is a 453 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 with unlimited moisture sensitivity rating (MSL 1). Substitute parts are necessary when primary inventory is unavailable, when design requirements mandate specific manufacturer certifications such as AEC-Q200 automotive qualification, or when alternative sourcing improves supply chain resilience for production environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K4533FTP is determined by strict equivalence across the following parameters: resistance value (453 kOhms), tolerance (±1%), power rating (0.25W), package type (1206), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). All identified substitute parts meet these core electrical and mechanical specifications. Dimensional variations within the 1206 package classification are acceptable per IEC 60603 standards. Substitute parts may include additional certifications (AEC-Q200 automotive qualification) or enhanced features (moisture resistance) that do not conflict with the original specification. Product status differences (Active versus Not For New Designs) are noted for design planning purposes but do not affect electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): RC1206FR-07453KL (YAGEO) and RMCF1206FT453K (Stackpole) are recommended as primary substitutes due to Active product status designation. Both components maintain full electrical equivalence to the RMC1/8K4533FTP across all specified parameters.

Automotive Applications: RMCF1206FT453K (Stackpole) and ERJ-8ENF4533V (Panasonic) include AEC-Q200 automotive qualification. Selection of these parts is required for designs subject to automotive reliability standards.

Enhanced Environmental Performance: RC1206FR-07453KL (YAGEO) includes moisture-resistant construction, providing additional protection in high-humidity operating environments while maintaining electrical equivalence.

Legacy Design Continuation: ERJ-8ENF4533V (Panasonic) carries Not For New Designs status. This part remains electrically equivalent and suitable for sustaining production of existing designs but should not be selected for new product development.

Compliance Consideration: YAGEO RC1206FR-07453KL, Panasonic ERJ-8ENF4533V, and Stackpole RMCF1206FT453K all carry ROHS3 compliance certification. Verify compliance requirements for your specific application before final selection.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF4533V (Panasonic) be used as a direct replacement for RMC1/8K4533FTP?

A: Yes. ERJ-8ENF4533V meets all electrical and mechanical specifications: 453 kOhms ±1%, 0.25W power rating, 1206 package, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. However, its Not For New Designs status indicates it is intended for sustaining production only. For new designs, select RC1206FR-07453KL or RMCF1206FT453K.

Q: What is the difference between the 1206 packages across these parts?

A: All parts use 1206 (3216 Metric) package classification. Minor dimensional variations exist: RMC1/8K4533FTP and RC1206FR-07453KL measure 0.122" L × 0.063" W with 0.025" max height; ERJ-8ENF4533V and RMCF1206FT453K measure 0.126" L × 0.063" W with 0.028" max height. These variations remain within 1206 package tolerance and do not affect PCB footprint compatibility.

Q: Are these parts suitable for automotive applications?

A: RMCF1206FT453K (Stackpole) and ERJ-8ENF4533V (Panasonic) carry AEC-Q200 automotive qualification. RMC1/8K4533FTP and RC1206FR-07453KL do not specify automotive certification. Select AEC-Q200 qualified parts for automotive designs.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All four parts carry MSL 1 rating, eliminating moisture sensitivity as a selection differentiator.

Q: Can I substitute based on availability alone?

A: Substitution is valid only when the replacement part meets all specified electrical parameters (resistance, tolerance, power rating, temperature coefficient, operating range) and package requirements (1206). All listed parts satisfy these criteria. Additional considerations include product status (Active preferred for new designs), compliance certifications (RoHS3, AEC-Q200), and special features (moisture resistance) based on application requirements.
