RMC1/8K4873FTP Equivalent & Substitute Parts

Part Overview

The RMC1/8K4873FTP is a 487 kOhms ±1% 0.25W thick film chip resistor manufactured by Kamaya Inc. in 1206 (3216 Metric) surface mount package format. This component is classified as Active product status and is supplied in Tape & Reel packaging with 1055 pieces currently in stock inventory.

Substitute parts are necessary when the primary part becomes unavailable, when design requirements mandate specific certifications such as AEC-Q200 automotive qualification, or when alternative manufacturers' components offer equivalent electrical and mechanical performance within the same package specification.

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K4873FTP is determined by strict equivalence across the following parameters:

Mandatory Matching Parameters:

Resistance value: 487 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 ~ 155°C
Moisture sensitivity level: MSL 1 (Unlimited)
Number of terminations: 2

All substitute parts listed meet these mandatory electrical and mechanical parameters. Variations in physical dimensions (length, width, height) within the 1206 package specification, RoHS compliance status, and optional certifications such as AEC-Q200 do not disqualify substitution but represent additional features or compliance attributes.

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

KTR18EZPF4873 (Rohm Semiconductor) and RMCF1206FT487K (Stackpole Electronics Inc) are recommended as primary substitutes. Both components maintain Active product status, ensuring continued availability and manufacturer support. KTR18EZPF4873 includes AEC-Q200 automotive qualification and high voltage features. RMCF1206FT487K includes AEC-Q200 automotive qualification.

RC1206FR-07487KL (YAGEO) is an Active product substitute with moisture-resistant features and equivalent electrical specifications.

Secondary Substitute (Legacy Status):

ERJ-8ENF4873V (Panasonic Electronic Components) meets all electrical and mechanical parameters but carries Not For New Designs product status. This component is suitable for replacement in existing designs or legacy applications where continued supply is available but not recommended for new product development.

All substitute parts are REACH Unaffected and classified under ECCN EAR99 with identical HTSUS code 8533.21.0030.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF4873V replace RMC1/8K4873FTP in new designs?

A: ERJ-8ENF4873V carries Not For New Designs product status. While it meets all electrical and mechanical parameters, it is not recommended for new product development. Use KTR18EZPF4873, RMCF1206FT487K, or RC1206FR-07487KL for new designs.

Q: What is the difference between the substitute parts?

A: All substitute parts share identical resistance (487 kOhms), tolerance (±1%), power rating (0.25W), package (1206), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Differences exist in manufacturer, optional certifications (AEC-Q200), and specific features (high voltage, moisture resistant). Physical dimensions vary slightly within 1206 package specification.

Q: Are all substitutes RoHS compliant?

A: RC1206FR-07487KL, KTR18EZPF4873, and RMCF1206FT487K are ROHS3 Compliant. RMC1/8K4873FTP and ERJ-8ENF4873V do not specify RoHS status in provided data.

Q: Can I use AEC-Q200 qualified parts in non-automotive applications?

A: Yes. AEC-Q200 qualification represents additional testing and reliability assurance. Parts qualified to AEC-Q200 (KTR18EZPF4873, RMCF1206FT487K, ERJ-8ENF4873V) are suitable for any application requiring the specified electrical and mechanical parameters.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. All listed parts share this rating.

Q: Are physical dimension variations within 1206 package critical?

A: Physical dimensions vary slightly among manufacturers (length 0.122" to 0.126", height 0.025" to 0.028") but remain within 1206 (3216 Metric) package specification. Verify PCB footprint design accommodates maximum stated dimensions for your specific application.
