Key Parameters

Substitute Part Grouping Explanation

Substitution of the RMC1/8K18R2FTP is determined by strict equivalence of the following parameters:

Mandatory Matching Parameters:

• Resistance value: 18.2 Ohms
• 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: 1 (Unlimited)
• Number of terminations: 2

All identified substitute parts meet these mandatory parameters. Substitute parts may differ in manufacturer, product status, certifications, and physical dimensions within acceptable tolerances for the 1206 package classification.

Engineering Selection Recommendations

Primary Selection (Active Status, No Automotive Requirement): RC1206FR-0718L (YAGEO) is the preferred substitute when the original RMC1/8K18R2FTP is unavailable. This part maintains Active product status, is ROHS3 compliant, includes moisture-resistant features, and provides equivalent electrical and mechanical specifications.

Secondary Selection (Active Status, No Automotive Requirement): RMCF1206FT18R2 (Stackpole Electronics Inc) is an alternative substitute with Active product status and ROHS3 compliance. This part includes AEC-Q200 automotive qualification, which provides additional reliability assurance even for non-automotive applications.

Conditional Selection (Automotive Applications): When AEC-Q200 automotive qualification is required, RMCF1206FT18R2 (Stackpole) or ERJ-8ENF18R2V (Panasonic) are suitable substitutes. ERJ-8ENF18R2V carries Not For New Designs status; therefore, RMCF1206FT18R2 is preferred for new automotive designs.

Inventory Consideration: RC1206FR-0718R2L (YAGEO) offers the highest inventory availability at 5,100 pieces, followed by RMCF1206FT18R2 (Stackpole) at 3,468 pieces.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF18R2V (Panasonic) be used as a direct substitute for RMC1/8K18R2FTP?

A: ERJ-8ENF18R2V meets all mandatory electrical and mechanical parameters. However, its Not For New Designs product status indicates Panasonic has discontinued active development. For new designs, RC1206FR-0718R2L or RMCF1206FT18R2 are preferred alternatives.

Q: What is the difference between the physical dimensions of these substitute parts?

A: RMC1/8K18R2FTP and RC1206FR-0718R2L share identical length (0.122") and width (0.063"), with maximum seated height of 0.025" (0.65mm). ERJ-8ENF18R2V and RMCF1206FT18R2 have slightly larger dimensions: length 0.126", width 0.063", and maximum seated height 0.028" (0.70mm). All parts conform to the 1206 (3216 Metric) package classification and are mechanically compatible in standard PCB footprints designed for this package.

Q: Are all substitute parts RoHS compliant?

A: RC1206FR-0718R2L, ERJ-8ENF18R2V, and RMCF1206FT18R2 are all ROHS3 compliant. RoHS compliance status for the original RMC1/8K18R2FTP is not specified in the provided data.

Q: Which substitute part should be selected for automotive applications?

A: RMCF1206FT18R2 (Stackpole Electronics Inc) is the recommended choice for automotive applications. It maintains Active product status and carries AEC-Q200 certification. ERJ-8ENF18R2V also holds AEC-Q200 certification but is marked Not For New Designs.

Q: Can these parts be used interchangeably in existing designs?

A: All substitute parts are electrically equivalent and mechanically compatible within the 1206 package specification. Physical dimension variations (up to 0.004" in length and 0.003" in height) are within standard PCB footprint tolerances for 1206 components. Substitution does not require design modification.
