Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K6342FTP is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 63.4 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: 1 (Unlimited)

All substitute parts listed maintain identical electrical specifications and thermal characteristics. Dimensional variations within supplier device package specifications (1206) are acceptable. Substitute parts may include additional features such as automotive AEC-Q200 certification or moisture-resistant construction, which represent enhancements rather than deviations from the base specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status, Standard Applications): RC1206FR-0763K4L (YAGEO) and RMCF1206FG63K4 or RMCF1206FT63K4 (Stackpole) are recommended as primary substitutes. All three maintain Active product status, ensuring long-term availability and continued manufacturing support. YAGEO RC1206FR-0763K4L includes moisture-resistant construction. Both Stackpole variants (RMCF1206FG63K4 and RMCF1206FT63K4) carry AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability.

Secondary Selection (Automotive Applications): RMCF1206FG63K4 and RMCF1206FT63K4 are specified for designs requiring AEC-Q200 certification. Both parts are Active status with identical electrical and thermal specifications to the main part.

Legacy Applications (Not For New Designs): ERJ-8ENF6342V (Panasonic) is classified as Not For New Designs. This part is electrically equivalent and carries AEC-Q200 certification but should not be selected for new product development due to its product status designation.

All substitute parts are ROHS3 compliant where specified, supporting environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF6342V replace RMC1/8K6342FTP in new designs? A: ERJ-8ENF6342V is electrically and mechanically equivalent but carries a "Not For New Designs" product status. For new product development, select RC1206FR-0763K4L, RMCF1206FG63K4, or RMCF1206FT63K4 instead.

Q: What is the difference between RMCF1206FG63K4 and RMCF1206FT63K4? A: Both parts are manufactured by Stackpole Electronics Inc. with identical electrical specifications, resistance value, tolerance, power rating, and package. Both carry AEC-Q200 automotive certification. The difference lies in manufacturing code designation (FG vs. FT), which does not affect electrical or mechanical compatibility.

Q: Are dimensional variations between substitute parts significant? A: All parts use the 1206 (3216 Metric) package. Minor dimensional variations exist within supplier specifications (length 0.122" to 0.126", height 0.025" to 0.028"). These variations are within standard PCB design tolerances and do not affect board-level compatibility.

Q: Which substitute part offers the best long-term availability? A: RC1206FR-0763K4L (YAGEO), RMCF1206FG63K4, and RMCF1206FT63K4 (Stackpole) all maintain Active product status, indicating ongoing manufacturing and supply support.

Q: Do substitute parts require different soldering profiles? A: All substitute parts use identical 1206 package specifications and Tape & Reel packaging. Standard SMD soldering processes apply uniformly across all parts listed.

Q: Is AEC-Q200 certification required for my application? A: AEC-Q200 certification is required only for automotive applications. For non-automotive applications, RC1206FR-0763K4L provides an equivalent alternative without automotive qualification overhead.
