KTR18EZPJ565 Equivalent & Substitute Parts

Part Overview

The KTR18EZPJ565 is a 5.6 MOhms ±5% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Rohm Semiconductor. This component is rated for automotive applications under AEC-Q200 and operates across -55°C to 155°C. The part is currently active in production with 903 units in stock. Equivalent and substitute parts are necessary to address supply chain continuity, packaging format preferences, tolerance requirements, or design optimization needs.

Substitute Part Grouping Explanation

Substitution eligibility for the KTR18EZPJ565 is determined by the following critical parameters: resistance value (5.6 MOhms), package format (1206), power rating (0.25W), composition (thick film), and operating temperature range (-55°C to 155°C). All listed substitute parts maintain these core specifications.

Substitute parts are grouped into three categories:

Direct Equivalents maintain identical electrical specifications (5.6 MOhms ±5%, 0.25W) and packaging. These parts differ only in manufacturer and packaging format (tape & reel versus cut tape).

Similar Equivalents maintain core electrical specifications but may have minor dimensional variations or different product status. The MCR18ERTJ565 is discontinued at DiGi Electronics but remains functionally equivalent.

Upgraded Alternatives offer improved tolerance (±1% instead of ±5%) or enhanced features (moisture resistance) while maintaining the same resistance, power rating, and package. These parts are suitable when design margins permit tighter tolerance specifications.

Engineering Selection Recommendations

For direct replacement with active product status and AEC-Q200 compliance: RMCF1206JT5M60 (Stackpole Electronics Inc) is the primary equivalent. It maintains identical electrical specifications, automotive qualification, and tape & reel packaging. This part has 8021 units in stock.

For automotive applications requiring tighter tolerance: RMCF1206FT5M60 (Stackpole Electronics Inc) provides ±1% tolerance while retaining AEC-Q200 rating and identical temperature coefficient. This upgrade is suitable when circuit design requires improved accuracy. 6359 units are available.

For non-automotive applications with tolerance flexibility: RC1206JR-075M6L (YAGEO) maintains ±5% tolerance and active product status with 9367 units in stock. This part lacks AEC-Q200 rating but is suitable for general industrial applications.

For applications requiring enhanced tolerance and moisture resistance: RC1206FR-075M6L (YAGEO) offers ±1% tolerance with moisture-resistant construction. This part is active with 2100 units available but does not carry AEC-Q200 certification.

For supply chain continuity only: MCR18ERTJ565 (Rohm Semiconductor) is functionally equivalent but discontinued at DiGi Electronics. Use only if existing inventory is available and long-term supply is not required.

Frequently Asked Questions (FAQ)

Q: Can RMCF1206JT5M60 replace KTR18EZPJ565 in automotive applications? A: Yes. Both parts maintain 5.6 MOhms ±5%, 0.25W, 1206 package, and AEC-Q200 automotive qualification. Electrical and mechanical compatibility is confirmed.

Q: What is the difference between ±5% and ±1% tolerance parts? A: Tolerance defines the maximum deviation from the nominal 5.6 MOhms value. ±5% allows ±280 kOhms deviation; ±1% allows ±56 kOhms. Tighter tolerance (±1%) is required for precision circuits but is not necessary for general applications.

Q: Are YAGEO parts suitable for automotive designs? A: RC1206FR-075M6L and RC1206JR-075M6L lack AEC-Q200 certification. They are suitable for non-automotive or non-critical applications. For automotive designs, use Rohm or Stackpole parts with AEC-Q200 rating.

Q: What is the impact of different temperature coefficients? A: KTR18EZPJ565 and RMCF series have ±200ppm/°C; YAGEO RC series have ±100ppm/°C. Lower temperature coefficient indicates better stability across temperature extremes. For applications with wide temperature swings, lower coefficient is preferable.

Q: Can I use cut tape packaging instead of tape & reel? A: Packaging format (cut tape versus tape & reel) affects handling and automation compatibility, not electrical performance. Verify your assembly process requirements before substituting packaging formats.

Q: Is MCR18ERTJ565 still available? A: MCR18ERTJ565 is discontinued at DiGi Electronics but 5693 units remain in stock. Use only if immediate supply is available and long-term availability is not required for production designs.
