KTR18EZPJ161 Equivalent & Substitute Parts

Part Overview

The KTR18EZPJ161 is a 160 Ohms ±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 886 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design requirements demand higher tolerance specifications, or when alternative manufacturers' components are preferred for supply chain diversification and cost optimization.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Direct Substitutes (Identical Specifications): Parts that match all critical parameters: 160 Ohms resistance, ±5% tolerance, 0.25W power rating, 1206 package, thick film composition, -55°C to 155°C operating range, and AEC-Q200 automotive rating. These parts are electrically and mechanically interchangeable without design modification.

Upgrade Substitutes (Enhanced Tolerance): Parts that maintain 160 Ohms resistance, 0.25W power rating, 1206 package, and -55°C to 155°C operating range but feature ±1% tolerance instead of ±5%. These parts provide improved accuracy and tighter resistance control. Temperature coefficient improves to ±100ppm/°C. Upgrade substitutes are backward compatible with designs specified for ±5% tolerance.

Similar Parts (Matching Core Specifications): Parts that maintain all critical electrical specifications but may differ in secondary characteristics such as moisture resistance features or specific manufacturer series designation. These remain functionally equivalent within the defined parameter set.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): CRCW1206160RJNEA (Vishay Dale) and RMCF1206JT160R (Stackpole Electronics Inc) are recommended as primary direct substitutes. Both maintain AEC-Q200 automotive qualification, active production status, and identical electrical parameters. CRCW1206160RJNEA offers the highest inventory availability at 20,157 units.

For Automotive Applications Requiring AEC-Q200: When AEC-Q200 compliance is mandatory, select from: KTR18EZPJ161 (primary), CRCW1206160RJNEA, RMCF1206JT160R, or RMCF1206FT160R (upgrade option with ±1% tolerance). All four parts carry AEC-Q200 certification and are suitable for automotive environments.

For Enhanced Tolerance Requirements: RMCF1206FT160R (Stackpole Electronics Inc) provides ±1% tolerance with AEC-Q200 rating and active production status. This upgrade option reduces tolerance band from ±5% to ±1% while maintaining automotive qualification.

For Non-Automotive Applications: CR1206-FX-1600ELF (Bourns Inc.) or RC1206FR-07160RL (YAGEO) are suitable alternatives with ±1% tolerance and moisture-resistant features. These parts are active in production but do not carry AEC-Q200 certification.

Parts to Avoid for New Designs: ERJ-8GEYJ161V and ERJ-8ENF1600V (Panasonic) are marked "Not For New Designs." MCR18ERTF1600 (Rohm Semiconductor) is discontinued at DiGi Electronics and should not be selected for new applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute KTR18EZPJ161 with CRCW1206160RJNEA? A: Yes. Both parts are electrically and mechanically identical with 160 Ohms ±5% resistance, 0.25W power rating, 1206 package, and AEC-Q200 automotive qualification. Direct substitution is valid without design modification.

Q: What is the difference between ±5% and ±1% tolerance parts? A: Tolerance defines the acceptable resistance variation from the nominal 160 Ohm value. ±5% tolerance allows variation between 152 and 168 Ohms. ±1% tolerance restricts variation to 158.4 and 161.6 Ohms. ±1% parts provide tighter resistance control and are suitable for precision applications. ±1% parts are backward compatible with ±5% specifications.

Q: Are all substitute parts in the same 1206 package? A: Yes. All listed parts use the 1206 (3216 Metric) package with identical footprint dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm). Physical dimensions are consistent across all substitutes, ensuring PCB compatibility.

Q: Which substitute has the best inventory availability? A: CRCW1206160RJNEA (Vishay Dale) has the highest inventory at 20,157 units in stock, followed by RC1206FR-07160RL (YAGEO) at 95,796 units for the ±1% tolerance variant.

Q: Do all parts meet RoHS3 compliance? A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: What is the operating temperature range for all substitutes? A: All parts operate across -55°C to 155°C, providing consistent thermal performance across the entire substitute list.

Q: Can I use ERJ-8GEYJ161V in a new design? A: No. This part is marked "Not For New Designs" by the manufacturer. Select from active production alternatives such as CRCW1206160RJNEA, RMCF1206JT160R, or RMCF1206FT160R instead.

Q: What is the difference between AEC-Q200 and non-AEC-Q200 parts? A: AEC-Q200 certification indicates the part meets automotive industry reliability and quality standards. For automotive applications, select only AEC-Q200 qualified parts: KTR18EZPJ161, CRCW1206160RJNEA, RMCF1206JT160R, RMCF1206FT160R, or ERJ-8ENF1600V.
