KTR18EZPJ751 Equivalent & Substitute Parts

Part Overview

The KTR18EZPJ751 is a 750 Ohm ±5% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Rohm Semiconductor. This automotive-grade component meets AEC-Q200 specifications and operates across -55°C to 155°C. The part is currently active in production with 1107 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 offer improved availability or performance characteristics while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the KTR18EZPJ751 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

Resistance value: 750 Ohms (exact match required)
Package type: 1206 (3216 Metric) form factor
Power rating: 0.25W minimum
Operating temperature range: -55°C to 155°C minimum
Composition: Thick film construction
RoHS3 compliance and MSL 1 rating

Allowable Variation Parameters:

Tolerance: ±5% or tighter (±1% acceptable as upgrade)
Temperature coefficient: ±200ppm/°C or better
Automotive certification: AEC-Q200 preferred but not mandatory for all applications
Manufacturer: Multiple qualified sources available

Substitute parts are grouped into three categories: direct equivalents (identical specifications), upgrades (improved tolerance or temperature coefficient), and similar alternatives (different power ratings or feature sets).

Engineering Selection Recommendations

Direct Equivalents (Preferred for Direct Replacement):

CRCW1206750RJNEA (Vishay Dale) and RMCF1206JT750R (Stackpole Electronics) are direct functional equivalents with identical electrical specifications, AEC-Q200 certification, and active production status. Both offer superior inventory availability compared to the primary part.

Tolerance Upgrades (±1% Specification):

KTR18EZPF7500 (Rohm Semiconductor), RC1206FR-07750RL (YAGEO), CR1206-FX-7500ELF (Bourns Inc.), and ERJ-8ENF7500V (Panasonic) provide tighter tolerance (±1%) and improved temperature coefficient (±100ppm/°C). These are suitable when design margins require higher precision. KTR18EZPF7500 maintains AEC-Q200 compliance; others do not.

Alternative Specifications:

ESR18EZPJ751 (Rohm Semiconductor) offers doubled power rating (0.5W) in identical package with matching tolerance and temperature coefficient. This part is suitable only when higher power dissipation capability is required.

MCR18ERTJ751 (Rohm Semiconductor) is discontinued at DiGi Electronics and should not be selected for new designs despite matching electrical specifications.

ERJ-8GEYJ751V (Panasonic) carries "Not For New Designs" status and should be avoided for new applications despite high inventory availability.

Compliance Considerations:

All recommended parts maintain ROHS3 compliance and MSL 1 rating. For automotive applications requiring AEC-Q200 certification, select from: KTR18EZPJ751, KTR18EZPF7500, CRCW1206750RJNEA, ERJ-8GEYJ751V, RMCF1206JT750R, ESR18EZPJ751, or ERJ-8ENF7500V.

Frequently Asked Questions (FAQ)

Q: Can I substitute a ±1% tolerance part for the ±5% specification?

A: Yes. Tighter tolerance is a compatible upgrade. Parts with ±1% tolerance (KTR18EZPF7500, RC1206FR-07750RL, CR1206-FX-7500ELF, ERJ-8ENF7500V) will function in any circuit designed for ±5% tolerance. The actual resistance value will be closer to the nominal 750 Ohm specification.

Q: What is the difference between direct equivalents and upgrades?

A: Direct equivalents (CRCW1206750RJNEA, RMCF1206JT750R, RC1206JR-07750RL) match all electrical specifications of the KTR18EZPJ751. Upgrades (KTR18EZPF7500, RC1206FR-07750RL, CR1206-FX-7500ELF, ERJ-8ENF7500V) improve tolerance or temperature coefficient performance while maintaining the same resistance, power rating, and package.

Q: Can I use the ESR18EZPJ751 as a substitute?

A: The ESR18EZPJ751 is mechanically and electrically compatible in the 1206 package with matching resistance and tolerance. However, it provides 0.5W power rating instead of 0.25W. Use this part only if your circuit can accommodate the higher power rating or if power dissipation requirements exceed 0.25W.

Q: Why are some parts marked "Not For New Designs"?

A: ERJ-8GEYJ751V and ERJ-8ENF7500V carry this status from the manufacturer, indicating these parts are in end-of-life phase. While currently in stock, they should not be selected for new product designs. Active alternatives are available from multiple manufacturers.

Q: Does package size vary between substitutes?

A: All listed substitutes use the 1206 (3216 Metric) package. Physical dimensions are consistent across manufacturers with minor height variations (0.024" to 0.030" seated height). These variations are within standard PCB assembly tolerances and do not affect interchangeability.

Q: Which substitute offers the best availability?

A: RMCF1206JT750R (Stackpole Electronics) has the highest inventory at 357,869 units. RC1206FR-07750RL (YAGEO) offers 171,036 units with ±1% tolerance upgrade. Both are active production parts with reliable supply.

Q: Are all substitutes AEC-Q200 compliant?

A: No. AEC-Q200 certification is present in KTR18EZPJ751, KTR18EZPF7500, CRCW1206750RJNEA, ERJ-8GEYJ751V, RMCF1206JT750R, ESR18EZPJ751, and ERJ-8ENF7500V. For automotive applications requiring this certification, select from this list.

Q: What is the temperature coefficient difference between ±200ppm/°C and ±100ppm/°C?

A: Temperature coefficient defines resistance change per degree Celsius. ±100ppm/°C (upgrade parts) provides half the drift rate of ±200ppm/°C (standard parts). For circuits with tight tolerance requirements across temperature ranges, the ±100ppm/°C specification is superior.
