Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the KTR10EZPJ300 are classified based on the following criteria:

Direct Equivalents maintain all electrical parameters: 30 Ohms resistance, ±5% tolerance, 0.125W power rating, 0805 package, -55°C to 155°C operating range, and AEC-Q200 automotive qualification. These parts differ only in manufacturer and packaging format (Tape & Reel versus Cut Tape).

Tolerance Upgrades provide ±1% tolerance instead of ±5%, reducing resistive variance while maintaining identical resistance value, power rating, package, and operating temperature range. These parts feature improved temperature coefficient (±100ppm/°C versus ±200ppm/°C) and are suitable for applications requiring tighter tolerance control.

Packaging Variants offer alternative delivery formats (Cut Tape & Digi-Reel® versus Tape & Reel) while preserving all electrical specifications and mechanical dimensions.

All substitute parts comply with ROHS3, maintain MSL 1 rating, and operate within the specified temperature range. Substitution eligibility is determined by matching resistance value, power rating, package type, and operating temperature requirements.

Parameter Comparison

Engineering Selection Recommendations

For AEC-Q200 Automotive Applications with ±5% Tolerance Requirements: ERJ-6GEYJ300V (Panasonic), CRCW080530R0JNEA (Vishay Dale), and RMCF0805JT30R0 (Stackpole Electronics Inc) are direct equivalents to KTR10EZPJ300. All three maintain automotive qualification, identical electrical specifications, and active production status. Selection among these options is based on packaging availability and supply chain considerations.

For Improved Tolerance (±1%) with AEC-Q200 Qualification: ERJ-6ENF30R0V (Panasonic) and RMCF0805FT30R0 (Stackpole Electronics Inc) provide ±1% tolerance with AEC-Q200 rating and active product status. These parts feature reduced temperature coefficient (±100ppm/°C) and are suitable for precision circuit applications requiring tighter resistive control.

For Non-Automotive Applications with ±5% Tolerance: RC0805JR-0730RL (YAGEO) is functionally equivalent but lacks AEC-Q200 certification. This part is appropriate for general-purpose applications where automotive qualification is not required.

For Non-Automotive Applications with ±1% Tolerance: RC0805FR-0730RL (YAGEO) offers ±1% tolerance in Cut Tape & Digi-Reel® packaging. This option is suitable for precision applications outside automotive environments.

Avoid: MCR10ERTF30R0 is discontinued at DiGi Electronics and should not be selected for new designs despite its ±1% tolerance specification.

Frequently Asked Questions (FAQ)

Q: Can I substitute KTR10EZPJ300 with ERJ-6GEYJ300V in an automotive circuit? A: Yes. Both parts share identical electrical specifications (30 Ω ±5%, 0.125W), operate across -55°C to 155°C, and meet AEC-Q200 automotive qualification. The substitution is direct.

Q: What is the difference between ±5% and ±1% tolerance parts? A: Tolerance defines the maximum deviation from the nominal 30 Ohm resistance value. ±5% tolerance allows deviation up to ±1.5 Ohms; ±1% tolerance restricts deviation to ±0.3 Ohms. Applications requiring precise resistive values benefit from ±1% parts. The ±1% variants also feature improved temperature coefficient (±100ppm/°C versus ±200ppm/°C), resulting in better stability across temperature extremes.

Q: Are Tape & Reel and Cut Tape & Digi-Reel® packages interchangeable? A: Both packaging formats contain identical components in 0805 (2012 Metric) package. The difference is in delivery format: Tape & Reel is continuous tape suitable for high-volume automated assembly; Cut Tape & Digi-Reel® is pre-cut tape on a reel for lower-volume or mixed-component applications. Component performance is identical.

Q: Why is MCR10ERTF30R0 listed as discontinued? A: MCR10ERTF30R0 is discontinued at DiGi Electronics. For new designs requiring ±1% tolerance with AEC-Q200 qualification, use ERJ-6ENF30R0V or RMCF0805FT30R0 instead.

Q: Can I use RC0805JR-0730RL in place of KTR10EZPJ300 in an automotive application? A: No. RC0805JR-0730RL lacks AEC-Q200 automotive qualification. Use only AEC-Q200 rated parts (KTR10EZPJ300, ERJ-6GEYJ300V, CRCW080530R0JNEA, or RMCF0805JT30R0) for automotive circuits.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean? A: MSL 1 indicates the component is not moisture sensitive and requires no special handling or baking procedures prior to soldering. All listed substitute parts maintain MSL 1 rating.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All parts listed meet ROHS3 compliance requirements.
