KTR25JZPJ6R2 Equivalent & Substitute Parts

Part Overview

The KTR25JZPJ6R2 is a 6.2 Ohms ±5% thick film chip resistor manufactured by Rohm Semiconductor in the 1210 (3225 Metric) package format. This component is rated for 0.333W (1/3W) power dissipation and meets automotive AEC-Q200 qualification standards with high voltage capability. The part is currently in active production status with 766 units available in inventory. Equivalent and substitute parts are identified when design requirements allow for tolerance upgrades, power rating increases, or manufacturer alternatives while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KTR25JZPJ6R2 is determined by the following criteria:

Primary Substitution Parameters:

• Resistance value must equal 6.2 Ohms
• Package / Case must be 1210 (3225 Metric)
• Operating temperature range must span -55°C ~ 155°C minimum
• Automotive AEC-Q200 rating must be maintained
• RoHS3 compliance required

Allowable Variations:

• Tolerance may be tightened from ±5% to ±1% (upgrade path)
• Power rating may be increased from 0.333W to higher values (0.5W, 0.667W) without circuit impact
• Temperature coefficient may be improved (reduced from ±200ppm/°C)
• Manufacturer may differ provided all electrical and mechanical specifications align

Non-Substitutable Parameters:

• Resistance value deviation
• Package size or footprint change
• Loss of AEC-Q200 automotive qualification
• Operating temperature range reduction

Engineering Selection Recommendations

KTR25JZPF6R20 (Upgrade Option): This part is a direct upgrade from the KTR25JZPJ6R2, maintaining identical resistance, power rating, and package specifications while improving tolerance from ±5% to ±1%. The temperature coefficient is also improved to ±100ppm/°C. Both parts are manufactured by Rohm Semiconductor and carry AEC-Q200 automotive qualification. Selection of this part is appropriate when circuit design requires tighter tolerance control. Inventory availability is significantly higher at 4090 units.

ESR25JZPJ6R2 (Higher Power Rating): This Rohm Semiconductor part maintains the same resistance value, tolerance, and package as the main part but provides increased power dissipation capability at 0.667W (2/3W) versus 0.333W. This substitution is suitable for applications where thermal margin or power handling requirements exceed the original specification. AEC-Q200 qualification and RoHS3 compliance are maintained. The part features pulse withstanding capability.

AC1210FR-076R2L (Alternative Manufacturer): This YAGEO part provides equivalent 6.2 Ohm resistance in the 1210 package with ±1% tolerance and 0.5W power rating. It maintains AEC-Q200 automotive qualification and RoHS3 compliance. The packaging format differs slightly (Cut Tape & Digi-Reel versus Tape & Reel) and physical dimensions show minor variation (0.122" L x 0.102" W versus 0.126" L x 0.098" W). This option is suitable when YAGEO sourcing is preferred or when the intermediate power rating of 0.5W is required.

Frequently Asked Questions (FAQ)

Q: Can KTR25JZPF6R20 be used as a direct replacement for KTR25JZPJ6R2?

A: Yes. Both parts share identical resistance (6.2 Ohms), power rating (0.333W), package (1210), and operating temperature range (-55°C ~ 155°C). The KTR25JZPF6R20 offers improved tolerance (±1% versus ±5%) and lower temperature coefficient (±100ppm/°C versus ±200ppm/°C), making it a compatible upgrade with no circuit modifications required.

Q: What is the difference between the ESR25JZPJ6R2 and the main part?

A: The ESR25JZPJ6R2 differs in power rating (0.667W versus 0.333W) and features pulse withstanding capability. Resistance, tolerance, package, and temperature range are identical. This part is suitable when higher power dissipation is required in the circuit.

Q: Are all substitute parts automotive qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification, matching the main part specification.

Q: What are the packaging differences between these parts?

A: KTR25JZPJ6R2, KTR25JZPF6R20, and ESR25JZPJ6R2 are supplied in Tape & Reel (TR) format. AC1210FR-076R2L is supplied in Cut Tape (CT) & Digi-Reel format. All parts use the same 1210 (3225 Metric) package case with minor dimensional variations within tolerance.

Q: Can tolerance be downgraded from ±1% to ±5%?

A: Tolerance downgrade is not recommended in substitution scenarios. Tighter tolerance (±1%) is always compatible with circuits designed for looser tolerance (±5%), but the reverse is not true.

Q: Are all parts RoHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
