OY103KE Equivalent & Substitute Parts

Part Overview

The OY103KE is a 10 kOhms ±10% 2W through-hole resistor in axial configuration, manufactured by Ohmite. This ceramic composition resistor features moisture resistance and pulse withstanding capability, designed for applications requiring moderate power dissipation in the 2W range. The part maintains Active product status with 1094 units currently in stock. Substitute parts become necessary when design requirements shift toward different power ratings, extended temperature ranges, or alternative packaging formats while maintaining the core electrical specifications of 10 kOhms resistance and ±10% tolerance.

Key Parameters

Substitute Part Grouping Explanation

The OC2K103E-TR qualifies as a substitute for the OY103KE based on the following matching parameters:

• Resistance value: 10 kOhms (identical)
• Tolerance: ±10% (identical)
• Composition: Ceramic (identical)
• Package configuration: Axial (identical)
• Number of terminations: 2 (identical)
• RoHS compliance: ROHS3 Compliant (identical)
• REACH status: REACH Unaffected (identical)

The substitution is valid despite differences in power rating (1W vs. 2W) and operating temperature range, as these represent design trade-offs rather than incompatibilities. The OC2K103E-TR operates at a lower power rating but extends the upper temperature limit to 230°C and provides high voltage capability.

Parameter Comparison

Engineering Selection Recommendations

Both the OY103KE and OC2K103E-TR maintain Active product status and full ROHS3 compliance with REACH unaffected designation. Selection between these parts depends on application-specific power dissipation requirements and thermal operating conditions. The OY103KE supports 2W continuous power dissipation within the -40°C to 220°C range. The OC2K103E-TR operates at 1W maximum power but extends temperature capability to 230°C and incorporates high voltage features. Both parts are manufactured by Ohmite with identical resistance, tolerance, and axial package configuration, ensuring electrical compatibility at the circuit level. Dimensional differences (0.276" vs. 0.311" diameter) must be evaluated for physical fit within the PCB layout.

Frequently Asked Questions (FAQ)

Q: Can the OC2K103E-TR replace the OY103KE in all applications?

A: The OC2K103E-TR is electrically equivalent for resistance and tolerance specifications. However, the 1W power rating versus the OY103KE's 2W rating requires verification that circuit power dissipation does not exceed 1W. Dimensional differences (0.311" vs. 0.276" diameter) must be confirmed for PCB layout compatibility.

Q: What are the key differences between these two parts?

A: The primary differences are power rating (2W vs. 1W), operating temperature upper limit (220°C vs. 230°C), and physical diameter (7.00mm vs. 7.90mm). The OC2K103E-TR adds high voltage capability while the OY103KE emphasizes moisture resistance.

Q: Are both parts RoHS compliant?

A: Yes, both the OY103KE and OC2K103E-TR are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging (OY103KE) is suitable for manual assembly or small-quantity applications. Cut Tape packaging (OC2K103E-TR) is designed for automated pick-and-place assembly processes and provides better handling for high-volume production.

Q: Can I use the OC2K103E-TR if my circuit requires 2W dissipation?

A: No. The OC2K103E-TR is rated for 1W maximum. Using it in a 2W application would exceed its power rating and compromise reliability.
