OY102K Equivalent & Substitute Parts

Part Overview

The OY102K is a 1 kOhms ±10% 2W through-hole resistor with axial leads, manufactured by Ohmite. This ceramic composition resistor features moisture resistance and pulse withstanding capabilities, designed for applications requiring reliable performance across a wide operating temperature range of -40°C to 220°C. The OY102K is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY102K is determined by strict equivalence across the following critical parameters:

• Resistance value: 1 kOhms
• Tolerance: ±10%
• Power rating: 2W
• Composition: Ceramic
• Package configuration: Axial with 2 terminations
• Physical dimensions: 0.276" Dia x 0.748" L (7.00mm x 19.00mm)
• Operating temperature range: -40°C ~ 220°C
• Temperature coefficient: -1000 / -1600 ppm/°C
• Features: Moisture Resistant, Pulse Withstanding

The OY102KE meets all these parameters and is identified as a direct substitute for the obsolete OY102K.

Parameter Comparison

Engineering Selection Recommendations

The OY102KE is the direct equivalent for the obsolete OY102K. Both parts are manufactured by Ohmite within the OY series and maintain identical electrical and mechanical specifications. The primary distinction is product status and regulatory compliance: the OY102K is obsolete, while the OY102KE is active and ROHS3 compliant, making it the appropriate selection for new designs and ongoing procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can OY102KE be used as a direct replacement for OY102K? A: Yes. The OY102KE is electrically and mechanically identical to the OY102K across all specified parameters, including resistance, tolerance, power rating, package dimensions, and operating temperature range.

Q: What is the primary reason to transition from OY102K to OY102KE? A: The OY102K is classified as obsolete. The OY102KE is an active product from the same manufacturer and series, ensuring continued availability and supply chain reliability.

Q: Are there any compliance differences between these parts? A: Yes. The OY102K is RoHS non-compliant, while the OY102KE is ROHS3 compliant. Both maintain REACH Unaffected status and EAR99 ECCN classification.

Q: Will the OY102KE fit existing PCB layouts designed for OY102K? A: Yes. Both parts share identical axial package configuration and physical dimensions of 0.276" Dia x 0.748" L (7.00mm x 19.00mm), ensuring direct mechanical compatibility.

Q: Are the electrical characteristics identical between OY102K and OY102KE? A: Yes. Both parts maintain 1 kOhms resistance at ±10% tolerance, 2W power rating, -40°C to 220°C operating temperature range, and -1000 / -1600 ppm/°C temperature coefficient.
