OX151K Equivalent & Substitute Parts

Part Overview

The OX151K is a 150 Ohms ±10% 1W 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 OX151K is currently classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OX151K is determined by strict equivalence across the following critical parameters:

• Resistance value: 150 Ohms
• Tolerance: ±10%
• Power rating: 1W
• Composition: Ceramic
• Package configuration: Axial with 2 terminations
• Physical dimensions: 0.217" Dia x 0.650" L (5.50mm x 16.50mm)
• Operating temperature range: -40°C ~ 220°C
• Temperature coefficient: -1000 / -1600 ppm/°C
• Features: Moisture Resistant, Pulse Withstanding

The OX151KE meets all specified parameters and serves as a direct equivalent to the obsolete OX151K.

Parameter Comparison

Engineering Selection Recommendations

The OX151KE is the direct equivalent substitute for the obsolete OX151K. Both components are manufactured by Ohmite and share identical electrical and mechanical specifications across all critical parameters including resistance, tolerance, power rating, package dimensions, and operating temperature range.

The primary distinction between the two parts is product status and regulatory compliance. The OX151K is obsolete, while the OX151KE maintains active production status. Additionally, the OX151KE achieves ROHS3 compliance, whereas the OX151K is RoHS non-compliant. For new designs or production requiring regulatory compliance with modern environmental standards, the OX151KE is the appropriate selection.

Both components maintain identical REACH and ECCN classifications, ensuring consistent regulatory treatment in supply chain applications.

Frequently Asked Questions (FAQ)

Q: Can the OX151KE be used as a direct replacement for the OX151K in existing designs?

A: Yes. The OX151KE is electrically and mechanically identical to the OX151K. All critical parameters—resistance, tolerance, power rating, package dimensions, operating temperature range, and temperature coefficient—are equivalent. The components are pin-compatible and functionally interchangeable.

Q: What is the primary reason to transition from OX151K to OX151KE?

A: The OX151K is obsolete and no longer in production. The OX151KE is the active production equivalent from the same manufacturer, ensuring continued component availability. Additionally, the OX151KE meets ROHS3 compliance requirements, supporting modern regulatory standards.

Q: Are the physical dimensions identical between OX151K and OX151KE?

A: Yes. Both components share identical axial package dimensions of 0.217" Dia x 0.650" L (5.50mm x 16.50mm), ensuring mechanical compatibility in PCB layouts and through-hole applications.

Q: Do both parts operate across the same temperature range?

A: Yes. Both the OX151K and OX151KE operate across the identical temperature range of -40°C to 220°C with matching temperature coefficients of -1000 / -1600 ppm/°C.

Q: What packaging options are available for the OX151KE?

A: The OX151KE is supplied in bulk packaging, whereas the OX151K packaging specification was not detailed. For specific packaging requirements, consult the supplier's current product documentation.
