OX101K Equivalent & Substitute Parts

Part Overview

The OX101K is a 100 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 OX101K is currently classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OX101K is determined by strict equivalence across the following critical parameters:

• Resistance Value: 100 Ohms (exact match required)
• Tolerance: ±10% (exact match required)
• Power Rating: 1W (exact match required)
• Composition: Ceramic (exact match required)
• Package Type: Axial (exact match required)
• Physical Dimensions: 0.217" Dia x 0.650" L / 5.50mm x 16.50mm (exact match required)
• Operating Temperature Range: -40°C ~ 220°C (exact match required)
• Temperature Coefficient: -1000 / -1600 ppm/°C (exact match required)
• Features: Moisture Resistant, Pulse Withstanding (exact match required)

The OX101KE meets all substitution criteria as a direct equivalent component manufactured by Ohmite with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The OX101KE is the direct substitute for the obsolete OX101K. Both components are manufactured by Ohmite and share identical electrical and mechanical specifications. The primary distinction is product status: the OX101K is obsolete while the OX101KE remains in active production with improved availability.

The OX101KE offers an additional compliance advantage: ROHS3 compliance, compared to the non-compliant status of the OX101K. Both components maintain REACH Unaffected status and share the same ECCN and HTSUS classifications. For new designs or ongoing procurement requirements, the OX101KE is the appropriate selection due to its active product status and enhanced regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the OX101KE be used as a direct replacement for the OX101K?

A: Yes. The OX101KE is electrically and mechanically identical to the OX101K. Both components have 100 Ohms resistance, ±10% tolerance, 1W power rating, ceramic composition, axial package type, identical physical dimensions, and matching operating temperature ranges and temperature coefficients.

Q: What is the primary reason to substitute the OX101K?

A: The OX101K is classified as obsolete. The OX101KE, manufactured by the same supplier, provides continuity for applications requiring this component specification while maintaining active production status and improved availability.

Q: Are there any compliance differences between the OX101K and OX101KE?

A: The OX101KE is ROHS3 compliant, while the OX101K is RoHS non-compliant. Both components are REACH Unaffected. For applications subject to RoHS requirements, the OX101KE is the appropriate selection.

Q: Do the OX101K and OX101KE have the same physical footprint?

A: Yes. Both components have identical dimensions of 0.217" Dia x 0.650" L (5.50mm x 16.50mm) and are packaged as axial through-hole resistors with two terminations. They are mechanically interchangeable in PCB layouts.

Q: What is the operating temperature range for these components?

A: Both the OX101K and OX101KE operate across -40°C to 220°C with a temperature coefficient of -1000 / -1600 ppm/°C.
