Substitute Part Grouping Explanation

Substitution for the OX100K is determined by strict equivalence across the following parameters:

• Resistance value: 10 Ohms
• Tolerance: ±10%
• Power rating: 1W
• Composition: Ceramic
• Package configuration: Axial through-hole
• 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 OX100KE meets all these criteria and is classified as a parametric equivalent. This substitute maintains identical electrical and mechanical specifications while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The OX100KE is the direct parametric equivalent for the obsolete OX100K. Both components share identical electrical and mechanical specifications, ensuring drop-in compatibility in circuit applications. The OX100KE offers significant advantages for new designs and ongoing procurement:

• Active product status ensures continued availability and manufacturing support
• RoHS compliance aligns with current environmental and regulatory standards
• MSL rating of 1 (Unlimited) provides superior moisture handling characteristics compared to the non-applicable rating of the original part
• Identical dimensional and electrical parameters guarantee functional interchangeability without circuit redesign

For applications currently using OX100K components, transition to OX100KE is supported by full parametric equivalence across all critical specifications.
