OY101K Equivalent & Substitute Parts

Part Overview

The OY101K is a 100 Ohms ±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 OY101K is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY101K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part OY101KE maintains identical specifications for resistance value, tolerance, power rating, composition type, and package configuration. Both components share the same axial lead format, physical dimensions (0.276" Dia x 0.748" L), operating temperature range, and functional features including moisture resistance and pulse withstanding capability. The substitution is valid based on complete parameter alignment within the allowed specifications for this product category.

Parameter Comparison

Engineering Selection Recommendations

The OY101KE serves as the direct substitute for the obsolete OY101K. Both components are manufactured by Ohmite and provide identical electrical and mechanical performance across all specified parameters. The primary distinction is product status: the OY101K is obsolete while the OY101KE remains in active production. Additionally, the OY101KE achieves ROHS3 compliance, whereas the OY101K is RoHS non-compliant. For new designs or ongoing procurement requirements, the OY101KE is the appropriate selection due to its active status and regulatory compliance posture.

Frequently Asked Questions (FAQ)
