OY334K Equivalent & Substitute Parts

Part Overview

The OY334K is a 330 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 OY334K is classified as obsolete, making identification of suitable substitutes essential for ongoing component procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY334K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following specifications without deviation:

• Resistance value: 330 kOhms
• Tolerance: ±10%
• Power rating: 2W
• Composition: Ceramic
• Package configuration: Axial with 2 terminations
• Operating temperature range: -40°C to 220°C
• Temperature coefficient: -1000/-1600 ppm/°C
• Physical dimensions: 0.276" Dia × 0.748" L (7.00mm × 19.00mm)
• Features: Moisture Resistant, Pulse Withstanding

The OY334KE meets all these criteria and is classified as a direct equivalent substitute for the obsolete OY334K.

Parameter Comparison

Engineering Selection Recommendations

The OY334KE is the direct equivalent substitute for the obsolete OY334K. Both components are manufactured by Ohmite and share identical electrical specifications and physical dimensions. The primary distinction is product status and regulatory compliance: the OY334K is obsolete, while the OY334KE is active and ROHS3 compliant. For new designs or component replenishment, the OY334KE is the appropriate selection. The OY334KE maintains full compatibility with existing circuit designs specified for the OY334K, with the added benefit of current manufacturing availability and enhanced regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the OY334KE be used as a direct replacement for the OY334K in existing circuits?

A: Yes. The OY334KE is electrically and mechanically identical to the OY334K. All electrical parameters, physical dimensions, and performance characteristics are equivalent, ensuring direct compatibility in existing applications.

Q: What is the primary reason for substituting the OY334K?

A: The OY334K is classified as obsolete. The OY334KE provides continued access to this component specification through an active, currently manufactured equivalent.

Q: Are there any differences in packaging between the OY334K and OY334KE?

A: Both components use identical axial packaging with 2 terminations and matching physical dimensions of 0.276" Dia × 0.748" L (7.00mm × 19.00mm). The OY334KE is supplied in bulk packaging, while the OY334K was supplied with standard packaging.

Q: Does the OY334KE meet current regulatory requirements?

A: Yes. The OY334KE is ROHS3 compliant and REACH unaffected, meeting current regulatory standards. The obsolete OY334K was RoHS non-compliant.

Q: Are the temperature coefficients identical between these parts?

A: Yes. Both the OY334K and OY334KE have identical temperature coefficients of -1000/-1600 ppm/°C and operate across the same temperature range of -40°C to 220°C.
