OX153K Equivalent & Substitute Parts

Part Overview

The OX153K is a 15 kOhms ±10% 1W through-hole resistor in axial package manufactured by Ohmite. This ceramic composition resistor features moisture resistance and pulse withstanding capabilities, designed for operating temperatures from -40°C to 220°C. The OX153K is classified as obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OX153K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

• Resistance value: 15 kOhms
• 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 to 220°C
• Temperature coefficient: -1000/-1600 ppm/°C
• Features: Moisture Resistant, Pulse Withstanding

The OX153KE meets all these parameters and is classified as a direct substitute for the obsolete OX153K.

Parameter Comparison

Engineering Selection Recommendations

The OX153KE is the direct equivalent substitute for the obsolete OX153K. Both parts are manufactured by Ohmite within the same OX series and share identical electrical specifications and physical dimensions. The OX153KE offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the OX153KE achieves ROHS3 compliance, whereas the OX153K is RoHS non-compliant. For new designs and production applications, the OX153KE is the appropriate selection. For legacy system maintenance requiring exact historical equivalence, the OX153K specifications remain valid until inventory depletion.

Frequently Asked Questions (FAQ)

Q: Can the OX153KE be used as a direct replacement for the OX153K in existing designs?

A: Yes. The OX153KE is electrically and mechanically identical to the OX153K. Both parts share the same resistance value (15 kOhms), tolerance (±10%), power rating (1W), package type (axial), physical dimensions (0.217" Dia x 0.650" L), operating temperature range (-40°C to 220°C), and ceramic composition with moisture resistance and pulse withstanding features.

Q: What is the primary difference between OX153K and OX153KE?

A: The OX153K is classified as obsolete, while the OX153KE maintains active product status. The OX153KE also achieves ROHS3 compliance, whereas the OX153K is RoHS non-compliant. Functionally and electrically, both parts are equivalent.

Q: Are there any package or form factor differences between these parts?

A: No. Both the OX153K and OX153KE are supplied in axial package configuration with identical physical dimensions of 0.217" Dia x 0.650" L (5.50mm x 16.50mm). The OX153KE is available in bulk packaging.

Q: What certifications and compliance standards apply to these resistors?

A: Both parts are classified as REACH Unaffected and carry ECCN EAR99 designation. The OX153KE achieves ROHS3 compliance. The OX153K does not meet RoHS requirements. Both parts have Not Applicable moisture sensitivity level (MSL) classification.

Q: Can these resistors be used in high-temperature applications?

A: Yes. Both the OX153K and OX153KE are rated for operating temperatures from -40°C to 220°C, supporting high-temperature circuit applications within this range.
