OX182K Equivalent & Substitute Parts

Part Overview

The OX182K is a 1.8 kOhms ±10% 1W through-hole resistor with axial leads, manufactured by Ohmite in the OX series. This ceramic composition resistor features moisture resistance and pulse withstanding capabilities, designed for operating temperatures from -40°C to 220°C. The OX182K is currently listed as obsolete, making identification of suitable substitutes necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OX182K is determined by strict equivalence across the following critical parameters:

• Resistance value: 1.8 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 OX182KE meets all these parameters and serves as a direct equivalent. The primary distinction is product status and packaging configuration, with OX182KE currently in active production.

Parameter Comparison

Engineering Selection Recommendations

The OX182KE is the direct equivalent for the obsolete OX182K. Both components share identical electrical and mechanical specifications, including resistance value, tolerance, power rating, package dimensions, and operating temperature range.

The OX182KE offers two significant advantages for new designs and component replenishment:

1. Active product status ensures continued availability and manufacturing support from Ohmite.
2. ROHS3 compliance meets current regulatory requirements, whereas the OX182K is RoHS non-compliant.

For applications requiring RoHS non-compliant components or legacy system maintenance, the OX182K remains available in existing inventory (805 pcs). For new designs and forward-compatible applications, OX182KE is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can OX182KE be used as a direct replacement for OX182K in existing designs?

A: Yes. The OX182KE is electrically and mechanically identical to the OX182K. All electrical parameters, physical dimensions, and performance characteristics are equivalent. The components are pin-compatible and footprint-compatible for through-hole applications.

Q: What is the difference between OX182K and OX182KE?

A: The primary differences are product status and regulatory compliance. OX182K is obsolete and RoHS non-compliant, while OX182KE is in active production and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between OX182K and OX182KE?

A: Both components use axial packaging with identical physical dimensions (0.217" Dia x 0.650" L). OX182KE is supplied in bulk packaging, while OX182K packaging configuration is not specified. This does not affect component functionality or compatibility.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: resistance value (1.8 kOhms), tolerance (±10%), power rating (1W), composition (ceramic), package type (axial), physical dimensions, operating temperature range (-40°C to 220°C), and features (moisture resistant, pulse withstanding).

Q: Is OX182KE suitable for new product designs?

A: Yes. OX182KE is in active production status and ROHS3 compliant, making it appropriate for new designs and applications requiring current regulatory compliance.
