OX104K Equivalent & Substitute Parts

Part Overview

The OX104K is a 100 kOhms ±10% 1W 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 temperature range from -40°C to 220°C. The OX104K is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OX104K is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for direct substitution:

• Resistance value: 100 kOhms
• Tolerance: ±10%
• Power rating: 1W
• Composition: Ceramic
• Package type: Axial
• 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
• Number of terminations: 2

The OX104KE meets all these criteria and serves as a direct equivalent to the obsolete OX104K.

Parameter Comparison

Engineering Selection Recommendations

The OX104KE is the direct equivalent for the obsolete OX104K. Both parts are manufactured by Ohmite within the OX series and maintain identical electrical and mechanical specifications. The primary distinction is product status: the OX104K is obsolete while the OX104KE is active and available for procurement.

An additional consideration is regulatory compliance. The OX104KE achieves ROHS3 compliance, whereas the OX104K is RoHS non-compliant. For applications subject to RoHS requirements, the OX104KE provides compliance while maintaining full functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the OX104KE be used as a direct replacement for the OX104K?

A: Yes. The OX104KE is electrically and mechanically identical to the OX104K across all specified parameters, including resistance, tolerance, power rating, composition, package type, dimensions, operating temperature range, and temperature coefficient.

Q: What is the primary reason to transition from OX104K to OX104KE?

A: The OX104K is classified as obsolete. The OX104KE is the active equivalent part from Ohmite, ensuring continued availability and supply chain reliability.

Q: Are there any compliance differences between these parts?

A: Yes. The OX104KE is ROHS3 compliant, while the OX104K is RoHS non-compliant. For applications requiring RoHS compliance, the OX104KE is the appropriate selection.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.217" Dia x 0.650" L (5.50mm x 16.50mm) and use axial packaging, ensuring compatibility with existing PCB layouts and through-hole assembly processes.

Q: Do both parts operate across the same temperature range?

A: Yes. Both the OX104K and OX104KE operate from -40°C to 220°C with identical temperature coefficients of -1000 / -1600 ppm/°C.
