OX680K Equivalent & Substitute Parts

Part Overview

The OX680K is a 68 Ohms ±10% 1W through-hole axial resistor manufactured by Ohmite with ceramic composition, designed for moisture-resistant and pulse-withstanding applications. The part is currently obsolete, making identification of suitable substitutes essential for ongoing maintenance, repair, and legacy system support. The OX680KE serves as the direct equivalent, offering identical electrical and mechanical specifications with improved compliance status.

Substitute Part Grouping Explanation

Substitution of the OX680K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute must maintain:

• Identical resistance value: 68 Ohms
• Matching tolerance: ±10%
• Equal power rating: 1W
• Same composition: Ceramic
• Identical package configuration: Axial
• Matching operating temperature range: -40°C to 220°C
• Equivalent temperature coefficient: -1000/-1600 ppm/°C
• Identical physical dimensions: 0.217" Dia × 0.650" L
• Matching functional features: Moisture Resistant, Pulse Withstanding

The OX680KE meets all these criteria as a direct manufacturer equivalent from Ohmite's OX series.

Parameter Comparison

Engineering Selection Recommendations

The OX680KE is the direct equivalent for OX680K replacement. Both parts are manufactured by Ohmite and share identical electrical specifications, ceramic composition, and physical dimensions. The primary distinction is product status: the OX680K is obsolete while the OX680KE remains in active production.

For new designs and ongoing procurement, the OX680KE is the appropriate selection. The OX680KE provides ROHS3 compliance, whereas the OX680K is RoHS non-compliant. Both parts carry identical ECCN (EAR99) and HTSUS (8533.21.0090) classifications.

Frequently Asked Questions (FAQ)

Q: Can OX680KE be used as a direct replacement for OX680K?

A: Yes. The OX680KE is electrically and mechanically identical to the OX680K. Both are 68 Ohms ±10% 1W ceramic axial resistors with matching operating temperature ranges, temperature coefficients, and physical dimensions. The OX680KE is the active production equivalent.

Q: What is the difference between OX680K and OX680KE?

A: The OX680K is obsolete; the OX680KE is active production. The OX680KE is ROHS3 compliant, while the OX680K is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.217" diameter × 0.650" length (5.50mm × 16.50mm) and use axial through-hole packaging with two terminations.

Q: What are the key parameters that determine substitution eligibility?

A: Resistance value (68 Ohms), tolerance (±10%), power rating (1W), composition (ceramic), package type (axial), operating temperature range (-40°C to 220°C), temperature coefficient (-1000/-1600 ppm/°C), and physical dimensions must all match exactly.

Q: Is the OX680KE available in stock?

A: Availability varies by supplier. The OX680KE is supplied in bulk packaging and is in active production status, making it more readily available than the obsolete OX680K.
