OX683K Equivalent & Substitute Parts Reference

Part Overview

The OX683K is a 68 kOhms ±10% 1W axial through-hole resistor manufactured by Ohmite, featuring ceramic composition with moisture-resistant and pulse-withstanding characteristics. This part is classified as obsolete, making identification of active equivalent alternatives essential for ongoing design support and procurement continuity. The OX683KE serves as the direct parametric equivalent with identical electrical and mechanical specifications but maintains active product status.

Substitute Part Grouping Explanation

Substitution of the OX683K with the OX683KE is based on strict parametric equivalence across all electrical and mechanical specifications. Both parts share identical resistance values (68 kOhms), tolerance (±10%), power rating (1W), ceramic composition, temperature coefficient range (-1000 / -1600 ppm/°C), operating temperature limits (-40°C ~ 220°C), axial package configuration, and physical dimensions (0.217" Dia x 0.650" L). The substitution is valid because all critical parameters that determine functional compatibility remain unchanged between the main part and its equivalent.

Parameter Comparison

Engineering Selection Recommendations

The OX683KE is the direct substitute for the obsolete OX683K. Both parts are electrically and mechanically identical across all specified parameters. The primary distinction is product status: OX683K is obsolete while OX683KE maintains active availability. Additionally, OX683KE provides improved compliance posture with RoHS compliance certification, whereas OX683K is RoHS non-compliant. For new designs or ongoing procurement, OX683KE is the appropriate selection based on active product status and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can OX683KE directly replace OX683K in existing designs? A: Yes. The OX683KE is a parametric equivalent with identical electrical specifications (68 kOhms ±10%, 1W), ceramic composition, temperature coefficient, operating temperature range, and axial package dimensions. Direct substitution is valid for all circuit applications.

Q: What is the primary reason for substitution? A: The OX683K is classified as obsolete. The OX683KE provides the same functional performance with active product status and improved RoHS compliance.

Q: Are the physical dimensions identical? A: Yes. Both parts share identical dimensions of 0.217" Dia x 0.650" L (5.50mm x 16.50mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: What is the difference in RoHS compliance? A: OX683K is RoHS non-compliant, while OX683KE is RoHS Compliant. This distinction is relevant for applications subject to RoHS regulatory requirements.

Q: Are there any differences in electrical performance? A: No. Both parts maintain identical resistance values, tolerance, power rating, temperature coefficient, and operating temperature specifications.

Q: What packaging options are available? A: OX683K was supplied in standard packaging, while OX683KE is available in bulk packaging. Both maintain the same axial through-hole configuration.
