Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY683K is determined by strict equivalence across the following critical parameters:

• Resistance value: 68 kOhms
• Tolerance: ±10%
• Power rating: 2W
• Composition: Ceramic
• Package configuration: Axial with 2 terminations
• Physical dimensions: 0.276" Dia × 0.748" L
• Operating temperature range: -40°C to 220°C
• Temperature coefficient: -1000/-1600 ppm/°C
• Features: Moisture Resistant, Pulse Withstanding

The OY683KE meets all these parameters and is classified as a direct equivalent. This substitute maintains identical electrical performance and mechanical compatibility while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The OY683KE is the direct equivalent for the obsolete OY683K. Both components are manufactured by Ohmite and share identical electrical and mechanical specifications. The primary distinction is product status and regulatory compliance: the OY683K is obsolete, while the OY683KE is active and ROHS3 compliant. For new designs and production continuity, the OY683KE is the appropriate selection. The OY683KE maintains full compatibility with existing PCB layouts and circuit designs specified for the OY683K.

Frequently Asked Questions (FAQ)

Q: Can the OY683KE be used as a direct replacement for the OY683K?

A: Yes. The OY683KE is electrically and mechanically identical to the OY683K. Both components have the same resistance value (68 kOhms), tolerance (±10%), power rating (2W), physical dimensions (0.276" Dia × 0.748" L), and operating temperature range (-40°C to 220°C). The OY683KE is the active equivalent and is recommended for all applications.

Q: What is the difference between OY683K and OY683KE?

A: The OY683K is obsolete, while the OY683KE is active. The OY683KE is ROHS3 compliant, whereas the OY683K is RoHS non-compliant. All other specifications are identical.

Q: Are there any packaging differences between these parts?

A: The OY683K and OY683KE share the same axial package configuration and physical dimensions. The primary packaging difference is that the OY683KE is supplied in bulk packaging, while the OY683K was supplied in standard packaging.

Q: Will the OY683KE work in existing PCB designs specified for the OY683K?

A: Yes. The OY683KE has identical lead spacing, diameter, and length, ensuring direct compatibility with existing PCB layouts and through-hole mounting specifications.

Q: What are the key parameters that define substitution for this resistor?

A: Substitution is determined by resistance value (68 kOhms), tolerance (±10%), power rating (2W), composition (ceramic), axial package type, physical dimensions (0.276" Dia × 0.748" L), operating temperature range (-40°C to 220°C), and temperature coefficient (-1000/-1600 ppm/°C).
