OY684K Equivalent & Substitute Parts

Part Overview

The OY684K is a 680 kOhms ±10% 2W axial through-hole resistor manufactured by Ohmite. This ceramic composition resistor features moisture resistance and pulse withstanding capabilities, designed for applications requiring reliable performance across the -40°C to 220°C operating temperature range. The OY684K is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution for the OY684K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

• Resistance value: 680 kOhms
• Tolerance: ±10%
• Power rating: 2W
• Composition: Ceramic
• Package configuration: Axial through-hole
• Physical dimensions: 0.276" Dia x 0.748" L (7.00mm x 19.00mm)
• Operating temperature range: -40°C ~ 220°C
• Temperature coefficient: -1000/-1600ppm/°C
• Features: Moisture Resistant, Pulse Withstanding
• Termination count: 2

The OY684KE meets all these parameters and is classified as an active product, providing a direct parametric equivalent for the obsolete OY684K.

Parameter Comparison

Engineering Selection Recommendations

The OY684KE is the direct parametric equivalent for the obsolete OY684K. Both parts are manufactured by Ohmite and share identical electrical specifications and physical dimensions. The primary distinction is product status: the OY684K is obsolete while the OY684KE is active and currently in production.

The OY684KE offers improved compliance status, meeting RoHS requirements compared to the non-compliant OY684K. This makes the OY684KE the appropriate selection for new designs and ongoing production requiring current component availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the OY684KE directly replace the OY684K in existing designs?

A: Yes. The OY684KE is a parametric equivalent with identical resistance, tolerance, power rating, physical dimensions, and operating temperature range. Direct substitution is supported without circuit modification.

Q: What is the primary reason to transition from OY684K to OY684KE?

A: The OY684K is obsolete. The OY684KE is the active equivalent from the same manufacturer, ensuring continued component availability for production and maintenance.

Q: Are there packaging differences between these parts?

A: Both parts use axial through-hole packaging with identical physical dimensions (0.276" Dia x 0.748" L). The OY684K is supplied in standard packaging while the OY684KE is supplied in bulk packaging.

Q: Does the OY684KE meet RoHS compliance requirements?

A: Yes. The OY684KE is RoHS Compliant, whereas the OY684K is RoHS non-compliant. This is a significant advantage for applications subject to RoHS regulations.

Q: Are the electrical characteristics identical between OY684K and OY684KE?

A: Yes. Both parts share identical resistance (680 kOhms), tolerance (±10%), power rating (2W), temperature coefficient (-1000/-1600ppm/°C), and operating temperature range (-40°C ~ 220°C).
