Ohmite 45J6K8 6.8kΩ 5W Axial Wirewound Resistor - Equivalent & Substitute Parts

Part Overview

The Ohmite 45J6K8 is a 6.8 kOhms ±5% 5W through-hole resistor with axial wirewound construction from the Ohmicone® 40 series. This component is classified as Active product status with 724 units currently in stock. Equivalent and substitute parts are identified when identical electrical specifications and mechanical compatibility are maintained across resistance value, tolerance, power rating, and package type. The 45J6K8E variant is available as a direct parametric equivalent with enhanced compliance characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 45J6K8 is determined by strict equivalence across the following critical parameters:

• Resistance value: 6.8 kOhms
• Tolerance: ±5%
• Power rating: 5W
• Composition: Wirewound
• Package configuration: Axial with 2 terminations
• Physical dimensions: 0.343" Dia x 0.937" L (8.70mm x 23.80mm)
• Temperature coefficient: ±20ppm/°C

The 45J6K8E meets all parametric requirements for direct substitution. Packaging differences (tape and reel versus bulk) do not affect electrical or mechanical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 45J6K8 and 45J6K8E are Active status components suitable for circuit applications requiring 6.8 kOhms 5W axial wirewound resistors. Selection between these parts should consider compliance requirements:

The 45J6K8E is RoHS Compliant with defined operating temperature range (-55°C ~ 275°C) and MSL rating of 1 (Unlimited), making it suitable for applications with environmental or regulatory compliance mandates. The 45J6K8 is RoHS non-compliant and lacks specified operating temperature data.

Both parts are electrically and mechanically identical in all critical parameters. Packaging format (bulk for 45J6K8E versus standard for 45J6K8) does not affect circuit performance or board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 45J6K8E directly replace the 45J6K8 in existing designs?

A: Yes. Both parts are parametrically equivalent with identical resistance (6.8 kOhms), tolerance (±5%), power rating (5W), composition (wirewound), package type (axial), and physical dimensions (0.343" Dia x 0.937" L). No circuit modifications are required.

Q: What is the difference between the 45J6K8 and 45J6K8E?

A: The primary differences are packaging format (bulk versus standard), RoHS compliance status (non-compliant versus compliant), and specified operating temperature range (-55°C ~ 275°C for the 45J6K8E). Electrical and mechanical specifications are identical.

Q: Does packaging format affect circuit compatibility?

A: No. Packaging format (bulk or tape and reel) affects only procurement and handling logistics. Once installed on a circuit board, both parts perform identically.

Q: Which part should be selected for new designs?

A: Selection depends on compliance requirements. For applications requiring RoHS compliance or defined operating temperature specifications, the 45J6K8E is the appropriate choice. Both parts are Active status and suitable for production use.

Q: Are there any thermal or environmental differences between these parts?

A: The 45J6K8E specifies an operating temperature range of -55°C ~ 275°C with MSL rating 1 (Unlimited). The 45J6K8 does not provide operating temperature specifications. Both share identical temperature coefficient (±20ppm/°C).
