Substitute Part Grouping Explanation

Substitute parts for the Ohmite 45J820 are qualified based on the following critical parameters:

• Resistance Value: 820 Ohms (exact match required)
• Tolerance: ±5% (equivalent tolerance specification)
• Power Rating: 5W (exact match required)
• Composition: Wirewound (technology type)
• Package Configuration: Axial through-hole (mechanical compatibility)
• Termination Count: 2 (pin configuration)

The Ohmite 45J820E meets all substitution criteria as a parametric equivalent, maintaining identical electrical performance and mechanical form factor compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 45J820E directly replace the 45J820 in existing designs?

A: Yes. Both parts maintain identical resistance value (820 Ohms), tolerance (±5%), power rating (5W), composition (wirewound), and axial package configuration. Electrical and mechanical compatibility is complete.

Q: Are there differences in temperature performance between these parts?

A: The temperature coefficient specification (±20ppm/°C) is provided only for the main part 45J820. Equivalent performance is assumed for the 45J820E based on identical composition and electrical ratings.

Q: What is the significance of the packaging difference between standard and Bulk formats?

A: Packaging format affects order quantity and handling procedures but does not impact electrical performance or mechanical fit. Selection depends on procurement volume requirements and inventory management practices.

Q: Do both parts meet the same regulatory classifications?

A: Yes. Both the 45J820 and 45J820E share identical RoHS non-compliant status, EAR99 ECCN classification, and 8533.21.0080 HTSUS coding.

Q: Are there any restrictions on using these parts in specific applications?

A: Both parts are classified as RoHS non-compliant. Applications subject to RoHS compliance requirements must account for this status during design qualification.
