Parameter Comparison

Engineering Selection Recommendations

23J470E as Primary Substitute:

The 23J470E is a direct functional equivalent to the 23J470, with identical electrical and mechanical specifications. The primary distinction is regulatory compliance: the 23J470E is RoHS Compliant with MSL rating of 1 (Unlimited), whereas the original 23J470 is RoHS non-compliant. Both parts maintain Active product status and are manufactured by Ohmite within the same Series 20 product line.

Selection of the 23J470E is appropriate for applications requiring RoHS compliance or where moisture sensitivity classification is a design requirement. Both parts are suitable for direct substitution in through-hole circuit board applications requiring 470 Ohm, 3W wirewound resistors with flame retardant coating.

Frequently Asked Questions (FAQ)

Q: Can the 23J470E be used as a direct replacement for the 23J470?

A: Yes. The 23J470E is electrically and mechanically identical to the 23J470. Both parts have 470 Ohm resistance, ±5% tolerance, 3W power rating, wirewound composition, and identical physical dimensions. The primary difference is regulatory compliance status.

Q: What is the difference between the 23J470 and 23J470E?

A: The 23J470E is RoHS Compliant with MSL rating 1 (Unlimited), while the 23J470 is RoHS non-compliant with Not Applicable MSL. All electrical and mechanical parameters are identical.

Q: Are there any package or footprint differences between these parts?
