Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 40JR50 are identified based on matching the following critical parameters: resistance value (500 mOhms), tolerance (±5%), power rating (10W), composition (wirewound), package type (axial), temperature coefficient (±90ppm/°C), and physical dimensions (0.406" Dia x 1.902" L). The 40JR50E meets all these electrical and mechanical requirements and is therefore classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 40JR50E is a direct parametric equivalent to the 40JR50, with identical electrical specifications and physical dimensions. The primary distinction is RoHS compliance status: the 40JR50E is RoHS Compliant, while the 40JR50 is RoHS non-compliant. Selection between these parts should be based on regulatory requirements applicable to the end application. Both parts maintain Active product status and are suitable for equivalent circuit performance.

Frequently Asked Questions (FAQ)

Q: Can the 40JR50E be used as a direct replacement for the 40JR50?

A: Yes. The 40JR50E matches all critical electrical parameters (500 mOhms resistance, ±5% tolerance, 10W power rating, ±90ppm/°C temperature coefficient) and physical dimensions (0.406" Dia x 1.902" L axial package). Both are wirewound through-hole resistors with identical termination configuration.

Q: What is the difference between the 40JR50 and 40JR50E?

A: The primary difference is RoHS compliance. The 40JR50E is RoHS Compliant, while the 40JR50 is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The 40JR50 is supplied in standard packaging, while the 40JR50E is supplied in Bulk packaging. Both maintain the same axial component form factor and dimensions.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory and compliance requirements. For applications requiring RoHS compliance, the 40JR50E is the appropriate choice. Both parts are Active status and suitable for equivalent circuit performance.
