Key Parameters

Substitute Part Grouping Explanation

The 40J15RE qualifies as a parametric equivalent to the 40J15R based on the following criteria:

• Identical resistance value: 15 Ohms
• Identical tolerance: ±5%
• Identical power rating: 10W
• Identical composition: Wirewound
• Identical package type: Axial
• Identical temperature coefficient: ±20ppm/°C
• Identical physical dimensions: 0.406" Dia x 1.902" L (10.30mm x 48.30mm)
• Identical number of terminations: 2

Both parts are manufactured by Ohmite and maintain full electrical and mechanical compatibility. The primary difference is packaging format (tape/reel versus bulk) and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 40J15R and 40J15RE are electrically and mechanically interchangeable for applications requiring a 15 Ohm, 10W axial wirewound resistor. Selection between these parts should be based on:

Compliance Requirements: The 40J15RE is RoHS Compliant, while the 40J15R is RoHS non-compliant. Applications subject to RoHS directives must use the 40J15RE.

Operating Temperature Specification: The 40J15RE provides a defined operating temperature range of -55°C to 275°C. The 40J15R does not specify an operating temperature range. Applications with defined thermal requirements should reference the 40J15RE datasheet.

Packaging Format: The 40J15R is supplied in tape/reel format, suitable for automated assembly. The 40J15RE is supplied in bulk format, suitable for manual assembly or small-volume applications.

Inventory Availability: Both parts maintain active production status with comparable stock levels (778 units for 40J15R, 708 units for 40J15RE).

Frequently Asked Questions (FAQ)

Q: Can the 40J15RE be used as a direct replacement for the 40J15R?

A: Yes. Both parts share identical electrical specifications (15 Ohms, ±5%, 10W) and mechanical dimensions (0.406" Dia x 1.902" L). They are functionally interchangeable in circuit applications.

Q: What is the difference between the 40J15R and 40J15RE?

A: The primary differences are packaging format (tape/reel versus bulk) and compliance certifications. The 40J15RE is RoHS Compliant and specifies an operating temperature range of -55°C to 275°C, while the 40J15R does not provide these specifications.

Q: Which part should I select for RoHS-compliant applications?

A: The 40J15RE is RoHS Compliant and must be used for applications subject to RoHS directives. The 40J15R is RoHS non-compliant.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both parts have identical dimensions of 0.406" Dia x 1.902" L (10.30mm x 48.30mm) and are compatible with the same PCB layouts and mechanical assemblies.

Q: What packaging format is each part supplied in?

A: The 40J15R is supplied in tape/reel format for automated pick-and-place assembly. The 40J15RE is supplied in bulk format for manual assembly or small-volume production runs.
