Key Parameters

Substitute Part Grouping Explanation

The 40J35RE is classified as a parametric equivalent to the 40J35R. Substitution is valid based on the following criteria:

• Identical resistance value: 35 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
• Same manufacturer series: Ohmicone® 40

The primary difference between these parts is packaging format (standard vs. bulk) and RoHS compliance status, which do not affect electrical or mechanical performance in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 40J35R and 40J35RE are suitable for direct substitution in applications requiring a 35 Ohm, 10W axial wirewound resistor. Selection between these parts should be based on the following factors:

• RoHS Compliance: The 40J35RE is ROHS3 compliant, making it the appropriate choice for applications subject to RoHS regulations. The 40J35R is RoHS non-compliant and should be used only in applications where RoHS compliance is not required.
• Packaging Requirements: The 40J35R is supplied in standard packaging, while the 40J35RE is supplied in bulk packaging. Packaging selection depends on procurement and assembly workflow requirements.
• Inventory Availability: Both parts maintain active production status with comparable stock levels (1057 and 1046 units respectively).

Frequently Asked Questions (FAQ)

Q: Can the 40J35RE replace the 40J35R in all applications?

A: Yes, the 40J35RE is electrically and mechanically identical to the 40J35R. The only differences are packaging format and RoHS compliance status. Substitution is valid for any circuit application where the 40J35R is specified, provided RoHS compliance requirements are met.

Q: What is the difference between standard and bulk packaging?

A: Standard packaging (40J35R) and bulk packaging (40J35RE) refer to the quantity and presentation format of components during shipment and storage. Both formats contain identical components with identical electrical and mechanical properties. Packaging selection is determined by procurement volume and assembly process requirements.

Q: Does RoHS compliance affect circuit performance?

A: No. RoHS compliance status indicates the material composition of the component and does not affect electrical performance, power rating, tolerance, or temperature coefficient. Selection between RoHS-compliant and non-compliant versions depends on regulatory requirements for the end application.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the 40J35R and 40J35RE have identical dimensions of 0.406" Dia x 1.902" L (10.30mm x 48.30mm) and are both axial package types. They are mechanically interchangeable in PCB layouts and through-hole applications.

Q: What certifications apply to these parts?

A: Both parts carry identical ECCN (EAR99) and HTSUS (8533.21.0080) classifications. The 40J35RE additionally carries ROHS3 compliance certification. Both parts are REACH Unaffected.
