Ohmite 45J75R Equivalent & Substitute Parts

Part Overview

The Ohmite 45J75R is a 75 Ohm, 5% tolerance, 5W through-hole resistor with axial wirewound construction from the Ohmicone® 40 series. This component is classified as Active product status and is currently in stock with 975 pieces available. The 45J75R is designed for applications requiring precision wirewound resistor performance in standard axial packaging. Substitute parts are identified to provide alternative sourcing options while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The Ohmite 45J75RE is identified as a parametric equivalent to the 45J75R. Substitution is valid based on the following matching criteria:

• Resistance value: 75 Ohms
• Tolerance: ±5%
• Power rating: 5W
• Composition: Wirewound
• Package / Case: Axial
• Temperature Coefficient: ±20ppm/°C
• Physical dimensions: 0.343" Dia x 0.937" L (8.70mm x 23.80mm)
• Number of terminations: 2

The primary difference between these parts is packaging configuration and RoHS compliance status. The 45J75RE is supplied in Bulk packaging and is ROHS3 compliant, whereas the 45J75R is RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

Both the 45J75R and 45J75RE are Active status components suitable for direct substitution based on electrical and mechanical parameters. Selection between these parts should be determined by compliance requirements and packaging needs.

The 45J75RE is the appropriate choice for applications requiring ROHS3 compliance. The 45J75R remains suitable for applications where RoHS compliance is not mandated. Both parts are REACH Unaffected and carry identical ECCN (EAR99) and HTSUS (8533.21.0080) classifications.

Packaging configuration differs between the two parts: the 45J75R uses standard packaging while the 45J75RE is supplied in Bulk packaging. This distinction may affect procurement workflows and inventory management but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 45J75RE directly replace the 45J75R in existing designs?

A: Yes. The 45J75RE is electrically and mechanically identical to the 45J75R. All critical parameters including resistance value, tolerance, power rating, temperature coefficient, and physical dimensions are matched. Substitution is valid from a component performance perspective.

Q: What is the difference between the 45J75R and 45J75RE?

A: The primary differences are RoHS compliance status and packaging configuration. The 45J75RE is ROHS3 compliant while the 45J75R is RoHS non-compliant. The 45J75RE is supplied in Bulk packaging versus standard packaging for the 45J75R. Electrical and mechanical specifications are identical.

Q: Should I select the 45J75RE based on RoHS compliance?

A: RoHS compliance selection depends on your application requirements and regional regulations. If your design or market requires ROHS3 compliance, the 45J75RE is the appropriate choice. If RoHS compliance is not required, either part is suitable.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the 45J75R and 45J75RE have identical dimensions of 0.343" Dia x 0.937" L (8.70mm x 23.80mm). They are mechanically interchangeable in PCB layouts and mechanical assemblies.

Q: What does the packaging difference mean for procurement?

A: The 45J75R uses standard packaging while the 45J75RE is supplied in Bulk packaging. This affects how components are packaged and shipped but does not impact the component itself. Bulk packaging typically accommodates larger order quantities.
