Key Parameters

Substitute Part Grouping Explanation

The Ohmite 45J10RE qualifies as a parametric equivalent to the 45J10R based on matching electrical and mechanical specifications. Both parts share identical resistance value (10 Ohms), tolerance (±5%), power rating (5W), composition (wirewound), package type (axial), temperature coefficient (±20ppm/°C), and physical dimensions (0.343" Dia x 0.937" L). The primary distinction lies in packaging configuration and compliance certifications. The 45J10RE is supplied in Bulk packaging and carries RoHS Compliant status with MSL 1 (Unlimited), whereas the 45J10R is non-compliant with RoHS requirements. Both maintain Active product status and identical ECCN and HTSUS classifications.

Parameter Comparison

Engineering Selection Recommendations

Selection between the 45J10R and 45J10RE depends on regulatory and compliance requirements. The 45J10RE is the appropriate choice for applications subject to RoHS compliance mandates, as it carries full RoHS Compliant certification. The 45J10R remains suitable for applications without RoHS restrictions. Both parts are electrically and mechanically interchangeable, with identical performance characteristics across all specified operating parameters. The 45J10RE offers higher inventory availability (992 units versus 901 units) and is supplied in Bulk packaging, which may provide cost advantages for high-volume procurement. Operating temperature range for the 45J10RE is specified as -55°C ~ 275°C, providing defined thermal boundaries for circuit design.

Frequently Asked Questions (FAQ)

Q: Are the 45J10R and 45J10RE electrically identical? A: Yes. Both parts share identical resistance (10 Ohms), tolerance (±5%), power rating (5W), temperature coefficient (±20ppm/°C), and composition (wirewound). They are electrically interchangeable.

Q: What is the primary difference between these parts? A: The 45J10RE carries RoHS Compliant certification, while the 45J10R is RoHS non-compliant. Packaging configuration also differs: 45J10RE is supplied in Bulk format.

Q: Can I substitute the 45J10R with the 45J10RE in my design? A: Yes, provided your application does not have specific packaging or compliance restrictions. Both parts are mechanically and electrically equivalent with identical axial form factors and dimensions.

Q: What does RoHS Compliant status mean for the 45J10RE? A: RoHS Compliant status indicates the 45J10RE meets Restriction of Hazardous Substances directives, making it suitable for applications and markets with RoHS regulatory requirements.

Q: Are the physical dimensions identical? A: Yes. Both parts measure 0.343" Dia x 0.937" L (8.70mm x 23.80mm) and use identical axial packaging, ensuring mechanical compatibility in PCB layouts.

Q: What is the operating temperature range? A: The 45J10RE specifies -55°C ~ 275°C. The 45J10R does not provide an explicit operating temperature range in available documentation.
