Key Parameters

Substitute Part Grouping Explanation

The Vishay Dale RH01010R00FE02 qualifies as a direct substitute for the Ohmite 810F10RE based on the following critical parameters:

• Identical resistance value: 10 Ohms
• Matching tolerance specification: ±1%
• Equivalent temperature coefficient: ±20ppm/°C
• Identical composition: Wirewound
• Matching housing material: Aluminum
• Identical mounting feature: Flanges
• Matching lead style: Solder Lugs
• Compatible package type: Axial, Box
• Equivalent compliance certifications: ROHS3 Compliant, REACH Unaffected

The substitute part features a higher power rating (12.5W versus 10W) and slightly reduced maximum operating temperature (250°C versus 275°C). Physical dimensions remain substantially equivalent with negligible variation in length and width. The substitute includes moisture-resistant coating as an additional feature.

Parameter Comparison

Engineering Selection Recommendations

The Vishay Dale RH01010R00FE02 is suitable as a substitute for the Ohmite 810F10RE in applications where the operating temperature requirement does not exceed 250°C. Both components maintain identical electrical specifications (resistance, tolerance, temperature coefficient) and equivalent mechanical mounting characteristics. The substitute part's higher power rating (12.5W) provides additional thermal margin in power dissipation scenarios. Both parts satisfy ROHS3 compliance and REACH unaffected requirements for regulated markets. Selection between the original and substitute should be based on application temperature limits, inventory availability, and packaging requirements (Tray versus Bulk).

Frequently Asked Questions (FAQ)

Q: Can the Vishay Dale RH01010R00FE02 replace the Ohmite 810F10RE in all applications?

A: The substitute is compatible for applications operating at or below 250°C. If your application requires operation above 250°C up to 275°C, the original Ohmite part is required.

Q: What is the significance of the higher power rating on the substitute part?

A: The 12.5W rating on the Vishay Dale part versus 10W on the Ohmite part indicates greater thermal dissipation capability. This allows the substitute to handle higher continuous power loads without exceeding temperature limits, providing design margin in power-constrained applications.

Q: Are the physical dimensions interchangeable?

A: Yes. Both parts feature identical length (0.750" / 19.05mm) and width specifications (0.812" / 20.63mm for Ohmite; 0.800" / 20.32mm for Vishay Dale). Height variation is negligible (0.400" versus 0.405"). Flanged mounting and solder lug termination are identical, ensuring mechanical compatibility in chassis-mounted installations.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the Ohmite 810F10RE and Vishay Dale RH01010R00FE02 are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for restricted substance use.

Q: What is the difference between Tray and Bulk packaging?

A: Tray packaging (Ohmite 810F10RE) provides organized component presentation for automated assembly processes. Bulk packaging (Vishay Dale RH01010R00FE02) offers cost efficiency for high-volume applications. Both packaging types contain the same electrical and mechanical component specifications.

Q: Are the temperature coefficients identical?

A: Yes. Both parts specify ±20ppm/°C temperature coefficient, ensuring equivalent resistance stability across temperature variations within their respective operating ranges.
