Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 810F50RE is determined by strict alignment of electrical and mechanical parameters. All substitute parts must maintain the following core specifications:

• Resistance value: 50 Ohms
• Tolerance: ±1%
• Composition: Wirewound
• Temperature Coefficient: ±20ppm/°C
• Housing: Aluminum with flanged mounting
• Lead configuration: Solder Lugs
• Compliance: ROHS3 Compliant

Power rating and operating temperature range are secondary parameters that may vary within acceptable limits for substitution. The identified substitute parts meet these criteria and are categorized as direct equivalents or performance upgrades based on their specifications.

Parameter Comparison

Engineering Selection Recommendations

The 810F50RE has three qualified substitute parts, each suitable for different application scenarios:

RH01050R00FE02 and TMC01050R00FE02 (Vishay Dale): Both parts provide a 25% power rating increase to 12.5W while maintaining identical electrical specifications. These upgrades are suitable for applications where thermal margin is required or where component stress reduction is a design objective. Operating temperature maximum is reduced to 250°C, which remains within typical industrial and commercial operating ranges. Both parts are ROHS3 compliant and available in higher inventory quantities.

UAL10-50RF8 (Riedon): This part matches the original 10W power rating and extends the operating temperature range to 275°C, identical to the 810F50RE. The UAL series includes additional features such as current sense capability, flame proof construction, pulse withstanding, and safety certifications. This part is suitable for applications requiring enhanced reliability features or extended temperature operation. ROHS3 compliance and MSL rating of 1 (Unlimited) provide flexibility for storage and handling.

All substitute parts maintain ROHS3 compliance and are active products with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RH01050R00FE02 or TMC01050R00FE02 be used as direct replacements for 810F50RE?

A: Yes. Both Vishay Dale parts are direct substitutes. They maintain identical resistance, tolerance, temperature coefficient, and mechanical mounting specifications. The 12.5W power rating provides additional thermal capacity. The operating temperature maximum of 250°C is lower than the 810F50RE but remains suitable for most applications operating below this threshold.

Q: What is the difference between RH01050R00FE02 and TMC01050R00FE02?

A: Both parts are manufactured by Vishay Dale with identical electrical and mechanical specifications. The difference lies in the series designation (RH versus TMC). Both provide 12.5W power rating and -55°C to 250°C operating range. Selection between these parts should be based on availability and internal design requirements of each series.

Q: Is UAL10-50RF8 a direct equivalent to 810F50RE?

A: Yes. The Riedon UAL10-50RF8 is a direct equivalent with matching 10W power rating and -55°C to 275°C operating temperature range. The UAL series includes additional features such as flame proof construction and pulse withstanding capability, making it suitable for applications requiring enhanced safety certifications.

Q: Can I use a 12.5W part in place of a 10W part?

A: Yes. A higher power rating provides additional thermal margin and does not degrade performance in applications designed for 10W components. The physical dimensions remain compatible with flanged mounting configurations.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (RH01050R00FE02, TMC01050R00FE02, and UAL10-50RF8) are ROHS3 compliant, matching the compliance status of the 810F50RE.

Q: What is the maximum operating temperature difference between substitute parts?

A: The 810F50RE and UAL10-50RF8 operate to 275°C, while RH01050R00FE02 and TMC01050R00FE02 operate to 250°C. For applications operating above 250°C, the 810F50RE or UAL10-50RF8 must be selected.

Q: Are there packaging differences between these parts?

A: The 810F50RE is supplied in Tray packaging, while all substitute parts are supplied in Bulk packaging. Mechanical form factor and mounting interface remain identical across all parts.
