Substitute Part Grouping Explanation

Substitution eligibility for the 825F15RE is determined by strict equivalence across the following critical parameters:

Resistance value: 15 Ohms (exact match required)
Tolerance: ±1% (exact match required)
Power dissipation: 25W (exact match required)
Composition: Wirewound (exact match required)
Temperature coefficient: ±20ppm/°C (exact match required)
Mounting configuration: Flanged chassis mount with solder lugs (exact match required)
Housing material: Aluminum (exact match required)
Package configuration: Axial, Box (exact match required)

The substitute parts listed below meet all these criteria and are therefore direct functional equivalents suitable for component replacement in applications originally specified for the 825F15RE.

Engineering Selection Recommendations

All three components—825F15RE, RH02515R00FE02, and UAL25-15RF8—are Active products with full RoHS compliance certification. The electrical specifications are identical across all parts, ensuring functional interchangeability in circuit applications.

The RH02515R00FE02 (Vishay Dale) provides ROHS3 compliance and operates across -55°C to 250°C, with moisture-resistant features and 2130 units in stock inventory.

The UAL25-15RF8 (Riedon) offers ROHS3 compliance with an extended operating temperature range of -55°C to 275°C and includes additional features such as current sense capability, flame proof construction, pulse withstanding, and safety certifications. This part has 1137 units in stock.

Physical dimensions vary slightly across all three parts, with maximum height differences of 0.022" (0.55mm). Component selection should account for available board space and thermal management requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can RH02515R00FE02 or UAL25-15RF8 be used as direct replacements for 825F15RE?

A: Yes. Both parts meet all critical electrical and mechanical specifications: 15 Ohms ±1%, 25W power rating, wirewound composition, ±20ppm/°C temperature coefficient, flanged chassis mount configuration with solder lugs, and aluminum housing. Physical dimensions are within acceptable tolerance for standard PCB layouts.

Q: What are the dimensional differences between these parts?

A: The 825F15RE measures 1.075" L × 1.102" W × 0.583" H. The RH02515R00FE02 measures 1.062" L × 1.080" W × 0.561" H. The UAL25-15RF8 measures 1.063" L × 1.079" W × 0.575" H. Maximum variation is approximately 0.022" in height and 0.023" in length. Verify clearance in confined mounting spaces before substitution.

Q: Are there compliance differences between these parts?

A: The 825F15RE carries RoHS Compliant certification. Both RH02515R00FE02 and UAL25-15RF8 carry ROHS3 Compliant certification, representing updated compliance standards. All parts are suitable for applications requiring RoHS compliance.

Q: What is the operating temperature range for each part?

A: The 825F15RE does not specify an operating temperature range in available documentation. The RH02515R00FE02 operates from -55°C to 250°C. The UAL25-15RF8 operates from -55°C to 275°C. For applications requiring operation beyond 250°C, the UAL25-15RF8 is the appropriate selection.

Q: Do these parts have different moisture sensitivity levels?

A: The 825F15RE and UAL25-15RF8 both carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The RH02515R00FE02 carries MSL Not Applicable, indicating no moisture sensitivity concern. All parts are suitable for standard storage and handling conditions.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For standard industrial applications, any of the three parts is suitable. For extended temperature operation beyond 250°C, select UAL25-15RF8. For applications requiring moisture-resistant features, RH02515R00FE02 is specified. Verify inventory availability and lead times for your procurement timeline.
