45F470E Equivalent & Substitute Parts

Part Overview

The Ohmite 45F470E is a 470 Ohm ±1% 5W through-hole resistor with axial wirewound construction, part of the Ohmicone® 40 series. This component is designed for applications requiring precision resistance with high power dissipation capability. The part maintains active product status with ROHS3 compliance and is suitable for general-purpose and industrial electronic circuits. Substitute parts are identified when original inventory is unavailable or when alternative sourcing is required while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 45F470E are qualified based on the following core electrical and mechanical parameters:

• Resistance value: 470 Ohms (exact match required)
• Tolerance: ±1% (equivalent precision class)
• Power rating: 5W (equivalent or higher dissipation capability)
• Composition: Wirewound (same construction type)
• Temperature coefficient: ±20ppm/°C (equivalent thermal stability)
• Package: Axial through-hole (same form factor and termination type)
• Compliance: ROHS3 compliant (regulatory equivalence)

The Riedon UB5C-470RF1 meets all core substitution criteria. While physical dimensions differ (6.40mm × 12.70mm versus 8.70mm × 23.80mm), both components maintain identical electrical specifications and axial package compatibility for standard through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite 45F470E and Riedon UB5C-470RF1 are active products with equivalent regulatory compliance (ROHS3 and REACH unaffected). Selection between these components should be based on:

• Availability and lead time requirements
• PCB layout constraints related to component dimensions
• Supplier inventory and pricing
• Application-specific environmental requirements (the Riedon UB5C-470RF1 includes additional features: current sense capability, flame proof construction, moisture resistance, and pulse withstanding characteristics)

Both components satisfy the core electrical and mechanical requirements for 470 Ohm ±1% 5W axial wirewound resistor applications.

Frequently Asked Questions (FAQ)

Q: Can the Riedon UB5C-470RF1 directly replace the Ohmite 45F470E in existing designs?

A: Yes. Both components share identical electrical specifications (470 Ohms ±1%, 5W, ±20ppm/°C) and axial through-hole package type. Physical dimensions differ, but both fit standard 0.1" pitch PCB layouts. Verify PCB clearance for the smaller Riedon component (6.40mm × 12.70mm).

Q: What are the key parameters that determine substitution eligibility?

A: Resistance value, tolerance, power rating, composition type, temperature coefficient, package form factor, and regulatory compliance status. All must match or exceed the original specification.

Q: Are there any compliance differences between these parts?

A: No. Both components are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements.

Q: Does the Riedon part's smaller size affect performance?

A: No. Smaller physical dimensions do not impact electrical performance. Both components deliver identical resistance, tolerance, power dissipation, and thermal characteristics.

Q: What additional features does the Riedon UB5C-470RF1 provide?

A: The Riedon component includes current sense capability, flame proof construction, moisture resistance, and pulse withstanding characteristics. These features do not affect basic substitution compatibility but may provide additional benefits in specific applications.
