Ohmite 45F62R Equivalent & Substitute Parts

Part Overview

The Ohmite 45F62R is a 62 Ohm, 1% tolerance, 5W through-hole resistor with axial wirewound construction from the Ohmicone® 40 series. This component is classified as Active product status and is designed for applications requiring precision resistive elements with high power dissipation capability. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part number becomes unavailable or when alternative packaging configurations are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Ohmite 45F62R is determined by strict equivalence across the following critical parameters: resistance value (62 Ohms), tolerance (±1%), power rating (5W), composition (wirewound), package type (axial), temperature coefficient (±20ppm/°C), and physical dimensions (0.343" Dia x 0.937" L). Parts meeting all these specifications are classified as parametric equivalents and are electrically and mechanically interchangeable. The primary distinction between the main part and substitute parts is packaging configuration and RoHS compliance status, which do not affect functional performance in the circuit.

Parameter Comparison

Engineering Selection Recommendations

The Ohmite 45F62RE serves as a direct parametric equivalent to the 45F62R, with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory and compliance requirements. The 45F62R is RoHS non-compliant, while the 45F62RE achieves ROHS3 compliance. Applications subject to RoHS directives or customer specifications requiring RoHS3 compliance must utilize the 45F62RE. Both parts maintain Active product status and are suitable for continued design implementation. Packaging configuration differs between the two parts (standard versus bulk), which may influence procurement quantities and logistics considerations but does not affect circuit performance or mechanical fit.

Frequently Asked Questions (FAQ)

Q: Are the 45F62R and 45F62RE electrically interchangeable?

A: Yes. Both parts are identical in resistance value (62 Ohms), tolerance (±1%), power rating (5W), temperature coefficient (±20ppm/°C), and all other electrical parameters. They are direct electrical equivalents.

Q: Are the 45F62R and 45F62RE mechanically interchangeable?

A: Yes. Both parts share identical physical dimensions (0.343" Dia x 0.937" L), axial package type, and two-termination configuration. They are direct mechanical equivalents and require no PCB layout modifications.

Q: What is the primary difference between these parts?

A: The primary differences are RoHS compliance status and packaging configuration. The 45F62RE is ROHS3 compliant, while the 45F62R is RoHS non-compliant. The 45F62RE is supplied in bulk packaging, while the 45F62R uses standard packaging.

Q: Which part should I specify for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, specify the 45F62RE. For applications without RoHS compliance mandates, either part is acceptable based on availability and packaging requirements.

Q: Can I use the 45F62RE as a drop-in replacement for the 45F62R?

A: Yes, the 45F62RE is a direct drop-in replacement. No circuit modifications, PCB changes, or design alterations are required.

Q: Are there any temperature or environmental performance differences?

A: No. Both parts operate across identical temperature coefficients (±20ppm/°C) and environmental specifications. Performance is equivalent across all operating conditions.
