43F62R Equivalent & Substitute Parts

Part Overview

The 43F62R is a 62 Ohm ±1% 3W axial wirewound through-hole resistor manufactured by Ohmite, part of the Ohmicone® 40 series. This component is designed for applications requiring precision resistance with moderate power dissipation in compact form factors. The part is currently active in production with 877 pieces available in new original stock. Substitute parts are identified when packaging configurations differ or when compliance requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 43F62R is determined by strict equivalence across the following critical parameters:

• Resistance value: 62 Ohms
• Tolerance: ±1%
• Power rating: 3W
• Composition: Wirewound
• Temperature coefficient: ±20ppm/°C
• Package configuration: Axial
• Physical dimensions: 0.220" Dia x 0.594" L (5.60mm x 15.10mm)
• Number of terminations: 2

The 43F62RE is classified as a parametric equivalent based on identical electrical characteristics and mechanical form factor. The primary distinction is packaging configuration (Bulk versus standard packaging) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 43F62R and 43F62RE are electrically and mechanically identical 62 Ohm ±1% 3W axial wirewound resistors from the Ohmicone® 40 series. Selection between these parts should be based on the following criteria:

43F62R is suitable for applications where RoHS non-compliant components are acceptable and standard packaging is preferred.

43F62RE is the appropriate choice for applications requiring ROHS3 compliance. This part maintains all electrical and mechanical specifications while meeting current environmental and regulatory standards. The bulk packaging configuration may be advantageous for high-volume procurement scenarios.

Both parts share identical performance characteristics, dimensional specifications, and reliability parameters. The choice between them is determined by regulatory compliance requirements and packaging logistics rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Are the 43F62R and 43F62RE electrically interchangeable?

A: Yes. Both parts have identical resistance values (62 Ohms), tolerance (±1%), power rating (3W), temperature coefficient (±20ppm/°C), and composition (wirewound). They are direct electrical equivalents.

Q: What is the difference between these two parts?

A: The primary differences are packaging configuration (standard versus bulk) and RoHS compliance status. The 43F62RE is ROHS3 compliant, while the 43F62R is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Can I use the 43F62RE as a direct replacement for the 43F62R in my circuit?

A: Yes. The 43F62RE is a direct mechanical and electrical substitute. It will function identically in any application designed for the 43F62R, with the added benefit of ROHS3 compliance if required by your design or regulatory standards.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions of 0.220" Dia x 0.594" L (5.60mm x 15.10mm) and use the same axial package configuration with 2 terminations.

Q: Which part should I specify for new designs?

A: For new designs, the 43F62RE is recommended due to its ROHS3 compliance status, which aligns with current environmental regulations and industry standards. It provides the same performance as the 43F62R with enhanced compliance credentials.

Q: Are there any performance differences between bulk and standard packaging?

A: No. Packaging configuration affects logistics and handling but does not impact electrical performance, reliability, or mechanical fit. Both packaging types contain identical components.
