Ohmite 41J20R Equivalent & Substitute Parts

Part Overview

The Ohmite 41J20R is a 20 Ohm, 1W axial wirewound through-hole resistor from the Ohmicone® 40 series. This component is classified as Active and remains in production. 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

The Ohmite 41J20RE is a parametric equivalent to the 41J20R. Both parts share identical electrical specifications: 20 Ohms resistance, ±5% tolerance, 1W power rating, wirewound composition, and ±20ppm/°C temperature coefficient. Both are packaged in axial configuration with matching physical dimensions (0.126" Dia x 0.437" L). The primary distinction between these part numbers is packaging format: the 41J20R is supplied in standard packaging, while the 41J20RE is supplied in bulk packaging. This substitution is valid for applications where the electrical and mechanical characteristics are the controlling factors and packaging format does not impose constraints on assembly or inventory procedures.

Parameter Comparison

Engineering Selection Recommendations

Both the 41J20R and 41J20RE are Active products manufactured by Ohmite and classified under identical export control (EAR99) and tariff (HTSUS 8533.21.0080) categories. The 41J20RE carries ROHS3 compliance, while the 41J20R is RoHS non-compliant. Selection between these parts should be based on regulatory requirements applicable to the end application. For applications subject to RoHS directives, the 41J20RE is the appropriate selection. For applications without RoHS constraints, either part is electrically and mechanically interchangeable. Packaging format (standard versus bulk) should be evaluated against procurement and assembly workflow requirements.

Frequently Asked Questions (FAQ)

Q: Are the 41J20R and 41J20RE electrically identical? A: Yes. Both parts have identical resistance (20 Ohms), tolerance (±5%), power rating (1W), composition (wirewound), and temperature coefficient (±20ppm/°C).

Q: What is the difference between these part numbers? A: The primary differences are packaging format (standard versus bulk) and RoHS compliance status. The 41J20RE is ROHS3 compliant; the 41J20R is RoHS non-compliant.

Q: Can I substitute the 41J20RE for the 41J20R in my design? A: Yes, provided that RoHS compliance is not a requirement for your application. If RoHS compliance is mandated, the 41J20RE is the required selection.

Q: Are the physical dimensions identical? A: Yes. Both parts are packaged in axial configuration with dimensions of 0.126" Dia x 0.437" L (3.20mm x 11.10mm).

Q: Do these parts have the same number of terminations? A: Yes. Both parts have 2 terminations.

Q: Which part should I use for new designs? A: Selection should be based on regulatory compliance requirements. For RoHS-compliant applications, use 41J20RE. For applications without RoHS constraints, either part is suitable.
