Ohmite 41J250 Equivalent & Substitute Parts

Part Overview

The Ohmite 41J250 is a 250 Ohm, 1W axial wirewound through-hole resistor from the Ohmicone® 40 series. This component is classified as Active and remains in production. Substitute parts are identified when original stock is unavailable, when packaging requirements differ, or when compliance certifications must be updated for specific applications.

Key Parameters

Substitute Part Grouping Explanation

The 41J250E qualifies as a parametric equivalent to the 41J250 based on identical electrical and mechanical specifications: 250 Ohm resistance, ±5% tolerance, 1W power rating, wirewound composition, axial package configuration, ±20ppm/°C temperature coefficient, and matching physical dimensions of 0.126" Dia x 0.437" L.

The primary distinction between these parts is packaging format and RoHS compliance status. The 41J250 is supplied in standard packaging with RoHS non-compliant status, while the 41J250E is supplied in bulk packaging and meets ROHS3 compliance requirements. Both parts share identical electrical performance and mechanical fit characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the 41J250 and 41J250E are Active products manufactured by Ohmite and are electrically and mechanically interchangeable for circuit applications requiring a 250 Ohm, 1W axial wirewound resistor.

Selection between these parts should be based on compliance requirements and packaging needs. The 41J250E is the appropriate choice for applications subject to ROHS3 compliance mandates or for procurement processes requiring RoHS-compliant components. The 41J250 remains suitable for applications without RoHS compliance requirements or for legacy system maintenance where original specifications must be preserved.

Packaging format differs between the two parts: standard packaging for 41J250 and bulk packaging for 41J250E. Bulk packaging may be preferred for high-volume production runs or inventory consolidation strategies.

Frequently Asked Questions (FAQ)

Q: Are the 41J250 and 41J250E electrically identical?

A: Yes. Both parts have identical resistance (250 Ohms), tolerance (±5%), power rating (1W), temperature coefficient (±20ppm/°C), and composition (wirewound). They perform identically in circuit applications.

Q: Can the 41J250E be used as a direct replacement for the 41J250?

A: Yes, from an electrical and mechanical standpoint. The 41J250E has identical physical dimensions (0.126" Dia x 0.437" L), axial package configuration, and two terminations. Substitution is valid unless the original specification explicitly requires RoHS non-compliant status.

Q: What is the difference in packaging between these parts?

A: The 41J250 uses standard packaging, while the 41J250E uses bulk packaging. This distinction affects order quantities, handling, and inventory management but does not impact electrical or mechanical performance.

Q: Which part should I specify for a new design?

A: Selection depends on compliance requirements. For designs subject to ROHS3 regulations or procurement policies requiring RoHS compliance, specify the 41J250E. For applications without such requirements, either part is acceptable based on availability and packaging preferences.

Q: Are both parts currently in production?

A: Yes. Both the 41J250 and 41J250E are classified as Active products and remain in current production by Ohmite.
