Equivalent & Substitute Parts for Ohmite 41JR75

Part Overview

The Ohmite 41JR75 is a 750 mOhms ±5% 1W through-hole resistor with axial wirewound construction, part of the Ohmicone® 40 series. This component is currently active in production and maintains 704 pieces in new original stock. The 41JR75 operates within a temperature coefficient range of ±90ppm/°C and is housed in a compact axial package measuring 0.126" diameter by 0.437" length (3.20mm x 11.10mm). Identifying equivalent substitute parts is necessary when the primary part number becomes unavailable, when packaging requirements differ, or when compliance certifications must be updated for specific applications.

Substitute Part Grouping Explanation

Substitute parts for the 41JR75 are identified based on strict electrical and mechanical parameter matching. The primary substitution criterion is parametric equivalence: all substitute parts must maintain identical resistance value (750 mOhms), tolerance (±5%), power rating (1W), composition (wirewound), package type (axial), temperature coefficient (±90ppm/°C), and physical dimensions (0.126" Dia x 0.437" L). The 41JR75E qualifies as a parametric equivalent because it matches all critical electrical specifications and mechanical form factors. Packaging configuration (bulk versus standard) does not affect electrical or mechanical compatibility and represents a supply chain variation rather than a functional difference.

Parameter Comparison

Engineering Selection Recommendations

The 41JR75E serves as a direct parametric equivalent to the 41JR75, with all electrical and mechanical specifications matching precisely. Both parts are active products manufactured by Ohmite within the Ohmicone® 40 series. The primary distinction between these parts is compliance certification: the 41JR75E carries ROHS3 compliance, while the 41JR75 is RoHS non-compliant. Selection between these parts depends on application requirements. Applications subject to RoHS3 regulatory requirements must use the 41JR75E. Applications without RoHS3 mandates may use either part based on availability and packaging preference. Both parts maintain identical REACH and ECCN classifications. The 41JR75E currently maintains higher inventory availability (997 pieces versus 704 pieces), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can the 41JR75E replace the 41JR75 in existing designs? A: Yes. The 41JR75E is a parametric equivalent with identical electrical specifications (750 mOhms ±5%, 1W), composition (wirewound), temperature coefficient (±90ppm/°C), and physical dimensions (0.126" Dia x 0.437" L). Direct substitution is electrically and mechanically compatible.

Q: What is the difference between the 41JR75 and 41JR75E? A: The parts are electrically and mechanically identical. The 41JR75E is ROHS3 compliant, while the 41JR75 is RoHS non-compliant. Packaging configuration differs (bulk versus standard), but this does not affect component function or circuit performance.

Q: Does packaging type affect compatibility? A: No. Packaging configuration (bulk versus standard) is a supply chain variable and does not alter electrical performance or mechanical fit. Both packaging types contain identical components suitable for the same applications.

Q: Which part should be selected for RoHS3-regulated applications? A: The 41JR75E must be used for applications subject to RoHS3 requirements, as it carries ROHS3 compliance certification. The 41JR75 is not RoHS compliant and is unsuitable for regulated environments.

Q: Are there any performance differences between these parts? A: No. Both parts maintain identical resistance value, tolerance, power rating, temperature coefficient, and physical dimensions. Performance in circuit operation is equivalent.
