Ohmite 41J75R Equivalent & Substitute Parts

Part Overview

The Ohmite 41J75R is a 75 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.

Substitute Part Grouping Explanation

Substitute parts for the 41J75R are identified based on electrical and mechanical parameter equivalence. The primary substitution criterion is parametric compatibility: all substitute parts must match the main part in resistance value (75 Ohms), tolerance (±5%), power rating (1W), composition (wirewound), package type (axial), temperature coefficient (±20ppm/°C), and physical dimensions (0.126" Dia x 0.437" L).

The 41J75RE is classified as a parametric equivalent because it maintains identical electrical specifications and mechanical form factor. The distinction between these part numbers lies in packaging configuration and compliance status, not in functional performance or physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 41J75R and 41J75RE are electrically and mechanically equivalent and suitable for direct substitution in circuit applications requiring a 75 Ohm, 1W axial wirewound resistor.

The 41J75RE offers ROHS3 compliance, making it the preferred selection for applications subject to RoHS regulations or customer specifications requiring RoHS-compliant components. The 41J75R remains suitable for applications where RoHS compliance is not a requirement.

Both parts maintain identical electrical performance, physical form factor, and thermal characteristics. Selection between these part numbers should be based on regulatory compliance requirements and packaging configuration needs rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can the 41J75RE be used as a direct replacement for the 41J75R?

A: Yes. The 41J75RE is a parametric equivalent with identical resistance value, tolerance, power rating, composition, package type, temperature coefficient, and physical dimensions. Direct substitution is electrically and mechanically compatible.

Q: What is the primary difference between the 41J75R and 41J75RE?

A: The primary differences are packaging configuration (41J75R is tape and reel; 41J75RE is bulk) and RoHS compliance status (41J75R is RoHS non-compliant; 41J75RE is ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts share identical temperature coefficient (±20ppm/°C), power rating (1W), and physical dimensions. Thermal and electrical performance are equivalent.

Q: Which part should be selected for RoHS-regulated applications?

A: The 41J75RE is ROHS3 compliant and is the appropriate selection for applications subject to RoHS regulations or customer specifications requiring RoHS compliance.

Q: Do these parts have identical footprints and mounting characteristics?

A: Yes. Both parts are axial package type with identical physical dimensions (0.126" Dia x 0.437" L / 3.20mm x 11.10mm) and two terminations. PCB footprints and mounting procedures are identical.
