Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 41J7R5 are determined by matching the following critical electrical and mechanical parameters: resistance value (7.5 Ohms), tolerance specification (±5%), power rating (1W), composition type (wirewound), package configuration (axial), temperature coefficient (±50ppm/°C), and physical dimensions (0.126" Dia x 0.437" L). The identified substitute maintains identical electrical performance and mechanical compatibility while differing in packaging format and compliance certification status.

Parameter Comparison

Engineering Selection Recommendations

The 41J7R5E serves as a direct parametric equivalent to the 41J7R5, offering identical electrical and mechanical specifications. The primary distinction lies in compliance certification: the 41J7R5E achieves ROHS3 compliance, whereas the 41J7R5 is RoHS non-compliant. Selection between these parts should be based on project compliance requirements. Both parts maintain active product status and are available in new original stock. The 41J7R5E is supplied in bulk packaging, while the 41J7R5 uses standard packaging. Both components carry REACH Unaffected status and EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can the 41J7R5E replace the 41J7R5 in existing designs?

A: Yes. The 41J7R5E is electrically and mechanically identical to the 41J7R5, matching all critical parameters including resistance, tolerance, power rating, composition, package type, temperature coefficient, and physical dimensions. Substitution is valid from a functional standpoint.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format (standard versus bulk) and RoHS compliance status (non-compliant versus ROHS3 compliant). All electrical and mechanical specifications are identical.

Q: Which part should I select for RoHS-compliant applications?

A: The 41J7R5E is ROHS3 compliant and is the appropriate selection for applications requiring RoHS compliance. The 41J7R5 is RoHS non-compliant.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.126" diameter by 0.437" length (3.20mm x 11.10mm) and use identical axial package configuration, ensuring mechanical compatibility in PCB layouts and circuit designs.

Q: What is the temperature coefficient specification for these resistors?

A: Both parts operate with a temperature coefficient of ±50ppm/°C, providing consistent performance across the operating temperature range.
