Substitute Part Grouping Explanation

Substitution eligibility for the 41J27R is determined by strict equivalence across the following critical parameters:

• Resistance value: 27 Ohms
• Tolerance: ±5%
• Power rating: 1W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±20ppm/°C
• Physical dimensions: 0.126" Dia x 0.437" L (3.20mm x 11.10mm)
• Termination count: 2

The identified substitute, 41J27RE, maintains identical electrical and mechanical specifications while differing only in packaging format (Bulk versus standard packaging) and RoHS compliance status. Both parts are manufactured by Ohmite within the same Ohmicone® 40 series and carry active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the 41J27R and 41J27RE are active production components manufactured by Ohmite with identical electrical performance and mechanical form factors. Selection between these parts is determined by compliance requirements and packaging specifications:

The 41J27R is suitable for applications where RoHS non-compliant components are acceptable and standard packaging is preferred. Current inventory of 917 units supports immediate availability.

The 41J27RE is the appropriate selection for designs requiring ROHS3 compliance. This substitute maintains full electrical and mechanical equivalence while meeting enhanced environmental and material restriction standards. Inventory of 749 units is available.

Both parts carry the same ECCN (EAR99) and HTSUS classification, ensuring consistent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Are the 41J27R and 41J27RE electrically identical?

A: Yes. Both components provide 27 Ohms ±5% at 1W with ±20ppm/°C temperature coefficient. Electrical performance is equivalent across all specified parameters.

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

A: The primary differences are packaging format (standard versus Bulk) and RoHS compliance status. The 41J27R is RoHS non-compliant, while the 41J27RE is ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Can I substitute 41J27RE for 41J27R in existing designs?

A: Yes, provided your design does not explicitly prohibit ROHS3 compliant components. The physical dimensions, pin configuration, and electrical characteristics are identical, ensuring direct form-fit-function compatibility.

Q: Does RoHS compliance affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical performance. Both parts deliver identical resistance, tolerance, and temperature coefficient specifications.

Q: Are both parts currently in production?

A: Yes. Both the 41J27R and 41J27RE maintain active product status with Ohmite and are available from inventory.
