Substitute Part Grouping Explanation

Substitute parts for the Ohmite 41J2K7 are identified based on strict electrical and mechanical parameter equivalence. The primary substitution criterion is the Ohmite 41J2K7E, which maintains identical electrical specifications: 2.7 kOhms resistance, ±5% tolerance, 1W power rating, wirewound composition, and ±20ppm/°C temperature coefficient. Both parts share the same axial package configuration with identical physical dimensions (0.126" Dia x 0.437" L). The key differentiator between these parts is packaging format and RoHS compliance status. Substitution is valid when these core parameters remain unchanged and the application environment permits the specified compliance profile.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite 41J2K7 and 41J2K7E are electrically and mechanically equivalent for applications requiring 2.7 kOhms ±5% 1W axial wirewound resistors. Selection between these parts depends on compliance requirements and packaging specifications. The 41J2K7E offers ROHS3 compliance, making it suitable for applications subject to RoHS3 regulatory requirements. The 41J2K7 maintains RoHS non-compliant status and is appropriate for applications without RoHS compliance mandates. Both parts are active products with adequate inventory levels. Packaging format differs between standard and bulk configurations; selection should align with procurement and assembly workflow requirements.

Frequently Asked Questions (FAQ)

Q: Are the 41J2K7 and 41J2K7E electrically interchangeable? A: Yes. Both parts share identical electrical specifications: 2.7 kOhms resistance, ±5% tolerance, 1W power rating, wirewound composition, and ±20ppm/°C temperature coefficient. They are direct electrical equivalents.
