Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 91J1K3E are identified based on strict parametric equivalence. The primary substitution criterion is electrical and mechanical compatibility, determined by the following key parameters:

• Resistance value: 1.3 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 1.5W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.142" Dia x 0.453" L (3.60mm x 11.50mm) (exact match required)
• Temperature coefficient: ±30ppm/°C (exact match required)
• Number of terminations: 2 (exact match required)

The Ohmite 91J1K3 meets all parametric requirements for direct substitution with the 91J1K3E.

Parameter Comparison

Engineering Selection Recommendations

Both the 91J1K3E and 91J1K3 are Active status components from Ohmite's Series 90 wirewound resistor line. The 91J1K3E is ROHS3 compliant, while the 91J1K3 is RoHS non-compliant. Selection between these parts depends on regulatory and compliance requirements for the end application. For applications requiring RoHS3 compliance, the 91J1K3E is the appropriate choice. For applications without RoHS compliance mandates, the 91J1K3 provides equivalent electrical and mechanical performance. Both parts share identical electrical specifications, physical dimensions, and thermal characteristics, ensuring functional interchangeability within their respective compliance frameworks.

Frequently Asked Questions (FAQ)

Q: Can the 91J1K3 be used as a direct replacement for the 91J1K3E?

A: The 91J1K3 is electrically and mechanically equivalent to the 91J1K3E. The primary difference is RoHS compliance status. Direct substitution is possible only if RoHS3 compliance is not a requirement for your application.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution eligibility is determined by exact matching of resistance value (1.3 kOhms), tolerance (±5%), power rating (1.5W), composition (wirewound), package type (axial), physical dimensions (0.142" Dia x 0.453" L), temperature coefficient (±30ppm/°C), and termination count (2).

Q: Are there any dimensional differences between the 91J1K3E and 91J1K3?

A: No. Both parts share identical physical dimensions of 0.142" Dia x 0.453" L (3.60mm x 11.50mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: What is the difference in inventory availability?

A: The 91J1K3E has 876 units in stock, while the 91J1K3 has 762 units in stock. Both are available as new original components.

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

A: The 91J1K3E is ROHS3 compliant and is the appropriate selection for applications requiring RoHS compliance certification.
