Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Ohmite 41J1K2 are qualified based on the following critical parameters:

• Resistance Value: 1.2 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 1W (exact match required)
• Package Configuration: Axial through-hole (exact match required)
• Composition: Wirewound (exact match required)

The Ohmite 41J1K2E meets all substitution criteria as a parametric equivalent, maintaining identical electrical specifications and mechanical compatibility within the allowed parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite 41J1K2 and 41J1K2E are active products with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory Availability: The 41J1K2E offers 1083 units in stock compared to 836 units for the 41J1K2, providing greater supply continuity.
• Packaging Format: The 41J1K2 is supplied in standard packaging, while the 41J1K2E is supplied in bulk packaging. Bulk packaging may be advantageous for high-volume production environments.
• Compliance Status: Both parts share identical RoHS non-compliance and ECCN classifications, with no differentiation in regulatory posture.
• REACH Status: The 41J1K2E indicates REACH information available upon request, whereas the 41J1K2 is listed as REACH Unaffected. Clarification of REACH status should be obtained from the supplier for the 41J1K2E if regulatory compliance documentation is required.

Frequently Asked Questions (FAQ)

Q: Can the 41J1K2E be used as a direct replacement for the 41J1K2?

A: Yes. Both parts maintain identical resistance (1.2 kOhms), tolerance (±5%), power rating (1W), composition (wirewound), and axial package configuration. They are parametric equivalents suitable for direct substitution in circuit applications.

Q: What is the difference between the 41J1K2 and 41J1K2E?

A: The primary differences are packaging format (standard versus bulk) and inventory levels. The 41J1K2E does not specify a temperature coefficient value, whereas the 41J1K2 is rated at ±20ppm/°C. Both parts are manufactured by Ohmite and share identical electrical specifications and regulatory classifications.

Q: Are there any compliance considerations when substituting these parts?

A: Both parts are RoHS non-compliant and classified as EAR99 for export control purposes. They share the same HTSUS code (8533.21.0080). The 41J1K2E requires clarification of REACH status from the supplier, while the 41J1K2 is listed as REACH Unaffected.

Q: Does the axial package dimension remain consistent between these parts?

A: The 41J1K2 specifies dimensions of 0.126" Dia x 0.437" L (3.20mm x 11.10mm). The 41J1K2E does not provide dimensional specifications in the available data. Confirmation of mechanical compatibility should be obtained from the manufacturer if precise dimensional matching is required for board layout or mechanical assembly constraints.

Q: Which part should be selected for new designs?

A: Selection should be based on supply chain requirements and packaging preferences. Both parts are active products with equivalent electrical performance. The 41J1K2E offers higher inventory availability in bulk format, while the 41J1K2 is available in standard packaging with documented temperature coefficient specifications.
