Ohmite 33J10R Equivalent & Substitute Parts

Part Overview

The Ohmite 33J10R is a 10 Ohm, 5% tolerance, 3W axial wirewound through-hole resistor from the High Energy Wirewound series. This component is classified as Active product status and is suitable for applications requiring precision power dissipation in compact form factors. Substitute parts are identified when equivalent electrical specifications and mechanical dimensions are maintained across alternative packaging configurations or compliance certifications.

Substitute Part Grouping Explanation

Substitute parts for the 33J10R are identified based on electrical parameter equivalence and mechanical compatibility. The substitution criteria are:

• Resistance value: 10 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 3W (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial (exact match required)
• Physical dimensions: 0.217" Dia x 0.594" L (exact match required)
• Number of terminations: 2 (exact match required)

The identified substitutes—33J10RE and 33J10RE-B—meet all electrical and mechanical parameters. Variations exist in packaging configuration (Bulk), RoHS compliance status, and moisture sensitivity level classification.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—33J10R, 33J10RE, and 33J10RE-B—are electrically and mechanically equivalent and maintain Active product status. Selection between these parts should be based on compliance requirements and supply chain considerations:

The 33J10RE offers ROHS3 compliance, making it suitable for applications subject to RoHS3 regulatory requirements. The 33J10R and 33J10RE-B do not carry explicit ROHS3 certification and should be evaluated against specific application compliance mandates.

The 33J10RE and 33J10RE-B are supplied in Bulk packaging, whereas the 33J10R packaging configuration is not specified. Packaging selection depends on procurement and assembly workflow requirements.

Moisture sensitivity level varies: 33J10R and 33J10RE are classified as Not Applicable, while 33J10RE-B is classified as MSL 1 (Unlimited). This distinction is relevant for storage and handling protocols in moisture-sensitive environments.

REACH compliance status is confirmed as REACH Unaffected for 33J10R and 33J10RE. The 33J10RE-B REACH status is listed as Vendor Undefined and should be clarified with the supplier for applications requiring explicit REACH compliance documentation.

Frequently Asked Questions (FAQ)

Q: Are the 33J10R, 33J10RE, and 33J10RE-B electrically interchangeable?

A: Yes. All three parts share identical electrical specifications: 10 Ohms resistance, ±5% tolerance, and 3W power rating. They are wirewound composition and maintain the same axial package configuration with identical physical dimensions (0.217" Dia x 0.594" L).

Q: What is the primary difference between these substitute parts?

A: The primary differences are RoHS compliance certification, moisture sensitivity level classification, and packaging configuration. The 33J10RE carries ROHS3 compliance, while the 33J10R is RoHS non-compliant and 33J10RE-B compliance status is not specified. Moisture sensitivity levels differ: 33J10R and 33J10RE are Not Applicable, while 33J10RE-B is MSL 1 (Unlimited).

Q: Can I use 33J10RE as a direct replacement for 33J10R in a circuit board assembly?

A: Yes, from an electrical and mechanical standpoint. However, verify that your application's compliance requirements align with the ROHS3 certification of the 33J10RE. Additionally, confirm that the Bulk packaging format is compatible with your procurement and assembly processes.

Q: Does moisture sensitivity level affect component performance?

A: Moisture sensitivity level classification determines storage, handling, and reflow requirements. The Not Applicable classification for 33J10R and 33J10RE indicates standard storage conditions are sufficient. The MSL 1 (Unlimited) classification for 33J10RE-B allows unlimited floor life without baking requirements.

Q: Which part should I select for a new design?

A: Selection depends on regulatory compliance mandates. For applications requiring RoHS3 compliance, specify 33J10RE. For applications without RoHS3 requirements, 33J10R or 33J10RE-B are suitable. Verify REACH compliance requirements with your supplier for 33J10RE-B before final selection.
