HS10 330R J Equivalent & Substitute Parts

Part Overview

The HS10 330R J is a 330 Ohms ±5% 10W wirewound chassis mount resistor manufactured by Ohmite in the ARCOL HS series. This component is designed for applications requiring reliable power dissipation in a compact aluminum-housed form factor with flanged mounting. The part is currently active in production with 1048 units in stock. Alternative equivalent parts may be required due to supply chain considerations, inventory availability, or specific application requirements where substitute models meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HS10 330R J is determined by strict equivalence across the following critical parameters:

• Resistance value: 330 Ohms
• Tolerance: ±5%
• Power rating: 10W
• Composition: Wirewound
• Temperature coefficient: ±100ppm/°C
• Housing material: Aluminum
• Mounting configuration: Flanges with solder lugs
• Package classification: Axial, Box

The ARCOL HS10 330R J qualifies as a parametric equivalent substitute. Both the Ohmite HS10 330R J and ARCOL HS10 330R J share identical electrical specifications and core mechanical characteristics. Dimensional variations exist in width (0.335" vs 0.650"), but both maintain the same length, height, and mounting interface. This dimensional difference does not affect functional interchangeability in standard chassis mount applications where flange spacing accommodates the specified range.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite HS10 330R J and ARCOL HS10 330R J are active production components with full RoHS compliance. The Ohmite variant carries ROHS3 certification, while the ARCOL variant carries standard RoHS certification. Both are classified under ECCN EAR99 for export purposes. Selection between these equivalents should be based on supply availability, lead time requirements, and inventory status. The ARCOL variant includes pulse withstanding capability as an additional feature. Moisture sensitivity level differs between manufacturers (Not Applicable for Ohmite; Level 1 Unlimited for ARCOL), which may influence storage and handling protocols depending on application environment.

Frequently Asked Questions (FAQ)

Q: Can the ARCOL HS10 330R J directly replace the Ohmite HS10 330R J in existing designs?

A: Yes. Both parts share identical electrical specifications (330 Ohms ±5%, 10W, ±100ppm/°C) and core mechanical characteristics (aluminum housing, flanged mounting, solder lugs). The width dimension difference (0.335" vs 0.650") does not affect functional interchangeability in standard chassis mount applications.

Q: What is the significance of the pulse withstanding feature listed for the ARCOL variant?

A: Pulse withstanding is an additional capability provided by the ARCOL HS10 330R J. This feature is not listed for the Ohmite variant but does not preclude substitution, as it represents an enhanced specification rather than a reduced one.

Q: How do the RoHS compliance levels differ between these parts?

A: The Ohmite HS10 330R J carries ROHS3 certification, while the ARCOL HS10 330R J carries standard RoHS certification. Both meet RoHS requirements; ROHS3 represents a more recent compliance standard. Selection should align with your application's regulatory requirements.

Q: What does Moisture Sensitivity Level (MSL) mean for these components?

A: MSL indicates moisture absorption risk during storage and handling. The Ohmite variant lists MSL as Not Applicable, indicating minimal moisture sensitivity. The ARCOL variant lists MSL 1 (Unlimited), indicating it can be stored indefinitely under controlled conditions without special drying requirements prior to soldering.

Q: Are there any dimensional constraints I should consider when substituting?

A: The primary dimensional difference is width: Ohmite measures 0.335" (8.50mm) while ARCOL measures 0.650" (16.50mm). Length (0.626" / 15.90mm) and seated height (0.346" / 8.80mm) are identical. Verify that your PCB layout or chassis mounting accommodates the wider ARCOL variant before substitution.
