Substitute Part Grouping Explanation

Substitution for the HS50 4K7 J is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish valid substitutes:

Electrical Parameters (Must Match Exactly):

• Resistance value: 4.7 kOhms
• Tolerance: ±5%
• Power rating: 50W
• Composition: Wirewound
• Temperature coefficient: ±25ppm/°C

Mechanical Parameters (Must Match Exactly):

• Housing type: Aluminum
• Mounting feature: Flanges
• Lead style: Solder Lugs
• Package type: Axial, Box

Compliance Parameters:

• RoHS compliance status
• REACH compliance status

The HS50 4K7 J from Ohmite and the HS50 4K7 J from ARCOL share identical electrical specifications and core mechanical compatibility, establishing them as parametric equivalents within the 50W wirewound chassis mount resistor category.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite HS50 4K7 J and ARCOL HS50 4K7 J maintain Active product status with full RoHS compliance certification. Selection between these equivalents is based on availability and supply chain requirements. The ARCOL variant currently maintains higher inventory levels at 948 units compared to 716 units for the Ohmite version. Both components satisfy identical electrical load requirements and mechanical mounting specifications for 50W wirewound chassis mount applications. Component selection should prioritize current inventory status and lead time requirements for your production schedule.

Frequently Asked Questions (FAQ)

Q: Can the ARCOL HS50 4K7 J directly replace the Ohmite HS50 4K7 J?

A: Yes. Both components share identical electrical specifications (4.7 kOhms ±5% 50W wirewound), temperature coefficient (±25ppm/°C), and mechanical dimensions. Mounting interfaces, lead styles, and housing materials are equivalent.

Q: Are there dimensional differences between these parts?

A: The length and height-seated dimensions are identical at 1.933" L x 0.583" H (49.10mm x 14.80mm). The ARCOL variant has a width of 1.102" (28.00mm) compared to the Ohmite width of 0.559" (14.20mm). Verify mounting clearance in your application before substitution.

Q: What compliance certifications apply to both parts?

A: Both components are RoHS compliant and carry EAR99 ECCN classification. The Ohmite version is ROHS3 compliant; the ARCOL version is RoHS compliant. Both are REACH unaffected or vendor undefined, respectively.

Q: Which part should I select based on current availability?

A: The ARCOL HS50 4K7 J currently maintains 948 units in inventory compared to 716 units for the Ohmite version. Selection should align with your procurement timeline and supply chain strategy.

Q: Are these parts suitable for pulse withstanding applications?

A: The ARCOL variant explicitly lists pulse withstanding as a feature. Verify pulse specifications against your application requirements before final component selection.
