Substitute Part Grouping Explanation

Substitute parts for the HS10 27R J are identified through parametric equivalence matching. The substitution criteria are based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Resistance value: 27 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 identified substitute part maintains identical electrical performance characteristics and mechanical mounting compatibility. Dimensional variations within the width specification (0.650" vs. 0.626") remain within acceptable tolerances for chassis mount applications while preserving the same height and lead configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite HS10 27R J and ARCOL HS10 27R J are active production components with full RoHS compliance. The Ohmite variant carries ROHS3 certification, while the ARCOL variant maintains RoHS compliance with MSL rating of 1 (Unlimited). Both parts share identical electrical specifications and core mechanical dimensions, ensuring functional equivalence in circuit applications.

The ARCOL variant includes pulse withstanding capability as an additional feature. Selection between these parts should be based on inventory availability, compliance requirements specific to the application, and mechanical space constraints where the width difference (0.335" vs. 0.650") may be a consideration factor.

Frequently Asked Questions (FAQ)

Q: Can the ARCOL HS10 27R J directly replace the Ohmite HS10 27R J?

A: Yes. Both parts share identical electrical specifications (27 Ohms ±5%, 10W, ±100ppm/°C) and core mechanical dimensions (length and height). The width difference (0.335" vs. 0.650") does not affect electrical performance and remains compatible with standard chassis mount applications.

Q: What is the significance of the width dimension difference?

A: The width variation reflects different physical footprints on the chassis. The Ohmite variant is narrower (0.335"), while the ARCOL variant is wider (0.650"). Both maintain the same mounting flange configuration and solder lug lead style. Verify available mounting space in your application before selection.

Q: Are both parts RoHS compliant?

A: Yes. The Ohmite HS10 27R J is ROHS3 compliant. The ARCOL HS10 27R J is RoHS compliant with MSL rating 1 (Unlimited). Both meet environmental compliance requirements for standard industrial applications.

Q: What does the pulse withstanding feature on the ARCOL variant indicate?

A: The ARCOL variant includes pulse withstanding capability, indicating enhanced performance under transient voltage conditions. This feature does not affect basic substitution compatibility but may provide additional margin in applications subject to voltage spikes or pulse loading.

Q: How do I determine which part to order?

A: Verify the following: (1) Mechanical space availability for the width dimension, (2) RoHS compliance requirement level for your application, (3) Current inventory status and lead time. Both parts are electrically and mechanically interchangeable for standard 27 Ohm 10W wirewound chassis mount applications.
