Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HS50 1R5 F are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

• Resistance value: 1.5 Ohms
• Tolerance: ±1%
• Composition: Wirewound
• Temperature Coefficient: ±100ppm/°C
• Housing Type: Aluminum
• Mounting Feature: Flanges
• Lead Style: Solder Lugs
• Package Type: Axial, Box

Two substitute parts meet these criteria. The HS25 1R5 F differs in power rating (25W versus 50W) and physical dimensions, making it suitable for applications with lower power dissipation requirements. The HS50 1R5 F from ARCOL is a direct equivalent with identical electrical specifications and power rating, differing only in physical width dimension and pulse withstanding capability.

Parameter Comparison

Engineering Selection Recommendations

Selection between the HS50 1R5 F variants depends on application power dissipation requirements and physical space constraints.

The Ohmite HS50 1R5 F maintains ROHS3 compliance and is the primary specification. The ARCOL HS50 1R5 F provides equivalent electrical performance with RoHS compliance and includes pulse withstanding capability, with a wider physical profile (1.102" versus 0.559"). This variant is suitable for applications requiring enhanced transient protection.

The ARCOL HS25 1R5 F is a lower power alternative rated at 25W with reduced physical dimensions (1.075" length). This part is appropriate only for circuits where maximum power dissipation does not exceed 25W. All three parts maintain identical resistance, tolerance, temperature coefficient, and mounting characteristics.

Frequently Asked Questions (FAQ)

Can the HS25 1R5 F replace the HS50 1R5 F in all applications?

No. The HS25 1R5 F is rated for 25W maximum power dissipation, while the HS50 1R5 F is rated for 50W. Substitution is only valid in applications where actual power dissipation remains below 25W. Exceeding this rating will result in component failure.

What are the physical dimension differences between the substitute parts?

The Ohmite HS50 1R5 F measures 1.933" L x 0.559" W. The ARCOL HS25 1R5 F measures 1.075" L x 0.559" W. The ARCOL HS50 1R5 F measures 1.933" L x 1.102" W. All three maintain identical height of 0.583" when seated. Physical space availability may restrict substitution options.

Are all substitute parts RoHS compliant?

The Ohmite HS50 1R5 F is ROHS3 compliant. Both ARCOL variants are RoHS compliant. All three parts meet regulatory requirements for lead-free construction.

What is the difference between the two HS50 1R5 F variants?

Both the Ohmite and ARCOL HS50 1R5 F maintain identical electrical specifications and power rating. The ARCOL variant includes pulse withstanding capability and has a wider physical profile (1.102" versus 0.559" width). Selection depends on application requirements for transient protection and available mounting space.

Can these parts be used interchangeably in PCB designs?

Physical dimensions must be verified against PCB layout constraints. The HS25 1R5 F has a shorter length (1.075" versus 1.933"), and the ARCOL HS50 1R5 F has greater width (1.102" versus 0.559"). Mounting hole spacing and clearance requirements must be confirmed before substitution.
