Substitute Part Grouping Explanation

Substitute parts for the HS50 150R F are classified based on the following substitution criteria:

Direct Manufacturer Equivalent (850F150E): Maintains identical electrical specifications—150 ohms ±1% at 50W power rating with wirewound composition and aluminum housing. This part differs in series designation (Metal-Mite®89 vs. HS) and packaging format (bulk vs. box), but provides equivalent electrical and mechanical performance for chassis mount applications with solder lug termination.

Parametric Equivalent (HS25 150R F): Shares the same resistance value (150 ohms ±1%), tolerance (±1%), composition (wirewound), housing material (aluminum), and mounting configuration (flanges with solder lugs). The primary difference is reduced power rating (25W vs. 50W), making this part suitable only for applications where the lower power dissipation requirement is acceptable.

Parameter Comparison

Engineering Selection Recommendations

850F150E Selection: This direct equivalent is suitable for applications requiring full 50W power dissipation with identical electrical performance. The improved temperature coefficient (±20ppm/°C vs. 100ppm/°C) provides enhanced stability across operating temperature ranges. ROHS3 compliance and higher inventory availability (1202 units) support production continuity. Bulk packaging format requires consideration for procurement workflows.

HS25 150R F Selection: This parametric equivalent is applicable only in circuits where maximum power dissipation does not exceed 25W. The identical resistance, tolerance, and mechanical mounting configuration ensure drop-in compatibility for lower-power applications. ROHS3 compliance and active production status confirm ongoing availability.

Frequently Asked Questions (FAQ)

Q: Can 850F150E directly replace HS50 150R F in all applications? A: Yes, for applications requiring 50W power dissipation. Both parts maintain 150 ohms ±1% resistance with wirewound composition, aluminum housing, and solder lug termination. The improved temperature coefficient of 850F150E (±20ppm/°C) provides superior stability.

Q: When is HS25 150R F a suitable substitute? A: HS25 150R F is suitable only when circuit power dissipation requirements do not exceed 25W. The reduced power rating is the limiting factor; all other electrical and mechanical parameters remain equivalent to the main part.

Q: What are the physical dimension differences between these parts? A: HS50 150R F measures 1.933" L × 1.102" W × 0.583" H (seated). 850F150E measures 1.938" L × 1.156" W × 0.620" H (seated). HS25 150R F measures 1.075" L × 0.559" W × 0.583" H (seated). Verify mounting clearances for space-constrained applications.

Q: Are all three parts RoHS compliant? A: Yes. HS50 150R F is RoHS Compliant. Both 850F150E and HS25 150R F are ROHS3 Compliant, representing current regulatory standards.

Q: What is the difference between box and bulk packaging? A: HS50 150R F is supplied in box packaging; 850F150E is supplied in bulk packaging. Packaging format affects procurement, storage, and handling procedures but does not impact electrical or mechanical performance.
