Hammond Manufacturing 1502 Equivalent & Substitute Parts

Part Overview

The Hammond Manufacturing 1502 is a 7 µH unshielded drum core wirewound inductor rated for 500 mA with 1.3 Ohm DC resistance, designed for through-hole axial mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. Substitute parts must maintain the specified inductance value and support the required current rating within acceptable DC resistance parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the Hammond Manufacturing 1502 is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 7 µH (exact match required)
• Current rating: minimum 500 mA (equal or higher acceptable)
• Mounting type: Through Hole
• Package: Axial

Secondary Compatibility Factors:

• DC resistance: 1.3 Ohm baseline (lower values acceptable; higher values require circuit validation)
• RoHS3 compliance: required for regulatory alignment
• Shielding configuration: unshielded preferred for form factor consistency

The Ohmite Z50E meets all primary criteria with superior current handling (1 A vs. 500 mA) and lower DC resistance (980 mOhm vs. 1.3 Ohm), making it a direct functional substitute.

Parameter Comparison

Engineering Selection Recommendations

The Ohmite Z50E is a qualified substitute for the Hammond Manufacturing 1502 based on the following factors:

Electrical Compatibility: Both components specify 7 µH inductance at the same test frequency (1 kHz). The Z50E provides doubled current capacity (1 A vs. 500 mA) and reduced DC resistance (980 mOhm vs. 1.3 Ohm), resulting in lower power dissipation and improved thermal performance in the application.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring continued compliance with environmental and safety standards.

Availability & Product Status: The Z50E is actively manufactured and stocked (930 Pcs available), whereas the Hammond 1502 is obsolete with limited remaining inventory (1,047 Pcs). Selection of the Z50E ensures long-term supply chain continuity.

Form Factor: Axial through-hole mounting is identical between both components, supporting direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Ohmite Z50E directly replace the Hammond 1502 in existing designs?

A: Yes. Both components share identical inductance (7 µH), axial through-hole mounting, and RoHS3 compliance. The Z50E's superior current rating (1 A vs. 500 mA) and lower DC resistance (980 mOhm vs. 1.3 Ohm) make it functionally equivalent and operationally superior for the same circuit application.

Q: What is the impact of the lower DC resistance in the Z50E?

A: Lower DC resistance reduces resistive power loss (I²R) in the inductor. For a 500 mA operating current, the Z50E dissipates approximately 245 mW compared to 325 mW in the Hammond 1502, improving thermal efficiency without affecting inductance performance.

Q: Are there physical dimension differences between these components?

A: The Ohmite Z50E specifies dimensions of 0.281" Dia x 1.000" L (7.14mm x 25.40mm). The Hammond 1502 dimensions are not provided in the available data. Physical verification is recommended before final PCB layout commitment.

Q: Does the tolerance specification differ between these parts?

A: The Hammond 1502 specifies ±10% inductance tolerance. The Ohmite Z50E tolerance is not provided in the available specifications. Tolerance matching should be verified against circuit design requirements.

Q: What is the inductance test frequency for each component?

A: The Ohmite Z50E specifies inductance measurement at 1 kHz. The Hammond 1502 test frequency is not provided in the available data.
