Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1025-16K is determined by strict equivalence across the following critical parameters: inductance value (680 nH), tolerance (±10%), current rating (500 mA), DC resistance (600 mOhm maximum), operating temperature range (-55°C to 125°C), mounting type (through hole), package configuration (axial), core material (phenolic), and shielding classification (unshielded). The substitute part 1025R-16K meets all electrical and mechanical specifications identical to the main part. Differences in RoHS compliance status do not affect electrical or mechanical substitutability but may impact procurement decisions based on regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The 1025R-16K is a direct electrical and mechanical equivalent to the 1025-16K. Both parts are manufactured by API Delevan Inc. and share identical inductance, current rating, DC resistance, frequency characteristics, temperature range, and physical dimensions. The primary distinction is RoHS compliance status: the 1025-16K is RoHS non-compliant, while the 1025R-16K is ROHS3 compliant. Selection between these parts should be based on regulatory requirements applicable to the end application. For applications requiring RoHS3 compliance, the 1025R-16K is the appropriate choice. For applications without RoHS compliance mandates, either part is electrically and mechanically interchangeable. Both parts carry active product status and are available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can the 1025R-16K replace the 1025-16K in existing designs?

A: Yes. The 1025R-16K is electrically and mechanically identical to the 1025-16K across all specified parameters including inductance, current rating, DC resistance, frequency response, operating temperature, and physical dimensions. Direct substitution is supported without circuit redesign.

Q: What is the difference between these two part numbers?
