Substitute Part Grouping Explanation

Substitute parts for the 1210-393J are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

  • Inductance Value: 39 µH nominal with ±5% tolerance
  • Current Rating: 170 mA maximum
  • DC Resistance: 6.4 Ohm maximum
  • Core Material: Ferrite
  • Shielding Configuration: Unshielded
  • Package Form Factor: 1210 (3225 Metric) surface mount
  • Operating Temperature Range: -55°C to 125°C minimum
  • Frequency Characteristics: Q factor and self-resonant frequency within specified range

The 1210R-393J from Delevan meets all electrical and mechanical parameters identical to the main part. The primary distinction is packaging format and compliance certification status.

Engineering Selection Recommendations

1210-393J (API Delevan Inc.) is the primary part specification. This part is active in production and available in Tape & Reel packaging format. The part carries RoHS non-compliant status.

1210R-393J (Delevan) is a direct electrical and mechanical equivalent with identical inductance, current rating, DC resistance, core material, shielding, package dimensions, and thermal operating range. The 1210R-393J is ROHS3 compliant and available in Cut Tape and Digi-Reel® packaging formats. Selection between these parts depends on compliance requirements and packaging format availability for manufacturing processes.

Both parts are REACH Unaffected and classified under ECCN EAR99 and HTSUS 8504.50.8000.

Frequently Asked Questions (FAQ)

Q: Can the 1210R-393J replace the 1210-393J in production?

A: Yes. The 1210R-393J is electrically and mechanically identical to the 1210-393J. All critical parameters including inductance, current rating, DC resistance, core material, package dimensions, and operating temperature range are identical. The primary differences are packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and RoHS compliance status (ROHS3 Compliant versus non-compliant).

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: inductance value (39 µH ±5%), current rating (170 mA), DC resistance (6.4 Ohm maximum), core material (Ferrite), shielding configuration (Unshielded), package form factor (1210 / 3225 Metric), operating temperature range (-55°C to 125°C), and frequency characteristics (Q @ 2.5 MHz and self-resonant frequency).

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® are packaging and delivery formats only. They do not affect the electrical or mechanical characteristics of the inductor component itself.

Q: What is the significance of RoHS compliance difference?

A: RoHS compliance is a regulatory and supply chain consideration. The 1210-393J is RoHS non-compliant, while the 1210R-393J is ROHS3 compliant. Selection depends on end-product regulatory requirements and customer specifications.

Q: Are both parts suitable for the same circuit applications?

A: Yes. Both parts have identical electrical specifications and are suitable for the same RF filtering, power supply, and general-purpose inductor applications within the specified operating temperature range and current limits.
