70F754AI-RC Equivalent & Substitute Parts

Part Overview

The 70F754AI-RC is a 750 µH unshielded drum core wirewound inductor manufactured by Bourns Inc., rated for 80 mA maximum current with a DC resistance of 22.9Ohm. This through-hole axial component operates across the temperature range of -55°C to 105°C and is compliant with ROHS3 and REACH standards. The product is currently obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution of the 70F754AI-RC is determined by the following critical parameters:

  • Inductance Value: 750 µH (exact match required)
  • Tolerance: ±5% (must match or be tighter)
  • Current Rating: Minimum 80 mA (equal or higher acceptable)
  • DC Resistance: Maximum 22.9Ohm (lower values acceptable)
  • Core Material: Iron (required for inductance stability)
  • Shielding: Unshielded (must match)
  • Operating Temperature Range: -55°C ~ 105°C (must cover or exceed)
  • Mounting Type: Through Hole Axial (physical compatibility requirement)
  • Compliance: ROHS3 and REACH standards (regulatory requirement)

The 2500R-22J from API Delevan Inc. meets all substitution criteria with improved electrical performance characteristics.

Engineering Selection Recommendations

The 2500R-22J is a direct functional substitute for the obsolete 70F754AI-RC. Both components maintain identical inductance values, tolerance specifications, and operating temperature ranges. The substitute part demonstrates superior electrical performance with higher current rating (95 mA versus 80 mA), lower DC resistance (14.4Ohm versus 22.9Ohm), and higher quality factor (60 versus 40 at 790kHz). Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The 2500R-22J is currently in active production status with confirmed inventory availability, providing supply chain continuity for applications previously using the 70F754AI-RC.

Frequently Asked Questions (FAQ)

Q: Can the 2500R-22J be used as a direct replacement for the 70F754AI-RC?

A: Yes. Both components share identical inductance (750 µH), tolerance (±5%), shielding (unshielded), core material (iron), operating temperature range (-55°C to 105°C), and axial through-hole mounting configuration. The substitute meets or exceeds all electrical requirements of the original part.

Q: What are the physical dimension differences between these parts?

A: The 70F754AI-RC measures 0.210" diameter × 0.250" length (5.33mm × 6.35mm). The 2500R-22J measures 0.240" diameter × 0.740" length (6.10mm × 18.80mm). Physical space constraints in the application must be verified before substitution.

Q: Does the lower DC resistance of the 2500R-22J affect circuit performance?

A: Lower DC resistance (14.4Ohm versus 22.9Ohm) reduces power dissipation and heat generation in the inductor. This represents an improvement for most applications and does not negatively impact circuit function when the inductance value and tolerance remain constant.

Q: Are there packaging differences between the original and substitute part?

A: The 70F754AI-RC is supplied in standard packaging. The 2500R-22J is supplied in Tape & Reel (TR) format. Both are through-hole axial components suitable for manual or automated assembly processes.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both the 70F754AI-RC and 2500R-22J are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
