PE-92102 100µH Toroidal Inductor Equivalent & Substitute Parts

Part Overview

The PE-92102 is a 100µH unshielded toroidal inductor rated for 2.6A continuous current with 100mOhm maximum DC resistance, designed for through-hole mounting applications. This part is classified as obsolete, making equivalent and substitute components necessary for ongoing production and maintenance applications. The PE-92102 remains available in inventory (702 pcs), but active alternatives with improved compliance status are recommended for new designs and long-term supply chain stability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PE-92102 is determined by the following critical parameters:

Direct Equivalent (Same Form Factor & Mounting):

• Inductance: 100 µH ±20%
• Current Rating: 2.6 A minimum
• DC Resistance: 100 mOhm maximum
• Mounting Type: Through Hole
• Package / Case: Radial, Vertical (Open)
• Operating Temperature: -40°C to 130°C minimum

Similar Functional Equivalent (Different Form Factor):

• Inductance: 100 µH ±20%
• Current Rating: 1.9 A minimum (reduced from 2.6 A)
• DC Resistance: 148 mOhm maximum (increased from 100 mOhm)
• Mounting Type: Surface Mount (different from through-hole)
• Operating Temperature: -20°C to 105°C (narrower range)

The PE-92102NL is a direct equivalent with identical electrical and mechanical specifications but improved RoHS3 compliance and active product status. The SLF12565T-101M1R6-PF is a functional alternative with the same inductance value but different mounting technology, core type, and reduced current rating, suitable only for applications where current requirements do not exceed 1.9A and surface-mount compatibility exists.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Recommended Primary Choice): PE-92102NL is the preferred substitute. It maintains identical electrical specifications (100µH, 2.6A, 100mOhm DCR), identical mechanical form factor (through-hole, radial vertical mounting, 21.59mm x 10.41mm), and identical operating temperature range (-40°C to 130°C). The PE-92102NL carries active product status and ROHS3 compliance, providing superior supply chain continuity and regulatory alignment compared to the obsolete PE-92102.

For Alternative Applications (Conditional Use): SLF12565T-101M1R6-PF is suitable only when all of the following conditions are met: (1) application circuit supports surface-mount technology, (2) maximum continuous current requirement does not exceed 1.9A, (3) operating temperature range does not fall below -20°C or exceed 105°C, and (4) increased DC resistance (148mOhm vs. 100mOhm) is acceptable for the application. This part offers shielded construction and ferrite core technology, which may provide EMI benefits in specific applications. However, its "Not For New Designs" status limits its suitability for long-term production.

Frequently Asked Questions (FAQ)

Q: Can PE-92102NL be used as a direct drop-in replacement for PE-92102? A: Yes. PE-92102NL is electrically and mechanically identical to PE-92102. Both parts have 100µH inductance, 2.6A current rating, 100mOhm maximum DCR, through-hole radial mounting, and -40°C to 130°C operating temperature. The only differences are packaging (tray vs. bulk) and compliance status (ROHS3 vs. non-compliant).

Q: What are the limitations of using SLF12565T-101M1R6-PF as a substitute? A: SLF12565T-101M1R6-PF has three significant limitations: (1) reduced current rating of 1.9A versus 2.6A, (2) increased DC resistance of 148mOhm versus 100mOhm, and (3) surface-mount packaging versus through-hole. Additionally, its operating temperature range (-20°C to 105°C) is narrower than the PE-92102 (-40°C to 130°C). This part is suitable only for applications that can accommodate these parameter changes.

Q: Why is PE-92102 classified as obsolete? A: PE-92102 is obsolete due to its RoHS non-compliant status and the availability of compliant alternatives. PE-92102NL provides an active, ROHS3-compliant equivalent with identical specifications, making the original PE-92102 unnecessary for new designs and future production.

Q: Are there packaging differences between PE-92102 and PE-92102NL? A: Yes. PE-92102 is supplied in bulk packaging, while PE-92102NL is supplied in tray packaging. Electrically and mechanically, both parts are identical. Tray packaging may provide handling and assembly advantages in automated production environments.

Q: Can SLF12565T-101M1R6-PF be used in high-temperature applications? A: No. SLF12565T-101M1R6-PF has a maximum operating temperature of 105°C, which is 25°C lower than PE-92102's 130°C maximum. Applications requiring operation above 105°C must use PE-92102 or PE-92102NL.

Q: What is the impact of increased DC resistance in SLF12565T-101M1R6-PF? A: The SLF12565T-101M1R6-PF has 48mOhm higher DC resistance (148mOhm vs. 100mOhm). This increases power dissipation and heat generation at the same current levels. For a 1.9A load, the SLF12565T-101M1R6-PF dissipates approximately 0.535W compared to 0.338W for PE-92102, a 58% increase. Applications with tight thermal budgets should account for this difference.
