Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELL-4GG101M is based on the following critical parameters:

Primary Matching Criteria:

• Inductance value: 100 µH (exact match required)
• Inductance tolerance: ±20% (matching tolerance band)
• Type: Wirewound (construction method)
• Shielding: Shielded (electromagnetic containment)
• Mounting type: Surface Mount (assembly compatibility)
• Test frequency: 100 kHz (measurement standard)

Secondary Compatibility Parameters:

• Current rating: Substitute must meet or exceed 250 mA continuous rating
• Saturation current (Isat): Substitute must meet or exceed 290 mA
• DC resistance (DCR): Lower DCR values are acceptable and provide improved performance
• Package classification: Nonstandard surface mount
• RoHS compliance: ROHS3 Compliant status maintained
• MSL rating: Level 1 (Unlimited) for storage and handling

The substitute part TYS4030101M-10 satisfies all primary matching criteria and exceeds secondary performance parameters, making it a valid electrical and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

The TYS4030101M-10 is a valid substitute for the obsolete ELL-4GG101M based on the following factors:

Electrical Equivalence: Both parts maintain identical inductance values (100 µH) and tolerance specifications (±20%) at the standard test frequency of 100 kHz. The substitute provides superior current handling capability (450 mA vs. 250 mA) and lower DC resistance (1.495 Ohm Max vs. 2.4 Ohm), resulting in reduced power dissipation and improved thermal performance in the application circuit.

Mechanical Compatibility: Both components are shielded wirewound inductors in nonstandard surface mount packages. The substitute exhibits slightly larger footprint dimensions (4.00mm x 4.00mm vs. 3.80mm x 3.80mm) and greater seated height (3.00mm vs. 1.40mm). PCB layout verification is required to confirm physical fit within the available mounting space.

Regulatory Compliance: Both parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental and handling requirements. The substitute is actively manufactured and available in production quantities, addressing the obsolescence status of the original part.

Product Availability: The ELL-4GG101M is classified as obsolete with limited remaining inventory. The TYS4030101M-10 is actively produced by Laird-Signal Integrity Products with substantial stock availability, ensuring long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the TYS4030101M-10 be used as a direct replacement for the ELL-4GG101M?

A: Electrical substitution is valid based on matching inductance (100 µH), tolerance (±20%), shielding, wirewound construction, and test frequency (100 kHz). Mechanical fit must be verified, as the substitute is larger (4.00mm x 4.00mm footprint, 3.00mm height vs. 3.80mm x 3.80mm footprint, 1.40mm height). PCB layout confirmation is required before implementation.

Q: What are the key performance differences between these parts?

A: The substitute provides superior electrical performance with 80% higher current rating (450 mA vs. 250 mA), 107% higher saturation current (600 mA vs. 290 mA), and 38% lower DC resistance (1.495 Ohm Max vs. 2.4 Ohm). These improvements reduce power loss and thermal stress in the circuit. The substitute also specifies self-resonant frequency (5.6 MHz) and operating temperature range (-40°C ~ 125°C), which are not provided for the original part.

Q: Are there any compliance or certification concerns with substitution?

A: Both parts maintain ROHS3 compliance and identical MSL Level 1 (Unlimited) ratings. No compliance barriers exist for substitution. The substitute is actively manufactured and certified, whereas the original part is obsolete.

Q: What physical constraints should be considered for PCB integration?

A: The substitute occupies a larger footprint (4.00mm x 4.00mm vs. 3.80mm x 3.80mm) and significantly greater height (3.00mm vs. 1.40mm). Verify available mounting space on the PCB and confirm clearance with adjacent components, particularly in high-density layouts or applications with height restrictions.

Q: Is the lower DC resistance of the substitute beneficial?

A: Lower DC resistance (1.495 Ohm Max vs. 2.4 Ohm) reduces resistive power dissipation (I²R losses) and improves thermal efficiency. This is advantageous in applications where thermal management or power efficiency is a design consideration. The substitute's superior current rating also provides additional design margin.

Q: What is the supply status difference between these parts?

A: The ELL-4GG101M is obsolete with limited remaining inventory (1189 Pcs). The TYS4030101M-10 is actively manufactured with substantial availability (49629 Pcs). For new designs or long-term production, the substitute ensures supply chain continuity and eliminates obsolescence risk.
