Substitute Part Grouping Explanation

Substitution eligibility for the TYS3010100M-10 is determined by strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Inductance value: 10 µH (exact match required)
• Inductance tolerance: ±20% (matching tolerance band)
• Shielding: Shielded configuration (electromagnetic containment requirement)
• Mounting type: Surface Mount (PCB assembly compatibility)
• Package footprint: 3.00 mm × 3.00 mm (physical placement constraint)
• Height - Seated: 1.00 mm maximum (board clearance requirement)
• RoHS3 Compliance: Required for regulatory alignment
• Moisture Sensitivity Level: 1 (Unlimited) for storage and handling compatibility

Secondary Compatibility Parameters:

• Current rating: Minimum 580 mA (or higher for design margin)
• DC resistance: Maximum 400 mOhm (or lower for reduced losses)
• Operating temperature range: Must encompass -40°C to 125°C or be compatible with application requirements
• Self-resonant frequency: 34 MHz or higher (frequency response consideration)

The substitute part NRH3010T100MN meets all primary criteria and demonstrates acceptable performance within secondary parameters, with the exception of product status classification.

Engineering Selection Recommendations

Primary Selection: TYS3010100M-10

The TYS3010100M-10 is the recommended choice for new designs and applications requiring long-term component availability. This part carries Active product status, indicating ongoing manufacturer support, continued production, and stable supply chain positioning. The component is available in standard Tape & Reel packaging suitable for automated assembly processes. The operating temperature range of -40°C to 125°C provides the widest thermal envelope, and the self-resonant frequency of 39 MHz supports higher frequency applications within the inductor's operational bandwidth.

Substitute Selection: NRH3010T100MN

The NRH3010T100MN from Taiyo Yuden is electrically compatible with the TYS3010100M-10 for applications where the primary part is unavailable. This substitute maintains the 10 µH inductance value, ±20% tolerance, shielded configuration, and identical physical footprint (3.00 mm × 3.00 mm × 1.00 mm). The higher current rating (620 mA versus 580 mA) and saturation current (600 mA versus 550 mA) provide additional design margin in current-limited applications.

Compatibility Considerations:

The NRH3010T100MN exhibits a 20 mOhm increase in maximum DC resistance (420 mOhm versus 400 mOhm), representing a 5% elevation in resistive losses. This parameter difference is acceptable for most power conversion and filtering applications where the primary design constraint is inductance value and current handling capacity rather than minimum loss performance.

The substitute part operates across -25°C to 120°C, which is narrower than the primary part's -40°C to 125°C range. Applications requiring operation at -40°C or above 120°C must retain the TYS3010100M-10.

The self-resonant frequency of the substitute (34 MHz) is 5 MHz lower than the primary part (39 MHz). This difference is not significant for standard filtering and energy storage applications operating at frequencies below 10 MHz.

Product Status Impact:

The NRH3010T100MN carries "Not For New Designs" status, indicating that Taiyo Yuden is not recommending this part for new product development. This classification reflects the manufacturer's strategic product portfolio decisions and does not necessarily indicate technical deficiency. However, for new designs with extended production lifecycles, the Active status of TYS3010100M-10 provides superior long-term supply assurance.

Frequently Asked Questions (FAQ)

Q1: Can NRH3010T100MN be used as a direct replacement for TYS3010100M-10 in existing designs?

A: Yes, the NRH3010T100MN is electrically and mechanically compatible with the TYS3010100M-10 for direct PCB substitution. Both parts share identical inductance (10 µH), tolerance (±20%), shielding, mounting type, and physical footprint (3.00 mm × 3.00 mm × 1.00 mm). The substitute's higher current rating and saturation current provide additional design margin. However, applications operating at -40°C or above 120°C must retain the primary part due to the narrower operating temperature range of the substitute.

Q2: What is the significance of the 20 mOhm difference in DC resistance between these parts?

A: The NRH3010T100MN exhibits a maximum DC resistance of 420 mOhm compared to 400 mOhm for the TYS3010100M-10, representing a 5% increase. In power conversion applications, this translates to proportionally higher resistive losses (I²R heating). For a 580 mA load, the additional loss is approximately 6.7 mW. This difference is negligible in most filtering and energy storage applications but may be significant in high-efficiency power supply designs where every milliwatt of loss impacts overall system efficiency.

Q3: Why does the substitute part have "Not For New Designs" status?

A: The "Not For New Designs" classification indicates that Taiyo Yuden is transitioning this product line and recommends alternative parts for new development. This status reflects manufacturer portfolio strategy rather than technical obsolescence. The part remains functionally sound and is suitable for sustaining production of existing designs or emergency supply situations. For new product development with multi-year production horizons, the Active status of TYS3010100M-10 ensures superior supply chain stability.

Q4: Are there packaging differences between these parts, and do they affect assembly?

A: Yes, the TYS3010100M-10 is supplied in Tape & Reel (TR) packaging, while the NRH3010T100MN is available in Cut Tape (CT) and Digi-Reel® formats. Tape & Reel packaging is optimized for high-volume automated assembly with pick-and-place equipment. Cut Tape and Digi-Reel formats are suitable for lower-volume production or manual assembly. If substituting the NRH3010T100MN in an automated assembly line configured for standard Tape & Reel components, packaging format conversion may be required.

Q5: What is the impact of the 5 MHz difference in self-resonant frequency?

A: The TYS3010100M-10 has a self-resonant frequency (SRF) of 39 MHz, while the NRH3010T100MN is rated at 34 MHz. Self-resonant frequency defines the upper frequency limit where the inductor behaves as a pure inductance; above this frequency, parasitic capacitance dominates and the component exhibits capacitive behavior. For applications operating below 10 MHz (typical for power conversion, filtering, and energy storage), this 5 MHz difference is not significant. Applications requiring operation near or above 30 MHz should retain the TYS3010100M-10 to maintain predictable inductive behavior.

Q6: Are both parts RoHS3 compliant and suitable for regulated markets?

A: Yes, both the TYS3010100M-10 and NRH3010T100MN are ROHS3 Compliant and REACH Unaffected, meeting regulatory requirements for the European Union and equivalent markets. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling. These compliance characteristics are identical between the primary and substitute parts.

Q7: Which part should be selected for applications requiring the full -40°C to 125°C operating range?

A: The TYS3010100M-10 must be selected for applications requiring operation across the full -40°C to 125°C temperature range. The NRH3010T100MN operates only across -25°C to 120°C, which excludes the lower temperature extreme (-40°C to -25°C) and the upper temperature extreme (120°C to 125°C). Applications with temperature requirements outside the substitute's range cannot use the NRH3010T100MN without thermal performance verification.
