Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPD127R-222M is determined by the following critical parameters:

Electrical Parameters:

• Inductance value: 2.2 µH (±20% tolerance)
• Current rating: minimum 8.5 A continuous
• DC resistance: maximum 15 mOhm
• Core material: Ferrite
• Shielding requirement: Shielded

Mechanical Parameters:

• Mounting type: Surface Mount
• Package type: Nonstandard drum core
• Operating temperature range: -55°C to 125°C minimum

Compliance Parameters:

• RoHS3 compliance required
• REACH unaffected status

The substitute part B82477G4222M000 meets the core electrical specifications of 2.2 µH inductance with ferrite shielded drum core construction and surface mount configuration. Both parts operate within the same temperature range and maintain ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

SPD127R-222M (API Delevan Inc.) is the primary component specification. This part is Active in product status with ROHS3 compliance and REACH unaffected designation, confirming regulatory compliance for current applications.

B82477G4222M000 (EPCOS - TDK Electronics) is an equivalent substitute meeting the same inductance value, core material, shielding configuration, and operating temperature range. This part is also Active in product status with identical ROHS3 and REACH compliance certifications.

Selection between these parts is based on:

1. Availability and lead time - Both parts are in stock with active manufacturing status
2. DC resistance performance - B82477G4222M000 offers lower maximum DC resistance (10 mOhm vs. 15 mOhm), resulting in reduced power dissipation
3. Saturation current - B82477G4222M000 provides higher saturation current (11 A vs. 8.5 A), offering additional margin in transient conditions
4. Physical dimensions - B82477G4222M000 has slightly larger footprint (12.80mm vs. 12.00mm); verify PCB layout compatibility
5. Continuous current rating - SPD127R-222M rated at 8.5 A continuous; B82477G4222M000 rated at 8 A continuous; application current requirements determine suitability

Both parts maintain equivalent electrical performance for 2.2 µH inductance applications within the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can B82477G4222M000 directly replace SPD127R-222M in existing designs?

A: Both parts share identical inductance (2.2 µH), tolerance (±20%), core material (ferrite), shielding (shielded), mounting type (surface mount), and operating temperature range (-55°C to 125°C). Physical dimensions differ slightly (12.80mm vs. 12.00mm); verify PCB layout clearance before substitution. Continuous current rating differs (8 A vs. 8.5 A); confirm application current requirements do not exceed 8 A for the substitute part.

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

A: The primary electrical differences are DC resistance and saturation current. SPD127R-222M specifies 15 mOhm maximum DC resistance and 8.5 A saturation current. B82477G4222M000 specifies 10 mOhm maximum DC resistance and 11 A saturation current. Both maintain 2.2 µH inductance at 100 kHz test frequency with ±20% tolerance.

Q: Are both parts RoHS and REACH compliant?

A: Both SPD127R-222M and B82477G4222M000 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the significance of the size difference between these parts?

A: SPD127R-222M measures 12.00mm x 12.00mm while B82477G4222M000 measures 12.80mm x 12.80mm. Both share identical height (8.00mm maximum seated). The larger footprint of the substitute part requires verification against PCB layout constraints and available board space before implementation.

Q: Which part should be selected for new designs?

A: Selection depends on application-specific requirements. For applications requiring maximum continuous current capacity, SPD127R-222M (8.5 A rating) is appropriate. For applications prioritizing lower DC resistance and higher saturation margin, B82477G4222M000 is suitable. Both parts are Active in product status with equivalent compliance certifications.
