Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SDS680R-154M are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Primary Matching Parameters:

• Inductance value: 150 µH
• Inductance tolerance: ±20%
• Current rating: 260 mA minimum
• DC resistance: 590 mOhm maximum
• Shielding: Shielded configuration required
• Core type: Drum core wirewound construction
• Mounting: Surface mount
• Physical footprint: 0.260" L x 0.175" W x 0.115" H maximum
• Inductance test frequency: 100 kHz

Compliance Parameters:

• RoHS3 compliance required
• MSL rating: 1 (Unlimited) acceptable
• Operating temperature range: minimum -40°C ~ 85°C

The substitute part 74451215 from Würth Elektronik meets all primary electrical parameters and physical dimensions. Variations in self-resonant frequency and saturation current do not disqualify substitution when the primary electrical specifications are matched.

Parameter Comparison

Engineering Selection Recommendations

SDS680R-154M (API Delevan Inc.) is the primary component specification. This part is Active product status with full RoHS3 compliance and MSL 1 rating, suitable for unrestricted moisture environments. The operating temperature range of -40°C ~ 85°C defines the thermal envelope for applications.

74451215 (Würth Elektronik WE-PD3 Series) is a functionally equivalent substitute. All critical electrical parameters match the primary part: 150 µH inductance at ±20% tolerance, 260 mA current rating, and 590 mOhm maximum DC resistance. Physical dimensions and mounting characteristics are identical. The substitute part is also Active status with RoHS3 compliance and MSL 1 rating.

The substitute part provides an extended operating temperature range of -40°C ~ 125°C, which exceeds the primary part specification. The self-resonant frequency differs (6 MHz versus 9 MHz), and saturation current is specified for the substitute (50 mA) but not for the primary part. These variations do not affect substitution validity when the primary electrical specifications are met.

Selection between these parts should be based on availability, supply chain requirements, and design thermal environment. Both parts are suitable for identical circuit applications within the specified operating temperature range of the primary part.

Frequently Asked Questions (FAQ)

Q: Can 74451215 be used as a direct replacement for SDS680R-154M?

A: Yes. The 74451215 meets all critical electrical specifications: 150 µH inductance, ±20% tolerance, 260 mA current rating, 590 mOhm maximum DC resistance, and shielded drum core construction. Physical dimensions and surface mount packaging are identical. Both parts are RoHS3 compliant with MSL 1 rating.

Q: What are the key differences between these parts?

A: The primary differences are manufacturer (API Delevan versus Würth Elektronik) and self-resonant frequency (9 MHz versus 6 MHz). The substitute part specifies saturation current at 50 mA, while the primary part does not provide this parameter. The substitute part has an extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C).

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions: 0.260" L x 0.175" W x 0.115" H (6.60mm x 4.45mm x 2.92mm). Both use nonstandard surface mount packages and are suitable for identical PCB footprints.

Q: Do both parts have the same compliance certifications?

A: Yes. Both SDS680R-154M and 74451215 are RoHS3 compliant, REACH unaffected, and have MSL 1 (Unlimited) moisture sensitivity ratings. Both are classified as Active product status.

Q: What is the inductance tolerance for both parts?

A: Both parts have ±20% inductance tolerance at 100 kHz test frequency. The nominal inductance value is 150 µH for both.

Q: Can these parts be used interchangeably in high-temperature applications?

A: The primary part SDS680R-154M is rated to 85°C maximum. The substitute 74451215 is rated to 125°C maximum. For applications requiring operation above 85°C, the substitute part provides extended thermal capability. For applications within the 85°C limit, both parts are suitable.

Q: What is the DC resistance specification?

A: Both parts have a maximum DC resistance of 590 mOhm. This specification is critical for applications where resistive losses must be minimized.

Q: Are these parts available in tape and reel packaging?

A: Yes. Both SDS680R-154M and 74451215 are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
