PD54R-104K Equivalent & Substitute Parts

Part Overview

The PD54R-104K is a 100 µH unshielded drum core wirewound inductor manufactured by API Delevan Inc., designed for surface mount applications. This component operates at 520 mA rated current with a maximum DC resistance of 700 mOhm and functions across the temperature range of -55°C to 125°C. The part is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across critical parameters including inductance value, current rating, DC resistance, core material, shielding configuration, and mounting type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PD54R-104K is determined by strict equivalence across the following parameters:

Electrical Parameters:

• Inductance value: 100 µH ±10%
• Current rating: minimum 520 mA
• DC resistance: maximum 700 mOhm
• Core material: Ferrite
• Shielding configuration: Unshielded

Mechanical Parameters:

• Mounting type: Surface Mount
• Package classification: Nonstandard drum core form factor
• Temperature operating range: compatible with -55°C to 125°C minimum

Compliance Parameters:

• RoHS3 compliance required
• MSL rating: 1 (Unlimited)

The SDR0604-101KL from Bourns Inc. meets all substitution criteria across these parameters, maintaining functional equivalence while offering alternative sourcing and inventory availability.

Engineering Selection Recommendations

PD54R-104K Selection Criteria:

• Required when operating temperature minimum of -55°C is mandatory
• Preferred for applications requiring the full -55°C to 125°C temperature envelope
• Active product status with established supply chain through API Delevan Inc.

SDR0604-101KL Selection Criteria:

• Suitable for applications with minimum operating temperature of -40°C or higher
• Offers higher saturation current (680 mA vs. 520 mA), providing additional margin in current-limited applications
• Active product status with higher inventory availability (9037 Pcs vs. 895 Pcs)
• Equivalent electrical and mechanical performance within the overlapping temperature range (-40°C to 125°C)
• ROHS3 compliant with identical MSL rating

Both parts maintain Active product status and full regulatory compliance. Selection between these parts depends on specific application temperature requirements and inventory availability constraints.

Frequently Asked Questions (FAQ)

Q: Can SDR0604-101KL replace PD54R-104K in all applications?

A: SDR0604-101KL is functionally equivalent for applications operating within -40°C to 125°C. Applications requiring operation below -40°C must use PD54R-104K to maintain the -55°C minimum temperature specification.

Q: What are the physical dimension differences between these parts?

A: PD54R-104K dimensions are 0.224" L × 0.201" W × 0.177" H (5.70mm × 5.11mm × 4.50mm). SDR0604-101KL dimensions are 0.228" L × 0.228" W × 0.189" H (5.80mm × 5.80mm × 4.80mm). Both are nonstandard drum core packages. Verify PCB layout clearances before substitution.

Q: Are the inductance values and tolerances identical?

A: Yes. Both parts specify 100 µH with ±10% tolerance, measured at 1 kHz. Inductance performance is equivalent.

Q: What is the difference in saturation current between these parts?

A: PD54R-104K has saturation current of 520 mA. SDR0604-101KL has saturation current of 680 mA. Both meet the 520 mA rated current requirement. The higher saturation rating on the Bourns part provides additional design margin.

Q: Are both parts RoHS3 compliant?

A: Yes. Both PD54R-104K and SDR0604-101KL are ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity).

Q: Which part should be selected for new designs?

A: Selection depends on application temperature range. For designs requiring -55°C operation, use PD54R-104K. For designs operating at -40°C or above, either part is acceptable; SDR0604-101KL offers higher inventory availability and increased saturation current margin.
