Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the PD54R-103K is determined by the following critical parameters:

• Inductance Value: 10 µH ±10% tolerance required
• Current Rating (Isat): Minimum 1.44 A saturation current
• DC Resistance (DCR): Electromagnetic efficiency and thermal performance; lower or comparable values preferred
• Core Construction: Ferrite unshielded drum core wirewound type
• Package Type: Nonstandard surface mount footprint
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• Regulatory Compliance: RoHS3 compliance required; REACH unaffected status

The SDR0604-100KL from Bourns Inc. qualifies as an equivalent substitute based on matching inductance value, tolerance, core type, package classification, and regulatory compliance. The operating temperature range of -40°C ~ 125°C provides coverage for the specified thermal envelope with reduced lower-temperature capability.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (PD54R-103K): Select for applications requiring the full operating temperature range of -55°C ~ 125°C. Both parts carry active product status and RoHS3 compliance, supporting long-term availability and regulatory adherence.

Substitute Part (SDR0604-100KL): Select when procurement flexibility is required or when the primary part inventory is constrained. The operating temperature range begins at -40°C; applications operating at temperatures below -40°C require the primary part. Both parts are manufactured by established suppliers with active product status, ensuring equivalent compliance certifications and reliability characteristics.

Frequently Asked Questions (FAQ)

Q: What are the critical differences between PD54R-103K and SDR0604-100KL?

A: Both inductors provide 10 µH inductance with ±10% tolerance and ferrite unshielded drum core construction. The primary difference is the lower operating temperature limit: PD54R-103K operates to -55°C, while SDR0604-100KL operates to -40°C. The SDR0604-100KL does not specify DC Resistance and current rating parameters in the available data.

Q: Can SDR0604-100KL replace PD54R-103K in all applications?

A: Substitution is suitable for applications where the operating temperature range does not extend below -40°C and where unspecified DC Resistance and current rating parameters are acceptable. For cryogenic or extended low-temperature environments, the PD54R-103K is the required selection.

Q: Are both parts compatible with the same footprint?

A: Both parts utilize nonstandard surface mount packages with comparable dimensions: PD54R-103K (5.70mm × 5.11mm × 4.50mm) and SDR0604-100KL (5.80mm dia × 4.80mm). Verification against specific PCB layout and schematic requirements is necessary prior to final selection.

Q: Do both parts meet regulatory requirements?

A: Both parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings. Both support equivalent environmental and regulatory compliance profiles.

Q: At what frequency are these inductance values specified?

A: Both inductors are characterized at 1 kHz test frequency for inductance verification and tolerance confirmation.
