PD54R-102M Equivalent & Substitute Parts

Part Overview

The PD54R-102M is a 1 µH unshielded drum core wirewound inductor manufactured by API Delevan Inc., designed for surface mount applications. This fixed inductor features a ferrite core with a current rating of 2.9 A and a maximum DC resistance of 50 mOhm. The component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PD54R-102M is based on the following critical parameters:

Primary Matching Criteria:

• Inductance value: 1 µH
• Inductance tolerance: ±20%
• Core type: Ferrite, unshielded drum core
• Mounting type: Surface Mount (SMD)
• RoHS3 compliance status

Secondary Compatibility Factors:

• Current saturation rating (minimum 2.9 A required)
• DC resistance (maximum 50 mOhm preferred)
• Operating temperature range overlap
• Package classification: Nonstandard

The SDR0604-1R0ML from Bourns Inc. meets the primary matching criteria with identical inductance, tolerance, core material, and mounting configuration. Both components are Active status products with RoHS3 compliance and Tape & Reel packaging.

Engineering Selection Recommendations

PD54R-102M Selection Criteria:

• Applications requiring extended low-temperature operation below -40°C
• Designs with specified DC resistance requirements of 50 mOhm maximum
• Systems where current saturation specification of 2.9 A is critical
• Established supply chain with 631 units in stock

SDR0604-1R0ML Selection Criteria:

• Applications operating within -40 to 125°C temperature range
• Designs where current saturation and DC resistance specifications are not explicitly required
• Supply chain flexibility with 2254 units in stock
• Equivalent RoHS3 compliance and Active product status

Both components satisfy core electrical requirements for 1 µH inductance with ±20% tolerance in unshielded ferrite drum core configuration. Selection between these parts depends on specific application temperature requirements and whether DC resistance and current saturation parameters are design constraints.

Frequently Asked Questions (FAQ)

Q: Can SDR0604-1R0ML replace PD54R-102M in all applications?

A: SDR0604-1R0ML matches the primary electrical specifications (1 µH inductance, ±20% tolerance, ferrite unshielded core, surface mount). However, applications requiring operation below -40°C or with explicit DC resistance and current saturation specifications should retain PD54R-102M. The SDR0604-1R0ML does not provide published DC resistance or current saturation values.

Q: What are the physical dimension differences?

A: PD54R-102M dimensions are 5.70mm L × 5.11mm W × 4.50mm H. SDR0604-1R0ML dimensions are 5.80mm L × 5.80mm W × 4.80mm H. Both are classified as Nonstandard package types. PCB layout and clearance requirements should be verified for each component.

Q: Are both parts RoHS3 compliant?

A: Yes. Both PD54R-102M and SDR0604-1R0ML are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited) and REACH Unaffected status.

Q: What is the inductance test frequency for each part?

A: PD54R-102M inductance is tested at 7.96 MHz. SDR0604-1R0ML inductance is tested at 1 kHz. This difference in test frequency may result in minor inductance value variations depending on frequency-dependent core behavior.

Q: Which part should be selected for new designs?

A: Both components are Active status products suitable for new designs. Selection should be based on specific application requirements for operating temperature range, DC resistance tolerance, and current saturation specifications. Verify that unspecified parameters for SDR0604-1R0ML meet design margins.
