Substitute Part Grouping Explanation

Substitute parts for the HCM0503-5R6-R are classified based on electrical and mechanical compatibility within the following criteria:

Direct Substitutes maintain the core electrical specifications: 5.6 µH inductance at ±20% tolerance, shielded construction, surface mount configuration, and operating temperature range of -55°C to 125°C. These parts are functionally interchangeable when current rating and DC resistance requirements are met or exceeded.

Similar Parts share the same inductance value and shielding characteristics but differ in current rating, DC resistance, or physical dimensions. These parts are suitable for applications where the main part's current handling capability exceeds circuit requirements.

The substitution logic prioritizes:

• Inductance value: 5.6 µH (fixed requirement)
• Inductance tolerance: ±20% (fixed requirement)
• Shielding: Shielded (fixed requirement)
• Current rating: Equal to or greater than 4.3 A for direct substitutes
• DC resistance: Equal to or less than 71 mOhm for direct substitutes
• Operating temperature: -55°C to 125°C minimum
• Mounting type: Surface Mount (fixed requirement)
• RoHS compliance: Required

Parameter Comparison

Engineering Selection Recommendations

IHLP2020CZER5R6M11 (Vishay Dale) qualifies as a direct substitute. This part matches the main component in inductance, tolerance, current rating (4.25 A vs. 4.3 A), DC resistance (70.6 mOhm vs. 71 mOhm maximum), operating temperature range, and RoHS compliance. The molded construction provides equivalent shielding performance. Physical dimensions are slightly larger (5.49 x 5.18 mm vs. 5.15 x 5.10 mm), and height remains at 3.00 mm. ROHS3 compliance exceeds RoHS requirements. This part is available in Cut Tape and Digi-Reel packaging formats.

PA4340.562NLT (Pulse Electronics) qualifies as a direct substitute with enhanced performance characteristics. This part delivers superior DC resistance (63 mOhm vs. 71 mOhm maximum) and higher saturation current (4.5 A vs. 3.5 A). Current rating matches at 4.25 A. The part carries AEC-Q200 automotive qualification and ROHS3 compliance. Operating temperature minimum is -40°C (vs. -55°C for the main part), which is acceptable for most commercial and industrial applications. Physical dimensions are larger (6.00 x 5.40 mm), and height is 3.00 mm. Tape & Reel packaging is standard.

IHLP2020BZER5R6M01 (Vishay Dale) is classified as a similar part suitable for applications where current requirements are lower than 4.3 A. This part delivers lower current rating (2.5 A) and higher DC resistance (122 mOhm), making it unsuitable as a direct replacement for the main component. However, it provides the same inductance, tolerance, shielding, and operating temperature range. Height is reduced to 2.00 mm, which may be advantageous in space-constrained designs. ROHS3 compliance is confirmed.

IHLP2020BZER5R6M11 (Vishay Dale) is classified as a similar part with reduced current handling capability. Current rating is 3.0 A (vs. 4.3 A for the main part) with higher DC resistance (92 mOhm vs. 71 mOhm maximum). This part is suitable only for applications where the main part's current rating exceeds circuit requirements. Inductance, tolerance, shielding, and operating temperature range match the main component. Height is reduced to 2.00 mm. ROHS3 compliance is confirmed.

All substitute parts maintain active product status and unlimited moisture sensitivity rating (MSL 1), ensuring long-term availability and handling compatibility with the main component.

Frequently Asked Questions (FAQ)

Q: Can IHLP2020CZER5R6M11 replace HCM0503-5R6-R in all applications?

A: Yes, IHLP2020CZER5R6M11 is a direct substitute. Both parts share 5.6 µH inductance at ±20% tolerance, shielded construction, 4.25 A current rating (within 0.05 A of the main part's 4.3 A), and maximum DC resistance of 70.6 mOhm (within 0.4 mOhm of the main part's 71 mOhm). Operating temperature ranges and RoHS compliance are equivalent. Physical dimensions are slightly larger, but height remains at 3.00 mm.

Q: What is the key difference between PA4340.562NLT and the main part HCM0503-5R6-R?

A: PA4340.562NLT offers superior DC resistance performance (63 mOhm vs. 71 mOhm maximum) and higher saturation current (4.5 A vs. 3.5 A). The operating temperature minimum is -40°C instead of -55°C. This part includes AEC-Q200 automotive qualification. Physical dimensions are larger (6.00 x 5.40 mm vs. 5.15 x 5.10 mm). All other electrical parameters match the main component.

Q: Why are IHLP2020BZER5R6M01 and IHLP2020BZER5R6M11 classified as similar parts rather than direct substitutes?

A: Both parts have reduced current ratings (2.5 A and 3.0 A respectively) compared to the main part's 4.3 A. IHLP2020BZER5R6M01 has significantly higher DC resistance (122 mOhm vs. 71 mOhm), and IHLP2020BZER5R6M11 has higher DC resistance (92 mOhm vs. 71 mOhm). These parts are suitable only for applications where the main part's current handling capability exceeds circuit requirements. Both offer reduced height (2.00 mm vs. 3.00 mm), which may be beneficial in space-constrained designs.

Q: Are there packaging differences between substitute parts?

A: Yes. The main part HCM0503-5R6-R is supplied in Tape & Reel (TR) format. IHLP2020CZER5R6M11 and IHLP2020BZER5R6M01 are available in Cut Tape (CT) and Digi-Reel® formats. PA4340.562NLT and IHLP2020BZER5R6M11 are supplied in Tape & Reel (TR) format. Packaging format selection depends on assembly equipment compatibility and procurement requirements.

Q: Do all substitute parts meet the same compliance standards as the main component?

A: All substitute parts are RoHS compliant. The main part carries RoHS Compliant status, while all substitutes carry ROHS3 Compliant status, which represents an enhanced compliance level. All parts have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. PA4340.562NLT includes AEC-Q200 automotive qualification, which exceeds standard industrial compliance requirements.

Q: What is the impact of physical dimension differences on PCB layout?

A: The main part measures 5.15 x 5.10 mm with 3.00 mm height. IHLP2020CZER5R6M11 measures 5.49 x 5.18 mm with 3.00 mm height (slightly larger footprint, same height). PA4340.562NLT measures 6.00 x 5.40 mm with 3.00 mm height (larger footprint, same height). IHLP2020BZER5R6M01 and IHLP2020BZER5R6M11 measure 5.49 x 5.18 mm with 2.00 mm height (slightly larger footprint, reduced height). PCB layout verification is required when substituting parts with different dimensions.

Q: Which substitute part offers the best performance for high-current applications?

A: PA4340.562NLT delivers the best performance for high-current applications, with the lowest DC resistance (63 mOhm) and highest saturation current (4.5 A). This part minimizes power dissipation and provides the greatest margin above the main part's 4.3 A current rating. IHLP2020CZER5R6M11 is the second choice, with DC resistance of 70.6 mOhm and saturation current of 3.5 A, matching the main part's saturation specification.

Q: Can substitute parts be used interchangeably in existing designs without circuit modification?

A: Direct substitutes (IHLP2020CZER5R6M11 and PA4340.562NLT) can be used without circuit modification, provided PCB layout accommodates the slightly larger physical dimensions. Similar parts (IHLP2020BZER5R6M01 and IHLP2020BZER5R6M11) require circuit analysis to confirm that reduced current ratings and higher DC resistance values are acceptable for the specific application. All parts maintain the same inductance value and tolerance, ensuring electrical compatibility at the circuit level.
