Substitute Part Grouping Explanation

Substitution of the SRP0510-2R2K is determined by the following critical parameters:

Electrical Compatibility Requirements:

  • Inductance value must equal 2.2 µH with ±10% tolerance
  • Shielding type must be shielded
  • Core material must be metal
  • Operating temperature range must encompass -40°C to 125°C
  • Inductance test frequency must be 100 kHz

Mechanical Compatibility Requirements:

  • Mounting type must be surface mount
  • Physical footprint dimensions must be 5.40mm L x 5.10mm W
  • Package case type must be nonstandard

Regulatory Compliance Requirements:

  • RoHS3 compliance required
  • REACH unaffected status required
  • Moisture sensitivity level must be 1 (Unlimited)

The SRP0512-2R2K qualifies as a substitute part because it maintains identical inductance, tolerance, shielding, core material, operating temperature range, mounting type, and physical footprint dimensions. The substitute part demonstrates improved electrical performance through higher current rating and lower DC resistance, with maintained regulatory compliance.

Engineering Selection Recommendations

The SRP0512-2R2K serves as a direct substitute for the SRP0510-2R2K based on electrical and mechanical parameter alignment. Both components maintain identical inductance values, tolerance specifications, shielding characteristics, and operating temperature ranges. The physical footprint dimensions are identical, ensuring PCB layout compatibility.

The SRP0512-2R2K demonstrates enhanced performance characteristics with increased current rating (4.2 A versus 3.4 A) and reduced DC resistance (51.5mOhm versus 75mOhm). These improvements result in lower power dissipation and higher current handling capacity within the same physical package envelope.

Both components satisfy identical regulatory requirements: ROHS3 compliance, REACH unaffected status, and moisture sensitivity level 1. The substitute part carries Last Time Buy status, indicating limited future availability.

The maximum seated height difference of 0.20mm (1.20mm versus 1.00mm) must be evaluated against specific PCB clearance constraints in the target application.

Frequently Asked Questions (FAQ)

Q: Can the SRP0512-2R2K replace the SRP0510-2R2K in existing designs?

A: Yes. Both components share identical inductance values (2.2 µH), tolerance (±10%), shielding type, core material, operating temperature range, and physical footprint dimensions (5.40mm x 5.10mm). The substitute part is electrically and mechanically compatible for direct substitution.

Q: What are the key differences between these two parts?

A: The SRP0512-2R2K provides higher current rating (4.2 A versus 3.4 A), higher saturation current (6.8A versus 5A), and lower DC resistance (51.5mOhm versus 75mOhm). The seated height is 0.20mm greater (1.20mm versus 1.00mm). Both parts maintain identical inductance and regulatory compliance.

Q: Are there packaging differences between these parts?

A: The SRP0510-2R2K is supplied in standard packaging, while the SRP0512-2R2K is supplied in Tape & Reel (TR) format. Both are surface mount components with identical footprint dimensions.

Q: Does the height difference affect PCB compatibility?

A: The SRP0512-2R2K maximum seated height is 1.20mm compared to 1.00mm for the SRP0510-2R2K. This 0.20mm difference must be evaluated against specific PCB clearance requirements, component stacking constraints, and enclosure height limitations in the target application.

Q: Are both parts RoHS compliant?

A: Yes. Both the SRP0510-2R2K and SRP0512-2R2K are ROHS3 compliant and REACH unaffected, with moisture sensitivity level 1 (Unlimited).

Q: What is the significance of the product status difference?

A: The SRP0510-2R2K carries Obsolete status, indicating discontinued production. The SRP0512-2R2K carries Last Time Buy status, indicating limited remaining availability. For new designs or long-term production requirements, component availability should be confirmed with the supplier.
