Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLC450JB-0R022 is determined by the following critical parameters:

• Resistance Value: Must be 22 mOhms
• Tolerance: Must be ±5%
• Composition: Must be Wirewound
• Package Type: Must be Axial with 2 terminations
• Operating Temperature Range: Must support -55°C ~ 250°C
• Power Rating: Must be equal to or greater than 4.5W
• Compliance: Must maintain ROHS3 compliance

The SQPW5R022J from TE Connectivity Passive Product meets all substitution criteria with a higher power rating of 5W, providing additional thermal margin while maintaining identical electrical specifications and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the LLC450JB-0R022 and SQPW5R022J are Active products with full ROHS3 and REACH compliance. The SQPW5R022J provides a 0.5W power rating advantage over the primary part while maintaining identical electrical characteristics and mechanical form factor. Selection between these parts should be based on availability, lead time, and application thermal requirements. The higher power rating of the SQPW5R022J offers improved thermal headroom in power-dissipation-critical applications without compromising any electrical or mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can SQPW5R022J replace LLC450JB-0R022 in existing designs? A: Yes. Both parts share identical resistance values, tolerance, composition, package type, and operating temperature range. The SQPW5R022J's 5W rating exceeds the 4.5W requirement, making it a direct substitute.

Q: Are there dimensional differences between these parts? A: Both parts use axial packaging with 2 terminations. The LLC450JB-0R022 measures 0.709" L x 0.252" W (18.00mm x 6.40mm). The SQPW5R022J measures 0.394" x 0.354" Rectangular x 0.866" L (10.00mm x 9.00mm x 22.00mm). Verify PCB layout compatibility before substitution.

Q: Do both parts meet the same compliance standards? A: Yes. Both are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements.

Q: What is the temperature coefficient difference? A: The LLC450JB-0R022 does not specify a temperature coefficient. The SQPW5R022J specifies ±300ppm/°C. This additional specification in the substitute part provides better temperature stability documentation.

Q: Are there feature differences? A: The SQPW5R022J includes Flame Proof, Moisture Resistant, and Safety features. The LLC450JB-0R022 does not specify these features. These additional characteristics in the substitute part enhance reliability in demanding environments.
