Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and ROHS3 compliance, qualifying them for equivalent substitution in applications requiring 1.8 µH inductance at 300 mA.

36502C1R8JTDG (TE Connectivity): This substitute carries AEC-Q200 automotive qualification, providing additional reliability assurance for automotive and high-reliability applications. Physical height is reduced to 2.10mm maximum, offering improved PCB clearance compared to the original part.

LQW2UAS1R8J00L (Murata): This substitute features an extended operating temperature range of -55°C ~ 125°C, supporting applications requiring lower temperature operation. The air core construction differs from the ceramic core of the original part. Physical dimensions are the smallest among the three options (2.62mm x 2.45mm length and width, 2.03mm height maximum), providing maximum PCB space efficiency.

All substitute parts satisfy the core electrical parameters, package requirements, and environmental compliance specifications of the AISC-1008-1R8J-T.

Frequently Asked Questions (FAQ)

Q: Can the 36502C1R8JTDG replace the AISC-1008-1R8J-T in all applications?

A: Yes, the 36502C1R8JTDG meets all electrical and mechanical specifications of the AISC-1008-1R8J-T. The AEC-Q200 rating provides additional qualification for automotive environments. Physical height is 0.007" (0.19mm) lower, which may be advantageous in space-constrained designs.

Q: What is the difference between the ceramic core and air core inductors?

A: The AISC-1008-1R8J-T and 36502C1R8JTDG use ceramic core construction, while the LQW2UAS1R8J00L uses air core construction. Both achieve the same inductance value and electrical characteristics specified in this comparison. Core material selection affects frequency response characteristics and self-resonant frequency, which differ among the three parts (120 MHz, 160 MHz, and 140 MHz respectively).

Q: Are there physical dimension constraints when substituting?

A: The LQW2UAS1R8J00L has smaller footprint dimensions (0.103" x 0.096" versus 0.115" x 0.110") and lower seated height (0.080" versus 0.090"). These differences may require PCB layout verification if space is critical. The 36502C1R8JTDG maintains identical footprint dimensions to the original part.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes, all three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity precautions are required during storage or handling.

Q: Which substitute is recommended for extended temperature range applications?

A: The LQW2UAS1R8J00L supports -55°C ~ 125°C operating range, compared to -40°C ~ 125°C for the original and TE Connectivity substitute. This extended lower temperature capability qualifies it for applications requiring operation below -40°C.
