Engineering Selection Recommendations

The MR082C105KAA serves as a direct electrical and mechanical substitute for the obsolete HT08DW105KN. Both components share identical capacitance, tolerance, voltage rating, temperature coefficient, and lead spacing specifications.

Critical Consideration: The MR082C105KAA operates to a maximum temperature of 125°C, whereas the HT08DW105KN extends to 200°C. Applications requiring sustained operation above 125°C cannot use this substitute without thermal performance verification against specific circuit requirements.

Compliance Note: The MR082C105KAA is RoHS non-compliant and REACH-affected. Design teams must confirm compatibility with applicable regulatory requirements before implementation.

Availability: The MR082C105KAA is currently in active production with documented inventory availability, providing supply continuity for the obsolete HT08DW105KN.

Frequently Asked Questions (FAQ)

Q: Can the MR082C105KAA replace the HT08DW105KN in all applications?

A: The MR082C105KAA is electrically and mechanically equivalent for applications operating within -55°C to 125°C. Applications requiring operation above 125°C require alternative solutions.

Q: What are the physical dimension differences between these parts?

A: The MR082C105KAA is slightly smaller (0.490" L x 0.240" W versus 0.500" L x 0.270" W). Lead spacing remains identical at 0.400". Both parts fit standard through-hole PCB layouts designed for radial ceramic capacitors.

Q: Are there compliance differences between these parts?

A: The MR082C105KAA is RoHS non-compliant and REACH-affected. The HT08DW105KN compliance status is not specified in available documentation. Confirm regulatory requirements for your application.

Q: What is the inventory status for each part?

A: HT08DW105KN: 1,096 pieces available (obsolete status). MR082C105KAA: 907 pieces available (active production).
