Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped strictly according to matching key electrical parameters (technology, frequency, gain, test voltage, current, output power, and rated voltage), and identical mechanical criteria (mounting type and package). All substitute candidates must be based on LDMOS technology, operate in the specified frequency range, provide comparable gain and output power, utilize test and rated voltages as specified, and be supplied in SOT502B for chassis mounting. Additional compliance criteria such as Moisture Sensitivity Level and REACH Status are included to ensure compatibility in regulated applications.

Parameter Comparison

Engineering Selection Recommendations

BLF2425M7LS100J is assigned obsolete status; therefore, substitution with an active part is necessary to ensure continuity of supply and production. BLF2425M9LS140J, produced by Ampleon USA Inc., shares identical package, mounting type, base product number, and compliance as demonstrated by identical Moisture Sensitivity Level and REACH status. The substitute is designated as ROHS3 compliant and is currently active in production with available inventory.

Frequently Asked Questions (FAQ)

Q: What are the critical matching criteria for substituting BLF2425M7LS100J?
A: Substitution requires identical technology, frequency range, gain, test and rated voltages, output power, mounting type, package, and compliance statuses such as Moisture Sensitivity Level and REACH.

Q: Can BLF2425M9LS140J be directly used in the same chassis and PCB layout as BLF2425M7LS100J?
A: Both devices utilize the SOT-502B package and identical mounting type, providing direct mechanical compatibility.

Q: Is there any difference in regulatory compliance between the original and the substitute part?
A: Both are classified as Moisture Sensitivity Level 1 (Unlimited) and REACH Unaffected. BLF2425M9LS140J also carries ROHS3 compliance.

Q: Does the status of the original part affect engineering selection?
A: The original part is marked obsolete, making selection of an active substitute necessary for procurement and manufacturing continuity.

Q: How is the substitute part grouped for engineering qualification?
A: Grouping is based strictly on matching electrical and mechanical parameters, product compliance, and package compatibility as detailed above.
