Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly by matching core electrical and mechanical parameters within the RF MOSFET LDMOS category. Allowed parameters for substitution include: technology type (LDMOS), manufacturer, operating frequency range, gain, voltage test condition, output power, rated voltage, mounting type, and package/case compatibility. Any substitute part must meet or exceed these criteria as explicitly stated.

Parameter Comparison

Engineering Selection Recommendations

The BLF2425M7LS100U is designated as obsolete. The substitute part BLF2425M9LS140U is currently active and ROHS3 compliant, with REACH unaffected and a matching MSL 1 (Unlimited) rating for handling. Both parts share identical package types and mounting styles, supporting direct substitution from a compliance and physical compatibility perspective.

Frequently Asked Questions (FAQ)

Q1: What criteria must be satisfied to constitute a valid substitute for BLF2425M7LS100U?
A: Substitute parts must match technology (LDMOS), manufacturer, test voltage, rated voltage, mechanical mounting type, package/case, and moisture sensitivity level.

Q2: Is package compatibility assured between BLF2425M7LS100U and BLF2425M9LS140U?
A: Both utilize the SOT-502B package and chassis mount, supporting direct mechanical interchangeability.

Q3: Are there compliance or regulatory differences between the main and substitute models?
A: The substitute part BLF2425M9LS140U is ROHS3 compliant and REACH unaffected, and features MSL 1 (Unlimited), aligning with standard handling and environmental requirements.

Q4: How do changes in gain or output power affect suitability for substitution?
A: Engineering selection is based strictly on provided parameters. Differences in gain (18dB vs 19dB) and output power (20W vs 140W) should be evaluated based on system design requirements.

Q5: Why is substitution necessary for BLF2425M7LS100U?
A: The main model is obsolete; sourcing substitutes ensures continued availability and compatibility within existing designs.
