Substitute Part Grouping Explanation

Substitution of the LM4836MTE/NOPB is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

Identical Class AB amplifier topology
Matching 2-Channel stereo output configuration with stereo headphone capability
Identical output power specifications: 2.2W x 2 @ 3Ohm and 95mW x 2 @ 32Ohm
Identical supply voltage range: 2.7V ~ 5.5V
Identical operating temperature range: -40°C ~ 85°C
Identical integrated feature set: Bass Boost, Depop, Input Multiplexer, Mute, Shutdown, Thermal Protection, Volume Control

Mechanical Equivalence Criteria:

Identical package type: 28-PowerTSSOP
Identical pin count and footprint
Surface mount configuration

Compliance Equivalence Criteria:

ROHS3 compliance maintained
MSL rating of 1 or better
REACH unaffected status

The LM4836MTEX/NOPB meets all substitution criteria as a direct equivalent, with the primary distinction being packaging format (Tape & Reel versus individual units) and product status (Active versus Obsolete).
