NJM2770M Equivalent & Substitute Parts Reference

Part Overview

The NJM2770M from Nisshinbo Micro Devices Inc. is a linear amplifier IC, classified as a Class AB mono amplifier with an output power of 400mW at 16 Ohms. This device is designed for surface-mount applications and features standby and thermal protection. Its operational voltage range is 2V to 4.5V, with an operating temperature from -40°C to 85°C. The supplier package is 8-DMP (8-SOIC), and it is RoHS non-compliant. The NJM2770M is currently marked as Obsolete, making it necessary to identify direct equivalent or substitute models to maintain design continuity, address ongoing supply, and ensure support for repair or new builds.

Key Parameters

Substitute Part Grouping Explanation

The substitute part must match critical electrical and mechanical parameters to be a valid replacement within the linear amplifier IC category. Only parts that maintain equivalence in supplier, type (Class AB), channel configuration (Mono, 1-Channel), maximum output power, supply voltage range, features (standby, thermal protection), mounting type, operating temperature, and moisture sensitivity level are valid substitutes. The package type is also compared; differences are only indicated where provided and do not impact electrical function per the data provided. RoHS status is included for compliance evaluation.

Parameter Comparison

Engineering Selection Recommendations

The main part NJM2770M is listed as Obsolete and is RoHS non-compliant. The substitute NJM2770RB1-TE1# is marked as Active and RoHS Compliant. Both parts share identical suppliers, electrical parameters, features, mounting type, temperature range, and moisture sensitivity level. The package and RoHS status are differentiators. Selection should be based on required compliance criteria and compatibility with PCB footprint and design requirements as defined by the provided package information.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to select a substitute for the NJM2770M?
A1: Substitutes are selected based on identical manufacturer, functional type (Class AB amplifier), channel configuration (1-Channel Mono), maximum output power, supply voltage, integrated features, operating temperature range, mounting type, and moisture sensitivity level.

Q2: What are the differences in package types between NJM2770M and NJM2770RB1-TE1#?
A2: NJM2770M uses an 8-DMP (8-SOIC, 0.209" width) package. NJM2770RB1-TE1# uses an 8-TVSP (8-VSSOP, 8-MSOP, 0.110" width) package. These differences must be considered for mechanical compatibility.

Q3: Are there differences in environmental compliance status?
A3: NJM2770M is RoHS non-compliant. NJM2770RB1-TE1# is RoHS Compliant. This difference impacts selection for designs requiring environmental compliance.

Q4: Is direct electrical equivalence ensured between NJM2770M and NJM2770RB1-TE1#?
A4: Both parts provide matching key electrical specifications as outlined in the parameter comparison table.

Q5: How is inventory status relevant to selection?
A5: NJM2770M is Obsolete, while NJM2770RB1-TE1# is Active. Continuity of supply may necessitate use of the active substitute.
