Equivalent & Substitute Parts Reference: BA4558N

Part Overview

The Rohm Semiconductor BA4558N is a general purpose operational amplifier IC designed with 2 amplification circuits in an 8-SIP through-hole package. It features essential specifications such as a slew rate of 1.2V/µs, gain bandwidth product of 2 MHz, input bias current of 60 nA, and input offset voltage of 500 µV. The BA4558N is classified as obsolete, necessitating the identification of substitute models with matching electrical and mechanical parameters to ensure continued availability, compliance, and functional equivalence in designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection is strictly governed by the following parameters: amplifier type, number of amplification circuits, slew rate, gain bandwidth product, input bias current, input offset voltage, output current per channel, supply voltage range (minimum and maximum), operating temperature range, mounting type, package/case, RoHS compliance, Moisture Sensitivity Level (MSL), REACH status, and product availability status. Only parts matching these fields can be considered substitutes for the BA4558N within the linear amplifier category.

Parameter Comparison

Engineering Selection Recommendations

Selection between BA4558N and BA4558F-E2 should be based on product status (obsolete versus active), RoHS compliance, and REACH status as provided. Both parts are ROHS3 compliant, have MSL 1 (Unlimited), and are unaffected by REACH, meeting environmental and regulatory requirements. Package and mounting type must align with application constraints.

Frequently Asked Questions (FAQ)

Q1: What are the essential parameters for substituting BA4558N?
A1: Substitute suitability is determined by amplifier type, number of circuits, slew rate, gain bandwidth product, input bias current, input offset voltage, output current per channel, supply voltage range, operating temperature range, mounting type, package/case, product status, RoHS status, Moisture Sensitivity Level (MSL), and REACH status.

Q2: Is BA4558F-E2 functionally compatible with BA4558N?
A2: BA4558F-E2 matches all provided electrical parameters and compliance ratings. The key difference is in mounting type and package/case.

Q3: How does package or mounting type affect substitution?
A3: BA4558N uses an 8-SIP through-hole package, while BA4558F-E2 features an 8-SOIC surface-mount package. Mechanical and layout considerations must be factored into selection.

Q4: Are compliance and certifications equivalent between these models?
A4: Both BA4558N and BA4558F-E2 are ROHS3 compliant, MSL 1 (Unlimited), and REACH unaffected.

Q5: Can parts with different package types be substituted directly?
A5: Package differences impact mechanical interchangeability. Substitution is possible only if the system design accommodates the mounting and package variations.
