CA5420AM Equivalent & Substitute Parts

Part Overview

The CA5420AM is a general-purpose operational amplifier manufactured by Renesas Electronics Corporation, housed in an 8-SOIC surface mount package. This device features rail-to-rail output capability and is designed for linear amplification applications requiring low input bias current and moderate bandwidth performance. The CA5420AM is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. Substitute parts must maintain electrical and mechanical compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CA5420AM is determined by strict equivalence across all electrical performance parameters and mechanical compatibility criteria. The substitute part CA5420AMZ maintains identical specifications for amplifier type, circuit count, output configuration, slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current capability, supply voltage range, and operating temperature range. Both parts utilize the same 8-SOIC surface mount package with identical physical dimensions (0.154" width, 3.90mm), ensuring direct mechanical compatibility on printed circuit boards without layout modification.

The primary distinction between the main part and substitute relates to product status and compliance certification. The CA5420AM is classified as obsolete with RoHS non-compliant status, while the CA5420AMZ is active and RoHS3 compliant. The packaging format differs (CA5420AM unspecified versus CA5420AMZ in Tube), and moisture sensitivity levels vary (MSL 1 versus MSL 3). These differences do not affect electrical performance or functional substitution capability.

Parameter Comparison

Engineering Selection Recommendations

The CA5420AMZ serves as the direct functional equivalent and recommended substitute for the obsolete CA5420AM. All electrical performance parameters are identical, and the 8-SOIC surface mount package dimensions are equivalent, permitting direct board-level substitution without circuit redesign or layout modification.

Selection of CA5420AMZ is supported by its active product status, ensuring long-term availability and supply chain continuity. The part meets ROHS3 compliance requirements, satisfying environmental and regulatory standards applicable to current manufacturing and distribution. The CA5420AMZ is supplied in Tube packaging format, which is standard for production quantities and automated assembly processes.

For applications subject to RoHS compliance mandates or environmental regulations, CA5420AMZ is the appropriate selection. For legacy systems or applications where RoHS compliance is not required, the CA5420AM remains functionally equivalent, though availability is limited due to obsolete status.

Frequently Asked Questions (FAQ)

Q: Can CA5420AMZ be used as a direct replacement for CA5420AM in existing designs?

A: Yes. The CA5420AMZ is electrically and mechanically equivalent to the CA5420AM. All performance parameters, including slew rate, gain bandwidth product, input bias current, supply voltage range, and operating temperature range, are identical. The 8-SOIC package dimensions are the same, permitting direct substitution without circuit modification or board redesign.

Q: What is the primary reason to transition from CA5420AM to CA5420AMZ?

A: The CA5420AM is classified as obsolete, creating supply and availability constraints. The CA5420AMZ is an active product with confirmed long-term availability. Additionally, CA5420AMZ meets ROHS3 compliance standards, whereas CA5420AM is RoHS non-compliant. For new designs and ongoing production, CA5420AMZ is the recommended selection.

Q: Are there differences in moisture sensitivity between these parts?

A: Yes. The CA5420AM has MSL 1 (Unlimited), while CA5420AMZ has MSL 3 (168 Hours). MSL 3 requires controlled storage and handling conditions with a maximum floor life of 168 hours after bag opening. Standard moisture control procedures for surface mount components apply to CA5420AMZ.

Q: Does the packaging format affect electrical performance?

A: No. The packaging format (Tube for CA5420AMZ) is a supply and handling specification only. It does not affect electrical characteristics, performance parameters, or functional operation. The component itself remains identical.

Q: Are both parts suitable for the full operating temperature range of -55°C to 125°C?

A: Yes. Both CA5420AM and CA5420AMZ are rated for operation across the full temperature range of -55°C to 125°C. Performance parameters remain consistent throughout this range.

Q: What supply voltage range is supported by these parts?

A: Both parts support a supply voltage range of 2 V to 20 V, providing flexibility for single-supply and dual-supply configurations across a wide range of applications.
