CA3130AM Equivalent & Substitute Parts

Part Overview

The CA3130AM is a general-purpose operational amplifier manufactured by Renesas Electronics Corporation, housed in an 8-SOIC surface mount package. This device is classified as obsolete, indicating discontinued production and limited availability. The CA3130AM serves applications requiring low input bias current, moderate bandwidth, and operation across extended temperature ranges. Due to its obsolete status, identifying equivalent substitute parts with identical electrical and mechanical specifications is essential for design continuity and procurement planning.

Substitute Part Grouping Explanation

Substitution of the CA3130AM is determined by strict equivalence across all electrical performance parameters and mechanical compatibility criteria. The substitute part CA3130AMZ maintains identical specifications for 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 share the same base product number (CA3130), amplifier type classification, circuit count, and 8-SOIC package geometry. The primary distinction between these parts is product status and packaging format: the CA3130AM is obsolete with tape packaging, while the CA3130AMZ is active with tube packaging. Substitution is valid when the following parameters match exactly:

• Slew Rate: 30 V/µs
• Gain Bandwidth Product: 15 MHz
• Current - Input Bias: 5 pA
• Voltage - Input Offset: 2 mV
• Current - Supply: 10 mA
• Current - Output / Channel: 45 mA
• Voltage - Supply Span: 5 V to 16 V
• Operating Temperature: -55°C to 125°C
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Engineering Selection Recommendations

The CA3130AMZ is a direct functional equivalent to the CA3130AM, with all electrical performance parameters and mechanical specifications matching exactly. Selection between these parts is determined by application requirements and regulatory compliance:

CA3130AM is suitable for applications where RoHS non-compliance is acceptable and unlimited moisture sensitivity handling is available. This part is obsolete and inventory is limited to existing stock.

CA3130AMZ is the recommended selection for new designs and ongoing production. This part is active with confirmed availability, offers ROHS3 compliance for applications requiring environmental regulation adherence, and is packaged in tube format suitable for automated assembly processes. The MSL rating of 3 (168 hours) requires standard moisture control during storage and handling but is standard for surface mount components in production environments.

Both parts are classified as REACH Unaffected and carry the same ECCN (EAR99) and HTSUS (8542.33.0001) designations, indicating identical export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can CA3130AMZ be used as a direct replacement for CA3130AM in existing designs?

A: Yes. The CA3130AMZ is electrically and mechanically identical to the CA3130AM. All performance parameters, supply voltage ranges, operating temperature specifications, and package dimensions are equivalent. The primary differences are product status (active versus obsolete) and packaging format (tube versus tape).

Q: What is the significance of the different RoHS compliance status?

A: The CA3130AM is RoHS non-compliant, while the CA3130AMZ is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the CA3130AMZ must be selected. For applications without such requirements, either part is functionally acceptable.

Q: How does the Moisture Sensitivity Level (MSL) difference affect component handling?

A: The CA3130AM has MSL 1 (Unlimited), allowing indefinite storage without moisture control. The CA3130AMZ has MSL 3 (168 hours), requiring that the component be used within 168 hours of package opening under standard moisture control conditions. This is standard for modern surface mount components and does not affect electrical performance or reliability when proper handling procedures are followed.

Q: Are the 8-SOIC packages physically identical?

A: Yes. Both parts use the 8-SOIC package with 0.154" (3.90mm) width. PCB footprints, lead spacing, and mounting requirements are identical. No design modifications are required for package compatibility.

Q: Why is CA3130AM listed as obsolete?

A: The CA3130AM has been discontinued by the manufacturer. The CA3130AMZ represents the current active production equivalent. For new designs and long-term supply assurance, CA3130AMZ should be specified.

Q: Are there any electrical performance differences between these parts?

A: No. Slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, supply voltage range, and operating temperature specifications are identical across both parts.
