LPC660IM Equivalent & Substitute Parts

Part Overview

The LPC660IM is a CMOS operational amplifier manufactured by Texas Instruments, featuring four independent amplifier circuits in a 14-SOIC surface mount package. The device provides push-pull, rail-to-rail output capability with low input bias current and is designed for general-purpose analog signal processing applications.

The LPC660IM carries an Obsolete product status. Locating equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this component.

Substitute Part Grouping Explanation

Substitute parts for the LPC660IM are identified based on strict electrical and mechanical parameter compatibility. The primary substitution criterion is the LPC660IM/NOPB variant, which shares identical electrical specifications and package configuration.

The substitution logic is based on the following key parameters:

• Amplifier Type: CMOS topology
• Circuit Count: Four independent amplifier circuits
• Output Configuration: Push-Pull, Rail-to-Rail output
• Slew Rate: 0.11 V/µs
• Gain Bandwidth Product: 350 kHz
• Input Bias Current: 0.002 pA
• Input Offset Voltage: 1 mV
• Supply Current: 160 µA (total for four channels)
• Output Current per Channel: 40 mA
• Supply Voltage Range: 4.75 V to 15.5 V
• Operating Temperature: -40°C to 85°C
• Package: 14-SOIC surface mount

Parts meeting all these electrical and mechanical specifications are classified as direct substitutes. The LPC660IM/NOPB is the primary equivalent, differing only in packaging format (Tube) and product status (Last Time Buy).

Parameter Comparison

Engineering Selection Recommendations

The LPC660IM/NOPB is the direct equivalent substitute for the LPC660IM. Both parts are manufactured by Texas Instruments and provide identical electrical performance and mechanical compatibility. The primary distinction is product status and regulatory compliance.

The LPC660IM carries Obsolete status, indicating end-of-life designation. The LPC660IM/NOPB is designated Last Time Buy, representing the final procurement window before complete discontinuation. The LPC660IM/NOPB additionally carries ROHS3 compliance certification, whereas the original LPC660IM is RoHS non-compliant. Both parts maintain MSL Level 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status.

For new designs or ongoing production requiring compliance with current regulatory standards, the LPC660IM/NOPB is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, either part provides functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the LPC660IM/NOPB be used as a direct replacement for the LPC660IM?

A: Yes. The LPC660IM/NOPB provides identical electrical specifications and package configuration. Both parts are 14-SOIC surface mount devices with four CMOS amplifier circuits, identical slew rate (0.11 V/µs), gain bandwidth product (350 kHz), and supply voltage range (4.75 V to 15.5 V). The primary difference is packaging format and product status.

Q: What is the difference between LPC660IM and LPC660IM/NOPB?

A: The LPC660IM/NOPB is supplied in Tube packaging, whereas the original LPC660IM packaging format is not specified. The LPC660IM/NOPB carries ROHS3 compliance certification and Last Time Buy status, while the LPC660IM is RoHS non-compliant and Obsolete. Electrical performance is identical.

Q: Are there any mechanical compatibility issues when substituting LPC660IM/NOPB for LPC660IM?

A: No. Both parts use the 14-SOIC (0.154", 3.90mm Width) surface mount package. Pin configuration, footprint, and mounting requirements are identical. PCB layout and assembly processes require no modification.

Q: What is the significance of the Last Time Buy status for LPC660IM/NOPB?

A: Last Time Buy designation indicates this is the final production run before complete discontinuation. Inventory availability is limited. For applications requiring long-term supply assurance, alternative amplifier solutions should be evaluated.

Q: Does the ROHS3 compliance of LPC660IM/NOPB affect electrical performance?

A: No. RoHS compliance is a regulatory and material composition specification. Electrical performance, operating characteristics, and functional behavior remain identical between RoHS-compliant and non-compliant variants of the same base part number.

Q: What is MSL Level 1 (Unlimited) moisture sensitivity?

A: MSL Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Standard warehouse conditions are acceptable. No baking or desiccant storage is required prior to assembly.
