TC500AIJE Equivalent & Substitute Parts

Part Overview

The TC500AIJE is a 1-channel analog front-end (AFE) integrated circuit manufactured by Microchip Technology, designed for data acquisition applications. This device operates at 16-bit resolution with 10 mW power consumption and is housed in a 16-CERDIP through-hole package. The TC500AIJE is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC500AIJE is determined by the following critical parameters:

• Channel Configuration: Single-channel operation required
• Power Supply Compatibility: Dual supply voltage range ±4.5V ~ 7.5V for both analog and digital domains
• Mounting Technology: Through-hole package format for PCB integration
• Manufacturer Continuity: Microchip Technology product line
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The TC500ACPE qualifies as a direct substitute based on matching channel count, supply voltage specifications, mounting type, and compliance certifications. The primary difference is an increase in resolution from 16-bit to 17-bit, which represents an enhancement rather than a limitation for applications requiring the TC500AIJE.

Parameter Comparison

Engineering Selection Recommendations

The TC500ACPE is the qualified substitute for the obsolete TC500AIJE. Both devices maintain identical power consumption, supply voltage specifications, channel configuration, and compliance certifications. The TC500ACPE offers active product status from Microchip Technology, ensuring continued availability and manufacturing support.

The package designation difference (16-CERDIP versus 16-PDIP) reflects standard industry packaging evolution while maintaining mechanical and electrical compatibility for through-hole PCB mounting. The enhanced 17-bit resolution of the TC500ACPE provides improved measurement precision compared to the original 16-bit specification, with no adverse impact on existing system designs.

Frequently Asked Questions (FAQ)

Q: Can the TC500ACPE directly replace the TC500AIJE in existing designs?

A: Yes. Both devices share identical supply voltage requirements, power consumption, channel count, and through-hole mounting specifications. The 16-DIP and 16-CDIP packages are mechanically compatible for standard PCB footprints designed for 16-pin DIP packages.

Q: What is the significance of the resolution difference between 16-bit and 17-bit?

A: The TC500ACPE provides one additional bit of resolution, resulting in improved measurement precision. This enhancement is backward-compatible with applications designed for the 16-bit TC500AIJE, as the additional resolution does not introduce incompatibilities.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both the TC500AIJE and TC500ACPE maintain identical ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status. No additional qualification is required from a regulatory standpoint.

Q: Why is the TC500AIJE classified as obsolete?

A: The TC500AIJE has reached end-of-life status within Microchip Technology's product portfolio. The TC500ACPE represents the active continuation of this product line with enhanced specifications and ongoing manufacturing support.

Q: Are there packaging considerations for PCB assembly?

A: Both parts use standard 16-pin DIP through-hole packages with 0.300-inch (7.62mm) row spacing. Existing PCB designs and assembly processes require no modification for the substitution.
