TC962IJA Equivalent & Substitute Parts

Part Overview

The TC962IJA is a charge pump switching regulator IC manufactured by Microchip Technology, designed for power management applications requiring positive or negative fixed output voltage generation. This device operates as a ratiometric regulator with a single output capable of delivering 80mA across an input voltage range of 3V to 18V. The TC962IJA is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC962IJA is determined by equivalence across the following critical parameters:

• Topology & Function: Charge pump switching regulator with ratiometric output configuration
• Output Capability: Positive or negative fixed output voltage generation with single output
• Electrical Performance: 80mA output current, 3V to 18V input voltage range, 12kHz to 24kHz switching frequency
• Package Compatibility: Through-hole mounting in 8-pin DIP configuration
• Compliance: ROHS3 compliance and MSL Level 1 rating

The TC962EPA qualifies as a direct substitute based on identical electrical specifications and compatible package footprint, with the distinction of active product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The TC962EPA is the manufacturer-recommended substitute for the obsolete TC962IJA. Both devices share identical electrical specifications and are manufactured by Microchip Technology under the same base product number TC962. The TC962EPA maintains ROHS3 compliance and MSL Level 1 rating, ensuring regulatory and environmental compatibility with the original design.

The TC962EPA offers an extended operating temperature range of -40°C to 85°C compared to the TC962IJA range of -25°C to 85°C, providing additional thermal margin for applications operating at lower ambient temperatures. Package footprints are compatible for through-hole mounting, with both devices specified in 8-pin DIP configurations at 0.300" (7.62mm) spacing.

Frequently Asked Questions (FAQ)

Q: Can TC962EPA directly replace TC962IJA in existing designs?

A: Yes. Both devices are charge pump switching regulators with identical electrical specifications: 80mA output current, 3V to 18V input voltage range, 12kHz to 24kHz switching frequency, and positive or negative fixed output voltage configuration. Through-hole package footprints are compatible for PCB mounting.

Q: What is the difference between 8-CDIP and 8-DIP packaging?

A: Both designations refer to 8-pin dual inline packages with 0.300" (7.62mm) spacing suitable for through-hole mounting. The packages are mechanically and electrically compatible for board-level substitution.

Q: Why is TC962IJA listed as obsolete?

A: Product obsolescence indicates the device is no longer in active production. The TC962EPA, as the active equivalent, is the recommended source for new component procurement and design implementations.

Q: Does the extended temperature range of TC962EPA affect compatibility?

A: No. The TC962EPA operating range of -40°C to 85°C encompasses the TC962IJA range of -25°C to 85°C. Applications designed for the original temperature specification remain fully compatible with the substitute device.

Q: Are both devices RoHS compliant?

A: Yes. Both TC962IJA and TC962EPA are ROHS3 compliant with MSL Level 1 rating, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
