TC962MJA Equivalent & Substitute Parts

Part Overview

The TC962MJA 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 TC962MJA is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC962MJA is determined by equivalence across the following critical parameters:

• Base product number (TC962 series)
• Topology (Charge Pump)
• Output configuration (Positive or Negative)
• Input voltage range (3V to 18V)
• Output current capability (80mA)
• Switching frequency (12kHz ~ 24kHz)
• Number of outputs (1)
• Output type (Fixed)
• RoHS compliance status

The TC962EPA qualifies as a manufacturer-recommended substitute based on identical electrical performance specifications and base product lineage. The primary distinction lies in packaging format and operating temperature range, which are application-dependent considerations rather than functional limitations.

Parameter Comparison

Engineering Selection Recommendations

The TC962EPA is the active manufacturer-recommended substitute for the obsolete TC962MJA. Both devices share identical electrical specifications and are manufactured by Microchip Technology under the TC962 base product number. Both maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Selection between these parts depends on application-specific requirements:

The TC962MJA supports an extended operating temperature range of -55°C to 125°C, suitable for industrial and military-grade applications requiring broader thermal performance. The TC962EPA operates within -40°C to 85°C, appropriate for commercial and consumer applications.

Package format differs between the two devices. The TC962MJA uses 8-CDIP (ceramic dual in-line package), while the TC962EPA uses 8-DIP (plastic dual in-line package). Both maintain identical 0.300" (7.62mm) pitch and through-hole mounting compatibility, allowing direct PCB footprint substitution with appropriate component placement verification.

For new designs and production continuity, the TC962EPA is the appropriate selection due to active product status and equivalent electrical performance. For applications requiring extended temperature operation below -40°C or above 85°C, the TC962MJA may be sourced from existing inventory if available.

Frequently Asked Questions (FAQ)

Q: Can TC962EPA directly replace TC962MJA in existing designs?

A: Yes, the TC962EPA provides electrical equivalence across all functional parameters including input voltage range, output voltage configuration, output current, and switching frequency. PCB layout compatibility is maintained through identical 0.300" pitch and through-hole mounting. Package material difference (ceramic versus plastic) does not affect electrical performance for standard commercial and industrial applications.

Q: What is the primary difference between TC962MJA and TC962EPA?

A: The TC962MJA is obsolete with extended temperature operation (-55°C to 125°C), while TC962EPA is active with commercial temperature range (-40°C to 85°C). Package format also differs: TC962MJA uses ceramic dual in-line (CDIP), TC962EPA uses plastic dual in-line (DIP). Electrical specifications remain identical.

Q: Are both parts RoHS compliant?

A: Yes, both TC962MJA and TC962EPA are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Q: Which part should be selected for new production?

A: The TC962EPA should be selected for new designs and ongoing production due to active product status and equivalent electrical performance. The TC962MJA is obsolete and should only be used when existing inventory is available and application requirements do not conflict with its extended temperature specification.

Q: Does package format affect circuit performance?

A: Package format (ceramic versus plastic) does not affect electrical performance. Both 8-CDIP and 8-DIP packages maintain identical pin pitch and through-hole mounting compatibility. Selection depends on application thermal requirements and PCB assembly process compatibility.
