MAX680CPA Equivalent & Substitute Parts

Part Overview

The MAX680CPA is a charge pump switching regulator IC that generates positive and negative dual rail outputs from a single input supply. It produces fixed ±2Vin output at 10mA output current with an 8kHz switching frequency in an 8-DIP through-hole package. The MAX680CPA is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX680CPA is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for:

• Topology (Charge Pump)
• Output configuration (Positive and Negative dual rail)
• Output type (Fixed)
• Number of outputs (2)
• Input voltage range (2V to 6V)
• Output voltage (±2Vin)
• Output current (10mA)
• Switching frequency (8kHz)
• Operating temperature range (0°C ~ 70°C)
• Package and case dimensions (8-DIP, 0.300", 7.62mm)
• Mounting type (Through Hole)

The MAX680CPA+ meets all these criteria and serves as the direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MAX680CPA+ is the direct equivalent for the obsolete MAX680CPA. Both parts share identical electrical specifications and physical packaging. The MAX680CPA+ is currently in active production status, ensuring availability for new designs and production orders.

The MAX680CPA+ provides improved compliance status with ROHS3 certification, whereas the original MAX680CPA is RoHS non-compliant. For applications requiring RoHS compliance, the MAX680CPA+ is the appropriate selection. Both parts maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can MAX680CPA+ directly replace MAX680CPA in existing designs?

A: Yes. The MAX680CPA+ is electrically and mechanically identical to the MAX680CPA across all specified parameters, including input voltage range (2V to 6V), output voltage (±2Vin), output current (10mA), switching frequency (8kHz), operating temperature range (0°C ~ 70°C), and 8-DIP through-hole package dimensions.

Q: What is the primary difference between MAX680CPA and MAX680CPA+?

A: The MAX680CPA+ is the active production equivalent of the obsolete MAX680CPA. The MAX680CPA+ carries ROHS3 compliance certification, while the original MAX680CPA is RoHS non-compliant. Both parts are supplied by Analog Devices Inc./Maxim Integrated.

Q: Are there any package or mounting differences?

A: No. Both parts use identical 8-DIP (0.300", 7.62mm) through-hole packaging and mounting configuration.

Q: Why should I use MAX680CPA+ instead of MAX680CPA?

A: The MAX680CPA is obsolete and no longer in active production. The MAX680CPA+ is the current production equivalent with improved regulatory compliance (ROHS3). For new designs and ongoing production, MAX680CPA+ ensures supply continuity and compliance with modern environmental standards.

Q: Are the electrical characteristics identical?

A: Yes. Both parts maintain identical specifications for input voltage range, output voltage, output current, switching frequency, and operating temperature range.
