Parameter Comparison

Engineering Selection Recommendations

The NCP12510ASN65T1G serves as the active substitute for the obsolete DAP024. Selection of this substitute is based on the following engineering criteria:

Product Status Transition: The DAP024 is obsolete, while the NCP12510ASN65T1G maintains active product status with current manufacturing support and availability.

Regulatory Compliance: Both components satisfy ROHS3 compliance requirements and maintain REACH unaffected status, ensuring compatibility with current regulatory frameworks.

Manufacturer Consistency: Continued use of onsemi components preserves design continuity and leverages established supplier relationships.

Functional Equivalence: Both components operate as offline switch integrated circuits within the Power Management (PMIC) category, supporting offline power conversion applications.

Packaging Consideration: The transition from DIP to surface mount (SOT-23-6 TSOP) packaging requires PCB layout modification and assembly process adjustment.

Frequently Asked Questions (FAQ)

Q: Why is the DAP024 no longer available?

A: The DAP024 has reached obsolete product status. onsemi has discontinued manufacturing and support for this component. The NCP12510ASN65T1G represents the active alternative within the onsemi offline switch product line.

Q: Are the DAP024 and NCP12510ASN65T1G functionally equivalent?

A: Both components function as offline switch integrated circuits within the Power Management (PMIC) category. The DAP024 operates in offline converter topology, while the NCP12510ASN65T1G operates in offline flyback topology. Both topologies serve offline power conversion applications, establishing functional equivalence for this component category.

Q: What are the key differences between these components?

A: Primary differences include product status (obsolete versus active), packaging format (DIP versus SOT-23-6 TSOP surface mount), and specified electrical parameters. The NCP12510ASN65T1G provides documented specifications including supply voltage range (8.9V ~ 35V), switching frequency (65kHz), operating temperature range (-40°C ~ 125°C), and integrated fault protection features.

Q: Does packaging change affect circuit design?

A: Yes. The transition from DIP to surface mount SOT-23-6 TSOP packaging requires PCB layout redesign and assembly process modification. DIP components use through-hole mounting, while TSOP components require surface mount assembly techniques.

Q: Are both components RoHS compliant?

A: Yes. Both the DAP024 and NCP12510ASN65T1G maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements.

Q: What is the moisture sensitivity difference?

A: The DAP024 carries MSL 1 (unlimited moisture sensitivity level), while the NCP12510ASN65T1G carries MSL 3 (168 hours). MSL 3 requires controlled storage conditions and has a 168-hour floor life after moisture exposure. This difference affects component handling, storage, and assembly procedures.

Q: Can I use NCP12510ASN65T1G as a direct pin-for-pin replacement?

A: No. The packaging formats differ fundamentally. DIP and SOT-23-6 TSOP packages have different pin configurations, spacing, and mounting requirements. Circuit board redesign is necessary for component substitution.
