Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SD25490P is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Transistor type must be NPN
• Voltage - Collector Emitter Breakdown (Max) must be 80 V or greater
• Current - Collector (Ic) (Max) must be 3 A or greater
• Power - Max must be 2 W or greater
• Operating temperature range must support 150°C maximum junction temperature

Mechanical Equivalence Criteria:

• Mounting type must be Through Hole
• Package / Case must be TO-220-3 or compatible TO-220 variant

The TIP31BG manufactured by onsemi meets all specified electrical and mechanical substitution criteria. Both devices share identical maximum ratings for collector-emitter breakdown voltage (80 V), maximum collector current (3 A), and maximum power dissipation (2 W). Both are packaged in TO-220-3 through-hole configurations suitable for direct pin-compatible replacement.

Parameter Comparison

Engineering Selection Recommendations

The TIP31BG is a direct electrical and mechanical substitute for the 2SD25490P. Both devices are rated identically for maximum collector-emitter breakdown voltage (80 V), maximum collector current (3 A), and maximum power dissipation (2 W). Pin configuration and through-hole TO-220-3 packaging enable direct replacement without circuit board modification.

The TIP31BG offers the advantage of active product status, ensuring continued availability and supply chain support. The device is ROHS3 compliant, meeting current environmental and regulatory requirements. The 2SD25490P is classified as obsolete and non-compliant with RoHS standards.

For new designs or production requiring long-term component availability and regulatory compliance, the TIP31BG is the appropriate selection. For legacy system maintenance where original component specifications must be preserved, the TIP31BG provides functional equivalence with enhanced compliance status.

Frequently Asked Questions (FAQ)

Q: Can the TIP31BG replace the 2SD25490P in existing circuits?

A: Yes. Both devices share identical maximum electrical ratings (80 V, 3 A, 2 W) and are packaged in pin-compatible TO-220-3 through-hole configurations. Direct substitution is possible without circuit modification.

Q: What are the key differences between these devices?

A: The primary differences are product status and regulatory compliance. The 2SD25490P is obsolete and RoHS non-compliant. The TIP31BG is an active product with ROHS3 compliance. Electrical and mechanical specifications are equivalent.

Q: Are there any performance differences I should consider?

A: Both devices meet the same maximum electrical specifications. Differences in DC current gain (hFE), saturation voltage, and transition frequency exist but do not affect substitution eligibility when maximum ratings are the controlling design constraint.

Q: Is the TO-220-3 package identical between both parts?

A: Both devices use TO-220-3 through-hole packaging. Pin assignments are compatible, enabling direct board-level replacement without rework.

Q: Why is the 2SD25490P listed as obsolete?

A: The 2SD25490P is no longer in active production by Panasonic Electronic Components. The TIP31BG serves as the active equivalent in the market.

Q: Does RoHS compliance affect circuit performance?

A: RoHS compliance relates to material composition and environmental standards, not electrical performance. Both devices function identically within their rated specifications.
