Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VIPER53DIP-E are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

Electrical Specifications:

• Topology: Flyback
• Output Isolation: Isolated
• Voltage - Breakdown: 620V
• Voltage - Supply (Vcc/Vdd): 8.4V ~ 19V
• Voltage - Start Up: 11.5V
• Frequency - Switching: Up to 300kHz
• Power (Watts): 50W
• Fault Protection: Current Limiting, Over Load, Over Temperature, Short Circuit
• Control Features: EN, Frequency Control, Soft Start
• Operating Temperature: -40°C ~ 150°C (TC)

Mechanical Specifications:

• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Supplier Device Package: 8-DIP

Compliance & Status:

• Product Status: Active
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The VIPER53EDIP-E is a direct parametric equivalent to the VIPER53DIP-E. Both components are manufactured by STMicroelectronics and share identical electrical specifications, mechanical packaging, and compliance certifications. Selection between these parts is based on availability and supply chain requirements rather than functional differences.

Both parts maintain Active product status, ensuring long-term availability and manufacturer support. Both are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and commercial applications. The identical 8-DIP through-hole package ensures pin-for-pin compatibility and direct board-level substitution without design modification.

The VIPER53EDIP-E currently maintains higher inventory availability (90,100 pieces) compared to the VIPER53DIP-E (1,826 pieces), making it the preferred selection for high-volume production or extended lead-time mitigation.

Frequently Asked Questions (FAQ)

Q: Are VIPER53DIP-E and VIPER53EDIP-E pin-for-pin compatible?

A: Yes. Both components use identical 8-DIP (0.300", 7.62mm) through-hole packaging with matching pin configurations. Direct board-level substitution is supported without design changes.

Q: What are the critical parameters that define substitutability for the VIPER53DIP-E?

A: Substitutability is determined by matching: flyback topology, 620V breakdown voltage, 8.4V–19V supply voltage range, 11.5V startup voltage, 300kHz maximum switching frequency, 50W power rating, identical fault protection features (current limiting, overload, overtemperature, short circuit), control features (EN, frequency control, soft start), -40°C to 150°C operating temperature range, and 8-DIP through-hole package.

Q: Can I use VIPER53EDIP-E as a direct replacement in existing designs?

A: Yes. The VIPER53EDIP-E meets all electrical and mechanical specifications of the VIPER53DIP-E. No circuit modifications or board redesign is required for substitution.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both VIPER53DIP-E and VIPER53EDIP-E are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the difference between VIPER53DIP-E and VIPER53EDIP-E?

A: Both parts are functionally and electrically identical. The designation difference reflects manufacturing batch or packaging tube variations. All electrical specifications, performance characteristics, and compliance certifications are equivalent.

Q: Which part should I select for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supply chain lead times. The VIPER53EDIP-E currently has higher stock levels.
