Parameter Comparison

Engineering Selection Recommendations

Both the VR05S12 and K7812-500R3 are active products with current manufacturing status and established supply availability. The VR05S12 carries ROHS3 compliance certification, while the K7812-500R3 holds RoHS compliance with additional regulatory approvals including CB, CE, and cURus certifications. The K7812-500R3 includes SCP (Short Circuit Protection) as an integrated feature and carries REACH Unaffected status with MSL 1 (Unlimited) moisture sensitivity rating.

Selection between these parts is determined by specific application requirements regarding regulatory certifications and protection features. The K7812-500R3 provides broader input voltage flexibility with 8V minimum input option in addition to the standard 15V minimum, and offers additional safety certifications suitable for applications requiring CB, CE, or cURus approval pathways. Both parts deliver identical electrical performance in 12V, 500mA output specifications and maintain equivalent thermal and efficiency characteristics across the specified operating range.

Frequently Asked Questions (FAQ)

Q: Can the K7812-500R3 directly replace the VR05S12 in existing circuit board designs?

A: Yes. Both parts share identical output voltage (12V), maximum output current (500mA), operating temperature range (-40°C to 85°C with derating), efficiency (94%), mounting type (through-hole), package format (3-SIP module), and physical dimensions (0.46" L x 0.30" W x 0.40" H). Direct PCB substitution is supported without layout modifications.

Q: What are the input voltage differences between these parts?

A: The VR05S12 operates with input voltage range of 15V to 36V. The K7812-500R3 offers extended input flexibility with options for 8V to 24V or 15V to 36V configurations. For applications requiring 15V to 36V input operation, both parts are functionally equivalent.

Q: Are there regulatory compliance differences between the VR05S12 and K7812-500R3?

A: The VR05S12 carries ROHS3 compliance. The K7812-500R3 holds RoHS compliance with additional certifications including CB, CE, and cURus approvals. Applications requiring specific regulatory certifications should reference the appropriate part based on compliance pathway requirements.

Q: Does the K7812-500R3 include additional protection features?

A: The K7812-500R3 integrates SCP (Short Circuit Protection) as a standard feature. The VR05S12 specifications do not list this protection feature. Applications requiring integrated short circuit protection benefit from K7812-500R3 selection.

Q: Are the physical package dimensions identical?

A: Yes. Both the VR05S12 and K7812-500R3 are packaged in 3-SIP module format with identical dimensions of 0.46" L x 0.30" W x 0.40" H (11.6mm x 7.6mm x 10.2mm), supporting direct mechanical interchangeability in through-hole PCB applications.

Q: What is the moisture sensitivity rating difference?

A: The VR05S12 lists MSL as Not Applicable. The K7812-500R3 carries MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage and handling.
