Key Parameters

Substitute Part Grouping Explanation

Substitution for the DSP1-DC3V is determined by strict equivalence across the following critical parameters:

• Coil Voltage: Must be 3VDC
• Contact Configuration: Must be DPST-NO/NC (1 Form A, 1 Form B)
• Current Rating: Must be 5 A minimum
• Mounting Type: Must be Through Hole with PC Pin termination
• Switching Specifications: Must support 250VAC, 125VDC maximum switching voltage and 1500VA, 625W maximum load
• Coil Characteristics: Must have 100 mA coil current and 30 Ohms coil resistance
• Operating Temperature: Must support -40°C ~ 65°C range

The DSP1-DC3V-F meets all these criteria and is classified as a direct manufacturer substitute from Panasonic Electric Works.

Parameter Comparison

Engineering Selection Recommendations

The DSP1-DC3V-F is the direct equivalent substitute for the obsolete DSP1-DC3V. Both parts are manufactured by Panasonic Electric Works and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the DSP1-DC3V-F is currently active and available, while the main part is obsolete.

The DSP1-DC3V-F carries RoHS Compliant certification, providing additional regulatory compliance for applications subject to RoHS requirements. Both parts maintain identical approval certifications (cURus, VDE) and moisture sensitivity ratings. For new designs or replacement applications, the DSP1-DC3V-F is the appropriate selection due to its active product status and continued availability.

Frequently Asked Questions (FAQ)

Q: Can DSP1-DC3V-F be used as a direct replacement for DSP1-DC3V?
