Substitute Part Grouping Explanation

Substitution of the DSP1-DC12V is determined by strict equivalence across the following critical parameters:

• Coil voltage: 12VDC
• Contact configuration: DPST-NO/NC (1 Form A, 1 Form B)
• Current rating: 5 A minimum
• Switching voltage capability: 250VAC, 125VDC maximum
• Mounting type: Through Hole
• Termination style: PC Pin
• Coil resistance: 480 Ohms
• Coil current: 25 mA
• Operating temperature range: -40°C ~ 65°C minimum
• Contact material: Silver Tin Oxide (AgSnO)
• Seal rating: Sealed - Fully

The DSP1-DC12V-F is identified as a direct substitute based on identical electrical specifications, contact configuration, and mechanical compatibility. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The DSP1-DC12V-F is the direct functional equivalent of the DSP1-DC12V. Both relays are manufactured by Panasonic Electric Works and share identical electrical and mechanical specifications. The DSP1-DC12V-F is currently in active production status, whereas the DSP1-DC12V is obsolete.
