Substitute Part Grouping Explanation

Substitution of the 7102-05-1101 is based on electrical and mechanical parameter equivalence. The primary substitute, Coto Technology 8L02-05-01, maintains functional compatibility through the following critical parameters:

• Identical coil voltage specification (5 VDC)
• Identical contact form configuration (DPST-NO, 2 Form A)
• Identical contact current rating (500 mA)
• Identical maximum switching voltage (200 VAC, 200 VDC)
• Identical coil type (Non Latching)
• Identical diode feature
• Identical termination style (PC Pin)
• Identical mounting type (Through Hole)
• Identical operating temperature range (-20°C ~ 85°C)
• Equivalent regulatory compliance (RoHS and REACH)

The 8L02-05-01 represents an active product from the same manufacturer, providing continuity for applications currently utilizing the obsolete 7102-05-1101.
