Substitute Part Grouping Explanation

The KUP-11DA5-48 has one identified parametric equivalent: KUP-11D55-48. This substitute relationship is established based on strict electrical and mechanical parameter matching within the KUP series of general purpose relays.

The substitution is valid because both parts share identical specifications across all critical parameters:

Coil voltage: 48VDC
Contact form: DPDT (2 Form C)
Contact rating: 10 A
Switching voltage: 240VAC maximum
Coil current: 26.7 mA
Coil resistance: 1.8 kOhms
Termination style: Quick Connect - 0.187" (4.7mm)
Mounting type: Chassis Mount
Operating temperature range: -45°C ~ 70°C
Contact material: Silver Cadmium Oxide (AgCdO)
Coil insulation: Class B
Must operate voltage: 36 VDC
Operate time: 15 ms
Release time: 10 ms
RoHS compliance: ROHS3 Compliant
Moisture sensitivity level: 1 (Unlimited)

The primary difference between these parts is packaging configuration: KUP-11DA5-48 is supplied in standard packaging, while KUP-11D55-48 is supplied in bulk packaging.
