Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT214110 are identified based on strict parametric equivalence within the TE Connectivity Potter & Brumfield Relays product portfolio. The substitution logic is based on the following critical parameters that must remain identical:

• Coil voltage specification (110VDC)
• Contact form configuration (SPDT / 1 Form C)
• Contact current rating (12 A)
• Maximum switching voltage (400VAC)
• Coil current draw (3.8 mA)
• Coil resistance (28.8 kOhms)
• Mounting technology (Through Hole)
• Termination style (PC Pin)
• Operating temperature range (-40°C ~ 85°C)
• Must operate and release voltage thresholds
• Switching time specifications (operate and release times)
• Contact material composition (Silver Nickel)
• Coil type (Non Latching)
• Environmental sealing (Sealed - Flux Protection)
• Coil insulation class (Class F)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The RT114110 satisfies all substitution requirements and belongs to the same RT1 and SCHRACK series family.

Parameter Comparison

Engineering Selection Recommendations

Both the RT214110 and RT114110 are active production parts manufactured by TE Connectivity Potter & Brumfield Relays and maintain full compliance with ROHS3 and REACH regulatory requirements. Both parts carry identical ECCN (EAR99) and HTSUS classifications, confirming their equivalence for export and procurement purposes.

The RT114110 substitute part demonstrates complete parametric alignment with the RT214110 across all electrical, mechanical, and environmental specifications. Both relays are sealed with flux protection, feature Class F coil insulation, and operate within the identical temperature range of -40°C to 85°C. The switching characteristics, including operate time (8 ms) and release time (6 ms), are identical, ensuring equivalent performance in timing-critical applications.

Selection between these parts may be based on inventory availability and lead time considerations. The RT114110 currently maintains higher stock levels (2299 pieces) compared to the RT214110 (1118 pieces), which may influence procurement decisions for high-volume applications or urgent requirements.
