• Inductance value: 27 mH @ 10 kHz
• Number of lines: 2-line configuration
• Current rating: 800mA minimum
• DC resistance: 500mOhm typical
• Mounting type: Through hole
• Physical dimensions: 22.50mm L x 21.50mm W x 14.60mm H maximum
• Package configuration: Horizontal, 4 pin

The RN114-0.8-02-27M meets all substitution criteria as a direct equivalent from the same manufacturer, Schaffner EMC Inc., within the RN series family. This substitute maintains identical electrical performance specifications and mechanical form factor compatibility.

Parameter Comparison

Engineering Selection Recommendations

The RN114-0.8-02-27M is the direct substitute for the obsolete RN114-0.8-02. Both components are manufactured by Schaffner EMC Inc. and share identical electrical specifications and mechanical dimensions. The substitute part offers the following advantages:

• Active product status with current manufacturing support
• Enhanced regulatory compliance (ROHS3 vs. RoHS Compliant)
• Additional approval certification (ENEC added to UR and VDE)
• Higher AC voltage rating (300V vs. 250V)
• Improved inventory availability (30,955 pcs vs. 946 pcs)

The RN114-0.8-02-27M operates within a reduced temperature range (-40°C to 100°C versus -40°C to 125°C). Applications requiring operation above 100°C must evaluate this specification change against system requirements.

Frequently Asked Questions (FAQ)
