• Resistance value: 12.4 kOhms
• Tolerance: ±0.1%
• Power rating: 0.1W (1/10W)
• Composition: Thin Film
• Package: 0805 (2012 Metric)
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Height seated maximum: 0.026" (0.65mm)
• Terminations: 2
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Parts meeting all these parameters are classified as direct equivalents and may be substituted without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

The substitute part RN73C2A12K4BTDF is a direct electrical and mechanical equivalent to the 1676173-5. Both components are manufactured by TE Connectivity within the RN73 Holsworthy series and maintain Active product status. Both parts are ROHS3 Compliant and carry identical electrical specifications including resistance, tolerance, power rating, temperature coefficient, and operating temperature range.

The primary distinction between these parts is packaging format. The 1676173-5 is supplied in bulk packaging, while the RN73C2A12K4BTDF is supplied in Tape & Reel (TR) format.
