The Hirose HRFC-P8-H3(61) is a simplex fiber optic plug from the HRFC series, designed for single-fiber terminations in controlled indoor environments. It accepts a 3.0mm cable diameter and supports both 9.5µm single-mode and 50µm multi-mode fiber cores with a 125µm cladding diameter. The Advanced PC Polished finish and blue boot with integral strain relief make it a field-terminable choice for patch panels or equipment cabinets where the operating temperature stays between -25°C and 70°C.
This part carries a Last Buy lifecycle status. That means Hirose has announced end-of-production — the window to secure inventory is closing. There is no official successor or direct replacement on record for the HRFC-P8-H3(61). If this connector is on your BOM, the procurement action is to source remaining stock through the independent channel now, before availability tightens further.
Key fit parameters at a glance
The 3.0mm cable diameter acceptance is the first check — the boot and internal strain relief are sized for that O.D., so a 2.0mm or 4.0mm cable will not seat properly. The 9.5µm/50µm core compatibility means this plug works with both single-mode and multi-mode fiber, but the ferrule and polish (Advanced PC) are matched to the fiber type you terminate — confirm the ferrule bore matches your fiber before committing.
