Same outline. Murata figures are the catalogue values for this body. HVC ratings are continuous values in air. Confirm the medium and the duty in the RFQ.

Why buyers arrive with a MHR0614SA number

The usual case is not a purchase order. It is a repair, a drawing carried over from an older machine, or a design inherited from a supplier that no longer supports it. The number is the only firm fact available, and the question behind it is simply whether the part can still be obtained at the printed outline.

That is a different question from price. Murata builds MHR0614SA in nine resistance steps; anything between the steps, anything above 1.2 W, or anything above 6 kV in air has no catalogue answer at all, and that is where a cut-to-outline plate replaces the original rather than competing with it.

Reading the MHR0614SA voltage figure

Two columns sit behind the headline number: 6 kV for single use and 12 kV for molded use. The gap is the potting, not the resistor. A substitute quoted at the molded figure without the molding is not the same part, so state the medium and the duty in the enquiry and the quotation will match it.

MHR0614SA ordering codes

El código es MHR0614SA plus a three digit resistance code, a tolerance letter and a two digit individual specification: 70 for single use, 20 for molded use. Standard resistance steps are 10, 15, 20, 25, 30, 40, 50, 68 and 80; the three digit code carries two significant figures and the number of zeros that follow.

Tolerance letters: D ±0.5%, F ±1%, G ±2%, J ±5%, K ±10%, M ±20%. Replace F with the tolerance you need, and 70 con 20 for the molded specification. HVC builds any value in the range to the same outline.

MHR0614SA replacement FAQ

Do I need to have bought the MHR0614SA before?

No. Most enquiries arrive with a part number and no purchase history - a repair, a legacy drawing, or a design inherited from another team. Send the number and the quantity; HVC quotes a substitute against the printed outline rather than asking for an order history.

Is the MHR0614SA body still available?

HVC supplies the HVRGHP9.15 plate cut to 15.1 mm, 9 mm high, with the lead pitch set to 12.7 mm. This size is held as a catalogue outline.

What does the voltage figure actually mean?

Murata lists two columns: 6 kV single use and 12 kV molded use. The higher number depends on the part being potted. HVC quotes a continuous working voltage in air, so compare air with air and ask for the medium on any substitute you are offered.

Can HVC supply values outside the 1 to 2000 MΩ range?

Yes. Murata builds nine resistance steps; HVC builds any value in the range, which is the usual reason a buyer with a MHR0614SA drawing cannot simply re-order the original.
