PM5HT LED Panel Indicator - Equivalent & Substitute Parts

Part Overview

The PM5HT is a panel-mounted LED indicator manufactured by Bivar Inc., classified as a 5mm T-1 3/4 round lens with domed top. This part is designated as Obsolete, making it necessary to identify active equivalent alternatives for continued system support and procurement. The PM5HT operates at 2V with a maximum current of 30mA, producing 40 millicandelas output at a peak wavelength of 625nm with a 35° viewing angle.

Parameter Comparison

Engineering Selection Recommendations

PM5HC is the qualified substitute for PM5HT.

The PM5HC is an Active product, providing continuous manufacturing availability and supply chain stability, whereas the PM5HT is Obsolete. Both parts are manufactured by Bivar Inc. within the PM5 series and meet identical electrical, mechanical, and optical specifications. The PM5HC complies with ROHS3 environmental regulations, representing current manufacturing standards. Selection of PM5HC eliminates obsolescence risk and aligns procurement with active product lines while maintaining full functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can PM5HC directly replace PM5HT in existing assemblies? A: Yes. PM5HC is a direct substitute with identical electrical ratings (2V, 30mA), mechanical form factor (5mm T-1 3/4, 0.25" round cutout), and optical performance (40mcd, 625nm, 35° viewing angle). Both parts mount identically and operate at the same specifications.

Q: What is the difference in lens color between PM5HT (Red) and PM5HC (Colorless)? A: The lens color difference does not affect optical performance. Both lenses are classified as Clear transparency. The red lamp inside the PM5HC produces the same red light output with identical millicandela and wavelength ratings as the PM5HT.

Q: Why is PM5HT listed as Obsolete? A: PM5HT has reached end-of-life status with Bivar Inc. PM5HC remains an Active product and is the designated successor. Organizations using PM5HT should transition to PM5HC for future designs and replenishment orders.

Q: Are there packaging or inventory considerations for substitution? A: PM5HC is supplied in Tray packaging. Verify packaging requirements for your assembly process. Current inventory for PM5HC is 894 pieces in new original stock.

Q: Do regulatory certifications differ between PM5HT and PM5HC? A: Both parts carry EAR99 ECCN and 8541.41.0000 HTSUS classification. PM5HC holds ROHS3 compliance certification, confirming alignment with current environmental and hazardous substance restrictions.
