PM5HTW12.0 Equivalent & Substitute Parts

Part Overview

The PM5HTW12.0 is a panel mount LED indicator manufactured by Bivar Inc., designed for applications requiring a red light signal with wire lead termination. This component features a 5mm T-1 3/4 lens with a domed top, rated for 2V operation at 30mA maximum current, and delivers 40 millicandela output at a 625nm peak wavelength with a 35° viewing angle.

The PM5HTW12.0 is classified as obsolete. Identification of equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this indicator is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM5HTW12.0 is based on electrical and mechanical compatibility within the PM5 series. The substitute part must satisfy the following criteria:

Electrical Parameters (Critical):

• Voltage rating: 2V
• Maximum current: 30mA
• Peak wavelength: 625nm (red spectrum)
• Millicandela output: 40mcd

Mechanical Parameters (Critical):

• Lens size: 5mm, T-1 3/4
• Panel cutout shape and dimensions: Round, 0.25" (6.35mm)
• Lens style: Round with domed top
• Termination: Wire leads with 12" (304.80mm) length

Optical Parameters (Critical):

• Viewing angle: 35°
• Lens transparency: Clear

The PM5HCW12.0 meets all specified electrical, mechanical, and optical parameters and is therefore classified as a direct substitute for the PM5HTW12.0.

Parameter Comparison

Engineering Selection Recommendations

The PM5HCW12.0 is the direct substitute for the obsolete PM5HTW12.0. Both components share identical electrical ratings, mechanical dimensions, optical specifications, and termination configuration.

Status Advantage: The PM5HCW12.0 carries Active product status, ensuring continued availability and supply chain support, whereas the PM5HTW12.0 is classified as Obsolete.

Compliance Advantage: The PM5HCW12.0 is certified ROHS3 Compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Lens Color Difference: The PM5HTW12.0 features a red lens color, while the PM5HCW12.0 features a colorless lens. Both maintain clear lens transparency. This difference does not affect electrical or optical performance parameters, as the red lamp color and 625nm peak wavelength remain constant in both variants.

Inventory Availability: The PM5HCW12.0 maintains 787 pieces in new original stock, providing immediate availability for component procurement.

Frequently Asked Questions (FAQ)

Q: Can the PM5HCW12.0 replace the PM5HTW12.0 in existing designs?

A: Yes. The PM5HCW12.0 is electrically and mechanically identical to the PM5HTW12.0. Both components operate at 2V, 30mA maximum, deliver 40mcd output at 625nm wavelength, feature identical 5mm T-1 3/4 lens geometry, and use 12-inch wire lead termination. Panel cutout dimensions are identical at 0.25" (6.35mm).

Q: What is the difference between the red lens color of the PM5HTW12.0 and the colorless lens of the PM5HCW12.0?

A: The PM5HTW12.0 has a red-tinted lens, while the PM5HCW12.0 has a colorless (transparent) lens. Both maintain clear transparency. The red lamp color and 625nm peak wavelength are identical in both parts, so the visual output remains the same. The lens color difference is a cosmetic variation that does not affect electrical performance or light output characteristics.

Q: Why is the PM5HTW12.0 classified as obsolete?

A: The PM5HTW12.0 has reached end-of-life status in the manufacturer's product portfolio. The PM5HCW12.0 is the active replacement within the PM5 series, offering the same functional specifications with current production support and regulatory compliance.

Q: Does the PM5HCW12.0 meet current environmental standards?

A: Yes. The PM5HCW12.0 is ROHS3 Compliant, meeting current environmental and regulatory requirements for electronic components. The PM5HTW12.0 compliance status is not specified in available documentation.

Q: Are the wire lead lengths identical between both parts?

A: Yes. Both the PM5HTW12.0 and PM5HCW12.0 feature 12-inch (304.80mm) wire lead termination.

Q: What is the packaging difference between these parts?

A: The PM5HTW12.0 packaging is listed as standard, while the PM5HCW12.0 is supplied in Bag packaging. This difference does not affect component functionality or performance.
