MPC3HT LED Panel Indicator - Equivalent & Substitute Parts

Part Overview

The MPC3HT is a panel-mount LED indicator manufactured by Bivar Inc., featuring a red clear lens with 50mcd brightness rating at 625nm wavelength. The product is classified as obsolete, making it necessary to identify functionally equivalent active alternatives for continued system designs and maintenance applications. The MPC3HT operates at 2V with a maximum current of 30mA and accommodates standard 0.24" (6.10mm) round panel cutouts with a 3mm T-1 lens form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution criteria for the MPC3HT are based on electrical and mechanical parameters that ensure form-fit-function compatibility:

Critical Matching Parameters:

• Voltage: 2V
• Current: 30mA maximum
• Panel Cutout Dimensions: 0.24" (6.10mm) round
• Lens Size: 3mm, T-1
• Wavelength - Peak: 625nm (red spectrum)
• Lamp Color: Red
• Lens Color: Red

Allowable Variation Parameters:

• Lens Transparency: Clear to Diffused (affects light distribution, not electrical compatibility)
• Millicandela Rating: 50mcd to 30mcd (both provide visible indication within the red LED category)
• Viewing Angle: 20° to 35° (impacts visibility cone, not electrical or mechanical fit)

The MPC3HD qualifies as a functional substitute based on identical electrical specifications (2V, 30mA), matching mechanical form factor (6.10mm round cutout, 3mm T-1 lens), and equivalent wavelength (625nm red). The MPC3HD differs only in optical characteristics (diffused lens, 30mcd brightness, 35° viewing angle) while maintaining active product status and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The MPC3HD is a qualified substitute for the obsolete MPC3HT. Selection is based on product status transition from obsolete to active classification, with confirmed RoHS3 compliance for the substitute part. Both components share identical electrical ratings (2V, 30mA) and mechanical compatibility (0.24" round panel cutout, 3mm T-1 form factor).

The MPC3HD optical differences—diffused lens transparency and 35° viewing angle versus the MPC3HT's 20° viewing angle—result in broader light distribution. The reduced millicandela rating (30mcd vs. 50mcd) reflects the diffusion effect while maintaining indicator visibility. These optical characteristics are within acceptable variation for panel-mount indicator applications where the primary requirement is status indication within the red spectrum at the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can the MPC3HD directly replace the MPC3HT in existing designs? The MPC3HD is electrically and mechanically compatible with the MPC3HT. Both operate at 2V with 30mA maximum current and share identical 0.24" (6.10mm) round panel cutout dimensions and 3mm T-1 lens form factors. Optical differences (clear vs. diffused lens, 20° vs. 35° viewing angle) affect light distribution and brightness perception but do not impact electrical circuit compatibility.

Q: How does the diffused lens affect the MPC3HD performance compared to the clear lens MPC3HT? The diffused lens of the MPC3HD spreads light over a wider viewing angle (35° vs. 20°), resulting in lower peak brightness (30mcd vs. 50mcd) but broader visibility across a wider range of angles. The choice between clear and diffused lenses depends on application visibility requirements and viewing geometry rather than electrical specifications.

Q: Are both parts RoHS compliant? The MPC3HD is certified RoHS3 compliant. RoHS status for the obsolete MPC3HT is not specified in available documentation.

Q: What is the moisture sensitivity implication for these components? Both the MPC3HT and MPC3HD carry Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: Does the wavelength differ between the two parts? No. Both the MPC3HT and MPC3HD operate at 625nm peak wavelength, confirming identical red spectrum performance.
