PM3HDW6 LED Panel Indicator - Equivalent & Substitute Parts

Part Overview

The PM3HDW6 is a 3mm red LED panel indicator assembly manufactured by Bivar Inc., designed for panel mount applications with diffused lens and 6-inch wire leads. This component is classified as Obsolete product status. The PM3HDW6 operates at 2V forward voltage with a maximum current rating of 30mA, delivering 30 millicandela brightness at a 625nm peak wavelength with a 40° viewing angle.

Due to its obsolete status, identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production, repair, and maintenance applications. The substitute part PM3HDW6.0 provides functional equivalence with modified electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM3HDW6 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Requirements:

• Lens size: 3mm, T-1 form factor
• Panel cutout shape: Round configuration
• Panel cutout dimensions: 0.16" (4.06mm)
• Lens style: Round with domed top
• Termination: Wire leads with 6-inch length

Optical Compatibility Requirements:

• Lens color: Red
• Lens transparency: Diffused
• Millicandela rating: 30mcd
• Peak wavelength: 625nm
• Viewing angle: 40°

Electrical Compatibility Requirements:

• Forward voltage: 2V
• Maximum current rating: Must support circuit design requirements

The substitute part PM3HDW6.0 maintains full mechanical and optical equivalence. The electrical specification differs in maximum current rating (20mA versus 30mA), which represents a reduced current capacity. This substitution is valid only when circuit design current requirements do not exceed 20mA.

Engineering Selection Recommendations

PM3HDW6.0 Substitution Criteria:

The PM3HDW6.0 is the direct substitute for the obsolete PM3HDW6 based on the following engineering factors:

1. Product Status: PM3HDW6.0 maintains Active product status, ensuring ongoing availability and manufacturing support, whereas PM3HDW6 is classified as Obsolete.

2. Mechanical Compatibility: All mechanical parameters are identical, including lens size (3mm, T-1), panel cutout dimensions (0.16" / 4.06mm round), lens style (round with domed top), and wire lead termination (6 inches).

3. Optical Equivalence: Optical specifications are fully matched: red lens color, diffused transparency, 30mcd brightness, 625nm peak wavelength, and 40° viewing angle.

4. Electrical Consideration: Forward voltage remains at 2V. Maximum current rating is reduced from 30mA to 20mA. Substitution is valid only when circuit design current requirements do not exceed 20mA.

5. Compliance Certification: PM3HDW6.0 carries ROHS3 compliance certification, meeting current environmental and regulatory standards.

6. Environmental Rating: Both parts maintain MSL 1 (Unlimited) moisture sensitivity level, indicating equivalent environmental performance.

Frequently Asked Questions (FAQ)

Q: Can PM3HDW6.0 be used as a direct replacement for PM3HDW6 in all applications?

A: PM3HDW6.0 provides mechanical and optical equivalence. Substitution is valid only when the circuit design current requirement does not exceed 20mA. The original PM3HDW6 supports up to 30mA; PM3HDW6.0 supports up to 20mA maximum current.

Q: What are the mechanical compatibility requirements for substitution?

A: The substitute part must maintain identical lens size (3mm, T-1), panel cutout shape (round), panel cutout dimensions (0.16" / 4.06mm), lens style (round with domed top), and termination style (wire leads, 6 inches). PM3HDW6.0 meets all these requirements.

Q: Are the optical specifications identical between PM3HDW6 and PM3HDW6.0?

A: Yes. Both parts deliver 30mcd brightness at 625nm peak wavelength with 40° viewing angle, red lens color, and diffused lens transparency.

Q: What is the significance of the Active product status for PM3HDW6.0?

A: Active product status indicates that PM3HDW6.0 is currently manufactured and supported by Bivar Inc., ensuring component availability for new production and ongoing supply. The original PM3HDW6 is Obsolete and no longer manufactured.

Q: Does PM3HDW6.0 meet current environmental compliance standards?

A: Yes. PM3HDW6.0 carries ROHS3 compliance certification. Both parts maintain MSL 1 (Unlimited) moisture sensitivity level.

Q: What packaging differences exist between the main part and substitute?

A: PM3HDW6 packaging is listed as "-" (not specified). PM3HDW6.0 is supplied in Bag packaging.

Q: Are there any electrical parameter differences that affect circuit design?

A: Forward voltage is identical at 2V. Maximum current rating differs: PM3HDW6 supports 30mA; PM3HDW6.0 supports 20mA. Circuit designs must operate within the 20mA maximum for PM3HDW6.0 substitution.
