LED Panel Indicator PM3HD Equivalent & Substitute Parts

Part Overview

The PM3HD is an active LED panel indicator manufactured by Bivar Inc., designed for panel-mount applications with wire termination. This red diffused lens indicator operates at 2V with a maximum current rating of 30mA and delivers 30mcd luminous intensity at a 625nm peak wavelength. The component features a 3mm T-1 round domed lens with a 40° viewing angle and accommodates a 0.16" (4.06mm) round panel cutout. As an active product with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), the PM3HD remains in production. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design alternatives where electrical and mechanical parameters align within acceptable tolerances.

Substitute Part Grouping Explanation

Substitute parts for the PM3HD are identified based on strict alignment of electrical and mechanical parameters that determine functional compatibility in panel-mount LED indicator applications. The substitution logic is based on the following criteria:

Electrical Compatibility: Voltage rating (2V) and current rating must support the design circuit without exceeding maximum ratings. The PM3HD operates at 2V with a 30mA maximum current specification.

Optical Compatibility: Lamp color (red), lens color (red), and lens transparency (diffused) must match to maintain consistent visual indication and light distribution characteristics.

Mechanical Compatibility: Panel cutout shape (round), panel cutout dimensions (0.16" / 4.06mm), lens size (3mm T-1), and lens style (round with domed top) must align to ensure proper physical fit and mounting without modification.

Regulatory Compliance: RoHS3 compliance and MSL 1 rating ensure the substitute part meets environmental and handling requirements equivalent to the main part.

Luminous Intensity and Wavelength: While these parameters may vary within acceptable ranges for red LED indicators, they are documented for reference in application-specific brightness and color matching requirements.

Engineering Selection Recommendations

Primary Part (PM3HD): The PM3HD remains the specified component for applications requiring 30mcd luminous intensity at 625nm peak wavelength with a 40° viewing angle. This part is active in production, ROHS3 compliant, and carries unlimited moisture sensitivity rating (MSL 1), suitable for standard industrial and commercial panel-mount indicator applications.

Substitute Part (5580101001F): The Dialight 5580101001F is electrically and mechanically compatible for panel-mount applications where the following conditions are met: (1) the circuit design accommodates a maximum current rating of 20mA, (2) the application accepts reduced luminous intensity of 10mcd compared to the 30mcd specification of the PM3HD, and (3) the wavelength shift from 625nm to 650nm is acceptable for the intended visual indication. This substitute is also ROHS3 compliant with MSL 1 rating and is active in production.

Compliance and Regulatory Status: Both parts meet ROHS3 environmental compliance requirements and carry identical MSL 1 ratings, indicating equivalent handling and storage requirements. Both are classified under HTSUS code 8541.41.0000 and ECCN EAR99, supporting equivalent regulatory treatment in procurement and export contexts.

Packaging Consideration: The PM3HD is supplied in bag packaging, while the 5580101001F is supplied in bulk packaging. This difference affects inventory management, component handling procedures, and procurement quantities but does not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 5580101001F substitute for the PM3HD in all applications?

A: The 5580101001F is mechanically and electrically compatible for panel-mount applications. However, substitution is conditional on circuit design and application requirements. The substitute part has a lower maximum current rating (20mA vs. 30mA) and lower luminous intensity (10mcd vs. 30mcd). Applications requiring the full 30mcd brightness or operating at currents above 20mA must use the PM3HD.

Q: What is the significance of the wavelength difference between 625nm and 650nm?

A: Both wavelengths fall within the red spectrum visible to the human eye. The PM3HD operates at 625nm (pure red), while the 5580101001F operates at 650nm (red-orange shift). For applications where precise color matching or spectral characteristics are critical, the wavelength difference must be evaluated against application requirements. For general red indicator applications, both wavelengths are functionally equivalent.

Q: Does the lower millicandela rating of the 5580101001F affect compatibility?

A: The 5580101001F delivers 10mcd compared to the PM3HD's 30mcd. This represents a three-fold reduction in luminous intensity. Substitution is acceptable only in applications where this reduced brightness meets visibility requirements. Applications requiring high-brightness indication or operation in high-ambient-light environments should retain the PM3HD.

Q: Are there differences in viewing angle between these parts?

A: The PM3HD specifies a 40° viewing angle. The 5580101001F viewing angle is not specified in the provided data. Both parts use identical 3mm T-1 round domed lens styles, suggesting similar optical characteristics, but the unspecified viewing angle for the substitute part should be confirmed with the manufacturer if viewing angle is a critical application parameter.

Q: What is the impact of different packaging (bag vs. bulk)?

A: Packaging differences affect procurement, handling, and inventory management but do not impact electrical or mechanical performance. Bag packaging (PM3HD) typically supports smaller order quantities and individual component handling. Bulk packaging (5580101001F) is suited for high-volume production environments. Component selection should consider manufacturing process requirements and inventory practices.

Q: Are both parts suitable for long-term storage?

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating they can be stored indefinitely without special moisture-control measures. Both are ROHS3 compliant and suitable for standard industrial storage conditions without degradation of electrical or mechanical properties.

Q: Can the PM3HD and 5580101001F be used interchangeably in existing designs?

A: Interchangeability depends on design specifications. If the design specifies 30mcd brightness and 40° viewing angle, the PM3HD is required. If the design can accommodate 10mcd brightness and the viewing angle specification is not critical, the 5580101001F is compatible. Circuit current ratings must not exceed 20mA for the substitute part. Physical panel cutout dimensions are identical (0.16" / 4.06mm round), supporting direct mechanical substitution.
