Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM5HDW9 with PM5HDW9.0 is based on strict equivalence across all critical parameters that determine functional compatibility:

Electrical Parameters: Both parts operate at identical voltage (2V) and current (30mA) ratings, ensuring direct circuit compatibility without modification to current-limiting resistors or power supply specifications.

Optical Parameters: Lamp color (red), lens transparency (diffused), millicandela rating (25mcd), peak wavelength (625nm), and viewing angle (45°) are identical, guaranteeing equivalent visual performance and brightness characteristics in panel-mounted applications.

Mechanical Parameters: Panel cutout shape (round), cutout dimensions (0.25" / 6.35mm), lens size (5mm T-1 3/4), lens style (round with domed top), and termination style (wire leads 9" / 228.60mm) are identical, confirming direct mechanical interchangeability without panel modification or rewiring.

Environmental Compliance: Both parts carry MSL 1 (Unlimited) rating and EAR99 ECCN classification. PM5HDW9.0 additionally provides RoHS3 compliance, meeting modern regulatory requirements.

The primary distinction is product status: PM5HDW9 is obsolete while PM5HDW9.0 is active, making PM5HDW9.0 the recommended selection for new designs and ongoing procurement.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: PM5HDW9.0 is the direct functional equivalent for applications currently using PM5HDW9. All electrical, optical, and mechanical parameters are identical, enabling drop-in replacement without circuit redesign or panel modification.

For New Designs: PM5HDW9.0 is the appropriate selection, as it maintains active product status with Bivar Inc. and provides RoHS3 compliance, meeting current regulatory and supply chain requirements.

For Inventory Management: PM5HDW9.0 offers superior availability (782 pcs in stock versus 726 pcs for the obsolete PM5HDW9) and ensures long-term supply continuity through its active product designation.

Compliance Considerations: Both parts carry EAR99 ECCN classification and MSL 1 rating. PM5HDW9.0 additionally provides RoHS3 compliance documentation, supporting modern procurement standards and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can PM5HDW9.0 be used as a direct replacement for PM5HDW9 without circuit modification?

A: Yes. PM5HDW9.0 is electrically and mechanically identical to PM5HDW9. Both operate at 2V, 30mA with identical lens specifications and 9-inch wire leads. No resistor, voltage supply, or panel cutout modifications are required.

Q: What is the primary reason to transition from PM5HDW9 to PM5HDW9.0?

A: PM5HDW9 is classified as obsolete, while PM5HDW9.0 is active. This ensures ongoing availability, supply chain stability, and access to current manufacturing documentation and compliance certifications.

Q: Are the optical characteristics identical between these parts?

A: Yes. Both parts provide identical red diffused lens appearance (625nm peak wavelength), 25mcd brightness, 45° viewing angle, and 5mm T-1 3/4 lens form factor. Visual performance in panel-mounted applications is equivalent.

Q: Does PM5HDW9.0 meet modern environmental compliance standards?

A: Yes. PM5HDW9.0 carries RoHS3 compliance certification. Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating and EAR99 ECCN classification.

Q: What is the difference in packaging between PM5HDW9 and PM5HDW9.0?

A: PM5HDW9 packaging is listed as "-" (not specified), while PM5HDW9.0 is supplied in bag packaging. This does not affect component functionality or electrical performance.

Q: Are there any mechanical differences in the lens or panel mounting interface?

A: No. Both parts feature identical round domed-top 5mm lenses, 0.25" (6.35mm) round panel cutout dimensions, and 9-inch wire lead termination. Panel mounting and wiring are identical.
