Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PMR4HDW6.0 is determined by strict alignment with the following critical parameters:

Mechanical Compatibility:

• Panel cutout shape and dimensions (0.22" x 0.14" / 5.59mm x 3.56mm rectangle)
• Lens size (4.00mm x 2.10mm)
• Lens style (rectangle with flat top)
• Termination style (wire leads - 6" length)

Optical Compatibility:

• Lamp color (red)
• Lens color (red)
• Lens transparency (diffused)
• Viewing angle (120°)

Electrical Compatibility:

• Maximum current rating (30mA)
• Forward voltage operating range (2V nominal)

Environmental & Regulatory:

• Moisture sensitivity level (MSL 1 - Unlimited)
• Series designation (PMR4)

Substitute parts must maintain identical mechanical and optical specifications. Electrical parameters may vary within acceptable operating ranges provided the substitute part operates within the same current and voltage envelope as the original design.

Parameter Comparison

Engineering Selection Recommendations

PMR4RDW6.0 as Primary Substitute:

The PMR4RDW6.0 is the designated substitute for the obsolete PMR4HDW6.0. Both components share identical mechanical specifications, panel cutout dimensions, lens geometry, and termination configuration, ensuring direct physical compatibility in existing panel designs.

Product Status Consideration:

The PMR4HDW6.0 is obsolete with no ongoing manufacturing. The PMR4RDW6.0 maintains active production status, ensuring long-term supply availability and design continuity for new production runs or field replacements.

Compliance & Certification:

The PMR4RDW6.0 carries ROHS3 compliance certification, meeting current environmental and regulatory requirements. Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating, indicating no special handling requirements during storage or assembly.

Electrical Parameter Variance:

The forward voltage differs by 0.1V (2V vs. 2.1V). This variance falls within acceptable operating tolerances for standard LED indicator circuits. Circuit designs accommodating the original 2V specification will operate the PMR4RDW6.0 within rated parameters.

Optical Performance Differences:

The PMR4RDW6.0 exhibits reduced luminous intensity (0.4mcd vs. 8mcd) and a longer peak wavelength (700nm vs. 625nm). These differences result in a dimmer, more orange-tinted appearance compared to the original part. Applications requiring specific brightness or color matching should evaluate visual performance in the target environment.

Frequently Asked Questions (FAQ)

Q: Can the PMR4RDW6.0 directly replace the PMR4HDW6.0 in existing designs?

A: Yes, from a mechanical and electrical standpoint. Both components feature identical panel cutout dimensions (0.22" x 0.14"), lens size (4.00mm x 2.10mm), wire lead length (6"), and maximum current rating (30mA). The forward voltage difference (0.1V) is within standard operating tolerance for LED indicator circuits. However, the reduced brightness (0.4mcd vs. 8mcd) and wavelength shift (700nm vs. 625nm) will produce a visually dimmer, more orange-tinted indicator. Evaluate visual performance requirements before implementation.

Q: What are the key mechanical compatibility factors?

A: Panel cutout shape and dimensions must match exactly: 0.22" x 0.14" (5.59mm x 3.56mm) rectangle. Lens size (4.00mm x 2.10mm) and lens style (rectangle with flat top) must be identical. Termination must be wire leads with 6" length. All substitute parts in the PMR4 series maintain these specifications.

Q: Are there packaging differences between the main part and substitute?

A: The PMR4HDW6.0 is supplied without specified packaging designation. The PMR4RDW6.0 is supplied in bag packaging. This difference does not affect component functionality or electrical performance, only handling and storage logistics.

Q: What is the significance of the wavelength difference (625nm vs. 700nm)?

A: The 625nm wavelength (PMR4HDW6.0) produces a pure red appearance. The 700nm wavelength (PMR4RDW6.0) produces a more orange-red appearance. In applications where color perception is critical for operator recognition or system status indication, this difference may be significant. Standard indicator applications typically tolerate this variation.

Q: Why is the millicandela rating significantly lower on the substitute part?

A: The PMR4RDW6.0 (0.4mcd) produces substantially less light output than the PMR4HDW6.0 (8mcd). This difference reflects different LED die specifications within the same mechanical package. Applications relying on high brightness for visibility in bright ambient conditions may require circuit design adjustments or alternative component selection.

Q: Are both parts RoHS compliant?

A: The PMR4RDW6.0 carries explicit ROHS3 compliance certification. The PMR4HDW6.0 RoHS status is not specified in available documentation. For applications requiring RoHS compliance verification, the PMR4RDW6.0 provides documented compliance.

Q: What is the moisture sensitivity level, and does it affect handling?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity. Standard handling procedures apply; no special dry storage, baking, or moisture barrier packaging is required.
