PM5-KYD Equivalent and Substitute Parts

Part Overview

The PM5-KYD is a panel-mounted LED indicator from Bivar Inc. featuring a yellow diffused lens, 590nm peak wavelength, and 300mcd brightness rating at 2V/20mA operation. This product is classified as Obsolete, making identification of compatible substitute parts essential for ongoing procurement and maintenance applications. The PM5-KYD was designed for applications requiring visible status indication in compact panel-mounted form factors with diffused optical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM5-KYD is governed by the following electrical and mechanical parameters:

Primary Compatibility Criteria:

• Lamp color matching (Yellow 590nm wavelength band)
• Electrical parameters: 2V forward voltage, 20mA maximum current
• Viewing angle: 120° minimum
• Panel mounting compatibility with round cutout geometry

Secondary Compatibility Considerations:

• Panel cutout diameter tolerance (±0.02")
• Lens size and mounting envelope
• Lens style and optical transparency characteristics
• Product availability and manufacturing status

The PM5-KNYD qualifies as a direct substitute based on matching electrical specifications (2V/20mA), wavelength (590nm yellow), and viewing angle (120°). Mechanical differences in panel cutout dimensions (0.41" vs. 0.39") and lens style (domed vs. flat-top) remain within acceptable panel-mounting tolerances for round cutout geometries. The luminous intensity difference (105mcd vs. 300mcd) reflects design trade-offs between availability and performance requirements.

Engineering Selection Recommendations

PM5-KNYD Selection Factors:

The PM5-KNYD is the designated substitute for the obsolete PM5-KYD and is classified as Active product status, ensuring ongoing availability from Bivar Inc. Both parts carry identical electrical ratings (2V/20mA), wavelength specification (590nm), and viewing angle (120°), confirming functional compatibility within the design operating window.

The PM5-KNYD carries RoHS3 Compliant certification, establishing compliance with current environmental regulatory requirements. Both parts share EAR99 export classification and identical HTSUS tariff codes, indicating regulatory parity for procurement purposes.

The mechanical differences between parts—panel cutout dimension variance (0.39" to 0.41") and lens style transition (flat-top to domed)—fall within standard panel-mounting tolerances for round cutout installations. The luminous intensity reduction (300mcd to 105mcd) reflects a design optimization trade-off; applications prioritizing brightness may require secondary optical element evaluation.

Frequently Asked Questions (FAQ)

Q: Can PM5-KNYD directly replace PM5-KYD in existing designs? A: Yes. Both parts share identical electrical parameters (2V/20mA), color wavelength (590nm), and viewing angle (120°). Panel cutout tolerance (0.39" vs 0.41" diameter) accommodates standard round-hole mounting practice. The domed lens style of the PM5-KNYD does not compromise optical compatibility for diffused applications.

Q: What is the brightness difference between PM5-KYD and PM5-KNYD? A: The PM5-KNYD operates at 105mcd compared to the PM5-KYD at 300mcd. This represents a reduction in luminous intensity; applications where brightness is critical should perform photometric evaluation for specific operating conditions.

Q: Why is PM5-KNYD recommended over alternatives? A: PM5-KNYD is the manufacturer-designated substitute and maintains Active product status with current manufacturing support and RoHS3 compliance. It is the only part officially listed in the PM5-KYD substitution field.

Q: Are there mechanical considerations for panel installation? A: The panel cutout diameter tolerance between parts (0.39" to 0.41") is within standard mechanical clearance for round-hole panel mounts. Lens size reduction (9.70mm to 9.10mm) remains accommodated by the larger panel cutout of the substitute. No panel redesign is required for installation.

Q: How do regulatory certifications compare? A: Both parts carry EAR99 export classification, identical HTSUS tariff code (8541.41.0000), and unlimited moisture sensitivity rating (MSL 1). The PM5-KNYD adds RoHS3 Compliant certification, meeting current environmental standards. Export and supply chain compliance are equivalent between parts.
