Bulgin DX1091/YL LED Panel Indicator Yellow 2.1V Equivalent & Substitute Parts

Part Overview

The Bulgin DX1091/YL is an active yellow LED panel indicator designed for 2.1V operation at 30mA maximum current. This component features a 5mm T-1 3/4 round domed lens with IP66 ingress protection and PC pin termination, suitable for panel-mount applications requiring a 0.315" (8.00mm) round cutout. The part is ROHS3 compliant and REACH unaffected, with MSL rating of 1 (unlimited moisture sensitivity).

Substitute parts are necessary when primary inventory is unavailable, when sourcing from alternative Bulgin series within the same product line, or when maintaining component standardization across manufacturing batches while preserving identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

All substitute parts listed—DX1090/YL, DX1092/YL, and DX1093/YL—are parametric equivalents within the Bulgin DX series yellow LED panel indicator family. Substitution is valid based on the following criteria:

Electrical Parameters (Identical):

  • Forward voltage: 2.1V (Typical)
  • Maximum current: 30mA
  • Millicandela rating: 20mcd

Mechanical Parameters (Identical):

  • Lens size: 5mm, T-1 3/4
  • Lens style: Round with Domed Top
  • Panel cutout shape: Round
  • Panel cutout dimensions: 0.315" (8.00mm)
  • Termination style: PC Pin

Environmental & Compliance Parameters (Identical):

  • Ingress protection: IP66
  • RoHS status: ROHS3 Compliant
  • REACH status: REACH Unaffected
  • MSL rating: 1 (Unlimited)
  • Packaging: Bulk

These parts differ only in their base series designation (DX1090, DX1091, DX1092, DX1093) and current inventory levels. All are active products from Bulgin with identical functional and physical specifications.

Engineering Selection Recommendations

All four parts—DX1091/YL, DX1090/YL, DX1092/YL, and DX1093/YL—are functionally and mechanically interchangeable for applications requiring a yellow LED panel indicator with 2.1V forward voltage and 30mA maximum current in a 5mm T-1 3/4 package with 0.315" (8.00mm) round panel cutout.

Selection among these parts should be based on:

Product Status: All parts maintain active status with Bulgin, ensuring continued availability and support.

Compliance Certifications: All parts carry identical ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and consumer applications.

Inventory Availability: DX1092/YL offers the highest current stock (1393 Pcs), followed by DX1093/YL (920 Pcs), DX1090/YL (873 Pcs), and DX1091/YL (780 Pcs). Selection may prioritize availability for high-volume procurement.

Moisture Sensitivity: All parts share MSL rating 1 (unlimited), eliminating moisture-related handling constraints across all substitute options.

Frequently Asked Questions (FAQ)

Q: Can DX1090/YL, DX1092/YL, and DX1093/YL be used interchangeably with DX1091/YL in existing designs?

A: Yes. All four parts are parametric equivalents with identical electrical ratings (2.1V forward voltage, 30mA maximum current), mechanical dimensions (5mm T-1 3/4 lens, 0.315" round panel cutout), and termination style (PC Pin). Direct substitution is valid without circuit modification.

Q: Are there differences in optical performance between these parts?

A: No. All parts share identical millicandela rating (20mcd) and lens configuration (round with domed top). Optical output and viewing characteristics are equivalent.

Q: What is the significance of the different series numbers (DX1090, DX1091, DX1092, DX1093)?

A: Series designation indicates different product lines within Bulgin's yellow LED panel indicator family. Despite different series numbers, these parts maintain identical electrical, mechanical, and environmental specifications, making them true parametric equivalents.

Q: Do all substitute parts meet the same environmental protection standards?

A: Yes. All parts carry IP66 ingress protection rating, ensuring equivalent sealing performance against dust and water ingress across all substitute options.

Q: Are there any compliance or regulatory differences between these parts?

A: No. All parts are ROHS3 compliant and REACH unaffected with identical MSL rating of 1 (unlimited). Regulatory status and handling requirements are identical across all four parts.

Q: Which part should be selected for new designs?

A: Any of the four parts is suitable for new designs. Selection may be based on current inventory availability, supplier preference, or existing component standardization within your organization. All parts carry active product status with Bulgin.
