Key Parameters

Substitute Part Grouping Explanation

The Bulgin DX1090/D1 qualifies as a parametric equivalent to the DX1091/D1 based on strict alignment of critical electrical and mechanical parameters. Substitution eligibility is determined by the following key parameters:

Electrical Parameters: Forward voltage (2.2V for both green and red channels) and maximum forward current (30mA for both channels) are identical between the main part and substitute.

Mechanical Parameters: Panel cutout shape (round), cutout dimensions (0.315" / 8.00mm), lens size (5mm, T-1 3/4), and lens style (round with domed top) are identical.

Optical Parameters: Millicandela ratings (5mcd green, 4.5mcd red) match exactly.

Functional Parameters: Termination style (PC pin), ingress protection rating (IP66), and lamp color options (green, red) are identical.

Compliance Parameters: Both parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status.

The primary distinction between these parts is packaging format: DX1091/D1 is supplied in standard packaging, while DX1090/D1 is supplied in bulk packaging. Both parts are active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

Both the DX1091/D1 and DX1090/D1 are suitable for direct substitution in applications requiring LED panel indicators with the specified electrical and mechanical characteristics. Selection between these parts should be based on the following factors:

Packaging Requirements: Standard packaging (DX1091/D1) is appropriate for individual component procurement or small-quantity applications. Bulk packaging (DX1090/D1) is suitable for high-volume manufacturing or assembly operations where bulk quantities reduce per-unit handling costs.

Compliance Assurance: Both parts maintain identical ROHS3 compliance status and REACH unaffected designation, ensuring regulatory compatibility across all markets and applications.

Inventory Availability: Current stock levels are 1111 pieces for DX1091/D1 and 1198 pieces for DX1090/D1, providing adequate supply for both standard and bulk procurement scenarios.

Product Lifecycle Status: Both parts are active products with current manufacturing support, ensuring long-term availability and consistent quality standards.

Frequently Asked Questions (FAQ)

Q: Can DX1090/D1 be used as a direct replacement for DX1091/D1 in existing designs?

A: Yes. The DX1090/D1 is a parametric equivalent with identical electrical specifications (2.2V forward voltage, 30mA maximum current for both green and red channels), mechanical dimensions (8.00mm panel cutout, 5mm lens), optical output (5mcd green, 4.5mcd red), and functional characteristics (PC pin termination, IP66 protection). The only difference is packaging format.

Q: What is the difference between standard and bulk packaging for these parts?

A: DX1091/D1 uses standard packaging suitable for individual component orders and small-quantity applications. DX1090/D1 uses bulk packaging designed for high-volume manufacturing environments where components are ordered in larger quantities. The electrical and mechanical specifications are identical.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both DX1091/D1 and DX1090/D1 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: Do these parts have the same ingress protection rating?

A: Yes. Both parts maintain an IP66 ingress protection rating, providing identical protection against dust and water ingress in panel-mounted applications.

Q: Can I mix DX1091/D1 and DX1090/D1 components in the same assembly?

A: Yes. Since both parts are parametrically identical in all electrical, mechanical, and optical specifications, they can be used interchangeably within the same assembly or production batch without affecting circuit performance or mechanical fit.

Q: What is the moisture sensitivity level for these components?

A: Both parts have a Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating minimal moisture sensitivity and no special storage or handling requirements.
