ELM 2-11MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 2-11MM is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.430" (10.92mm) length. This component is constructed from black PVC material and accommodates 3mm LED configurations with 2-lead connections. The part maintains Active product status and is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity tolerance.

Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative components that maintain functional equivalence within the specified parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 2-11MM is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 form factor (non-negotiable)
• Material: Black PVC (color and material consistency)
• LED Configuration: 3mm, 2-lead interface (electrical and mechanical compatibility)
• Mounting Orientation: Vertical (SR VERT designation)
• Regulatory Compliance: ROHS3 Compliant status

Secondary Consideration:

• Length tolerance: Variations within 0.010" (0.25mm) are permissible for mechanical fit in standard PCB mounting holes

The ELM 4-440 qualifies as a parametric equivalent based on matching LED type, material, configuration, orientation, and compliance status. The length differential of 0.010" (0.28mm) falls within acceptable mechanical tolerance for vertical standoff applications.

Parameter Comparison

Engineering Selection Recommendations

ELM 2-11MM Selection Criteria:

• Primary choice when 0.430" (10.92mm) mounting height is specified in design documentation
• Preferred for applications with strict height constraints
• Current inventory: 1058 pieces

ELM 4-440 Selection Criteria:

• Acceptable substitute when 0.010" (0.28mm) additional height is within design tolerance
• Suitable for applications where exact height specification is not critical to function
• Current inventory: 991 pieces

Both parts maintain identical electrical performance, regulatory compliance (ROHS3), and environmental tolerance (MSL 1). Selection between these parts should be based on specific PCB layout requirements and mechanical clearance specifications rather than functional capability.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-440 be used as a direct replacement for ELM 2-11MM?

A: ELM 4-440 is a parametric equivalent with a 0.010" (0.28mm) length increase. Direct substitution is permissible when PCB design accommodates this height differential and no explicit height constraint exists in the design specification.

Q: What is the significance of the length difference between these parts?

A: The 0.010" (0.28mm) difference represents a 0.26% variation in total height. This differential is negligible for most vertical mounting applications but must be verified against specific PCB clearance and component placement requirements.

Q: Are the electrical characteristics identical between ELM 2-11MM and ELM 4-440?

A: Both parts accommodate identical T1 LED types with 3mm, 2-lead configurations. Electrical performance is determined by the LED component itself, not the standoff. The standoff provides mechanical support and positioning only.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both ELM 2-11MM and ELM 4-440 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting identical environmental and regulatory standards.

Q: What packaging format is used for both parts?

A: Both parts are supplied in Bag packaging format suitable for component handling and storage.

Q: Can these parts be used interchangeably in existing designs?

A: Interchangeability depends on design specifications. If the design explicitly requires 0.430" (10.92mm) height, only ELM 2-11MM is appropriate. If height tolerance exists, ELM 4-440 is functionally equivalent.
