ELM 4-900 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-900 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.900" (22.86mm) length. This component is constructed from black PVC material and accommodates 3MM LED packages with 2-lead configurations. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production environments. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative components that maintain functional and mechanical compatibility within the allowed parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-900 is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• LED Type: T1
• Material: Black PVC
• LED Package Size: 3MM
• Lead Configuration: 2LD
• Mounting Orientation: Vertical
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Length tolerance: Components within the mechanical envelope of 0.900" to 0.910" (22.86mm to 23.11mm) are classified as parametric equivalents. This minor dimensional variation does not affect functional performance in standard vertical mounting applications where the standoff height accommodates typical PCB-to-component clearance requirements.

The ELM 5-23MM meets all critical matching parameters and falls within the allowable length tolerance, qualifying it as a parametric equivalent substitute.

Engineering Selection Recommendations

ELM 5-23MM as Substitute for ELM 4-900:

The ELM 5-23MM is classified as a parametric equivalent and direct substitute for the ELM 4-900. Both components share identical manufacturer origin (Bivar Inc.), LED type (T1), material composition (Black PVC), package size (3MM), lead configuration (2LD), and compliance certifications (ROHS3). The length differential of 0.010" (0.25mm) represents a 1.1% variation and remains within acceptable mechanical tolerances for vertical LED standoff applications.

Both parts maintain Active product status, ensuring continued availability and manufacturing support. Identical RoHS3 compliance and MSL ratings confirm regulatory and environmental compatibility. The ELM 5-23MM currently maintains higher inventory availability (7087 Pcs) compared to the ELM 4-900 (875 Pcs), making it suitable for applications where supply continuity is a consideration.

Selection between these parts should be based on specific PCB layout requirements and clearance specifications. The 0.010" length difference must be evaluated against the mechanical constraints of the target application.

Frequently Asked Questions (FAQ)

Q: Can the ELM 5-23MM be used as a direct replacement for the ELM 4-900 in all applications?

A: The ELM 5-23MM is a parametric equivalent substitute. Both components share identical electrical and material specifications. The 0.010" (0.25mm) length difference must be evaluated against your specific PCB clearance and component spacing requirements. If the application tolerates this dimensional variation, direct substitution is valid.

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

A: The ELM 4-900 measures 0.900" (22.86mm) while the ELM 5-23MM measures 0.910" (23.11mm). This 0.010" variation is typical in LED standoff manufacturing and falls within standard mechanical tolerances. For vertical mounting applications, this difference affects the final height of the LED above the PCB by approximately 0.25mm.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the ELM 4-900 and ELM 5-23MM are ROHS3 compliant, confirming they meet current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What does MSL 1 (Unlimited) mean for these components?

A: Moisture Sensitivity Level 1 (Unlimited) indicates these components have no moisture sensitivity restrictions. They do not require special moisture-controlled storage, handling, or baking procedures prior to assembly. Standard storage conditions are acceptable.

Q: Are there any differences in packaging between these parts?

A: No. Both the ELM 4-900 and ELM 5-23MM are supplied in Bag packaging, ensuring consistent handling and storage requirements.

Q: Which part should I select if inventory is a concern?

A: The ELM 5-23MM currently maintains significantly higher inventory (7087 Pcs) compared to the ELM 4-900 (875 Pcs). If supply continuity is a priority and the 0.010" length difference is acceptable for your application, the ELM 5-23MM is the preferred selection.

Q: Do these parts have different ECCN or HTSUS classifications?

A: No. Both parts share identical ECCN (EAR99) and HTSUS (3926.90.9985) classifications, confirming they have identical export control and tariff treatment.
