ELM 4-890 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-890 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.890" (22.61mm) 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, 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 4-890 is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• LED Type: T1
• Material: Black PVC
• LED Configuration: 3MM 2-Lead
• Mounting Style: Vertical
• Manufacturer: Bivar Inc.
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Length tolerance: Components within the mechanical envelope of LED standoff applications

The substitute part ELM 5-23MM meets all critical matching parameters. The length variation from 0.890" (22.61mm) to 0.910" (23.11mm) represents a 0.020" (0.50mm) difference, which falls within acceptable mechanical tolerances for vertical LED standoff applications where the standoff height accommodates standard PCB-to-LED spacing requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: ELM 4-890 The ELM 4-890 is the specified component and maintains Active product status with full ROHS3 compliance. Current inventory of 1025 pieces supports immediate procurement requirements.

Substitute Selection: ELM 5-23MM The ELM 5-23MM serves as a functional equivalent when ELM 4-890 availability is constrained. Both components share identical electrical and material specifications, with mechanical compatibility confirmed through the 0.020" length differential. The substitute maintains Active product status and ROHS3 compliance. Higher inventory availability (7087 pieces) supports extended lead time mitigation. Selection between these parts is based solely on availability, lead time, and mechanical clearance verification within the specific application assembly.

Frequently Asked Questions (FAQ)

Q: What determines if ELM 5-23MM can replace ELM 4-890? A: Substitution is valid when the application accommodates the 0.020" (0.50mm) length increase from 22.61mm to 23.11mm. Both components are identical in LED type (T1), material (Black PVC), configuration (3MM 2-Lead), and compliance status (ROHS3). The length difference must be evaluated against PCB-to-LED spacing and mechanical clearance requirements in the specific assembly.

Q: Are there electrical differences between ELM 4-890 and ELM 5-23MM? A: No. Both components are passive mechanical standoffs for T1 LED mounting. Electrical performance is determined by the LED component itself, not the standoff. The standoff provides only mechanical positioning and structural support.

Q: Do both parts have the same moisture sensitivity rating? A: Yes. Both ELM 4-890 and ELM 5-23MM carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions during storage, transport, or assembly.

Q: Can ELM 5-23MM be used in applications originally designed for ELM 4-890? A: Substitution is permissible only when the mechanical envelope of the assembly accommodates the additional 0.020" standoff height. Design verification is required to confirm that the increased length does not create interference with adjacent components or violate mechanical clearance specifications.

Q: What is the packaging format for both parts? A: Both ELM 4-890 and ELM 5-23MM are supplied in Bag packaging, suitable for bulk component handling and automated assembly processes.

Q: Are both parts compliant with current regulatory requirements? A: Yes. Both components are ROHS3 compliant and carry EAR99 export classification with HTSUS code 3926.90.9985, meeting current environmental and trade compliance standards.
