ELM 4-365 Equivalent & Substitute Parts

Part Overview

The ELM 4-365 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.365" (9.27mm) length. The component features a black PVC construction and accommodates 2-lead configurations. This part is currently active in production and maintains full ROHS3 compliance with MSL 1 rating, indicating unlimited moisture sensitivity tolerance.

Substitute parts are identified when equivalent functional performance can be achieved through alternative designs within the same product family, differing primarily in series designation, material composition, or dimensional specifications that remain within acceptable tolerance ranges for the application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-365 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 (all substitutes maintain this specification)
• Configuration: 2-Lead Vertical Mount (all substitutes maintain this specification)
• Color: Black (all substitutes maintain this specification)
• RoHS Status: ROHS3 Compliant (all substitutes maintain this specification)
• Moisture Sensitivity Level: 1 (all substitutes maintain this specification)
• Product Status: Active (all substitutes maintain this specification)

Secondary Variation Parameters:

• Length: 0.365" (9.27mm) primary specification; 0.350" (8.89mm) and 0.380" (9.65mm) represent minor dimensional variations
• Material: PVC (primary) versus Nylon (alternative material option)
• Series: ELM 4 (primary) versus ELM 2 (alternative series) versus H-201C (alternative series)

All identified substitutes maintain functional equivalence for T1 LED standoff applications while accommodating dimensional and material variations within the Bivar Inc. product portfolio.

Parameter Comparison

Engineering Selection Recommendations

ELM 2-365: This part represents the closest functional equivalent to the ELM 4-365. Both components share identical length (0.365" / 9.27mm), material (PVC), and all critical compliance parameters. The primary distinction is series designation (ELM 2 versus ELM 4). This substitute is suitable for direct replacement in applications where the ELM 4 series is not specifically mandated. Inventory availability is significantly higher (16125 units versus 1100 units).

ELM 2-350: This part maintains material consistency (PVC) and all compliance requirements but features a reduced length of 0.350" (8.89mm) compared to the 0.365" specification. This 0.015" (0.38mm) dimensional reduction is applicable only in applications where standoff height tolerance permits the shorter dimension. All regulatory and environmental compliance parameters remain equivalent.

H-201C: This part introduces material variation (Nylon versus PVC) while maintaining all other critical parameters including T1 LED type, 2-lead configuration, and compliance certifications. The length specification is 0.380" (9.65mm), representing a 0.015" (0.38mm) increase over the primary part. Material selection between PVC and Nylon should be determined by application-specific environmental and mechanical requirements. This option provides the highest inventory availability (63104 units).

All substitute parts maintain Active product status and full ROHS3 compliance with MSL 1 rating, ensuring regulatory equivalence for component selection purposes.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-365 be used as a direct replacement for ELM 4-365?

A: Yes. The ELM 2-365 maintains identical length (0.365" / 9.27mm), material (PVC), LED type (T1), configuration (2-lead vertical mount), and all compliance specifications (ROHS3, MSL 1). The series designation difference does not affect functional performance in standard LED standoff applications.

Q: What is the significance of the length difference between ELM 4-365 (0.365") and ELM 2-350 (0.350")?

A: The ELM 2-350 provides a 0.015" (0.38mm) shorter standoff height. This dimensional reduction is acceptable only in applications where PCB clearance and component spacing tolerances accommodate the reduced height. Verify application-specific height requirements before substitution.

Q: Why would H-201C be selected over ELM 2-365 despite the material difference?

A: H-201C offers superior inventory availability (63104 units versus 16125 units for ELM 2-365) and maintains all critical compliance parameters. The material change from PVC to Nylon may be advantageous in applications requiring enhanced mechanical strength or specific environmental resistance. Material selection should align with application-specific performance requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitutes (ELM 2-350, ELM 2-365, and H-201C) maintain ROHS3 compliance equivalent to the primary part ELM 4-365. Regulatory compliance is maintained across all options.

Q: What is the Moisture Sensitivity Level (MSL) for all parts in this comparison?

A: All parts, including the primary ELM 4-365 and all substitutes, maintain MSL 1 (Unlimited) rating. This indicates no moisture sensitivity restrictions for storage, handling, or operational conditions.

Q: Does packaging differ between the main part and substitutes?

A: No. All parts are supplied in Bag packaging format, ensuring consistent handling and storage requirements across the product family.

Q: Can dimensional variations between substitutes affect PCB layout?

A: Yes. Length variations of 0.015" (0.38mm) between options (ELM 2-350 at 0.350", ELM 4-365 at 0.365", and H-201C at 0.380") may impact vertical clearance and component spacing. Verify application-specific dimensional requirements before substitution.
