ELM 3-455 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 3-455 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.455" (11.56mm) length specification. This component is constructed from black PVC material and accommodates standard 5mm LED configurations with three leads. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production environments.

Substitute parts become necessary when the exact length specification is unavailable in inventory, when design tolerance adjustments are required within the mechanical envelope, or when alternative stock levels better support production schedules while maintaining functional compatibility within the ELM 3 series platform.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the ELM 3-455 product family is determined by strict adherence to the following parameters:

Primary Substitution Criteria:

• Manufacturer: Bivar Inc. (same source required)
• Series: ELM 3 (platform compatibility)
• LED Type: T1 3/4 (form factor match)
• Material: Black PVC (physical and electrical properties)
• Lead Configuration: 3LD vertical mounting (mechanical interface)
• RoHS Status: ROHS3 Compliant (regulatory alignment)
• Moisture Sensitivity Level: MSL 1 (handling requirements)

Secondary Substitution Parameter:

• Length: Mechanical dimension within 0.440" to 0.455" range (11.18mm to 11.56mm)

The ELM 3-440 and ELM 3-450 are classified as parametric equivalents because they maintain identical specifications across all primary criteria while varying only in the length dimension within the allowable tolerance band. This length variance accommodates different PCB standoff heights and mechanical clearance requirements without affecting electrical performance or regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

ELM 3-450 Selection Criteria: The ELM 3-450 represents a 0.005" (0.127mm) reduction in length from the primary specification. This substitute maintains full Active product status and ROHS3 compliance. Selection is appropriate when PCB design tolerances accommodate the reduced standoff height or when inventory availability of the ELM 3-450 (8,972 units in stock) provides supply chain advantages over the ELM 3-455 (783 units in stock).

ELM 3-440 Selection Criteria: The ELM 3-440 represents a 0.015" (0.381mm) reduction in length from the primary specification. This substitute maintains full Active product status and ROHS3 compliance. The ELM 3-440 offers the highest inventory availability (22,638 units in stock) and is selected when mechanical clearance requirements or PCB layout constraints necessitate the shorter standoff dimension.

Compliance Assurance: All three parts share identical regulatory classifications (ECCN: EAR99, HTSUS: 3926.90.9985) and moisture sensitivity ratings (MSL 1), ensuring equivalent handling, storage, and export compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can ELM 3-440, ELM 3-450, and ELM 3-455 be used interchangeably in the same application?

A: Interchangeability depends on mechanical tolerance specifications in your PCB design. All three parts share identical electrical and material properties. The length difference (0.015" maximum variance) must be evaluated against your standoff height requirements and component clearance envelope. If your design specifies a fixed standoff height with ±0.015" tolerance, all three parts are interchangeable. If your design requires a specific length, only the designated part number should be used.

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

A: The length variation (0.440", 0.450", 0.455") accommodates different PCB thicknesses and component placement heights in vertical mounting applications. The 0.015" total range allows design flexibility for different board configurations while maintaining the same LED form factor (T1 3/4) and lead configuration (3LD).

Q: Are all three parts ROHS3 compliant?

A: Yes. The ELM 3-455, ELM 3-450, and ELM 3-440 are all ROHS3 compliant. They share identical hazardous substance restriction compliance and can be used in applications requiring ROHS certification.

Q: What is the difference between these parts and the base product number ELM3-4?

A: The base product number ELM3-4 represents the product family platform. The ELM 3-455, ELM 3-450, and ELM 3-440 are specific variants within this family, differentiated by length specification. All variants share the same base platform characteristics.

Q: Do these parts require special moisture handling or storage conditions?

A: No. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity precautions are required. Standard component storage conditions are sufficient.

Q: What packaging format is used for these parts?

A: All three parts are supplied in Bag packaging format, suitable for standard component handling and integration into production workflows.
