ELM 1-245 T1 3/4 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 1-245 is a T1 3/4 LED standoff manufactured by Bivar Inc., constructed from black PVC material with a length of 0.245" (6.22mm). This component is classified as an active product and is RoHS3 compliant. LED standoffs serve as mechanical mounting and alignment components for T1 3/4 LED packages in vertical orientation applications. Substitute parts become necessary when specific length tolerances, material properties, or lead configuration requirements differ from the primary specification, or when inventory availability necessitates alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 1-245 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 3/4 (all substitutes maintain this specification)
• Color: Black (all substitutes maintain this specification)
• Orientation: Vertical (all substitutes maintain this specification)
• RoHS Status: ROHS3 Compliant (all substitutes maintain this specification)
• Moisture Sensitivity Level: 1 (Unlimited) (all substitutes maintain this specification)

Variable Parameters Allowing Substitution:

• Length: 0.245" (6.22mm) baseline; substitutes range from 0.235" (5.97mm) to 0.250" (6.35mm)
• Material: PVC or Nylon
• Series: ELM 1 or ELM 3
• Lead Configuration: 2-lead or 3-lead designs

The five identified substitute parts maintain all mandatory compatibility parameters while offering variations in physical length and material composition. These variations accommodate different PCB mounting depths and mechanical tolerance requirements while preserving the core LED standoff functionality.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory and supply chain continuity. Selection among substitutes is determined by specific application requirements:

For PVC Material Requirement (ELM 1 Series):

• ELM 1-250: 0.250" (6.35mm) length for applications requiring maximum standoff height
• ELM 1-6MM: 0.240" (6.10mm) length for applications requiring intermediate standoff height
• ELM 1-245: Original specification at 0.245" (6.22mm) length

For PVC Material with Multi-Lead Configuration (ELM 3 Series):

• ELM 3-250: 0.250" (6.35mm) length with 3-lead design
• ELM 3-235: 0.235" (5.97mm) length with 3-lead design

For Nylon Material Alternative:

• 909-235 BK: 0.235" (5.97mm) length in nylon construction, offering alternative material properties while maintaining T1 3/4 LED compatibility

All substitutes carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can ELM 1-250 be used as a direct replacement for ELM 1-245?

A: ELM 1-250 is a parametric equivalent with identical material (PVC), color (black), LED type (T1 3/4), and compliance specifications. The length difference is 0.005" (0.13mm), which may be acceptable depending on PCB mounting depth tolerance. Verify mechanical clearance in your specific application before substitution.

Q: What is the difference between ELM 1 and ELM 3 series standoffs?

A: The ELM 1 series features 2-lead configuration, while the ELM 3 series features 3-lead configuration. Both series maintain identical LED type (T1 3/4), color (black), and compliance status. Series selection depends on your PCB design and lead count requirements.

Q: Can 909-235 BK replace ELM 1-245?

A: 909-235 BK maintains T1 3/4 LED compatibility, black color, and identical compliance specifications. The material differs (nylon versus PVC) and length is 0.010" (0.25mm) shorter. Material substitution is acceptable if your application does not require specific PVC properties. Verify mechanical fit for the reduced length.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 Compliant status, matching the original ELM 1-245 specification.

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

A: Moisture Sensitivity Level 1 indicates no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly processes.

Q: Which substitute offers the closest dimensional match to ELM 1-245?

A: ELM 1-6MM at 0.240" (6.10mm) provides the closest length match, differing by only 0.005" (0.12mm) from the original 0.245" (6.22mm) specification while maintaining identical PVC material and ELM 1 series classification.
