ELM 1-480 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 1-480 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a 0.480" (12.19mm) length specification. The part maintains Active product status and is RoHS3 compliant, making it suitable for current electronic assembly requirements. Substitute parts are identified when inventory constraints, lead time considerations, or specific application requirements necessitate alternative components that maintain functional compatibility within the T1 3/4 LED standoff category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 1-480 are qualified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• LED Type: T1 3/4 (all substitutes maintain this specification)
• Color: Black (all substitutes maintain this specification)
• Material Category: Polymer-based (PVC or Nylon acceptable)
• RoHS Compliance: ROHS3 Compliant (all substitutes meet this requirement)
• Mounting Orientation: Vertical standoff configuration

Secondary Consideration:

• Length tolerance: Substitutes may vary within 0.020" (0.51mm) of the primary specification to accommodate different PCB stack-up requirements

The ELM 3-500 and H-278C-2 are identified as parametric equivalents because they maintain the core LED type, color, and compliance requirements while offering alternative length and material options for specific application scenarios.

Parameter Comparison

Engineering Selection Recommendations

ELM 3-500 Selection Criteria: The ELM 3-500 is a direct material equivalent with identical PVC construction and RoHS3 compliance. The 0.020" (0.51mm) length increase accommodates applications requiring slightly greater standoff height. Both parts maintain MSL 1 rating and unlimited moisture tolerance. Selection of ELM 3-500 is appropriate when inventory availability or lead time for the ELM 1-480 is constrained, provided PCB design accommodates the increased length specification.

H-278C-2 Selection Criteria: The H-278C-2 substitutes nylon material for PVC while maintaining T1 3/4 LED compatibility and black color specification. Nylon construction provides enhanced mechanical durability in high-vibration environments. The MSL rating transitions to Not Applicable due to material properties. This substitute is appropriate for applications where material performance characteristics favor nylon over PVC, with length specification matching the ELM 3-500 at 0.500" (12.70mm).

Compliance Verification: All three parts maintain ROHS3 compliance and EAR99 export classification, ensuring regulatory consistency across substitution scenarios.

Frequently Asked Questions (FAQ)

Q: Can ELM 3-500 directly replace ELM 1-480 in existing designs?

A: ELM 3-500 is compatible with ELM 1-480 provided the PCB design accommodates the 0.020" (0.51mm) length increase. Both parts maintain identical LED type (T1 3/4), color (Black), material (PVC), and RoHS3 compliance. Design verification is required to confirm clearance and electrical performance in the specific application.

Q: What is the functional difference between PVC and Nylon material options?

A: Both PVC (ELM 1-480, ELM 3-500) and Nylon (H-278C-2) materials are suitable for T1 3/4 LED standoff applications. Nylon provides enhanced mechanical strength and vibration resistance. PVC offers consistent moisture sensitivity characteristics (MSL 1). Material selection depends on environmental and mechanical requirements of the specific application.

Q: Are all three parts available in the same packaging format?

A: Yes, all three parts are supplied in Bag packaging format, maintaining consistency in handling and assembly processes.

Q: What compliance certifications apply to all substitute options?

A: All three parts are ROHS3 compliant and classified as EAR99 for export purposes. The ELM 3-500 and H-278C-2 are additionally REACH Unaffected. These certifications ensure regulatory consistency across all substitution options.

Q: How does length specification affect component selection?

A: Length specification determines PCB stack-up compatibility and LED positioning height. ELM 1-480 provides 0.480" (12.19mm) height, while both ELM 3-500 and H-278C-2 provide 0.500" (12.70mm) height. Selection requires verification that the application design accommodates the specified length without interference or performance degradation.
