ELM 3-310 LED Standoff Equivalent and Substitute Parts

Part Overview

The ELM 3-310 is a T1 3/4 LED standoff manufactured by Bivar Inc., constructed from black PVC material with a height specification of 0.310" (7.87mm). This component is classified as an active product with full ROHS3 compliance and unlimited moisture sensitivity tolerance (MSL 1). Alternative models become necessary when dimensional constraints require different standoff heights, allowing design flexibility across PCB assembly specifications while maintaining the same functional LED mount characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 3-310 are determined by equivalence in the following critical parameters: LED type (T1 3/4), material composition (black PVC), and functional mounting capability. The two substitute parts differ from the main part and each other only in length specification. Both substitute parts maintain identical LED type, material, color, and manufacturer origin, with variation limited to the standoff height dimension.

Key Parameters for Substitution:

• LED Type: T1 3/4
• Material: PVC
• Color: Black
• Manufacturer: Bivar Inc.
• Length: 0.300" (7.62mm) for substitutes versus 0.310" (7.87mm) for main part

Parameter Comparison

Engineering Selection Recommendations

All three parts—ELM 3-310, ELM 3-300, and ELM 1-300—carry active product status and full ROHS3 compliance certification, indicating continued manufacturing support and environmental regulatory alignment. Both substitute parts are suitable alternatives from a compliance perspective. Selection between the main part and substitutes depends solely on the required standoff height specification for the specific PCB assembly design. The ELM 3-300 remains within the same ELM 3 series, while the ELM 1-300 belongs to the ELM 1 series; all maintain identical material, LED type, and functional characteristics.

Frequently Asked Questions (FAQ)

Q: What defines compatibility between the ELM 3-310 and its substitutes? A: Compatibility is determined by three core parameters: T1 3/4 LED type, black PVC material composition, and identical mounting functionality across all parts. Differences are limited to standoff height variation.

Q: Can ELM 3-300 and ELM 1-300 be used interchangeably with ELM 3-310? A: Both substitutes maintain the same LED type, material, and functional characteristics. Selection depends on whether the 0.300" (7.62mm) height meets the PCB assembly clearance requirements, compared to the 0.310" (7.87mm) height of the main part.

Q: Are there series differences between ELM 3-300 and ELM 1-300? A: ELM 3-300 belongs to the ELM 3 series while ELM 1-300 belongs to the ELM 1 series. Despite this series designation difference, both parts are equivalent parametric substitutes with identical height, LED type, material, and color specifications.

Q: What compliance certifications apply to all listed parts? A: All three parts carry ROHS3 compliance certification with MSL 1 (Unlimited) moisture sensitivity rating, indicating no special storage or handling requirements during standard manufacturing operations.

Q: Are inventory levels a factor in part substitution? A: Inventory quantities (ELM 3-310: 1103 pcs, ELM 3-300: 9596 pcs, ELM 1-300: 8801 pcs) do not determine technical substitution eligibility. Availability should be evaluated based on current supply chain requirements and project lead times independent of engineering compatibility criteria.
