ELM 2-510 Equivalent & Substitute Parts

Part Overview

The ELM 2-510 is a T1 LED standoff manufactured by Bivar Inc., featuring a vertical surface-mount configuration with a 0.510" (12.95mm) length. This component is constructed from black PVC material and is designed for 3mm LED applications with two-lead configuration. The part maintains Active product status and is ROHS3 compliant, ensuring compliance with modern environmental regulations. Substitute parts are identified to provide alternatives when the primary model is unavailable or when design specifications permit slight dimensional variations within the allowed parameter tolerance range.

Substitute Part Grouping Explanation

The ELM 2-510 has two identified substitute parts: ELM 2-500 and ELM 5-485. Substitution eligibility is determined by strict adherence to the following parameters:

Primary Substitution Criteria:

• LED Type: T1 (all parts match)
• Material: Black PVC (all parts match)
• Configuration: Vertical surface-mount, 3mm, 2-lead (all parts match)
• RoHS Status: ROHS3 Compliant (all parts match)
• Moisture Sensitivity Level: MSL 1 (all parts match)

Dimensional Tolerance Parameter:

• Length variation: Parts are grouped as substitutes based on allowable length differences measured in inches and millimeters. The ELM 2-510 operates at 0.510" (12.95mm), with substitutes ranging from 0.485" to 0.500".

The ELM 2-500 and ELM 5-485 maintain functional equivalence through identical LED specifications, material composition, and compliance certifications while permitting dimensional variance within the mechanical design envelope of the mounting application.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ELM 2-510, ELM 2-500, and ELM 5-485—carry Active product status and maintain ROHS3 compliance. Selection between these parts is governed by mechanical length requirements and mounting tolerance specifications. The ELM 2-510 operates at the maximum specified length of 0.510 inches. The ELM 2-500 provides a 0.010-inch reduction from the primary part, while the ELM 5-485 offers a 0.025-inch reduction. All parts share identical electrical functionality, material properties, and regulatory certifications, enabling substitution where mechanical envelope constraints permit dimensional variance.

Frequently Asked Questions (FAQ)

Q: What are the primary differences between ELM 2-510 and its substitutes?

A: The ELM 2-510, ELM 2-500, and ELM 5-485 are differentiated solely by their axial lengths: 0.510", 0.500", and 0.485" respectively. All other electrical, mechanical, and compliance parameters remain identical across the three parts.

Q: Can the ELM 2-500 be used in place of the ELM 2-510?

A: The ELM 2-500 is mechanically substitutable for the ELM 2-510 when the application permits a 0.010-inch (0.25mm) reduction in standoff length. Both parts maintain identical LED type, material composition, configuration, and compliance certifications.

Q: What is the maximum length difference between substitute parts?

A: The maximum length difference across the substitute group is 0.025 inches (0.63mm), occurring between the ELM 2-510 (0.510") and ELM 5-485 (0.485"). This difference must be evaluated against the mechanical design requirements of the specific application.

Q: Are all parts in this substitution group ROHS3 compliant?

A: Yes. The ELM 2-510, ELM 2-500, and ELM 5-485 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), enabling unrestricted use in regulated applications.

Q: What packaging format is provided for these parts?

A: All three parts are supplied in bag packaging, consistent with standard component distribution for LED standoff assemblies.
