ELM 2-870 LED Standoff Equivalent and Substitute Parts

Part Overview

The ELM 2-870 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a length of 0.870" (22.10mm) and accommodates T1 LED packages. The part is currently active in production status and maintains ROHS3 compliance. Identification of equivalent and substitute parts is necessary when the primary part number becomes unavailable, when inventory constraints require sourcing alternatives, or when procurement optimization requires component consolidation across similar product specifications.

Key Parameters

Substitute Part Grouping Explanation

The substitute part ELM 5-23MM is classified as a parametric equivalent based on the following alignment of critical electrical and mechanical parameters:

Key Substitution Parameters:

• LED Type: Both parts accommodate T1 LED packages
• Material: Both utilize black PVC construction
• Orientation: Both feature vertical mounting configuration
• Lead Count: Both are 2-lead designs
• Manufacturer: Both manufactured by Bivar Inc.
• RoHS Compliance: Both meet ROHS3 compliance requirements
• Moisture Sensitivity: Both maintain MSL 1 (Unlimited) rating

The primary difference between these parts is the length specification: ELM 2-870 measures 0.870" (22.10mm) while ELM 5-23MM measures 0.910" (23.11mm), representing a dimensional variance of 0.040" (1.01mm). This dimensional tolerance falls within typical mechanical mounting clearances for most LED standoff applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 2-870 and ELM 5-23MM are active production parts from Bivar Inc. with identical RoHS3 compliance and MSL 1 ratings. The parts are suitable for direct substitution in applications where the 0.040" (1.01mm) length difference does not create mechanical interference or functional constraints. Selection between these parts should be based on availability, lead time requirements, and specific board layout clearance specifications. Both parts maintain identical electrical and environmental performance characteristics as specified by their compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can ELM 5-23MM be used in place of ELM 2-870?

A: The ELM 5-23MM serves as a parametric equivalent for the ELM 2-870. Both parts share identical LED type (T1), material (black PVC), orientation (vertical), lead count (2-lead), and compliance characteristics. The dimensional difference of 0.040" (1.01mm) in length may be accommodated in most applications. Verify that mounting clearances and PCB footprint constraints permit the slightly increased standoff height of the ELM 5-23MM before implementation.

Q: What parameters define the substitution between these parts?

A: Substitution is valid based on matching: LED type classification (T1), material composition (black PVC), mechanical orientation (vertical mounting), lead configuration (2-lead), manufacturer (Bivar Inc.), regulatory compliance (ROHS3), and environmental rating (MSL 1). These parameters ensure electrical and mechanical compatibility for equivalent functional performance.

Q: Are there any compliance or certification considerations?

A: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings. No additional testing or certification review is required when substituting between these parts from a regulatory standpoint.

Q: How does the length difference affect application suitability?

A: The 0.040" (1.01mm) length differential represents a minor dimensional variance. Applications with restricted vertical clearance or tight PCB spacing may require evaluation. Standard LED mounting applications typically accommodate this tolerance range without modification.

Q: Which part should be selected for new designs?

A: Selection should be based on current inventory availability, supplier lead times, and specific mechanical clearance requirements of the application. Both parts are active products and equally suitable for new design implementation when dimensional constraints are satisfied.
