ELM 1-280 Equivalent and Substitute Parts Reference

Part Overview

The ELM 1-280 is a T1 3/4 LED standoff in black PVC with a 0.280" (7.11mm) height, manufactured by Bivar Inc. This component is currently active and maintains full inventory availability. LED standoffs serve as mechanical mounting and alignment structures for T1 3/4 LED packages in electronic assemblies. Substitute parts become necessary when specific height requirements are marginally different, inventory constraints require alternative sourcing, or design revisions require component optimization.

Substitute Part Grouping Explanation

The ELM 3-285 qualifies as a parametric equivalent based on strict alignment of core mechanical and material parameters. Both parts share identical LED package compatibility (T1 3/4), material composition (black PVC), color specification, and RoHS compliance status. The height differential of 0.005" (0.13mm) between the 0.280" ELM 1-280 and the 0.285" ELM 3-285 falls within acceptable mechanical tolerance for LED standoff applications where minor vertical spacing variations do not affect circuit functionality or mechanical clearance requirements. Both components operate under identical Moisture Sensitivity Level (MSL 1) and regulatory frameworks (ECCN EAR99). The substitution is valid when designs can accommodate the marginal height increase or when inventory and sourcing requirements necessitate the alternative.

Parameter Comparison

Engineering Selection Recommendations

Both ELM 1-280 and ELM 3-285 maintain active product status with full RoHS3 compliance and identical regulatory classifications. Component selection depends on design-specific height requirements. The ELM 1-280 should be selected for assemblies requiring the 0.280" (7.11mm) specification. The ELM 3-285 is suitable for applications where the 0.285" (7.24mm) height is acceptable and provides greater inventory availability (4749 units in stock versus 945 units). Both parts satisfy identical environmental and regulatory requirements with MSL 1 classification, supporting unlimited moisture exposure without degradation.

Frequently Asked Questions (FAQ)

Can ELM 3-285 directly replace ELM 1-280 in existing designs? Substitution is valid only if the design allows for a 0.005" (0.13mm) height increase. This marginal vertical spacing change does not affect standard LED mounting or circuit clearance in most applications, but verification against specific mechanical drawing constraints is required.

What are the primary differences between these standoffs? The parts differ only in height specification (0.280" versus 0.285") and series designation (ELM 1 versus ELM 3). All other parameters—LED compatibility, material, color, regulatory status, and moisture sensitivity—are identical.

Are there any packaging or inventory advantages? ELM 3-285 provides significantly higher inventory levels (4749 units) compared to ELM 1-280 (945 units), making it preferable for high-volume procurement when height tolerance permits substitution.

Do these parts share identical environmental specifications? Both parts carry MSL 1 rating, indicating unlimited moisture exposure capability without desiccant requirements. Both comply with ROHS3 and carry identical ECCN classifications (EAR99).

What is the mechanical compatibility constraint between these parts? Mechanical compatibility depends exclusively on the 0.005" height tolerance. LED package compatibility (T1 3/4) is identical, and PVC material properties ensure equivalent mechanical performance. Substitution requires design review of vertical spacing margins only.
