ELM 3-290 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 3-290 is a T1 3/4 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.290" (7.37mm) length. This component is designed for vertical mounting applications requiring precise height specifications. The part maintains Active product status and is RoHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity tolerance.

Substitute parts become necessary when the exact ELM 3-290 specification is unavailable, when alternative length specifications are required for PCB layout adjustments, or when inventory constraints necessitate cross-compatible alternatives from the same manufacturer series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 3-290 is determined by the following criteria:

Primary Substitution Parameters:

• Manufacturer: Bivar Inc. (all substitutes from same manufacturer)
• LED Type: T1 3/4 (identical across all alternatives)
• Material: Black PVC (consistent across all alternatives)
• Mounting Style: Vertical (consistent across all alternatives)
• RoHS Compliance: ROHS3 Compliant (maintained across all alternatives)
• Moisture Sensitivity Level: 1 (Unlimited) (maintained across all alternatives)

Variable Parameter:

• Length: 0.290" (7.37mm) in main part; substitutes available in 0.285" (7.24mm) and 0.300" (7.62mm) specifications

The ELM 3-290 substitutes are grouped into two categories: same-series alternatives (ELM 3-285, ELM 3-300) and cross-series alternative (ELM 1-300). All maintain identical LED type, material composition, and compliance certifications. Length variations accommodate different PCB standoff height requirements while preserving all other functional and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

ELM 3-285 (0.285" / 7.24mm): Select when PCB layout requires a shorter standoff height than the ELM 3-290. This part maintains identical series designation (ELM 3), compliance certifications, and material specifications. Suitable for applications with reduced vertical clearance requirements.

ELM 3-300 (0.300" / 7.62mm): Select when PCB layout requires a taller standoff height than the ELM 3-290. This part maintains identical series designation (ELM 3), compliance certifications, and material specifications. Suitable for applications requiring increased vertical spacing.

ELM 1-300 (0.300" / 7.62mm): Select when ELM 3 series parts are unavailable and cross-series compatibility is acceptable. This part maintains identical LED type, material, color, and compliance certifications. The ELM 1 series designation indicates a different base product number but equivalent functional performance for T1 3/4 vertical mounting applications.

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can ELM 3-285 be used as a direct replacement for ELM 3-290?

A: ELM 3-285 is a parametric equivalent with identical specifications except for length. It functions as a substitute only when the shorter 0.285" (7.24mm) height is compatible with your PCB layout and mechanical requirements.

Q: What is the length difference between ELM 3-290 and ELM 3-300?

A: ELM 3-290 measures 0.290" (7.37mm) while ELM 3-300 measures 0.300" (7.62mm), a difference of 0.010" (0.25mm). This variation affects PCB standoff height and must be evaluated against your mechanical design constraints.

Q: Is ELM 1-300 compatible with applications designed for ELM 3-290?

A: ELM 1-300 maintains identical LED type (T1 3/4), material (Black PVC), color, and compliance certifications. Compatibility depends on whether the 0.300" (7.62mm) length and ELM 1 series designation are acceptable for your specific application requirements.

Q: Do all substitute parts maintain the same RoHS and MSL certifications?

A: Yes. All substitute parts (ELM 3-285, ELM 3-300, ELM 1-300) are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the ELM 3-290 certifications.

Q: What packaging format is used for all these parts?

A: All parts are supplied in Bag packaging format, consistent across ELM 3-290 and all substitute alternatives.

Q: Can length be adjusted after installation?

A: No. Length is a fixed mechanical specification determined at manufacturing. Selection must be based on final PCB layout requirements prior to component procurement.
