ELM 3-420 Equivalent & Substitute Parts

Part Overview

The ELM 3-420 is an active T1 3/4 LED standoff manufactured by Bivar Inc., featuring a vertical mount configuration with a 0.420" (10.67mm) length. This component is constructed from black PVC material and is ROHS3 compliant. Alternative part numbers are identified to address supply chain requirements, inventory availability, or specific tolerance needs within the allowable parametric range.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 3-420 are qualified based on the following common parametric criteria:

• LED Type: T1 3/4 form factor (maintained across all substitutes)
• Mount Configuration: Vertical (SR VERT) surface mount design
• Material & Color: Black PVC construction
• Manufacturer: Bivar Inc. (same manufacturer, ensuring design consistency)
• Compliance: ROHS3 compliant with MSL 1 rating

The substitute parts ELM 1-11MM and ELM 3-440 differ from the main part in length specification (0.430" and 0.440" respectively versus the 0.420" nominal). These length variations remain within the allowable mechanical tolerance range for T1 3/4 LED standoff applications. Both substitutes maintain identical electrical characteristics, material composition, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Selection between ELM 3-420 and its substitutes is determined by mechanical length requirements and availability:

ELM 3-420 (0.420" / 10.67mm): Primary specification when exact nominal length is required. Current inventory: 664 pieces.

ELM 1-11MM (0.430" / 10.92mm): Suitable when a 0.010" (0.25mm) longer standoff is acceptable within board layout tolerance. ELM 1 series designation indicates series interchangeability with ELM 1-series applications. Current inventory: 1475 pieces.

ELM 3-440 (0.440" / 11.18mm): Suitable when a 0.020" (0.51mm) longer standoff is acceptable within board layout tolerance. Maintains ELM 3 series continuity. Current inventory: 22638 pieces.

All three parts are active products with full ROHS3 compliance and unlimited moisture sensitivity rating. Selection should be based on PCB design clearance and functional height requirements.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between ELM 3-420 and its substitutes?

A: The primary difference is length specification. ELM 3-420 measures 0.420" (10.67mm), while ELM 1-11MM measures 0.430" (10.92mm) and ELM 3-440 measures 0.440" (11.18mm). All other electrical and mechanical parameters are identical.

Q: Can ELM 1-11MM be used interchangeably with ELM 3-420?

A: ELM 1-11MM is mechanically compatible when the additional 0.010" (0.25mm) length does not violate board design constraints or component clearance requirements. Both parts have identical LED type, material, color, and compliance ratings.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. ELM 3-420, ELM 1-11MM, and ELM 3-440 are all ROHS3 compliant with MSL 1 (Unlimited) rating, ensuring equivalent environmental and regulatory compliance.

Q: What packaging format is used for these parts?

A: All parts are supplied in bag packaging format.

Q: If I need the exact 0.420" length, which part should I order?

A: Order ELM 3-420 when the nominal 0.420" (10.67mm) specification is required. Verify inventory availability before placing orders to ensure supply continuity.

Q: How do I determine which substitute is compatible with my design?

A: Compare your PCB standoff height requirement against the available lengths: 0.420" (ELM 3-420), 0.430" (ELM 1-11MM), or 0.440" (ELM 3-440). Ensure selected length accommodates circuit board tolerances and does not create interference with mounted components or enclosure constraints.
