ELM 1-420 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 1-420 is a T1 3/4 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.420" (10.67mm) length. This component is classified as an active product and serves as a mechanical mounting solution for LED applications requiring vertical orientation with short-reach standoff characteristics.

Substitute parts become necessary when the primary part experiences inventory constraints, extended lead times, or when design specifications allow for minor dimensional variations within acceptable tolerances. The ELM 1-420 maintains full compatibility with parametric equivalents that share identical electrical and mechanical core specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 1-420 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 3/4 (must match exactly)
• Material: Black PVC (must match exactly)
• Orientation: Vertical (must match exactly)
• RoHS Status: ROHS3 Compliant (must match exactly)
• Moisture Sensitivity Level: 1 (Unlimited) (must match exactly)
• Manufacturer: Bivar Inc. (must match exactly)

Secondary Consideration:

• Length tolerance: Substitute parts may vary within the range of 0.420" to 0.440" (10.67mm to 11.18mm), representing a maximum dimensional variance of 0.020" (0.51mm)

The ELM 1-420 has two identified parametric equivalents: ELM 1-11MM and ELM 3-440. Both maintain all primary compatibility criteria while introducing minor length variations that remain within acceptable mechanical tolerances for LED standoff applications.

Parameter Comparison

Engineering Selection Recommendations

ELM 1-420 (Primary Part) Select this part when the exact 0.420" (10.67mm) length specification is required by design documentation or when inventory availability is confirmed at required quantities.

ELM 1-11MM (First Substitute) This part introduces a 0.010" (0.25mm) length increase to 0.430" (10.92mm). Selection is appropriate when design tolerances accommodate this dimensional variance and when ELM 1-420 inventory is unavailable. Current inventory of 1475 units provides adequate availability.

ELM 3-440 (Second Substitute) This part introduces a 0.020" (0.51mm) length increase to 0.440" (11.18mm), representing the maximum allowable dimensional variance within the substitute group. Selection is appropriate when design tolerances accommodate this dimensional variance. Current inventory of 22638 units provides maximum availability within the substitute group.

All three parts maintain identical RoHS3 compliance, MSL rating, and active product status, ensuring regulatory and environmental consistency across substitution scenarios.

Frequently Asked Questions (FAQ)

Q: What is the maximum length variation between ELM 1-420 and its substitutes? A: The maximum length variation is 0.020" (0.51mm), occurring between ELM 1-420 at 0.420" (10.67mm) and ELM 3-440 at 0.440" (11.18mm). ELM 1-11MM represents an intermediate option at 0.430" (10.92mm).

Q: Are all substitute parts manufactured by the same company? A: Yes. ELM 1-420, ELM 1-11MM, and ELM 3-440 are all manufactured by Bivar Inc., ensuring consistent quality standards and design philosophy across the substitute group.

Q: Do substitute parts maintain the same environmental compliance ratings? A: Yes. All three parts are ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring identical environmental and moisture sensitivity characteristics.

Q: Can ELM 3-440 be used as a direct replacement for ELM 1-420? A: ELM 3-440 is a parametric equivalent with identical electrical and material specifications. The 0.020" (0.51mm) length difference must be evaluated against specific design tolerances and mechanical constraints of the application before substitution.

Q: What packaging format is used for all substitute parts? A: All parts in this substitute group are supplied in bag packaging, maintaining consistent handling and storage requirements.

Q: Which substitute part has the highest current inventory availability? A: ELM 3-440 has the highest inventory at 22638 units, followed by ELM 1-11MM at 1475 units, and ELM 1-420 at 1118 units.
