ELM 1-11MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 1-11MM is a T1 3/4 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.430" (10.92mm) 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 positioning.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or when application requirements permit tolerance variations in standoff length. The ELM 1-11MM has identified parametric equivalents within the ELM 3 series that maintain functional compatibility through shared core specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 1-11MM is determined by the following mandatory parameters:

Core Compatibility Parameters:

• LED Type: T1 3/4 (must match exactly)
• Material: Black PVC (must match exactly)
• Orientation: Vertical (SR VERT configuration)
• Color: Black (must match exactly)
• RoHS Compliance: ROHS3 Compliant (must match or exceed)
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameter:

• Length: ±0.010" tolerance permitted (0.420" to 0.460" range)

The ELM 3-440 and ELM 3-450 substitute parts satisfy all core compatibility parameters. Both maintain identical LED type, material composition, orientation, color specification, and environmental compliance ratings. Length variations of 0.010" and 0.020" respectively fall within acceptable mechanical tolerance for standoff applications where precise height is not critical to circuit board assembly.

Engineering Selection Recommendations

Primary Selection (ELM 1-11MM): Use the primary part number when exact 0.430" (10.92mm) standoff height is required for circuit board assembly specifications. This part maintains active product status with full inventory availability (1475 pcs).

Secondary Selection (ELM 3-440): The ELM 3-440 substitute provides a 0.010" length increase (0.440" / 11.18mm). Select this part when the primary part is unavailable and application tolerance permits a +0.010" height variation. This substitute offers the highest inventory availability (22638 pcs) and maintains all compliance certifications.

Tertiary Selection (ELM 3-450): The ELM 3-450 substitute provides a 0.020" length increase (0.450" / 11.43mm). Select this part when both primary and secondary options are unavailable and application tolerance permits a +0.020" height variation. This substitute maintains active status with substantial inventory (8972 pcs) and includes REACH Unaffected designation.

All three parts maintain ROHS3 compliance, MSL 1 rating, and identical material and LED specifications, ensuring functional equivalence within specified length tolerances.

Frequently Asked Questions (FAQ)

Q: Can ELM 3-440 and ELM 3-450 be used interchangeably with ELM 1-11MM?

A: Yes, within application tolerance limits. Both substitutes maintain identical LED type (T1 3/4), material (Black PVC), orientation (vertical), and color specifications. The length differences (0.010" and 0.020" respectively) are the only variables. Substitution is valid only when circuit board assembly design permits these height variations.

Q: What is the maximum allowable length variation for substitution?

A: Based on the provided substitute parts, length variations up to 0.020" (from 0.430" to 0.450") are documented as acceptable. Applications requiring tighter height tolerance must use the primary ELM 1-11MM part number.

Q: Are all three parts RoHS compliant?

A: Yes. The ELM 1-11MM, ELM 3-440, and ELM 3-450 are all ROHS3 Compliant. Additionally, the ELM 3-450 carries REACH Unaffected designation.

Q: What is the Moisture Sensitivity Level for these parts?

A: All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Are there packaging differences between the main part and substitutes?

A: No. All three parts are supplied in Bag packaging format.

Q: Which substitute should be selected for new designs?

A: For new designs, verify application tolerance requirements. If exact 0.430" height is mandatory, specify ELM 1-11MM. If ±0.010" tolerance is acceptable, ELM 3-440 offers superior inventory availability. If ±0.020" tolerance is acceptable, ELM 3-450 provides additional compliance documentation (REACH Unaffected).
