ELM 4-690 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-690 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.690" (17.53mm) length. This component is an active product with full RoHS3 compliance and MSL Level 1 rating, indicating unlimited moisture sensitivity tolerance. Substitute parts are identified based on matching electrical and mechanical parameters within the ELM series LED standoff product line, enabling component interchangeability when the primary part is unavailable or when design specifications permit dimensional tolerance.

Substitute Part Grouping Explanation

Substitute parts for the ELM 4-690 are qualified based on the following criteria:

Matching Parameters:

• LED Type: T1 (all substitutes)
• Material: PVC (all substitutes)
• Color: Black (all substitutes)
• Manufacturer: Bivar Inc. (all substitutes)
• RoHS Status: ROHS3 Compliant (all substitutes)
• Moisture Sensitivity Level: 1 (Unlimited) (all substitutes)
• Mounting Orientation: Vertical (all substitutes)

Allowable Variation:

• Length tolerance: Substitutes operate within 0.665" to 0.690" (16.89mm to 17.53mm) range, representing a maximum variance of 0.025" (0.64mm)

The ELM 4-690 qualifies two substitute parts from the ELM 2 series: ELM 2-665 and ELM 2-17MM. Both maintain identical electrical and material specifications while operating within acceptable mechanical dimensional tolerances for T1 LED standoff applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (ELM 4-690): Use the ELM 4-690 when the exact 0.690" (17.53mm) length specification is required for PCB layout, mechanical clearance, or assembly fixture compatibility. This part maintains active product status with full inventory availability.

Secondary Selection (ELM 2-17MM): The ELM 2-17MM operates at 0.670" (17.02mm) length, representing a 0.020" (0.51mm) reduction from the main part. This substitute is suitable when minor height reduction is acceptable within design tolerances. This part offers the highest inventory availability at 1815 units.

Tertiary Selection (ELM 2-665): The ELM 2-665 operates at 0.665" (16.89mm) length, representing a 0.025" (0.64mm) reduction from the main part. This substitute is suitable when maximum allowable height reduction is acceptable. All three parts maintain identical RoHS3 compliance and MSL Level 1 ratings, ensuring equivalent environmental and regulatory performance.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-665 and ELM 2-17MM be used interchangeably with ELM 4-690?

A: Yes, within design tolerance limits. Both substitutes maintain identical LED type (T1), material (PVC), color (Black), and compliance certifications (RoHS3, MSL 1). Length variations are 0.025" and 0.020" respectively, which may be acceptable depending on PCB layout and mechanical clearance requirements.

Q: What is the maximum length difference between the main part and substitutes?

A: The ELM 2-665 represents the maximum allowable variation at 0.025" (0.64mm) shorter than the ELM 4-690. The ELM 2-17MM is 0.020" (0.51mm) shorter.

Q: Are all three parts RoHS3 compliant?

A: Yes. The ELM 4-690, ELM 2-665, and ELM 2-17MM are all ROHS3 Compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute has the best inventory availability?

A: The ELM 2-17MM has the highest inventory at 1815 units in stock, compared to 882 units for ELM 2-665 and 1168 units for the main ELM 4-690.

Q: Do the substitutes use the same packaging format?

A: Yes. All three parts are packaged in Bag format, maintaining consistent handling and storage requirements.

Q: What series differences exist between ELM 4-690 and the ELM 2 substitutes?

A: The ELM 4-690 belongs to the ELM 4 series, while ELM 2-665 and ELM 2-17MM belong to the ELM 2 series. Series designation reflects internal product line organization but does not affect electrical or mechanical compatibility for these standoff applications.
