ELM 3-405 Equivalent & Substitute Parts

Part Overview

The ELM 3-405 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.405" (10.29mm) length. This component is constructed from black PVC material and is classified as an active product with full RoHS3 compliance. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative components that maintain functional equivalence within specified mechanical and electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 3-405 is determined by the following parameters:

Primary Substitution Criteria:

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

Secondary Consideration:

• Length tolerance: Substitute parts must fall within the mechanical envelope requirements of the application. Length variations between 0.385" (9.78mm) and 0.405" (10.29mm) are acceptable within the ELM series standoff family.

The ELM 1-10MM and ELM 1-385 are classified as parametric equivalents because they share identical LED type, material composition, color specification, and compliance certifications with the main part, with length variations of ±0.020" (0.51mm) and ±0.020" (0.51mm) respectively.

Engineering Selection Recommendations

ELM 3-405 (Primary Selection) Select this part when the specified length of 0.405" (10.29mm) is a critical design requirement. This part maintains active product status with full inventory availability of 988 pieces.

ELM 1-10MM (First Alternative) This substitute is suitable when a length of 0.390" (9.91mm) is acceptable within the application's mechanical tolerance. The 0.015" (0.38mm) reduction in length maintains all electrical and compliance specifications. Inventory availability is 947 pieces.

ELM 1-385 (Second Alternative) This substitute is suitable when a length of 0.385" (9.78mm) is acceptable within the application's mechanical tolerance. The 0.020" (0.51mm) reduction in length maintains all electrical and compliance specifications. Inventory availability is 750 pieces.

All three parts maintain identical RoHS3 compliance, MSL rating, and material composition, ensuring regulatory and environmental compatibility across selections.

Frequently Asked Questions (FAQ)

Q: Can ELM 1-10MM be used in place of ELM 3-405? A: Yes, provided the application mechanical envelope accommodates a 0.015" (0.38mm) shorter standoff. All electrical, material, and compliance parameters are identical.

Q: What is the maximum length difference between substitute parts? A: The maximum length difference between ELM 3-405 and ELM 1-385 is 0.020" (0.51mm). Selection depends on the application's tolerance for vertical height variation.

Q: Are all substitute parts RoHS3 compliant? A: Yes. ELM 3-405, ELM 1-10MM, and ELM 1-385 are all ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Do substitute parts use the same packaging? A: Yes. All parts are supplied in Bag packaging format.

Q: What is the LED type specification for all parts? A: All parts use T1 3/4 LED type with black PVC construction.

Q: Can I mix different substitute parts in a single assembly? A: Mixing parts with different lengths (0.405", 0.390", 0.385") in the same assembly is not recommended unless the application design explicitly permits height variation between standoff positions.

Q: Are there any electrical performance differences between the main part and substitutes? A: No. All parts are mechanically different only in length. Electrical performance and material properties are identical.
