ELM 3-815 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 3-815 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a length of 0.815" (20.70mm) and is classified as an active product with ROHS3 compliance. The need to identify equivalent and substitute parts arises from inventory availability, supply chain considerations, and application-specific requirements where dimensional or performance alternatives may be necessary.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELM 3-815 is determined by strict adherence to the following parameters:

Critical Parameters for Substitution:

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

Allowable Variation:

• Length: The ELM 1-820 substitute part exhibits a length of 0.820" (20.83mm), representing a dimensional variance of 0.005" (0.13mm) from the main part specification. This minor dimensional difference falls within acceptable tolerance ranges for LED standoff applications where precise height matching is not a critical design constraint.

The ELM 1-820 maintains identical electrical, material, and compliance characteristics while differing only in the series designation (ELM 1 versus ELM 3) and the specified length dimension.

Engineering Selection Recommendations

ELM 3-815 Primary Selection: The ELM 3-815 remains the primary component choice when the exact length specification of 0.815" (20.70mm) is a design requirement. This part maintains active product status with full ROHS3 compliance and unlimited moisture sensitivity rating, suitable for standard LED standoff applications.

ELM 1-820 Substitute Selection: The ELM 1-820 serves as a functional equivalent when the 0.005" (0.13mm) length variance is acceptable within the application's mechanical tolerance stack. Both parts share identical electrical characteristics, material composition, compliance certifications, and environmental ratings. The substitute part is appropriate for applications where standoff height is not a critical dimension or where the minor length increase does not conflict with PCB layout constraints.

Both parts maintain ROHS3 compliance and carry identical export classification (EAR99) and tariff codes (8547.20.0000), ensuring regulatory equivalence for procurement and supply chain purposes.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between ELM 3-815 and ELM 1-820?

A: The primary difference is the length specification. The ELM 3-815 measures 0.815" (20.70mm), while the ELM 1-820 measures 0.820" (20.83mm). All other electrical, material, and compliance parameters are identical.

Q: Can ELM 1-820 be used as a direct replacement for ELM 3-815?

A: The ELM 1-820 is a functional substitute when the 0.005" (0.13mm) length difference does not violate application requirements. Applications with strict height tolerances or precise PCB clearance specifications may require the exact ELM 3-815 dimension.

Q: Are both parts RoHS compliant?

A: Yes. Both the ELM 3-815 and ELM 1-820 are ROHS3 compliant and carry identical Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: What packaging format is used for these parts?

A: Both parts are supplied in bag packaging format.

Q: Are there any differences in export classification between these parts?

A: No. Both parts carry identical ECCN classification (EAR99) and HTSUS tariff code (8547.20.0000).

Q: Which part should be selected for new designs?

A: For new designs, select based on the required standoff height. If 0.815" (20.70mm) is specified, use ELM 3-815. If 0.820" (20.83mm) is acceptable or preferred, ELM 1-820 is appropriate. Both parts are active products with equivalent long-term availability.
