ELM 3-785

Part Overview

The ELM 3-785 is a T1 3/4 LED standoff manufactured by Bivar Inc., constructed from black PVC material with a length of 0.785" (19.94mm). This component is currently in active production status and is ROHS3 compliant. Alternative models may be required due to inventory constraints, application-specific dimensional requirements, or supply chain considerations for equivalent functional performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution between ELM 3-785 and ELM 1-820 is permissible based on the following allowed parameters:

Common Parameters:

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

Varying Parameter:

• Length: ELM 3-785 at 0.785" (19.94mm) versus ELM 1-820 at 0.820" (20.83mm)

The 0.035" (0.89mm) length differential between these parts permits substitution in applications where this dimensional variance is acceptable within the mechanical tolerance stack-up of the assembly.

Parameter Comparison

Engineering Selection Recommendations

Both ELM 3-785 and ELM 1-820 are active products from the same manufacturer with identical ROHS3 compliance and moisture sensitivity ratings. Selection between these parts should be based on the dimensional requirement of the application. The ELM 3-785 with its shorter 0.785" length is suitable for space-constrained assemblies, while the ELM 1-820 with its 0.820" length accommodates applications requiring slightly greater standoff height. Both parts meet the same regulatory compliance standards and are suitable for equivalent functional applications within dimensional constraints.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between ELM 3-785 and ELM 1-820? A: The primary difference is the length specification. ELM 3-785 measures 0.785" (19.94mm) while ELM 1-820 measures 0.820" (20.83mm). All other electrical and mechanical parameters are equivalent.

Q: Can ELM 1-820 be substituted for ELM 3-785 in my assembly? A: Substitution is permissible only if your mechanical design tolerates the additional 0.035" (0.89mm) in height. Review your PCB layout, enclosure clearance, and component spacing to confirm compatibility.

Q: Are there any regulatory or compliance differences between these parts? A: No. Both parts carry identical ROHS3 compliance certification and Moisture Sensitivity Level 1 rating.

Q: What LED type do these standoffs accommodate? A: Both parts are designed for T1 3/4 LED packages.

Q: Are these parts still in production? A: Yes. Both ELM 3-785 and ELM 1-820 maintain active product status with Bivar Inc.
