ELM 3-850

Part Overview

The ELM 3-850 is a T1 3/4 LED standoff manufactured by Bivar Inc., constructed from black PVC material with a length of 0.850" (21.59mm). This component is currently in active product status and maintains ROHS3 compliance. Finding alternative models becomes necessary when ELM 3-850 units are unavailable from inventory or when sourcing requirements demand evaluation of equivalent alternatives that meet the same functional and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The ELM 1-820 qualifies as a parametric equivalent based on the following critical specifications:

Matching Parameters:

• LED Type: T1 3/4 (identical functional form factor)
• Material: Black PVC (identical construction)
• Color: Black (identical visual specification)
• Product Status: Active (both current production items)
• RoHS Status: ROHS3 Compliant (identical regulatory compliance)
• MSL Rating: 1 (Unlimited) (identical moisture sensitivity classification)
• Packaging: Bag (identical delivery format)
• Manufacturer: Bivar Inc. (same manufacturer)

Variable Parameter:

• Length: 0.820" (20.83mm) versus 0.850" (21.59mm) — represents a 0.030" (0.76mm) dimensional difference

Substitution is valid when mechanical tolerance requirements of the application accommodate the 0.030" length differential between these standoff heights.

Parameter Comparison

Engineering Selection Recommendations

Both ELM 3-850 and ELM 1-820 maintain active product status from Bivar Inc. and achieve identical ROHS3 compliance certification and MSL 1 ratings. Selection between these parts depends on mechanical fit validation within the target application. The 0.030" length differential is the sole distinguishing factor; this variance requires assessment against the specific height tolerance requirements of the assembly into which the LED standoff will be integrated. Both parts are suitable for applications where this dimensional tolerance is acceptable.

Frequently Asked Questions (FAQ)

Can ELM 1-820 replace ELM 3-850 directly? Direct substitution is possible only when the application mechanical design tolerates a 0.030" (0.76mm) reduction in standoff height. The LED type, material composition, color, and regulatory compliance remain identical between the two parts.

What is the primary difference between these parts? The ELM 1-820 is 0.030" shorter than the ELM 3-850. Both are T1 3/4 LED standoffs manufactured from black PVC with identical electrical and environmental ratings.

Are both parts currently available? Both ELM 3-850 and ELM 1-820 maintain active product status. Inventory availability should be confirmed with the supplier, as this specification does not guarantee current stock levels.

Do these parts have different RoHS certifications? No. Both ELM 3-850 and ELM 1-820 comply with ROHS3 standards and carry MSL 1 (Unlimited) moisture sensitivity ratings.

What is the difference between the ELM 3 and ELM 1 series designations? The series designation reflects the base product numbering structure within Bivar Inc.'s product line. Functionally equivalent parts may exist across different series identifiers based on dimensional variants.
