ELM 3-860 Equivalent & Substitute Parts

Part Overview

The ELM 3-860 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 0.860" (21.84mm) length specification. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when inventory availability requires alternative sourcing or when application-specific length tolerances permit functional equivalence within the T1 3/4 LED standoff category.

Substitute Part Grouping Explanation

Substitute parts for the ELM 3-860 are identified based on the following criteria:

Mandatory Matching Parameters:

• LED Type: T1 3/4
• Material: Black PVC
• Mounting Style: Vertical
• Manufacturer: Bivar Inc.
• Product Status: Active
• RoHS Compliance: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Allowable Variation Parameter:

• Length: Within the ELM series standoff range (0.820" to 0.860")

The ELM 1-820 qualifies as a parametric equivalent because it maintains all mandatory matching parameters while operating within the acceptable length tolerance band for T1 3/4 vertical LED standoff applications. The 0.040" (1.01mm) length difference represents a minor dimensional variation that does not affect the core functional classification of the component.

Parameter Comparison

Engineering Selection Recommendations

ELM 3-860 Primary Selection: Select the ELM 3-860 when the 0.860" (21.84mm) length specification is required by design documentation or PCB layout constraints. This part maintains active production status with confirmed inventory availability (1132 pcs in stock).

ELM 1-820 Substitute Selection: The ELM 1-820 is functionally equivalent for applications where the 0.040" (1.01mm) length reduction is acceptable within mechanical tolerance bands. This substitute is appropriate when:

• Design specifications permit length variation within the T1 3/4 standoff range
• Inventory availability of the primary part is constrained
• Both parts maintain identical RoHS3 compliance and MSL 1 ratings

Both parts are manufactured by Bivar Inc. and carry active product status with full regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: What determines if ELM 1-820 can replace ELM 3-860?

A: Substitution is valid when the application tolerates a 0.040" (1.01mm) length difference. Both parts share identical LED type (T1 3/4), material (black PVC), mounting orientation (vertical), and compliance ratings (ROHS3, MSL 1). The length variation is the only dimensional difference between these Bivar Inc. standoffs.

Q: Are there any compliance differences between these parts?

A: No. Both ELM 3-860 and ELM 1-820 carry ROHS3 compliance certification and MSL 1 (unlimited moisture sensitivity) ratings. They are equivalent from a regulatory and environmental standpoint.

Q: Can these parts be used interchangeably in all applications?

A: Interchangeability depends on mechanical clearance and height requirements in the specific PCB assembly. The 0.040" length difference must be evaluated against board layout, component spacing, and enclosure constraints. Verify that the shorter ELM 1-820 does not create clearance issues in your assembly.

Q: What is the packaging format for both parts?

A: Both the ELM 3-860 and ELM 1-820 are supplied in bag packaging, suitable for standard component handling and storage procedures.

Q: Are both parts currently available?

A: Yes. ELM 3-860 has 1132 pcs in stock, and ELM 1-820 has 1983 pcs in stock as new original inventory.
