LTM-390 Equivalent & Substitute Parts

Part Overview

The LTM-390 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., constructed from crystalline polymer material with a 0.390" (9.91mm) length. This component is designed for vertical mounting applications requiring precision LED alignment and mechanical support. The part maintains Active product status and is RoHS3 compliant. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design specifications permit material or dimensional variations within established tolerances.

Substitute Part Grouping Explanation

Substitute parts for the LTM-390 are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• LED Type: T1 or T1 3/4 compatibility
• Color: Black
• Length: Within acceptable mechanical tolerance range (0.374" to 0.394")
• Material: Polymer-based construction (crystalline polymer or nylon)
• RoHS Compliance: ROHS3 Compliant
• Packaging: Bag format

The substitute parts listed (705820095 and 705820100) satisfy these criteria through equivalent LED type support, matching color specification, and compliance certifications. Length variations of ±0.016" from the nominal 0.390" specification remain within standard mechanical tolerances for LED standoff applications. Material substitution from crystalline polymer to nylon is permissible where both materials provide equivalent mechanical support and electrical isolation properties for T1/T1 3/4 LED mounting.

Parameter Comparison

Engineering Selection Recommendations

LTM-390 (Bivar Inc.): Select this part when crystalline polymer material is specified in design documentation or when the exact 0.390" length is required for mechanical fit constraints. This part maintains Active status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

705820095 (Würth Elektronik): This substitute provides T1/T1 3/4 LED standoff functionality with nylon construction and 0.374" length. The 0.016" shorter dimension accommodates applications where reduced standoff height is acceptable. RoHS3 compliance and REACH Unaffected status are confirmed. Select when Würth Elektronik sourcing is preferred and length tolerance permits the shorter dimension.

705820100 (Würth Elektronik): This substitute provides T1/T1 3/4 LED standoff functionality with nylon construction and 0.394" length. The 0.004" longer dimension remains within standard mechanical tolerances and provides the closest dimensional match to the LTM-390. RoHS3 compliance and REACH Unaffected status are confirmed. Select when Würth Elektronik sourcing is preferred and dimensional tolerance accommodates the longer specification.

All three parts maintain Active product status, identical ECCN and HTSUS classifications, and equivalent electrical isolation properties for LED mounting applications.

Frequently Asked Questions (FAQ)

Q: Can 705820095 or 705820100 be used as direct replacements for LTM-390?

A: Yes, both Würth Elektronik parts function as parametric equivalents for T1/T1 3/4 LED standoff applications. The primary differences are material composition (nylon versus crystalline polymer) and length variation. Design specifications must permit these variations for direct substitution.

Q: What is the significance of the length differences between these parts?

A: The LTM-390 measures 0.390" (9.91mm), while 705820095 measures 0.374" (9.50mm) and 705820100 measures 0.394" (10.00mm). These variations fall within standard mechanical tolerances for LED standoff components. The application's mechanical constraints determine which length is acceptable. Verify PCB layout and LED lead clearance requirements before selection.

Q: Are there material compatibility concerns when substituting crystalline polymer with nylon?

A: Both crystalline polymer and nylon provide equivalent mechanical support and electrical isolation for T1/T1 3/4 LED mounting. Material selection depends on application-specific requirements such as temperature range, chemical exposure, or mechanical stress. Both materials are RoHS3 compliant and suitable for standard LED mounting applications.

Q: Do all three parts share the same compliance certifications?

A: Yes. All three parts are RoHS3 compliant, classified under ECCN EAR99, and assigned HTSUS code 3926.90.9985. The Würth Elektronik parts carry additional REACH Unaffected status. Compliance requirements are satisfied across all three options.

Q: What inventory considerations apply to these substitutes?

A: LTM-390 has 1,086 pieces in stock. 705820095 has 1,578 pieces in stock. 705820100 has 6,138 pieces in stock. Availability varies by supplier and sourcing channel. Verify current inventory status with your component distributor before finalizing procurement decisions.

Q: Are there packaging differences between these parts?

A: All three parts are supplied in Bag packaging format. No packaging conversion or special handling differences apply between the LTM-390 and its substitutes.
