LTM-320 LED Standoff Equivalent & Substitute Parts

Part Overview

The LTM-320 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., constructed from crystalline polymer material in black color with a 0.320" (8.13mm) length. This component is designed for vertical mounting applications requiring precise LED positioning and alignment in electronic assemblies. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production environments. Equivalent substitute parts may be required due to inventory availability, supply chain considerations, or specific application requirements where alternative material compositions or dimensional tolerances are acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTM-320 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 or T1 3/4 configuration
• Color: Black
• Length Tolerance: Within acceptable mechanical fit range (0.315" to 0.335")
• Material: Polymer-based construction (crystalline polymer or nylon acceptable)
• Compliance: ROHS3 compliant
• Packaging: Bag format

The substitute parts listed (705820080 and 705820085) are classified as parametric equivalents because they satisfy all primary compatibility criteria. Both substitute parts are manufactured by Würth Elektronik, support the same LED types (T1/T1 3/4), maintain black color specification, and achieve ROHS3 compliance. The material composition differs (nylon versus crystalline polymer), but both are polymer-based standoff materials suitable for LED mounting applications. Length variations (0.315" and 0.335") fall within acceptable mechanical tolerance ranges for vertical LED standoff applications.

Parameter Comparison

Engineering Selection Recommendations

705820080 Selection Criteria: This Würth Elektronik substitute features a 0.315" (8.00mm) length, representing a 0.005" (0.13mm) reduction from the main part specification. The nylon material composition maintains structural integrity for T1/T1 3/4 LED mounting. Active product status and ROHS3 compliance ensure compatibility with current manufacturing standards. This option is suitable for applications where the shorter standoff height accommodates mechanical constraints or PCB layout requirements.

705820085 Selection Criteria: This Würth Elektronik substitute features a 0.335" (8.50mm) length, representing a 0.015" (0.37mm) increase from the main part specification. The nylon material composition provides equivalent mechanical performance for LED positioning. Active product status and ROHS3 compliance maintain regulatory alignment. This option is suitable for applications requiring increased standoff height for component clearance or specific assembly configurations.

General Selection Basis: Both substitute parts maintain Active product status, ensuring ongoing availability and manufacturing support. ROHS3 compliance across all three parts guarantees environmental and regulatory compatibility. The material transition from crystalline polymer to nylon does not compromise functional performance for LED standoff applications, as both materials provide adequate mechanical support and electrical isolation for T1/T1 3/4 LED types. Selection between substitutes should be based on specific mechanical fit requirements determined by PCB layout and assembly specifications.

Frequently Asked Questions (FAQ)

Q: Can 705820080 and 705820085 be used interchangeably with LTM-320?

A: Both parts are parametric equivalents supporting T1/T1 3/4 LED types in black color with ROHS3 compliance. However, the length differences (0.315" and 0.335" versus 0.320") require verification against specific PCB mounting hole spacing and component clearance requirements. Selection depends on mechanical fit within the assembly.

Q: What is the significance of the material change from crystalline polymer to nylon?

A: Both materials are polymer-based and provide equivalent mechanical support and electrical isolation for LED standoff applications. Nylon (UL94 V-2 rated) offers established performance in electronic component mounting. The material substitution does not affect functional compatibility for T1/T1 3/4 LED positioning.

Q: Are all three parts ROHS3 compliant?

A: Yes. LTM-320, 705820080, and 705820085 all maintain ROHS3 compliance, ensuring compatibility with current environmental and regulatory requirements.

Q: What packaging format is used for these parts?

A: All three parts are supplied in Bag packaging format, consistent with standard component distribution for LED standoff assemblies.

Q: How do the length specifications affect component selection?

A: The three parts span a 0.020" (0.50mm) length range: 705820080 at 0.315", LTM-320 at 0.320", and 705820085 at 0.335". Selection must align with PCB design specifications for LED mounting height, component clearance, and assembly requirements. Verify mechanical fit within the target application before substitution.

Q: Are there any moisture sensitivity considerations?

A: LTM-320 carries MSL 1 (Unlimited) rating. The Würth Elektronik substitutes (705820080 and 705820085) list MSL as Not Applicable, indicating no moisture sensitivity restrictions. Both approaches are compatible with standard storage and handling practices.

Q: What is the inventory status for these parts?

A: LTM-320 has 658 pcs in stock. 705820080 has 17,403 pcs in stock. 705820085 has 1,971 pcs in stock. Availability may influence substitution decisions based on project timelines and supply requirements.
