LTM-440 LED Standoff Equivalent & Substitute Parts

Part Overview

The LTM-440 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., constructed from crystalline polymer in black color with a 0.440" (11.18mm) 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 with MSL 1 rating, indicating unlimited moisture tolerance. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative sourcing while maintaining functional compatibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LTM-440 are qualified based on the following criteria:

Primary Compatibility Parameters:

• LED Type: Must support T1 or T1 3/4 LED form factors
• Color: Black finish required for visual consistency
• Length Tolerance: Acceptable range 0.433" to 0.453" (11.00mm to 11.50mm) to accommodate PCB layout and component clearance requirements
• Material: Alternative polymeric materials (Nylon 66) acceptable when mechanical and thermal properties remain within application requirements
• Regulatory Compliance: ROHS3 compliance mandatory; REACH status documented

Identified Substitutes:

• 705820110 (Würth Elektronik): 0.433" length, Nylon material
• 705820115 (Würth Elektronik): 0.453" length, Nylon material

Both substitutes maintain T1/T1 3/4 LED compatibility, black color specification, ROHS3 compliance, and equivalent packaging format.

Engineering Selection Recommendations

LTM-440 Selection Criteria:

• Primary choice when Bivar Inc. sourcing is specified or preferred
• Crystalline polymer material selected for specific thermal or mechanical requirements
• MSL 1 rating provides maximum moisture tolerance for extended storage
• Active product status ensures continued manufacturer support and availability

705820110 Selection Criteria:

• Shortest length variant (0.433") suitable for applications requiring minimal PCB standoff height
• Nylon 66 material provides alternative polymer properties with UL94 V-2 flame rating
• Higher inventory availability (5318 Pcs) supports rapid fulfillment
• ROHS3 compliance and REACH unaffected status confirm regulatory alignment
• Active product status from Würth Elektronik ensures supply continuity

705820115 Selection Criteria:

• Longest length variant (0.453") accommodates applications requiring maximum standoff height
• Nylon 66 material with UL94 V-2 rating provides flame-resistant properties
• Adequate inventory (2240 Pcs) supports production requirements
• ROHS3 compliance and REACH unaffected status meet regulatory obligations
• Active product status ensures manufacturer support

Selection Logic: All three parts maintain Active product status and ROHS3 compliance. Length variation (±0.020" tolerance band) accommodates standard PCB design margins. Material substitution from crystalline polymer to Nylon 66 is acceptable when mechanical property requirements remain within application specifications. Würth Elektronik substitutes offer superior inventory availability for supply chain optimization.

Frequently Asked Questions (FAQ)

Q: Can 705820110 and 705820115 be used interchangeably with LTM-440?

A: Both Würth Elektronik parts are functionally compatible within the specified length tolerance band (0.433" to 0.453" vs. 0.440" nominal). Interchangeability depends on PCB layout constraints and component clearance requirements. The 0.007" length difference between 705820110 and LTM-440, and the 0.013" difference between 705820115 and LTM-440, must be evaluated against specific assembly specifications.

Q: What is the material difference between LTM-440 and the Würth Elektronik substitutes?

A: LTM-440 uses crystalline polymer construction, while 705820110 and 705820115 use Nylon 66 (UL94 V-2 rated). Both materials are polymeric and suitable for LED standoff applications. Material selection should be verified against thermal cycling, chemical exposure, and mechanical stress requirements in the target application.

Q: Are all three parts ROHS3 compliant?

A: Yes. LTM-440, 705820110, and 705820115 all carry ROHS3 compliance certification, meeting EU regulatory requirements for restricted substances in electrical and electronic equipment.

Q: What is the difference in moisture sensitivity between these parts?

A: LTM-440 carries MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. The Würth Elektronik substitutes (705820110 and 705820115) list MSL as Not Applicable, indicating these components do not require moisture-controlled storage. Both approaches are compatible with standard component handling practices.

Q: Which part should be selected for supply chain optimization?

A: 705820110 offers the highest inventory availability (5318 Pcs), followed by 705820115 (2240 Pcs). Selection should prioritize length requirements first, then inventory availability for lead time and cost optimization.

Q: Are packaging formats identical across all three parts?

A: Yes. All three parts are supplied in Bag packaging format, suitable for bulk component handling and automated assembly processes.

Q: Can these parts be mixed in a single production run?

A: Length variation across the three parts (0.433" to 0.453") may affect PCB assembly consistency. Mixing should be evaluated against assembly process tolerances and final product specifications. Single-part sourcing per production batch is recommended for dimensional consistency.
