LTM-330 LED Standoff Equivalent & Substitute Parts

Part Overview

The LTM-330 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., constructed from crystalline polymer material with a 0.330" (8.38mm) 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 while maintaining functional compatibility within the defined parameter range.

Key Parameters

Parameter	Value	Specification Notes
LED Type	T1, T1 3/4	Determines mechanical fit and optical alignment
Length	0.330" (8.38mm)	Critical for PCB standoff height and component clearance
Color	Black	Visual identification and light blocking properties
Material	Crystalline Polymer	Mechanical strength and thermal stability
RoHS Status	ROHS3 Compliant	Regulatory compliance requirement
Packaging	Bag	Bulk component packaging format
HTSUS Code	3926.90.9985	Tariff classification for plastic articles

Substitute Part Grouping Explanation

Substitute parts for the LTM-330 are qualified based on the following critical parameters that must align with the main part specification:

Mandatory Matching Parameters:

LED Type: T1, T1 3/4 (mechanical compatibility with LED leads)
Color: Black (visual and functional consistency)
RoHS3 Compliance: Required for regulatory alignment
HTSUS Classification: 3926.90.9985 (product category consistency)

Allowable Variation Parameters:

Length: ±0.020" tolerance range (0.310" to 0.350") accommodates minor dimensional variations while maintaining functional standoff height
Material: Alternative polymer formulations (Nylon 66 vs. Crystalline Polymer) acceptable when mechanical properties remain equivalent

The substitute parts listed (705820080 and 705820085) meet all mandatory parameters and fall within the allowable length variation range, qualifying them as parametric equivalents for the LTM-330.

Engineering Selection Recommendations

705820080 (Würth Elektronik) - Shorter Length Variant: This substitute features a 0.315" (8.00mm) length, representing a 0.015" reduction from the LTM-330 specification. Selection is appropriate when reduced standoff height is acceptable within the assembly design. Material composition (Nylon 66 vs. Crystalline Polymer) maintains equivalent mechanical performance. RoHS3 compliance and Active product status ensure regulatory and supply continuity.

705820085 (Würth Elektronik) - Longer Length Variant: This substitute features a 0.335" (8.50mm) length, representing a 0.005" increase from the LTM-330 specification. Selection is appropriate when increased standoff height is required or when the minimal dimensional variance is within assembly tolerances. Material composition (Nylon 66 vs. Crystalline Polymer) maintains equivalent mechanical performance. RoHS3 compliance and Active product status ensure regulatory and supply continuity.

Selection Basis: All three parts maintain Active product status, RoHS3 compliance, and identical HTSUS classification. The choice between LTM-330 and its substitutes depends solely on the specific standoff height requirement within the target assembly. Both Würth Elektronik alternatives provide equivalent functional performance with documented inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 705820080 or 705820085 be used interchangeably with LTM-330 in all applications?

A: Substitution is valid only when the specific length requirement of the target assembly accommodates the dimensional variance. The 705820080 (0.315") is 0.015" shorter; the 705820085 (0.335") is 0.005" longer than the LTM-330 (0.330"). Verify PCB clearance and component spacing before substitution.

Q: What is the significance of the material difference between Crystalline Polymer and Nylon 66?

A: Both materials are thermoplastic polymers suitable for LED standoff applications. Nylon 66 (used in Würth Elektronik parts) and Crystalline Polymer (used in LTM-330) provide equivalent mechanical strength and thermal stability for this product category. Material selection does not affect functional compatibility.

Q: Are all three parts RoHS3 compliant?

A: Yes. The LTM-330, 705820080, and 705820085 are all RoHS3 compliant, ensuring compatibility with current regulatory requirements and production standards.

Q: What does the HTSUS code 3926.90.9985 indicate?

A: This code classifies all three parts as plastic articles not otherwise specified, confirming they belong to the same product category for tariff and regulatory purposes.

Q: How should I select between the two Würth Elektronik substitutes?

A: Selection depends on the required standoff height for your specific assembly. Use 705820080 (0.315") when reduced height is acceptable; use 705820085 (0.335") when increased height is required or when minimal variance from the original 0.330" specification is preferred.

Q: Is inventory availability a factor in substitute selection?

A: Inventory levels are provided for reference: LTM-330 (863 Pcs), 705820080 (17,403 Pcs), and 705820085 (1,971 Pcs). Availability should be evaluated against project timelines and volume requirements.
