LTM-670 LED Standoff Equivalent & Substitute Parts

Part Overview

The LTM-670 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., constructed from black crystalline polymer with a length of 0.670" (17.02mm). This product is actively manufactured and ROHS3 compliant. Alternative component models become necessary due to supply availability, regional inventory constraints, or specific manufacturing requirements while maintaining electrical and mechanical compatibility within the defined parameter tolerance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LTM-670 is permissible with components maintaining the following criteria:

• LED Type: T1 or T1 3/4 configuration (mechanical compatibility with standard LED leads)
• Length Tolerance: 0.669" to 0.670" (17.00mm to 17.02mm) for mounting height consistency
• Color: Black finish
• Material: Polymer-based construction (crystalline polymer or nylon acceptable within dimensional constraints)
• Regulatory Compliance: ROHS3 compliant minimum
• Packaging Format: Bag packaging

The substitute part 705820170 meets these parameters with nylon material substitution, which maintains mechanical and environmental compliance while providing functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the LTM-670 and 705820170 are actively manufactured components with ROHS3 compliance. The dimensional tolerance of 0.01" (0.02mm) length differential is within acceptable mechanical variation for LED standoff applications. The material difference between crystalline polymer and nylon 66 does not affect functional compatibility given both materials provide adequate structural support for T1/T1 3/4 LED packages and comply with stated regulatory requirements. Selection between these parts is determined by supply availability and manufacturing qualification status rather than performance differentiation.

Frequently Asked Questions (FAQ)

Q: Are the LTM-670 and 705820170 directly interchangeable in PCB designs?

A: Yes, both components maintain T1/T1 3/4 LED compatibility and length specifications within 0.01" tolerance, permitting direct substitution in PCB layouts and BOMs without dimensional modifications.

Q: Does the material change from crystalline polymer to nylon 66 affect performance?

A: No. Both materials provide equivalent mechanical support for LED standoff applications. Material selection is a manufacturing choice that does not impact functional performance in standard LED mounting configurations.

Q: What is the significance of the MSL rating difference?

A: The LTM-670 MSL Level 1 indicates unlimited moisture exposure tolerance. The 705820170 lists MSL as Not Applicable, reflecting Würth Elektronik's classification for nylon materials. Both components are suitable for standard soldering and assembly processes without moisture-control restrictions.

Q: Are there inventory or packaging considerations for substitution?

A: Both components are supplied in bag packaging format. Current inventory availability (933 units for LTM-670, 2714 units for 705820170) may influence procurement decisions, but packaging format and storage requirements remain equivalent.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the LTM-670 and 705820170 are ROHS3 compliant and classified under identical HTSUS and ECCN codes (3926.90.9985 and EAR99 respectively), confirming equivalent regulatory standing for international commerce and environmental compliance.
