NTM-700 LED Standoff Equivalent & Substitute Parts

Part Overview

The NTM-700 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.700" (17.78mm) length. This component is constructed from black nylon material and is classified as an active product with ROHS3 compliance. LED standoffs serve as mechanical spacers and alignment fixtures in electronic assemblies, positioning light-emitting diodes at precise heights and angles relative to circuit boards and enclosures. Substitute parts become necessary when original inventory is unavailable, when supply chain optimization is required, or when design flexibility permits selection from qualified alternative manufacturers meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NTM-700 is determined by strict adherence to the following parameters:

Primary Compatibility Criteria:

• LED Type: T1 or T1 3/4 configuration
• Material: Nylon construction
• Color: Black
• Packaging: Bag format
• RoHS Compliance: ROHS3 Compliant
• HTSUS Classification: 3926.90.9985

Secondary Consideration:

• Length tolerance: Substitute parts must accommodate the mechanical mounting requirements of the application. The NTM-700 specifies 0.700" (17.78mm). Substitute parts with lengths of 0.669" (17.00mm) and 0.709" (18.00mm) represent minor dimensional variations within typical manufacturing tolerances for LED standoff applications.

The two identified substitute parts (705820170 and 705820180) from Würth Elektronik meet all primary compatibility criteria and differ only in length specification, representing parametric equivalents suitable for applications where dimensional flexibility exists within the assembly design.

Parameter Comparison

Engineering Selection Recommendations

NTM-700 (Bivar Inc.): Select this part when the exact 0.700" (17.78mm) length specification is required by the assembly design. This part maintains active product status and full ROHS3 compliance. Bivar Inc. is the original manufacturer specification.

705820170 (Würth Elektronik): This substitute provides a 0.669" (17.00mm) length, representing a 0.031" (0.78mm) reduction from the NTM-700 specification. Select this part when the assembly design permits a shorter standoff height and when Würth Elektronik supply chain availability is advantageous. This part is active, ROHS3 compliant, and REACH unaffected.

705820180 (Würth Elektronik): This substitute provides a 0.709" (18.00mm) length, representing a 0.009" (0.22mm) increase from the NTM-700 specification. Select this part when the assembly design permits a slightly taller standoff height and when Würth Elektronik supply chain availability is advantageous. This part is active, ROHS3 compliant, and REACH unaffected.

All three parts share identical LED type compatibility, material composition (nylon), color specification (black), regulatory compliance status, and trade classification. Selection between these parts depends solely on the mechanical length requirement of the specific application assembly.

Frequently Asked Questions (FAQ)

Q: Can 705820170 or 705820180 be used as direct replacements for NTM-700 in all applications?

A: No. While these parts are parametric equivalents meeting all electrical and material specifications, they differ in length. 705820170 is 0.031" shorter and 705820180 is 0.009" taller than the NTM-700. Substitution is valid only when the assembly design accommodates these dimensional variations without affecting LED positioning, circuit board clearance, or enclosure fit.

Q: What is the significance of the Nylon 66 specification in the Würth Elektronik parts?

A: Nylon 66 is a specific formulation of nylon material with defined mechanical and thermal properties. The NTM-700 specification lists "Nylon" without material grade designation. Nylon 66 is a standard engineering-grade nylon commonly used in LED standoff applications and is compatible with the general nylon specification of the NTM-700.

Q: Are all three parts ROHS3 compliant?

A: Yes. The NTM-700, 705820170, and 705820180 are all ROHS3 compliant, confirming restriction of hazardous substances in accordance with applicable regulations.

Q: What does "REACH Unaffected" mean for the Würth Elektronik parts?

A: REACH Unaffected indicates that the part does not contain substances of very high concern (SVHC) listed under the REACH regulation, or that the part is exempt from REACH requirements. This status confirms regulatory compliance for European supply chain applications.

Q: Can these parts be intermixed in the same assembly?

A: Intermixing is not recommended in standard applications. LED standoff height consistency across an assembly typically affects visual alignment and mechanical stability. If multiple standoffs are used in a single assembly, maintain uniform height specification. Select either NTM-700, 705820170, or 705820180 for the complete assembly requirement.

Q: What is the Moisture Sensitivity Level (MSL) significance?

A: The NTM-700 specifies MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. The Würth Elektronik parts list MSL as "Not Applicable," confirming these components also have no moisture sensitivity constraints. Both specifications are equivalent for practical application purposes.

Q: Are there any performance differences between these parts?

A: No performance differences exist. These parts are mechanical spacers with no active electrical function. Differences are limited to physical dimensions (length) and material grade designation (Nylon 66 vs. Nylon). Functional performance in LED positioning and mechanical support is equivalent across all three parts when length requirements are met.
