NTM-370 LED Standoff Equivalent & Substitute Parts

Part Overview

The NTM-370 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.370" (9.40mm) 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 are identified when equivalent functional performance can be achieved through alternative manufacturers while maintaining compatibility with the specified LED form factor, material composition, and mechanical dimensions within acceptable tolerance ranges.

Key Parameters

Parameter	Value	Significance for Substitution
LED Type	T1, T1 3/4	Determines mechanical compatibility with LED package
Material	Nylon	Defines electrical insulation and thermal properties
Color	Black	Optical and aesthetic specification
Length	0.370" (9.40mm)	Critical dimension for vertical spacing in assembly
Product Status	Active	Ensures ongoing availability and support
RoHS Compliance	ROHS3 Compliant	Regulatory requirement for hazardous substance restriction
Packaging	Bag	Bulk handling and storage format

Substitute Part Grouping Explanation

Substitute parts for the NTM-370 are qualified based on the following criteria:

Primary Compatibility Requirements:

LED form factor: T1 or T1 3/4 (mechanical fit with standard LED packages)
Material: Nylon (electrical insulation and dimensional stability)
Color: Black (visual and aesthetic consistency)
Length tolerance: Within ±0.020" of the nominal 0.370" specification
Product status: Active (current production and availability)
Regulatory compliance: ROHS3 Compliant (hazardous substance restrictions)

Substitution Logic: The identified substitute parts (705820090 and 705820095) from Würth Elektronik maintain all primary compatibility requirements. Both parts are manufactured from nylon material in black color and support T1/T1 3/4 LED packages. Length variations of ±0.004" to ±0.004" from the nominal specification fall within acceptable mechanical tolerance for vertical standoff applications where precise spacing is required but minor dimensional variations do not compromise functional performance.

Engineering Selection Recommendations

NTM-370 (Bivar Inc.): Select this part when the original design specification requires the exact 0.370" (9.40mm) length dimension and when Bivar Inc. supply chain continuity is prioritized. This part maintains active product status with ROHS3 compliance and MSL Level 1 rating.

705820090 (Würth Elektronik): This substitute provides a 0.354" (9.00mm) length, representing a 0.016" reduction from the nominal specification. Select this part when the assembly design accommodates a shorter standoff height or when Würth Elektronik supply availability is preferred. ROHS3 compliance and REACH Unaffected status are confirmed.

705820095 (Würth Elektronik): This substitute provides a 0.374" (9.50mm) length, representing a 0.004" increase from the nominal specification. Select this part when the assembly design accommodates a slightly taller standoff height or when Würth Elektronik supply availability is preferred. ROHS3 compliance and REACH Unaffected status are confirmed.

All three parts share identical LED form factor compatibility, nylon material composition, black color, and regulatory compliance status. Selection between these options depends on specific assembly height requirements and supplier availability.

Frequently Asked Questions (FAQ)

Q: Can 705820090 be used as a direct replacement for NTM-370?

A: 705820090 is functionally equivalent for T1/T1 3/4 LED standoff applications but has a 0.016" shorter length (0.354" versus 0.370"). Direct substitution is possible only if the assembly design tolerates this dimensional reduction without compromising LED positioning or clearance requirements.

Q: What is the length tolerance difference between the three parts?

A: NTM-370 specifies 0.370" (9.40mm), 705820090 specifies 0.354" (9.00mm), and 705820095 specifies 0.374" (9.50mm). The total dimensional range across all three parts spans 0.020", which may be significant in space-constrained assemblies.

Q: Are all three parts RoHS compliant?

A: Yes. NTM-370, 705820090, and 705820095 are all ROHS3 Compliant, meeting hazardous substance restriction requirements for electronic component manufacturing.

Q: What material differences exist between the parts?

A: NTM-370 is specified as nylon, while 705820090 and 705820095 are specified as nylon 66 with UL94 V-2 rating. Nylon 66 is a specific engineering grade of nylon with defined thermal and mechanical properties. Both materials are functionally equivalent for LED standoff applications.

Q: Can these parts be interchanged in existing assemblies?

A: Interchangeability depends on the specific assembly design. All three parts support T1/T1 3/4 LED packages and are constructed from nylon in black color. However, the length variations (0.016" to 0.004") must be evaluated against the mechanical constraints of the target assembly to ensure proper LED positioning and clearance.

Q: What is the inventory status for each part?

A: NTM-370 has 822 pieces in stock, 705820090 has 4259 pieces in stock, and 705820095 has 1578 pieces in stock. Availability may influence selection when supply continuity is a consideration.
