NTM-190 LED Standoff Equivalent & Substitute Parts

Part Overview

The NTM-190 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.190" (4.83mm) 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 printed circuit boards. Substitute parts become necessary when original inventory is unavailable, when supply chain optimization is required, or when design flexibility permits equivalent mechanical and electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NTM-190 is determined by strict adherence to the following parameters:

Critical Parameters (Must Match Exactly):

• LED Type: T1 or T1 3/4 form factor
• Material: Nylon construction
• Color: Black
• RoHS Status: ROHS3 Compliant

Allowable Variance Parameters:

• Length: Tolerance of ±0.010" (0.25mm) from 0.190" nominal is acceptable for mechanical fit in standard PCB mounting holes and LED socket applications
• Moisture Sensitivity Level: Equivalent or lower MSL rating acceptable

The substitute part 705820050 (Würth Elektronik) qualifies as a parametric equivalent because it maintains identical LED type, material composition, and color specification, with length variance of 0.007" (0.17mm) within acceptable mechanical tolerance for T1/T1 3/4 LED standoff applications.

Parameter Comparison

Engineering Selection Recommendations

NTM-190 (Bivar Inc.): Select this part when Bivar Inc. inventory is available and supply continuity with the original manufacturer is prioritized. This part carries Moisture Sensitivity Level 1 classification, indicating no moisture-related storage restrictions.

705820050 (Würth Elektronik): This substitute is suitable for applications where Würth Elektronik supply chain access is preferred or when higher inventory availability is required. The 0.007" length variance (0.197" vs. 0.190") remains within standard mechanical tolerances for T1/T1 3/4 LED standoff mounting. Both parts maintain ROHS3 compliance and are classified as active products in current production.

Selection between these parts should be based on procurement availability, supply chain strategy, and inventory management requirements rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can the 705820050 be used as a direct replacement for the NTM-190 in existing designs?

A: Yes. Both parts share identical LED type (T1/T1 3/4), material (nylon), color (black), and RoHS compliance status. The length difference of 0.007" (0.17mm) falls within standard mechanical tolerances for LED standoff applications and does not affect form factor compatibility with T1/T1 3/4 LED packages or standard PCB mounting holes.

Q: What is the significance of the length tolerance between these parts?

A: LED standoff length determines the vertical spacing between the LED package and the PCB surface. The 0.190" and 0.197" specifications represent nominal dimensions with standard manufacturing tolerances. This 0.007" variance is typical within the LED standoff component category and does not compromise mechanical fit or optical alignment in standard applications.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant and carry active product status. The NTM-190 specifies Moisture Sensitivity Level 1 (unlimited storage), while the 705820050 lists MSL as Not Applicable. This indicates the Würth Elektronik part has no moisture sensitivity restrictions, representing equivalent or superior handling characteristics.

Q: What packaging format is used for both parts?

A: Both the NTM-190 and 705820050 are supplied in bag packaging, suitable for standard component storage and automated assembly processes.

Q: Are there any material specification differences between Nylon and Nylon 66?

A: Nylon 66 is a specific formulation of polyamide 66 resin, representing a standard engineering-grade nylon material. The NTM-190 specifies "Nylon" while the 705820050 specifies "Nylon 66." Nylon 66 is a common base material for LED standoff applications and is compatible with the general nylon specification for this component category.
