NTM-180 LED Standoff Equivalent & Substitute Parts

Part Overview

The NTM-180 is an active LED standoff manufactured by Bivar Inc., designed for T1 and T1 3/4 LED applications. This component is a vertical mount nylon standoff with a 0.180" (4.57mm) length and black color specification. The part is ROHS3 compliant and carries an MSL rating of 1 (Unlimited), indicating minimal moisture sensitivity. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NTM-180 is determined by the following critical parameters:

Primary Substitution Criteria:

• LED Type: T1 or T1 3/4 compatibility
• Material: Nylon construction
• Color: Black
• Mounting Style: Vertical orientation
• Length Tolerance: Dimensional compatibility within acceptable mechanical tolerances
• Compliance: ROHS3 compliance and EAR99 ECCN classification

The substitute part 705820045 (Würth Elektronik) meets these criteria with a length specification of 0.177" (4.50mm), which falls within the acceptable tolerance range for T1/T1 3/4 LED standoff applications. Both parts share identical material composition (Nylon), color specification (Black), LED type support, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the NTM-180 and 705820045 are active products with ROHS3 compliance and identical ECCN/HTSUS classifications, confirming regulatory equivalence for industrial and commercial applications. The dimensional difference of 0.003" (0.07mm) between the two parts represents a 1.5% variance in length, which is within standard mechanical tolerances for LED standoff applications in this category.

Selection between these parts should be based on:

1. Availability and Lead Time: Current inventory status and procurement timelines
2. Supplier Relationship: Existing vendor agreements and supply chain preferences
3. Cost Considerations: Unit pricing and volume discounts
4. Application-Specific Requirements: PCB layout constraints and mechanical clearance specifications

Both parts are suitable for direct substitution in T1 and T1 3/4 LED mounting applications where vertical orientation and black nylon construction are specified.

Frequently Asked Questions (FAQ)

Q: Can the 705820045 be used as a direct replacement for the NTM-180?

A: Yes. Both parts support T1 and T1 3/4 LED types, feature black nylon construction, vertical mounting orientation, and ROHS3 compliance. The 0.003" length difference is within acceptable mechanical tolerances for this product category.

Q: What is the significance of the length difference between 0.180" and 0.177"?

A: The 0.003" (0.07mm) variance represents standard manufacturing tolerance in nylon standoff production. This difference does not affect functional compatibility in T1/T1 3/4 LED applications where standoff height is not a critical design parameter.

Q: Are both parts suitable for moisture-sensitive environments?

A: The NTM-180 carries an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. The 705820045 lists MSL as Not Applicable, confirming equivalent or superior moisture resistance characteristics. Both parts are suitable for standard industrial and commercial environments.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, carry EAR99 ECCN classification, and share the identical HTSUS code (3926.90.9985), confirming regulatory equivalence for export and domestic applications.

Q: What is the difference between Nylon and Nylon 66 material specifications?

A: Nylon 66 is a specific formulation of polyamide nylon with enhanced thermal and mechanical properties. For LED standoff applications, Nylon 66 provides equivalent or superior performance compared to general nylon specifications while maintaining compatibility with T1/T1 3/4 LED mounting requirements.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided that PCB layout and mechanical clearance specifications accommodate the 0.003" length variance. No design modifications are required for standard T1/T1 3/4 LED standoff applications.
