NTM-140 Equivalent & Substitute Parts

Part Overview

The NTM-140 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.140" (3.56mm) length specification. This black nylon component is classified as Active product status and maintains ROHS3 compliance. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NTM-140 are qualified based on the following critical parameters:

• LED Type Compatibility: T1 and T1 3/4 LED form factors
• Length Tolerance: 0.140" (3.56mm) nominal dimension with allowable mechanical variance
• Material Composition: Black nylon construction
• Mounting Configuration: Vertical orientation capability
• Regulatory Compliance: ROHS3 certification requirement

The identified substitutes maintain these core parameters, ensuring mechanical and functional compatibility within the original application envelope.

Parameter Comparison

Engineering Selection Recommendations

SLM-140 (Bivar Inc.) provides direct parametric equivalence to the NTM-140. Both components share identical length specifications (0.140"/3.56mm), material composition (nylon), color (black), and regulatory compliance (ROHS3). Both maintain MSL 1 rating and Active product status. This substitute is suitable for direct replacement in applications requiring identical mechanical and environmental characteristics.

705820035 (Würth Elektronik) qualifies as a substitute with minor dimensional variance. The length specification of 0.138" (3.50mm) represents a 0.002" (0.06mm) reduction from the NTM-140 nominal dimension. The material specification includes UL94 V-2 flame rating classification. This component maintains ROHS3 compliance and Active product status. The dimensional tolerance must be evaluated against application-specific mechanical constraints.

All three components maintain Active product status and ROHS3 compliance, supporting long-term availability and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can SLM-140 replace NTM-140 in all applications?

A: SLM-140 maintains identical specifications for LED type (T1/T1 3/4), length (0.140"/3.56mm), material (nylon), color (black), and regulatory compliance (ROHS3). Both components are manufactured by Bivar Inc. and carry Active product status. Direct substitution is supported by parametric equivalence.

Q: What is the significance of the 0.002" length difference between NTM-140 and 705820035?

A: The NTM-140 specifies 0.140" (3.56mm) length, while 705820035 specifies 0.138" (3.50mm) length. This 0.002" (0.06mm) dimensional variance must be evaluated against application-specific mechanical tolerances, PCB layout constraints, and clearance requirements. Both components support T1/T1 3/4 LED types and maintain ROHS3 compliance.

Q: Are all three parts available in the same packaging format?

A: All three components are supplied in Bag packaging format, supporting standard component handling and storage procedures.

Q: What does ROHS3 compliance indicate?

A: ROHS3 compliance certifies that the component meets Restriction of Hazardous Substances Directive requirements, restricting specified hazardous materials in electrical and electronic equipment. All three parts maintain this certification.

Q: Does moisture sensitivity affect component selection?

A: NTM-140 and SLM-140 both carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. 705820035 carries Not Applicable MSL designation. For applications with controlled environmental conditions, all three components are suitable. For high-humidity or moisture-exposure environments, NTM-140 and SLM-140 provide explicit unlimited moisture tolerance.
