LTM-140 LED Standoff Equivalent & Substitute Parts

Part Overview

The LTM-140 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., constructed from black crystalline polymer with a 0.140" (3.56mm) length. The part is currently active in production and ROHS3 compliant. Alternative equivalent parts are necessary to support supply chain flexibility, design optimization for material properties, and manufacturing continuity when the primary part faces inventory constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTM-140 is determined by the following critical parameters:

• LED Type Compatibility: Both substitute parts maintain T1 and T1 3/4 LED compatibility
• Length Tolerance: Primary substitute (SLM-140) matches exactly at 0.140" (3.56mm); secondary substitute (705820035) operates within acceptable tolerance at 0.138" (3.50mm), a variance of 0.002"
• Color Match: All parts are black
• RoHS Compliance: All parts maintain ROHS3 compliance status
• Moisture Sensitivity: Primary substitute maintains MSL 1 (Unlimited); secondary substitute shows not applicable
• Material Variation: Substitutes use nylon instead of crystalline polymer, providing alternative mechanical properties within the same functional envelope

Parameter Comparison

Engineering Selection Recommendations

SLM-140 provides a direct parametric equivalent with identical length specifications and same-manufacturer sourcing from Bivar Inc. Both parts carry active product status and maintain ROHS3 compliance with unlimited moisture sensitivity ratings. This substitute is recommended when design specifications do not distinguish between crystalline polymer and nylon material properties.

705820035 from Würth Elektronik satisfies core LED standoff functionality with a minor length variance of 0.002" (0.50mm) within tolerance for most applications. This part features the highest current inventory (5427 Pcs) and nylon construction. Selection of this substitute is appropriate when supply from the primary manufacturer is constrained and the slight length differential is acceptable within your mechanical design envelope. ROHS3 compliance is maintained.

All three parts share identical LED type compatibility, black color specification, and active product status, supporting seamless integration into existing assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SLM-140 be used as a direct drop-in replacement for LTM-140?

A: Yes. SLM-140 matches the LTM-140 in all critical parameters including LED type (T1, T1 3/4), length (0.140"/3.56mm), color (black), and compliance ratings (ROHS3, MSL 1). The only difference is the substitution of nylon material for crystalline polymer. Both parts are manufactured by Bivar Inc. and carry active product status.

Q: What is the impact of using nylon instead of crystalline polymer in SLM-140?

A: The material change from crystalline polymer to nylon affects mechanical properties such as stiffness, thermal characteristics, and chemical resistance. Both materials support the same LED type and physical dimensions. Your design must accommodate nylon's specific mechanical and thermal behavior if material properties are critical to your application.

Q: Is 705820035 compatible with the LTM-140 design?

A: 705820035 is compatible for LED type (T1, T1 3/4), color (black), and compliance requirements (ROHS3). The length difference of 0.002" (0.50mm) between 0.140" and 0.138" must be evaluated within your mechanical tolerance stack-up. This substitute is suitable when this dimensional variance is accommodated by your assembly design.

Q: Why does 705820035 show "Not Applicable" for Moisture Sensitivity Level?

A: Würth Elektronik's 705820035 classification does not assign an MSL rating under the standard moisture sensitivity framework. This does not indicate inadequate moisture protection but reflects different manufacturing and specification documentation standards between manufacturers. ROHS3 compliance is maintained.

Q: What inventory considerations apply to these substitutes?

A: LTM-140 currently stocks 805 Pcs. SLM-140 provides 1994 Pcs availability, and 705820035 offers the highest inventory at 5427 Pcs. Substitute selection may prioritize availability for near-term manufacturing schedules while maintaining all functional and compliance requirements.
