SLM-510 Equivalent & Substitute Parts Reference

Part Overview

The SLM-510 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black nylon construction with a 0.510" (12.95mm) length and is classified as Active product status. The SLM-510 is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Equivalent and substitute parts are identified based on matching LED form factor, color, material compatibility, and dimensional tolerance ranges that permit direct functional replacement in standard LED mounting applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLM-510 are qualified based on the following criteria:

Primary Matching Parameters:

• LED form factor: T1 or T1 3/4 compatibility
• Color: Black
• Mounting orientation: Vertical (SR VERT)
• RoHS compliance: ROHS3 Compliant

Dimensional Tolerance Range: Substitute parts must accommodate LED standoff lengths within the functional range of 0.492" to 0.531" (12.50mm to 13.50mm). This range permits mechanical interchangeability in standard PCB mounting applications where minor height variations do not affect circuit performance.

Material Compatibility: Substitutes may use either Nylon or Crystalline Polymer materials, both of which provide equivalent mechanical and thermal properties for LED standoff applications.

Compliance Requirements: All substitute parts maintain ROHS3 compliance and are classified as Active product status, ensuring continued availability and regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

Bivar Inc. Substitutes: The LTM-520 represents a direct functional equivalent manufactured by the same supplier. While the material differs (Crystalline Polymer vs. Nylon), both materials meet ROHS3 compliance requirements. The LTM-520 length of 0.520" (13.21mm) falls within the acceptable dimensional tolerance range and maintains Active product status with equivalent MSL rating.

Würth Elektronik Substitutes: The 705820125, 705820130, and 705820135 series provide cross-manufacturer alternatives with nylon construction matching the SLM-510 material specification. All three parts maintain ROHS3 compliance and Active product status. Length variations (0.492", 0.512", and 0.531" respectively) accommodate standard PCB design tolerances for LED standoff applications.

Compliance Basis: All substitute parts carry ROHS3 Compliant certification and Active product status, confirming regulatory alignment and ongoing manufacturing support. Selection among substitutes should be based on dimensional requirements specific to the target PCB design and available inventory.

Frequently Asked Questions (FAQ)

Q: Can the LTM-520 replace the SLM-510 despite the material difference? A: Yes. Both Nylon and Crystalline Polymer materials provide equivalent mechanical properties for LED standoff applications. The LTM-520 maintains ROHS3 compliance and Active status, with length within the functional tolerance range.

Q: What is the acceptable length variation range for substitution? A: Substitute parts range from 0.492" to 0.531" (12.50mm to 13.50mm), representing a tolerance band of approximately ±0.020" around the nominal SLM-510 length of 0.510". This range accommodates standard PCB mounting clearances.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 Compliant certification, ensuring regulatory alignment with the original SLM-510 specification.

Q: Can I mix different substitute parts in the same assembly? A: Yes. All substitute parts meet identical functional and compliance criteria. Mixed usage is permissible where design tolerances accommodate the dimensional variations listed in the parameter comparison table.

Q: What is the difference between Bivar Inc. and Würth Elektronik substitutes? A: Bivar Inc. (LTM-520) is the original manufacturer's alternative product. Würth Elektronik parts (705820125, 705820130, 705820135) are cross-manufacturer equivalents. Both categories meet all specified compliance and functional requirements.

Q: How do I select between the three Würth Elektronik options? A: Selection depends on PCB design requirements. The 705820125 (0.492") provides minimum height, 705820130 (0.512") offers closest dimensional match to SLM-510, and 705820135 (0.531") provides maximum height within the tolerance range.
