SLM-470 LED Standoff Equivalent & Substitute Parts

Part Overview

The SLM-470 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 0.470" (11.94mm) length and is classified as an active product with ROHS3 compliance. LED standoffs serve as mechanical and electrical positioning elements in circuit board assemblies, and equivalent substitutes may be required due to inventory availability, supply chain considerations, or design flexibility across compatible mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLM-470 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 or T1 3/4 form factor
• Material: Nylon construction
• Color: Black
• Mounting Orientation: Vertical standoff configuration
• RoHS Compliance: ROHS3 Compliant status

Secondary Tolerance Parameter:

• Length: Mechanical length variation within acceptable assembly tolerances

The three identified substitute parts (705820115, 705820120, 705820125) manufactured by Würth Elektronik satisfy all primary criteria. Length variations range from 0.453" (11.50mm) to 0.492" (12.50mm), representing mechanical tolerances around the nominal SLM-470 dimension of 0.470" (11.94mm). These variations fall within standard mechanical compatibility ranges for LED standoff applications where precise height matching is not a critical design constraint.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory and supply chain continuity. Selection among the SLM-470 and its equivalents should be based on the following factors:

SLM-470 (Bivar Inc.): Select when the nominal 0.470" (11.94mm) length is specified in the design documentation and inventory availability permits.

705820120 (Würth Elektronik): This substitute provides the closest dimensional match at 0.472" (12.00mm), representing a +0.002" (0.06mm) variance from the SLM-470. This part is suitable for designs with mechanical tolerance specifications that accommodate this minimal deviation.

705820115 (Würth Elektronik): This substitute measures 0.453" (11.50mm), representing a -0.017" (0.44mm) variance. Selection is appropriate for applications where reduced standoff height is acceptable within the circuit board assembly design.

705820125 (Würth Elektronik): This substitute measures 0.492" (12.50mm), representing a +0.022" (0.56mm) variance. Selection is appropriate for applications where increased standoff height is acceptable within the circuit board assembly design.

All substitutes are manufactured from Nylon 66 with UL94 V-2 flame rating, maintaining material performance characteristics consistent with the SLM-470 nylon construction.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the SLM-470?

A: Substitution eligibility requires matching LED type (T1/T1 3/4), material (nylon), color (black), mounting orientation (vertical), and RoHS compliance status. Length variations within the specified range are acceptable based on mechanical tolerance allowances in the assembly design.

Q: Are the Würth Elektronik parts direct mechanical replacements?

A: The Würth parts are mechanically compatible within standard tolerance ranges. The 705820120 provides the closest dimensional match at 0.472" (12.00mm). The 705820115 and 705820125 offer alternative heights of 0.453" and 0.492" respectively, suitable for designs accommodating these variations.

Q: Do all substitute parts meet the same compliance requirements?

A: All identified substitutes maintain ROHS3 compliance and active product status. The Würth parts include UL94 V-2 flame rating certification and REACH Unaffected status, providing equivalent regulatory standing to the SLM-470.

Q: What is the significance of the length variations?

A: Length variations reflect mechanical tolerance specifications inherent to LED standoff manufacturing. The range from 0.453" to 0.492" accommodates different circuit board assembly requirements where precise standoff height may vary based on LED component specifications and PCB layout constraints.

Q: Can I use these parts interchangeably in existing designs?

A: Interchangeability depends on the mechanical tolerance specifications documented in the original design. Designs specifying the SLM-470 at 0.470" (11.94mm) should verify that the selected substitute length falls within the acceptable tolerance band for the application before implementation.

Q: What packaging format is used for these parts?

A: All parts, including the SLM-470 and all three Würth substitutes, are supplied in bag packaging, maintaining consistent handling and storage requirements across the product group.
