SLM-490 LED Standoff Equivalent & Substitute Parts

Part Overview

The SLM-490 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., constructed from black nylon with a length of 0.490" (12.45mm). This component is classified as an active product and is ROHS3 compliant. LED standoffs serve as mechanical supports and alignment fixtures for light-emitting diodes in electronic assemblies. Substitute parts are identified when equivalent functional performance can be achieved through alternative manufacturers while maintaining critical dimensional and material specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLM-490 are qualified based on the following criteria:

Critical Parameters for Substitution:

• LED Type: T1 or T1 3/4 compatibility
• Material: Nylon construction
• Color: Black
• RoHS Compliance: ROHS3 Compliant
• Product Status: Active

The three identified substitute parts are manufactured by Würth Elektronik and maintain identical LED type, material, and color specifications. Dimensional variation in length is within acceptable tolerance ranges for mechanical standoff applications. All substitute parts maintain ROHS3 compliance and active product status.

Parameter Comparison

Engineering Selection Recommendations

All three Würth Elektronik substitute parts maintain active product status and ROHS3 compliance, meeting regulatory requirements equivalent to the SLM-490. Selection among substitute parts should be based on dimensional requirements specific to the application:

705820120: Length 0.472" (12.00mm) — shortest option, 0.018" shorter than SLM-490 705820125: Length 0.492" (12.50mm) — closest dimensional match, 0.002" longer than SLM-490 705820130: Length 0.512" (13.00mm) — longest option, 0.022" longer than SLM-490

The Würth Elektronik parts specify Nylon 66 with UL94 V-2 rating, indicating enhanced material specification compared to the base SLM-490 designation. All substitute parts are available in active inventory status.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the SLM-490? A: Substitute parts must maintain T1/T1 3/4 LED type compatibility, black nylon construction, ROHS3 compliance, and active product status. Dimensional length variation is acceptable within the specified tolerance range.

Q: How do the Würth Elektronik parts differ from the Bivar SLM-490? A: The primary difference is manufacturer and length specification. Würth parts specify Nylon 66 material with UL94 V-2 flame rating. Length variations range from 0.472" to 0.512", compared to the SLM-490 at 0.490".

Q: Which substitute part has the closest dimensional match? A: Part 705820125 at 0.492" (12.50mm) provides the closest dimensional match to the SLM-490 at 0.490" (12.45mm), with a difference of 0.002".

Q: Are all substitute parts ROHS3 compliant? A: Yes, all three Würth Elektronik substitute parts are ROHS3 compliant and maintain active product status.

Q: What is the packaging format for these parts? A: All parts, including the SLM-490 and substitute options, are supplied in bag packaging.

Q: Do the substitute parts have different moisture sensitivity requirements? A: The Würth Elektronik parts list Moisture Sensitivity Level as Not Applicable, compared to the SLM-490 at MSL 1 (Unlimited). This indicates the substitute parts do not require moisture-controlled storage.
