Key Parameters

Substitute Part Grouping Explanation

Substitutes for the SLM-420 are qualified based on the following parameters: LED type compatibility (T1, T1 3/4), material composition (Nylon), color (Black), and mechanical dimensions (length). The substitute parts from Würth Elektronik—705820105 and 705820110—maintain the same LED type and material specifications. Length variations are within acceptable mechanical tolerances for LED standoff applications.

The two qualifying substitute parts are:

• 705820105: Length 0.413" (10.50mm), variation of –0.007" from main part
• 705820110: Length 0.433" (11.00mm), variation of +0.013" from main part

Parameter Comparison

Engineering Selection Recommendations

All three parts—SLM-420, 705820105, and 705820110—maintain active product status and ROHS3 compliance, confirming their eligibility for current designs. The Würth Elektronik substitutes are certified alternatives that preserve the critical functional parameters: LED type (T1, T1 3/4), material (Nylon), and color (Black).

For applications where exact dimensional matching is required, the SLM-420 remains the specified part. The 705820105 offers a compact alternative with 0.007" less height, suitable for space-constrained layouts. The 705820110 provides 0.013" additional height, applicable to designs requiring extended standoff spacing. Each substitute maintains mechanical and electrical properties consistent with the original specification.

Frequently Asked Questions (FAQ)

Q: Can 705820105 or 705820110 be used as direct replacements for SLM-420? A: Both Würth Elektronik parts are parametric equivalents sharing identical LED type (T1, T1 3/4), material (Nylon), and color (Black). Selection depends on dimensional requirements. The 705820105 is shorter by 0.007"; the 705820110 is taller by 0.013".

Q: What determines substitutability between these LED standoffs? A: Substitution is based on LED type compatibility, material composition, color, and mechanical dimensions. All three parts meet these criteria and maintain active product status and ROHS3 compliance.

Q: Are there compliance differences between the main part and substitutes? A: All parts comply with ROHS3 regulations. Both Würth Elektronik substitutes also maintain REACH unaffected status and carry the same ECCN classification (EAR99), ensuring regulatory consistency.

Q: How do packaging and inventory considerations apply? A: The SLM-420 is available in bag packaging with 686 pieces in stock. The 705820105 offers 2,331 pieces, and the 705820110 offers 5,318 pieces in bag packaging, providing alternative sourcing options.
