SLM-570 LED Standoff Equivalent & Substitute Parts

Part Overview

The SLM-570 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., constructed from black nylon with a length of 0.570" (14.48mm). 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 original inventory is unavailable, when supply chain constraints occur, or when design flexibility permits dimensional tolerance within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLM-570 are qualified based on the following criteria:

Critical Parameters (Must Match):

• LED Type: T1 and T1 3/4 compatibility required
• Material: Nylon construction required
• Color: Black finish required
• RoHS Compliance: ROHS3 compliant status required

High-Tolerance Parameters (Allowable Variation):

• Length: Dimensional tolerance of ±0.021" (±0.52mm) from the nominal 0.570" (14.48mm) is permissible within standard mechanical assembly tolerances

All identified substitute parts are manufactured by Würth Elektronik and meet the critical parameter requirements. The three qualified substitutes (705820140, 705820145, 705820150) vary in length specification while maintaining compatibility with T1/T1 3/4 LED types and nylon material composition.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original SLM-570 specification. Selection among the three Würth Elektronik alternatives should be based on mechanical assembly requirements and available board space:

705820145 provides the closest dimensional match to the SLM-570, with a length of 0.571" (14.50mm) versus the original 0.570" (14.48mm), representing a variance of +0.001" (+0.02mm).

705820140 offers a shorter profile at 0.551" (14.00mm), suitable for applications with reduced vertical clearance requirements.

705820150 provides an extended length of 0.591" (15.00mm), applicable where increased standoff height is required.

All three alternatives are manufactured from nylon with black coloring and support T1/T1 3/4 LED types, maintaining functional equivalence with the original component.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 705820145 directly replace the Bivar SLM-570 in existing assemblies?

A: Yes. The 705820145 meets all critical parameters: T1/T1 3/4 LED compatibility, nylon material, black color, and ROHS3 compliance. The length variance of +0.001" (0.02mm) is within standard mechanical tolerances for LED standoff applications.

Q: What is the maximum allowable length variation when substituting LED standoffs?

A: Based on the provided substitute parts, length variations of ±0.021" (±0.52mm) from the nominal dimension are permissible. This range encompasses all three qualified alternatives (0.551" to 0.591") relative to the original 0.570" specification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The SLM-570 and all three Würth Elektronik substitutes (705820140, 705820145, 705820150) carry ROHS3 compliance certification.

Q: Do the Würth Elektronik parts require different handling or storage procedures compared to the Bivar SLM-570?

A: Both manufacturers' nylon LED standoffs are classified with Moisture Sensitivity Level 1 (SLM-570) or Not Applicable (Würth Elektronik parts). Standard component storage practices apply to all parts in this group.

Q: Which substitute part should be selected for space-constrained PCB designs?

A: The 705820140 at 0.551" (14.00mm) provides the shortest profile. For designs requiring minimal vertical clearance, this part offers the most compact standoff height while maintaining all functional and compliance requirements.

Q: Can multiple substitute parts be used within the same assembly?

A: All three Würth Elektronik substitutes are functionally equivalent and maintain identical LED type, material, and color specifications. Assembly design should account for the length variations when multiple standoff heights are used in the same circuit board layout.
