Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for LED standoffs is determined by the following parameters:

• LED Type Compatibility: T1 and T1 3/4 LED form factors must match
• Length Tolerance: Standoff height variations within 0.030" (0.76mm) are functionally equivalent for most PCB applications
• Material Class: Nylon-based polymers and crystalline polymers with equivalent flame ratings are interchangeable
• Color: Black finish is consistent across all substitutes
• Compliance: RoHS3 compliance and REACH unaffected status required

Based on these criteria, two substitute parts are identified:

705820150 (Würth Elektronik): Differs only in length (0.591" vs 0.610"), maintaining all other specifications.

LTM-620 (Bivar Inc.): Functionally equivalent with crystalline polymer material and length of 0.620", within acceptable tolerance range.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and full RoHS3 compliance with REACH unaffected designation. Selection between 705820155 and its substitutes should be based on:

705820155: Primary choice when exact 0.610" (15.50mm) height is specified in PCB design. Würth Elektronik sourcing preferred for supply chain consistency.

705820150: Suitable when 0.591" (15.00mm) height is acceptable. Maintains identical material and flame rating specifications. Lower inventory availability (1,325 units) compared to main part.

LTM-620: Applicable when 0.620" (15.75mm) height accommodates design requirements. Crystalline polymer material provides equivalent mechanical and thermal properties. Highest inventory availability (5,359 units) supports extended production runs.

Frequently Asked Questions (FAQ)

Q: Can 705820150 be used as a direct replacement for 705820155?

A: Yes, within design tolerance. The 0.019" (0.50mm) length difference is functionally equivalent for standard PCB applications. Verify that PCB design accommodates the shorter standoff height.

Q: What is the material difference between 705820155 and LTM-620?

A: 705820155 uses Nylon 66 while LTM-620 uses Crystalline Polymer. Both materials meet UL94 V-2 flame rating and provide equivalent mechanical support for T1/T1 3/4 LED leads.

Q: Are all three parts RoHS3 compliant?

A: Yes. All parts carry ROHS3 Compliant status and REACH Unaffected designation, meeting current environmental and regulatory requirements.

Q: Which substitute offers the best inventory availability?

A: LTM-620 (Bivar Inc.) has the highest stock level at 5,359 units, followed by 705820155 at 2,358 units, and 705820150 at 1,325 units.

Q: Does LED type compatibility differ between substitutes?

A: No. All three parts support T1 and T1 3/4 LED form factors identically.

Q: What is the maximum acceptable length variation for substitution?

A: Length variations up to 0.030" (0.76mm) are within functional tolerance for LED standoff applications. All three parts fall within this range.
