Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 705820145 is determined by the following parameters:

Primary Substitution Criteria:

• LED type compatibility (T1, T1 3/4)
• Material composition (Nylon 66)
• Flame rating (UL94 V-2)
• Color (Black)
• Regulatory compliance (ROHS3, REACH Unaffected)

Variable Parameter:

• Length (mechanical height): Substitutes are available in 0.551" (14.00mm), 0.571" (14.50mm), and 0.591" (15.00mm) configurations

The 705820145 can be substituted with 705820140 or 705820150 based on application-specific height requirements. All three parts maintain identical material, flame rating, LED compatibility, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts (705820145, 705820140, 705820150) are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts is determined solely by mechanical height requirements for the specific application:

• 705820140 (0.551" / 14.00mm): Shortest configuration, suitable for compact PCB layouts with minimal vertical clearance
• 705820145 (0.571" / 14.50mm): Standard mid-range height
• 705820150 (0.591" / 15.00mm): Tallest configuration, suitable for applications requiring maximum standoff height

All parts maintain identical electrical and material properties, regulatory compliance, and LED type compatibility. Selection should be based on available PCB space and mechanical assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can 705820140, 705820145, and 705820150 be used interchangeably?

A: These parts are mechanically interchangeable only if the application tolerates the height differences (0.551", 0.571", and 0.591" respectively). All three maintain identical material, flame rating, LED compatibility, and compliance certifications. Height selection depends on available vertical space in the assembly.

Q: What is the significance of the UL94 V-2 flame rating?

A: UL94 V-2 indicates the material meets UL94 flammability standards at the V-2 level, demonstrating controlled burning characteristics. This rating is consistent across all three substitute parts.

Q: Are these parts RoHS compliant?

A: Yes, all three parts (705820145, 705820140, 705820150) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What LED types are compatible with these standoffs?

A: These standoffs are designed for T1 and T1 3/4 LED packages. This compatibility is maintained across all three substitute parts.

Q: Does packaging differ between substitute parts?

A: No, all three parts are supplied in bag packaging with identical handling and storage requirements.
