MLM1-177 LED Standoff Equivalent & Substitute Parts

Part Overview

The MLM1-177 is an active T1/T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.177" (4.50mm) height. This component is constructed from black nylon material and is ROHS3 compliant. Equivalent substitute parts are identified based on matching electrical and mechanical parameters, including LED form factor, standoff height, material composition, and regulatory compliance status. Substitute parts enable procurement flexibility, inventory optimization, and supply chain continuity when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MLM1-177 are qualified based on strict parameter matching across the following criteria:

Critical Matching Parameters:

• LED form factor (T1, T1 3/4)
• Standoff height (0.177" / 4.50mm)
• Material composition (Nylon)
• Color (Black)
• RoHS3 compliance status

Supporting Compliance Parameters:

• ECCN classification (EAR99)
• HTSUS tariff code (3926.90.9985)
• Active product status

The substitute part 705820045 from Würth Elektronik meets all critical mechanical and electrical parameters, ensuring direct functional equivalence in vertical LED mounting applications. Both parts share identical dimensional specifications, material properties, and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the MLM1-177 and 705820045 are active products with full ROHS3 compliance and identical mechanical specifications. Selection between these parts should be based on:

Availability and Lead Time: The 705820045 substitute maintains higher inventory levels (6850 pcs) compared to the MLM1-177 (777 pcs), providing improved procurement reliability.

Regulatory Compliance: Both parts satisfy EAR99 export classification and HTSUS tariff requirements. The 705820045 carries explicit REACH Unaffected status, providing additional regulatory documentation for supply chain compliance.

Material Specification: The 705820045 specifies Nylon 66 with UL94 V-2 flame rating, providing enhanced material traceability and flammability certification compared to the general nylon specification of the MLM1-177.

Moisture Handling: The MLM1-177 specifies MSL 1 (Unlimited), indicating no moisture sensitivity requirements. The 705820045 lists MSL as Not Applicable, which is consistent with passive mechanical components and does not impact functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 705820045 be used as a direct replacement for the MLM1-177 in vertical LED mounting applications?

A: Yes. Both parts share identical LED form factors (T1, T1 3/4), standoff heights (0.177" / 4.50mm), material composition (Nylon), and color (Black). They are mechanically and functionally equivalent for vertical mounting applications.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant and classified as EAR99 for export purposes. The 705820045 provides explicit REACH Unaffected documentation. No compliance barriers exist for substitution.

Q: What is the significance of the UL94 V-2 rating on the 705820045?

A: UL94 V-2 is a flame rating for nylon materials indicating vertical burning classification. This provides additional material certification documentation for the 705820045 compared to the MLM1-177, but does not alter functional equivalence for LED standoff applications.

Q: Does the difference in Moisture Sensitivity Level affect substitution?

A: No. The MLM1-177 specifies MSL 1 (Unlimited), indicating no moisture sensitivity. The 705820045 lists MSL as Not Applicable, which is appropriate for passive mechanical components. This difference does not impact functional performance or substitution suitability.

Q: Are packaging specifications identical?

A: Both parts are supplied in bag packaging. Packaging quantities may differ based on supplier inventory practices, but packaging format is equivalent.

Q: What inventory considerations should guide part selection?

A: The 705820045 maintains significantly higher stock levels (6850 pcs) compared to the MLM1-177 (777 pcs), supporting improved procurement lead times and supply chain continuity for high-volume applications.
