ELM 4-6MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-6MM is an active T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.240" (6.10mm) length. This component is constructed from black PVC material and accommodates 3mm LED configurations with 2-lead connections. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and commercial applications.

Substitute parts are identified when equivalent functional performance can be achieved through alternative designs that maintain compatibility with T1 LED specifications while accommodating minor dimensional or material variations within acceptable engineering tolerances.

Substitute Part Grouping Explanation

Substitute parts for the ELM 4-6MM are qualified based on the following critical parameters that determine functional interchangeability:

Primary Compatibility Criteria:

• LED Type: T1 (maintained across all substitutes)
• LED Size: 3MM (maintained across all substitutes)
• Lead Configuration: 2LD (maintained across all substitutes)
• Mounting Orientation: Vertical (maintained across all substitutes)
• Color: Black (maintained across all substitutes)
• RoHS Compliance: ROHS3 (maintained across all substitutes)
• MSL Rating: 1 (Unlimited) (maintained across all substitutes)
• Product Status: Active (maintained across all substitutes)

Secondary Variation Parameters:

• Length: Tolerance range 0.235" to 0.250" (5.97mm to 6.35mm)
• Material: PVC or Nylon (both acceptable for T1 LED standoff applications)

Substitutes are grouped by their ability to maintain all primary criteria while accommodating minor length variations and material alternatives that do not compromise functional performance in standard mounting applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with ROHS3 compliance and identical MSL ratings, confirming their suitability for equivalent applications. Selection between ELM 4-6MM and its substitutes is determined by specific dimensional and material requirements:

ELM 4-6MM Selection: Choose this part when a 0.240" (6.10mm) length with PVC construction is required. This represents the nominal specification for standard vertical T1 LED standoff applications.

ELM 5-235 Selection: This substitute provides a 0.235" (5.97mm) length with PVC material. The 0.005" (0.13mm) reduction in length accommodates applications requiring slightly reduced standoff height while maintaining identical material properties and all compliance certifications.

H-131C-1-120 Selection: This substitute provides a 0.250" (6.35mm) length with Nylon material. The 0.010" (0.25mm) increase in length and material change to Nylon accommodate applications requiring increased standoff height or enhanced mechanical properties, while maintaining all electrical and compliance specifications.

All substitutes are manufactured by Bivar Inc. and carry identical export classification (EAR99) and tariff codes (3926.90.9985).

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the ELM 4-6MM?

A: Substitutes must maintain T1 LED type, 3MM LED size, 2-lead configuration, vertical mounting orientation, black color, ROHS3 compliance, and MSL 1 rating. Length variations between 0.235" and 0.250" and material alternatives (PVC or Nylon) are acceptable within this product category.

Q: What is the length difference between ELM 4-6MM and its substitutes?

A: ELM 4-6MM measures 0.240" (6.10mm). ELM 5-235 is 0.005" (0.13mm) shorter at 0.235" (5.97mm). H-131C-1-120 is 0.010" (0.25mm) longer at 0.250" (6.35mm). These variations fall within acceptable tolerance ranges for T1 LED standoff applications.

Q: Are there material differences between the substitutes?

A: ELM 4-6MM and ELM 5-235 are both constructed from PVC. H-131C-1-120 uses Nylon material. Both materials are black and maintain identical electrical performance and compliance certifications for T1 LED standoff applications.

Q: Do all substitutes carry the same compliance certifications?

A: Yes. All three parts are ROHS3 compliant, carry MSL 1 (Unlimited) ratings, are classified as EAR99 for export, and share the identical HTSUS tariff code (3926.90.9985).

Q: Can these parts be used interchangeably in existing designs?

A: Interchangeability depends on specific dimensional and material requirements of the application. The 0.015" (0.38mm) total length variation between shortest and longest substitute must be evaluated against PCB layout and mechanical clearance constraints. Material selection (PVC versus Nylon) should be confirmed against environmental and mechanical stress requirements.

Q: What is the inventory status of these parts?

A: ELM 4-6MM has 1,737 pieces in stock. ELM 5-235 has 20,398 pieces in stock. H-131C-1-120 has 1,950 pieces in stock. All are listed as new original inventory.
