ELM 4-250 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-250 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.250" (6.35mm) length. This component is constructed from black PVC material and accommodates 3mm LED configurations with 2-lead connections. The part maintains Active product status and is RoHS3 compliant, making it suitable for current electronic assembly requirements.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in applications where the primary component is unavailable or when alternative material compositions are acceptable within design constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-250 is determined by the following critical parameters:

Primary Substitution Criteria:

• LED Type: T1
• LED Configuration: 3MM 2LD
• Color: Black
• RoHS Compliance: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Secondary Compatibility Factors:

• Length tolerance within 0.240" to 0.250" (6.10mm to 6.35mm)
• Material composition (PVC or Nylon acceptable for mechanical standoff function)
• Mounting orientation: Vertical

The identified substitutes maintain compatibility across all primary criteria. Variations in material composition (PVC versus Nylon) and minor length differences (0.010" variance) remain within acceptable mechanical tolerances for LED standoff applications.

Engineering Selection Recommendations

ELM 4-250 (Primary Component) The ELM 4-250 remains the preferred selection when PVC material composition is specified in design documentation. Active product status and full inventory availability support immediate procurement. RoHS3 compliance and MSL 1 rating confirm suitability for standard manufacturing environments without moisture sensitivity constraints.

ELM 4-6MM (Parametric Equivalent) The ELM 4-6MM serves as a direct substitute when a 0.010" length reduction (from 0.250" to 0.240") is acceptable within mechanical assembly tolerances. PVC material composition matches the primary part. Active status and higher inventory levels (1737 units) provide supply continuity. This substitute is appropriate for applications where vertical standoff height permits minor dimensional variance.

H-131C-1-120 (Material Variant Substitute) The H-131C-1-120 provides substitution capability when Nylon material composition is acceptable as an alternative to PVC. Length specification matches the primary part exactly at 0.250" (6.35mm). Nylon construction offers different mechanical properties while maintaining identical electrical and compliance characteristics. Active status and robust inventory (1950 units) support availability. This substitute is suitable for applications where material flexibility exists in design specifications.

All three parts maintain Active product status, RoHS3 compliance, and MSL 1 ratings, confirming interchangeability within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the ELM 4-250? A: Substitution eligibility requires matching LED Type (T1), LED Configuration (3MM 2LD), Color (Black), RoHS compliance (ROHS3), and MSL rating (1). Length tolerance of ±0.010" and material composition variations (PVC or Nylon) are acceptable within mechanical standoff function parameters.

Q: Can the ELM 4-6MM replace the ELM 4-250 in all applications? A: The ELM 4-6MM is substitutable when the 0.010" shorter length (0.240" versus 0.250") does not conflict with mechanical assembly requirements or PCB clearance specifications. Both parts share identical PVC material composition and electrical characteristics.

Q: What is the difference between PVC and Nylon material options? A: Both PVC (ELM 4-250, ELM 4-6MM) and Nylon (H-131C-1-120) materials function identically as mechanical LED standoffs. Material selection depends on design specifications regarding thermal properties, chemical resistance, or mechanical durability requirements. All three parts maintain equivalent electrical performance and compliance certifications.

Q: Are all three parts currently available? A: Yes. ELM 4-250 has 1105 units in stock, ELM 4-6MM has 1737 units, and H-131C-1-120 has 1950 units available as new original inventory.

Q: Do these parts require different handling or storage procedures? A: No. All three parts share identical MSL 1 (Unlimited) ratings, indicating no moisture sensitivity constraints. Standard component storage and handling procedures apply uniformly across all substitutes.

Q: Can length differences affect PCB assembly compatibility? A: The ELM 4-6MM's 0.010" shorter length may impact applications with tight vertical clearance specifications. Verify PCB design documentation and mechanical assembly drawings before substituting with the shorter variant. The H-131C-1-120 maintains identical length to the primary part.
