ELM 5-8MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 5-8MM is an active T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.310" (7.87mm) length. This black PVC component serves as a mechanical support and alignment fixture for T1 LED packages in electronic assemblies. Substitute parts are identified when equivalent functional performance can be achieved through alternative Bivar Inc. standoff models that maintain compatibility with T1 LED packages while meeting the same regulatory and environmental requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 5-8MM are qualified based on the following criteria:

Primary Compatibility Parameters:

• LED Type: T1 (identical package accommodation)
• Material: Black PVC (identical chemical and thermal properties)
• Mounting Orientation: Vertical (SR VERT configuration)
• RoHS Status: ROHS3 Compliant (regulatory equivalence)
• Moisture Sensitivity Level: 1 (Unlimited) (identical environmental tolerance)
• Product Status: Active (current manufacturing status)

Secondary Variation Parameter:

• Length: Tolerance range of ±0.005" to ±0.010" from nominal 0.310" (7.87mm)

The three identified substitutes (ELM 2-315, ELM 2-320, and ELM 4-315) maintain all primary compatibility parameters while operating within acceptable length variations. These length variations (0.315" and 0.320") represent minor dimensional differences that do not compromise T1 LED package accommodation or vertical mounting functionality.

Parameter Comparison

Engineering Selection Recommendations

ELM 2-315 Substitution: The ELM 2-315 operates as a direct functional equivalent with a length of 0.315" (8.00mm), representing a +0.005" variance from the ELM 5-8MM. This part maintains all primary compatibility parameters and holds active product status with ROHS3 compliance. Inventory availability is 7,562 units.

ELM 2-320 Substitution: The ELM 2-320 functions as an equivalent with a length of 0.320" (8.13mm), representing a +0.010" variance from the ELM 5-8MM. This part satisfies all primary compatibility requirements and maintains active product status with ROHS3 compliance. Inventory availability is 26,182 units, the highest among all substitutes.

ELM 4-315 Substitution: The ELM 4-315 operates as a functional equivalent with a length of 0.315" (8.00mm), matching the ELM 2-315 dimensional specification. This part maintains all primary compatibility parameters and holds active product status with ROHS3 compliance. Inventory availability is 4,972 units.

All three substitutes are manufactured by Bivar Inc., ensuring consistent quality standards and design specifications. Selection among substitutes should be based on specific application clearance requirements and available inventory levels.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the ELM 5-8MM?

A: Substitution eligibility is determined by matching the following parameters: T1 LED type accommodation, black PVC material composition, vertical mounting orientation, ROHS3 compliance status, and MSL 1 rating. Length variations within ±0.010" are acceptable for functional equivalence.

Q: Are the substitute parts manufactured by the same company?

A: Yes. All substitute parts (ELM 2-315, ELM 2-320, and ELM 4-315) are manufactured by Bivar Inc., the same manufacturer as the ELM 5-8MM.

Q: What is the length difference between the main part and substitutes?

A: The ELM 5-8MM has a length of 0.310" (7.87mm). The ELM 2-315 and ELM 4-315 are 0.315" (8.00mm), a +0.005" difference. The ELM 2-320 is 0.320" (8.13mm), a +0.010" difference.

Q: Do all parts have the same regulatory compliance?

A: Yes. The ELM 5-8MM and all three substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the packaging format for these parts?

A: All parts, including the main part and substitutes, are supplied in bag packaging.

Q: Are there differences in inventory availability?

A: Yes. Current inventory levels are: ELM 5-8MM (676 units), ELM 2-315 (7,562 units), ELM 2-320 (26,182 units), and ELM 4-315 (4,972 units).

Q: Can length variations affect assembly compatibility?

A: Length variations of ±0.010" are within acceptable tolerance for T1 LED standoff applications. Specific application clearance requirements should be evaluated based on PCB layout and component spacing constraints.

Q: Are all substitute parts currently in active production?

A: Yes. All substitute parts maintain active product status, ensuring continued availability and manufacturing support.
