ELM 4-390 Equivalent & Substitute Parts

Part Overview

The ELM 4-390 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.390" (9.91mm) length. The component features a black PVC construction and accommodates 3MM LED packages with 2-lead configurations. This part is Active in product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in applications where the core functional requirements remain constant.

Substitute Part Grouping Explanation

Substitute parts for the ELM 4-390 are classified based on strict alignment with the following critical parameters:

Primary Substitution Criteria:

• LED Type: T1 (mandatory match)
• Lead Configuration: 2-Lead (mandatory match)
• Color: Black (mandatory match)
• RoHS Compliance: ROHS3 Compliant (mandatory match)
• MSL Rating: 1 (Unlimited) (mandatory match)

Secondary Substitution Criteria:

• Length tolerance: Variations within 0.010" (0.254mm) of 0.390" are acceptable for mechanical fit
• Material: PVC or equivalent polymer (Nylon acceptable within dimensional constraints)
• Manufacturer: Bivar Inc. (consistent quality and certification standards)

The ELM 5-390 qualifies as a parametric equivalent with identical specifications across all critical parameters. The H-201C qualifies as a substitute with compatible T1 LED accommodation, 2-lead configuration, and black color, with a minor length variation of 0.010" (0.254mm) and material substitution from PVC to Nylon.

Parameter Comparison

Engineering Selection Recommendations

ELM 5-390 Selection Criteria: The ELM 5-390 is a direct parametric equivalent to the ELM 4-390. All electrical, mechanical, and compliance specifications are identical. Selection between these parts is determined by inventory availability and supply chain considerations. Both parts maintain Active product status and ROHS3 compliance. The ELM 5-390 offers higher inventory availability (2242 Pcs versus 963 Pcs).

H-201C Selection Criteria: The H-201C is a compatible substitute with equivalent T1 LED accommodation and 2-lead configuration. The material composition differs (Nylon versus PVC), and the length specification is 0.010" (0.254mm) shorter at 0.380" (9.65mm). This substitute is suitable for applications where the reduced standoff height is acceptable within PCB assembly tolerances. The H-201C maintains ROHS3 compliance and MSL 1 rating. Significantly higher inventory availability (63104 Pcs) supports supply chain flexibility.

All three parts are manufactured by Bivar Inc., ensuring consistent quality standards and certification compliance across the substitution group.

Frequently Asked Questions (FAQ)

Q: Can the ELM 5-390 directly replace the ELM 4-390 in all applications?

A: Yes. The ELM 5-390 is a parametric equivalent with identical specifications for LED type (T1), length (0.390"), color (Black), material (PVC), lead configuration (2-lead), and all compliance ratings (ROHS3, MSL 1). Direct substitution is supported without design modification.

Q: What is the primary difference between the H-201C and the ELM 4-390?

A: The H-201C differs in two parameters: material composition (Nylon versus PVC) and length (0.380" versus 0.390"). The 0.010" length reduction must be evaluated against PCB assembly height requirements. All other specifications, including LED type (T1), color (Black), lead configuration (2-lead), and compliance ratings, are equivalent.

Q: Is the H-201C suitable for applications requiring exact 0.390" standoff height?

A: No. The H-201C length specification is 0.380" (9.65mm), which is 0.010" shorter than the ELM 4-390. Applications with strict height tolerances require the ELM 4-390 or ELM 5-390. The H-201C is suitable only when the reduced height is compatible with PCB design specifications.

Q: Are all three parts RoHS compliant?

A: Yes. The ELM 4-390, ELM 5-390, and H-201C are all ROHS3 compliant. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating, supporting standard storage and handling protocols.

Q: Which substitute part offers the best inventory availability?

A: The H-201C offers the highest inventory availability at 63104 Pcs. The ELM 5-390 provides 2242 Pcs, and the ELM 4-390 provides 963 Pcs. Inventory selection should be balanced against mechanical compatibility requirements, particularly the 0.010" length difference in the H-201C.

Q: Can material substitution from PVC to Nylon affect performance?

A: Material substitution from PVC to Nylon does not affect electrical performance or LED accommodation. Both materials are black, support T1 LED mounting, and maintain equivalent compliance ratings. Material selection should be evaluated based on mechanical durability requirements and environmental exposure conditions specific to the application.
