ELM 7-590 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 7-590 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.590" (14.99mm) 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 production environments. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative components that maintain functional equivalence within specified electrical and mechanical tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 7-590 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 (3MM LED accommodation)
• Lead Configuration: 2LD (2-lead connection)
• Material: Black PVC
• Mounting Orientation: Vertical
• Manufacturer: Bivar Inc.
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Tolerance Parameter:

• Length: Mechanical height variation within design tolerance

The ELM 4-600 qualifies as a parametric equivalent because it maintains identical specifications across all primary compatibility criteria. The length differential (0.590" versus 0.600") represents a 0.010" (0.25mm) variation, which falls within acceptable mechanical tolerance for LED standoff applications where vertical spacing accommodates minor dimensional differences.

Engineering Selection Recommendations

ELM 7-590 Selection Criteria:

• Primary choice when exact 0.590" (14.99mm) height specification is required
• Active product status ensures ongoing manufacturer support and supply continuity
• ROHS3 compliance and MSL 1 rating support unrestricted storage and handling

ELM 4-600 Selection Criteria:

• Acceptable substitute when 0.010" (0.25mm) additional height accommodates circuit board layout
• Active product status provides equivalent supply reliability
• Identical RoHS3 compliance and MSL 1 rating maintain regulatory and environmental requirements
• Suitable for applications where vertical spacing tolerance permits the dimensional variation

Both parts maintain identical electrical performance, material composition, and regulatory compliance. Selection between ELM 7-590 and ELM 4-600 is determined solely by mechanical height requirements within the specific application circuit board design.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-600 be used as a direct replacement for ELM 7-590?

A: ELM 4-600 is a parametric equivalent substitute. All electrical and material specifications are identical. The 0.010" (0.25mm) length difference must be evaluated against your specific circuit board layout and vertical spacing requirements. If the application accommodates this dimensional variation, substitution is valid.

Q: What is the significance of the length difference between these parts?

A: The ELM 7-590 measures 0.590" (14.99mm) while the ELM 4-600 measures 0.600" (15.24mm). This 0.010" variation affects the vertical standoff height above the circuit board. Applications with fixed height constraints or tight vertical spacing may require the original ELM 7-590 specification.

Q: Are both parts ROHS3 compliant?

A: Yes. Both ELM 7-590 and ELM 4-600 carry ROHS3 compliance certification and MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and regulatory requirements.

Q: What does the "2LD" designation indicate?

A: 2LD specifies a 2-lead configuration, indicating the LED standoff accommodates standard 2-lead LED components. Both substitute parts maintain this identical lead configuration.

Q: Are there inventory or lead time considerations between these parts?

A: Current inventory shows ELM 7-590 at 1130 pieces and ELM 4-600 at 1058 pieces. Both parts maintain Active product status with Bivar Inc., indicating ongoing availability. Specific lead time and allocation information should be obtained from your component supplier.

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

A: Interchangeability depends on mechanical tolerance in your specific design. If your circuit board layout accommodates the 0.010" height difference, parts are interchangeable. If height is a critical constraint, the original ELM 7-590 specification must be maintained.
