ELM 4-455 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-455 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.455" (11.56mm) 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 tolerance flexibility necessitate alternative components within the ELM 4 series.

Substitute Part Grouping Explanation

Substitution within the ELM 4-455 product line is determined by the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Bivar Inc.
• Series: ELM 4
• LED Type: T1
• Material: Black PVC
• Configuration: Vertical Mount, 3MM, 2-Lead
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1

Variable Parameter:

• Length: 0.455" (11.56mm) for primary part; 0.440" (11.18mm) for substitute

The ELM 4-440 substitute part maintains identical electrical and mechanical specifications across all core parameters. The length differential of 0.015" (0.38mm) represents a dimensional tolerance variation within the ELM 4 series design envelope. Both parts share the same base product number (ELM4-4), confirming their functional equivalence within the standoff category.

Parameter Comparison

Engineering Selection Recommendations

Both ELM 4-455 and ELM 4-440 maintain Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Selection between these parts is determined by dimensional requirements specific to the application mounting environment.

The ELM 4-455 provides 0.455" (11.56mm) standoff height, suitable for applications requiring maximum vertical clearance. The ELM 4-440 provides 0.440" (11.18mm) standoff height, appropriate for space-constrained designs where the 0.015" (0.38mm) reduction accommodates tighter PCB-to-component spacing.

Both parts are manufactured from identical black PVC material and support T1 LED configurations with 2-lead connections. Inventory availability should be evaluated against project timeline requirements, as current stock levels differ between variants.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-440 directly replace ELM 4-455 in existing designs?

A: Direct replacement is possible only if the application design tolerates a 0.015" (0.38mm) reduction in standoff height. The ELM 4-440 maintains all electrical and material specifications of the ELM 4-455. Design verification is required to confirm that reduced vertical clearance does not impact component-to-component spacing or thermal management.

Q: Are there electrical differences between ELM 4-455 and ELM 4-440?

A: No electrical differences exist. Both parts are T1 LED standoffs with identical 2-lead configurations, material composition, and compliance certifications. The only difference is physical length.

Q: What is the significance of the 0.015" length difference?

A: The length difference represents a dimensional tolerance variation within the ELM 4 series design. This variation is critical only in applications where precise vertical spacing between the LED and adjacent components is specified. Applications with flexible height tolerances are unaffected by this difference.

Q: Are both parts ROHS3 compliant?

A: Yes. Both ELM 4-455 and ELM 4-440 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard manufacturing and storage environments.

Q: What packaging format is used for both parts?

A: Both parts are supplied in Bag packaging format, consistent with standard component distribution for standoff products.
