ELM 4-620 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-620 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.620" (15.75mm) 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 specific application geometries necessitate alternative standoff heights within the same product series.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the ELM 4 series is determined by the following critical parameters:

Invariant Parameters (Must Match):

• Manufacturer: Bivar Inc.
• Series: ELM 4
• LED Type: T1
• Material: Black PVC
• Lead Configuration: 2LD
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameter (Allows Substitution):

• Length: Standoff height measured in inches and millimeters

The ELM 4-600 qualifies as a parametric equivalent because it maintains all invariant parameters while differing only in physical length. This length variation (0.600" versus 0.620") accommodates different PCB-to-LED vertical spacing requirements within the same mechanical and electrical framework.

Parameter Comparison

Engineering Selection Recommendations

Both ELM 4-620 and ELM 4-600 maintain Active product status and full ROHS3 compliance. Selection between these parts is determined by the required standoff height for your specific PCB assembly geometry. The 0.020" (0.51mm) length differential between parts must be evaluated against your vertical spacing constraints. Both parts carry identical Moisture Sensitivity Level 1 classification, indicating no special storage or handling requirements. Packaging format is identical (Bag) for both variants, supporting equivalent supply chain integration.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-600 be used as a direct replacement for ELM 4-620?

A: ELM 4-600 is a parametric equivalent within the ELM 4 series but differs in physical length by 0.020" (0.51mm). Substitution is valid only when your application accommodates the shorter 0.600" standoff height. Verify PCB-to-LED vertical spacing requirements before selection.

Q: What parameters must remain constant for substitution within the ELM 4 series?

A: Manufacturer (Bivar Inc.), LED type (T1), material (black PVC), lead configuration (2LD), RoHS compliance (ROHS3), and Moisture Sensitivity Level (1) must all remain unchanged. Only standoff length varies among qualified substitutes.

Q: Are there any compliance or certification differences between ELM 4-620 and ELM 4-600?

A: No. Both parts carry identical ROHS3 compliance, Moisture Sensitivity Level 1, and Active product status. Regulatory and environmental classifications are equivalent.

Q: How does the 0.020" length difference affect component selection?

A: The length differential directly impacts vertical spacing between the PCB surface and the LED emitter. Your circuit design must accommodate the specific standoff height. Measure your required vertical clearance and select the corresponding part number accordingly.

Q: Are packaging and inventory considerations the same for both parts?

A: Both parts are supplied in Bag packaging format. Inventory levels differ (ELM 4-620: 755 Pcs; ELM 4-600: 1058 Pcs), which may influence lead time and availability for your procurement timeline.
