Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 3-220 are determined by equivalence in the following critical parameters:

• LED Type: T1 3/4 (physical form factor)
• Length: 0.220" (5.59mm) (mechanical dimension)
• Material: Black PVC (construction material)
• Color: Black (visual specification)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental stability)

The ELM 1-220 meets all these criteria and is classified as a parametric equivalent. Both parts share identical LED type, length, material, color, and compliance specifications. The primary distinction lies in the mounting mechanism—the ELM 3-220 features a screw-retained design, while the ELM 1-220 incorporates a self-retaining mechanism. This functional difference does not alter the core electrical or mechanical compatibility requirements for LED standoff applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 3-220 and ELM 1-220 are active products from Bivar Inc., meeting ROHS3 compliance requirements with identical MSL ratings of 1 (Unlimited). Selection between these parts depends exclusively on the mechanical mounting requirements of the application:

• ELM 3-220: Select when screw-retained mounting is required or preferred for secure positioning.
• ELM 1-220: Select when self-retaining mechanism is acceptable or advantageous for simplified assembly.

Current inventory levels support either selection, with 1139 units of ELM 3-220 and 1594 units of ELM 1-220 available.

Frequently Asked Questions (FAQ)

Q: Can ELM 1-220 directly replace ELM 3-220? A: Yes, the ELM 1-220 is a parametric equivalent with identical electrical and mechanical specifications (LED type, length, material, color, compliance). The functional difference is the mounting mechanism—self-retaining versus screw-retained. Compatibility depends on whether your PCB or assembly design accommodates the self-retaining feature.

Q: Are there differences in regulatory compliance between these parts? A: No. Both parts are ROHS3 compliant with MSL ratings of 1 (Unlimited), meeting identical environmental and regulatory requirements.

Q: Do these parts have the same dimensions? A: Yes. Both ELM 3-220 and ELM 1-220 are specified as T1 3/4 LED standoffs with 0.220" (5.59mm) length in black PVC.

Q: What is the key mechanical difference between these substitutes? A: The ELM 3-220 uses a screw-retained mounting mechanism, while the ELM 1-220 incorporates a self-retaining design. The choice between them depends on your assembly process and PCB mounting requirements.

Q: Are packaging quantities the same? A: Both parts are supplied in bag packaging. Current inventory shows 1139 units of ELM 3-220 and 1594 units of ELM 1-220 available.
