Key Parameters

Substitute Part Grouping Explanation

The ELM 3-285 is classified as a parametric equivalent to the ELM 3-280 based on the following substitution criteria:

• LED Type Compatibility: Both components use identical T1 3/4 LED specifications
• Material Consistency: Both are manufactured from black PVC
• Series Compatibility: Both belong to the ELM 3 series
• Regulatory Compliance: Both maintain ROHS3 compliance and MSL 1 rating
• Dimensional Tolerance: The length difference of 0.005" (0.13mm) between 0.280" and 0.285" falls within standard mechanical tolerance ranges for LED standoff applications
• Manufacturing Status: Both parts are produced by Bivar Inc. and maintain Active product status

These parameters establish the basis for substitution in applications where the minimal height variance is acceptable within assembly design constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 3-280 and ELM 3-285 are Active products from Bivar Inc. with equivalent ROHS3 compliance and MSL 1 ratings. The selection between these parts depends on mechanical height requirements for the specific LED assembly application. The ELM 3-280 provides a nominal height of 0.280" (7.11mm), while the ELM 3-285 provides 0.285" (7.24mm). Design documentation should specify which height variant meets assembly clearance and optical alignment specifications. Both parts are suitable for use in applications where either height specification is acceptable.

Frequently Asked Questions (FAQ)

Q: Can ELM 3-285 be used as a direct replacement for ELM 3-280?

A: The ELM 3-285 can be substituted for the ELM 3-280 where the application design accommodates the 0.005" (0.13mm) increase in height. Both parts share identical LED type, material, and regulatory compliance specifications. Verify that this dimensional difference does not affect optical alignment, clearance requirements, or mechanical fit within your assembly.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by LED type (T1 3/4), material (black PVC), series (ELM 3), regulatory compliance (ROHS3), and MSL rating (1). The length parameter permits substitution when the 0.005" dimensional variance is acceptable within design tolerance.

Q: Are both parts RoHS compliant?

A: Yes, both the ELM 3-280 and ELM 3-285 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard storage and handling conditions.

Q: What is the packaging format for these parts?

A: Both parts are supplied in bag packaging format as standard OEM distribution.

Q: Does the length difference affect mechanical compatibility?

A: The 0.005" (0.13mm) length difference is within standard mechanical tolerance ranges for LED standoff applications. Confirm compatibility based on your specific PCB layout, LED seating requirements, and optical alignment specifications before implementation.
