Substitute Part Grouping Explanation

Substitution eligibility for the ELM 5-445 is determined by the following critical parameters:

Primary Substitution Criteria:

• LED Type: T1 configuration
• Material: Black PVC construction
• LED Configuration: 3MM 2-lead mounting
• Manufacturer: Bivar Inc.
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1

Secondary Consideration:

• Length tolerance: Parts within the ELM series with length variations of ±0.010" (0.25mm) from the primary specification maintain functional compatibility in standard mounting applications.

The ELM 4-440 qualifies as a parametric equivalent based on matching LED type, material composition, lead configuration, manufacturer origin, and compliance certifications. The length differential of 0.005" (0.12mm) falls within acceptable mechanical tolerance ranges for this component category.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 5-445 and ELM 4-440 maintain Active product status with full ROHS3 compliance and MSL 1 certification. Selection between these parts is based on specific application length requirements:

ELM 5-445 Selection: Use when application specifications require 0.445" (11.30mm) standoff length. This part is the primary specification for designs engineered to this dimension.

ELM 4-440 Selection: Use as a substitute when 0.440" (11.18mm) length is acceptable within application tolerance. The 0.005" (0.12mm) length reduction maintains compatibility with standard LED mounting footprints and does not affect electrical performance or compliance certifications.

Both parts are manufactured by Bivar Inc. and carry identical compliance ratings, ensuring equivalent reliability and regulatory adherence in production environments.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-440 be used as a direct replacement for ELM 5-445?

A: Yes. The ELM 4-440 functions as a parametric equivalent. Both parts share identical LED type (T1), material (black PVC), lead configuration (3MM 2-lead), and compliance certifications (ROHS3, MSL 1). The length difference of 0.005" (0.12mm) is within acceptable mechanical tolerance for standard LED mounting applications.

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

A: The ELM 5-445 measures 0.445" (11.30mm) while the ELM 4-440 measures 0.440" (11.18mm). This 0.005" (0.12mm) variation affects standoff height in PCB-mounted applications. Verify that your application design accommodates this dimensional change before substitution.

Q: Are both parts ROHS3 compliant?

A: Yes. Both ELM 5-445 and ELM 4-440 are ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity tolerance. No compliance differences exist between these parts.

Q: What does MSL 1 (Unlimited) mean for these components?

A: MSL 1 indicates the lowest moisture sensitivity level. These components require no special moisture control during storage, handling, or assembly. Standard warehouse conditions are sufficient.

Q: Are there inventory considerations when selecting between these parts?

A: Current inventory shows 699 pieces of ELM 5-445 and 991 pieces of ELM 4-440 in stock. Availability may influence substitution decisions in time-sensitive production scenarios.

Q: Do these parts have different electrical characteristics?

A: No. Both parts are mechanical standoffs for T1 LED configurations. Electrical performance is determined by the LED component itself, not the standoff. These parts provide identical mechanical and electrical interface characteristics.
