ELM 3-425 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 3-425 is a T1 3/4 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.425" (10.80mm) length. This component is designed for vertical mounting applications requiring precise standoff height specifications. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production environments. Substitute parts become necessary when specific inventory availability constraints exist or when application tolerances permit alternative standoff heights within the same product family.

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 3-425 is determined by the following critical parameters:

Primary Substitution Criteria:

• LED Type: T1 3/4 (must match exactly)
• Material: Black PVC (must match exactly)
• Color: Black (must match exactly)
• RoHS Status: ROHS3 Compliant (must match exactly)
• Moisture Sensitivity Level: 1 (Unlimited) (must match exactly)

Secondary Consideration:

• Length tolerance: Substitute parts must fall within the mechanical envelope requirements of the application. The ELM 3-425 specifies 0.425" (10.80mm); substitute parts with lengths of 0.430" (10.92mm) or 0.440" (11.18mm) represent dimensional variations within the same product family.

The identified substitutes—ELM 1-11MM and ELM 3-440—share all primary parameters with the main part. Both maintain T1 3/4 LED compatibility, black PVC construction, ROHS3 compliance, and MSL 1 rating. Length variations are the only dimensional difference and must be evaluated against specific application requirements.

Engineering Selection Recommendations

ELM 3-425 Primary Selection: The ELM 3-425 remains the specified part for applications requiring the exact 0.425" (10.80mm) standoff height. All compliance certifications and product status indicators confirm suitability for current production use.

ELM 1-11MM Substitution: The ELM 1-11MM provides a substitute option with a 0.430" (10.92mm) length, representing a 0.005" (0.12mm) increase from the primary part. This substitute maintains identical LED type, material composition, color, and all compliance ratings. Selection of this substitute requires confirmation that the application mechanical envelope accommodates the increased height.

ELM 3-440 Substitution: The ELM 3-440 provides a substitute option with a 0.440" (11.18mm) length, representing a 0.015" (0.38mm) increase from the primary part. This substitute maintains identical LED type, material composition, color, and all compliance ratings. Selection of this substitute requires confirmation that the application mechanical envelope accommodates the increased height. The ELM 3-440 shares the same base product number (ELM3-4) as the primary part, indicating closer design family alignment.

All three parts maintain Active product status and ROHS3 compliance, ensuring availability and regulatory conformance for production applications.

Frequently Asked Questions (FAQ)

Q: What determines whether ELM 1-11MM or ELM 3-440 can substitute for ELM 3-425?

A: Substitution is determined by application tolerance for standoff height variation. The ELM 3-425 specifies 0.425" (10.80mm). The ELM 1-11MM increases this by 0.005" (0.12mm) to 0.430" (10.92mm), while the ELM 3-440 increases it by 0.015" (0.38mm) to 0.440" (11.18mm). All other parameters—LED type (T1 3/4), material (black PVC), color, RoHS compliance, and MSL rating—remain identical. The application design must accommodate these height differences.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts maintain identical RoHS3 compliance status and Moisture Sensitivity Level 1 (Unlimited) rating. All are packaged in bags and manufactured by Bivar Inc. Compliance certifications present no barriers to substitution.

Q: What is the inventory availability difference?

A: The ELM 3-425 has 727 pieces in stock, the ELM 1-11MM has 1475 pieces, and the ELM 3-440 has 22638 pieces. Inventory levels may influence substitution decisions when supply constraints exist.

Q: Can I use ELM 3-440 if my application requires the exact 0.425" height?

A: No. The ELM 3-440 length of 0.440" (11.18mm) exceeds the specified 0.425" (10.80mm) by 0.015" (0.38mm). Substitution is only valid when application design tolerances explicitly permit the increased standoff height.

Q: Are the series designations (ELM 3 vs. ELM 1) significant for substitution?

A: Series designation reflects product family organization. The ELM 3-425 and ELM 3-440 share the same base product number (ELM3-4) and series, while the ELM 1-11MM belongs to the ELM 1 series. Despite series differences, all three parts meet the identical electrical and mechanical substitution criteria for T1 3/4 LED standoff applications.
