ELM 1-425 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 1-425 is a T1 3/4 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.425" (10.80mm) vertical height. This component is classified as an active product and serves as a mechanical mounting solution for LED applications requiring precise standoff positioning.

Substitute parts become necessary when the primary part experiences inventory constraints, extended lead times, or when design specifications allow for minor dimensional variations within acceptable tolerances. The ELM 1-425 maintains full compatibility with designated substitute parts that share identical electrical and mechanical characteristics within the allowed parameter range.

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 1-425 is determined by the following critical parameters:

Primary Substitution Criteria:

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

Dimensional Tolerance Parameter:

• Length: Acceptable range 0.425" to 0.440" (10.80mm to 11.18mm)

The ELM 1-425 qualifies two substitute parts: ELM 1-11MM and ELM 3-440. Both alternatives maintain identical LED type, material composition, color, and compliance certifications. The dimensional variation in length falls within the mechanical tolerance acceptable for this product category, allowing for interchangeability in applications where precise standoff height permits minor variation.

Parameter Comparison

Engineering Selection Recommendations

ELM 1-11MM Selection Criteria: The ELM 1-11MM presents a minimal dimensional deviation of 0.005" (0.12mm) from the ELM 1-425 specification. This substitute maintains all compliance certifications and active product status. Selection is appropriate for applications where the additional 0.005" height variation remains within circuit board layout and mechanical assembly tolerances.

ELM 3-440 Selection Criteria: The ELM 3-440 introduces a dimensional increase of 0.015" (2.38mm) relative to the ELM 1-425. This substitute maintains identical compliance certifications and active product status. Selection is appropriate for applications where increased standoff height accommodates design requirements or where mechanical clearance permits the additional dimension. The ELM 3-440 offers the highest inventory availability among all alternatives.

Compliance Assurance: All three parts maintain ROHS3 compliance and EAR99 export classification, ensuring regulatory consistency across substitute selections. Moisture sensitivity level remains constant at MSL 1 (Unlimited), eliminating moisture-related handling requirement changes during component substitution.

Frequently Asked Questions (FAQ)

Q: Can ELM 1-11MM be used as a direct replacement for ELM 1-425?

A: Yes. The ELM 1-11MM qualifies as a parametric equivalent. The length difference of 0.005" (0.12mm) falls within acceptable mechanical tolerance for this product category. Both parts share identical LED type (T1 3/4), material (Black PVC), color, and all compliance certifications.

Q: What is the maximum acceptable length variation for substitution?

A: Based on the provided substitute parts, the acceptable length range extends from 0.425" to 0.440" (10.80mm to 11.18mm), representing a total tolerance band of 0.015" (2.38mm).

Q: Does ELM 3-440 differ from ELM 1-425 in any compliance or material specification?

A: No. ELM 3-440 maintains identical RoHS status (ROHS3 Compliant), moisture sensitivity level (MSL 1), material composition (Black PVC), LED type (T1 3/4), and color (Black). The only difference is the increased length of 0.440" (11.18mm).

Q: Are there packaging differences between the main part and substitutes?

A: No. All three parts utilize identical bag packaging, eliminating any handling or storage procedure modifications during substitution.

Q: Which substitute part offers the best inventory availability?

A: ELM 3-440 maintains the highest inventory level at 22,638 pieces in stock, compared to ELM 1-11MM at 1,475 pieces and ELM 1-425 at 925 pieces.

Q: Do all substitute parts maintain active product status?

A: Yes. ELM 1-425, ELM 1-11MM, and ELM 3-440 are all classified as active products, ensuring continued manufacturer support and availability.
