ELM 4-700 Equivalent & Substitute Parts

Part Overview

The ELM 4-700 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.700" (17.78mm) length. This component is an active product with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). The need to identify equivalent and substitute parts arises from inventory management, production scheduling, and supply chain continuity requirements.

Key Parameters

Substitute Part Grouping Explanation

The ELM 2-17MM is identified as a parametric equivalent to the ELM 4-700 based on the following key parameters:

• LED Type: Both use T1 LED components
• Color: Both are black PVC construction
• Material: Both are manufactured from PVC
• RoHS Compliance: Both meet ROHS3 requirements
• MSL Rating: Both have MSL 1 (Unlimited) moisture sensitivity rating
• Mounting Configuration: Both are vertical standoff designs for 3MM LED applications

The primary dimensional difference is the length specification: 0.700" (17.78mm) for the ELM 4-700 versus 0.670" (17.02mm) for the ELM 2-17MM, representing a 0.030" (0.76mm) variation. This dimensional tolerance falls within acceptable mechanical equivalency for standoff applications where minor height adjustments do not affect functional performance.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 4-700 and ELM 2-17MM maintain active product status and are fully ROHS3 compliant. Selection between these parts is determined by dimensional requirements specific to the application. The ELM 4-700 provides the longer standoff length at 0.700", while the ELM 2-17MM offers a slightly shorter 0.670" configuration. Both components satisfy identical compliance and reliability standards as outlined by their MSL 1 ratings and shared manufacturing specifications.

Frequently Asked Questions (FAQ)

Q: Can the ELM 2-17MM directly replace the ELM 4-700 in existing assemblies?

A: The ELM 2-17MM differs from the ELM 4-700 by 0.030" (0.76mm) in length. Direct substitution is possible only in applications where this dimensional variance does not affect circuit board layout, component clearance, or assembly specifications.

Q: What are the critical parameters for substitution between these parts?

A: LED type (T1), color (Black), material (PVC), and RoHS/MSL compliance are functionally identical. Length is the primary differentiating parameter and must be evaluated against application requirements.

Q: Are both parts currently in production?

A: Both the ELM 4-700 and ELM 2-17MM maintain active product status with Bivar Inc.

Q: Do packaging differences affect substitutability?

A: Both parts are supplied in bag packaging and do not introduce compatibility constraints at the component level.

Q: What compliance certifications apply to both substitute options?

A: Both parts are ROHS3 compliant with MSL 1 ratings, indicating unlimited moisture sensitivity tolerance.
