ELM 4-125 Equivalent & Substitute Parts

Part Overview

The ELM 4-125 is a T1 LED standoff manufactured by Bivar Inc., designed with black PVC construction and a vertical mounting configuration. This component is engineered for LED positioning and isolation in electronic assemblies. The part maintains Active product status and complies with ROHS3 standards. Substitute parts become necessary when design specifications allow for alternative physical dimensions, inventory constraints exist, or supply chain optimization is required while maintaining functional equivalency.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 4-125 are qualified based on the following allowable parameters:

Common Parameters Across All Substitutes:

• Manufacturer: Bivar Inc.
• LED Type: T1
• Material: Black PVC
• Configuration: Vertical Mount, Single Row
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Product Status: Active

Variable Parameter (Substitution Basis):

• Length: The substitute parts ELM 2-120 and ELM 5-130 differ in length specifications (0.120" and 0.130" respectively) compared to the main part (0.125"). These length variations remain within the same component category and functional class, allowing substitution when design specifications permit dimensional tolerance.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts (ELM 2-120 and ELM 5-130) maintain compliance with ROHS3 standards and Moisture Sensitivity Level 1 (Unlimited), ensuring regulatory equivalency with the primary part ELM 4-125. Selection between substitutes is determined by design allowances for length variation. The ELM 2-120 provides a shorter profile at 0.120" (3.05mm), while the ELM 5-130 provides an extended profile at 0.130" (3.30mm). All parts are manufactured by Bivar Inc. and retain Active product status, supporting long-term supply chain stability. Inventory availability should be evaluated against application requirements.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-120 and ELM 5-130 be used interchangeably with ELM 4-125? A: Substitution depends on design specifications. The parts are functionally equivalent in material composition, LED type, configuration, and compliance status. The critical difference is length specification: ELM 2-120 is 0.120" (3.05mm), ELM 4-125 is 0.125" (3.18mm), and ELM 5-130 is 0.130" (3.30mm). Use ELM 2-120 or ELM 5-130 only if design tolerance permits the respective length variation.

Q: What are the key parameters that determine substitute compatibility? A: Compatibility is established through matching: LED type (T1), material (black PVC), configuration (vertical mount, single row), manufacturer (Bivar Inc.), and compliance certifications (ROHS3, MSL 1). Length is the allowable variable parameter for these substitutes.

Q: Are all substitute parts RoHS compliant? A: Yes, ELM 2-120 and ELM 5-130 are both ROHS3 Compliant, matching the primary part specification.

Q: What is the inventory status of the substitute parts? A: ELM 2-120 has 86,435 pieces available. ELM 5-130 has 1,461 pieces available. The primary part ELM 4-125 has 750 pieces available.

Q: Do the substitute parts have the same moisture sensitivity level? A: Yes, all parts including ELM 2-120 and ELM 5-130 have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions.
