ELM 4-325 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-325 is a T1 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.325" (8.26mm) length. This component is designed for vertical mounting applications requiring precise standoff height specifications. The part maintains Active product status and is RoHS3 compliant with MSL Level 1 rating, indicating unlimited moisture sensitivity tolerance.

Substitute parts become necessary when the primary part number reaches inventory constraints, when design revisions require alternative standoff heights within acceptable tolerances, or when supply chain optimization requires sourcing from available stock alternatives that maintain functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-325 is determined by the following critical parameters:

Primary Substitution Criteria:

• LED Type: T1 (all substitutes maintain T1 specification)
• Material: Black PVC (all substitutes maintain black PVC construction)
• Mounting Style: Vertical (all substitutes maintain vertical orientation)
• Manufacturer: Bivar Inc. (all substitutes from same manufacturer)
• Color: Black (all substitutes maintain black color)
• RoHS Status: ROHS3 Compliant (all substitutes maintain compliance)
• MSL Rating: Level 1 (all substitutes maintain unlimited moisture tolerance)

Secondary Substitution Parameter:

• Length: 0.325" (8.26mm) primary specification with acceptable alternatives at 0.315" (8.00mm) and 0.320" (8.13mm) within the ELM series family

The ELM 4-325 belongs to the ELM 4 series. Substitutes include parts from both the ELM 4 series (ELM 4-315) and the ELM 2 series (ELM 2-315, ELM 2-320), all sharing identical core functional parameters with length variations representing the primary design difference.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory and supply chain continuity. The ELM 4-315 represents the closest substitute within the same ELM 4 series, differing only in length specification (0.315" versus 0.325"). The ELM 2-320 and ELM 2-315 provide alternatives from the ELM 2 series with comparable length specifications.

Selection between substitutes should be based on specific application height requirements and available inventory levels. The ELM 2-320 offers the highest current inventory availability at 26,182 pieces, while the ELM 4-315 maintains series consistency with the primary part at 4,972 pieces in stock.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-315 directly replace ELM 4-325 in all applications?

A: The ELM 4-315 differs from ELM 4-325 only in length specification (0.315" versus 0.325"). Direct substitution is valid only when the 0.010" (0.26mm) height reduction does not affect circuit board layout, component clearance, or functional requirements. All other parameters remain identical.

Q: What is the difference between ELM 4 and ELM 2 series substitutes?

A: Both series share identical LED type (T1), material (black PVC), color, and compliance specifications. The primary distinction is series designation. ELM 4 series parts maintain exact series consistency with the primary part number. ELM 2 series parts provide functional equivalence with alternative length options.

Q: Are length variations between 0.315", 0.320", and 0.325" functionally equivalent?

A: Length variations represent design differences. Substitution validity depends on application-specific height requirements. The 0.010" difference between 0.315" and 0.325" and the 0.005" difference between 0.320" and 0.325" must be evaluated against circuit board design constraints and component spacing requirements.

Q: Do all substitute parts maintain the same compliance certifications?

A: Yes. All substitute parts are ROHS3 compliant with MSL Level 1 rating, matching the primary ELM 4-325 specification. Compliance status remains consistent across all listed alternatives.

Q: What packaging format applies to all parts in this substitution group?

A: All parts in this group are supplied in Bag packaging format, maintaining consistent handling and storage requirements across the substitution family.
