ELM 3-390 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 3-390 is a T1 3/4 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.390" (9.91mm) 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 length tolerances, inventory availability, or series preferences require alternative configurations while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 3-390 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 3/4 (all substitutes maintain this specification)
• Material: Black PVC (consistent across all alternatives)
• Mounting Orientation: Vertical (standard for all listed substitutes)
• RoHS Compliance: ROHS3 Compliant (maintained across all options)
• Moisture Sensitivity Level: 1 (Unlimited) (uniform across all parts)

Secondary Variation Parameter:

• Length: Ranges from 0.375" (9.53mm) to 0.390" (9.91mm), representing a maximum variance of 0.015" (0.38mm)

The ELM 3-390 accepts substitutes within the ELM 1 and ELM 3 series that maintain identical LED type, material composition, and compliance certifications. Length variations are permissible within the specified tolerance range, as all substitute parts share the same functional mounting characteristics and electrical properties.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, confirming their suitability for current production applications. Selection between ELM 3-390 and its substitutes should be based on the following engineering considerations:

Series Selection: ELM 1-10MM provides identical length specification (0.390") while offering higher inventory availability (947 pcs vs. 719 pcs). ELM 3-375 represents the longest available inventory position (8835 pcs) but introduces a 0.015" length reduction.

Length Tolerance Accommodation: Applications requiring exact 0.390" standoff height should prioritize ELM 3-390 or ELM 1-10MM. Applications tolerating length variation within 0.015" may utilize ELM 1-385 (0.385") or ELM 3-375 (0.375").

Inventory Considerations: ELM 3-375 provides maximum stock availability for high-volume procurement scenarios. ELM 1-385 and ELM 1-10MM offer intermediate inventory levels suitable for standard production runs.

All substitutes maintain identical electrical and mechanical properties, moisture sensitivity ratings, and compliance certifications as the primary part.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the ELM 3-390?

A: Substitute parts must maintain T1 3/4 LED type, black PVC material composition, vertical mounting orientation, ROHS3 compliance, and MSL 1 rating. Length variations up to 0.015" are permissible within the ELM 1 and ELM 3 series.

Q: Can ELM 1-385 replace ELM 3-390 in all applications?

A: ELM 1-385 is functionally equivalent with a 0.005" shorter length (0.385" vs. 0.390"). Substitution is valid for applications where this length tolerance is acceptable. Verify mechanical clearance requirements in your specific assembly.

Q: What is the maximum length difference between substitute options?

A: The maximum length variance is 0.015" (0.38mm), occurring between ELM 3-375 (0.375") and ELM 3-390 (0.390"). All intermediate lengths fall within this range.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the primary part specification.

Q: Which substitute offers the best inventory availability?

A: ELM 3-375 provides the highest inventory position at 8835 pcs, followed by ELM 1-10MM at 947 pcs and ELM 1-385 at 750 pcs.

Q: Do ELM 1 and ELM 3 series parts have different electrical properties?

A: No. Both series maintain identical LED type (T1 3/4), material (black PVC), and compliance specifications. Series designation reflects design iteration rather than functional differentiation.

Q: What packaging format applies to all substitute parts?

A: All parts are supplied in Bag packaging format, consistent with standard component distribution for LED standoff assemblies.
