ELM 4-195 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-195 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.195" (4.95mm) height. This component is actively produced and ROHS3 compliant, making it suitable for modern electronic assemblies. Finding alternative models becomes necessary when inventory constraints occur or when design specifications allow for minor dimensional variations within acceptable tolerances.

Key Parameters

Substitute Part Grouping Explanation

The ELM 2-5MM is identified as a parametric equivalent to the ELM 4-195 based on the following criteria:

Common Parameters:

• LED Type: T1 (identical form factor)
• Material: PVC (identical construction material)
• Color: Black (identical visual specification)
• Manufacturer: Bivar Inc. (same manufacturer)
• RoHS Status: ROHS3 Compliant (equivalent environmental compliance)
• MSL Rating: 1 (unlimited moisture sensitivity level)
• Mounting Style: Vertical (same orientation)

Dimensional Variance:

• ELM 4-195: 0.195" (4.95mm) length
• ELM 2-5MM: 0.200" (5.08mm) length

The 0.005" (0.13mm) difference in height falls within acceptable tolerances for T1 LED standoff applications where the primary functional requirement is vertical mounting of a T1 LED component with PVC insulation.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 4-195 and ELM 2-5MM are active production components manufactured by Bivar Inc. with identical ROHS3 compliance and MSL ratings. The primary distinction is the 0.005" height differential. Selection should be based on:

1. Design Tolerance: If PCB layout or assembly clearances require the exact 0.195" height, the ELM 4-195 is the specified component.
2. Availability: The ELM 2-5MM offers higher inventory availability (2755 pieces versus 806 pieces), making it suitable for high-volume production when dimensional tolerance permits.
3. Compliance: Both components meet identical environmental and safety certifications, eliminating compliance-based constraints on substitution.

Frequently Asked Questions (FAQ)

Q: Can the ELM 2-5MM directly replace the ELM 4-195? A: Substitution is permissible only when design specifications allow for a 0.005" (0.13mm) increase in standoff height. This typically applies to applications where mechanical clearance and solder joint geometry are not critical constraints. Verify PCB design specifications before implementing the substitute.

Q: What are the key parameters that determine substitutability? A: Substitutability depends on matching the LED type (T1), material (PVC), color (Black), mounting orientation (Vertical), and maintaining compatible height tolerances. Both components meet these criteria with the noted dimensional variance.

Q: Are there compliance differences between these parts? A: Both components are ROHS3 compliant with MSL 1 ratings (unlimited moisture sensitivity protection). No compliance constraints prevent substitution.

Q: What inventory considerations apply? A: The ELM 2-5MM maintains higher stock levels, reducing lead times for component procurement. The ELM 4-195 maintains lower inventory, which may impact availability for standard replenishment cycles.

Q: Does the 0.005" height difference affect functionality? A: The height differential does not affect LED functionality, as both components perform the same T1 standoff function. Impact assessment depends on PCB design constraints, assembly process requirements, and mechanical clearance margins specific to the application.
