ERM 1-115 LED Standoff: Equivalent & Substitute Parts

Part Overview

The ERM 1-115 is a 2 and 3 lead LED standoff manufactured by Bivar Inc., designed for universal LED mounting applications. This black PVC standoff features a height of 0.115" (2.92mm) and is actively produced and stocked. The availability of substitute parts with slightly different heights enables design flexibility and accommodates varying PCB layout requirements while maintaining functional equivalence for LED positioning and alignment in circuit assemblies.

Key Parameters

Substitute Part Grouping Explanation

The ERM 1-110 is a parametric equivalent to the ERM 1-115 within the ERM 1 series family. Substitution between these parts is determined by the following key parameters that must remain compatible:

• Series Membership: Both parts belong to the ERM 1 series
• Manufacturer: Both manufactured by Bivar Inc.
• LED Configuration: Both support 2 and 3 lead LED mounting
• Material Composition: Both constructed from black PVC
• Color: Both black
• Product Status: Both actively produced
• Compliance Certifications: Both ROHS3 compliant with MSL 1 rating

The primary dimensional difference is standoff height: ERM 1-115 specifies 0.115" (2.92mm) while ERM 1-110 specifies 0.110" (2.79mm), a 0.005" (0.13mm) height variance. This difference permits substitution when PCB layout tolerances and LED positioning requirements allow for the 0.13mm height reduction.

Parameter Comparison

Engineering Selection Recommendations

Both ERM 1-115 and ERM 1-110 maintain active production status with ROHS3 compliance and MSL 1 certification, ensuring both parts meet current regulatory requirements for lead-free component usage. Selection between these parts is determined by mechanical height requirements in the PCB assembly:

• ERM 1-115 is specified for applications requiring 0.115" (2.92mm) standoff height
• ERM 1-110 serves applications accommodating 0.110" (2.79mm) standoff height

The 0.005" height difference represents the sole mechanical variance. Substitution of ERM 1-110 for ERM 1-115 is permissible only when design specifications allow for the reduced height and when PCB layout tolerances accommodate the dimensional change.

Frequently Asked Questions (FAQ)

Q: Can ERM 1-110 directly replace ERM 1-115 in all applications?

A: No. While both parts share identical material, color, LED configuration, and compliance certifications, the 0.005" (0.13mm) height difference means substitution is limited to applications where PCB layout and mechanical clearance specifications permit the reduced standoff height. Design specifications must be reviewed before substitution.

Q: Are there differences in LED mounting compatibility between these parts?

A: No. Both ERM 1-115 and ERM 1-110 accommodate 2 and 3 lead LED configurations identically. The difference is only in standoff height above the PCB surface.

Q: Do both parts meet current RoHS and moisture sensitivity requirements?

A: Yes. Both parts carry ROHS3 compliance and MSL 1 (Unlimited) certification, confirming suitability for modern manufacturing and storage environments without moisture baking requirements.

Q: What determines which part number should be used?

A: PCB layout and mechanical design requirements determine selection. The specified standoff height in your assembly design dictates whether ERM 1-115 (0.115") or ERM 1-110 (0.110") is appropriate.

Q: Are inventory levels a factor in part selection?

A: Inventory availability may influence procurement decisions. ERM 1-110 currently maintains higher stock levels (6002 pcs) compared to ERM 1-115 (1025 pcs), but substitution remains a mechanical decision based on design requirements, not inventory status.
