ELM 1-505 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 1-505 is an active T1 3/4 LED standoff manufactured by Bivar Inc., featuring a black PVC body with a 0.505" (12.83mm) length. This component is classified as ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), indicating suitability for general-purpose applications without environmental constraints. Substitute parts are identified when mechanical and electrical parameters align, allowing drop-in compatibility for design flexibility and supply chain alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 1-505 is determined by the following critical parameters: LED type (T1 3/4), color (black), and mechanical form factor compatibility. Length variations within the T1 3/4 family are acceptable within standard tolerance ranges (±0.010"), as the standoff dimensions maintain functional compatibility in typical PCB mounting applications. Material differences (PVC versus Nylon) are permitted substitutes when the base LED type and dimensional envelope remain equivalent. All identified substitutes maintain ROHS3 compliance and EAR99 classification, ensuring regulatory and export consistency.

Key Parameters for Substitution:

• LED Type: T1 3/4 (fixed requirement)
• Color: Black (fixed requirement)
• Length: 0.500" to 0.510" (acceptable range)
• Material: PVC or Nylon (compatible alternatives)
• RoHS & Compliance: ROHS3 Compliant (required)

Parameter Comparison

Engineering Selection Recommendations

All four parts (ELM 1-505, ELM 1-13MM, ELM 3-500, and H-278C-2) maintain active product status with ROHS3 compliance and EAR99 export classification. Selection among these equivalents should be based on inventory availability and material preference. The PVC-bodied variants (ELM 1-505, ELM 1-13MM, ELM 3-500) are functionally equivalent with length deviations of less than 0.015", which falls within standard mechanical tolerances for LED standoff applications. The H-278C-2 Nylon alternative provides identical electrical and dimensional characteristics, offering an alternative material composition when PVC availability is constrained.

Frequently Asked Questions (FAQ)

Q: Can ELM 1-13MM replace ELM 1-505 directly? A: Yes. Both parts share identical LED type (T1 3/4), color (black), material (PVC), and RoHS status. The 0.005" length difference (12.95mm vs. 12.83mm) is within standard mechanical tolerance for LED standoff applications and does not affect functional performance.

Q: What is the difference between ELM 3-500 and ELM 1-505? A: Both are T1 3/4 black LED standoffs with equivalent mechanical dimensions (ELM 3-500 at 0.500", ELM 1-505 at 0.505"). They belong to different product series (ELM 3 versus ELM 1) but maintain identical form factor, material (PVC), and compliance certifications. The length variation of 0.005" is within acceptable tolerance.

Q: Is the H-278C-2 (Nylon) compatible with applications designed for ELM 1-505 (PVC)? A: Yes. Both parts are mechanically and electrically equivalent with identical LED type, color, and length dimensions. The material difference (Nylon versus PVC) does not affect compatibility in standard PCB-mounted LED standoff applications. Select based on material availability and design requirements.

Q: Are all substitutes ROHS3 compliant? A: Yes. ELM 1-505, ELM 1-13MM, ELM 3-500, and H-278C-2 are all ROHS3 compliant with MSL 1 or not applicable ratings, suitable for unrestricted use in compliant assemblies.

Q: What inventory is available for each part? A: ELM 1-505 (1,003 units), ELM 1-13MM (20,735 units), ELM 3-500 (32,418 units), and H-278C-2 (1,446 units) are in stock as new original inventory.
