ELM 1-810 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 1-810 is a T1 3/4 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.810" (20.57mm) length. This component is part of the active ELM 1 series and is ROHS3 compliant. Substitute parts become necessary when the primary component is unavailable due to inventory constraints or when design specifications permit dimensional tolerance variations within the established parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

The ELM 1-820 qualifies as a parametric equivalent to the ELM 1-810 based on the following criteria:

Matching Parameters:

• Identical manufacturer (Bivar Inc.)
• Identical series designation (ELM 1)
• Identical LED type (T1 3/4)
• Identical material (Black PVC)
• Identical RoHS compliance status (ROHS3 Compliant)
• Identical moisture sensitivity level (MSL 1 - Unlimited)
• Identical product status (Active)

Differential Parameter:

• Length variation: 0.820" (20.83mm) versus 0.810" (20.57mm), representing a 0.010" (0.26mm) dimensional difference

Substitution validity depends on design tolerance acceptance for the 0.010" length differential. When mounting clearance and board spacing permit this dimensional variation, the ELM 1-820 functions as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 1-810 and ELM 1-820 are active products with identical RoHS3 compliance and moisture sensitivity classifications. The ELM 1-810 provides availability of 1,079 pieces, while the ELM 1-820 offers 1,983 pieces in current inventory. The single dimensional difference of 0.010" in length must be evaluated against circuit board layout and mechanical clearance requirements. Selection should be based on design tolerance specifications and current availability needs.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between ELM 1-810 and ELM 1-820? A: The ELM 1-820 features a 0.010" (0.26mm) greater length (0.820" versus 0.810"). All other electrical and mechanical characteristics, including LED type, material, color, and compliance certifications, are identical.

Q: Can ELM 1-820 be used as a direct replacement for ELM 1-810? A: Substitution is valid when the design tolerance permits a 0.010" length differential. Verification of mounting clearance and PCB spacing is required before substitution.

Q: Are both parts ROHS3 compliant? A: Yes, both ELM 1-810 and ELM 1-820 are ROHS3 compliant with an MSL rating of 1 (Unlimited).

Q: Which part should I select based on availability? A: The ELM 1-820 currently maintains higher inventory (1,983 pieces) compared to the ELM 1-810 (1,079 pieces). Selection should prioritize the ELM 1-810 if length specifications are critical; otherwise, the ELM 1-820 availability advantage may be preferred.

Q: Do both parts use identical packaging? A: Yes, both parts are supplied in bag packaging format.
