ELM 1-240 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 1-240 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a 0.240" (6.10mm) length specification. The part maintains Active product status and is RoHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity tolerance.

Substitute parts become necessary when the primary part experiences inventory constraints, extended lead times, or when design specifications allow for dimensional or material variations within acceptable tolerances. The substitute parts listed below maintain functional equivalence through matching LED form factor, color, compliance certifications, and mechanical compatibility parameters.

Substitute Part Grouping Explanation

Substitution logic for the ELM 1-240 is based on the following allowed parameters:

Primary Substitution Criteria (Exact Match Required):

• LED Form Factor: T1 3/4 (all substitutes maintain this specification)
• Color: Black (all substitutes maintain this specification)
• Mounting Orientation: Vertical (all substitutes maintain this specification)
• RoHS Status: ROHS3 Compliant (all substitutes maintain this specification)
• MSL Rating: 1 (Unlimited) (all substitutes maintain this specification)

Secondary Substitution Criteria (Allowable Variation):

• Length: 0.235" (5.97mm) to 0.250" (6.35mm) represents acceptable dimensional tolerance range
• Material: PVC or Nylon acceptable for mechanical compatibility
• Series: ELM 1 or ELM 3 series acceptable based on lead design compatibility

The substitute parts are grouped into two categories based on dimensional and material specifications while maintaining all critical functional parameters.

Parameter Comparison

Engineering Selection Recommendations

Direct Dimensional Equivalent: ELM 1-6MM represents the closest substitute to ELM 1-240, matching the exact length specification of 0.240" (6.10mm), material composition (PVC), and series designation (ELM 1). This part maintains identical compliance certifications and MSL rating.

Length Tolerance Substitutes: ELM 1-250 and ELM 3-250 provide 0.250" (6.35mm) length specification, representing a +0.010" (0.25mm) dimensional increase. ELM 3-235 and 909-235 BK provide 0.235" (5.97mm) length specification, representing a -0.005" (0.13mm) dimensional decrease. These parts maintain all critical compliance parameters and are suitable where dimensional tolerance permits.

Material Variant: 909-235 BK substitutes Nylon material for PVC while maintaining all other critical specifications. This part is suitable where material compatibility with application environment permits.

Compliance Status: All substitute parts maintain ROHS3 compliance, MSL 1 rating, and Active product status, ensuring regulatory and environmental requirement alignment with the primary part.

Frequently Asked Questions (FAQ)

Q: Can ELM 1-250 be used as a direct replacement for ELM 1-240? A: ELM 1-250 is functionally equivalent with a length specification of 0.250" (6.35mm) compared to the primary part's 0.240" (6.10mm). The +0.010" dimensional difference is acceptable where design specifications permit length tolerance. Both parts share identical material (PVC), series (ELM 1), and compliance certifications.

Q: What is the difference between ELM 1 and ELM 3 series substitutes? A: ELM 1 and ELM 3 series differ in lead design configuration. Both series maintain identical LED form factor (T1 3/4), color (Black), compliance status (ROHS3), and MSL rating (1). Series selection depends on specific lead compatibility requirements for your application.

Q: Is 909-235 BK suitable as a substitute despite the Nylon material difference? A: 909-235 BK substitutes Nylon material for the primary part's PVC construction. Both materials are black and maintain identical LED form factor, compliance certifications, and MSL rating. Material selection depends on application-specific environmental and mechanical requirements.

Q: What length variations are acceptable among substitute parts? A: Substitute parts range from 0.235" (5.97mm) to 0.250" (6.35mm), representing a total tolerance band of ±0.015" around the primary specification of 0.240" (6.10mm). Length selection depends on specific design clearance and mounting requirements.

Q: Do all substitute parts maintain the same compliance certifications? A: All substitute parts listed maintain ROHS3 compliance, MSL 1 (Unlimited) rating, and Active product status, ensuring equivalent regulatory and environmental compliance with the primary ELM 1-240 part.

Q: Which substitute offers the highest inventory availability? A: ELM 1-250 provides the highest inventory level at 52,009 pieces, followed by 909-235 BK at 37,872 pieces. Inventory levels should be verified for current availability when component selection is finalized.
