ERM 1-250 Equivalent & Substitute Parts

Part Overview

The ERM 1-250 is a 2 and 3 Lead LED Standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.250" (6.35mm) vertical mounting height for universal LED applications. The product is Active status and ROHS3 compliant. Substitute parts are identified when dimensional and material specifications align within allowable tolerances while maintaining functional compatibility with 2 and 3 lead LED configurations.

Key Parameters

Substitute Part Grouping Explanation

The ERM 1-6MM qualifies as a parametric equivalent based on the following criteria:

Key Substitution Parameters:

• LED Configuration: Both support 2 and 3 lead LEDs
• Material: Both are black PVC construction
• Series: Both belong to the ERM 1 series
• Product Status: Both are Active
• RoHS Compliance: Both are ROHS3 compliant
• Moisture Sensitivity Level: Both are MSL 1 (Unlimited)
• Color: Both are black

Dimensional Tolerance: The length specifications are 0.250" (6.35mm) and 0.240" (6.10mm), representing a 0.010" (0.25mm) dimensional variance within the universal mounting application range of the ERM 1 series.

Parameter Comparison

Engineering Selection Recommendations

Both the ERM 1-250 and ERM 1-6MM are Active products with ROHS3 compliance and MSL 1 ratings, meeting regulatory and environmental requirements. The selection between these parts depends on application-specific PCB layout constraints and mounting height requirements. The ERM 1-250 provides a 0.250" standoff height, while the ERM 1-6MM provides a 0.240" height. Both parts share identical LED lead configurations, material composition, and moisture sensitivity characteristics, ensuring functional compatibility within the ERM 1 series specifications.

Frequently Asked Questions (FAQ)

Q: What determines if ERM 1-6MM can substitute for ERM 1-250? A: The parts share identical LED lead configurations, material composition, series designation, RoHS compliance status, and moisture sensitivity level. The dimensional difference of 0.010" represents the primary variation and must be evaluated against application-specific clearance and mounting height requirements.

Q: Are there any compliance or certification differences between these parts? A: No. Both parts carry ROHS3 compliance and identical moisture sensitivity ratings (MSL 1), confirming equivalent environmental and regulatory standing.

Q: Does the length difference affect LED lead compatibility? A: Both parts support 2 and 3 lead LED configurations identically. The length difference relates to the PVC standoff height only and does not affect lead count compatibility.

Q: Can ERM 1-6MM be used directly in place of ERM 1-250? A: Substitution is feasible for applications where the 0.010" height reduction does not affect PCB clearance, component spacing, or functional performance requirements. Application-specific design validation is necessary.
