ERM 1-22MM Equivalent & Substitute Parts

Part Overview

The ERM 1-22MM is an LED standoff manufactured by Bivar Inc., designed for 2 and 3 lead LED applications. This black PVC standoff measures 0.870" (22.10mm) in length and is classified as an active product with ROHS3 compliance. Finding equivalent or substitute parts may be necessary due to inventory constraints, supply chain considerations, or application-specific requirements while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERM 1-22MM is determined by the following critical parameters:

• Series membership (ERM 1 family)
• LED configuration compatibility (2 and 3 lead support)
• Material composition (Black PVC)
• RoHS compliance status (ROHS3 Compliant)
• Moisture sensitivity level (MSL 1)
• Base product number alignment (ERM1-2)

The ERM 1-21MM qualifies as a parametric equivalent based on matching all core electrical and mechanical criteria within the allowed tolerance range for this product category. The primary distinction is the length specification: 0.830" (21.08mm) versus 0.870" (22.10mm).

Parameter Comparison

Engineering Selection Recommendations

Both the ERM 1-22MM and ERM 1-21MM maintain active product status and full ROHS3 compliance. Selection between these parts should be based on the specific mechanical clearance requirements of the application. The 0.040" (1.02mm) length difference between the two standoffs is the determining factor for compatibility in space-constrained assemblies. Both parts carry identical MSL ratings and support the same LED lead configurations, ensuring functional equivalence within their respective dimensional specifications.

Frequently Asked Questions (FAQ)

Q: Can the ERM 1-21MM be used as a direct replacement for the ERM 1-22MM?

A: The ERM 1-21MM is a parametric equivalent with identical electrical and material properties. Substitution is valid only if the application tolerates a 0.040" (1.02mm) reduction in standoff height. Verify mechanical clearance in your specific assembly before implementation.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry ROHS3 compliance and MSL 1 ratings. Regulatory and environmental requirements are equivalent.

Q: Do both parts support the same LED configurations?

A: Yes. Both the ERM 1-22MM and ERM 1-21MM are designed for 2 and 3 lead LED applications with identical material and color specifications.

Q: What is the significance of the base product number ERM1-2?

A: The base product number indicates both parts belong to the same product family within the ERM 1 series, confirming their functional relationship and design compatibility.

Q: Are packaging considerations different between these parts?

A: Both parts are supplied in bag packaging. Verify inventory availability and lead times based on your procurement requirements.
