ERM 1-795 Equivalent & Substitute Parts Reference

Part Overview

The ERM 1-795 is a LED standoff assembly manufactured by Bivar Inc., designed to accommodate 2 and 3 lead LEDs. This component features a black PVC construction with a 0.795" (20.19mm) standoff height and is classified as active product with ROHS3 compliance. Substitute parts are identified when design constraints or supply considerations require alternative standoff heights while maintaining compatibility with 2 and 3 lead LED applications.

Key Parameters

Substitute Part Grouping Explanation

The ERM 1-21MM is identified as a parametric equivalent based on the following substitution criteria:

• LED Configuration Compatibility: Both parts support 2 and 3 lead LED applications
• Material Consistency: Both utilize black PVC construction
• Series Alignment: Both belong to the ERM 1 product series
• Compliance Standards: Both maintain ROHS3 compliance and MSL 1 rating
• Variable Parameter: Standoff height differs at 0.830" (21.08mm) versus 0.795" (20.19mm)

Substitution is valid when design geometry permits the alternative height specification. The difference of 0.035" (0.89mm) between parts must be evaluated against mechanical assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the ERM 1-795 and ERM 1-21MM are active products with full ROHS3 compliance and MSL 1 ratings, establishing baseline compatibility for substitution scenarios. Selection between these parts is determined by the specific standoff height requirement of the application. The ERM 1-795 is specified for designs requiring a 0.795" standoff height, while the ERM 1-21MM accommodates applications with a 0.830" standoff height tolerance. Parts are interchangeable only when the mechanical envelope of the assembly permits the 0.035" height differential.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between ERM 1-795 and ERM 1-21MM?

A: The standoff height specification differs between the two parts. The ERM 1-795 provides a 0.795" (20.19mm) height, while the ERM 1-21MM provides a 0.830" (21.08mm) height. Both parts function identically for 2 and 3 lead LED applications.

Q: Can I use ERM 1-21MM as a substitute for ERM 1-795 in my assembly?

A: Substitution is valid only if the mechanical design accommodates the 0.035" additional height. Review printed circuit board spacing, enclosure clearances, and LED alignment tolerances to confirm fit.

Q: Are both parts ROHS3 compliant?

A: Yes, both the ERM 1-795 and ERM 1-21MM carry ROHS3 compliance certification.

Q: What is the MSL rating for these parts?

A: Both parts carry an MSL 1 (Unlimited) rating, indicating no moisture sensitivity control requirements during storage or handling.

Q: Are these parts available in other colors?

A: Based on the provided specifications, both the ERM 1-795 and ERM 1-21MM are available in black PVC only.

Q: What LED configurations do these standoffs support?

A: Both parts are designed to accommodate 2 and 3 lead LED components.
