Substitute Part Grouping Explanation

Substitution for the ERM 1-850 is based on the following critical parameters:

Primary Substitution Criteria:

• Manufacturer: Bivar Inc. (same manufacturer ensures design consistency)
• Series: ERM 1 (same product family)
• LED Configuration: 2 and 3 Lead LEDs (identical electrical interface)
• Material: Black PVC (same material composition)
• Mounting Style: Vertical (same orientation)
• RoHS Status: ROHS3 Compliant (regulatory equivalence)
• Moisture Sensitivity Level: 1 (Unlimited) (identical environmental rating)

Secondary Consideration:

• Length tolerance: Parts within the ERM 1 series with nominal lengths of 0.830" to 0.850" are mechanically compatible within standard assembly tolerances for LED standoff applications.

The substitute part ERM 1-21MM meets all primary criteria and operates within acceptable mechanical parameters for universal LED mounting applications.

Engineering Selection Recommendations

ERM 1-850 Primary Selection: Use the ERM 1-850 when the exact 0.850" (21.59mm) length is specified in the design documentation or when current inventory supports immediate procurement.

ERM 1-21MM Substitute Selection: The ERM 1-21MM is a valid substitute when:

• Design specifications allow for a 0.020" (0.51mm) length reduction
• The application does not require the exact 0.850" dimension
• Supply chain or inventory considerations favor the substitute part
• Both parts maintain identical electrical, material, and compliance characteristics

Both parts are Active products with ROHS3 compliance and MSL 1 rating, ensuring equivalent performance in production environments. Selection between these parts should be based on design tolerance requirements and procurement availability.

Frequently Asked Questions (FAQ)

Q: Can ERM 1-21MM be used as a direct replacement for ERM 1-850?

A: ERM 1-21MM is a mechanical and electrical equivalent within standard assembly tolerances. The 0.020" (0.51mm) length difference must be evaluated against design specifications. Both parts share identical material, LED configuration, mounting style, and compliance ratings.

Q: What is the significance of the length difference between these parts?

A: The ERM 1-850 has a nominal length of 0.850" (21.59mm), while the ERM 1-21MM has a nominal length of 0.830" (21.08mm). This 0.020" difference is typical within the ERM 1 series and is acceptable for universal LED mounting applications where standoff height tolerance is not critical to circuit board clearance or component spacing.

Q: Are both parts ROHS3 compliant?

A: Yes. Both ERM 1-850 and ERM 1-21MM are ROHS3 compliant and carry an MSL rating of 1 (Unlimited), indicating equivalent environmental and regulatory suitability for production use.

Q: What LED configurations do these standoffs support?

A: Both parts are designed for 2 and 3 lead LED applications, providing universal compatibility across standard LED component types within this lead count range.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in Bag packaging format, consistent with standard component distribution for LED standoff assemblies.
