ERM 1-845 Equivalent & Substitute Parts

Part Overview

The ERM 1-845 is a 2 and 3 Lead LED Standoff manufactured by Bivar Inc., designed for vertical mounting applications with universal compatibility. This component features a black PVC construction with a 0.845" (21.46mm) standoff height, suitable for LED assembly integration in electronic equipment. The part maintains Active product status and is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity tolerance. Substitute parts are identified when equivalent electrical and mechanical parameters align within the allowed specifications for this LED standoff category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERM 1-845 is determined by the following critical parameters:

Primary Substitution Criteria:

• Series alignment (ERM 1 family)
• LED configuration compatibility (2 and 3 Lead LEDs)
• Material specification (Black PVC)
• Mounting orientation (Vertical)
• Manufacturer (Bivar Inc.)
• Compliance certifications (ROHS3, MSL 1)

Dimensional Tolerance: Length specifications within the ERM 1 series allow for minor dimensional variation. The ERM 1-845 (0.845" / 21.46mm) and ERM 1-21MM (0.830" / 21.08mm) both fall within the universal standoff height range for this product category, maintaining functional equivalence for vertical LED mounting applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ERM 1-845 and ERM 1-21MM maintain Active product status with identical compliance certifications (ROHS3 Compliant, MSL 1). The dimensional difference of 0.016" (0.38mm) between the two parts represents a 1.8% variance in standoff height. Selection between these parts is determined by specific application height requirements within the ERM 1 series universal mounting specification. Both parts are suitable for 2 and 3 Lead LED applications with equivalent electrical performance characteristics within the Bivar Inc. ERM 1 product line.

Frequently Asked Questions (FAQ)

Q: What determines if ERM 1-21MM can substitute for ERM 1-845?

A: Substitution is valid when the following parameters align: same manufacturer (Bivar Inc.), same series (ERM 1), same LED configuration (2 and 3 Lead), same material (Black PVC), same mounting orientation (Vertical), and identical compliance ratings (ROHS3, MSL 1). The dimensional variance of 0.016" falls within the universal standoff specification for this product category.

Q: Are there electrical performance differences between ERM 1-845 and ERM 1-21MM?

A: Both parts are LED standoffs with identical electrical specifications. The difference is mechanical height only. No electrical parameter variance exists between these parts.

Q: Can these parts be used interchangeably in all applications?

A: Interchangeability depends on application-specific height tolerance requirements. The 0.016" (0.38mm) dimensional difference must be evaluated against your PCB layout and component clearance specifications.

Q: What is the packaging format for both parts?

A: Both ERM 1-845 and ERM 1-21MM are supplied in Bag packaging format.

Q: Are both parts RoHS compliant?

A: Yes. Both ERM 1-845 and ERM 1-21MM are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating.
