ERM 1-470 Equivalent & Substitute Parts

Part Overview

The ERM 1-470 is an LED standoff assembly manufactured by Bivar Inc., designed to support 2 and 3 lead LEDs in vertical orientation. This component uses black PVC material with a 0.470" (11.94mm) height specification and is suitable for universal LED mounting applications. The product maintains Active status with ROHS3 compliance and MSL Level 1 (Unlimited moisture sensitivity). Finding equivalent substitute parts is necessary when the primary part is unavailable or when design flexibility permits alternative height configurations that maintain functional compatibility.

Substitute Part Grouping Explanation

Substitute compatibility for the ERM 1-470 is determined by the following criteria:

• Manufacturer: Must be Bivar Inc. to ensure consistent mechanical and thermal properties
• Series: Must belong to the ERM 1 series to maintain design consistency
• LED Compatibility: Must support 2 and 3 lead LEDs
• Material: Must be black PVC to match environmental resistance and physical properties
• RoHS Compliance: Must meet ROHS3 standard
• Moisture Sensitivity: Must maintain MSL Level 1 classification

The primary variable parameter permitting substitution is Length (Height). The ERM 1 series accommodates different standoff heights for applications requiring vertical spacing adjustments while maintaining all other functional characteristics.

Engineering Selection Recommendations

Both the ERM 1-470 and ERM 1-450 maintain Active product status with full ROHS3 compliance and MSL Level 1 certification. Selection between these parts depends on the specific vertical height requirement for your application. The ERM 1-470 provides 0.470" (11.94mm) height, while the ERM 1-450 provides 0.450" (11.43mm) height—a 0.020" (0.51mm) difference. Both parts are qualified for identical LED lead configurations and environmental conditions. Choose the ERM 1-450 when inventory availability is critical, as current stock levels show 15,251 units compared to 989 units for the ERM 1-470.

Frequently Asked Questions (FAQ)

Q: Can the ERM 1-450 directly replace the ERM 1-470 in existing designs? A: The ERM 1-450 can serve as a mechanical substitute if your design accommodates the 0.020" (0.51mm) height reduction. Both parts support identical LED configurations and offer equivalent electrical and environmental performance.

Q: Are there compatibility concerns with different PCB hole patterns? A: The ERM 1 series maintains consistent base product design (ERM1-4). Both the ERM 1-470 and ERM 1-450 use universal mounting provisions for 2 and 3 lead LEDs. Verify your specific hole pattern against the mechanical drawings to confirm fit.

Q: How does the height difference affect LED standoff performance? A: Both parts use black PVC material with identical moisture sensitivity and RoHS compliance. The height difference affects only the vertical spacing between the PCB and the LED component. Functionality and reliability remain equivalent.

Q: What is the minimum lead count supported by these standoffs? A: Both the ERM 1-470 and ERM 1-450 support 2 and 3 lead LED configurations. Verify your specific LED type (2-lead or 3-lead) matches this specification before selection.

Q: Are there supply chain considerations when selecting between these alternatives? A: The ERM 1-450 carries significantly higher inventory levels. For time-sensitive applications requiring immediate availability, the ERM 1-450 may be the preferred choice, provided the height specification matches your design requirements.
