Substitute Part Grouping Explanation

The ELM 5-940 accepts substitution with ELM 5-23MM based on the following criteria:

• Series Compatibility: Both parts belong to the ELM 5 series, ensuring mechanical mounting compatibility
• LED Type Match: Both use T1 LED type, maintaining electrical interface consistency
• Material & Color: Both feature black PVC construction, preserving mechanical and environmental properties
• Height Tolerance: ELM 5-23MM has a length of 0.910" (23.11mm), representing a 0.030" (0.79mm) dimensional difference from the main part
• Electrical Compliance: Both meet ROHS3 compliance and share identical ECCN and HTSUS codes
• Moisture Sensitivity: Both classified as MSL 1 (Unlimited), indicating equivalent environmental performance

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 5-940 and ELM 5-23MM are Active-status products with identical RoHS3 compliance certification, MSL 1 rating, and matching regulatory classifications (ECCN and HTSUS codes). The selection between these parts depends on application-specific height requirements. The ELM 5-940 provides the full 0.940" height specification, while the ELM 5-23MM offers a 0.030" shorter alternative within the same mechanical and electrical framework. Both parts maintain identical material composition, color specification, and environmental performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can ELM 5-23MM be directly substituted for ELM 5-940 in existing designs?

A: Direct substitution is technically feasible when the 0.030" height difference does not affect circuit board layout or mechanical clearance requirements. Both parts share identical LED type, material, color, series designation, and compliance certifications.

Q: Are there electrical differences between ELM 5-940 and ELM 5-23MM?

A: No electrical differences exist. Both parts use T1 LED type and share identical moisture sensitivity, RoHS compliance, and regulatory classifications, indicating equivalent electrical performance.

Q: What factors should determine which part to select?

A: Selection should be based on available inventory, required PCB height specification, and mechanical clearance constraints. Both parts provide identical environmental performance and regulatory compliance.

Q: Why do the two parts have different base product numbers?

A: Base product numbers ELM5-9 and ELM5-2 identify different design variants within the ELM 5 series. The difference reflects the height specification variation (0.940" vs. 0.910"), while maintaining compatibility across the core mechanical and electrical parameters.

Q: Are packaging specifications identical between the substitute parts?

A: Both parts are supplied in Bag packaging format, providing equivalent handling and storage characteristics.
