HE1G-20MB Equivalent & Substitute Parts

Part Overview

The HE1G-20MB is an enabling switch manufactured by IDEC, classified as a pushbutton switch. This component is currently designated as obsolete, which necessitates identification of active equivalent parts for continued system support and procurement. The HE1G-20MB maintains a moisture sensitivity level of 1 (unlimited), indicating robust environmental tolerance. With 776 pieces in current inventory stock, transition to an active substitute part is required for long-term component availability and supply chain continuity.

Substitute Part Grouping Explanation

The HE1G-20MB belongs to the IDEC HE1G series of enabling switches. Substitution is based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Manufacturer: IDEC (same manufacturer maintains design consistency)
• Series: HE1G (same product line ensures mechanical and electrical compatibility)
• Component Type: Pushbutton Switch (functional category match)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental tolerance equivalence)

The substitute part HE1G-L20MB is classified as an active product within the same HE1G series, providing direct functional replacement capability. This substitution maintains electrical and mechanical compatibility while transitioning from an obsolete to an active product status.

Parameter Comparison

Engineering Selection Recommendations

Product Status Transition: The HE1G-20MB is classified as obsolete, making the HE1G-L20MB the appropriate active substitute. Both components share identical manufacturer origin (IDEC) and series designation (HE1G), ensuring design compatibility within the product line.

Compliance and Certification: The HE1G-L20MB carries EAR99 ECCN classification, indicating standard commercial export compliance. The HTSUS code 8536.50.9033 applies to electrical switches and switching apparatus. Both parts maintain MSL 1 (Unlimited) rating, confirming equivalent environmental tolerance.

Supply Chain Continuity: With 737 pieces of HE1G-L20MB in active inventory stock and bulk packaging availability, this substitute provides reliable long-term procurement capability. The transition from the obsolete HE1G-20MB to the active HE1G-L20MB ensures uninterrupted component supply for system maintenance and new production requirements.
