Engineering Selection Recommendations
The V7-6B39D8-348-1 is classified as an active product with current manufacturing support, whereas the AM50055D43-A is obsolete. For new designs or long-term production requirements, the Honeywell V7-6B39D8-348-1 provides supply chain continuity and ongoing manufacturer support.
Both parts carry identical ECCN (EAR99) and HTSUS (8536.50.7000) classifications, confirming regulatory equivalence for export and tariff purposes. Both maintain MSL 1 moisture sensitivity rating, indicating no special handling requirements during storage or assembly.
Selection between these parts should be based on:
- Supply Availability: The Honeywell part maintains active production status
- Regulatory Compliance: Both parts meet identical export control and tariff classifications
- Mechanical Compatibility: Verify mounting footprint and termination alignment with existing PCB or chassis design
- Electrical Performance: Confirm current and voltage ratings meet application requirements
Frequently Asked Questions (FAQ)
Q: Can the V7-6B39D8-348-1 directly replace the AM50055D43-A in existing assemblies?
A: Direct replacement requires verification of mechanical mounting dimensions, termination pin spacing, and actuator engagement geometry. While both parts share SPST switching functionality and quick connect termination, physical compatibility must be confirmed against the original design specifications.
Q: What is the significance of the MSL 1 rating on both parts?
A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without special moisture control measures. Both parts can be stored and handled using standard component storage practices without requiring dry-pack or desiccant packaging.
Q: Why is the AM50055D43-A listed as obsolete?
A: Obsolete status indicates the manufacturer has discontinued production. The part remains available through existing inventory channels, but long-term supply cannot be guaranteed. The Honeywell V7-6B39D8-348-1 provides a path to sustained supply for applications requiring this switch type.
Q: Are there any compliance differences between these parts?
A: Both parts share identical ECCN (EAR99) and HTSUS (8536.50.7000) classifications, confirming equivalent regulatory treatment for export control and tariff purposes. No compliance barriers exist to substitution from a regulatory standpoint.
Q: What parameters must match for successful substitution?
A: Critical matching parameters include circuit configuration (SPST-NC), current rating (minimum 100mA), voltage rating (125V AC / 30V DC minimum), actuator type (lever or roller), mounting type (chassis mount), and termination style (quick connect 0.250"). Operating temperature range (-25°C to 105°C) and reliability metrics (100,000 electrical cycles; 10,000,000 mechanical cycles) must also be met or exceeded.
