Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EM30MSD is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 2-position (1 + 1 Power) plug and receptacle architecture
• Shell Size: Insert size 30 with matching mechanical envelope
• Termination Method: Crimp and screw termination capability
• Fastening Mechanism: Bayonet lock coupling system
• Electrical Ratings: Current capacity (1A, 200A) and voltage withstand (250VAC/DC, 1500VAC/DC)
• Environmental Sealing: IP68 ingress protection classification
• Temperature Range: -40°C to 105°C operational limits
• Material Compliance: RoHS compliance and PBT shell material

The substitute part EM30MSD(04) maintains full electrical and mechanical compatibility with the main part number while offering active product status and improved packaging (Tray format).

Parameter Comparison

Engineering Selection Recommendations

The EM30MSD(04) is the direct active equivalent for the obsolete EM30MSD. Both parts share identical electrical specifications, mechanical dimensions, and environmental ratings. The primary distinction is product lifecycle status: EM30MSD(04) maintains active manufacturing status with current availability, while the original EM30MSD is obsolete.

Selection of EM30MSD(04) is supported by:

• Full electrical and mechanical parameter equivalence
• Active product status ensuring long-term supply chain continuity
• RoHS compliance certification maintained across both variants
• Identical contact materials, finishes, and thickness specifications
• Tray packaging format suitable for automated assembly processes

Frequently Asked Questions (FAQ)

Q: Can EM30MSD(04) be used as a direct replacement for EM30MSD?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters including connector configuration, shell size, termination method, fastening mechanism, current and voltage ratings, and environmental sealing. The primary difference is product status: EM30MSD(04) is active while EM30MSD is obsolete.

Q: What are the key compatibility criteria for this connector family?

A: Substitution within this connector family requires matching: 2-position (1 + 1 Power) configuration, shell size 30, crimp and screw termination, bayonet lock fastening, 1A/200A current capacity, 250VAC/DC and 1500VAC/DC voltage ratings, IP68 sealing, and -40°C to 105°C operating temperature range.

Q: Does packaging format affect electrical or mechanical performance?

A: No. The packaging difference between bulk and tray formats does not affect connector electrical specifications, mechanical dimensions, or performance characteristics. Packaging selection is determined by assembly process requirements and inventory management practices.

Q: Are there orientation differences between the main part and substitute?

A: The EM30MSD(04) includes keyed orientation specification, whereas the main part does not specify orientation. This represents an enhancement in the substitute part that ensures correct mating alignment without affecting backward compatibility.

Q: What compliance certifications apply to both parts?

A: Both EM30MSD and EM30MSD(04) maintain RoHS compliance status and Moisture Sensitivity Level 1 (Unlimited) classification, suitable for unrestricted storage and handling conditions.
