Key Parameters

Substitute Part Grouping Explanation

Substitution between the 111783-7 and 5104338-7 is established through strict equivalence of core electrical and mechanical parameters. Both connectors maintain identical specifications for the following critical substitution criteria:

Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (34)
• Number of rows (2)
• Mating pitch (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Connection style (Board to Cable/Wire)
• Contact length - mating (0.240" / 6.10mm)
• Insulation color (Black)
• Keying slot feature

The 5104338-7 represents an active production equivalent that fulfills the same functional role while providing enhanced specifications in contact finish, insulation material, operating temperature range, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 5104338-7 is the active equivalent substitute for the obsolete 111783-7. Both connectors share identical core mechanical and electrical specifications for mating interface, position count, pitch, and mounting configuration, establishing direct functional interchangeability.

Product Status Consideration: The 111783-7 carries obsolete status, while the 5104338-7 maintains active production status. For new designs and ongoing procurement, the 5104338-7 is the appropriate selection.

Compliance Advantage: The 5104338-7 achieves RoHS compliance, whereas the 111783-7 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulatory requirements.

Enhanced Specifications: The 5104338-7 provides documented operating temperature range (-65°C ~ 105°C), UL94 V-0 flammability rating, and specified current rating (1A per contact), offering greater technical transparency compared to the 111783-7.

Contact Finish Enhancement: The 5104338-7 features increased mating contact finish thickness (15.0µin versus 5.11µin) and offers gold-palladium as an alternative finish option, providing improved durability characteristics.

Termination Compatibility: The 5104338-7 supports both kinked pin and solder termination methods, while the 111783-7 specifies solder termination only. This expanded termination capability in the substitute part does not restrict compatibility with solder-only applications.

Frequently Asked Questions (FAQ)

Q: Are the 111783-7 and 5104338-7 directly interchangeable?

A: Yes. Both connectors maintain identical specifications for connector type, contact type, position count (34), row configuration (2 rows), mating pitch (0.100" / 2.54mm), row spacing, mounting type (through hole), shrouding (4-wall), and contact length. The mating interface and board footprint are equivalent, supporting direct substitution.

Q: What is the primary reason to transition from 111783-7 to 5104338-7?

A: The 111783-7 is classified as obsolete, while the 5104338-7 maintains active production status. Additionally, the 5104338-7 achieves RoHS compliance and provides enhanced specifications including documented operating temperature range and flammability rating.

Q: Does the packaging difference affect compatibility?

A: No. The 111783-7 packaging specification is not provided in the technical data, while the 5104338-7 is supplied in tube packaging. Packaging affects handling and storage logistics but does not impact electrical or mechanical compatibility.

Q: Are there differences in contact finish that affect performance?

A: The 5104338-7 features increased mating contact finish thickness (15.0µin) compared to the 111783-7 (5.11µin), providing enhanced durability. The 5104338-7 also offers gold-palladium as an alternative to gold finish. Both finishes support equivalent electrical performance for standard applications.

Q: What is the significance of the RoHS compliance difference?

A: The 5104338-7 is RoHS compliant, while the 111783-7 is RoHS non-compliant. RoHS compliance is mandatory for applications and markets subject to RoHS regulations. The 5104338-7 eliminates compliance risk for regulated applications.

Q: Does the termination method difference affect substitution?

A: The 5104338-7 supports kinked pin and solder termination, while the 111783-7 specifies solder termination only. For applications using solder termination exclusively, this difference does not restrict substitution. The expanded termination capability of the 5104338-7 provides additional design flexibility.

Q: What inventory considerations apply to these parts?

A: The 111783-7 has 886 pieces in stock, while the 5104338-7 has 15,712 pieces in stock. The significantly higher inventory level for the 5104338-7 supports improved procurement availability and lead time performance.

Q: Are the operating temperature specifications compatible?

A: The 111783-7 does not specify an operating temperature range. The 5104338-7 specifies -65°C ~ 105°C. For applications requiring operation within this temperature range, the 5104338-7 provides documented thermal performance. For applications with different thermal requirements, the unspecified range of the 111783-7 does not establish a limitation.
