Substitute Part Grouping Explanation

Substitution between the main part 104074-4 and the alternative part 5-104074-4 is based on strict electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical dimensions and functional characteristics:

Key Parameters Determining Substitution:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (20 positions, 1 row)
• Mating pitch and contact dimensions (0.050" / 1.27mm pitch)
• Mounting orientation and termination method (Through Hole, Right Angle, Solder)
• Shrouding configuration (Shrouded - 2 Wall)
• Operating temperature range (-65°C ~ 105°C)
• Voltage rating (30VAC)
• Material flammability compliance (UL94 V-0)
• Contact material and finish specifications (Copper Alloy, Gold mating surface)

The substitute part 5-104074-4 maintains full compatibility with the original 104074-4 across all mechanical interfaces and electrical performance parameters. Differences exist only in post-manufacturing compliance status and contact finish post composition, which do not affect functional interchangeability in the specified applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 104074-4 and 5-104074-4 are active products from TE Connectivity AMP Connectors and are fully interchangeable for all specified applications. Selection between these parts should be based on the following criteria:

104074-4 Selection:

• Applications where Tin-Lead post finish is explicitly required by design specification
• Environments where REACH Affected status is acceptable or required
• Situations where RoHS compliance is not a design constraint

5-104074-4 Selection:

• Applications requiring RoHS Compliant components
• Designs where Tin post finish meets performance requirements
• Situations where higher inventory availability is advantageous
• New designs targeting modern compliance standards

Both parts maintain identical electrical performance, mechanical dimensions, and thermal operating characteristics. The substitute part 5-104074-4 provides enhanced regulatory compliance through RoHS certification while maintaining full functional equivalence. Contact finish post composition differs between the two parts (Tin-Lead versus Tin), but both finishes provide equivalent solder joint reliability and electrical performance at the specified 30VAC voltage rating and -65°C to 105°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Are the 104074-4 and 5-104074-4 mechanically interchangeable?

A: Yes. Both parts share identical mechanical dimensions, mounting configurations, and board interface specifications. The 20-position, single-row header with 0.050" (1.27mm) pitch, through-hole right-angle mounting, and shrouded 2-wall construction are identical across both part numbers.

Q: What is the difference between Tin-Lead and Tin post finishes?

A: The main part 104074-4 features Tin-Lead post finish, while the substitute 5-104074-4 features Tin post finish. Both finishes are applied at 150.0µin (3.81µm) thickness and provide equivalent solder joint reliability and electrical conductivity for the specified applications.

Q: Can I use 5-104074-4 in place of 104074-4 in existing designs?

A: Yes. The 5-104074-4 is fully compatible with all electrical and mechanical requirements of the 104074-4. The primary difference is enhanced RoHS compliance status. Designs currently using 104074-4 can transition to 5-104074-4 without modification.

Q: What does RoHS Compliant status mean for the 5-104074-4?

A: RoHS Compliant indicates that the 5-104074-4 meets the Restriction of Hazardous Substances directive, restricting the use of specific hazardous materials. This is relevant for applications in regulated markets, particularly in Europe and for manufacturers subject to RoHS requirements.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the 104074-4 and 5-104074-4 are specified for automotive applications, along with general purpose, medical, and telecommunications use. Both maintain UL94 V-0 material flammability rating and operate across the -65°C to 105°C temperature range required for automotive environments.

Q: What is the voltage rating for these connectors?

A: Both parts are rated for 30VAC. This voltage rating applies to the mating interface and must be observed in circuit design and application selection.

Q: How many positions does this header provide?

A: Both the 104074-4 and 5-104074-4 provide 20 positions in a single-row configuration with 0.050" (1.27mm) pitch spacing.

Q: What is the operating temperature range?

A: Both parts operate across -65°C to 105°C, suitable for industrial, automotive, medical, and telecommunications applications requiring extended temperature performance.

Q: What termination method is used?

A: Both parts use solder termination for through-hole PCB mounting. The solder pads are designed for standard wave or reflow soldering processes.

Q: Is the board guide feature present on both parts?

A: Yes. Both the 104074-4 and 5-104074-4 include board guide features to assist with proper alignment during assembly and mating operations.
