Key Parameters

Substitute Part Grouping Explanation

Substitution of the 104430-1 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Header, Breakaway)
• Number of positions (3)
• Pitch spacing (0.100" / 2.54mm)
• Mounting configuration (Through Hole, Right Angle)
• Contact dimensions (mating length, post length, insulation height)

Electrical Compatibility:

• Contact type (Male Pin)
• Current rating (3A minimum)
• Operating temperature range (-65°C ~ 105°C)
• Material flammability rating (UL94 V-0)

Material & Finish Compatibility:

• Contact material (Copper Alloy)
• Insulation material (Thermoplastic)
• Contact finish on mating surface (Gold)

The substitute part 5-102974-3 maintains full equivalence across all mechanical and electrical parameters. Differences exist only in product status (Active vs. Obsolete), RoHS compliance status, and contact finish on the post termination (Tin vs. Tin-Lead).

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5-102974-3 is a direct functional equivalent to the obsolete 104430-1 across all critical mechanical and electrical parameters. Selection of the substitute part is supported by the following factors:

Product Status: The 5-102974-3 maintains active product status with confirmed inventory availability (1020 pcs), whereas the 104430-1 is obsolete. Active status ensures continued supply chain access and manufacturing support.

Compliance & Certifications: Both parts carry identical UL94 V-0 flammability ratings and operate within the same temperature range (-65°C ~ 105°C). The substitute part achieves RoHS compliance, whereas the main part does not. This represents an improvement in regulatory alignment for new designs or manufacturing transitions.

Termination Compatibility: The main part specifies Press-Fit and Solder termination options. The substitute part specifies Solder termination only. For applications utilizing solder termination, full compatibility is established. Applications requiring press-fit termination must evaluate alternative solutions.

Contact Finish: The substitute part uses Tin finish on the post (lead-free), compared to Tin-Lead on the main part. Both finishes are compatible with standard solder processes and PCB assembly workflows.

Mechanical & Electrical Equivalence: All dimensional parameters, contact configurations, current ratings, and voltage specifications are identical between the two parts, confirming direct substitution capability for board-to-board and cable interconnection applications.

Frequently Asked Questions (FAQ)

Q: Can the 5-102974-3 be used as a direct replacement for the 104430-1 in existing designs?

A: Yes, the 5-102974-3 is mechanically and electrically equivalent to the 104430-1 across all critical parameters. The connector maintains identical pitch spacing (0.100" / 2.54mm), position count (3), contact dimensions, current rating (3A), and operating temperature range (-65°C ~ 105°C). Direct substitution is supported for applications using solder termination.

Q: What is the difference in termination methods between these parts?

A: The 104430-1 supports both Press-Fit and Solder termination. The 5-102974-3 supports Solder termination only. If your application requires press-fit termination, the 5-102974-3 is not suitable. Confirm your assembly process before selecting the substitute part.

Q: Does the lead-free Tin finish on the 5-102974-3 affect compatibility with the original Tin-Lead finish?

A: No. Both Tin and Tin-Lead finishes are compatible with standard solder assembly processes. The Tin finish on the 5-102974-3 represents a lead-free alternative that meets modern manufacturing and environmental standards. Solder joint quality and reliability are equivalent between the two finishes.

Q: Why is the 104430-1 marked as obsolete?

A: The 104430-1 has been discontinued by TE Connectivity AMP Connectors. The 5-102974-3 is the active equivalent part within the AMPMODU Mod II series and is recommended for new designs and ongoing production requirements.

Q: Is the 5-102974-3 RoHS compliant?

A: Yes, the 5-102974-3 is RoHS compliant. The original 104430-1 is RoHS non-compliant. If your application or regulatory environment requires RoHS compliance, the 5-102974-3 satisfies this requirement.

Q: Are the contact dimensions identical between the two parts?

A: Yes. Both parts have identical mating contact length (0.318" / 8.08mm), post contact length (0.110" / 2.79mm), and insulation height (0.138" / 3.50mm). PCB footprints and mating interface dimensions are fully compatible.

Q: What is the current and voltage rating for the 5-102974-3?

A: The 5-102974-3 supports a current rating of 3A. The voltage rating is not specified in the available documentation. For applications requiring specific voltage ratings, refer to the original 104430-1 specification (30VAC) or contact the manufacturer for complete electrical specifications.

Q: Can I use the 5-102974-3 in temperature-sensitive applications?

A: Yes. The 5-102974-3 operates across the same temperature range as the 104430-1: -65°C to 105°C. Both parts are suitable for applications within this thermal envelope.
