TE Connectivity AMP Connectors 104429-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 104429-2 is a rectangular connector header designed for through-hole, right-angle mounting applications. This connector features a 4-position configuration with 0.100" (2.54mm) pitch spacing and is classified as a board-to-board or cable connector with unshrouded, breakaway male pin contacts. The part is currently listed as obsolete, necessitating identification of equivalent substitute components for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 104429-2 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 4
• Number of Rows: 1
• Connector Type: Header, Breakaway
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Material Flammability Rating: UL94 V-0
• Insulation Color: Black

The Molex 0901210764 satisfies all mandatory matching parameters and is therefore classified as a direct equivalent substitute. Both connectors share identical mating pitch, position count, row configuration, contact type, mounting orientation, and fastening mechanism. Both maintain gold-plated mating contacts and UL94 V-0 flammability compliance with black insulation.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0901210764 is the direct equivalent substitute for the obsolete TE Connectivity 104429-2. Selection of the Molex substitute is supported by the following engineering factors:

Product Status: The TE Connectivity 104429-2 is classified as obsolete, making the active-status Molex 0901210764 the appropriate replacement for ongoing production and design requirements.

Compliance and Certifications: Both connectors maintain UL94 V-0 flammability compliance and identical ECCN and HTSUS classifications. The Molex substitute achieves ROHS3 compliance, providing enhanced regulatory alignment for modern applications compared to the non-compliant original part.

Functional Equivalence: The connectors share identical mating pitch (0.100"), position count (4), row configuration (1), contact type (male pin), mounting orientation (through-hole right-angle), and fastening mechanism (push-pull). Both feature gold-plated mating contacts and black insulation.

Physical Compatibility: Contact post dimensions (0.110" versus 0.114") and insulation height (0.138" versus 0.142") are within typical manufacturing tolerances for through-hole board mounting. Mating contact length variation (0.318" versus 0.266") reflects design differences between series but does not affect mating compatibility with standard receptacle connectors.

Material Considerations: The Molex substitute employs brass contact material with polyester glass-filled insulation, compared to copper alloy contacts with thermoplastic insulation in the original. Both material systems provide equivalent electrical performance and environmental resistance for the specified application categories.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0901210764 directly replace the TE Connectivity 104429-2 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (4), row configuration, contact type (male pin), mounting type (through-hole right-angle), and fastening mechanism (push-pull). The connectors are mechanically and electrically compatible for board-to-board and cable applications.

Q: What are the differences in contact dimensions between these two connectors?

A: The mating contact length differs (TE: 0.318" versus Molex: 0.266") and insulation height varies slightly (TE: 0.138" versus Molex: 0.142"). These dimensional variations reflect different design approaches between the AMPMODU Mod II and C-Grid III 90121 series but do not affect compatibility with standard receptacle connectors or through-hole board mounting.

Q: Does the Molex substitute meet RoHS requirements?

A: Yes. The Molex 0901210764 is ROHS3 compliant, whereas the original TE Connectivity 104429-2 is RoHS non-compliant. This represents an improvement in regulatory compliance for new designs and production.

Q: Are the contact materials equivalent between these connectors?

A: The contact materials differ (TE: copper alloy versus Molex: brass). Both materials provide equivalent electrical conductivity and corrosion resistance for standard applications. The gold plating on mating contacts is present in both connectors, ensuring consistent contact performance.

Q: What is the packaging difference between these parts?

A: The TE Connectivity 104429-2 packaging is not specified in available documentation. The Molex 0901210764 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are current and voltage ratings specified for the Molex substitute?

A: Current and voltage ratings are not provided in the Molex 0901210764 technical documentation. The original TE Connectivity 104429-2 specifies 3A current rating and 30VAC voltage rating. Consult Molex technical documentation or contact the manufacturer for complete electrical specifications of the substitute part.

Q: What is the moisture sensitivity level for both connectors?

A: Both connectors are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
