Part Overview

The TE Connectivity AMP Connectors 1-104353-8 is a rectangular connector header designed for through-hole, right-angle mounting applications. This connector features 50 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing, supporting board-to-board or cable interconnections. The part operates within a temperature range of -65°C to 105°C and carries a current rating of 3A at 30VAC.

The 1-104353-8 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for legacy systems utilizing this connector specification.

• Row spacing (mating): 0.100" (2.54mm)
• Mounting type: Through hole, right angle
• Connector type: Header configuration
• Contact type: Male pin
• Shrouding: Unshrouded

Electrical Compatibility:

• Contact material: Copper alloy
• Contact finish (mating): Gold
• Current rating: Equal to or greater than 3A
• Voltage rating: Equal to or greater than 30VAC
• Operating temperature range: Must encompass or exceed -65°C to 105°C

Material & Compliance:

• Insulation material: Thermoplastic or equivalent dielectric
• Material flammability: UL94 V-0 or equivalent

The 3M 929667-04-25-I meets the mechanical and electrical core requirements for substitution, with the exception of specific parameter variations noted in the comparison table below.

Engineering Selection Recommendations

The 3M 929667-04-25-I serves as a functional substitute for the obsolete TE Connectivity 1-104353-8 based on matching mechanical and primary electrical specifications. The following factors support this substitution:

Advantages of the 3M 929667-04-25-I:

• Active product status ensures ongoing availability and supply chain continuity
• RoHS compliance meets current regulatory requirements for new designs and manufacturing
• Identical pitch spacing, row configuration, and mounting orientation ensure mechanical interchangeability
• Gold-plated mating contacts and copper alloy base material maintain electrical performance
• UL94 V-0 flammability rating matches the original specification

Considerations for Implementation:

• The 3M part operates at a minimum temperature of -40°C, compared to the TE part's -65°C minimum. Applications requiring operation below -40°C require evaluation against actual system requirements.
• The 3M part carries a current rating of 2.5A, which is 0.5A lower than the TE part's 3A rating. Circuit designs operating at or near 3A must be reassessed for the 2.5A limit.
• Contact post finish differs (gold on 3M versus tin-lead on TE). Both finishes are suitable for solder termination; however, soldering parameters may require adjustment.
• Insulation height and contact length dimensions show minor variations. PCB layout and mating connector clearances must be verified for compatibility.
• The 3M part's voltage rating is not specified in available documentation. Applications requiring explicit 30VAC rating confirmation should obtain detailed specifications from the manufacturer.

Frequently Asked Questions (FAQ)

Q: Can the 3M 929667-04-25-I be used as a direct replacement for the TE Connectivity 1-104353-8 in existing designs?

A: The 3M part provides mechanical and functional compatibility for most applications. However, three factors require evaluation: (1) minimum operating temperature of -40°C versus -65°C on the original part, (2) current rating of 2.5A versus 3A, and (3) unspecified voltage rating on the 3M part. Designs operating within -40°C to 105°C and at or below 2.5A are compatible without modification.

Q: What are the key mechanical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: 50-position count, 2-row configuration, 0.100" (2.54mm) pitch spacing, 0.100" (2.54mm) row spacing, through-hole right-angle mounting, unshrouded header design, male pin contacts, and square contact shape. Any deviation in these parameters eliminates substitution compatibility.

Q: How do the contact finish specifications differ between these parts?

A: The TE Connectivity part features gold-plated mating contacts (30.0µin thickness) with tin-lead plated posts. The 3M part features gold-plated mating contacts (10.0µin thickness) with gold-plated posts. Both configurations support solder termination; the thinner gold plating on the 3M part remains within industry standards for contact durability and electrical performance.

Q: Does the 3M 929667-04-25-I meet RoHS compliance requirements?

A: Yes, the 3M 929667-04-25-I is RoHS compliant. The original TE Connectivity part is RoHS non-compliant. For new designs or manufacturing processes subject to RoHS regulations, the 3M part satisfies compliance requirements.

Q: What is the significance of the insulation material difference?

A: The TE Connectivity part uses thermoplastic insulation material. The 3M part uses polybutylene terephthalate (PBT) with polyester and glass filler. Both materials are thermoplastic-based and provide equivalent dielectric properties. The glass-filled PBT on the 3M part offers enhanced mechanical strength and thermal stability, making it suitable for the same application range.

Q: Are there any PCB layout considerations when substituting the 3M part?

A: Minor dimensional variations exist: contact length (mating) differs by 0.005", contact length (post) differs by 0.025", and insulation height differs by 0.023". These variations are within typical manufacturing tolerances for standard 2.54mm pitch connectors. PCB footprints designed for 2.54mm pitch headers accommodate both parts without modification. Verify mating connector clearances if tight spacing is present in the design.

Q: What should be done if the application requires operation below -40°C?

A: The 3M 929667-04-25-I is not rated for operation below -40°C. Applications requiring -65°C operation must either source the original TE Connectivity part from inventory or identify alternative connector solutions rated for the full temperature range. Consult with the connector manufacturer for low-temperature alternatives.

Q: Is the 3M part suitable for applications requiring 3A current?

A: The 3M 929667-04-25-I carries a maximum current rating of 2.5A. Applications designed for 3A operation must be reassessed. If the actual operating current is below 2.5A, the part is suitable. If sustained operation at 3A is required, the original TE Connectivity part or an alternative rated for 3A must be used.
