TE Connectivity 174254-1 DIN Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 174254-1 is a 32-position DIN plug connector with male pins, gold-plated contacts, and through-hole solder termination. This backplane connector operates across the Eurocard series and is designed for PCB mounting applications requiring 1.5A current capacity per contact.

The 174254-1 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance where this connector type remains in use.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 174254-1 are identified based on the following critical parameters that determine functional compatibility:

Core Compatibility Parameters:

• Pitch: 0.100" (2.54mm) — maintains PCB footprint compatibility
• Mounting Type: Through Hole — ensures mechanical fit on existing PCB designs
• Termination: Solder — compatible with standard PCB assembly processes
• Contact Finish: Gold — maintains electrical performance and corrosion resistance
• Current Rating: 1.5A — meets or exceeds electrical load requirements
• Operating Temperature Range: Minimum -55°C to 105°C — supports specified thermal envelope
• Material Flammability Rating: UL94 V-0 — maintains fire safety compliance
• Insulation Material: Polyester Thermoplastic — ensures material compatibility

Substitution Logic: The identified substitute parts are Amphenol ICC (FCI) 8609 series connectors (86094327614755E1LF and 86094327624755E1LF). These parts share identical pitch, mounting type, termination method, contact finish, current rating, and flammability rating. While these substitutes feature 48 total positions with 32 positions loaded (versus the 174254-1's 32 positions all loaded), they maintain functional equivalence for applications requiring 32-position connectivity. The substitutes operate across an extended temperature range (-55°C to 125°C) and carry active product status with RoHS compliance, providing improved supply chain availability and regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution:

The Amphenol ICC (FCI) parts 86094327614755E1LF and 86094327624755E1LF are functionally equivalent to the TE Connectivity 174254-1 based on electrical and mechanical parameters. Both substitute parts maintain the required 0.100" pitch, 1.5A current rating, gold contact finish, UL94 V-0 flammability rating, and polyester thermoplastic insulation. Through-hole solder termination is identical across all three parts.

Compliance Considerations:

The substitute parts carry active product status and RoHS compliance, providing regulatory alignment for new designs and ongoing production. The 174254-1's obsolete status and RoHS non-compliance status indicate this part is no longer manufactured or supported by TE Connectivity. Selection of the Amphenol ICC alternatives ensures access to current manufacturing processes and supply chain continuity.

Thermal Performance:

The substitute parts operate across an extended temperature range (-55°C to 125°C) compared to the 174254-1 (-55°C to 105°C). This extended range provides additional thermal margin for applications operating at elevated temperatures.

Packaging Differences:

The 86094327614755E1LF is supplied in tray packaging, while the 86094327624755E1LF is supplied in bag packaging. Selection between these two substitutes depends on procurement and assembly process requirements.

Connector Style Difference:

The 174254-1 is a plug connector (Q/2 style), while the substitute parts are header connectors (R/2 style). This difference reflects the connector's mating interface role. Plug connectors mate with receptacle connectors, while header connectors mate with plug connectors. PCB design and mating connector selection must account for this distinction.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 8609 series connectors directly replace the TE Connectivity 174254-1 on existing PCBs?

A: Direct PCB replacement requires verification of the mating connector type. The 174254-1 is a plug connector designed to mate with a receptacle. The Amphenol ICC substitutes are header connectors designed to mate with a plug. If the existing PCB design uses a receptacle connector, the header substitute will not mate with it. PCB layout and mating connector compatibility must be confirmed before substitution.

Q: What is the difference between the two Amphenol ICC substitute parts?

A: The parts 86094327614755E1LF and 86094327624755E1LF are electrically and mechanically identical. The only difference is packaging: 86094327614755E1LF is supplied in tray packaging, while 86094327624755E1LF is supplied in bag packaging. Selection depends on procurement volume and assembly process requirements.

Q: Why do the substitute parts have 48 total positions when the 174254-1 has 32 positions?

A: The Amphenol ICC 8609 series connectors are designed with 48 total position capacity but are loaded with 32 positions to match the 174254-1 functionality. This design approach allows a single connector platform to serve multiple position requirements. For applications requiring exactly 32 positions, the 32 loaded positions provide the necessary connectivity.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both Amphenol ICC substitute parts (86094327614755E1LF and 86094327624755E1LF) are RoHS compliant. The original TE Connectivity 174254-1 is RoHS non-compliant. Selection of RoHS-compliant substitutes ensures regulatory alignment with current environmental directives.

Q: What is the operating temperature difference between the main part and substitutes?

A: The 174254-1 operates from -55°C to 105°C. The Amphenol ICC substitutes operate from -55°C to 125°C. The 20°C extended upper temperature range in the substitutes provides additional thermal margin for high-temperature applications.

Q: Can I use these connectors interchangeably in my design?

A: Interchangeability depends on the complete connector system design. The pitch (0.100"), current rating (1.5A), contact finish (gold), and termination method (solder) are identical, ensuring electrical and mechanical compatibility at the contact level. However, the connector style difference (plug versus header) and row configuration difference (2 rows versus 3 rows) require verification against the mating connector and PCB layout specifications.

Q: What certifications do these connectors carry?

A: All three connectors carry UL94 V-0 flammability rating and use polyester thermoplastic insulation. The substitute parts carry RoHS compliance and active product status, while the 174254-1 is RoHS non-compliant and obsolete.
