Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 170728-1 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Terminal Type: Circular
• Stud/Tab Size: M5 Stud
• Wire Gauge: 8 AWG
• Termination Method: Crimp
• Insulation: Non-Insulated
• Contact Material: Copper
• Contact Finish: Tin
• Mounting Type: Free Hanging (In-Line)

The Phoenix Contact 3240089 satisfies all primary substitution criteria. Secondary dimensional variations (thickness, width, and length) remain within acceptable tolerances for M5 stud applications and do not affect functional compatibility. Both parts maintain equivalent electrical and mechanical performance for 8 AWG wire termination on M5 studs.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3240089 is the direct functional equivalent for the obsolete TE Connectivity 170728-1. Selection of the Phoenix Contact part is supported by the following factors:

Product Status: The Phoenix Contact 3240089 maintains active product status, ensuring continued availability and supply chain reliability. The TE Connectivity 170728-1 is obsolete and subject to inventory depletion.

Regulatory Compliance: Both parts are ROHS3 compliant and carry identical ECCN and HTSUS classifications, confirming equivalent regulatory standing. The Phoenix Contact part provides defined REACH status (REACH Unaffected), whereas the TE Connectivity part shows vendor-undefined REACH status.

Electrical and Mechanical Equivalence: Both terminals accommodate 8 AWG wire gauge with M5 stud mounting, identical termination method (crimp), and matching contact material and finish specifications. Dimensional variations are secondary and do not affect functional performance in M5 stud applications.

Moisture and Environmental Ratings: Both parts carry MSL Rating 1 (Unlimited), indicating equivalent environmental performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 3240089 directly replace the TE Connectivity 170728-1 in existing assemblies?

A: Yes. Both terminals are functionally equivalent for M5 stud applications with 8 AWG wire. The primary electrical and mechanical parameters are identical. Dimensional differences (thickness, width, length) are minor and do not affect compatibility with M5 stud mounting or 8 AWG wire termination.

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

A: Substitution is determined by equivalence in terminal type (circular), stud size (M5), wire gauge (8 AWG), termination method (crimp), insulation type (non-insulated), contact material (copper), contact finish (tin), and mounting type (free hanging in-line). All these parameters are identical between the two parts.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant with identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications. The Phoenix Contact part specifies REACH Unaffected status, while the TE Connectivity part shows vendor-undefined REACH status. Both carry MSL Rating 1 (Unlimited).

Q: What is the packaging difference between these parts?

A: The TE Connectivity 170728-1 packaging is not specified in available documentation. The Phoenix Contact 3240089 is supplied in bulk packaging. Packaging format does not affect terminal functionality or compatibility.

Q: Why is the TE Connectivity 170728-1 classified as obsolete?

A: Obsolescence is a manufacturer product lifecycle designation indicating the part is no longer in active production. The Phoenix Contact 3240089 maintains active status and serves as the current equivalent for new procurement and system maintenance.

Q: Are the dimensional differences between these parts significant?

A: Dimensional variations (thickness 0.047" vs. 0.043", width 0.472" vs. 0.394", length 0.945" vs. 0.827") are minor and do not affect functional performance in M5 stud applications. Both terminals accommodate identical wire gauge and stud size specifications.

Q: What is the inventory status of these parts?

A: The TE Connectivity 170728-1 shows 1,081 pieces in stock as new original inventory. The Phoenix Contact 3240089 shows 2,971 pieces in stock as new original inventory. Inventory levels are subject to change based on current procurement activity.
