Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1544545-1 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Tab width: 0.110" (2.79mm)
• Tab thickness: 0.020" (0.51mm)
• Tab length: 0.264" (6.70mm)
• Overall length: 0.551" (14.00mm)
• Insulation diameter: 0.118" (3.00mm)

Electrical Compatibility Parameters:

• Wire gauge range: 17-24 AWG
• Gender: Female
• Termination method: Crimp
• Contact material: Brass
• Insulation classification: Non-Insulated

Regulatory & Environmental Parameters:

• RoHS3 compliance
• MSL rating: 1 (Unlimited)
• ECCN classification: EAR99
• HTSUS code: 8536.90.4000

Substitute parts must maintain identical values across all mechanical and electrical parameters. Variations in packaging format (Tape & Reel versus Cut Tape) do not affect functional equivalence. Product status differences (Last Time Buy versus Active) indicate availability but do not disqualify substitution.

Parameter Comparison

Engineering Selection Recommendations

The 1544545-3 is a direct functional equivalent to the 1544545-1 for all electrical and mechanical applications. Both parts share identical dimensional specifications, wire gauge compatibility, and contact material composition. The primary distinction is product status: the 1544545-1 is designated Last Time Buy, while the 1544545-3 maintains Active status, ensuring ongoing availability.

The 1544545-3 is packaged in Cut Tape (CT) format, whereas the 1544545-1 is supplied in Tape & Reel (TR) format. This packaging difference does not affect functional performance and reflects only the distribution method. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

The 1544545-3 specifies a tin contact finish, whereas the 1544545-1 contact finish is not specified in the provided data. Both parts utilize brass as the base contact material and are suitable for identical crimp termination applications with 17-24 AWG wire.

For new designs and production continuity, the 1544545-3 is the appropriate selection due to its Active product status and confirmed availability.

Frequently Asked Questions (FAQ)

Q: Can the 1544545-3 be used as a direct replacement for the 1544545-1 in existing assemblies?

A: Yes. The 1544545-3 is mechanically and electrically equivalent to the 1544545-1. All dimensional parameters, wire gauge ratings, and contact specifications are identical. The parts are interchangeable in all applications where the 1544545-1 was originally specified.

Q: What is the significance of the Last Time Buy status on the 1544545-1?

A: Last Time Buy designation indicates that the 1544545-1 is no longer in active production and existing inventory represents the final available stock. The 1544545-3 is the recommended alternative for future procurement and new designs.

Q: Does the packaging difference between Tape & Reel and Cut Tape affect performance?

A: No. Packaging format is a distribution and handling specification only. It does not affect the electrical or mechanical performance of the terminal. The choice between Tape & Reel and Cut Tape depends on assembly process requirements and volume needs.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1544545-1 and 1544545-3 are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: What wire gauges are compatible with these terminals?

A: Both parts are rated for 17-24 AWG wire gauges. Crimp termination must be performed using tooling specified for this wire gauge range and the 0.110" (2.79mm) tab width.

Q: Is there a difference in contact finish between the two parts?

A: The 1544545-3 specifies a tin contact finish. The 1544545-1 contact finish is not specified in the available data. Both parts use brass as the base contact material. The tin finish on the 1544545-3 provides corrosion resistance and is standard for this connector series.

Q: Can these terminals be used with insulated wire?

A: These are non-insulated terminals. They are designed for use with bare wire or wire with insulation stripped to the crimp point. The insulation diameter specification (0.118" / 3.00mm) indicates the maximum wire insulation diameter that can be accommodated at the terminal entry point.
