Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1544500-3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Tab Width: 0.250" (6.35mm)
• Tab Thickness: 0.032" (0.81mm)
• Wire Gauge: 17-22 AWG
• Gender: Female
• Termination: Crimp
• Insulation: Non-Insulated
• Contact Material: Brass
• Mounting Type: Free Hanging (In-Line)

The substitute part 1989879-1 meets all mandatory matching parameters. Dimensional variations in tab length and overall length remain within acceptable tolerances for quick connect receptacle applications. The substitute maintains equivalent electrical and mechanical performance for the specified wire gauge and connection interface.

Parameter Comparison

Engineering Selection Recommendations

The 1989879-1 serves as the active equivalent for the obsolete 1544500-3. Both components share identical critical electrical and mechanical specifications for 17-22 AWG quick connect applications. The substitute part maintains RoHS compliance with ROHS3 certification, exceeding the original RoHS Compliant status. Both components carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity constraints.

The 1989879-1 is currently in active production with substantial inventory availability (14,355 pieces), ensuring reliable supply for new designs and replacement applications. The transition from the PRONER series to the Fastin-Faston series reflects TE Connectivity's product line evolution while maintaining functional equivalence.

Dimensional differences in overall length (0.748" versus 0.677") and tab length (0.299" versus 0.303") are within acceptable tolerances for quick connect receptacle applications and do not affect electrical performance or mating characteristics with standard 0.250" quick connect male tabs.

Frequently Asked Questions (FAQ)

Q: Can the 1989879-1 directly replace the 1544500-3 in existing applications?

A: Yes. Both components share identical tab width (0.250"), tab thickness (0.032"), wire gauge rating (17-22 AWG), and contact material (brass). The substitute maintains the same crimp termination method and free-hanging mounting configuration.

Q: What is the significance of the series change from PRONER to Fastin-Faston?

A: The series designation reflects TE Connectivity's product portfolio organization. The Fastin-Faston series represents the current active product line for quick connect terminals. Functional specifications remain equivalent between series for this connector type.

Q: Are there packaging differences between the main part and substitute?

A: The 1544500-3 packaging is not specified in available data. The 1989879-1 is supplied in Cut Tape (CT) packaging, which is standard for high-volume terminal distribution.

Q: Do both parts meet current regulatory requirements?

A: Yes. The 1544500-3 is RoHS Compliant. The 1989879-1 is ROHS3 Compliant, representing the current RoHS directive iteration. Both components carry identical MSL Rating 1 (Unlimited) and EAR99 ECCN classification.

Q: What is the impact of the insulation diameter specification difference?

A: The 1544500-3 specifies insulation diameter as 0.118" (3.00mm). The 1989879-1 specifies a range of 0.091" ~ 0.130" (2.31mm ~ 3.30mm). This range encompasses the original specification, ensuring compatibility with the same wire insulation dimensions.

Q: Is the 1989879-1 suitable for new design applications?

A: Yes. The 1989879-1 is classified as Active product status, indicating current manufacturing and full technical support availability. This part is appropriate for both replacement and new design applications requiring 0.250" quick connect female crimp terminals rated for 17-22 AWG wire.
