Substitute Part Grouping Explanation
The 521848-3 qualifies as a direct substitute for the 521848-1 based on identical electrical and mechanical parameters. Both parts share the following critical specifications that determine substitution compatibility:
- Tab width of 0.250" (6.35mm)
- Tab thickness of 0.032" (0.81mm)
- Wire gauge rating of 14-18 AWG
- Female gender configuration
- Crimp termination method
- Mating end insulation
- Free hanging in-line mounting type
- Overall length of 1.366" (34.70mm)
- Insulation diameter range of 0.110" ~ 0.170" (2.79mm ~ 4.32mm)
- Brass contact material
- White color
The primary distinction between these parts is product status and packaging configuration, not functional or dimensional characteristics.

Frequently Asked Questions (FAQ)
Q: Can the 521848-3 be used as a direct replacement for the 521848-1 in existing designs?
A: Yes. The 521848-3 provides complete functional and dimensional equivalence. All electrical and mechanical parameters, including tab width, thickness, wire gauge rating, insulation type, and mounting configuration, are identical between the two parts.
Q: What is the primary reason to transition from 521848-1 to 521848-3?
A: The 521848-1 is classified as obsolete product status, while the 521848-3 is active. This transition ensures long-term supply availability and eliminates procurement risk associated with discontinued components.
Q: Are there any compliance differences between these parts?
A: Both parts are RoHS compliant and carry EAR99 export classification. The 521848-1 is specifically ROHS3 compliant, while the 521848-3 is RoHS compliant. Both meet regulatory requirements for their respective applications.
Q: What is the packaging difference between these parts?
A: The 521848-1 packaging is not specified in available documentation. The 521848-3 is supplied in bulk packaging, which is standard for production environments requiring multiple units.
Q: Are there any wire gauge or insulation diameter restrictions?
A: Both parts accommodate 14-18 AWG wire with insulation diameters ranging from 0.110" to 0.170" (2.79mm to 4.32mm). These specifications are identical and impose no additional constraints on substitution.
Q: What is the MSL rating for these connectors?
A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity limitations during storage, handling, or assembly processes.
