Engineering Selection Recommendations

5-146250-2 (TE Connectivity) is the primary substitute for new designs and production applications. This part maintains active product status, carries RoHS Compliance certification, and operates within the required temperature and flammability specifications. The LCP insulation material provides enhanced thermal and chemical resistance compared to standard thermoplastic alternatives.

4-103322-0-02 (TE Connectivity) is functionally compatible but carries discontinued status at DiGi Electronics and does not meet RoHS compliance requirements. This part is suitable only for legacy system maintenance or applications where RoHS compliance is not mandated.

Both substitute parts exhibit minor dimensional variations in contact length and insulation height relative to the TSW-102-14-F-D. These variations remain within acceptable tolerances for standard through-hole PCB applications with 0.100" (2.54mm) pitch spacing.

Frequently Asked Questions (FAQ)

Q: Can 5-146250-2 be used as a direct replacement for TSW-102-14-F-D in new production?

A: Yes. Both parts share identical mating pitch (0.100"), position count (4), row configuration (2), and fastening type (Push-Pull). The 5-146250-2 maintains UL94 V-0 flammability rating and RoHS Compliance, meeting standard production requirements.

Q: What are the key dimensional differences between these parts?

A: Contact length post differs by 0.015" (0.39mm), and insulation height differs by 0.010" (0.25mm). These variations do not affect mechanical fit in standard through-hole PCB designs with 0.100" (2.54mm) pitch spacing.

Q: Why does 4-103322-0-02 show discontinued status?

A: This part is discontinued at DiGi Electronics but remains functionally equivalent. Discontinuation reflects supplier inventory decisions rather than technical obsolescence. Availability through alternative distributors may vary.

Q: Are there compliance differences between the substitute parts?

A: Yes. The 5-146250-2 is RoHS Compliant, while 4-103322-0-02 is RoHS non-compliant. For applications requiring RoHS certification, 5-146250-2 is the appropriate selection.

Q: How do contact finish specifications affect substitution?

A: The TSW-102-14-F-D uses gold mating contacts (3.00µin), while substitutes use tin or tin-lead (100.0µin). Both finishes provide adequate corrosion resistance for standard applications. Gold plating offers superior long-term reliability in high-reliability or aerospace applications.

Q: What is the operating temperature difference between parts?

A: TSW-102-14-F-D operates -55°C to 125°C, while substitutes operate -65°C to 105°C. The TSW-102-14-F-D provides higher maximum temperature capability. For applications exceeding 105°C, the TSW-102-14-F-D is required.
