Engineering Selection Recommendations

The TE Connectivity 5-146257-2 is the direct substitute for the obsolete 104350-2 based on the following engineering criteria:

Mechanical and Electrical Equivalence: The substitute part maintains identical specifications for all critical mating parameters, including position count, pitch spacing, contact geometry, and electrical ratings. The through-hole mounting configuration and breakaway header design are preserved.

Product Status Advantage: The 5-146257-2 holds active product status, ensuring continued availability and manufacturing support. The obsolete status of the 104350-2 necessitates transition to an active equivalent for ongoing production and supply chain reliability.

Compliance Enhancement: The substitute part achieves RoHS compliance, whereas the main part is RoHS non-compliant. This represents an improvement in regulatory alignment for applications subject to RoHS requirements.

Material Specification: The substitute employs Liquid Crystal Polymer (LCP) insulation material in place of thermoplastic. Both materials maintain the UL94 V-0 flammability rating and support the same operating temperature range of -65°C to 105°C.

Contact Finish Consideration: The substitute part features tin-plated posts rather than tin-lead plating. Both finishes are compatible with solder termination processes and maintain the gold-plated mating contacts specified in the original design.

Termination Compatibility: The main part supports both press-fit and solder termination, while the substitute supports solder termination only. For applications utilizing solder termination exclusively, this represents no functional limitation.

Frequently Asked Questions (FAQ)

Q: Can the 5-146257-2 be used as a direct replacement for the 104350-2 in existing designs?

A: Yes. The 5-146257-2 maintains identical mechanical and electrical specifications for all critical parameters including position count, pitch spacing, contact dimensions, current rating, and operating temperature range. The connector will interface with existing mating components without modification.

Q: What is the difference between the insulation materials used in these parts?

A: The 104350-2 uses thermoplastic insulation, while the 5-146257-2 uses Liquid Crystal Polymer (LCP). Both materials achieve UL94 V-0 flammability rating and support the identical operating temperature range of -65°C to 105°C. LCP offers enhanced dimensional stability and chemical resistance compared to standard thermoplastic.

Q: Does the change from tin-lead to tin plating on the posts affect solderability?

A: No. Both tin-lead and tin finishes are compatible with standard solder processes. Tin plating is widely used in modern connector manufacturing and provides equivalent solderability characteristics.

Q: Why is the voltage rating not specified for the 5-146257-2?

A: The voltage rating specification is not provided in the substitute part documentation. The main part specifies 30VAC. For applications requiring voltage rating confirmation, contact the manufacturer directly.

Q: Is the 5-146257-2 available in the same packaging as the 104350-2?

A: The 5-146257-2 is supplied in bulk packaging, whereas the 104350-2 packaging specification is not detailed in the provided documentation. Packaging format should be confirmed with the supplier based on specific procurement requirements.

Q: What is the significance of the RoHS compliance difference?

A: The 5-146257-2 is RoHS compliant, meeting the Restriction of Hazardous Substances directive requirements. The 104350-2 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the substitute part provides regulatory alignment.

Q: Are there any limitations when substituting the 104350-2 with the 5-146257-2?

A: The primary consideration is termination method. The 104350-2 supports both press-fit and solder termination, while the 5-146257-2 supports solder termination only. If press-fit termination is required, alternative solutions must be evaluated.

Q: How do the current ratings compare between these parts?

A: Both parts maintain a 3A current rating, ensuring equivalent electrical performance in applications designed for the original 104350-2 specification.
