Substitute Part Grouping Explanation

The TE Connectivity AMP Connectors part number 796638-6 qualifies as a direct substitute based on the following critical parameters:

Electrical Compatibility: Both parts maintain 15A (UL) and 300V (UL) current and voltage ratings
Mechanical Compatibility: Identical 6-position configuration with 0.200" (5.08mm) pitch spacing
Form Factor: Both feature 90° right-angle orientation with male pins and 4-side shrouding
Mounting: Through-hole solder termination on identical 0.138" (4.60mm) contact tail length
Regulatory Compliance: Both achieve UL94 V-0 flammability rating and RoHS compliance
Insulation Height: Functionally equivalent dimensions (8.61mm vs 8.36mm) within acceptable tolerance for PCB layout

The primary difference lies in housing material composition (PBT vs PA66) and contact finish (Gold vs Tin), neither of which affects functional interchangeability in standard applications.

Engineering Selection Recommendations

Both the Phoenix Contact 1748248 and TE Connectivity 796638-6 are active production components with full RoHS compliance and UL94 V-0 certification. Selection between these parts should be based on:

Supply Chain Availability: Phoenix Contact 1748248 has 1032 units in stock; TE Connectivity 796638-6 has 7259 units available
Material Specification Requirements: PBT housing (Phoenix Contact) offers superior chemical resistance; PA66 housing (TE Connectivity) provides equivalent mechanical performance in standard industrial environments
Contact Finish Preference: Gold plating (Phoenix Contact) provides enhanced corrosion resistance; tin plating (TE Connectivity) is suitable for standard applications
Operating Temperature Range: TE Connectivity specifies -40°C to 110°C; Phoenix Contact does not specify this parameter but maintains equivalent UL ratings

Both parts meet identical electrical and mechanical substitution criteria for standard industrial control applications.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 796638-6 directly replace Phoenix Contact 1748248 on existing PCBs?

A: Yes. Both parts share identical pitch (5.08mm), contact tail length (4.60mm), and through-hole mounting footprint. No PCB redesign is required.

Q: What is the difference between PBT and PA66 housing materials?

A: PBT (polybutylene terephthalate) offers superior chemical and moisture resistance. PA66 (polyamide) provides equivalent mechanical strength and thermal performance for standard industrial applications. Both achieve UL94 V-0 flammability rating.

Q: Are the electrical ratings identical?

A: Yes. Both parts are rated 15A (UL) and 300V (UL). The Phoenix Contact part also specifies 12A (IEC) and 400V (IEC), which are not provided for the TE Connectivity equivalent.

Q: Does the 0.01" (0.25mm) difference in insulation height affect compatibility?

A: No. This dimensional variance is within standard manufacturing tolerance and does not impact PCB layout or connector mating.

Q: What is the significance of the contact finish difference?

A: Gold plating (Phoenix Contact) provides superior corrosion resistance in harsh environments. Tin plating (TE Connectivity) is suitable for standard industrial applications. Both finishes ensure reliable electrical contact.

Q: Are both parts RoHS compliant?

A: Yes. Phoenix Contact 1748248 is RoHS Compliant; TE Connectivity 796638-6 is ROHS3 Compliant. Both meet current regulatory requirements.

Q: Can these parts be used interchangeably in new designs?

A: Yes. Both parts meet identical functional, electrical, and mechanical specifications for 6-position, 5.08mm pitch terminal block header applications with 90° right-angle orientation.
