Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-796642-9 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Number of positions: 19
• Header type: Male pins, shrouded (4 side)
• Mounting type: Through hole, vertical orientation
• Termination style: Solder
• Pitch tolerance: 0.197" (5.00mm) nominal or 0.200" (5.08mm) within mechanical compatibility
• Voltage rating: Minimum 300 V UL
• Current rating: Minimum 15 A UL
• Material flammability: UL94 V-0
• RoHS compliance: ROHS3 Compliant
• Insulation height: 0.472" (12.00mm)
• Contact mating finish: Tin

Substitute Parts Identified:

1. Phoenix Contact 1755671 – Exact pitch match (5.00mm), active product status, meets all electrical and mechanical parameters
2. Phoenix Contact 1755901 – Pitch variant (5.08mm), active product status, meets all electrical and mechanical parameters with higher voltage rating
3. Assmann WSW Components A-TB500-OQ19CV – Exact pitch match (5.00mm), active product status, meets all electrical and mechanical parameters with higher current rating

All three substitute parts maintain the 19-position configuration, vertical through-hole mounting, solder termination, and UL94 V-0 flammability rating required for direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1755671 is the primary substitute for the TE Connectivity 1-796642-9. This part maintains exact pitch specification (5.00mm), identical mechanical configuration, and active product status. All three substitute parts are ROHS3 compliant and UL94 V-0 rated, ensuring regulatory compliance for applications requiring the original component.

Phoenix Contact 1755901 serves as an alternative substitute with a 5.08mm pitch variant. While this represents a minor pitch deviation (0.08mm), the part maintains all other critical parameters and is suitable for applications where mechanical tolerance permits the pitch variation. This part offers higher IEC voltage rating (630 V) compared to the original specification.

Assmann WSW Components A-TB500-OQ19CV provides an additional substitute option with exact pitch matching (5.00mm) and enhanced current capacity (20 A UL versus 15 A UL on the original). This part is active and fully compliant with ROHS3 and UL94 V-0 requirements. The extended operating temperature range (-40°C ~ 115°C) provides additional thermal margin compared to the original specification.

All three substitute parts are currently in active production status, ensuring long-term availability and supply chain continuity. Selection between substitutes should be based on specific application requirements regarding current capacity, pitch tolerance, and thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1755901 be used as a direct replacement despite the 5.08mm pitch specification?

A: Phoenix Contact 1755901 features a 5.08mm pitch compared to the original 5.00mm specification. This 0.08mm difference represents a 0.16% deviation. Compatibility depends on the mechanical tolerance of the mating connector or application circuit board. Verify that the receiving connector or PCB footprint accommodates the 5.08mm pitch before selection.

Q: What is the significance of the contact tail length difference between the original part and Phoenix Contact substitutes?

A: The TE Connectivity 1-796642-9 and Assmann WSW A-TB500-OQ19CV both feature 0.138" (3.50mm) contact tail length, while Phoenix Contact 1755671 and 1755901 feature 0.154" (3.90mm) tail length. This difference affects solder joint depth and PCB hole engagement. Verify that the application PCB design accommodates the longer tail length for Phoenix Contact parts.

Q: Are all substitute parts suitable for the same voltage and current applications?

A: All substitute parts meet or exceed the original 300 V UL and 15 A UL specifications. Phoenix Contact 1755671 and 1755901 are rated at 12 A UL, which is below the original 15 A specification. Assmann WSW A-TB500-OQ19CV is rated at 20 A UL, exceeding the original specification. For applications requiring the full 15 A capacity, Assmann WSW A-TB500-OQ19CV is the appropriate selection.

Q: What is the difference between IEC and UL current ratings on the substitute parts?

A: Phoenix Contact 1755671 specifies 12 A IEC and 12 A UL. Phoenix Contact 1755901 specifies 12 A IEC and 12 A UL. These ratings represent different international standards. IEC (International Electrotechnical Commission) and UL (Underwriters Laboratories) ratings may differ based on testing methodology and safety margins. For applications requiring UL compliance, use the UL current rating as the limiting specification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All three substitute parts—Phoenix Contact 1755671, Phoenix Contact 1755901, and Assmann WSW A-TB500-OQ19CV—are ROHS3 compliant. The original TE Connectivity 1-796642-9 is also ROHS3 compliant. This ensures compatibility with RoHS-regulated applications and supply chains.

Q: What is the operating temperature range for Phoenix Contact substitutes?

A: Operating temperature specifications are not provided for Phoenix Contact 1755671 and 1755901 in the available data. The original TE Connectivity 1-796642-9 operates from -40°C to 110°C. Assmann WSW A-TB500-OQ19CV operates from -40°C to 115°C. Contact Phoenix Contact directly for operating temperature specifications if thermal performance is critical to the application.

Q: Can the Assmann WSW A-TB500-OQ19CV be used in applications originally designed for the TE Connectivity part?

A: Yes. The Assmann WSW A-TB500-OQ19CV maintains exact pitch (5.00mm), identical contact tail length (3.50mm), and identical insulation height (12.00mm) as the original TE Connectivity 1-796642-9. The part exceeds the original current specification (20 A versus 15 A) and extends the operating temperature range to 115°C. This part is suitable for direct substitution in applications designed for the original component.
