TE Connectivity AMP Connectors 796637-8 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 796637-8 is an 8-position terminal block header with male pins, shrouded on four sides, featuring a 0.200" (5.08mm) vertical pitch and through-hole solder termination. This component operates at 15 A (UL) and 300 V (UL) with an operating temperature range of -40°C to 110°C. The part is manufactured from polyamide (PA66) nylon 6/6 housing with copper alloy contacts and tin mating finish. The 796637-8 maintains active product status and is RoHS compliant with MSL 1 rating.

Equivalent and substitute parts are necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit mechanical or electrical parameter variations within acceptable tolerances. Substitute parts must maintain compatibility with the 8-position configuration, vertical orientation, solder termination, and electrical ratings specified for the application.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0395311008 be used as a direct replacement for the TE Connectivity 796637-8?

A: Yes. The 0395311008 maintains identical 5.08mm pitch, 8-position vertical configuration, solder termination, and through-hole mounting. Both parts operate at 15 A (UL) and 300 V (UL) with UL94 V-0 flammability rating and RoHS compliance. Operating temperature range of the 0395311008 (-40°C to 105°C) covers the critical lower threshold of the original specification (-40°C to 110°C). No PCB layout modification is required.

Q: What is the difference between 5.00mm and 5.08mm pitch, and can they be used interchangeably?

A: The pitch is the center-to-center distance between adjacent pin positions. A 5.00mm pitch differs from 5.08mm by 0.08mm per position. For an 8-position header, this results in a cumulative difference of approximately 0.56mm across the entire component width. Interchangeability depends on PCB design tolerance. If the PCB footprint is designed for 5.08mm spacing, a 5.00mm component will not align properly. Conversely, if the PCB is designed for 5.00mm spacing, a 5.08mm component will not fit. PCB layout verification is required before substituting parts with different pitch values.

Q: Why do some substitute parts have lower current ratings (12 A) compared to the original 15 A specification?

A: Current rating is determined by contact material, contact geometry, and thermal design of the component. The Phoenix Contact 1755794 and 1755574 are rated at 12 A (UL), which is the maximum continuous current these components can safely carry without exceeding temperature limits. If the application requires 15 A continuous current, these parts are not suitable. However, if the actual application current is 12 A or less, these parts are acceptable substitutes.

Q: Can I use a substitute part with a higher current rating than the original?

A: Yes. The Phoenix Contact 1924363 is rated at 16 A (UL), which exceeds the original 15 A specification. A component with higher current rating can safely carry the original 15 A load. Higher current rating indicates greater thermal capacity and contact robustness, making it a suitable substitute for applications requiring the full 15 A specification.

Q: What does the operating temperature range mean, and why is it important for substitution?

A: Operating temperature range specifies the minimum and maximum ambient temperatures at which the component functions within its electrical specifications. The TE Connectivity 796637-8 operates from -40°C to 110°C. Substitute parts with a narrower range, such as -30°C to 105°C, cannot be used in applications requiring operation below -30°C. If the application requires -40°C operation, only substitutes with -40°C minimum temperature are acceptable.

Q: What is the significance of UL94 V-0 flammability rating?

A: UL94 V-0 is a flammability classification indicating that the housing material will not propagate flame and will self-extinguish within specified time limits when exposed to a direct flame. This rating is critical for safety-sensitive applications and regulatory compliance. All primary substitute parts maintain UL94 V-0 rating, ensuring equivalent fire safety performance.

Q: Are there any differences in contact material between the original part and substitutes?

A: The TE Connectivity 796637-8 uses copper alloy contacts, while most Molex and some Phoenix Contact substitutes use brass contacts. Both materials provide adequate electrical conductivity and corrosion resistance for terminal block applications. Brass contacts are functionally equivalent to copper alloy contacts for this application category. Contact material differences do not affect substitution suitability.

Q: What does RoHS compliance mean, and why do all substitutes maintain this status?

A: RoHS (Restriction of Hazardous Substances) compliance indicates that the component does not contain lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, or polybrominated diphenyl ethers above specified thresholds. RoHS compliance is a regulatory requirement in many markets. All substitute parts maintain RoHS compliance (either RoHS Compliant or ROHS3 Compliant status), ensuring equivalent regulatory compliance.

Q: What is Moisture Sensitivity Level (MSL), and why is it MSL 1 for all parts?

A: MSL indicates the sensitivity of a component to moisture absorption during storage and handling. MSL 1 (Unlimited) means the component has no moisture sensitivity restrictions and can be stored indefinitely without special humidity control. All parts in this comparison maintain MSL 1 rating, indicating equivalent storage and handling requirements.

Q: Can I substitute a part with different contact tail length?

A: Contact tail length affects solder joint formation and PCB hole engagement. The original 796637-8 has 0.138" (3.50mm) contact tail length, while substitutes range from 0.130" to 0.157". Shorter tail lengths (0.130") may result in reduced solder joint strength on thick PCBs, while longer tail lengths (0.154" to 0.157") provide better engagement on standard PCBs. Contact tail length variation is acceptable within the range 0.130" to 0.157" for standard PCB thicknesses (0.062" to 0.093"). Verify PCB thickness compatibility before substituting parts with significantly different tail lengths.

Q: What is the difference between "Through Hole" and "Solder" mounting types?

A: "Through Hole" indicates the component is inserted through holes in the PCB and soldered from the opposite side. "Solder" mounting type in the On Shore Technology parts indicates surface-mount or direct solder termination. The EDSTLZ955/8 and OSTOQ085450 are listed with "Solder" mounting type, which may indicate different assembly requirements compared to standard through-hole components. Verify assembly process compatibility before substituting these parts.

Q: Which substitute part offers the best availability?

A: The Phoenix Contact 1755794 offers the highest inventory availability with 36,949 units in stock. The Molex 0395311008 provides the second-highest availability with 13,407 units. Both parts are suitable primary substitutes for the TE Connectivity 796637-8 with identical 5.08mm pitch and equivalent electrical specifications.
