Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 1776263-3

The 1776263-3 is the preferred substitute for the obsolete 796605-3. Both components are manufactured by TE Connectivity AMP Connectors within the Buchanan series, ensuring design continuity and mechanical compatibility. The 1776263-3 maintains identical pitch spacing (5.00mm), position count (3), mounting configuration, and electrical ratings (10 A, 300 V). The primary difference is the termination style variation from rising cage clamp to leaf spring with wire guard, which represents an acceptable engineering substitution. The 1776263-3 is currently in active production status with ROHS3 compliance, addressing the regulatory limitations of the obsolete 796605-3. Wire gauge compatibility exists within the overlapping range of 16-22 AWG. The operating temperature range of -40°C to 105°C is suitable for applications not requiring the extended low-temperature performance of the original part.

Secondary Substitutes: On Shore Technology ED130/3DS and OSTTH Series

The ED130/3DS and OSTTH030100/OSTTH030160 terminal block plugs provide alternative sourcing from On Shore Technology Inc. All three components maintain the critical 3-position, 5.00mm pitch configuration with free-hanging in-line mounting. The ED130/3DS supports the full 14-22 AWG wire gauge range matching the original 796605-3 and includes UL94 V-0 flammability rating. The OSTTH series (OSTTH030100 and OSTTH030160) extends the operating temperature range to -40°C to 115°C and provides enhanced wire gauge compatibility (0.34-1.5mm²). All On Shore Technology substitutes are ROHS3 compliant and currently in active production. The OSTTH030160 variant offers the highest inventory availability (9876 pieces) and maintains blue housing color matching the original specification.

Compliance Considerations

The 796605-3 is RoHS non-compliant. All substitute parts (1776263-3, ED130/3DS, OSTTH030100, OSTTH030160) are ROHS3 compliant, meeting current regulatory requirements for new designs and procurement. Applications requiring RoHS compliance must transition to one of the listed substitutes.

Frequently Asked Questions (FAQ)

Q: Can the 1776263-3 directly replace the 796605-3 in existing designs?

A: The 1776263-3 maintains mechanical and electrical compatibility with the 796605-3 across all critical parameters: 3-position configuration, 5.00mm pitch, 10 A current rating, 300 V voltage rating, M2.6 screw size, and free-hanging in-line mounting. The termination style differs (leaf spring with wire guard versus rising cage clamp), but both are screw-type termination methods suitable for the same unshrouded header interfaces. Wire gauge compatibility exists within the overlapping 16-22 AWG range. Applications operating within -40°C to 105°C temperature limits can use the 1776263-3 as a direct substitute.

Q: What are the wire gauge compatibility constraints when substituting the 796605-3?

A: The original 796605-3 accepts 14-22 AWG (0.3-2mm²) wire gauges. The 1776263-3 accepts 16-24 AWG (0.2-1.4mm²), creating an overlapping range of 16-22 AWG. Applications using 14 AWG or 23-24 AWG wire must use alternative substitutes. The ED130/3DS supports the full 14-22 AWG range. The OSTTH030100 and OSTTH030160 support 14-22 AWG with mm² range of 0.34-1.5mm², providing compatibility for most applications.

Q: Are there temperature range limitations when substituting the 796605-3?

A: The original 796605-3 operates from -55°C to 155°C. The 1776263-3 operates from -40°C to 105°C, representing a reduced temperature envelope. Applications requiring operation below -40°C or above 105°C cannot use the 1776263-3. The ED130/3DS operates from -30°C to 105°C. The OSTTH030100 and OSTTH030160 extend the upper limit to 115°C (-40°C to 115°C), suitable for applications requiring extended high-temperature performance within the -40°C to 115°C range.

Q: What is the difference between the OSTTH030100 and OSTTH030160 variants?

A: Both OSTTH030100 and OSTTH030160 share identical electrical and mechanical specifications: 3-position, 5.00mm pitch, 300 V rating, M2.6 screw size, -40°C to 115°C operating temperature, and 0.34-1.5mm² wire gauge range. The primary difference is housing color: OSTTH030100 features black housing, while OSTTH030160 features blue housing matching the original 796605-3 color specification. The OSTTH030160 also provides significantly higher inventory availability (9876 pieces versus 770 pieces).

Q: Are all substitute parts RoHS compliant?

A: Yes. The original 796605-3 is RoHS non-compliant. All substitute parts (1776263-3, ED130/3DS, OSTTH030100, OSTTH030160) are ROHS3 compliant, meeting current regulatory requirements for electronic component procurement and new product designs.

Q: What contact material differences exist among the substitutes?

A: The 796605-3, 1776263-3, OSTTH030100, and OSTTH030160 use brass contact material. The ED130/3DS uses copper beryllium contact material, which provides enhanced electrical conductivity and spring characteristics. Both brass and copper beryllium contacts are suitable for the specified 10 A current rating and 300 V voltage rating. Contact mating finish varies: 796605-3 and 1776263-3 use tin finish, while ED130/3DS and OSTTH series use nickel finish.

Q: Can the OSTTH series parts be used in applications originally designed for the 796605-3?

A: The OSTTH030100 and OSTTH030160 maintain compatibility across all primary parameters: 3-position configuration, 5.00mm pitch, 300 V voltage rating, free-hanging in-line mounting, and screw-type termination with M2.6 screws. Wire gauge compatibility exists within the 14-22 AWG overlapping range. Operating temperature compatibility depends on application requirements: OSTTH series supports -40°C to 115°C, which covers most industrial applications. The primary consideration is wire entry orientation, which is not specified for OSTTH parts; applications requiring 90° wire entry should confirm compatibility with the specific unshrouded header design.

Q: What inventory considerations should guide substitute part selection?

A: Current inventory levels are: 796605-3 (900 pieces), 1776263-3 (1356 pieces), ED130/3DS (710 pieces), OSTTH030100 (770 pieces), and OSTTH030160 (9876 pieces). The OSTTH030160 offers the highest availability for immediate procurement. The 1776263-3 provides the closest design continuity as a TE Connectivity AMP Connectors product within the Buchanan series. Selection should balance inventory availability with design continuity and compliance requirements.
