Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 1776263-4 serves as the active equivalent for the obsolete 796605-4 terminal block plug. Selection of the substitute part is based on the following engineering criteria:

Product Status Alignment: The 796605-4 is classified as obsolete, creating supply chain discontinuity. The 1776263-4 maintains active product status with current manufacturing and distribution support, ensuring long-term availability for production and field service requirements.

Electrical and Mechanical Compatibility: Both parts maintain identical electrical ratings (10 A at 300 V UL), connector geometry (4-position, 5.00mm pitch, 90° wire entry), mounting configuration (free hanging in-line), and contact specifications (brass with tin mating finish). The M2.6 screw interface and 11.00mm insulation height ensure mechanical interchangeability within the unshrouded header interface.

Termination Technology Difference: The 796605-4 employs rising cage clamp termination, while the 1776263-4 uses leaf spring termination with wire guard. Both termination methods are screw-actuated and compatible with the same wire gauge overlap range (16-22 AWG / 0.3-1.4mm²), supporting direct functional replacement for applications within this wire specification window.

Operating Temperature Consideration: The 796605-4 operates across -55°C to 155°C, while the 1776263-4 operates across -40°C to 105°C. Applications requiring operation below -40°C or above 105°C must retain the original 796605-4 specification or identify alternative solutions outside the Buchanan series.

Compliance Status: Both parts carry identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications. The 796605-4 is RoHS non-compliant, while the 1776263-4 carries "Not applicable" RoHS status. Applications subject to RoHS compliance requirements must evaluate the 1776263-4 status with the component supplier.

Frequently Asked Questions (FAQ)

Q: Can the 1776263-4 directly replace the 796605-4 in all applications?

A: Direct replacement is supported for applications using wire gauges within the overlapping range (16-22 AWG / 0.3-1.4mm²) and operating temperatures between -40°C and 105°C. Applications requiring operation outside this temperature range or using 14-15 AWG wire must retain the original 796605-4 or identify alternative solutions.

Q: What is the primary difference between the rising cage clamp and leaf spring termination styles?

A: The 796605-4 uses rising cage clamp termination, while the 1776263-4 uses leaf spring termination with wire guard. Both are screw-actuated and provide equivalent electrical performance within their specified wire gauge ranges. The leaf spring design in the 1776263-4 includes a wire guard feature for additional strain relief.

Q: Are the connector interfaces identical between the two parts?

A: Yes. Both parts maintain identical 4-position configuration, 0.197" (5.00mm) pitch spacing, 90° wire entry orientation, M2.6 screw size, and 0.433" (11.00mm) insulation height. The unshrouded header interface is mechanically and electrically compatible.

Q: What is the significance of the wire gauge range difference?

A: The 796605-4 accepts 14-22 AWG (0.3-2mm²), while the 1776263-4 accepts 16-24 AWG (0.2-1.4mm²). The overlapping range is 16-22 AWG (0.3-1.4mm²). Applications using 14-15 AWG wire require the original 796605-4. Applications using 23-24 AWG wire require the 1776263-4.

Q: Why is the 796605-4 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 1776263-4 represents the active Buchanan series equivalent, ensuring continued supply chain support and manufacturing availability.

Q: Are there packaging differences between the two parts?

A: The 796605-4 packaging is not specified in the available data. The 1776263-4 is supplied in bulk packaging. Packaging requirements should be confirmed with the component supplier based on production volume and logistics needs.

Q: Do both parts meet the same electrical safety standards?

A: Yes. Both parts carry identical UL ratings (10 A at 300 V), tin contact mating finish, and brass contact material. Both are classified as UL94 V-0 or equivalent for flammability (where specified), supporting equivalent electrical safety performance.

Q: What is the operating temperature overlap between the two parts?

A: The overlapping operating temperature range is -40°C to 105°C. The 796605-4 extends operation to -55°C and 155°C beyond this window. Applications requiring these extended temperature limits must use the original 796605-4.

Q: Are both parts RoHS compliant?

A: The 796605-4 is RoHS non-compliant. The 1776263-4 carries "Not applicable" RoHS status. Applications subject to RoHS compliance requirements should confirm the 1776263-4 status with the component supplier or TE Connectivity technical support.

Q: Can the screw torque specifications be used interchangeably?

A: The 796605-4 does not specify screw torque. The 1776263-4 specifies 0.34 Nm (3.0 Lb-In). For applications using the 1776263-4, apply the specified torque value. For the 796605-4, consult TE Connectivity technical documentation or the original equipment manufacturer specifications.
