Substitute Part Grouping Explanation

Substitution eligibility for the 691373500007B is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

Number of positions: 7
Pitch: 0.200" (5.08mm)
Plug wire entry orientation: 180°
Termination method: Screw-pressure clip
Mounting configuration: Free hanging (in-line)
Flammability rating: UL94 V-0
Housing material family: Polyamide/Nylon

Acceptable Variation Parameters:

Current rating: UL rating of 15-16 A is acceptable
Voltage rating: UL rating of 300 V or higher is acceptable
Wire gauge range: Overlap of 12-24 AWG with substitute part range

Engineering Selection Recommendations

Both the Würth Elektronik 691373500007B and Phoenix Contact 1777332 are active production components with full RoHS and export compliance (EAR99). Selection between these parts should be based on:

Würth Elektronik 691373500007B: Select when WR-TBL Series 373B compatibility is required or when the higher wire gauge capacity (up to 3.3mm²) is necessary for applications using larger conductor sizes.

Phoenix Contact 1777332: Select when COMBICON FRONT-MSTB series integration is preferred or when the extended wire gauge range (12-30 AWG) provides additional flexibility for smaller gauge applications. The IEC current rating of 12 A provides additional specification data for international applications.

Both parts support identical pitch, position count, termination method, and mounting configuration. The 1 A difference in UL current rating (16 A vs. 15 A) and the 0.09mm difference in insulation height are within acceptable engineering tolerances for standard terminal block applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1777332 be used as a direct replacement for the Würth Elektronik 691373500007B?

A: Yes. Both parts share identical pitch (5.08mm), position count (7), wire entry orientation (180°), termination method (screw-pressure clip), and mounting type (free hanging in-line). Electrical ratings and mechanical dimensions are within acceptable tolerances.

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

A: The Würth part supports 12-24 AWG (0.2-3.3mm²), while the Phoenix Contact part supports 12-30 AWG (0.2-2.5mm²). The Würth part accommodates larger conductors up to 3.3mm², whereas the Phoenix Contact part extends the lower gauge range to 30 AWG. Selection depends on the specific wire sizes used in your application.

Q: Are there packaging differences between these parts?

A: Yes. The Würth Elektronik 691373500007B is supplied in Tray packaging (671 units in stock), while the Phoenix Contact 1777332 is supplied in Bulk packaging (972 units in stock). Packaging format may affect procurement, handling, and storage requirements.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant and classified as EAR99 for export control. The Würth part carries ROHS3 certification, while the Phoenix Contact part carries standard RoHS certification. Both achieve UL94 V-0 flammability rating and are suitable for applications requiring equivalent safety compliance.

Q: What is the difference in screw specifications?

A: The Würth part uses M2.6 screws with 0.45 Nm torque specification, while the Phoenix Contact part uses M2.5 screws with 0.5-0.6 Nm torque specification. These minor differences do not affect functional compatibility but should be noted during assembly and maintenance procedures.
