Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 1766796 are grouped based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Number of positions: 4
• Header orientation: Vertical
• Type: Male pins, shrouded (4 side)
• Termination style: Solder
• Mounting type: Through hole
• Material flammability rating: UL94 V-0

Secondary Compatibility Factors:

• Pitch spacing (7.62mm primary; 5.08mm and 7.50mm as alternatives)
• Electrical ratings (current and voltage per IEC and UL standards)
• Contact tail length and insulation height
• RoHS and REACH compliance status

Substitutes are identified within the Weidmüller Omnimate SL series and Würth Elektronik WR-TBL Series 3114, which share the core mechanical and electrical architecture required for direct replacement or application-specific alternatives.

Parameter Comparison

Engineering Selection Recommendations

Direct Pitch-Matched Substitutes (7.62mm):

Weidmüller 1625270000 and Würth Elektronik 691311400104 are pitch-identical alternatives to the Phoenix Contact 1766796. Both maintain 0.300" (7.62mm) spacing, vertical orientation, and UL94 V-0 flammability compliance. The Weidmüller 1625270000 offers higher IEC voltage rating (800V vs. 630V) and equivalent UL ratings. The Würth Elektronik 691311400104 provides higher UL current capacity (20A vs. 15A) and ROHS3 compliance matching the original part.

Pitch-Variant Substitutes:

Weidmüller 1629150000 operates at 0.295" (7.50mm) pitch, introducing minimal spacing deviation while maintaining electrical equivalence and UL94 V-0 compliance. This part is suitable for applications where slight pitch tolerance is acceptable.

Weidmüller 1147200000 operates at 0.200" (5.08mm) pitch with higher current capacity (24A IEC, 18.5A UL). This substitute is applicable only when board layout accommodates reduced pitch spacing and higher current handling is required.

Compliance Considerations:

All substitute parts maintain UL94 V-0 flammability rating and active product status. The Phoenix Contact 1766796 and Würth Elektronik 691311400104 are both ROHS3 compliant. Weidmüller parts carry standard RoHS compliance. REACH status varies: Phoenix Contact and Würth Elektronik are unaffected; Weidmüller parts are unaffected except where noted.

Frequently Asked Questions (FAQ)

Q: Can Weidmüller 1625270000 directly replace Phoenix Contact 1766796?

A: Yes. Both parts share identical 7.62mm pitch, 4-position vertical configuration, male pin shrouded design, and solder termination. Electrical ratings are compatible for UL applications (15A, 300V). The Weidmüller part exceeds IEC ratings (18.5A, 800V vs. 12A, 630V).

Q: What is the impact of using Weidmüller 1147200000 with 5.08mm pitch?

A: The 5.08mm pitch reduces spacing between positions by 33% compared to the 7.62mm standard. This substitute is applicable only if PCB layout accommodates the reduced pitch. Electrical ratings are higher (24A IEC, 18.5A UL), making it suitable for higher-current applications within the same form factor.

Q: Are contact tail length differences significant?

A: Contact tail lengths vary: Phoenix Contact 1766796 (3.90mm), Weidmüller parts (3.20mm), and Würth Elektronik 691311400104 (4.00mm). These differences affect solder joint depth and PCB pad design. Shorter tails (3.20mm) require less through-hole depth; longer tails (4.00mm) provide greater solder volume. Verify PCB design compatibility before substitution.

Q: Which substitute offers the best current capacity?

A: Würth Elektronik 691311400104 provides the highest UL current rating at 20A (vs. 15A for the original). Weidmüller 1147200000 offers the highest IEC rating at 24A. Selection depends on whether IEC or UL standards apply to the application.

Q: Are all substitutes RoHS compliant?

A: Yes. Phoenix Contact 1766796 and Würth Elektronik 691311400104 are ROHS3 compliant. Weidmüller 1625270000, 1629150000, and 1147200000 are RoHS compliant. All meet environmental compliance requirements for current manufacturing standards.

Q: What is the difference between 7.62mm and 7.50mm pitch?

A: Weidmüller 1629150000 operates at 7.50mm (0.295") pitch versus the standard 7.62mm (0.300"). The 0.12mm difference per position accumulates to 0.36mm across four positions. This variant is suitable for applications with slight pitch tolerance but should be verified against specific PCB layout requirements.
