Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 0307760000 is determined by the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 4 positions at 0.200" (5.08mm) pitch to ensure PCB footprint compatibility
• Mating Orientation: 45° (135°) angle with board orientation must be preserved for connector alignment
• Mounting Type: Through-hole mounting is required for mechanical compatibility
• Current & Voltage Ratings: Substitute parts must meet or exceed the 15A / 150V electrical specifications
• Wire Gauge Compatibility: Wire termination must accommodate the specified conductor sizes
• Screw Thread & Torque: M2.5 screw thread with 0.4-0.5 Nm torque specification ensures mechanical interchangeability

The Weidmüller 9994550000 qualifies as a functional substitute based on matching position count, pitch, orientation, mounting type, and screw specifications. Differences in voltage rating (300V vs. 150V), wire gauge range (14-24 AWG vs. 12-22 AWG), and wire termination method (clamping yoke vs. leaf spring) represent enhanced or alternative capabilities rather than incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 9994550000 (Omnimate LM Series) is the designated substitute for the obsolete 0307760000 (MK Series). Selection is based on the following engineering criteria:

Mechanical Compatibility: Both parts share identical position count (4), pitch (5.08mm), mating orientation (45°), mounting type (through-hole), and screw specifications (M2.5, 0.4-0.5 Nm). PCB footprint compatibility is assured.

Electrical Adequacy: The substitute meets the original 15A current requirement and exceeds the 150V voltage specification with a 300V rating. Wire gauge overlap (14-22 AWG) covers the critical range of the original part (12-22 AWG).

Product Status & Availability: The 0307760000 is obsolete with no ongoing production. The 9994550000 is active and in production, ensuring long-term procurement viability and supply chain continuity.

Regulatory Compliance: Both parts share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and moisture sensitivity level (MSL 1). The substitute maintains compliance requirements of the original design.

Enhanced Performance: The substitute provides extended operating temperature range (-50°C to 120°C vs. -20°C to 100°C) and improved voltage margin, making it suitable for applications requiring broader environmental tolerance.

Frequently Asked Questions (FAQ)

Q: Can the 9994550000 be used as a direct replacement for the 0307760000 on existing PCBs?

A: Yes. Both parts have identical pitch (5.08mm), position count (4), mating orientation (45°), and mounting type (through-hole). The PCB footprint and mounting holes are compatible. Screw specifications (M2.5, 0.4-0.5 Nm) are identical, ensuring mechanical interchangeability.

Q: What is the difference in wire termination between these parts?

A: The 0307760000 uses screw-leaf spring termination with wire guard. The 9994550000 uses screw-clamping yoke termination with tension sleeve. Both are screw-based termination methods. The wire gauge overlap (14-22 AWG) ensures compatibility for standard applications.

Q: Does the higher voltage rating of the 9994550000 affect circuit design?

A: No. The substitute's 300V rating exceeds the original 150V specification, providing additional safety margin. This does not require circuit redesign and is suitable for the same voltage applications.

Q: Are there packaging differences between these parts?

A: The 0307760000 is listed with no specified packaging. The 9994550000 is supplied in bulk packaging. Verify packaging requirements with your procurement process.

Q: What is the temperature operating range difference?

A: The 0307760000 operates from -20°C to 100°C. The 9994550000 operates from -50°C to 120°C. The substitute provides a wider temperature envelope, suitable for applications requiring extended thermal tolerance.

Q: Are both parts RoHS compliant?

A: The 0307760000 product status does not specify RoHS compliance. The 9994550000 is RoHS Compliant. Verify RoHS requirements for your application.

Q: Can I use the 9994550000 for 12 AWG wire applications?

A: The 9994550000 wire gauge range is 14-24 AWG. The original 0307760000 supports 12-22 AWG. For 12 AWG wire applications, verify that the 14 AWG minimum of the substitute meets your current-carrying requirements at the specified 15A rating.
