Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 995377 is determined by the following critical parameters:

Position count and pitch: Must maintain 6 positions at 0.300" (7.62mm) spacing to ensure PCB footprint compatibility
Mating orientation: Must be horizontal with board configuration for mechanical fit
Mounting method: Must support through-hole PCB mounting
Wire termination principle: Screw-based clamping systems are functionally interchangeable
Electrical ratings: Substitute must meet or exceed 15 A current and 300 V voltage specifications
Wire gauge accommodation: Must accept 12-26 AWG minimum range
Housing and contact materials: Polyamide (PA66) housing with copper alloy tin-plated contacts establish the baseline material compatibility

The Amphenol PCD ESGM06400 satisfies all substitution criteria through matching position count, pitch, orientation, mounting type, and material composition while providing enhanced electrical performance and extended operating temperature range.

Engineering Selection Recommendations

The Amphenol PCD ESGM06400 is the qualified substitute for the obsolete Weidmüller 995377. Selection is based on the following factors:

Product Status: The ESGM06400 maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete 995377.

Compliance and Certifications: The ESGM06400 is RoHS Compliant, meeting current regulatory requirements for electronic component manufacturing. The 995377 carries "Not applicable" RoHS status, reflecting its obsolete classification.

Electrical Performance: The ESGM06400 provides enhanced current capacity (17.5 A versus 15 A) and extended wire gauge accommodation (12-30 AWG versus 12-26 AWG), offering design margin for existing and future applications.

Operating Temperature Range: The ESGM06400 extends the operating envelope to -40°C ~ 110°C, compared to the 995377's -20°C ~ 100°C, supporting broader environmental deployment scenarios.

Mechanical and Electrical Compatibility: Both components maintain identical pitch, position count, mating orientation, mounting type, and housing/contact materials, ensuring direct PCB footprint compatibility and electrical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol PCD ESGM06400 be used as a direct replacement for the Weidmüller 995377 on existing PCBs?

A: Yes. Both components share identical pitch (0.300"/7.62mm), position count (6), mating orientation (horizontal with board), and through-hole mounting configuration. PCB footprints are mechanically compatible.

Q: What are the key differences between the two terminal blocks?

A: The ESGM06400 provides higher current capacity (17.5 A vs. 15 A), broader wire gauge support (12-30 AWG vs. 12-26 AWG), extended operating temperature range (-40°C to 110°C vs. -20°C to 100°C), and active product status with RoHS compliance. Wire termination mechanisms differ (rising cage clamp vs. clamping yoke with tension sleeve) but both employ screw-based clamping principles.

Q: Are the wire termination methods functionally equivalent?

A: Both employ screw-based clamping for wire retention. The 995377 uses a clamping yoke with tension sleeve, while the ESGM06400 uses a rising cage clamp. Both methods provide secure electrical connection and are suitable for the specified wire gauge ranges.

Q: What is the packaging difference between these parts?

A: The Weidmüller 995377 packaging is listed as unspecified. The Amphenol PCD ESGM06400 is supplied in Tray packaging.

Q: Does the ESGM06400 meet current regulatory requirements?

A: Yes. The ESGM06400 is RoHS Compliant, meeting current electronic component manufacturing regulations. The obsolete 995377 predates current compliance requirements.

Q: Can the ESGM06400 handle the same voltage and current as the 995377?

A: The ESGM06400 meets or exceeds all electrical specifications of the 995377. Both are rated for 300 V. The ESGM06400 provides 17.5 A capacity compared to the 995377's 15 A, ensuring compatibility with existing designs and providing additional performance margin.
