Substitute Part Grouping Explanation

Substitution of the Weidmüller 995288 is determined by the following critical parameters:

Position Count & Pitch: Both main and substitute parts must maintain 8 positions at 0.295" (7.50mm) pitch to ensure PCB footprint compatibility
Mating Orientation: Horizontal with board orientation is required for mechanical fit
Electrical Ratings: Current and voltage ratings must meet or exceed the original specification (15 A, 300 V minimum)
Wire Gauge Compatibility: Acceptable wire gauge range must accommodate the original 12-26 AWG specification
Mounting Configuration: Through-hole mounting type must be preserved
Screw Thread Standard: M3 thread specification ensures mechanical compatibility with existing tooling and assembly processes

The Assmann WSW Components A-TB750-VI08H satisfies all critical substitution criteria while offering enhanced electrical performance and active product status.

Engineering Selection Recommendations

The Assmann WSW Components A-TB750-VI08H is a direct substitute for the Weidmüller 995288 based on the following engineering criteria:

Mechanical Compatibility: Both components share identical pitch (7.50mm), position count (8), and through-hole mounting configuration, ensuring PCB footprint compatibility without layout modifications.

Electrical Performance: The Assmann substitute meets all electrical requirements with equivalent voltage rating (300 V) and exceeds current capacity (16 A vs. 15 A), providing operational margin.

Product Status & Compliance: The Assmann part is actively manufactured and ROHS3 compliant, addressing the obsolescence of the original Weidmüller component. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

Temperature Operating Range: The substitute provides an extended operating temperature range (-30°C ~ 105°C) compared to the original (-20°C ~ 100°C), supporting broader application environments.

Wire Termination Compatibility: Both components utilize M3 screw-based termination, maintaining assembly process compatibility despite differences in clamping mechanism design (Clamping Yoke vs. Rising Cage Clamp).

Frequently Asked Questions (FAQ)

Q: Can the Assmann A-TB750-VI08H be used as a direct replacement for the Weidmüller 995288 on existing PCBs?

A: Yes. Both components share identical pitch (7.50mm), position count (8), and through-hole mounting specifications. No PCB layout modifications are required for mechanical substitution.

Q: Are there differences in wire termination between these components?

A: Yes. The Weidmüller 995288 uses a Clamping Yoke with Tension Sleeve, while the Assmann A-TB750-VI08H uses a Rising Cage Clamp. Both are screw-based M3 termination systems. Assembly procedures may differ; consult component datasheets for specific torque and installation requirements.

Q: Does the Assmann substitute support the same wire gauge range?

A: The Assmann substitute supports 12-28 AWG, which encompasses the original 12-26 AWG specification. The wider range provides additional flexibility for wire selection.

Q: What is the significance of the Assmann part being ROHS3 compliant while the original is not applicable?

A: The Weidmüller 995288 predates current RoHS regulations (obsolete status). The Assmann A-TB750-VI08H meets ROHS3 compliance, making it suitable for applications requiring adherence to current environmental and material restriction standards.

Q: Are there any temperature operating range considerations for substitution?

A: The Assmann substitute operates across -30°C ~ 105°C, compared to the original -20°C ~ 100°C. This extended range supports applications in more extreme thermal environments without performance degradation.

Q: What is the current inventory status for these components?

A: The Weidmüller 995288 has 1143 pieces in stock (obsolete status). The Assmann A-TB750-VI08H has 1083 pieces in stock and is actively manufactured, ensuring long-term availability.
