Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1528110000 is determined by the following critical parameters:

19-position configuration with 0.200" (5.08mm) pitch
Female socket contact type
180° free-hanging in-line mounting
Screw termination with M2.5 or compatible screw size
Wire gauge compatibility within 12-26 AWG (0.2-2.5mm²) minimum range
UL94 V-0 flammability rating
Operating temperature range of at least -40°C to 100°C
Electrical ratings meeting or exceeding UL 15A/300V minimum

The substitute parts listed below meet these core substitution criteria. Variations in contact material, housing material, screw torque specifications, and wire gauge upper limits do not preclude substitution when the minimum electrical and mechanical requirements are satisfied.

Engineering Selection Recommendations

Weidmüller 1943980000 – Direct manufacturer equivalent with active product status. Maintains identical pitch, position count, and mounting configuration. Offers enhanced current rating (20A UL vs. 15A) and expanded wire gauge compatibility (12-30 AWG vs. 12-26 AWG). RoHS compliant with MSL 1 rating. Recommended for applications requiring continued Weidmüller ecosystem compatibility.

TE Connectivity 1-796634-9 and 1-796635-9 – Active Buchanan series alternatives with identical mechanical and electrical core specifications. Both support 15A UL current and 300V UL voltage. Differ in housing color (green vs. black) and use phosphor bronze contacts with polyamide housing. Extended operating temperature range (-40°C to 110°C). ROHS3 compliant. Suitable for applications where TE Connectivity component standardization is preferred.

On Shore Technology OSTV8195151 – Active alternative with male pin configuration (vs. female sockets in main part). Supports 20A UL current and extended operating temperature (-40°C to 115°C). ROHS3 compliant. Wire gauge limited to 12-22 AWG. Use only when mating connector accepts male pins or when system redesign accommodates contact type change.

Frequently Asked Questions (FAQ)

Q: Can I use OSTV8195151 as a direct replacement for 1528110000?

A: OSTV8195151 is mechanically and electrically compatible in pitch, position count, and mounting type. However, it features male pins instead of female sockets. Direct substitution requires verification that the mating connector accepts male pins. If the existing system requires female sockets, this part is not suitable without connector redesign.

Q: What is the difference between the Weidmüller 1528110000 and 1943980000?

A: Both are Weidmüller Omnimate BL series 19-position, 5.08mm pitch terminal block plugs with female sockets. The 1943980000 is active (vs. obsolete), supports higher current (20A UL vs. 15A UL), accepts larger wire gauges (12-30 AWG vs. 12-26 AWG), and is RoHS compliant. Electrical and mechanical compatibility is maintained.

Q: Are the TE Connectivity parts (1-796634-9 and 1-796635-9) interchangeable?

A: Yes. Both are Buchanan series 19-position, 5.08mm pitch terminal block plugs with identical electrical ratings and mechanical specifications. The only difference is housing color: 1-796634-9 is green, 1-796635-9 is black. Selection depends on color coding requirements in your application.

Q: What wire gauges are supported by each substitute?

A: Weidmüller 1528110000 supports 12-26 AWG (0.2-2.5mm²). Weidmüller 1943980000 supports 12-30 AWG (0.2-4mm²). TE Connectivity parts support 12-30 AWG (0.05-3mm²). On Shore Technology OSTV8195151 supports 12-22 AWG. Verify your wire gauge falls within the supported range of your selected substitute.

Q: Are all substitutes RoHS compliant?

A: Weidmüller 1943980000 is RoHS compliant. TE Connectivity 1-796634-9 is ROHS3 compliant. TE Connectivity 1-796635-9 is RoHS compliant. On Shore Technology OSTV8195151 is ROHS3 compliant. The original 1528110000 RoHS status is not specified. Verify compliance requirements for your application.

Q: What is the operating temperature range for each part?

A: Weidmüller 1528110000 and 1943980000 operate -50°C to 100°C. TE Connectivity 1-796634-9 and 1-796635-9 operate -40°C to 110°C. On Shore Technology OSTV8195151 operates -40°C to 115°C. Select based on your system's thermal requirements.

Q: Can I mix substitute parts in the same system?

A: All listed substitutes maintain 19-position, 5.08mm pitch, 180° free-hanging configuration and meet minimum UL electrical ratings. Mechanical and electrical interchangeability is supported. However, verify contact type compatibility (female sockets vs. male pins) with your mating connectors before mixing parts.
