Key Parameters

Substitute Part Grouping Explanation

The TE Connectivity AMP Connectors part number 1-282841-0 qualifies as a functional substitute for the Weidmüller 995138 based on the following critical parameters:

• Positions and Pitch: Both parts feature 10 positions per level with identical 0.200" (5.08mm) pitch spacing, ensuring PCB footprint compatibility
• Mating Orientation and Mounting: Both are horizontal with board configuration using through-hole mounting
• Voltage Rating: Both rated at 300 V, meeting identical electrical requirements
• Screw Thread: Both use M3 screw threads for wire termination
• Housing Material: Both utilize Polyamide (PA66), Nylon 6/6 construction
• Interlocking Feature: Both incorporate side interlocking design

The substitute part demonstrates enhanced electrical performance with higher current rating (17.5 A vs. 15 A) and expanded wire gauge compatibility (12-30 AWG vs. 12-26 AWG), making it suitable for equivalent or upgraded applications.

Parameter Comparison

Engineering Selection Recommendations

For RoHS-Compliant Applications: The Weidmüller 995138 maintains RoHS compliance and REACH unaffected status. If regulatory compliance is mandatory, the original part or equivalent RoHS-compliant alternatives should be prioritized despite obsolete status.

For Active Production and Long-Term Availability: The TE Connectivity 1-282841-0 is actively manufactured and maintains higher inventory levels (1698 pcs vs. 1101 pcs), providing superior supply chain continuity. This part is suitable for new designs and applications where RoHS non-compliance does not conflict with regulatory requirements.

For Electrical Performance Upgrades: The substitute part offers higher current capacity (17.5 A vs. 15 A) and extended wire gauge range (12-30 AWG vs. 12-26 AWG), supporting applications requiring enhanced electrical performance within the same physical footprint.

Compliance Considerations: Applications subject to RoHS or REACH restrictions must account for the substitute part's non-compliant status. Designs operating in unrestricted regulatory environments may adopt the substitute without compliance constraints.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-282841-0 directly replace the Weidmüller 995138 on existing PCBs?

A: Yes, both parts share identical pitch (5.08mm), position count (10), mounting type (through hole), and screw thread (M3), ensuring direct PCB footprint compatibility without layout modifications.

Q: What are the key differences in wire termination between these parts?

A: The Weidmüller 995138 uses screw-clamping yoke with tension sleeve termination, while the TE Connectivity 1-282841-0 employs rising cage clamp termination. Both are screw-based systems with M3 threads, though torque specifications differ (0.5-0.6 Nm vs. 0.79 Nm).

Q: Is the higher current rating of the substitute part a concern for existing applications?

A: No. The substitute part's 17.5 A rating exceeds the original 15 A specification, making it suitable for equivalent or higher-current applications. Existing designs operating at or below 15 A remain fully compatible.

Q: What packaging format is the substitute part supplied in?

A: The TE Connectivity 1-282841-0 is supplied in bulk packaging, compared to the original part's unspecified packaging. Confirm packaging requirements with procurement specifications.

Q: Are there operating temperature differences between these parts?

A: The Weidmüller 995138 specifies -20°C to 100°C operating range. The TE Connectivity substitute does not provide explicit operating temperature data in available specifications. Verify temperature requirements for critical thermal applications.

Q: How do the compliance statuses affect part selection?

A: The Weidmüller 995138 is RoHS compliant and REACH unaffected. The TE Connectivity 1-282841-0 is RoHS non-compliant and REACH affected. Applications subject to EU or equivalent regulatory frameworks must account for these differences during design phase.
