Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1-284512-7 is determined by the following critical parameters:

Core Compatibility Parameters:

• 17 positions with 0.138" (3.50mm) pitch
• 90° right-angle through-hole mounting
• Solder termination
• UL voltage rating of 300 V minimum
• UL current rating of 10 A or greater
• UL94 V-0 flammability rating
• Operating temperature range encompassing -40°C to 110°C

Mechanical Compatibility:

• Male pin configuration
• Shrouded header design (4-side shrouding preferred for direct replacement)

The substitute parts listed below meet these core parameters while offering active product status and enhanced compliance certifications. Variations in housing material, contact material composition, and shrouding configuration (2-side versus 4-side) are noted as secondary differentiators that do not preclude functional substitution when electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Weidmüller 1619380000

The Weidmüller 1619380000 provides the closest functional equivalence to the TE Connectivity 1-284512-7. Both components feature 4-side shrouded male pin headers with identical 17-position, 3.50mm pitch, and 90° right-angle through-hole configuration. The 1619380000 maintains UL300V/10A electrical specifications, UL94 V-0 flammability compliance, and tin contact mating finish. The active product status and RoHS compliance of the 1619380000 support long-term design continuity and regulatory alignment.

Secondary Substitute: Weidmüller 1841780000

The Weidmüller 1841780000 offers identical mechanical and electrical compatibility with the primary substitute, with the distinction of liquid crystal polymer (LCP) glass-filled housing material in place of polybutylene terephthalate (PBT). This alternative maintains all critical electrical parameters, UL94 V-0 rating, and active product status. The LCP housing provides enhanced thermal and dimensional stability characteristics.

Alternative Substitute: Weidmüller 1618990000

The Weidmüller 1618990000 meets core electrical and mechanical requirements with the exception of shrouding configuration, featuring 2-side shrouding instead of 4-side. This component is suitable for applications where shrouding geometry does not impose design constraints. The 1618990000 delivers equivalent electrical performance and active product status.

All three Weidmüller alternatives provide RoHS compliance and REACH unaffected status, addressing regulatory requirements not specified for the obsolete TE Connectivity original part.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1619380000 directly replace the TE Connectivity 1-284512-7 in existing designs?

A: The Weidmüller 1619380000 is mechanically and electrically compatible for direct substitution. Both components feature 17 positions, 3.50mm pitch, 90° right-angle through-hole mounting, and 4-side shrouding. Electrical specifications (300V UL, 10A UL minimum) meet or exceed the original part requirements. Physical dimensions vary slightly in contact tail length (0.126" versus 0.134") and insulation height (0.298" versus 0.287"), which typically do not affect PCB layout compatibility for standard through-hole applications.

Q: What is the difference between the 1619380000 and 1841780000 substitutes?

A: Both parts are mechanically and electrically identical with respect to position count, pitch, orientation, and electrical ratings. The primary difference is housing material composition: the 1619380000 uses polybutylene terephthalate (PBT), while the 1841780000 uses liquid crystal polymer (LCP) with glass filling. The LCP variant provides enhanced thermal stability and dimensional consistency under elevated temperature conditions.

Q: Why does the Weidmüller 1618990000 have 2-side shrouding instead of 4-side?

A: The 1618990000 is a variant within the Weidmüller Omnimate SL series designed for applications where full 4-side shrouding is not required. It maintains identical electrical specifications and position/pitch configuration. Selection between 2-side and 4-side shrouding depends on application-specific EMI shielding, mechanical protection, and connector mating requirements.

Q: Are there temperature range differences between the original and substitute parts?

A: The TE Connectivity 1-284512-7 operates from -40°C to 110°C, while all Weidmüller substitutes operate from -50°C to 100°C. The Weidmüller parts provide lower minimum temperature capability (-50°C versus -40°C) but a reduced maximum temperature rating (100°C versus 110°C). Applications requiring operation above 100°C require evaluation against specific thermal requirements.

Q: Are the Weidmüller substitutes RoHS compliant?

A: All three Weidmüller substitute parts (1618990000, 1619380000, and 1841780000) are RoHS compliant. The original TE Connectivity 1-284512-7 lists RoHS status as "Not applicable," indicating it predates RoHS compliance requirements. The substitutes support modern regulatory compliance frameworks.

Q: What is the significance of the contact tail length difference?

A: The TE Connectivity original part features a contact tail length of 0.134" (3.40mm), while Weidmüller substitutes measure 0.126" (3.20mm). This 0.008" (0.20mm) difference is within standard PCB through-hole tolerance ranges and does not typically affect solder joint formation or mechanical reliability in standard applications. PCB design review is recommended for applications with tight solder fillet or clearance specifications.

Q: Can I use the 1618990000 (2-side shrouded) in place of the 4-side shrouded original?

A: The 1618990000 is electrically and mechanically compatible for substitution. The 2-side shrouding configuration provides reduced EMI shielding and mechanical protection compared to 4-side shrouding. Selection depends on whether the application requires full shrouding for signal integrity, mechanical robustness, or connector mating alignment. PCB layout and connector interface specifications should be reviewed to confirm compatibility.
