Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 1-146290-7 is determined by strict equivalence across the following critical parameters:

Position and Pitch Compatibility: The substitute part must maintain 17 positions with 0.100" (2.54mm) mating pitch to ensure mechanical and electrical compatibility with existing mating connectors and PCB layouts.

Contact Configuration: Male pin contact type with identical contact dimensions (0.230" mating length, 0.120" post length, 0.440" overall length) ensures proper engagement and signal integrity.

Mounting and Termination: Through-hole mounting type with compatible termination methods (solder capability) allows direct replacement in existing PCB designs without layout modifications.

Electrical and Environmental Ratings: Operating temperature range of -65°C to 105°C, 3A current rating per contact, and UL94 V-0 flammability rating must be maintained to preserve application performance and safety compliance.

Material and Finish Specifications: Copper alloy contacts with tin or tin-lead finish, LCP insulation material, and black insulation color ensure electrical performance and environmental resistance equivalent to the original part.

Regulatory Compliance: RoHS compliance status must be maintained for applications subject to hazardous substance restrictions.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 6-146278-7 serves as the direct substitute for the obsolete 1-146290-7. Both connectors maintain identical mechanical and electrical specifications across all critical parameters including position count, pitch spacing, contact dimensions, operating temperature range, and current rating.

The primary distinction between these parts is product status: the 1-146290-7 is obsolete while the 6-146278-7 maintains active production status. This transition ensures continued availability and supply chain stability for new designs and production requirements.

A secondary difference exists in termination options: the 1-146290-7 offers both press-fit and solder termination, while the 6-146278-7 provides solder termination only. For applications requiring press-fit termination exclusively, this distinction must be evaluated against design requirements.

Contact finish composition differs between the parts: the 1-146290-7 utilizes tin-lead finish while the 6-146278-7 employs tin finish. Both finishes maintain equivalent contact finish thickness (100.0µin / 2.54µm) and provide compatible electrical performance. The tin finish of the substitute part aligns with contemporary RoHS compliance requirements.

Both connectors carry UL94 V-0 flammability rating, EAR99 export classification, and identical HTSUS commodity codes, confirming regulatory and compliance equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 6-146278-7 directly replace the 1-146290-7 in existing designs?

A: Yes. The 6-146278-7 maintains identical mechanical and electrical specifications across all critical parameters including position count (17), pitch spacing (0.100" / 2.54mm), contact dimensions, operating temperature range (-65°C to 105°C), and current rating (3A). Direct substitution is supported for applications utilizing solder termination.

Q: What is the significance of the product status difference?

A: The 1-146290-7 carries obsolete status, indicating discontinuation from active manufacturing. The 6-146278-7 maintains active production status, ensuring reliable supply availability for current and future production requirements. Obsolete parts face increasing scarcity and potential supply interruptions.

Q: Does the termination method difference affect compatibility?

A: The 1-146290-7 offers both press-fit and solder termination options, while the 6-146278-7 provides solder termination only. For applications utilizing solder termination exclusively, this difference does not affect compatibility. Applications requiring press-fit termination must evaluate alternative solutions.

Q: Are the contact finish specifications equivalent?

A: The 1-146290-7 uses tin-lead finish while the 6-146278-7 uses tin finish. Both maintain identical finish thickness (100.0µin / 2.54µm) and provide compatible electrical performance. The tin finish of the substitute aligns with contemporary RoHS compliance standards.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence across position count, mating pitch, contact type and dimensions, mounting type, operating temperature range, current rating, contact material, insulation material, and flammability rating. All these parameters remain identical between the main part and substitute.

Q: Are there any regulatory compliance considerations?

A: Both connectors carry UL94 V-0 flammability rating and EAR99 export classification. The 1-146290-7 is explicitly RoHS compliant. The 6-146278-7 maintains equivalent regulatory standing through identical material composition and specifications.

Q: What is the inventory status for each part?

A: The 1-146290-7 has 817 pieces in stock as new original inventory. The 6-146278-7 has 700 pieces in stock as new original inventory. Both parts maintain current availability through TE Connectivity distribution channels.
