Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-103328-7 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 34 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing
• Connector Type: Header with breakaway capability
• Contact Specifications: Male pins, square contact shape, copper alloy material
• Electrical Performance: 3A current rating, -65°C to 105°C operating temperature range
• Mechanical Interface: Through-hole solder termination, push-pull fastening
• Compliance: UL94 V-0 flammability rating, MSL 1 (Unlimited)

The substitute part 6-146254-7 maintains full electrical and mechanical compatibility across all specified parameters while offering active product status and improved compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 6-146254-7 serves as the direct active equivalent to the obsolete 1-103328-7. Both connectors maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, contact configuration, current rating, and operating temperature range.

The primary distinction between these parts is product lifecycle status and compliance posture. The 1-103328-7 is classified as obsolete and carries RoHS non-compliant status with tin-lead contact finish. The 6-146254-7 is an active product with RoHS compliance and tin contact finish, reflecting current manufacturing standards and regulatory requirements.

Material composition differs in the insulation substrate: the main part uses thermoplastic while the substitute employs Liquid Crystal Polymer (LCP). Both materials satisfy the UL94 V-0 flammability requirement and maintain equivalent electrical performance within the specified operating temperature range.

For new designs and ongoing production requiring this connector configuration, the 6-146254-7 is the appropriate selection. For legacy system maintenance where original specifications must be preserved, the 1-103328-7 remains functionally equivalent where available inventory permits.

Frequently Asked Questions (FAQ)

Q: Are the 1-103328-7 and 6-146254-7 mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.100"), row spacing (0.100"), contact length specifications, and overall dimensions. They mount identically in through-hole applications with solder termination.

Q: What is the significance of the contact finish difference (Tin-Lead vs. Tin)?

A: The contact finish difference reflects regulatory evolution. The 1-103328-7 uses tin-lead finish (pre-RoHS standard), while the 6-146254-7 uses tin finish (RoHS compliant). Both finishes provide equivalent electrical conductivity and contact reliability within the specified operating parameters.

Q: Does the insulation material change (Thermoplastic vs. LCP) affect electrical performance?

A: No. Both thermoplastic and Liquid Crystal Polymer insulation materials meet the UL94 V-0 flammability rating and maintain equivalent dielectric properties across the -65°C to 105°C operating temperature range. The material change reflects manufacturing evolution and improved dimensional stability in the active product.

Q: Can the 6-146254-7 be used as a direct replacement in existing assemblies designed for the 1-103328-7?

A: Yes. The 6-146254-7 maintains full compatibility with existing PCB layouts, mating connectors, and electrical specifications. No design modifications are required.

Q: What is the current availability status of each part?

A: The 1-103328-7 is obsolete with 704 pieces in current inventory. The 6-146254-7 is an active product with 847 pieces in current inventory.

Q: Are there any environmental or compliance considerations when selecting between these parts?

A: The 6-146254-7 offers RoHS compliance, making it the preferred choice for applications subject to RoHS regulations or customer requirements. The 1-103328-7 remains suitable for legacy systems or applications without RoHS mandates.
