Engineering Selection Recommendations
Primary Recommendation: TE Connectivity 5-146258-7
The TE Connectivity 5-146258-7 is the manufacturer-recommended equivalent for the obsolete 146270-7. This part maintains identical mating and row spacing parameters, matching contact dimensions and overall form factor. The transition from kinked pin to standard solder termination does not affect electrical or mechanical compatibility. The 5-146258-7 achieves RoHS compliance, addressing regulatory requirements for new designs while maintaining full functional equivalence. Active product status ensures ongoing availability and supply chain stability.
Secondary Recommendations: Molex C-Grid 70280 Series
The Molex C-Grid 70280 series (part numbers 0010897140, 0010897141, 0010897142, 0702800595, 0702800635, 0702800675) provides cross-manufacturer alternatives with identical mating pitch and row spacing. These parts feature extended contact post lengths (0.107" to 0.175") compared to the original 0.090", accommodating deeper PCB mounting applications. All variants maintain UL94 V-0 flammability rating and ROHS3 compliance. Contact finish options include tin and gold plating at varying thicknesses.
Tertiary Recommendations: Molex C-Grid 70287 Series
The Molex C-Grid 70287 series (part numbers 0702871005, 0702871103, 0702871201) offers kinked pin solder termination matching the original 146270-7 termination style. These parts feature intermediate contact post length (0.125") and maintain all core electrical and mechanical specifications. ROHS3 compliance and active product status support modern design requirements.
Compliance Considerations
The original 146270-7 carries RoHS non-compliant status. All recommended substitutes achieve either RoHS or ROHS3 compliance, supporting regulatory requirements for new product designs and procurement cycles. Contact finish transitions from tin-lead to tin or gold plating reflect current manufacturing standards and environmental regulations.
Frequently Asked Questions (FAQ)
Q: Can the TE Connectivity 5-146258-7 directly replace the 146270-7 in existing designs?
A: The 5-146258-7 maintains identical mating pitch (0.100"), row spacing (0.100"), number of positions (14), and contact dimensions. The termination change from kinked pin to standard solder does not affect electrical or mechanical compatibility. PCB footprints designed for the 146270-7 accommodate the 5-146258-7 without modification.
Q: What is the primary difference between TE Connectivity and Molex alternatives?
A: The TE Connectivity 5-146258-7 is the direct manufacturer equivalent with identical contact geometry. Molex C-Grid 70280 and 70287 series parts maintain core mating parameters but feature extended contact post lengths (0.107" to 0.175" versus 0.090"), enabling deeper PCB mounting. Contact finish options vary across the Molex lineup, with tin and gold plating available at different thicknesses.
Q: Are Molex parts compatible with PCB footprints designed for the 146270-7?
A: Molex parts are mechanically compatible at the mating interface due to identical pitch and row spacing. However, the extended contact post lengths require verification of PCB hole depth and solder pad layout. Designs with shallow PCB mounting may require footprint adjustment to accommodate the longer posts.
Q: What is the significance of contact finish differences (tin versus gold)?
A: Contact finish affects corrosion resistance and mating force characteristics. Tin-plated contacts (0010897141, 0702800595, 0702871005) provide standard performance for general applications. Gold-plated contacts (0010897140, 0010897142, 0702800635, 0702871103, 0702871201) offer enhanced corrosion resistance for high-reliability or harsh environment applications. Finish thickness varies across part numbers, with thicker plating providing extended service life.
Q: Does the kinked pin termination style affect substitution compatibility?
A: Kinked pin termination (146270-7, 0702871005, 0702871103, 0702871201) and standard solder termination (5-146258-7, 0010897140, 0010897141, 0010897142, 0702800595) are both compatible with standard PCB soldering processes. Kinked pins provide additional mechanical retention during assembly. Standard solder termination simplifies manufacturing. Selection depends on assembly process requirements and mechanical retention preferences.
Q: What is the impact of RoHS compliance on part selection?
A: The original 146270-7 is RoHS non-compliant due to tin-lead contact finish. All recommended substitutes achieve RoHS or ROHS3 compliance through transition to tin or gold plating. For new product designs subject to RoHS regulations, the 5-146258-7, Molex C-Grid 70280, and C-Grid 70287 series parts satisfy compliance requirements.
Q: Are there inventory considerations when selecting between alternatives?
A: The TE Connectivity 5-146258-7 maintains the largest active inventory (12,848 units) among direct equivalents. Molex C-Grid 70280 and 70287 series parts show varying inventory levels (671 to 6,964 units), with 0010897140 offering the highest Molex availability (6,964 units). Procurement strategy should account for supply chain stability and lead time requirements.
Q: Can the 146270-7 be used in new designs, or must substitutes be selected?
A: The 146270-7 is classified as obsolete and carries RoHS non-compliant status. New product designs should specify active alternatives such as the TE Connectivity 5-146258-7 or Molex C-Grid series to ensure long-term supply availability and regulatory compliance. Existing legacy systems may continue using the 146270-7 if inventory permits and regulatory exemptions apply.
