• Connector type: Header, Breakaway configuration
• Mounting method: Through Hole
• Shrouding: Unshrouded

Electrical Compatibility Parameters:

• Contact type: Male Pin
• Current rating: 3A
• Operating temperature range: -65°C ~ 105°C
• Contact material: Copper Alloy
• Insulation material: Liquid Crystal Polymer (LCP)

Physical Dimensions:

• Contact length - mating: 0.230" (5.84mm)
• Contact length - post: 0.120" (3.05mm)
• Overall contact length: 0.440" (11.18mm)
• Insulation height: 0.090" (2.29mm)

The substitute part 5-146256-5 maintains full equivalence across all mechanical and electrical parameters while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 5-146256-5 connector serves as the direct active equivalent for the obsolete 146256-5 model. Both components are manufactured by TE Connectivity within the AMPMODU Mod II series and maintain identical mechanical and electrical specifications across all critical parameters.

Compliance Status: The substitute part 5-146256-5 carries ROHS3 compliance certification, representing an enhancement over the RoHS Compliant status of the original part. Both components maintain UL94 V-0 flammability rating and unlimited moisture sensitivity level (MSL 1).

Contact Finish Variation: The substitute part features Tin post contact finish compared to the Tin-Lead finish of the original part. This represents a lead-free evolution consistent with modern manufacturing standards while maintaining equivalent electrical and mechanical performance at the specified 3A current rating.

Product Availability: The original 146256-5 is classified as obsolete with limited inventory. The 5-146256-5 maintains active product status with higher inventory availability (2200 pieces in stock versus 1138 pieces for the original), ensuring supply chain continuity for new designs and production requirements.

Interchangeability: Full pin-to-pin and footprint compatibility is maintained between the two parts. No circuit board redesign or connector housing modifications are required for substitution.

Frequently Asked Questions (FAQ)

Q: Are the 146256-5 and 5-146256-5 connectors pin-compatible?

A: Yes. Both connectors maintain identical pin configurations with 10 positions arranged in 2 rows at 0.100" (2.54mm) pitch spacing. Male pin contact type, contact length, and overall dimensions are identical across both parts.

Q: What is the difference between Tin-Lead and Tin post contact finishes?

A: The original 146256-5 uses Tin-Lead post finish, while the substitute 5-146256-5 uses Tin post finish. Both finishes provide equivalent electrical conductivity and solder joint reliability at the 3A current rating. The Tin finish represents a lead-free alternative consistent with current manufacturing practices.

Q: Can I use the 5-146256-5 as a direct replacement in existing designs?

A: Yes. The 5-146256-5 maintains full mechanical and electrical equivalence to the 146256-5. No circuit board layout modifications, connector housing changes, or mating connector adjustments are required. The parts are directly interchangeable.

Q: Why is the original 146256-5 marked as obsolete?

A: The 146256-5 has been superseded by the 5-146256-5 within the TE Connectivity product line. The substitute part offers active product status, improved compliance certifications (ROHS3), and better supply chain availability while maintaining identical functional specifications.

Q: What is the difference in packaging between the two parts?

A: The original 146256-5 packaging is not specified in the product data. The substitute 5-146256-5 is supplied in Bulk packaging, which is the standard distribution format for this connector type.

Q: Are both connectors rated for the same operating temperature range?

A: Yes. Both the 146256-5 and 5-146256-5 operate across the identical temperature range of -65°C to 105°C, maintaining full electrical and mechanical performance throughout this range.

Q: What is the current rating for these connectors?

A: Both connectors are rated for 3A continuous current per contact. This rating applies to the male pin contacts and is consistent across all mating and post contact configurations.

Q: Do both parts meet the same flammability standards?

A: Yes. Both the 146256-5 and 5-146256-5 meet UL94 V-0 material flammability rating, indicating compliance with the highest flammability classification standards.

Q: Is the 5-146256-5 RoHS compliant?

A: Yes. The 5-146256-5 carries ROHS3 compliance certification. The original 146256-5 is RoHS Compliant. Both parts meet lead-free and restricted substance requirements applicable to their respective certification levels.
