Key Parameters

Substitute Part Grouping Explanation

Substitution of the 146285-3 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Header, Breakaway)
• Contact type (Male Pin)
• Pitch specification (0.100" / 2.54mm)
• Number of positions (3)
• Number of rows (1)
• Mounting method (Through Hole)
• Termination method (Solder)

Electrical & Environmental Compatibility:

• Current rating (3A minimum)
• Operating temperature range (-65°C ~ 105°C minimum)
• Material flammability rating (UL94 V-0)
• Moisture sensitivity level (MSL 1)

Regulatory Compliance:

• RoHS compliance status
• REACH compliance status

The substitute part 5-146285-3 maintains identical mechanical and electrical specifications while differing in product status (Active vs. Obsolete) and packaging configuration (Bulk vs. standard packaging). Contact finish on the post differs between tin-lead (original) and tin (substitute), representing a minor material variation within acceptable parameters for this connector class.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 5-146285-3

The 5-146285-3 is the direct substitute for the obsolete 146285-3. This part maintains full mechanical and electrical compatibility across all critical parameters. The substitute is currently in active production status with significantly higher inventory availability (64,795 pieces vs. 1,142 pieces).

Compliance Advantages:

The 5-146285-3 carries ROHS3 compliance status, representing current regulatory alignment. The original 146285-3 is REACH Affected, while the substitute is REACH Unaffected, indicating improved regulatory positioning for new designs and long-term supply chain stability.

Material Consideration:

The contact finish on the post differs between the original (Tin-Lead) and substitute (Tin). Both finishes are applied at 100.0µin (2.54µm) thickness. This variation reflects industry-wide transition toward lead-free soldering practices and does not impact electrical performance or mechanical compatibility in standard through-hole solder applications.

Availability & Continuity:

Selection of the 5-146285-3 ensures access to active production inventory and ongoing manufacturer support. The obsolete status of the original part creates long-term supply risk for replacement and repair applications.

Frequently Asked Questions (FAQ)

Q: Can the 5-146285-3 be used as a direct replacement for the 146285-3 in existing designs?

A: Yes. The 5-146285-3 maintains identical mechanical dimensions, electrical ratings, and contact specifications. Through-hole mounting and solder termination are identical. The connector will function identically in existing PCB layouts and mating configurations.

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

A: Both finishes provide equivalent electrical conductivity and corrosion resistance for standard through-hole solder applications. The tin finish on the 5-146285-3 reflects compliance with lead-free soldering standards. The 100.0µin (2.54µm) thickness specification is maintained on both parts, ensuring consistent contact resistance and durability.

Q: Why does the REACH status differ between the two parts?

A: The original 146285-3 is classified as REACH Affected due to its obsolete status and historical manufacturing records. The 5-146285-3, as an active production part, is classified as REACH Unaffected. This reflects current regulatory documentation and supply chain compliance. Both parts are suitable for use; the substitute offers improved regulatory clarity for new applications.

Q: Are there any packaging differences between 146285-3 and 5-146285-3?

A: The original 146285-3 is supplied in standard packaging, while the 5-146285-3 is supplied in bulk packaging. Both configurations contain identical connector components. Bulk packaging is standard for active production parts and does not affect connector performance or compatibility.

Q: What is the operating temperature range for both connectors?

A: Both the 146285-3 and 5-146285-3 operate across the identical temperature range of -65°C to 105°C. This specification is maintained across all environmental and thermal cycling applications within this range.

Q: Is the 3-position, 2.54mm pitch configuration the only available option in this series?

A: The provided data covers only the 3-position configuration. The AMPMODU Mod II series supports multiple position counts and pitch specifications. Selection of alternative configurations requires separate evaluation based on specific application requirements.

Q: What is the current rating for these connectors?

A: Both connectors are rated for 3A continuous current per contact. This rating applies to standard operating conditions within the specified temperature range and assumes proper solder joint formation and PCB trace sizing.

Q: Are these connectors suitable for high-reliability applications?

A: Both connectors meet UL94 V-0 flammability requirements and carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating suitability for standard industrial and commercial applications. Specific high-reliability requirements should be evaluated against application-specific standards and environmental conditions.
