Key Parameters

Substitute Part Grouping Explanation

Substitution of the 146281-2 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Connector type (Header, Breakaway)
• Contact type (Male Pin)
• Number of positions (2)
• Pitch spacing (0.100" / 2.54mm)
• Current rating (3A)
• Operating temperature range (-65°C ~ 105°C)

Mechanical Compatibility:

• Mounting type (Through Hole)
• Termination method (Solder)
• Insulation material (Liquid Crystal Polymer)
• Contact finish specifications (Gold mating surface)

Regulatory Compliance:

• RoHS Compliant status
• UL94 V-0 flammability rating
• ECCN classification (EAR99)

The substitute part 5-146281-2 maintains full equivalence across all critical parameters while offering active product status and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5-146281-2 is a direct functional equivalent to the obsolete 146281-2. Both parts maintain identical electrical and mechanical specifications across all critical parameters.

Key Advantages of 5-146281-2:

The substitute part carries active product status, ensuring ongoing availability and supply chain support. Both parts are RoHS Compliant and carry UL94 V-0 flammability certification, meeting current regulatory requirements.

The primary difference is the contact finish on the post: the original part uses Tin-Lead, while the substitute uses Tin. This change reflects modern RoHS compliance standards and does not affect electrical or mechanical performance. Tin finish provides equivalent solderability and contact reliability for through-hole applications.

Both parts are classified as MSL 1 (Unlimited moisture sensitivity), indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can 5-146281-2 be used as a direct replacement for 146281-2 in existing designs?

A: Yes. The 5-146281-2 maintains identical electrical and mechanical specifications. All critical parameters including connector type, position count, pitch spacing, current rating, operating temperature range, and mounting method are equivalent. The parts are mechanically and electrically interchangeable.

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

A: The original 146281-2 uses Tin-Lead finish, while the substitute 5-146281-2 uses Tin finish. Both finishes provide equivalent solderability and contact reliability. The change to Tin reflects RoHS compliance requirements. Both finishes maintain the same thickness specification of 100.0µin (2.54µm).

Q: Are there any packaging differences between these parts?

A: The original 146281-2 packaging is not specified in the available data. The substitute 5-146281-2 is supplied in Bulk packaging. Confirm packaging requirements for your specific application needs.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts are RoHS Compliant, carry UL94 V-0 flammability rating, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. Both parts have MSL 1 (Unlimited) moisture sensitivity level.

Q: Why is the original 146281-2 marked as obsolete?

A: The 146281-2 is an obsolete product from the AMPMODU Mod II series. The substitute 5-146281-2 is the active equivalent part that maintains full compatibility while providing current supply availability.

Q: What is the current availability of these parts?

A: The original 146281-2 has 1072 pieces in stock as new original inventory. The substitute 5-146281-2 has 2400 pieces in stock and carries active product status, ensuring continued availability.

Q: Are the contact dimensions identical between both parts?

A: Yes. Both parts share identical contact specifications: mating contact length of 0.230" (5.84mm), post contact length of 0.120" (3.05mm), and overall contact length of 0.440" (11.18mm). Insulation height is 0.090" (2.29mm) for both parts.

Q: Can these connectors be used in high-temperature applications?

A: Yes. Both parts are rated for operating temperatures from -65°C to 105°C, supporting a wide range of industrial and commercial applications within this temperature envelope.
