Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 5-146281-3

The 5-146281-3 is the direct active equivalent from the original manufacturer TE Connectivity. This part maintains identical electrical and mechanical specifications to the obsolete 5-146293-3, with the exception of termination method (solder-only versus press-fit/solder). The 5-146281-3 carries active product status and full ROHS3 compliance, making it the preferred choice for direct replacement in existing designs. Current inventory availability is 3700 pieces.

Secondary Recommendation: Sullins Connector Solutions PBC03SAAN

The PBC03SAAN provides functional equivalence with the following considerations: it maintains the same 3-position, 0.100" pitch configuration and 3A current rating. The contact length - post dimension (0.120") matches the main part exactly. The primary differences are insulation material (PBT versus LCP), contact material (Phosphor Bronze versus Copper Alloy), and extended operating temperature range (-65°C ~ 125°C). This part is active with 20545 pieces in inventory and carries ROHS3 compliance.

Alternative Selections by Contact Length - Post Requirement:

For applications requiring extended board penetration, Sullins PBC03 series parts offer graduated post lengths:

PBC03SABN: 0.230" post length (4978 pieces available)
PBC03SACN: 0.320" post length (980 pieces available)
PBC03SADN: 0.420" post length (1515 pieces available)
PBC03SAEN: 0.520" post length (1087 pieces available)
PBC03SAFN: 0.620" post length (850 pieces available)
PBC03SAGN: 0.720" post length (904 pieces available)
PBC03SAHN: 0.820" post length (1110 pieces available)

All Sullins alternatives maintain active product status, ROHS3 compliance, and 3A current rating. Selection among these variants depends on specific board thickness and application requirements.

Contact Finish Consideration:

The PEC03SAAN variant from Sullins provides tin-plated mating contacts (100.0µin thickness) instead of gold plating, with identical post length (0.120") to the main part. This option is suitable for cost-sensitive applications where gold plating is not required. Inventory availability is 11715 pieces.

Frequently Asked Questions (FAQ)

Q: Can the obsolete 5-146293-3 be directly replaced with the 5-146281-3?

A: Yes. The 5-146281-3 maintains identical pitch (0.100"), position count (3), contact length - mating (0.230"), contact length - post (0.120"), and current rating (3A). The primary difference is termination method: the 5-146281-3 is solder-only, while the original part supported both press-fit and solder termination. For solder-based applications, direct substitution is valid.

Q: What is the difference between TE Connectivity and Sullins connector options?

A: TE Connectivity 5-146281-3 uses Copper Alloy contacts with Liquid Crystal Polymer (LCP) insulation. Sullins PBC03 series uses Phosphor Bronze contacts with Polybutylene Terephthalate (PBT) insulation. Both meet UL94 V-0 flammability requirements and ROHS3 compliance. Sullins parts offer extended operating temperature range (-65°C ~ 125°C versus -65°C ~ 105°C) and higher inventory availability.

Q: How do I select the correct Sullins PBC03 variant?

A: Selection is determined by required contact length - post dimension, which affects how far the connector pins penetrate the printed circuit board. The PBC03SAAN matches the original 0.120" post length. Longer post lengths (PBC03SABN through PBC03SAHN) accommodate thicker boards or applications requiring deeper penetration. Verify your board thickness and connector mounting depth requirements before selection.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting current environmental and hazardous substance restrictions.

Q: What is the difference between gold-plated and tin-plated mating contacts?

A: Gold-plated contacts (30.0µin or 10.0µin thickness) provide superior corrosion resistance and lower contact resistance. Tin-plated contacts (100.0µin thickness on mating surface) are suitable for general-purpose applications where cost optimization is prioritized. The PEC03SAAN provides tin-plated mating contacts while maintaining all other electrical specifications.

Q: Can I use a substitute part with a longer contact post length in my existing design?

A: Longer post lengths increase board penetration depth. Verify that your printed circuit board thickness and component layout accommodate the extended post length. Consult your board design specifications and mechanical assembly requirements before selecting variants with post lengths exceeding 0.120".

Q: What is the inventory status of these parts?

A: The 5-146281-3 has 3700 pieces in stock. Sullins alternatives range from 850 to 20545 pieces depending on variant. The PBC03SAAN offers the highest inventory availability at 20545 pieces, providing supply chain security for high-volume applications.

Q: Are there any termination method differences I should consider?

A: The original 5-146293-3 supported both press-fit and solder termination. All substitute parts listed support solder termination only. If your application requires press-fit termination capability, consult with the connector manufacturer for alternative options.
