Key Parameters

Substitute Part Grouping Explanation

Substitution of the 4-146277-0 is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Connector type classification (Header, Breakaway)
• Contact type (Male Pin)
• Number of positions (40)
• Pitch specification (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Current rating (3A)
• Operating temperature range capability
• Material flammability rating (UL94 V-0)
• Contact finish type (Gold mating surface)

Substitute Classification:

The TE Connectivity 9-146277-0 qualifies as a direct equivalent substitute. This part maintains identical specifications across all critical parameters while offering active product status and improved compliance posture.

The 3M 2340-6211-TG qualifies as a similar substitute. While maintaining equivalence in core functional parameters (40 positions, 2.54mm pitch, through-hole mounting, 3A rating, UL94 V-0), this part introduces minor variations in insulation material composition and contact finish thickness specifications that remain within acceptable substitution boundaries for standard board-to-board and cable connection applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Substitute: TE Connectivity 9-146277-0

The 9-146277-0 is the recommended substitute for the obsolete 4-146277-0. This part maintains complete electrical and mechanical equivalence across all specified parameters. The primary advantage of this substitution is the active product status of the 9-146277-0, ensuring continued availability and supply chain stability. Additionally, the 9-146277-0 achieves ROHS3 compliance, providing enhanced regulatory alignment for new designs and procurement cycles. The transition from Tin-Lead to Tin contact finish on the post does not impact functional performance within the specified application parameters.

Similar Substitute: 3M 2340-6211-TG

The 2340-6211-TG serves as a viable alternative when supply constraints or design flexibility permit. This part maintains functional equivalence in core connector specifications: 40 positions, 2.54mm pitch, through-hole solder termination, 3A current rating, and UL94 V-0 flammability compliance. The 2340-6211-TG utilizes thermoplastic glass-filled insulation material in place of liquid crystal polymer, with a slightly increased insulation height (0.100" versus 0.090"). The contact post length variation (0.120" versus 0.125") and reduced mating surface gold finish thickness (10.0µin versus 30.0µin) represent minor dimensional and material differences. The operating temperature range extends to -55°C minimum, which is acceptable for applications not requiring the full -65°C lower limit. This part is active and available in high inventory quantities.

Compliance Considerations

Selection between the direct equivalent and similar substitute should account for regulatory requirements. The 9-146277-0 provides ROHS3 compliance for applications subject to RoHS directives. The 2340-6211-TG remains RoHS non-compliant, consistent with the original 4-146277-0 specification.

Frequently Asked Questions (FAQ)

Q: Can the 9-146277-0 be used as a direct replacement for the 4-146277-0 without design modifications?

A: Yes. The 9-146277-0 maintains identical specifications across all critical electrical and mechanical parameters. No design modifications are required. The primary differences are product status (active versus obsolete) and regulatory compliance (ROHS3 compliant versus non-compliant).

Q: What are the key differences between the 9-146277-0 and the 2340-6211-TG?

A: Both parts maintain functional equivalence in connector type, position count, pitch, mounting method, and current rating. The 9-146277-0 retains the AMPMODU Mod II series platform with liquid crystal polymer insulation and maintains the original -65°C lower operating temperature limit. The 2340-6211-TG uses the 3M 2300 series platform with thermoplastic glass-filled insulation and operates to -55°C minimum. The 2340-6211-TG features slightly increased insulation height (0.100" versus 0.090") and reduced mating surface gold finish thickness (10.0µin versus 30.0µin).

Q: Are there any compatibility concerns when substituting the 2340-6211-TG for the 4-146277-0?

A: The 2340-6211-TG is mechanically and electrically compatible for standard board-to-board and cable connection applications. The increased insulation height and minor contact post length variation do not impact functional performance within the specified application parameters. Applications requiring the full -65°C to 105°C operating temperature range should use the 9-146277-0 or 4-146277-0, as the 2340-6211-TG minimum operating temperature is -55°C.

Q: What is the significance of the contact finish differences between these parts?

A: All three parts feature gold mating surface finish for reliable electrical contact. The 4-146277-0 and 9-146277-0 specify 30.0µin (0.76µm) gold thickness, while the 2340-6211-TG specifies 10.0µin (0.25µm). Both thicknesses provide adequate corrosion resistance and contact reliability for the specified 3A current rating and standard environmental conditions. The post finish varies between Tin-Lead (4-146277-0 and 2340-6211-TG) and Tin (9-146277-0), reflecting different manufacturing processes without impact on solder joint performance.

Q: Which substitute part should be selected for new designs?

A: The 9-146277-0 is the preferred selection for new designs. This part provides active product status, ROHS3 compliance, and complete electrical and mechanical equivalence to the original specification. The 2340-6211-TG is suitable when design flexibility permits and supply considerations favor the 3M platform.

Q: Are moisture sensitivity considerations relevant to these connector parts?

A: All three parts carry Moisture Sensitivity Level (MSL) 1 classification, indicating unlimited shelf life without moisture control requirements. Standard handling and storage practices are sufficient for these components.

Q: What packaging options are available for these substitute parts?

A: The 9-146277-0 is available in bulk packaging. The 2340-6211-TG is also available in bulk packaging. Both parts maintain the same functional specifications regardless of packaging configuration.
