Engineering Selection Recommendations

3M 2328-5121-TB and 3M 2328-5121-TG

Both 3M substitute parts are classified as active products, providing superior long-term availability compared to the obsolete TE Connectivity 1-104353-4. These connectors maintain electrical and mechanical compatibility with the original part across all critical parameters.

The 3M 2328-5121-TB and 2328-5121-TG differ primarily in contact finish thickness on the mating surface (30.0µin versus 10.0µin). Both maintain the same gold plating specification and copper alloy contact material. The 3M parts feature glass-filled thermoplastic insulation, which provides enhanced mechanical and thermal stability compared to standard thermoplastic.

Both substitute parts operate at the maximum temperature of 105°C, meeting the thermal requirements of the original specification. The operating temperature minimum of -55°C is acceptable for applications where the original -65°C minimum is not required.

The 3M parts are specified for solder termination only, whereas the original TE Connectivity part supports both press-fit and solder termination. Applications requiring press-fit termination must evaluate the 3M parts' solder-only configuration against design requirements.

All three connectors maintain UL94 V-0 flammability rating, identical current rating of 3A, and equivalent moisture sensitivity classification. Compliance status remains consistent across RoHS non-compliance, REACH affected designation, and ECCN/HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the 3M 2328-5121-TB or 2328-5121-TG directly replace the TE Connectivity 1-104353-4 in existing designs?

A: Yes, both 3M parts are direct substitutes for the TE Connectivity 1-104353-4. All critical electrical and mechanical parameters match, including position count, pitch spacing, contact type, mounting configuration, and current/voltage ratings. The connectors are mechanically and electrically interchangeable.

Q: What is the difference between the 3M 2328-5121-TB and 2328-5121-TG?

A: The primary difference is the contact finish thickness on the mating surface. The 2328-5121-TB features 30.0µin (0.76µm) gold plating, matching the original TE Connectivity specification. The 2328-5121-TG features 10.0µin (0.25µm) gold plating. Both maintain equivalent electrical performance and contact reliability. Selection depends on application-specific contact durability requirements.

Q: Why does the original TE Connectivity part support press-fit termination while the 3M substitutes support only solder termination?

A: The TE Connectivity 1-104353-4 was designed with dual termination capability (press-fit and solder). The 3M 2300 series connectors are optimized for solder termination only. Applications requiring press-fit termination must confirm that solder-only termination is acceptable for the circuit board design and assembly process.

Q: Are there any temperature range limitations when substituting the 3M parts?

A: The 3M substitutes operate from -55°C to 105°C, compared to the original -65°C to 105°C range. The maximum temperature of 105°C is identical. If the application requires operation below -55°C, the original TE Connectivity part or alternative sources must be evaluated.

Q: Do the substitute parts meet the same compliance and regulatory requirements?

A: Yes. Both 3M substitute parts maintain identical compliance status: UL94 V-0 flammability rating, RoHS non-compliant, REACH affected, and equivalent ECCN/HTSUS classifications. Regulatory and safety requirements are equivalent across all three connectors.

Q: What is the significance of the glass-filled thermoplastic insulation in the 3M parts?

A: The glass-filled thermoplastic insulation in the 3M 2300 series provides enhanced mechanical strength and thermal stability compared to standard thermoplastic. This material composition improves dimensional stability and reduces creep under sustained load or elevated temperature conditions, contributing to improved long-term reliability.

Q: Are the insulation height differences between the original and substitute parts significant?

A: The insulation height variation is 0.004" (0.10mm), with the 3M parts measuring 0.242" (6.14mm) compared to the original 0.238" (6.05mm). This minor difference is within standard manufacturing tolerances and does not affect mechanical or electrical compatibility in standard board-to-board or cable applications.

Q: What is the contact length post difference, and does it affect compatibility?

A: The original TE Connectivity part features 0.120" (3.05mm) post length, while the 3M substitutes feature 0.110" (2.79mm) post length. Both are designed for solder termination (the 3M parts) or press-fit/solder termination (the original). The post length difference is within acceptable tolerances for standard PCB through-hole mounting and does not affect electrical performance or mechanical fit.

Q: Can I use the 3M parts in applications where the original 30VAC voltage rating is critical?

A: The 3M substitute parts do not specify a voltage rating in the provided data. Applications with specific voltage requirements should confirm that the 3M parts' electrical characteristics meet the 30VAC specification through direct manufacturer consultation or electrical testing if voltage rating is a critical design parameter.
