Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 7-146309-0

The 7-146309-0 is the direct equivalent from the same manufacturer and series (AMPMODU Mod II). This part maintains identical electrical and mechanical specifications to the 7-146311-0 with the exception of termination type (solder only versus press-fit and solder). The 7-146309-0 carries active product status, ensuring ongoing availability and manufacturing support. This part is recommended for direct replacement in new designs and production continuity.

Secondary Recommendations: 3M 929745 Series

The 3M 929745-01-20-I and 929745-01-20-EU parts provide RoHS-compliant alternatives with identical contact post length (0.110"). These parts feature copper alloy contacts with gold finish and operate across -40°C to 105°C. The 929745-02-20-EU variant offers extended contact post length (0.405") for applications requiring deeper board penetration. All three variants maintain active product status and RoHS compliance.

Tertiary Recommendations: Amphenol ICC (FCI) BERGSTIK® II Series

The Amphenol ICC parts (68022-140H, 68022-240HLF, 68459-140, 78276-140H, 79258-140) provide mechanical and electrical compatibility with variations in contact post length and insulation height. These parts feature phosphor bronze contacts with gold finish and UL94 V-0 flammability rating. The 68022-140H and 68022-240HLF variants are RoHS compliant. Contact post length variations (0.110" to 0.150") accommodate different PCB thicknesses and mounting depths.

Alternative Consideration: 3M 2340-5221-TG

The 2340-5221-TG from the 3M 2300 series provides mechanical compatibility with identical contact dimensions and pitch. This part carries UL94 V-0 flammability rating and 3A current rating. However, this part is RoHS non-compliant and should be selected only when RoHS compliance is not a design requirement.

Compliance Considerations:

For applications requiring RoHS compliance, select from: 7-146309-0, 68022-140H, 68022-240HLF, 929745-01-20-EU, 929745-01-20-I, or 929745-02-20-EU.

For applications with extended temperature range requirements (-65°C minimum), the 7-146311-0 and 7-146309-0 provide the widest operating range. The 3M 929745 series operates to -40°C minimum.

For applications requiring higher current capacity, the Amphenol ICC BERGSTIK® II series (68022-140H, 68022-240HLF) provides 5A rating versus 3A for the main part.

Frequently Asked Questions (FAQ)

Q: Can the 7-146309-0 directly replace the 7-146311-0?

A: Yes. The 7-146309-0 is mechanically and electrically compatible. The primary difference is termination type: the 7-146309-0 features solder termination only, while the 7-146311-0 supports both press-fit and solder. For applications using solder termination exclusively, the 7-146309-0 is a direct replacement. The 7-146309-0 carries active product status, making it the preferred choice for new designs.

Q: What is the significance of contact post length variations?

A: Contact post length determines how deeply the connector penetrates the PCB. The main part specifies 0.110" (2.79mm). Substitute parts offer variations: 0.120" (3.05mm), 0.150" (3.81mm), and 0.405" (10.29mm). Longer posts accommodate thicker PCBs or provide additional mechanical support. Shorter posts suit thin PCBs. Selection depends on PCB thickness and mounting requirements. All listed variants maintain mating contact length at 0.318" (8.08mm), ensuring proper mating interface.

Q: Are the Amphenol ICC BERGSTIK® II parts compatible with TE Connectivity AMPMODU headers?

A: Yes. The Amphenol ICC parts maintain identical pitch (0.100"), contact count (40), row configuration (2 rows), contact length (0.318" mating), and contact shape (square). These parts are mechanically and electrically interchangeable at the mating interface. The primary differences are contact material (phosphor bronze versus copper alloy) and insulation material composition, which do not affect functional compatibility.

Q: What is the difference between the 929745-01-20-I and 929745-01-20-EU variants?

A: Both parts are electrically and mechanically identical with identical contact post length (0.110"). The designation difference reflects regional compliance variations. The 929745-01-20-I features polybutylene terephthalate (PBT) insulation material with glass fill, while the 929745-01-20-EU uses polycyclohexylenedimethylene terephthalate (PCT) insulation. Both materials provide UL94 V-0 flammability rating and RoHS compliance. Selection depends on regional sourcing and material specification requirements.

Q: Why do some substitute parts show lower current ratings?

A: The 3M 929745 series specifies 2.5A current rating versus 3A for the main part. This reflects manufacturer testing and certification standards. For applications requiring 3A or higher current capacity, select parts with equal or higher ratings: 7-146309-0 (3A), 2340-5221-TG (3A), 68022-140H (5A), or 68022-240HLF (5A).

Q: Are all substitute parts RoHS compliant?

A: No. RoHS compliance varies by part. RoHS-compliant options include: 7-146309-0, 68022-140H, 68022-240HLF, 929745-01-20-EU, 929745-01-20-I, and 929745-02-20-EU. RoHS non-compliant parts include: 2340-5221-TG, 68459-140, 78276-140H, and 79258-140. Verify RoHS compliance requirements for your application before part selection.

Q: What packaging options are available?

A: Packaging varies by part number. TE Connectivity 7-146309-0 packaging is not specified. 3M 2340-5221-TG is supplied in tape and reel (TG) format. Amphenol ICC parts are supplied in bulk or bag packaging. 3M 929745 series parts are supplied in bulk packaging. Confirm packaging requirements with procurement specifications before ordering.

Q: Can the 929745-02-20-EU with 0.405" contact post length be used in place of standard 0.110" post length parts?

A: The 929745-02-20-EU is mechanically compatible but features significantly extended contact post length (0.405" versus 0.110"). This variant is suitable only for applications requiring deep board penetration or specific mounting configurations. Standard PCB applications should use parts with standard post length (0.110"). Verify PCB thickness and mounting depth compatibility before selecting extended post length variants.

Q: What is the operating temperature range for each substitute part?

A: Operating temperature ranges vary. The main part 7-146311-0 operates -65°C to 105°C (widest range). The 7-146309-0 does not specify operating temperature. The 3M 2340-5221-TG operates -55°C to 105°C. The 3M 929745 series operates -40°C to 105°C. Amphenol ICC BERGSTIK® II parts do not specify operating temperature. For applications requiring extended low-temperature operation below -40°C, the 7-146309-0 or 2340-5221-TG are preferred options.
