Substitute Part Grouping Explanation

Substitution for the 75160-156-04LF is determined by the following critical parameters:

Pitch - Mating: 0.100" (2.54mm) — all substitutes must match this spacing
Number of Positions: 4 positions required
Connector Type: Header configuration
Contact Type: Male Pin
Mounting Type: Through Hole
Termination: Solder capability
Operating Temperature Range: Minimum -55°C to 125°C acceptable; the original part's -65°C to 130°C range is superior
Contact Finish - Mating: Gold or tin acceptable based on application requirements
RoHS Compliance: ROHS3 compliant substitutes preferred for regulatory alignment

Substitute parts are grouped into two categories: Molex KK254 series (active status, tin or gold finish options), Preci-Dip 350 series (active status, gold or tin finish with press-fit or solder termination), 3M 2300 series (active status, gold finish), and Mill-Max 350 series (active status, gold finish). All substitutes maintain the 2.54mm pitch, 4-position configuration, and through-hole mounting required for direct replacement.

Engineering Selection Recommendations

Primary Substitutes (Recommended)

The Molex KK254 series parts (0423751246, 0423751350, 0423752488, 0423752523) are active products with ROHS3 compliance and UL94 V-0 flammability ratings. These parts maintain the 2.54mm pitch, 4-position configuration, and through-hole solder termination. The 0423752523 variant offers gold finish at 30.0µin thickness, matching the original part's contact finish specification. Molex parts are available in high inventory quantities (727–23,912 pieces).

The Preci-Dip 350 series (350-10-104-00-013101, 350-10-104-01-666101, 350-80-104-00-013101, 350-80-104-01-666101) provides active alternatives with ROHS3 compliance, UL94 V-0 rating, and operating temperature range of -55°C to 125°C. The 350-10-104-00-013101 and 350-10-104-01-666101 variants feature gold finish; the 350-80 variants feature tin finish. Press-fit and solder termination options are available. Inventory ranges from 664 to 985 pieces.

Secondary Substitutes

The 3M 2304-6111-TB is an active product with gold finish and UL94 V-0 rating. However, it operates at -55°C to 105°C (narrower range than the original) and carries a 3A current rating versus the original 5A. RoHS non-compliance status requires evaluation against project requirements. Inventory is 791 pieces.

The Mill-Max 350-10-104-00-006000 is an active product with ROHS3 compliance but lacks specified operating temperature and current rating data. Contact shape is circular rather than square. This part is suitable only when mechanical compatibility with circular contacts is confirmed.

Compliance Considerations

All recommended substitutes maintain ROHS3 compliance and UL94 V-0 flammability ratings. The 3M 2304-6111-TB is RoHS non-compliant and should be avoided in applications requiring RoHS certification. All substitutes are classified as active products, ensuring long-term availability and supply chain stability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can I use a Molex KK254 part as a direct replacement for the 75160-156-04LF?

A: Yes, Molex KK254 series parts (0423751246, 0423751350, 0423752488, 0423752523) are direct mechanical and electrical replacements. All maintain 2.54mm pitch, 4-position configuration, through-hole mounting, and solder termination. The 0423752523 variant matches the original's gold contact finish specification at 30.0µin thickness. Verify contact finish requirements for your application, as some variants use tin finish.

Q: What is the difference between the Preci-Dip 350-10 and 350-80 series?

A: The primary difference is contact finish. The 350-10 series features gold finish; the 350-80 series features tin finish. Both maintain identical pitch, position count, mounting type, and termination. Select based on your application's corrosion resistance and solderability requirements. The 350-10-104-01-666101 and 350-80-104-01-666101 variants offer press-fit termination in addition to solder capability.

Q: Does the 3M 2304-6111-TB meet the original part's specifications?

A: The 3M part maintains mechanical compatibility (2.54mm pitch, 4 positions, through-hole, solder termination) but has operational limitations. Operating temperature range is -55°C to 105°C versus the original -65°C to 130°C. Current rating is 3A versus the original 5A. The part is RoHS non-compliant. Use only if your application operates within these narrower specifications and RoHS compliance is not required.

Q: Are circular contact shapes compatible with square contact applications?

A: Circular and square contact shapes are mechanically incompatible. The Mill-Max 350-10-104-00-006000 features circular contacts and should not be used as a replacement for the 75160-156-04LF, which requires square contacts. Verify contact shape compatibility before selection.

Q: What inventory levels are available for these substitutes?

A: Molex KK254 variants range from 727 to 23,912 pieces in stock. Preci-Dip 350 series variants range from 664 to 985 pieces. The 3M 2304-6111-TB has 791 pieces available. The Mill-Max 350-10-104-00-006000 has 773 pieces available. All are classified as new original stock.

Q: Which substitute offers the best thermal performance?

A: The Preci-Dip 350 series (all variants) and the original 75160-156-04LF both support -55°C to 125°C operating range. The original part extends to -65°C and 130°C, providing superior thermal performance. For applications requiring the original's full temperature range, no substitute fully matches these specifications. Evaluate whether your application requires operation at temperatures below -55°C or above 125°C.

Q: Are all substitutes RoHS compliant?

A: All substitutes except the 3M 2304-6111-TB are ROHS3 compliant. The 3M part is RoHS non-compliant. For applications requiring RoHS certification, select from Molex KK254 series, Preci-Dip 350 series, or Mill-Max 350-10-104-00-006000.
