Engineering Selection Recommendations

Active Status Parts (Preferred for New Designs):

The MTSW-104-07-T-S-220, 0022284040, 5-146274-4, and 68000-404HLF are all active products with current manufacturing support. These parts are suitable for new designs and ongoing production.

0022284040 (Molex KK254) provides direct substitution with equivalent electrical and mechanical characteristics. ROHS3 compliance and REACH unaffected status align with the primary part.

5-146274-4 (TE Connectivity AMPMODU Mod II) offers extended operating temperature range (-65°C to 105°C) compared to the primary part (-55°C to 105°C). This part is suitable when wider temperature performance is required. RoHS compliance is confirmed, though ROHS3 status differs from the primary part.

68000-404HLF (Amphenol ICC BERGSTIK® II) provides the widest operating temperature range (-65°C to 125°C) among active alternatives. REACH affected status requires verification for applications subject to REACH regulations.

Obsolete Status Parts (Not Recommended for New Designs):

75160-102-04LF and 69190-404 are obsolete products. These parts are not suitable for new designs but may be considered only for legacy system maintenance or repair when no active alternatives are available. Both parts carry REACH affected status, which may present regulatory compliance challenges.

Frequently Asked Questions (FAQ)

Q: Can I substitute the MTSW-104-07-T-S-220 with any of the listed parts?

A: Yes, all listed parts meet the core substitution criteria: 0.100" (2.54mm) pitch, 4 positions, 1 row, male pin contacts, through-hole mounting, solder termination, and push-pull fastening. However, active status parts (0022284040, 5-146274-4, 68000-404HLF) are preferred for new designs. Obsolete parts (75160-102-04LF, 69190-404) should only be used for legacy applications.

Q: What are the key differences in contact dimensions?

A: Contact length variations exist across substitutes. The MTSW-104-07-T-S-220 has a mating contact length of 0.220" (5.59mm) and post length of 0.110" (2.79mm). Substitutes range from 0.095" to 0.318" for mating contact length and 0.095" to 0.135" for post length. These variations may affect board-to-board spacing and mating depth. Verify mechanical compatibility with your specific application.

Q: Are there temperature rating differences I should consider?

A: Yes. The primary part operates from -55°C to 105°C. The TE Connectivity 5-146274-4 extends the lower limit to -65°C. The Amphenol ICC parts (68000-404HLF, 75160-102-04LF, 69190-404) extend the upper limit to 125°C or 130°C. Select based on your application's thermal requirements.

Q: What is the difference between tin and gold contact finishes?

A: The primary part and most substitutes use tin contact finish on mating surfaces. The 75160-102-04LF uses gold (GXT™) finish with 30.0µin thickness. Gold provides superior corrosion resistance and is suitable for applications requiring extended shelf life or harsh environments. Tin is standard for general-purpose applications.

Q: Do all parts have the same insulation material?

A: No. The primary part uses polyester glass-filled insulation. Substitutes use polyamide (Molex), liquid crystal polymer (TE Connectivity), or thermoplastic (Amphenol ICC). These materials have different thermal and mechanical properties. Verify compatibility with your PCB assembly process and operating environment.

Q: What does REACH affected status mean?

A: REACH affected status indicates the part may contain substances of concern under EU REACH regulations. Parts 68000-404HLF and 75160-102-04LF carry this designation. If your application is subject to REACH compliance requirements, select REACH unaffected parts: MTSW-104-07-T-S-220, 0022284040, 5-146274-4, or 69190-404.

Q: Can I use the obsolete parts in production?

A: Obsolete parts (75160-102-04LF, 69190-404) are not recommended for new production designs due to limited availability and lack of manufacturing support. Use only for legacy system maintenance or repair when active alternatives are unavailable. Verify long-term supply before committing to obsolete parts.

Q: What is the current rating difference between parts?

A: The primary part and most substitutes are rated for 3A. The 75160-102-04LF is rated for 5A, providing higher current capacity. Select based on your circuit's current requirements. Higher-rated parts can be used in lower-current applications without issue.
