Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original Molex 0702800928. Selection between substitute options depends on application-specific requirements:

TSW Series Selection (Samtec Inc.): The TSW-150-14-G-D, TSW-150-14-L-D, and TSW-150-14-T-D are direct functional replacements suitable for standard board-to-board header applications. These parts provide identical mating contact geometry and pitch spacing. The TSW-150-14-G-D offers gold post finish for enhanced corrosion resistance. The TSW-150-14-L-D provides tin post finish for cost optimization. The TSW-150-14-T-D uses tin mating finish and operates within a -55°C to 105°C temperature range, suitable for general industrial applications.

ZW Series Selection (Samtec Inc.): The ZW-50 series connectors are spacer-based solutions designed for multi-level board stacking. These parts accommodate variable stack heights and extended post lengths. The ZW-50-08-S-D-260-145 provides a 0.260" stack height with 0.125" post length. The ZW-50-11-G-D-250-520 offers extended overall pin length (0.930") with 0.160" post length for applications requiring deeper board penetration. The ZW-50-15-G-D-255-235 provides 0.255" stack height with 0.140" post length for moderate stacking applications.

All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity rating and UL94 V-0 flammability compliance where specified, ensuring compatibility with automotive, medical, and telecommunications environments.

Frequently Asked Questions (FAQ)

Q: Can TSW-150-14-G-D replace the Molex 0702800928 in a standard board-to-board application?

A: Yes. Both connectors share identical 100-position, 2-row configuration with 0.100" (2.54mm) pitch and 0.320" mating contact length. The TSW-150-14-G-D is a direct functional replacement for standard header applications. The primary difference is the contact material (phosphor bronze vs. copper alloy) and insulation material (PBT vs. LCP), which do not affect electrical or mechanical compatibility in standard applications.

Q: What is the difference between TSW-150-14-G-D, TSW-150-14-L-D, and TSW-150-14-T-D?

A: These three parts differ in contact finish specifications. TSW-150-14-G-D features gold post finish for enhanced corrosion resistance. TSW-150-14-L-D uses tin post finish for cost reduction. TSW-150-14-T-D applies tin mating finish instead of gold and operates at a lower maximum temperature (-55°C to 105°C vs. -55°C to 125°C). All three maintain identical position count, pitch, and mating contact geometry.

Q: When should ZW series connectors be used instead of TSW series?

A: ZW series connectors are spacer-based solutions for multi-level board stacking applications. Use ZW series when your design requires variable stack heights, extended post lengths for deeper board penetration, or when accommodating multiple connector levels in a single assembly. Standard single-level board-to-board applications should use TSW series headers.

Q: Are the ZW-50-08-S-D-260-145, ZW-50-11-G-D-250-520, and ZW-50-15-G-D-255-235 interchangeable?

A: No. These ZW series parts differ in overall pin length, post length, and stack height. ZW-50-08-S-D-260-145 provides 0.260" stack height with 0.125" post length. ZW-50-11-G-D-250-520 offers 0.930" overall pin length with 0.160" post length for extended penetration. ZW-50-15-G-D-255-235 provides 0.255" stack height with 0.140" post length. Selection depends on specific board stacking geometry and post length requirements.

Q: Do all substitute parts meet the same compliance standards as the Molex 0702800928?

A: All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. TSW series parts specify UL94 V-0 flammability rating. ZW series parts do not specify flammability rating in the provided data. Verify flammability compliance with the manufacturer if UL94 V-0 certification is required for your application.

Q: What is the impact of contact material differences (copper alloy vs. phosphor bronze)?

A: Both copper alloy and phosphor bronze are acceptable contact materials for 0.100" pitch connectors. Phosphor bronze (used in TSW and ZW series) provides improved spring characteristics and durability in high-cycle mating applications. Copper alloy (used in Molex 0702800928) offers cost efficiency. For standard applications, both materials are functionally equivalent.

Q: Can I use a substitute part with a different insulation material (PBT vs. LCP)?

A: Yes. Both polybutylene terephthalate (PBT) and liquid crystal polymer (LCP) are acceptable insulation materials for this connector category. PBT (used in TSW and ZW series) provides good mechanical properties and cost efficiency. LCP (used in Molex 0702800928) offers superior dimensional stability and lower moisture absorption. For standard applications, both materials maintain electrical and mechanical compatibility.
