Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compliance):

68000-402HLF and 69190-402HLF are the most direct substitutes. Both are active production parts with RoHS compliance. The 68000-402HLF offers a shorter post length (0.095") suitable for applications with limited PCB depth, while 69190-402HLF provides a longer post (0.120") for applications requiring deeper board penetration. Both support the same 3A current rating and maintain tin contact finish compatibility.

Extended Temperature Range Alternatives:

68002-402HLF extends the operating temperature to -65°C ~ 130°C, compared to the original -55°C ~ 105°C specification. This part is suitable for applications requiring enhanced thermal performance while maintaining all other electrical and mechanical parameters.

Gold Contact Finish Options:

68000-102HLF and 69190-202HLF provide gold or gold GXT™ contact finish on the mating surface. These parts are specified for applications requiring improved corrosion resistance or enhanced contact reliability in harsh environments. Both maintain RoHS compliance and active production status.

Avoid Obsolete Parts:

68000-402 and 69190-402 are marked obsolete and should not be selected for new designs, despite RoHS compliance in 69190-402.

Molex Alternative:

0878910206 from Molex (KK254 series) provides a functionally equivalent 2-position 2.54mm pitch header with tin finish. This part is suitable when Molex component standardization is required within a design ecosystem.

Frequently Asked Questions (FAQ)

Q: Can I substitute MTSW-102-07-T-S-220 with 68000-402HLF?

A: Yes. Both parts share identical pitch (0.100"), position count (2), contact type (male pin), mounting method (through hole), and current rating (3A). The primary difference is contact post length: MTSW-102-07-T-S-220 has 0.110" post length while 68000-402HLF has 0.095". This difference affects PCB penetration depth. Verify your PCB thickness and solder pad design accommodate the shorter post length.

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

A: Tin contact finish (MTSW-102-07-T-S-220, 68000-402HLF, 69190-402HLF) provides standard electrical conductivity and is suitable for general-purpose applications. Gold or gold GXT™ finish (68000-102HLF, 69190-202HLF) offers enhanced corrosion resistance and improved contact reliability in high-humidity, high-vibration, or harsh chemical environments. Gold finish does not affect electrical compatibility but may impact cost and lead time.

Q: Why do some substitute parts have longer post lengths?

A: Contact post length determines how deeply the connector penetrates the PCB during soldering. Longer posts (0.120" to 0.150") are specified for applications with thicker PCBs or when additional mechanical support is required. Shorter posts (0.095") are used in space-constrained designs or thin PCB applications. Post length does not affect electrical performance but must be verified against your PCB thickness and solder joint design.

Q: Is 0878910206 from Molex electrically compatible?

A: Yes. The Molex 0878910206 maintains the same 0.100" pitch, 2-position configuration, male pin contact type, and push-pull fastening. It is suitable as a substitute when Molex standardization is required. Verify packaging requirements, as this part is supplied in trays rather than bulk or bags.

Q: Can I use 68031-102HLF as a substitute?

A: 68031-102HLF is not recommended as a direct substitute. While it maintains 0.100" pitch and 2-position configuration, it specifies 5A current rating (versus 3A) and 110V voltage rating. This part is designed for higher-power applications and may not be cost-effective for standard 3A designs. Use only if your application requires the higher current capacity.

Q: What does RoHS3 compliance mean for this connector?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. MTSW-102-07-T-S-220 is ROHS3 compliant. Most substitute parts listed (68000-402HLF, 68001-402HLF, 68002-402HLF, 69190-402HLF) are also RoHS compliant. Avoid 68000-402, which is RoHS non-compliant, for new designs subject to RoHS regulations.

Q: Should I use obsolete parts like 68000-402 or 69190-402?

A: No. Obsolete parts should not be selected for new designs. While limited inventory may be available, obsolete parts lack manufacturer support, may have supply discontinuity, and complicate long-term product maintenance. Select from active production parts: 68000-402HLF, 68001-402HLF, 68002-402HLF, or 69190-402HLF.

Q: How does operating temperature range affect substitution?

A: The original MTSW-102-07-T-S-220 operates from -55°C to 105°C. Substitute parts like 68000-402HLF and 69190-402HLF extend this to -65°C ~ 125°C or -65°C ~ 130°C. A wider temperature range does not compromise compatibility; it simply provides additional thermal margin. Select extended-range parts if your application experiences temperature extremes or requires design margin for thermal cycling.
