Engineering Selection Recommendations

All identified substitute parts maintain Active product status and full RoHS3 or RoHS compliance, ensuring regulatory alignment with the main part. Selection among substitutes depends on specific application requirements:

Molex KK254 Series (0022284104, 0022284105): Both parts feature breakaway capability and square contact geometry. The 0022284105 offers higher inventory availability (11886 units) compared to 0022284104 (2070 units). Contact length specifications differ slightly between the two models, with 0022284105 providing 0.295" mating contact length versus 0022284104 at 0.320". Both use tin-plated posts and polyamide insulation material.

TE Connectivity AMPMODU Mod II (1-826629-0): This part provides the highest current rating at 5A and operates across -65°C to 105°C. It features brass contact material matching the main part and PBT insulation. The green insulation color distinguishes it from other options. Operating temperature lower bound extends 10°C below the main part specification.

Hirose A2 Series (A2-10PA-2.54DSA(71)): Offers 200V voltage rating, exceeding the main part's 150VDC specification. Operating temperature range is -55°C to 85°C, with the upper limit 40°C below the main part. Current rating matches at 3A. PBT insulation and brass contact material align with primary specifications.

Harwin M20 Series (M20-9731045, M20-9991045, M20-9991046): All three variants feature cuttable header design with polyamide PA6T insulation. M20-9731045 and M20-9991045 maintain gold mating contact finish, while M20-9991046 uses tin finish on both mating and post contacts. Operating temperature range spans -40°C to 105°C. M20-9991045 provides the highest inventory (5265 units) among Harwin options.

Selection should prioritize parts with operating temperature ranges encompassing the application environment and contact finish specifications matching circuit board requirements.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022284104 and 0022284105 be used interchangeably with the Preci-Dip 351-10-110-00-003101?

A: Both Molex parts share identical pitch (2.54mm), position count (10), mounting type (through hole), and termination (solder). The primary difference is contact length: 0022284104 provides 0.320" mating contact length while 0022284105 provides 0.295". Both are functionally compatible as substitutes, with selection depending on mating depth requirements in the specific application.

Q: What is the significance of the "breakaway" and "cuttable" features on substitute parts?

A: Breakaway and cuttable features allow individual positions to be separated from the header strip after assembly. The main part (351-10-110-00-003101) does not specify these features. Substitute parts with these capabilities provide additional design flexibility but remain fully compatible with applications requiring standard 10-position headers.

Q: Does the TE Connectivity 1-826629-0 operate at the same temperature range as the main part?

A: No. The TE Connectivity part operates from -65°C to 105°C, while the main part operates from -55°C to 125°C. The TE part's lower temperature limit extends 10°C below the main part, but the upper limit is 20°C lower. Applications requiring operation above 105°C must use the main part or other substitutes with higher temperature ratings.

Q: Why do some substitute parts have unspecified current and voltage ratings?

A: The Molex KK254 series (0022284104, 0022284105) do not provide explicit current or voltage ratings in the supplied data. However, both parts maintain UL94 V-0 flammability rating and are qualified for general purpose, automotive, medical, and telecommunications applications, indicating suitability for standard signal and low-power applications.

Q: Is the Harwin M20-9991046 with tin mating finish compatible with the gold-plated main part?

A: Yes. The M20-9991046 uses tin finish on both mating and post contacts, while the main part uses gold. Both finishes are standard for 2.54mm pitch headers and provide equivalent electrical performance. Contact finish selection depends on application requirements for corrosion resistance and contact wear characteristics rather than compatibility.

Q: What is the difference between the three Harwin M20 variants?

A: M20-9731045 and M20-9991045 both feature gold mating contact finish with 0.276" and 0.240" mating contact lengths respectively. M20-9991046 matches M20-9991045 in contact length (0.240") but uses tin finish on both mating and post contacts. All three operate from -40°C to 105°C and provide 3A per contact current rating.

Q: Can I substitute the Hirose A2-10PA-2.54DSA(71) in applications requiring -55°C operation?

A: The Hirose part operates from -55°C to 85°C, meeting the lower temperature requirement. However, applications requiring sustained operation above 85°C cannot use this part. The main part (351-10-110-00-003101) with -55°C to 125°C range provides broader temperature coverage.

Q: Are all substitute parts ROHS3 compliant?

A: Six of seven substitute parts are ROHS3 compliant. The TE Connectivity 1-826629-0 is listed as RoHS Compliant without specific ROHS3 designation. All parts meet RoHS requirements and are suitable for applications with RoHS compliance mandates.
