Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0010894103 are qualified based on the following critical parameters that determine functional interchangeability:

Primary Matching Criteria:

• Connector Type: Header, Breakaway
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 10
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute parts meet these core electrical and mechanical requirements. Variations in contact length, insulation height, insulation material composition, and contact finish thickness are within acceptable tolerances for equivalent performance in the specified applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—Molex 0010894103, TE Connectivity 5-146309-5, and Hirose A1-10PA-2.54DS(71)—are active products with current manufacturing status and full compliance with RoHS and UL94 V-0 flammability requirements. Selection between these parts is based on design requirements and application constraints:

Molex 0010894103 is the primary specification. It provides a baseline reference for 2.54mm pitch, 10-position, right-angle header applications with polyester glass-filled insulation.

TE Connectivity 5-146309-5 offers extended operating temperature range (-65°C to 105°C) and specified current rating (3A), making it suitable for applications requiring broader thermal performance. The thermoplastic glass-filled insulation provides alternative material properties.

Hirose A1-10PA-2.54DS(71) provides specified voltage rating (200V) and current rating (3A) with PBT insulation material. Operating temperature range is -55°C to 85°C. This part is suitable for applications with defined voltage and current requirements.

All parts maintain equivalent mechanical compatibility through matching pitch, position count, row configuration, and mounting orientation. Compliance certifications and moisture sensitivity levels are consistent across all options.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the Molex 0010894103?

A: Substitution is based on matching the core electrical and mechanical parameters: 0.100" (2.54mm) pitch, 10 positions in 2 rows, male pin contact type, through-hole right-angle mounting, solder termination, gold-plated mating contacts, tin-plated posts, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity. All identified substitutes meet these criteria.

Q: Are there differences in contact length between the main part and substitutes?

A: Yes. The Molex 0010894103 has a mating contact length of 0.320" (8.13mm), the TE Connectivity part is 0.318" (8.08mm), and the Hirose part is 0.236" (6.00mm). These variations are within acceptable tolerances for equivalent mating performance in standard board-to-board applications. Post contact lengths vary slightly (0.110" to 0.118"), which is acceptable for solder termination compatibility.

Q: What is the difference in insulation material between these parts?

A: The Molex part uses polyester glass-filled insulation, the TE Connectivity part uses thermoplastic glass-filled insulation, and the Hirose part uses PBT (polybutylene terephthalate). All materials meet UL94 V-0 flammability requirements. Material selection depends on specific application thermal and chemical exposure requirements.

Q: Do all parts have the same operating temperature range?

A: No. The Molex 0010894103 does not specify an operating temperature range. The TE Connectivity 5-146309-5 operates from -65°C to 105°C, and the Hirose A1-10PA-2.54DS(71) operates from -55°C to 85°C. Application temperature requirements should guide part selection when thermal performance is critical.

Q: Are current and voltage ratings specified for all parts?

A: The Molex 0010894103 does not specify current or voltage ratings. The TE Connectivity part is rated for 3A with no voltage specification. The Hirose part is rated for 3A at 200V. Applications requiring defined electrical performance specifications should reference the TE Connectivity or Hirose parts.

Q: What is the packaging difference between these parts?

A: The Molex 0010894103 is supplied in tube packaging. Both the TE Connectivity 5-146309-5 and Hirose A1-10PA-2.54DS(71) are supplied in tray packaging. Packaging affects handling, storage, and automated assembly considerations.

Q: Are all parts RoHS compliant?

A: Yes. The Molex and Hirose parts are ROHS3 compliant. The TE Connectivity part is RoHS compliant. All parts meet current environmental compliance standards for electronic component manufacturing.
