Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 5-146309-6 are identified based on strict alignment of critical electrical and mechanical parameters. The substitution logic requires equivalence in the following parameters:

Critical Matching Parameters:

• Number of Positions: 12
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Contact Type: Male Pin
• Termination: Solder
• Current Rating: 3A
• Material Flammability Rating: UL94 V-0
• RoHS Compliance: Yes

The Hirose Electric Co Ltd part number A1-12PA-2.54DS(71) satisfies all critical matching parameters, establishing it as a valid substitute. Both connectors feature identical position counts, row configurations, pitch spacing, and mounting orientation. Both maintain equivalent current handling capacity and flammability compliance. Variations in contact length, insulation height, contact finish thickness, and operating temperature range do not preclude substitution when the application requirements fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 5-146309-6 and Hirose A1-12PA-2.54DS(71) maintain Active product status, ensuring continued availability and manufacturer support. Both connectors carry RoHS Compliance certification and UL94 V-0 flammability ratings, meeting regulatory requirements for industrial and consumer applications.

The TE Connectivity part operates across a wider temperature range (-65°C to 105°C) compared to the Hirose substitute (-55°C to 85°C). Applications requiring operation at temperatures below -55°C or above 85°C must retain the TE Connectivity original part. For applications operating within the -55°C to 85°C window, the Hirose substitute provides equivalent functionality.

The Hirose part specifies a 200V voltage rating, while the TE Connectivity part does not provide a voltage specification. Applications with defined voltage requirements should reference the Hirose specification as a minimum rating for the substitute.

Contact length variations between the two parts (mating contact length of 0.318" versus 0.236") require verification against mating connector specifications to ensure proper contact engagement and retention force. Post length differences (0.110" versus 0.118") may affect PCB layout and component clearance considerations.

Both parts feature identical pitch spacing (0.100"), row configuration (2 rows), position count (12), and current rating (3A), establishing mechanical and electrical interchangeability within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if a connector can substitute for the TE Connectivity 5-146309-6?

A: Substitution requires matching the following parameters: 12 positions in 2 rows, 0.100" (2.54mm) pitch spacing, through-hole right-angle mounting, male pin contact type, solder termination, 3A current rating, UL94 V-0 flammability rating, and RoHS compliance. The Hirose A1-12PA-2.54DS(71) meets all these criteria.

Q: Can the Hirose A1-12PA-2.54DS(71) be used in applications requiring operation below -55°C?

A: No. The Hirose substitute is rated for -55°C to 85°C operation. Applications requiring temperatures below -55°C must use the TE Connectivity 5-146309-6, which operates from -65°C to 105°C.

Q: Are there differences in contact length between these connectors?

A: Yes. The TE Connectivity part has a mating contact length of 0.318" (8.08mm), while the Hirose substitute has 0.236" (6.00mm). Post lengths also differ: 0.110" versus 0.118" respectively. These differences require verification against mating connector specifications to ensure proper engagement.

Q: Do both connectors meet RoHS compliance requirements?

A: Yes. Both the TE Connectivity 5-146309-6 and Hirose A1-12PA-2.54DS(71) are RoHS Compliant with Moisture Sensitivity Level 1 (Unlimited).

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

A: The TE Connectivity part uses Thermoplastic, Glass Filled insulation material, while the Hirose substitute uses Polybutylene Terephthalate (PBT). Both materials achieve UL94 V-0 flammability rating.

Q: Is the Hirose part suitable for applications with 200V voltage requirements?

A: The Hirose A1-12PA-2.54DS(71) specifies a 200V voltage rating. The TE Connectivity 5-146309-6 does not provide a voltage specification. For applications with defined voltage requirements, the Hirose specification should be referenced as a minimum rating.

Q: Can these connectors be used interchangeably in new designs?

A: Interchangeability depends on application-specific requirements. Both connectors share identical pitch, position count, row configuration, and current rating. However, differences in operating temperature range, contact length, and insulation material require evaluation against specific design constraints before selecting either connector for new applications.

Q: What is the current rating for both connectors?

A: Both the TE Connectivity 5-146309-6 and Hirose A1-12PA-2.54DS(71) are rated for 3A current per contact.
