09031965921 DIN 41612 96-Position Backplane Connector Header

Part Overview

The HARTING 09031965921 is a 96-position DIN 41612 connector header with male pins, designed for through-hole PCB mounting in right-angle configuration. This component serves as a backplane interface connector in industrial and telecommunications equipment. The part is currently active in production with 884 units in stock.

Substitute parts are necessary when addressing supply chain constraints, obsolescence planning, or when specific performance characteristics of alternative manufacturers better match application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 09031965921 is determined by the following mandatory parameters:

• 96-position connector configuration
• 0.100" (2.54mm) pitch spacing
• 3-row DIN 41612 Style C layout
• Through-hole, right-angle mounting
• Solder termination
• Operating temperature range of -55°C to 125°C minimum
• UL94 V-0 flammability rating
• RoHS compliance

The substitute parts listed below meet these core electrical and mechanical requirements. Variations in contact finish, contact finish thickness, current rating, and specific product status do not preclude substitution when the above parameters align.

Parameter Comparison

Engineering Selection Recommendations

0850030567 (Molex): This part meets all core substitution parameters and maintains the full -55°C to 125°C operating range. However, the product status is listed as obsolete, indicating this part is no longer in active production. Selection should be limited to applications where existing inventory is available and long-term supply is not a requirement.

DIN-096CPC-SR1-KR (3M): This part is active in production with the highest inventory availability (2400 units). It meets all core electrical and mechanical requirements and maintains the full -55°C to 125°C operating range. The connector type is specified as plug rather than header; verify mechanical compatibility with mating receptacles in your application. Current rating is specified at 3A.

PCN10-96P-2.54DS(72) (Hirose): This part is active in production and meets all core substitution parameters. The operating temperature range is limited to -55°C to 85°C, which is narrower than the main part. Current rating is specified at 2A. Selection is appropriate for applications operating within this temperature envelope.

PCN10-96P-2.54DS(77) (Hirose): This part carries a Last Time Buy status, indicating limited future availability. The operating temperature range is limited to -55°C to 85°C. Current rating is specified at 2A. This part should be selected only when existing inventory meets project requirements and no long-term supply is needed.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 09031965921 with the DIN-096CPC-SR1-KR if my application requires a header connector?

A: The DIN-096CPC-SR1-KR is specified as a plug connector, not a header. While both are 96-position DIN 41612 Style C connectors with identical pitch and row configuration, the connector type difference affects mechanical mating. Verify that your PCB receptacle is designed to accept a plug connector before substitution.

Q: What is the difference between the two Hirose parts, PCN10-96P-2.54DS(72) and PCN10-96P-2.54DS(77)?

A: Both Hirose parts share identical electrical and mechanical specifications: 96 positions, 0.100" pitch, 3 rows, Style C, through-hole right-angle mounting, and 2A current rating. The primary difference is product status: PCN10-96P-2.54DS(72) is active in production, while PCN10-96P-2.54DS(77) is Last Time Buy. For new designs, PCN10-96P-2.54DS(72) is preferred due to ongoing availability.

Q: Why do the Hirose parts have a lower maximum operating temperature than the main part?

A: The Hirose PCN10 series is specified with a maximum operating temperature of 85°C, compared to 125°C for the HARTING 09031965921 and Molex 0850030567. If your application requires operation above 85°C, the Hirose parts are not suitable substitutes. Verify your application's thermal requirements before selection.

Q: Is the Molex 0850030567 still available for new designs?

A: The Molex 0850030567 is listed as obsolete, meaning it is no longer in active production. While 923 units are currently in stock, this part should not be selected for new designs requiring long-term supply. The 3M DIN-096CPC-SR1-KR or active Hirose PCN10-96P-2.54DS(72) are preferred alternatives.

Q: What does the contact finish difference mean for my application?

A: The main part 09031965921 does not specify a contact finish. The substitute parts offer gold plating at varying thicknesses: Molex at 24.0µin (0.61µm), 3M at 30.0µin (0.76µm), and Hirose at 8.00µin (0.203µm). Gold plating improves corrosion resistance and contact reliability. If your application operates in corrosive environments or requires enhanced contact performance, gold-plated alternatives provide additional protection.

Q: Can I use these parts interchangeably in existing designs?

A: Mechanical and electrical interchangeability depends on your specific PCB layout and mating connector type. All listed parts share the same 96-position, 0.100" pitch, 3-row DIN 41612 Style C configuration. However, verify that your PCB footprint accommodates the right-angle mounting orientation and that your mating connector accepts the specific connector type (header vs. plug). Test with a sample unit before full production transition.
