Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HARTING 09037966821 is determined by strict equivalence across the following critical parameters:

• Connector Series and Standard: DIN 41612 compliance
• Connector Configuration: 96-position receptacle with female sockets
• Physical Layout: 3-row arrangement, Style C, 0.100" (2.54mm) pitch
• Mounting and Termination: Through-hole PCB mounting with wire wrap termination
• Contact System: Gold-plated contacts for signal integrity
• Environmental Compliance: UL94 V-0 flammability rating, ROHS3 compliance, MSL 1 rating

The substitute part HARTING 09032966878 maintains full equivalence across all mechanical and electrical parameters required for direct substitution in backplane connector applications.

Parameter Comparison

Engineering Selection Recommendations

The HARTING 09032966878 is the direct substitute for the obsolete 09037966821. Both components maintain identical mechanical interfaces, electrical contact configurations, and environmental compliance certifications. The substitute part is currently in active production status with higher inventory availability (1088 units versus 746 units for the main part).

The insulation material differs between the two parts (PBT versus thermoplastic), though both maintain UL94 V-0 flammability compliance. This material variation does not affect functional compatibility in standard backplane connector applications. Both parts satisfy ROHS3 compliance and REACH unaffected status requirements.

For new designs or system replacements, the 09032966878 is the appropriate selection due to its active product status and continued manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 09032966878 directly replace the 09037966821 in existing assemblies?

A: Yes. Both connectors maintain identical 96-position DIN 41612 configurations with matching pitch, row arrangement, mounting type, and termination method. The connectors are mechanically and electrically interchangeable.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The main part 09037966821 is obsolete and no longer manufactured. The substitute 09032966878 is in active production, ensuring long-term availability and supply chain continuity for maintenance and new applications.

Q: Are there differences in operating temperature or current ratings between these parts?

A: The main part specifies -55°C to 125°C operating range and 2A current rating. The substitute part does not specify these parameters in the provided data. For applications requiring confirmed temperature or current specifications, these parameters should be verified against the substitute part's complete technical documentation.

Q: How do the insulation materials compare?

A: The main part uses polybutylene terephthalate (PBT) glass-filled material, while the substitute uses thermoplastic glass-filled material. Both achieve UL94 V-0 flammability compliance. The material difference does not affect connector function in standard backplane applications.

Q: What packaging is available for the substitute part?

A: The substitute part 09032966878 is supplied in bulk packaging, compared to the main part which does not specify packaging type.
