Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 973027 is determined by alignment of the following critical parameters:

Mandatory Compatibility Parameters:

• Pitch specification: 0.098" (2.50mm)
• Mounting technology: Through-hole press-fit termination
• Contact finish: Gold plating
• Connector category: Backplane connectors
• Connector gender: Male pins
• RoHS3 compliance status

Position Configuration Consideration: The 973027 provides 90 total positions (9 rows × 10 columns). Substitute components must accommodate the required position count or provide modular configurations that satisfy the electrical and mechanical interface requirements of the original design.

The identified substitute part 6469083-1 shares the core pitch, termination method, contact finish, and compliance certifications. However, this substitute provides 60 positions (6 rows × 10 columns), representing a reduced position count that requires design-level evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

Active Component Status: The substitute part 6469083-1 holds active product status with TE Connectivity AMP Connectors, ensuring ongoing availability, technical support, and manufacturing continuity. The original 973027 is classified as obsolete, making transition to an active equivalent necessary for new production and long-term supply chain stability.

Compliance Alignment: Both components maintain ROHS3 compliance and MSL Level 1 (unlimited moisture sensitivity) ratings, satisfying regulatory requirements for electronics manufacturing. The substitute part provides specified electrical parameters (0.700A current rating, 250V voltage rating) not documented for the original component.

Pitch and Termination Compatibility: The 0.098" (2.50mm) pitch and press-fit through-hole termination are identical between the original and substitute, ensuring mechanical and electrical interface compatibility at the PCB level.

Position Count Variance: The substitute provides 60 positions versus the original 90 positions. Applications requiring the full 90-position configuration must evaluate whether multiple 60-position units can be deployed in parallel, or whether alternative multi-position backplane connectors from the Z-PACK HM-Zd series are required to meet position requirements.

Temperature Operating Range: The substitute operates across -65°C to 105°C, compared to the original -55°C to 125°C range. Applications requiring operation above 105°C or below -65°C must confirm compatibility with the substitute's thermal specifications.

Frequently Asked Questions (FAQ)

Q: Can the 6469083-1 directly replace the 973027 in existing designs?

A: Direct replacement is possible only if the application requires 60 or fewer positions. The 973027 provides 90 positions (9 rows × 10 columns), while the 6469083-1 provides 60 positions (6 rows × 10 columns). Designs utilizing all 90 positions require alternative solutions or multiple substitute units.

Q: What are the key compatibility criteria for substitution?

A: Substitution is based on matching pitch (0.098" / 2.50mm), mounting type (through-hole), termination method (press-fit), contact finish (gold), and compliance certifications (ROHS3). The 6469083-1 satisfies all these criteria.

Q: Does the substitute part support the same operating temperature range?

A: No. The 973027 operates from -55°C to 125°C, while the 6469083-1 operates from -65°C to 105°C. Applications requiring operation above 105°C must verify compatibility or identify alternative components.

Q: What is the difference between "Male Pins" and "Male Pins and Blades"?

A: The 973027 features male pins only, while the 6469083-1 includes both male pins and blades. This structural difference may affect mating interface compatibility depending on the receptacle design in the target application.

Q: Are there packaging differences between these components?

A: Yes. The 973027 is supplied in trays, while the 6469083-1 is supplied in tubes. Packaging selection may impact handling, storage, and automated assembly processes.

Q: What electrical specifications should be verified for the substitute?

A: The 6469083-1 is rated for 0.700A current and 250V voltage. The original 973027 does not specify these parameters. Confirm that the substitute's electrical ratings meet or exceed the application's power requirements.

Q: Is the substitute part actively manufactured?

A: Yes. The 6469083-1 holds active product status with TE Connectivity AMP Connectors, ensuring ongoing manufacturing and availability. The original 973027 is obsolete and no longer produced.
